The 2014 Evidence -Based Guideline for the Management of  High Blood Pressure In Adults : Report From the Panel Members Appointed to the Eighth Joint National Committee ( JNC 8) recommends several major changes from the JNC 7 report ( 1 , 2 ) . The 2014 guideline is based on a systematic review of r and omized , controlled trials ( RCTs ) by a multidisciplinary panel using a process informed by Institute of Medicine recommendations for guideline development ( 3 ) . Although there was almost unanimous agreement on nearly all recommendations , a minority of the panel ( the authors of this commentary ) disagreed with the recommendation to increase the target systolic blood pressure ( SBP ) from 140 to 150 mm Hg in persons aged 60 years or older without diabetes mellitus ( DM ) or chronic kidney disease ( CKD ) . This target guides both the initiation of therapy and treatment goals . Although this issue has major clinical and public health implication s , the guideline only briefly summarized the concerns underlying the minority opinion to maintain the target of less than 140 mm Hg . The Institute of Medicine recommendation for guideline development encourages guidelines to provide a description and explanation of any differences of opinion regarding the recommendation ( 3 ) . This summarizes the evidence and rationale underlying the minority opinion to maintain the SBP target of 140 mm Hg or lower in persons aged 60 years or older until there is greater certainty of the risks and benefits of a higher target . First , increasing the target will probably reduce the intensity of antihypertensive treatment in a large population at high risk for cardiovascular disease ( CVD ) ( Table 1 ) . The higher SBP goal would apply to some of the groups at highest cardiovascular risk , such as African Americans , hypertensive patients with multiple CVD risk factors other than DM or CKD , and those with clinical CVD . Second , the evidence supporting increasing the SBP target from 140 to 150 mm Hg in persons aged 60 years or older was insufficient and inconsistent with the evidence supporting the panel 's recommendations for an SBP target of less than 140 mm Hg in persons younger than 60 years and those aged 60 years or older with DM or CKD . Third , the higher SBP goal in individuals aged 60 years or older may reverse the decades-long decline in CVD , especially stroke mortality ( 4 ) . In the absence of definitive evidence defining the optimum SBP target , observational studies and RCT data that the panel did not systematic ally review more strongly support the SBP goal of less than 140 mm Hg , especially in high-risk individuals . Other recent guideline groups review ing similar evidence have recommended a goal of less than 140 mm Hg , particularly in persons aged 80 years or younger ( 59 ) . Table 1 . U.S. Cardiovascular Disease Death Rates for Persons Younger and Older Than 65 y Persons Aged 60 Years or Older With Hypertension and SBP Controlled to 140 mm Hg or Lower More than half of the 72 million persons with hypertension in the United States are aged 60 years or older ( 10 , 11 ) . Among these individuals , the 2014 guideline recommends the SBP goal of 140 mm Hg or lower only for those with DM and those younger than 70 years with CKD ( 2 ) . Although the prevalence of hypertension in this age group ( 65 % to 67 % ) did not change between 1999 and 2010 , the percentage with adequate blood pressure control increased from 27.4 % ( 19992000 ) to 50.5 % ( 20112012 ) , with 82.2 % now receiving antihypertensive medications ( 10 , 12 ) . Data from NHANES ( National Health and Nutrition Examination Survey ) from 2001 to 2008 show that among treated and untreated hypertensive adults aged 60 years or older , median SBPs were 136 mm Hg and 152 mm Hg , respectively ( 13 ) , and SBPs have been decreasing in this age group over the past 5 decades ( Figure ) ( 4 ) . Thus , a target of less than 150 mm Hg would likely increase blood pressures in the treated hypertensive population and would suggest that nearly half of the untreated hypertensive patients in this age range should remain untreated . The large population at high risk for CVD , with most currently at an SBP of 140 mm Hg or lower , creates concern that a higher SBP target will adversely affect public health . Figure . Smoothed weighted frequency distribution , median , and 90th percentile of systolic blood pressure for persons aged 60 to 74 y : United States , 19592010 . Reproduced from Lackl and and colleagues ( 4 ) . NHANES = National Health and Nutrition Examination Survey ; NHES = National Health Examination Survey . High Risk in Persons With the Higher Goal Age substantially increases risk for cardiovascular events ( Table 1 ) , so differences in cardiovascular risk do not justify different targets for patients older and younger than 60 years . The risk range for white and African American men aged 60 years is 9 % to 30 % , depending on risk factor profile . For men of both ethnicities who are aged 70 years or older and have SBP controlled to 140 mm Hg , even without clinical CVD or DM , the 10-year risk exceeds 20 % ( 14 ) . Thus , on the basis of absolute risk , using an age threshold of 60 years to define eligibility for less aggressive treatment lacks consistency . Persons aged 60 to 79 years are at higher risk than those who are younger , even if the younger persons have DM . Insufficient Evidence for Differential Hypertension Treatment Benefit for Patients Older and Younger Than 60 Years The 2014 guideline panel failed to identify evidence of differential benefits or harms of treatment using an SBP goal of 140 mm Hg with an age threshold of 60 years . There is little RCT evidence of risk or benefit in treating persons younger than 60 years to this target , except in those with diastolic hypertension . The guideline indicates that no qualifying evidence was found comparing an SBP less than 140 mm Hg to any other SBP goal for persons younger than 60 years ( 2 ) . However , in persons aged 60 years or older , the SHEP ( Systolic Hypertension in the Elderly Program ) trial showed benefit of treating hypertension to an SBP goal between 140 and 145 mm Hg ( Table 2 ) ( 15 ) . HYVET ( Hypertension in the Very Elderly Trial ) found a benefit of an SBP target of less than 150 mm Hg on health outcomes , including mortality in persons aged 80 years or older ( 16 ) . Patients in the HYVET treatment group achieved an SBP of 144 mm Hg at 2 years compared with 159 mm Hg in the control group , and blood pressures continued to decrease in both groups until the end of the trial . Therefore , HYVET and the SHEP trial provide evidence that reducing SBP to around 140 mm Hg has substantial benefit without major harm in older persons . Thus , the best evidence available for an SBP target around 140 mm Hg , which meets the guideline RCT criteria , is in persons older than 60 years . The lack of benefit seen in 2 Japanese trials in older individuals ( JATOS [ Japanese Trial to Assess Optimal Systolic Blood Pressure in Elderly Hypertensive Patients ] [ 17 ] and the VALISH [ Valsartan in Elderly Isolated Systolic Hypertension ] trial [ 18 ] ) was cited by some to rationalize the higher SBP target , but these trials were underpowered ( Table 2 ) . The SHEP trial and HYVET together reported 365 strokes and more than 285 coronary heart disease events , whereas JATOS and the VALISH trial only had a combined total of 125 strokes and 67 coronary heart disease events . In addition , the much larger FEVER ( Felodipine Event Reduction ) trial ( 19 ) did not meet criteria for inclusion in the panel 's deliberation ( Table 2 ) . This trial , which was conducted in a Chinese population ( age range , 50 to 79 years ; mean age , 62 years ) , reported a significant 27 % reduction in its primary outcome , as well as significant reductions in all CVD , total mortality , coronary heart disease , and heart failure in patients treated to an SBP of 137 mm Hg with a thiazide diureticcalcium-channel blocker combination versus 143 mm Hg with a thiazide diuretic plus placebo ( 19 ) . Table 2 . Trials Comparing Different Systolic Blood Pressure Thresholds In addition , generalizability of the Japanese trials to other population s of patients older than 60 years , such as African Americans , is uncertain . African Americans are at highest risk for all complications of hypertension and are historically undertreated . Thus , we believe that recommending less aggressive targets in this or other high-risk population s requires stronger justification than the guideline cites . Three recent guidelines from other countries have concluded that the appropriate cut point for an age-related differential SBP goal is 80 years or older ( 57 ) . We agree that this higher treatment target in frail hypertensive patients aged 80 years or older better reflects existing evidence . Safety and Adverse Event Risk in Hypertensive Patients Aged 60 Years or Older Despite the limited number of end points in JATOS and the VALISH trial , their size and duration provide evidence of safety of the SBP target of less than 140 mm Hg . The VALISH investigators concluded that this target was safe in relatively healthy patients aged 70 years or older with isolated systolic hypertension ( 18 ) . In JATOS , adverse events requiring treatment discontinuation were reported in only 36 patients , with no differences in discontinuation rate between groups ( 17 ) . This evidence and the favorable results at slightly higher blood pressures in the SHEP trial and HYVET provide reassurance of the safety of an SBP goal of less than 140 mm Hg in older , nonfrail persons . Other Trial Evidence of Benefit of Treatment at an SBP of 140 mm Hg or Lower Results of the SPS3 ( Secondary Prevention of Small Subcortical Strokes ) trial indicated that an SBP target of less than 130 mm Hg versus 144 mm Hg in 3020 patients ( mean age , 63 years ) reduced subsequent strokes by 19 % ( P= 0.08 ) and hemorrhagic strokes by nearly 50 % ( P < 0.01 ) ( 20 ) . Of note , the FEVER trial reported a 44 % ( P < 0.001 ) reduction in all strokes in a subgroup analysis of patients older than 65 years ( 17 ) . Finally , 2 meta-analyses Hypertension is the most common condition seen in primary care and leads to myocardial infa rct ion , stroke , renal failure , and death if not detected early and treated appropriately . Patients want to be assured that blood pressure ( BP ) treatment will reduce their disease burden , while clinicians want guidance on hypertension management using the best scientific evidence . This report takes a rigorous , evidence -based approach to recommend treatment thresholds , goals , and medications in the management of hypertension in adults . Evidence was drawn from r and omized controlled trials , which represent the gold st and ard for determining efficacy and effectiveness . Evidence quality and recommendations were grade d based on their effect on important outcomes . There is strong evidence to support treating hypertensive persons aged 60 years or older to a  BP goal  of less than 150/90 mm Hg and hypertensive persons 30 through 59 years of age to a diastolic goal of less than 90 mm Hg ; however , there is insufficient evidence in hypertensive persons younger than 60 years for a systolic goal , or in those younger than 30 years for a diastolic goal , so the panel recommends a BP of less than 140/90 mm Hg for those groups based on expert opinion . The same thresholds and goals are recommended for hypertensive adults with diabetes or nondiabetic chronic kidney disease ( CKD ) as for the general hypertensive population younger than 60 years . There is moderate evidence to support initiating drug treatment with an angiotensin-converting enzyme inhibitor , angiotensin receptor blocker , calcium channel blocker , or thiazide-type diuretic in the nonblack hypertensive population , including those with diabetes . In the black hypertensive population , including those with diabetes , a calcium channel blocker or thiazide-type diuretic is recommended as initial therapy . There is moderate evidence to support initial or add-on antihypertensive therapy with