Antihypertensive drugs used to treat predominantly healthy adults aged 18 to 59 years with mild to moderate primary hypertension have a small absolute effect to reduce cardiovascular mortality and morbidity primarily due to reduction in cerebrovascular mortality and morbidity .

OBJECTIVES To quantify antihypertensive drug effects on all-cause mortality in adults aged 18 to 59 years with mild to moderate primary hypertension .
To quantify effects on cardiovascular mortality plus morbidity ( including cerebrovascular and coronary heart disease mortality plus morbidity ) , withdrawal due adverse events and estimate magnitude of systolic blood pressure ( SBP ) and diastolic blood pressure ( DBP ) lowering at one year .
Tight blood pressure control and risk of macrovascular and microvascular complications in type 2 diabetes: UKPDS 38
Abstract Objective : To determine whether tight control of blood pressure prevents macrovascular and microvascular complications in patients with type 2 diabetes . Design : R and omised controlled trial comparing tight control of blood pressure aim ing at a blood pressure of < 150/85 mm Hg ( with the use of an angiotensin converting enzyme inhibitor captopril or a β blocker atenolol as main treatment ) with less tight control aim ing at a blood pressure of < 180/105 mm Hg . Setting : 20 hospital based clinics in Engl and , Scotl and , and Northern Irel and . Subjects : 1148 hypertensive patients with type 2 diabetes ( mean age 56 , mean blood pressure at entry 160/94 mm Hg ) ; 758 patients were allocated to tight control of blood pressure  and 390 patients to less tight control  with a median follow up of 8.4 years . Main outcome measures : Predefined clinical end points , fatal and non-fatal , related to diabetes , deaths related to diabetes , and all cause mortality . Surrogate measures of microvascular disease included urinary albumin excretion and retinal photography . Results : Mean blood pressure during follow up was significantly reduced in the group assigned tight blood pressure control ( 144/82 mm Hg ) compared with the group assigned to less tight control ( 154/87 mm Hg ) ( P<0.0001 ) . Reductions in risk in the group assigned to tight control compared with that assigned to less tight control were 24 % in diabetes related end points ( 95 % confidence interval 8 % to 38 % ) ( P=0.0046 ) , 32 % in deaths related to diabetes ( 6 % to 51 % ) ( P=0.019 ) , 44 % in strokes ( 11 % to 65 % ) ( P=0.013 ) , and 37 % in microvascular end points ( 11 % to 56 % ) ( P=0.0092 ) , predominantly owing to a reduced risk of retinal photocoagulation . There was a non-significant reduction in all cause mortality . After nine years of follow up the group assigned to tight blood pressure control also had a 34 % reduction in risk in the proportion of patients with deterioration of retinopathy by two steps ( 99 % confidence interval 11 % to 50 % ) ( P=0.0004 ) and a 47 % reduced risk ( 7 % to 70 % ) ( P=0.004 ) of deterioration in visual acuity by three lines of the early treatment of diabetic retinopathy study ( ETDRS ) chart . After nine years of follow up 29 % of patients in the group assigned to tight control required three or more treatments to lower blood pressure to achieve target blood pressures . Conclusion : Tight blood pressure control in patients with hypertension and type 2 diabetes achieves a clinical ly important reduction in the risk of deaths related to diabetes , complications related to diabetes , progression of diabetic retinopathy , and deterioration in visual acuity