an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker in persons with CKD to improve kidney outcomes . Although this guideline provides evidence -based recommendations for the management of high BP and should meet the clinical needs of most patients , these recommendations are not a substitute for clinical judgment , and decisions about care must carefully consider and incorporate the clinical characteristics and circumstances of each individual patient Abstract : The 2014 Evidence -Based Guideline for the Management of  High Blood Pressure in Adults Report From the Panel Members Appointed to the Eighth Joint National Committee ( JNC 8) was recently published . This guideline recommended that older adults ( ≥60 years ) without diabetes or chronic kidney disease with systolic blood pressure ( SBP ) ≥150 mm Hg or diastolic blood pressure ( DBP ) ≥90 mm Hg be initiated on antihypertensive medication with a treatment goal SBP/DBP < 150/90 mm Hg . In contrast , the previous 3 JNC guidelines recommended treatment for these individuals be initiated at SBP/DBP ≥140/90 mm Hg with goal SBP/DBP < 140/90 mm Hg . In this article , we review r and omized trials of antihypertensive medication and observational data on SBP and DBP with cardiovascular outcomes among older adults , possible explanations underlying the different findings from these r and omized trials and observational studies , and contemporary antihypertensive treatment patterns among older U.S. adults . In closing , we highlight future research needs related to hypertension and outcomes among older adults The Systolic Blood Pressure Intervention Trial ( SPRINT ) is a large National Institutes of Health– sponsored multicenter r and omized controlled trial that enrolled 9361 patients with a systolic blood pressure ( SBP ) of at least 130 mm Hg . The primary goal of SPRINT was to test whether reducing SBP to a lower goal ( < 120 mm Hg ) than currently recommended ( < 140 mm Hg ) would reduce the occurrence of cardiovascular disease ( CVD ) and chronic kidney disease ( CKD ) events . Enrolled patients were 50 years or older with an SBP ≥130 mm Hg and at least one of the following : a history of CVD , stage 3 CKD ( estimated glomerular filtration rate 20–59 mL/min/1.73 m ) , an intermediate to high risk for CVD other than stroke , or age 75 years or older . A patient was defined as having CVD if they had a prior myocardial infa rct ion , percutaneous coronary intervention , coronary artery bypass grafting , carotid endarterectomy or carotid stenting , peripheral arterial disease with revascularization , acute coronary syndrome , abdominal aortic aneurysm ≥5 cm with or without repair , a coronary calcium score > 400 , or left ventricular hypertrophy . Patients were defined as at intermediate or high risk for CVD based on the following : Framingham Risk Score for 10-year CVD risk of 15 % based on laboratory work performed for lipids within the past 12 months . The primary outcome was a composite of cardiovascular events . The SPRINT study was terminated early after 3.26 years on advisory of the data safety monitoring board . The results of the SPRINT study showed a 25 % reduction in the primary combined cardiovascular outcome and a 27 % reduction in mortality in the group r and omized to SBP < 120 mm Hg . This obviously has important implication s for blood pressure ( BP ) guidelines in this population . The baseline mean systolic and diastolic BPs were 139.7 mm Hg and 78.1 mm Hg , respectively . At 1 year , the mean SBP was 121.4 mm Hg in the intensive treatment group and 136.2 mm Hg in the st and ard treatment group . The SPRINT study included 28 % of patients with CKD , 28 % of patients were older than 75 years , 36 % were women , and 20 % had prior CVD . The sample was diverse and included 29.9 % black , 10.5 % Hispanic , and 57.7 % white patients .  Importantly , SPRINT excluded many patients with hypertension . Who were these population s ? The following groups of patients with hypertension were excluded : those with a history of prior stroke , diabetes , polycystic kidney disease , any secondary cause for hypertension , glomerular filtration rate ( GFR ) < 20 cc/ min , > 1 g of proteinuria per 24 hours , glomerulonephritis treated with immunosuppressive therapy , symptomatic heart failure within the past 6 months or left ventricular ejection fraction < 35 % , expected survival less than 3 years , cancer diagnosed within the past 2 years , organ transplant , cardiovascular event , procedure or hospitalization for unstable angina within the past 3 months , and all patients younger than 50 years . Why were these patients excluded ? Patients with diabetes were excluded as it was felt that this population had already been studied in the Action to Control Cardiovascular Risk in Diabetes ( ACCORD ) BP trial , which did not show a cardiovascular advantage of lower SBP ( < 120 mm Hg ) vs st and ard BP ( < 140 mm Hg ) although there was a decreased risk of stroke .  Patients with polycystic kidney disease have also been studied separately in the HALT Progression of Polycystic Kidney Disease study , which recently showed that rigorous BP control was associated with a slower increase in total kidney volume , no overall change in the estimated GFR , a greater decline in the left ventricular mass index , and greater reduction in urinary albumin excretion .  Patients with excessive proteinuria > 1 g per 24 hours were also excluded , but , based on data from the Modification of Diet in Renal Disease ( MDRD ) , the Blood Pressure Control for Renoprotection in Patients With Nondiabetic Chronic Renal Disease ( REIN ) , and the African American Study of Kidney Disease and Hypertension ( AASK ) studies , lower BP goals ( < 130/80 mm Hg ) have been suggested and recommended by some guidelines in this patient population . Renal transplant recipients were excluded in this population . There are no r and omized controlled trials examining optimal levels of BP and this is a population that needs to be studied . BP threshold for treatment of kidney transplant recipients remains at 130/80 mm Hg , regardless of proteinuria . The Secondary Prevention of Small Subcortical Strokes ( SPS3 ) trial , which compared an SBP treatment target of < 130 mm Hg with a target of 130 mm Hg to 149 mm Hg in participants with a recent lacunar stroke , showed a nonsignificant reduction in recurrent stroke in the group r and omized to the lower target . There are no specific studies that have evaluated BP targets in patients without other comorbidities who are Address for correspondence : Debbie L. Cohen , MD , Renal , Electrolyte and Hypertension Division , Perelman School of Medicine at the University of Pennsylvania , 1 Founders Building , 3400 Spruce Street , Philadelphia , PA 19104 E-mail : Diabetes mellitus is a leading cause of death in the United States and is associated with microvascular and macrovascular complications . Approximately 29.1 million persons , or 9.3 % of the U.S. population , have type 2 diabetes ( 1 ) . In 2012 , the total direct and indirect costs associated with diabetes in the United States were $ 245 billion ( 1 ) . Markedly elevated glucose levels can result in subacute symptoms , such as polyuria , polydipsia , weight loss , and dehydration . Over time , the metabolic derangements associated with diabetes may lead to vision loss , painful neuropathy or sensory loss , foot ulcers , amputations , myocardial infa rct ions , strokes , and end-stage renal disease . Lowering blood glucose may decrease risk for complications , but lowering strategies come with harms , patient burden , and costs . Blood glucose can be measured in various ways , including the hemoglobin A1c ( HbA1c ; also called glycosylated or glycated hemoglobin ) level , which approximates average blood glucose control over about 3 months . As with all laboratory tests , HbA1c measurements are associated with variability ( 2 ) and can vary further with race and ethnicity ( 35 ) . Guidelines have historically recommended initiation or intensification of pharmacologic therapy to achieve specific HbA1c targets , depending on the population in question . The ideal target that optimally balances benefits and harms remains uncertain . Guidance Statement Focus and Target Population The purpose of this American College of Physicians ( ACP ) guidance statement is to critically review the available guidelines from various organizations and the evidence included therein to assist clinicians in making decisions about targets when using pharmacologic therapy in adults with type 2 diabetes . Recent data suggesting that newer agents reduce cardiovascular morbidity and mortality in high-risk patients with type 2 diabetes have prompted calls for a fundamental shift in diabetes management . Some anticipate that treatment decisions will eventually be based more on cardiovascular risk than achievement of specific HbA1c targets , analogous to recent changes in lipid management . However , for the foreseeable future , glycemic targets will continue to influence management decisions by front-line clinicians ( 6 ) . This statement focuses on the benefits and harms of targeting lower versus higher HbA1c levels and does not cover use of specific medications outside of their use to achieve HbA1c targets . The intended audience is all clinicians , and the target population is nonpregnant adults with type 2 diabetes . Methods The Clinical Guidelines Committee ( CGC ) of ACP develops guidance statements on topics where several conflicting guidelines are available . We provide clinicians with a rigorous review of the guidelines and the evidence they include . We then adopt the clinical recommendations if we agree with their evaluation of benefits and harms or adapt them if changes are needed based on our assessment of the recommendations and evidence . Data Sources and Guideline Selection We search ed the National Guideline Clearinghouse and the Guidelines International Network library ( May 2017 ) for guidelines on recommended HbA1c targets in the treatment of type 2 diabetes in nonpregnant outpatient adults . We included guidelines that were developed by national organizations , were published in English , and targeted the correct population . We review ed titles and abstract s and excluded guidelines that were modified or adapted from other organizations or addressed specific population s ( such as pregnant women or patients with kidney disease ) . Our search yielded guidelines from the National Institute for Health and Care Excellence ( NICE ) ( 7 ) and the Institute for Clinical Systems Improvement ( ICSI ) ( 8) . On the basis of the knowledge and expertise of ACP CGC members , we also selected the following 4 guidelines not identified in either data base at the time of the search but commonly used in clinical practice : the American Association of Clinical Endocrinologists and American College of Endocrinology ( AACE/ACE ) guideline ( 9 ) , the American Diabetes Association ( ADA ) guideline ( 10 ) , the Scottish Intercollegiate Guidelines Network ( SIGN ) guideline ( 11 ) , and the U.S. Department of Veterans Affairs and Department of Defense ( VA/DoD ) guideline ( 12 ) . Quality Assessment Six co authors independently review ed and assessed each guideline using the AGREE II ( Appraisal of Guidelines for Research and Evaluation II ) instrument ( 13 ) . This instrument asks 23 questions in the following 6 domains : scope and purpose , stakeholder involvement , rigor of development , clarity of presentation , applicability , and editorial independence . The authors scored each guideline independently , and the scores were compared ( Appendix Figure and Appendix Table 1 ) . Authors then provided a summary determination of whether they would recommend this guideline for use by recording yes , no , or yes with modifications . Appendix Figure . Mean AGREE II scores for items in each domain across the 6 review ers . Each question was rated on a Likert scale with a minimum of 1 point and a maximum of 7 points . The scores were averaged for each of the 6 review ers . Error bars represent calculated st and ard deviation .

Appendix Table 1 . Scaled AGREE II Domain Scores for Each Guideline and Overall Assessment Peer Review The draft guidance statement was peer- review ed through Annals of Internal Medicine and was posted online for comments from ACP Regents and Governors , who represent ACP members at the regional level . The final guidance statement incorporated comments from peer review ers and ACP Regents and Governors . Public Panel Review The development of this guidance statement also included perspectives , values , and preferences of 2 CGC members who represent the public and a 7-member public panel . Summary of Evaluated Guidelines Using the AGREE II Instrument We review ed and rated 6 guidelines ( AACE/ACE [ 9 ] , ADA [ 10 ] , ICSI [ 8 ] , NICE [ 7 ] , SIGN [ 11 ] , and VA/DoD [ 12 ] ) , focusing solely on sections addressing HbA1c targets in patients with type 2 diabetes . Appendix Table 1 shows the detailed scaled domain scores and average quality ratings for each guideline , and the Appendix Figure shows average AGREE II scores for each item in each of the 6 domains . The fundamental difference between high- and low-scoring guidelines was methodology . The 2 lowest-scoring guidelines , AACE/ACE and ADA , scored lowest on stakeholder involvement , applicability , editorial independence , and scientific rigor . A systematic review is the backbone for any trustworthy guideline , but some guidelines might not be based on a systematic review or may not have made the review publicly available ( 14 , 15 ) . Several factors were important in considering guideline quality . For example , although many guidelines described benefits , adverse effects , and the strength and limitations of evidence or linked the evidence to the recommendation , they often inadequately described how they had considered or weighted these factors in developing the final recommendations . The guidelines frequently relied on selective reporting of studies or outcomes and focused on relative versus absolute effects and asymptomatic surrogate measures rather than patient-centered health outcomes . All of the review ed guidelines recommend individualizing HbA1c targets on the basis of patient characteristics , such as comorbid conditions and risk for hypoglycemia ( Appendix ) . The ADA and SIGN guidelines recommend a target of 7 % for the general population , whereas AACE/ACE recommends 6.5 % ( if it can be achieved safely ) . The NICE guideline specifies 6.5 % or 7 % , depending on the patient 's treatment regimen . Both ICSI and VA/DoD recommend target ranges . The ICSI guideline recommends less than 7 % to less than 8 % based on patient factors , whereas the VA/DoD recommends the following target ranges based on life expectancy and comorbid conditions : 6 % to 7 % for patients with a life expectancy greater than 10 to 15 years and no or mild microvascular complications ; 7 % to 8.5 % for those with established microvascular or macrovascular disease , comorbid conditions , or a life expectancy of 5 to 10 years ; and 8 % to 9 % for those with a life expectancy less than 5 years , significant comorbid conditions , advanced complications of diabetes , or difficulties in self-management attributable to mental status , disability , or other factors ( 12 ) . All guidelines recognize that HbA1c targets can be higher in patients with comorbid conditions and limited life expectancy . We looked into the evidence presented in these guidelines , specifically 5 large , long-term r and omized trials with a treat-to-target strategy and corresponding reports on extended follow-up ( 1623 ) . We summarize below the individual studies and result ing benefits and harms . Note that recent studies evaluating the effectiveness and safety of several newer diabetes drugs ( for example , recently approved sodiumglucose cotransporter-2 inhibitors , dipeptidyl peptidase-4 inhibitors , and glucagon-like peptide-1 receptor agonists ) were not considered in guideline sections pertaining to HbA1c targets because these studies were not design ed to evaluate treat-to-target strategies . Therefore , their findings are not described here . Benefits and Harms of Lower HbA1c Targets : Evidence From Clinical Trials Five large , long-term r and omized controlled trials investigated intensive ( achieved HbA1c levels , 6.3 % to 7.4 % ) versus less intensive ( achieved HbA1c levels , 7.3 % to 8.4 % ) Background : Although the prevalence of hypertension ( HTN ) continues to increase in developing countries , including China , recent data are lacking . A nationwide survey was conducted from October 2012 to December 2015 to assess the prevalence of HTN in China . Methods : A stratified multistage r and om sampling method was used to obtain a nationally representative sample of 451 755 residents ≥18 years of age from 31 provinces in mainl and China from October 2012 to December 2015 .  Blood pressure ( BP ) was measured after resting for 5 minutes by trained staff using a vali date d oscillometric BP monitor .  HTN was defined as systolic BP ( SBP ) ≥140 mm Hg/or diastolic BP ( DBP ) ≥90 mm Hg or use of antihypertensive medication within 2 weeks . Pre-HTN was defined as SBP 120 to 139 mm Hg and DBP 80 to 89 mm Hg without antihypertensive medication  . HTN control was defined as SBP < 140 mm Hg and DBP<90 mm Hg . In addition , the prevalence of HTN ( SBP ≥130 or DBP ≥80 mm Hg ) and control rate ( SBP < 130 and DBP < 80 mm Hg ) of HTN were also estimated according to the 2017 American College of Cardiology/American Heart Association High Blood Pressure Guideline . Results : Overall , 23.2 % ( ≈244.5 million ) of the Chinese adult population ≥18 years of age had HTN , and another 41.3 % ( ≈435.3 million ) had pre-HTN according to the Chinese guideline . There were no significant differences of HTN prevalence between urban and rural residents ( 23.4 % versus 23.1 % , P=0.819 ) . Among individuals with HTN , 46.9 % were aware of their condition , 40.7 % were taking prescribed antihypertensive medications , and 15.3 % had controlled HTN . Calcium channel blockers were the most commonly used antihypertensive medication ( 46.5 % ) as monotherapy , and 31.7 % of treated hypertensive patients used ≥2 medications . The prevalence of HTN based on the 2017 American College of Cardiology/American Heart Association guideline was twice as high as that based on 2010 Chinese guideline ( 46.4 % ) , whereas the control rate fell to 3.0 % . Conclusions : In China , there is a high prevalence of HTN and pre-HTN , and awareness , treatment , and control of HTN were low . Management of medical therapy for HTN needs to improve It has been almost 5 years since the publication of the 2010 hypertension guidelines of the Taiwan Society of Cardiology ( TSOC ) . There is new evidence regarding the management of hypertension , including r and omized controlled trials , non-r and omized trials , post-hoc analyses , subgroup analyses , retrospective studies , cohort studies , and registries . More recently , the European Society of Hypertension ( ESH ) and the European Society of Cardiology ( ESC ) published joint hypertension guidelines in 2013 . The panel members who were appointed to the Eighth Joint National Committee ( JNC ) also published the 2014 JNC report . Blood pressure ( BP ) targets have been changed ; in particular , such targets have been loosened in high risk patients . The Executive Board members of TSOC and the Taiwan Hypertension Society ( THS ) aim ed to review up date d information about the management of hypertension to publish an up date d hypertension guideline in Taiwan . We recognized that hypertension is the most important risk factor for global disease burden . Management of hypertension is especially important in Asia where the prevalence rate grows faster than other parts of the world . In most countries in East Asia , stroke surpassed coronary heart disease ( CHD ) in causing premature death . A diagnostic algorithm was proposed , emphasizing the importance of home BP monitoring  and ambulatory BP monitoring  for better detection of night time hypertension , early morning hypertension , white-coat hypertension , and masked hypertension . We disagreed with the ESH/ESH joint hypertension guidelines suggestion to loosen BP targets to < 140/90 mmHg for all patients . We strongly disagree with the suggestion by the 2014 JNC report to raise the BP target to < 150/90 mmHg for patients between 60 - 80 years of age . For patients with diabetes , CHD , chronic kidney disease who have proteinuria , and those who are receiving antithrombotic therapy for stroke prevention , we propose BP targets of < 130/80 mmHg in our guidelines . BP targets are < 140/90 mmHg for all other patient groups , except for patients ≥80 years of age in whom a BP target of < 150/90 mmHg would be optimal . For the management of hypertension , we proposed a treatment algorithm , starting with life style modification ( LSM ) including S-ABCDE ( Sodium restriction , Alcohol limitation , Body weight reduction , Cigarette smoke cessation , Diet adaptation , and Exercise adoption ) . We emphasized a low-salt strategy instead of a no-salt strategy , and that excessively aggressive sodium restriction to < 2.0 gram/day may be harmful . When drug therapy is considered , a strategy called " PROCEED " was suggested ( Previous experience , Risk factors , Organ damage , Contraindications or unfavorable conditions , Expert 's or doctor 's judgment , Expenses or cost , and Delivery and compliance issue ) . To predict drug effects in lowering BP , we proposed the " Rule of 10 " and " Rule of 5 " . With a st and ard dose of any one of the 5 major classes of anti-hypertensive agents , one can anticipate approximately a 10-mmHg decrease in systolic BP ( SBP ) ( Rule of 10 ) and a 5-mmHg decrease in diastolic BP ( DBP ) ( Rule of 5 ) . When doses of the same drug are doubled , there is only a 2-mmHg incremental decrease in SBP and a 1-mmHg incremental decrease in DBP . Preferably , when 2 drugs with different mechanisms are to be taken together , the decrease in BP is the sum of the decrease of the individual agents ( approximately 20 mmHg in SBP and 10 mmHg in DBP ) . Early combination therapy , especially single-pill combination ( SPC ) , is recommended . When patient 's initial treatment can not get BP to targeted goals , we have proposed an adjustment algorithm , " AT GOALs " ( Adherence , Timing of administration , Greater doses , Other classes of drugs , Alternative combination or SPC , and LSM + Laboratory tests ) . Treatment of hypertension in special conditions , including treatment of resistant hypertension , hypertension in women , and perioperative management of hypertension , were also mentioned . The TSOC/THS hypertension guidelines provide the most up date d information available in the management of hypertension . The guidelines are not m and atory , and members of the task force fully realize that treatment of hypertension should be individualized to address each patient 's circumstances . Ultimately , the decision of the physician decision remains of the utmost importance in hypertension management BACKGROUND Among the 60 million Americans with hypertension , only approximately 31 % have their blood pressure ( BP ) under control ( < 140/90 mm Hg ) . Despite the damaging impact of hypertension and the availability of evidence -based target values for BP , interventions to improve BP control have had limited success . OBJECTIVES A r and omized controlled health services intervention trial with a split-plot design is being conducted to improve BP control . This 4-year trial evaluates both a patient and a provider intervention in a primary care setting among diagnosed hypertensive veterans . METHODS In a cluster-r and omization , 30 primary care providers in the Durham VAMC Primary Care Clinic were r and omly assigned to receive the provider intervention or control . The provider intervention is a patient-specific electronically generated hypertension decision support system ( DSS ) delivering guideline -based recommendations to the provider at each patient 's visit , design ed to improve guideline -concordant therapy . For these providers , a sample of their hypertensive patients ( n=588 ) was r and omly assigned to receive a telephone-administered patient intervention or usual care . The patient intervention incorporates patients ' need assessment s and involves tailored behavioral and education modules to promote medication adherence and improve specific health behaviors .  All modules are delivered over the telephone bi-monthly for 24 months . In this trial , the primary outcome is the proportion of patients who achieve a BP < or = 140/90 mm Hg at each outpatient clinic visit over 24 months . CONCLUSION Despite the known risk of poor BP control , a majority of adults still do not have their BP controlled . This study is an important step in testing the effectiveness of a patient and provider intervention to improve BP control among veterans in the primary care setting BACKGROUND We compared blood pressure ( BP ) control in a recent cohort of hypertensive military veterans with BP control in a previous cohort and examined whether hypertension treatment practice s , as defined by the frequency of antihypertensive medication dosage increases , have changed over time . METHODS We abstract ed 1999 outpatient chart data including visit type , BP measurements , comorbidities , and medication use for 981 r and omly selected hypertensive veterans . We examined overall BP control and control in subgroups with diabetes mellitus and renal disease , and compared results with those of a sample of 800 veterans studied from 1990 to 1995 . We also compared the frequency of antihypertensive medication dosage increases in the 2 sample s. RESULTS Mean BPs were significantly lower in 1999 . The mean systolic drop was 3.1 mm Hg and reached 13.7 mm Hg for the subgroups with diabetes and renal disease . Even larger decreases were seen in mean diastolic BPs . In 1999 , 57 % of patients had BP measurements of 140/90 mm Hg or higher , vs 69 % of patients in the 1990 - 1995 study ( P<.001 ) . In 1999 , the BP control of patients with diabetes was similar to that of patients without diabetes , as 60 % of the former had BP measurements of 140/90 mm Hg or higher . Patients with renal disease had better control than those without , however , as only 43 % had BP measurements of 140/90 mm Hg or higher . When comparing sample s , patients with diabetes , renal disease , or both had better BP control in 1999 than their counterparts in the 1990 - 1995 study ( P<.003 in all cases ) . In 1999 , more medical visits were associated with medication dosage increases than in the 1990 - 1995 study . CONCLUSIONS Although overall BP control has improved , BP measurements still exceeded recommended levels in most patients . For patients with diabetes and renal disease  BP was much better controlled in the more recent sample . However , BP control of patients with diabetes was similar to that of patients without diabetes , and not in agreement with the guideline -recommended tighter control . Thus , room for improvement remains , especially in this subgroup Context Physician education and community-based interventions to educate people with hypertension may improve hypertension care in re source -poor setting s. Contribution Among 1341 patients living in 12 communities in Pakistan that were r and omly assigned to general practitioner education , home health visits by trained lay workers , both , or neither , patients in communities assigned to both interventions had the greatest improvements in systolic blood pressure ( 10.8 mm Hg ) after 2 years . Improvements were similar in all other groups ( about 5 mm Hg ) . Caution Twenty-two percent of patients were lost to follow-up . Implication Home visits by trained lay workers plus physician education deserves further study as a way to improve hypertension control in re source -poor setting s. The Editors Cardiovascular disease has , in just a few decades , become the leading cause of death in adults worldwide , accounting for 1 in 5 deaths . Hypertension confers the highest attributable risk for death and disease associated with cardiovascular disease ( 1 , 2 ) . Despite the demonstrated benefits of effective drug treatment ( 3 , 4 ) and the existence of many clinical practice guidelines ( 5 ) , hypertension prevention , treatment , and control rates remain suboptimal worldwide ( 6 ) . The situation is particularly acute in developing countries , such as Pakistan , India , and China , where hypertension has reached epidemic proportionsaffecting more than 20 % of the adult population (7)yet control rates are less than 6 % ( 8) . Poor health literacy and unhealthy lifestyles , compounded by lack of awareness of hypertension ( 7 ) , are part of the cause . In addition , the health systems in these countries are often dysfunctional : More than 80 % of the expenditure for chronic disease care is out-of-pocket ; private care general practitioners ( GPs ) , who primarily treat acute conditions , are the front-line service providers ; and national programs for preventing and controlling hypertension are inadequate . Serious deficiencies in management of hypertension also have been identified in the knowledge and practice of health care providers . ( 9 ) However , evidence for public health interventions to improve hypertension control rates through patient or physician education in Indo-Asian countries is lacking . We conducted the COBRA-1 ( Control of Blood Pressure and Risk Attenuation-1 ) trial in Karachi , Pakistan , to test the effectiveness of 2 community-based strategies : family-based home health education ( HHE ) , delivered by trained community health workers , to improve population -level health literacy and behaviors , and hypertension management training for GPs . We tested the effect of these interventions , alone and in combination , on blood pressure in adults with hypertension . We hypothesized that HHE would be more effective than no education , that the specially trained GPs would provide more effective care than that usually received in Karachi , and that the combined interventions would provide additional benefit . Methods Study Design and Setting We performed a cluster r and omized , controlled trial with a 22 factorial design to determine the effect of  family-based HHE and special training for GPs  on blood pressure in adults 40 years or older with hypertension . We used a cluster approach because our objective was to assess the effectiveness of both HHE and GP training as health system interventions at a population level , and an individual approach would be prone to contamination of interventions and biased outcomes ( 10 ) . The Aga Khan University Ethics Review Committee granted ethical approval . The sampling frame is described elsewhere ( 11 ) . In brief , we used a multistage r and om sampling technique to select 12 of 4200 low- to middle-income , geographic census-based clusters ( mean household monthly income , $ 70 ; about 250 households in each cluster ) in Karachi , the most populous city in Pakistan ( about 16 million inhabitants ) . We ensured at least a 10-km distance between clusters to minimize the risk for contamination by the intervention . Participants Persons 40 years or older who resided in the 12 clusters and had known hypertension or consistently elevated blood pressure on 2 separate visits ( mean of 2 of past 3 measurements of systolic blood pressure 140 mm Hg or diastolic blood pressure 90 mm Hg ) were eligible for inclusion . We excluded pregnant women , persons who could not give informed consent , and bed-bound persons . R and omization and Intervention We used computer-generated codes to r and omly assign 3 clusters each to the following groups : HHE alone , GP alone , HHE and GP combined , and no intervention . Home Health Education We trained 6 community health workers ( 1 for each cluster ) over 6 weeks in methods for using behavior-changing communication strategies to convey st and ardized health education messages to all households in clusters assigned to receive HHE . The education status of the workers we employed was consistent with the requirements of the government-sponsored Lady Health Workers Programme of Pakistan ( 8 or preferably 10 years of schooling ) ( 12 ) . Salary scales and assigned workload were similarly consistent . The health messages included information on the deleterious effects of hypertension and nonpharmacologic interventions for preventing and controlling hypertension and cardiovascular disease , as well as advice on the importance of engaging in moderate physical activity ; maintaining normal body weight ; reducing salt intake ; consuming a diet rich in fruit , vegetables , and low-fat dairy products ; reducing intake of saturated and total fat ( including suggestions on sample recipes for culturally acceptable and economically feasible food products ) ; and smoking cessation ( Appendix 1 ) . The importance of achieving blood pressure targets and adhering to medication and physician follow-up was emphasized . The first HHE session , lasting 90 minutes , was held at a time when all members of the household could be present . Follow-up reinforcement visits of 30 minutes were made every 3 months . Appendix 1 . Training Manual for Community Health Workers General Practitioner Education We invited all GPs in the 6 study areas assigned to this intervention to receive training , with the aim of training at least two thirds of the GPs in each area . We considered this proportion to be feasible both for future uptake of the strategy and for assessing the effectiveness of training . Training was a 1-day session that focused on st and ard treatment algorithms for the stepped-care management of hypertension , which were based on the seventh report of the Joint National Committee ( 3 ) and the Fourth Working Party of the British Hypertension Society guidelines ( 4 ) and modified for the Indo-Asian population ( Appendix 2 ) . The course included components on nonpharmacologic ( diet , exercise , weight loss , and smoking cessation ) and pharmacologic interventions , prescription of low-cost and appropriate generic drugs , preferential use of single-dose drug regimens , scheduled follow-up visits guided by blood pressure , the stepped-care approach for titrating drugs to achieve target blood pressure , and satisfactory consultation sessions for patients , with explanations of treatment and use of appropriate communication strategies . For managing persons with known hypertension , GPs were advised to review medication and blood pressure ; simplify regimens ; and aim to return to a regimen that was in line , as reasonably as possible , with that recommended for those with newly diagnosed hypertension . The recommended target blood pressure was < 140/90 mm Hg for all patients . Although this diverges from recent guidelines for special subgroups ( such as diabetic persons or those with end-organ damage ) , we reasoned that we needed to keep the intervention , guidelines , and targets simple for both patients and practitioners in a setting where blood pressure control rates are less than 3 % ( 7 ) . The training sessions for GPs used a case-based curriculum and were interactive . We provided a certificate of training at the end of the course . Appendix 2 . Training Manual for General Practitioner All study participants were advised to consult a local GP . If participants in the clusters r and omly assigned to a trained GP group did not already have a preferred GP , we gave them a list of trained GPs in their cluster from which to choose . However , it remained the participant 's choice whether they attended a physician on the list . We did not provide for medications or fee-for-health care services . Participants were blinded to intervention status ( training of GP ) . Neither the patients nor the GPs received reimbursement for participation . Screening and Recruitment All households in each cluster were visited , and we obtained informed consent for screening from all adults 40 years and older , whose blood pressure was then measured 3 times with a calibrated automated device ( Omron HEM-737 IntelliSense ; Omron Healthcare , Vernon Hills , Illinois ) in the sitting position after 5 minutes of rest . Those with known hypertension were invited to participate . Those with elevated blood pressure who were not receiving antihypertensive medication were visited again for remeasurement of blood pressure 1 to 4 weeks after the initial visit . If mean blood pressure remained elevated , these persons were also invited to participate . A routine physical examination was performed , and the following information was collected : smoking status , food frequency , and physical activity by question naire , the latter by using the international physical activity question naire ; blood pressure , measured as described above ; anthropometric characteristics ( height , weight , and waist and hip circumferences ) ; and fasting blood glucose level ( Synchron Cx-7/Delta , Beckman Coulter , Fullerton , California ) and lipid profile ( Hitachi-912 , Roche , Basel , Switzerl and ) ( 11 ) . Follow-up Procedures Trained outcomes assessors ( who were not part of and had no relationship with the community health worker team ) evaluated AIMS Major guidelines recommend lowering systolic blood pressure ( SBP ) to < 140 mmHg in all hypertensives , but evidence is missing whether this is beneficial in ( i ) uncomplicated hypertensives , ( ii ) grade 1 hypertensives , and ( iii ) elderly hypertensives . Providing this missing evidence is important to justify efforts and costs of aggressive therapy in all hypertensives . METHODS AND RESULTS Felodipine Event Reduction ( FEVER ) was a double-blind , r and omized trial on 9711 Chinese hypertensives , in whom cardiovascular outcomes  were significantly reduced by more intense therapy ( low-dose hydrochlorothiazide and low-dose felodipine ) achieving a mean of 138 mmHg SBP compared with less-intense therapy ( low-dose hydrochlorothiazide and placebo ) achieving a mean of 142 mmHg . FEVER included older and younger patients , and patients with and without diabetes or cardiovascular disease . In the analyses here reported , Cox regression models assessed outcome differences between more and less-intense treatments in groups of patients with different baseline characteristics . Significant reductions in stroke were found in uncomplicated hypertensives ( -39 % , P = 0.002 ) , in hypertensives with r and omization SBP < 153 mmHg ( -29 % , P = 0.03 ) , and in elderly hypertensives ( -44 % , P < 0.001 ) , when their SBP was lowered by more intense treatment . Significant reductions ( between -29 and -47 % , P = 0.02 to < 0.001 ) were also found in all cardiovascular events and all deaths . Achieving mean SBP values < 140 mmHg by adding a small dose of a generic drug prevented 2.1 ( uncomplicated hypertensives ) and 5.2 ( elderly ) cardiovascular events every 100 patients treated for 3.3 years . CONCLUSIONS These analyses provide strong support , missing so far , to guidelines recommending goal SBP < 140 mmHg in uncomplicated hypertensives , individuals with moderately elevated BP and elderly hypertensives Blood pressure ( BP ) guidelines that set target BP levels often rely on analyses of achieved BP from hypertension treatment trials . The objective of this article was to compare the results of analyses of achieved BP to intention-to-treat analyses on renal disease progression . Participants ( n=1094 ) in the African-American Study of Kidney Disease and Hypertension Trial were r and omly assigned to  either usual BP goal defined by a mean arterial pressure goal of 102 to 107 mm Hg or lower BP goal defined by a mean arterial pressure goal of ⩽92 mm Hg . Median follow-up was 3.7 years . Primary outcomes were rate of decline in measured glomerular filtration rate and a composite of a decrease in glomerular filtration rate by > 50 % or > 25 mL/min per 1.73 m2 , requirement for dialysis , transplantation , or death . Intention-to-treat analyses showed no evidence of a BP effect on either the rate of decline in glomerular filtration rate or the clinical composite outcome . In contrast , the achieved BP analyses showed that each 10-mm Hg increment in mean follow-up achieved mean arterial pressure was associated with a 0.35 mL/min per 1.73 m2 ( 95 % CI : 0.08 to 0.62 mL/min per 1.73 m2 ; P=0.01 ) faster mean glomerular filtration rate decline and a 17 % ( 95 % CI : 5 % to 32 % ; P=0.006 ) increased risk of the clinical composite outcome . Analyses based on achieved BP lead to markedly different inferences than traditional intention-to-treat analyses , attributed in part to confounding of achieved BP with comorbidities , disease severity , and adherence . Clinicians and policy makers should exercise caution when making treatment recommendations based on analyses relating outcomes to achieved BP Elevated blood pressure ( BP ) is a causal risk factor for cardiovascular disease ( CVD ) . Epidemiological analyses have established the grade d and continuous association between higher BP and CVD . Moreover , r and omized clinical trials among individuals with hypertension have demonstrated , in aggregate , a reduction in CVD events by 20 % , coronary heart disease ( CHD ) by 17 % , stroke by 27 % , and heart failure by 28 % for every 10 mm Hg systolic BP ( SBP ) lowering with medical therapy.1 Therefore , prevention , detection , treatment , and control of elevated BP , and its clinical correlate hypertension , is an important public health priority and a primary target for CVD prevention . Although national health surveys have demonstrated improvements in hypertension awareness and treatment , strategic opportunities to improve the efficiency and efficacy of applying BP-lowering therapy in patients most likely to benefit remain.2 Global CVD risk assessment , using multivariable prediction models that estimate absolute CVD risk from routinely measured clinical variables , has been promulgated in several CVD prevention guidelines for cholesterol management to target the most intensive preventive therapies to those at highest absolute CVD risk.3–5 Hypertension guidelines , however , have instead relied solely on isolated BP thresholds and BP goals to guide treatment initiation and intensity . In this review , we provide a rationale for incorporating global CVD risk assessment in BP treatment decision-making and propose a framework to guide its implementation in future CVD prevention guidelines . Epidemiological analyses have firmly established that CVD is a multifactorial condition and that modest increases of several CVD risk factors can often lead to greater overall risk than a severe elevation of a BACKGROUND Chronic kidney disease ( CKD ) is an increasingly common condition , especially in older adults . CKD manifests differently in older versus younger patients , with a risk of death that far outweighs the risk of CKD progressing to the point that dialysis is required . Current CKD guidelines recommend a blood pressure target < 130/80 mm Hg for all patients with CKD ; however , it is unknown how lower versus higher baseline blood pressures may affect older adults with CKD . STUDY DESIGN Retrospective cohort study . SETTING & PARTICIPANTS Older patients ( aged ≥ 75 years ) with CKD ( estimated glomerular filtration rate < 60 mL/min/1.73 m(2 ) ) in a community-based health maintenance organization . PREDICTOR Baseline systolic blood pressure ( SBP ) < 130 , 130 - 160 ( reference group ) , and > 160 mm Hg . OUTCOMES Participants were followed up for 5 years to examine rates of mortality ( primary outcome ) and cardiovascular disease hospitalizations ( secondary outcome ) . RESULTS At baseline , 3,099 participants ( 38.5 % ) had SBP  < 130 mm Hg , 3,772 ( 46.9 % ) had SBP of 131 - 160 mm Hg , and 1,171 ( 14.6 % ) had SBP > 160 mm Hg . A total of 3,734 ( 46.4 % ) died and 2,881 ( 35.8 % ) were hospitalized . Adjusted HRs for mortality in the groups with SBP < 130 and > 160 mm Hg were 1.22 ( 95 % CI , 1.11 - 1.34 ) and 1.06 ( 95 % CI , 0.93 - 1.22 ) , respectively . Adjusted HRs for cardiovascular hospitalization in these groups were 1.10 ( 95 % CI , 0.99 - 1.23 ) and 1.26 ( 95 % CI , 1.09 - 1.45 ) , respectively . LIMITATIONS Although causality should not be inferred from this retrospective analysis , results from this study can generate hypotheses for future r and omized controlled trials to investigate the relationship between blood pressure and outcomes in older patients with CKD . CONCLUSIONS Our study suggests that lower baseline SBP ( ≤ 130 mm Hg ) may predict poorer outcomes in terms of both mortality and cardiovascular hospitalizations in older adults with CKD . Conversely , higher baseline SBP ( > 160 mm Hg ) may predict increased risk of cardiovascular hospitalizations , but does not predict mortality . Clinical trials are required to test this hypothesis OBJECTIVE To provide up date d , evidence -based recommendations for the prevention and management of hypertension in adults . OPTIONS AND OUTCOMES For lifestyle and pharmacological interventions , evidence was review ed from r and omized controlled trials and systematic review s of trials . Changes in cardiovascular morbidity and mortality were the primary outcomes of interest . However , for lifestyle interventions , blood pressure lowering was accepted as a primary outcome given the lack of long-term morbidity and mortality data in this field . For treatment of patients with kidney disease , the progression of kidney dysfunction was also accepted as a clinical ly relevant primary outcome . EVIDENCE A Cochrane collaboration librarian conducted an independent MEDLINE search from 2005 to August 2006 to up date the 2006 Canadian Hypertension Education Program recommendations . In addition , reference lists were scanned and experts were contacted to identify additional published studies . All relevant articles were review ed and appraised independently by both content and method ological experts using prespecified levels of evidence . RECOMMENDATIONS Dietary lifestyle modifications for prevention of hypertension , in addition to a well-balanced diet , include a dietary sodium intake of less than 100 mmol/day . In hypertensive patients , the dietary sodium intake should be limited to 65 mmol/day to 100 mmol/day . Other lifestyle modifications for both normotensive and hypertensive patients include : performing 30 min to 60 min of aerobic exercise four to seven days per week ; maintaining a healthy body weight ( body mass index of 18.5 kg/m2 to 24.9 kg/m2 ) and waist circumference ( less than 102 cm in men and less than 88 cm in women ) ; limiting alcohol consumption to no more than 14 units per week in men or nine units per week in women ; following a diet reduced in saturated fat and cholesterol , and one that emphasizes fruits , vegetables and low-fat dairy products , dietary and soluble fibre , whole grains and protein from plant sources ; and considering stress management in selected individuals with hypertension . For the pharmacological management of hypertension , treatment thresholds and targets should take into account each individual 's global atherosclerotic risk , target organ damage and any comorbid conditions : blood pressure should be lowered to lower than 140/90 mmHg in all patients and lower than 130/80 mmHg in those with diabetes mellitus or chronic kidney disease . Most patients require more than one agent to achieve these blood pressure targets . In adults without compelling indications for other agents , initial therapy should include thiazide diuretics ; other agents appropriate for first-line therapy for diastolic and /or systolic hypertension include angiotensin-converting enzyme ( ACE ) inhibitors ( except in black patients ) , long-acting calcium channel blockers ( CCBs ) , angiotensin receptor blockers ( ARBs ) or beta-blockers ( in those younger than 60 years of age ) . First-line therapy for isolated systolic hypertension includes long-acting dihydropyridine CCBs or ARBs . Certain comorbid conditions provide compelling indications for first-line use of other agents : in patients with angina , recent myocardial infa rct ion , or heart failure , beta-blockers and ACE inhibitors are recommended as first-line therapy ; in patients with cerebrovascular disease , an ACE inhibitor plus diuretic combination is preferred ; in patients with nondiabetic chronic kidney disease , ACE inhibitors are recommended ; and in patients with diabetes mellitus , ACE inhibitors or ARBs ( or , in patients without albuminuria , thiazides or dihydropyridine CCBs ) are appropriate first-line therapies . All hypertensive patients with dyslipidemia should be treated using the thresholds , targets and agents outlined in the Canadian Cardiovascular Society position statement ( recommendations for the diagnosis and treatment of dyslipidemia and prevention of cardiovascular disease ) . Selected high-risk patients with hypertension who do not achieve thresholds for statin therapy according to the position paper should nonetheless receive statin therapy . Once blood pressure is controlled , acetylsalicylic acid therapy should be considered . VALIDATION All recommendations were grade d according to strength of the evidence and voted on by the 57 members of the Canadian Hypertension Education Program Evidence -Based Recommendations Task Force . All recommendations reported here achieved at least 95 % consensus . These guidelines will continue to be up date d annually Importance Intensive blood pressure ( BP ) control confers a benefit on cardiovascular morbidity and mortality ; whether it affects physical function outcomes is unknown . Objective To examine the effect of intensive BP control on changes in gait speed and mobility status . Design , Setting , and Participants This r and omized , clinical trial included 2636 individuals 75 years or older with hypertension and no history of type 2 diabetes or stroke who participated in the Systolic Blood Pressure Intervention Trial ( SPRINT ) . Data were collected from November 8 , 2010 , to December 1 , 2015 . Analysis was based on intention to treat . Interventions Participants were r and omized to intensive treatment with a systolic BP target of less than 120 mm Hg ( n = 1317 ) vs st and ard treatment with a BP target of less than 140 mm Hg ( n = 1319 ) . Main Outcomes and Measures Gait speed was measured using a 4-m walk test . Self-reported information concerning mobility was obtained from items on the Veterans R AND 12-Item Health Survey and the EQ-5D . Mobility limitation was defined as a gait speed less than 0.6 meters per second ( m/s ) or self-reported limitations in walking and climbing stairs . Results Among the 2629 participants in whom mobility status could be defined ( 996 women [ 37.9 % ] ; 1633 men [ 62.1 % ] ; mean [ SD ] age , 79.9 [ 4.0 ] years ) , median ( interquartile range ) follow-up was 3 ( 2 - 3 ) years . No difference in mean gait speed decline was noted between the intensive- and st and ard-treatment groups ( mean difference , 0.0004 m/s per year ; 95 % CI , −0.005 to 0.005 ; P = .88 ) . No evidence of any treatment group differences in subgroups defined by age , sex , race or ethnicity , baseline systolic BP , chronic kidney disease , or a history of cardiovascular disease were found . A modest interaction was found for the Veterans R AND 12-Item Health Survey Physical Component Summary score , although the effect did not reach statistical significance in either subgroup , with mean differences of 0.004 ( 95 % CI , −0.002 to 0.010 ) m/s per year among those with scores of at least 40 and −0.008 ( 95 % CI , −0.016 to 0.001 ) m/s per year among those with scores less than 40 ( P = .03 for interaction ) . Multistate models allowing for the competing risk of death demonstrated no effect of intensive treatment on transitions to mobility limitation ( hazard ratio , 1.06 ; 95 % CI , 0.92 - 1.22 ) . Conclusions and Relevance Among adults 75 years or older in SPRINT , treating to a systolic BP target of less than 120 mm Hg compared with a target of less than 140 mm Hg had no effect on changes in gait speed and was not associated with changes in mobility limitation . Trial Registration clinical trials.gov Identifier : Atrial fibrillation is the most common type of arrhythmia in adults . It is more common as patients age ; the prevalence is 1 % among those younger than age 60 years and increases to more than 8 % in those older than age 80 years . When data are adjusted for age , men are affected more often than women . Cardiac conditions associated with the development of atrial fibrillation are hypertension , rheumatic mitral valve disease , coronary artery disease , and congestive heart failure . Noncardiac causes include hyperthyroidism , hypoxic pulmonary conditions , surgery , and alcohol intoxication . Patients with atrial fibrillation may have symptoms of hemodynamic compromise , such as irregular palpitations and lightheadedness , or more vague symptoms , such as malaise , but may be asymptomatic . Patients with atrial fibrillation are at increased risk for thromboembolic disease . The purpose of this guideline is to make recommendations on the pharmacologic management of newly detected atrial fibrillation in primary care . The target patient population is adult patients with first-detected atrial fibrillation , defined as the presence of symptoms or electrocardiographic evidence of atrial fibrillation . The American College of Cardiology/American Heart Association has recommended using first-detected atrial fibrillation regardless of whether it is symptomatic or self-limited , recognizing that there can be uncertainty about the duration of the episode and about previous undetected episodes ( 1 ) . This guideline does not apply to patients with postoperative or postmyocardial infa rct ion atrial fibrillation , patients with class IV heart failure , patients already taking antiarrhythmic drugs , or patients with valvular disease . The target physician audience is internists and family physicians dedicated to primary care . This guideline is based on the accompanying background paper by McNamara and colleagues ( 2 ) and on the evidence report Management of New-Onset Atrial Fibrillation ( 3 ) , which was produced by the Johns Hopkins Evidence -based Practice Center under contract to the Agency for Healthcare Research and Quality ( AHRQ ) , Rockville , Maryl and . The American Academy of Family Physicians ( AAFP ) and the American College of Physicians ( ACP ) created this guideline in collaboration . The Joint AAFP/ACP Panel review ed the evidence and developed and grade d the recommendations ( Table 1 ) . The guideline was then approved by both organizations . The guideline makes recommendations in the following areas : rate control versus rhythm control , stroke prevention and anticoagulation , electrical cardioversion versus pharmacologic cardioversion , the role of transesophageal echocardiography in guiding therapy , and maintenance therapy . Table 1 . The Guyatt Approach to Grading Recommendations * Section 1 : Rate Control versus Rhythm Control One of the fundamental questions in the management of atrial fibrillation is whether to attempt cardioversion . The answer to this question depends on whether rate control or rhythm control provides more effective protection from thromboembolic events , improved mortality , better relief of symptoms , or improved quality of life . Another significant clinical question is whether certain population s , such as women , patients with hypertension or congestive heart failure , or young people with structurally healthy hearts , have better outcomes with one or the other strategy . Four studies have compared rate control with rhythm control . The study sample s have generally involved older patients ( > 65 years of age ) , and women and younger patients with healthy hearts and paroxysmal atrial fibrillation have not been well represented ( 5 ) . The Atrial Fibrillation Follow-up Investigation of Rhythm Management ( AFFIRM ) trial compared rhythm control versus rate control , and use of anticoagulation was recommended in both arms ( 6 ) . More than 4000 patients who were at least 65 years of age or who had at least 1 risk factor for stroke or death , such as hypertension , diabetes , previous stroke , or poor ventricular function , were followed for a mean of 3.5 years . Slightly more than one third of the patients were enrolled after their first episode of atrial fibrillation , and more than 90 % had had their qualifying episode within the previous 6 weeks . In more than two thirds of patients , the qualifying episode lasted at least 2 days . The average patient age was 70 years . Sixty-one percent of patients were men , and 89 % were white . Seventy-one percent of patients had hypertension , 38 % had coronary heart disease , 18 % had previously had failure of antiarrhythmic therapy , and 12 % had no apparent heart disease ( lone atrial fibrillation ) . Patients were r and omly assigned to rate or rhythm control , and their physicians chose the specific therapies ( pharmacologic first , then nonpharmacologic if needed ) . Anticoagulation was continued indefinitely in the rate-control group and was encouraged in the rhythm-control group but could be stopped at the physician 's discretion if sinus rhythm had been maintained for at least 4 , and preferably 12 , consecutive weeks with antiarrhythmic therapy . The prevalence of sinus rhythm in the rhythm-control group was 82 % , 73 % , and 63 % at 1 , 3 , and 5 years , respectively . The prevalence of sinus rhythm in the rate-control group was 34.6 % at 5 years . The primary end point in the AFFIRM trial , overall mortality , was not statistically significantly different between the groups . However , the rhythm-control strategy was associated with a higher risk for death than the rate-control strategy among older patients , those without congestive heart failure , and those with coronary disease .  Rates of stroke also did not differ between groups ; 70 % of all strokes occurred in patients who had stopped receiving anticoagulation or who had subtherapeutic international normalized ratios ( < 2.0 ) . More hospitalizations were reported in the rhythm-control group ( P < 0.001 ) . Another recent study , the RAte Control versus Electrical cardioversion for persistent atrial fibrillation ( RACE ) study , r and omly assigned patients to receive aggressive rhythm control or rate control ( 7 ) . This was a smaller study , involving 522 patients ( mean age , 68 years ) . Sixty-four percent of patients were men , 49 % had hypertension , and 27 % had coronary artery disease . All patients had persistent atrial fibrillation lasting less than 1 year and had had at least 1 previous electrical cardioversion ( a maximum of 2 previous cardioversions was permitted for study inclusion ) . The primary end point was a composite of cardiovascular mortality , heart failure , thromboembolic complications , bleeding , pacemaker implantation , and severe side effects of antiarrhythmic drugs . Again , no difference was seen between groups in the primary composite end point . As in the AFFIRM study , most of the strokes occurred in patients whose anticoagulation had been halted or patients whose international normalized ratio was subtherapeutic ( < 2.0 ) . In post hoc analysis , a benefit for rate control over rhythm control was seen in patients with hypertension and in women . Since this was a post hoc analysis , these results will need to be confirmed by further studies . Of note , despite an aggressive treatment protocol , at the end of follow-up only 39 % of the patients in the rhythm-control group were in sinus rhythm . The Pharmacological Intervention in Atrial Fibrillation ( PIAF ) trial r and omly assigned 252 patients 18 to 75 years of age with new-onset or permanent symptomatic atrial fibrillation ( mean duration of atrial fibrillation , approximately 4 months ) to rate control with diltiazem or aggressive conversion ( many times if necessary ) and maintenance therapy with amiodarone ( 8) . The primary end point of the study was improvement in symptoms related to atrial fibrillation . After 1 year of follow-up , relief of symptoms was similar in both groups , as were quality -of-life measures . Walking distance was improved in the rhythm-control group , but hospital admissions were more frequent in this group . Although final results are not yet available , preliminary reports of the Strategies of Treatment of Atrial Fibrillation ( STAF ) trial have been presented ( 9 ) . Patients were r and omly assigned to receive anticoagulation for 3 weeks before conversion and for 4 weeks after attempted conversion , with antiarrhythmic therapy to maintain sinus rhythm , or to long-term anticoagulation and rate control . ( Patients included in this study had at least 1 previous conversion attempt . ) After more than 1.5 years of follow-up , no difference was seen between the groups in rates of the primary end points of death , stroke , transient ischemic attacks , cardiopulmonary resuscitation , or thromboembolism . Of interest , only 40 % of patients in the rhythm-control group were still in sinus rhythm at 1 year , and all primary end points occurred in patients in atrial fibrillation , even in the rhythm-control group . This result has created speculation about whether fewer events would have occurred if anticoagulation had been continued indefinitely in the conversion group . It also suggests that despite aggressive rhythm management , a substantial number of patients can not maintain sinus rhythm . In general , the trial sample s were older and male and had risk factors for stroke , such as hypertension , congestive heart failure , and coronary disease . Certain subgroups of patients with atrial fibrillation , such as younger patients with healthy hearts or paroxysmal atrial fibrillation , were not well represented in the trials . Therefore , it is not certain whether these subgroups of patients may benefit from more aggressive rhythm control or rate control . Recommendation 1 : Rate control with chronic anticoagulation is the recommended strategy for the majority of patients with atrial fibrillation . Rhythm control has not been shown to be superior to rate control ( with chronic anticoagulation ) in reducing morbidity and mortality and may be inferior in some patient subgroups to rate control . Rhythm Background : Available information on the prevalence and management of hypertension in the Canadian population date s back to 1986–1992 and probably does not reflect the current status of this major risk factor for cardiovascular disease . We sought to evaluate the current prevalence and management of hypertension among adults in the province of Ontario . Methods : Potential respondents from r and omly selected dwellings within target neighbourhoods in 16 municipalities were contacted at their homes to request participation in the study . For potential respondents who agreed to participate ,  blood pressure  was measured with an automated device . Estimation weights were used to obtain representative estimates of population parameters . Responses were weighted to the total adult population in Ontario of 7 996 653 . Results : From 6436 eligible dwellings , contact was made with 4559 potential participants , of whom 2992 agreed to participate .  Blood pressure measurements were obtained for 2551 of these respondents ( age 20–79 years ) .  Hypertension , defined as systolic blood pressure of 140 mm Hg or more , diastolic blood pressure of 90 mm Hg or more , or treatment with an antihypertensive medication , was identified in 21.3 % of the population overall ( 23.8 % of men and 19.0 % of women ) . Prevalence increased with age , from 3.4 % among participants 20–39 years of age to 51.6 % among those 60–79 years of age . Hypertension was more common among black people and people of South Asian background than among white people ; hypertension was also associated with higher body mass index . Among participants with hypertension , 65.7 % were undergoing treatment with control of hypertension , 14.7 % were undergoing treatment but the hypertension was not controlled , and 19.5 % were not receiving any treatment ( including 13.7 % who were unaware of their hypertension ) . The extent of control of hypertension did not differ significantly by age , sex , ethnic background or comorbidities . Interpretation : In Ontario , the overall prevalence of hypertension is high in the older population but appears not to have increased in recent decades . Hypertension management has improved markedly among all age groups and for both sexes Diabetes is the leading cause of major complications , such as end-stage renal disease and lower extremity amputations , and is a significant contributor to ischemic heart disease , stroke , peripheral vascular disease , and vision loss ( 1 ) . There has been increasing acceptance of the importance of individualizing glycemic management and assessment of risk for adverse events , especially hypoglycemia ( 26 ) . This is of great importance for all patients , especially older adults ( aged 65 years ) with comorbid conditions . In 2013 , 12.0 million older adults in the United States had diabetes , comprising 40 % of the 30.2 million persons with the disease ( 7 ) . Older adults account for an estimated 60 % to 70 % of the U.S. Department of Veterans Affairs ( VA ) and U.S. Department of Defense ( DoD ) diabetic population ( largely retirees ) ( VA/DoD. Unpublished data ) . These considerations make safe and effective diabetes management a policy priority for health care providers ( physicians , nurses , dietitians , and pharmacists ) and policymakers in both the VA and the DoD. The 2017 VA/DoD Clinical Practice Guideline ( CPG ) for the Management of Type 2 Diabetes Mellitus in Primary Care offers health care providers an evidence -based framework to evaluate , treat , and manage persons with type 2 diabetes  mellitus in the context of their individual needs and preferences ( 8) . The current article is a summary of key CPG recommendations , which was developed with multiple stakeholders to ensure representation by a broad spectrum of clinicians . It provides practice recommendations for the care of patients with diabetes , with an emphasis on shared decision making . Guideline Development and Review Process These recommendations were developed using methods established by the VA/DoD Evidence -Based Practice Work Group ( EBPWG ) ( 9 ) , which are aligned with st and ards for trustworthy guidelines ( 10 ) . The EBPWG and the U.S. Army Medical Comm and selected guideline panel cochairs ( 1 each from the VA and the DoD ) . The cochairs then selected a multidisciplinary panel of practicing clinician stakeholders , including primary care physicians ( family and internal medicine ) , endocrinologists , medical nutritionists , pharmacists , diabetes educators , and nurse practitioners . At the start of the CPG development process and at other key points throughout , all members were required to su bmi t disclosure statements for potential conflicts of interest in the previous 24 months . Verbal affirmations of no conflicts were used during meetings throughout the development process . The project team was also subject to r and om Web-based surveillance ( for example , ProPublica ) . The VA/DoD contracted with The Lewin Group , a third party with expertise in clinical practice guideline development , to facilitate meetings . The guideline panel , in collaboration with the ECRI Institute , developed 9 key questions using the PICOTS ( population , intervention , comparator , outcomes , timing of outcomes measurement , and setting ) format . A systematic search of the peer- review ed literature from January 2009 through March 2016 was conducted to find evidence relevant to the key questions that focused on r and omized trials , systematic review s , and meta-analyses of fair or better quality . One key question was up date d through 14 June 2016 . The search methods and results are detailed in the full guideline ( 8) . The guideline panel rated recommendations by using the GRADE ( Grading of Recommendations Assessment , Development and Evaluation ) method ( 11 ) . The guideline panel focused on developing new and up date d recommendations using the evidence review for the key questions . The panel also considered , without a complete review of the relevant evidence , the current applicability of recommendations that were included in the 2010 CPG . As part of the development process , a patient focus group was also convened to better underst and the perspectives of patients receiving diabetes treatment in the VA and the DoD. Five patients were included , consistent with the requirements of the federal Paperwork Reduction Act . All patients had type 2 diabetes and were veterans receiving care in the VA . The focus group explored knowledge of treatment options , views on the delivery of care , patients ' needs and preferences , and the effect of diabetes on their lives . Important concepts that emerged from the focus group were shared with the panel and informed guideline development . It was acknowledged that this convenience sample may not be representative of all VA and DoD patients receiving treatment for type 2 diabetes . The draft guideline was sent to more than 15 expert review ers inside and outside the federal sector . Comments were review ed and , where appropriate , were incorporated into the final guideline based on panel consensus . The VA/DoD EBPWG approved the final document on 3 April 2017 and released it on 17 April 2017 . Recommendations are presented in the Table , and an algorithm for establishing a personalized glycemic goal and treatment plan is presented in the Figure . Key recommendations are review ed in this article . Table . Summary of Recommendations From the 2017 VA/DoD CPG on the Management of Type 2 Diabetes Mellitus Figure . Algorithmic approach to evaluating glycemic control risk factors , setting a personalized glycemic control target range , providing self-management ( including lifestyle and nutrition ) education , and initiating or reevaluating medication therapy . Recommendations Provide Patient-Centered Care and Incorporate Shared Decision Making The CPG strongly encourages clinicians to incorporate shared decision making and partner with their patients . Shared decision making is the process by which the patient and family , in conjunction with the care provider , reach an agreement about a plan of care and treatment . Key principles include readiness of the patient and family , tools with underst and able information about the benefits and harms of all options , and strategies to identify and incorporate patient preferences . Patients can not effectively participate in care and shared decision making unless they underst and diabetes and how they can be involved in planning and carrying out the jointly developed care plan . Shared decision making reinforces a trusted therapeutic relationship and increases patient satisfaction and treatment buy-in with regard to the methods used to reach a particular goal or treatment plan ( 1214 ) . It should be used not only for patients with stable glycemic control but also to assist those who are not able or willing to make lifestyle changes and decisions that affect their diabetes at any time during the course of treatment . At a minimum , shared decision making should be included at the time of diagnosis , during difficulties with management , and at times of transition or development of complications ( 14 ) . Benefits include greater knowledge of medications ( 13 ) and underst and ing of risks ( 14 ) . In addition , patient-centered care and shared decision making together may decrease patient anxiety , increase trust in clinicians ( 15 ) , and improve treatment adherence ( 16 ) . Family involvement should be considered if appropriate , especially in older adults ( 17 ) . Patient information should be culturally appropriate ; underst and able and actionable by people with limited literacy skills ; and accessible to those with physical , sensory , or learning needs ( 18 ) . As part of the patient-centered care approach to diabetes management , clinicians should explore with the patient the outcomes of previous opportunities for shared decision making , their ability to self-manage , prior efforts to change health behaviors , past treatment experiences ( including reasons for discontinuing treatment ) , and relevant clinical outcomes . In actively sharing decisions , they should involve the patient in prioritizing problems to be addressed and setting specific goals regardless of the setting or level of care . Assess Patient Characteristics and Nonglycemic Factors When Interpreting Results of Hemoglobin A1c , Fructosamine , and Other Glycemic Biomarker Testing Many factors affect measurement of hemoglobin A1c ( HbA1c ) besides the level of glycemia ( 19 ) . Because HbA1c level depends on the duration of erythrocyte exposure to glucose , conditions that alter erythrocyte life span affect the measured level of HbA1c ( 20 , 21 ) . Iron deficiency anemia , which prolongs erythrocyte life span and exposes the cell to glucose for a longer period , is associated with falsely elevated HbA1c levels ( 22 ) . In contrast , conditions that shorten erythrocyte life span ( such as hemolytic anemia ) may result in falsely low HbA1c levels . Various other conditions , such as chronic kidney disease , may alter HbA1c measurement . Hemoglobin variants can result in falsely elevated or falsely lowered HbA1c levels , depending on the assay used ( 2325 ) . In addition , oral hypoglycemic agents ( metformin or sulfonylureas ) may alter the relationship between blood glucose and HbA1c levels , although the clinical significance is unclear ( 26 ) . There are also racial/ethnic differences in HbA1c levels for a given level of glycemia . A previous study found that African Americans with prediabetes ( 27 ) had HbA1c values that were 0.4 % higher than among white persons ; those who were within 3 years of diagnosis ( 28 ) also had higher HbA1c values than white persons for any measure of glycemia . This difference can not be explained by measured differences in glycemia , clinical factors known to affect HbA1c measurement , or sociodemographic factors ( 27 , 28 ) . Therefore , it is recommended that a new diagnosis of diabetes be based on a confirmatory fasting blood glucose level of at least 7.0 mmol/L ( 126 mg/dL ) if the initial HbA1c value is 6.5 % to 6.9 % . How and where the HbA1c level is measured can also affect results because of intralaboratory variation ( variation in test accuracy and precision ) and interlaboratory variation ( variation related to use of different test methods ) . A single HbA1c measurement , even from a Noncompliance with treatment has long been the plague of the national health-care system . Each year it is estimated that noncompliance with medication costs the UK economy billions of pounds , as a result of preventable hospital admissions and loss of productivity due to illness . In addition , noncompliance has been identified as the predominant reason for the failure of medical therapy and disease progression . Compliance has been defined as ‘ the extent to which a person ’s behaviour coincides with medical care or advice ’ . In the management of hypertension , figures from the United States suggest that noncompliance with medication may be as high as 50–80 % , with compliance decreasing rapidly over time . Based on the current definition of hypertension ( blood pressure ( BP ) of X140/90 mm Hg ) , the 1998 Health Survey for Engl and revealed that 42 % and 33 % of adult ( X16 years ) men and women , respectively , were hypertensive . Fewer than 10 % of all UK hypertensive patients currently achieve the recommended target BP of o140/90 mmHg , despite the well-known risks associated with hypertension and the overwhelming evidence from numerous clinical trials of the benefits of antihypertensive medication . A recent study , based on a meta- analysis of 61 prospect i ve BP studies , calculated that if all hypertensive patients in the UK reduced their systolic BP to o140 mmHg , approximately 21 400 stroke deaths , 41 400 ischaemic heart disease ( IHD ) deaths , and 125 600 events ( nonfatal stroke or IHD ) could be prevented each year . Why then , in the face of such overwhelming evidence of the benefits of BP reduction , are less than one in 10 people in the UK achieving adequate control of their BP ? Various explanations have been proffered to explain why such a large percentage of patients have resistant hypertension , including secondary hypertension and endogenous resistance to treatment . However , the main reason for inadequate control of BP is poor compliance with the treatment regimen , both pharmacological and behavioural ( eg , weight reduction , sodium intake restriction , and exercise ) . Underst and ing the reasons for patient noncompliance with antihypertensive medication is essential if BP is to be more effectively managed . Table 1 presents some possible factors contributing to noncompliance with medication regimens . Much of the earlier research focused on identifying patient characteristics of noncomplaint individuals and the complexity of the medication regimen . BP control typically requires more than one antihypertensive medication and the frequency of dosing may vary . The complexity of the drug regimen effects compliance ; compliance among hypertensive patients improves considerably when drugs are prescribed just once a day . In addition , many patients experience unpleasant side effects from their medication that may be unacceptable in a largely asymptomatic disease . This is often reported as one of the main reasons for nonor partial compliance . However , more recent studies have focused on patient ’s decisions and the complex relationship between the patient and physician as possible mediating factors for compliance . Patients often make rational decisions about the benefits of medication compared to the risks before they decide whether or not to comply with treatment . Several studies , some qualitative , have investigated how hypertensive patients balance these concerns with their reasons for taking such medication . The majority of patients ( 80 % ) also express general concerns about taking medication ; previous bad experiences , perceptions that drugs are unnatural or unsafe and are best avoided , and that drugs signify ill health .

E-mail : deirdre.lane@swbh.nhs.uk Journal of Human Hypertension ( 2004 ) 18 , 595–597 & 2004 Nature Publishing Group All rights reserved 0950 - 9240/04 $ Background — Hypertension treatment guidelines recommend that blood pressure ( BP ) be lowered to < 140/90 mm Hg , but that a reduction to < 130/80 mm Hg be adopted in patients at high cardiovascular ( CV ) risk . We investigated the CV and renal benefits associated with these BP targets in the high-CV-risk population of the Ongoing Telmisartan Alone and in Combination With Ramipril Global End Point Trial ( ONTARGET ) . Methods and Results — Patients were divided into 4 groups according to the proportion of in-treatment visits before the occurrence of an event ( < 25%–>75 % ) in which BP was reduced to < 140/90 or < 130/80 mm Hg . After adjustment for demographic and clinical variables , a progressive increase in the proportion of visits in which BP was reduced to < 140/90 or < 130/80 mm Hg was associated with a progressive reduction in the risk of stroke , new onset of microalbuminuria or macroalbuminuria , and return to normoalbuminuria in albuminuric patients . An increased frequency of BP control to either target did not have any consistent effect on the adjusted risk of myocardial infa rct ion and heart failure . The adjusted risk of CV events was reduced by increasing the frequency of BP control to < 140/90 mm Hg , but not to < 130/80 mm Hg . Similar findings were obtained for the achievement of the BP target in the visit preceding a CV event . Conclusion — The more frequent achievement of the BP targets recommended by guidelines led to cerebrovascular and renal protection , but did not increase cardiac protection . Overall , CV protection was favorably affected by the less tight but not by the tighter BP target . Clinical Trial Registration — URL : http://www . clinical trials.gov . Unique identifier : NCT00153101 BACKGROUND Because of age-related differences in the cause of hypertension , it is uncertain whether current exercise guidelines for reducing blood pressure ( BP ) are applicable to older persons . Few exercise studies in older persons have evaluated BP changes in relation to changes in body composition or fitness . METHODS This was a 6-month r and omized controlled trial of combined aerobic and resistance training ; controls followed usual care physical activity and diet advice .  Participants ( aged 55 - 75 years ) had untreated systolic BP ( SBP ) of 130 to 159 mm Hg or diastolic BP ( DBP ) of 85 to 99 mm Hg . RESULTS Fifty-one exercisers and 53 controls completed the trial . Exercisers significantly improved aerobic and strength fitness , increased lean mass , and reduced general and abdominal obesity . Mean decreases in SBP and DBP , respectively , were 5.3 and 3.7 mm Hg among exercisers and 4.5 and 1.5 mm Hg among controls ( P < .001 for all ) . There were no significant group differences in mean SBP change from baseline ( -0.8 mm Hg ; P=.67 ) . The mean DBP reduction was greater among exercisers ( -2.2 mm Hg ; P=.02 ) . Aortic stiffness , indexed by aortofemoral pulse-wave velocity , was unchanged in both groups . Body composition improvements explained 8 % of the SBP reduction ( P = .006 ) and 17 % of the DBP reduction ( P<.001 ) . CONCLUSIONS A 6-month program of aerobic and resistance training lowered DBP but not SBP in older adults with mild hypertension more than in controls . The concomitant lack of improvement in aortic stiffness in exercisers suggests that older persons may be resistant to exercise-induced reductions in SBP . Body composition improvements were associated with BP reductions and may be a pathway by which exercise training improves cardiovascular health in older men and women The prevalence of hypertension in type 2 diabetics is high , though there is no published data for Switzerl and . This prospect i ve cohort survey determined the frequency of type 2 diabetes mellitus associated with hypertension from medical practitioners in Switzerl and , and collected data on the diagnostic and therapeutic work‐up for cardiovascular risk patients . The Swiss Hypertension And Risk Factor Program ( SHARP ) is a two‐part survey : The first part , I‐SHARP , was a survey among 1040 Swiss physicians to assess what are the target blood pressure ( BP ) values and preferred treatment for their patients . The second part , SHARP , collected data from 20,956 patients treated on any of 5 consecutive days from 188 participating physicians . In I‐SHARP , target BP⩽135/85 mmHg , as recommended by the Swiss Society of Hypertension , was the goal for 25 % of physicians for hypertensives , and for 60 % for hypertensive diabetics ; values > 140/90 mmHg were targeted by 19 % for hypertensives , respectively 9 % for hypertensive diabetics . In SHARP , 30 % of the 20,956 patients enrolled were hypertensive ( as defined by the doctors ) and 10 % were diabetic ( 67 % of whom were also hypertensive ) . Six per cent of known hypertensive patients and 4 % of known hypertensive diabetics did not receive any antihypertensive treatment . Diabetes was not treated pharmacologically in 20 % of diabetics . Proteinuria was not screened for in 45 % of known hypertensives and in 29 % of known hypertensive diabetics . In Switzerl and , most physicians set target BP levels higher than recommended in published guidelines . In this country with easy access to medical care , high medical density and few financial constraints , appropriate detection and treatment for cardiovascular risk factors remain highly problematic
Benefits of Treating Higher Versus Lower BP Targets in Older Adults Across all trials , treating high BP in older adults was beneficial .
This is probably related to the higher frequency of cardiovascular events seen in these patients .
Treatment Effects According to Diastolic BP Evidence was insufficient to determine the benefit of treating diastolic hypertension in the absence of systolic hypertension .
A subgroup analysis of SPRINT showed a nonstatistically significant increase in the rate of serious adverse events , hypotension , syncope , electrolyte abnormalities , or acute
Hypertension , an elevation of systemic arterial blood pressure ( BP ) , is a very common chronic disease in the United States .
The overall prevalence of hypertension among U.S. adults is 29.0 % , and it increases to 64.9 % in adults aged 60 years or older ( 1 ) .
Hypertension was associated with a total of $ 46 billion in health care services , medications , and missed days of work in the United States in 2011 ( 2 ) .
Appropriate management of hypertension reduces the risk for cardiovascular disease , renal disease , cerebrovascular disease , and death ( 36 ) .
However , determining the most appropriate BP targets , particularly for adults aged 60 years or older , has been controversial .
Debate about the goal for systolic BP ( SBP ) among adults treated for hypertension has intensified , especially in light of recent recommendations ( 7 ) .
In addition , when selecting BP targets for adults aged 60 years or older , clinicians need to consider comorbid conditions that could affect treatment choice .
Original Version ( PDF ) Guideline Focus and Target Population The purpose of this American College of Physicians ( ACP ) and American Academy of Family Physicians ( AAFP ) joint guideline is to present evidence -based recommendations on the benefits and harms of higher ( < 150 mm Hg ) versus lower ( 140 mm Hg ) SBP targets for the treatment of hypertension in adults aged 60 years or older .
These recommendations are based on a background evidence review ( 8) and systematic review sponsored by the U.S. Department of Veterans Affairs ( VA ) ( 9 ) .
