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 .
All-cause mortality and coronary heart disease were not reduced .
There is lack of good evidence on withdrawal due to adverse events .
BACKGROUND Hypertension is an important risk factor for adverse cardiovascular events including stroke , myocardial infa rct ion , heart failure and renal failure .
The main goal of treatment is to reduce these events .
Systematic review s have shown proven benefit of antihypertensive drug therapy in reducing cardiovascular morbidity and mortality but most of the evidence is in people 60 years of age and older .

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 .
The Hypertension Optimal Treatment (HOT) Study: 12-month data on blood pressure and tolerability. With special reference to age and gender.
The Hypertension Optimal Treatment ( HOT ) Study is an ongoing prospect i ve , r and omized , multicenter trial conducted in 26 countries . Its two main aims are to evaluate the relationship between three levels of target diastolic blood pressure ( < or = 90 , < or = 85 or < or = 80 mmHg ) and the incidence of cardiovascular morbidity and mortality in hypertensive patients and the effects on morbidity and mortality of a low dose , 75 mg daily , of acetylsalicylic acid ( ASA , aspirin ) compared with placebo .  Altogether 19,193 patients have been recruited and r and omized and one-year data are now available for all patients . This is a report on the blood pressures achieved , the tolerability and other available data after 12 months of follow-up of all patients . Special reference will be given to the subgroup of elderly patients ( > or = 65 years , n = 6,113 ) as compared to younger patients ( < 65 years , n = 13,080 ) . On average , the target group < or = 90 mmHg in diastolic blood pressure has reached 86 mmHg , the target group < or = 85 mmHg has reached 83 mmHg and the target group < or = 80 mmHg has reached 81 mmHg . The percentage of patients that has obtained their target blood pressures is 84 % in the target group < or = 90 mmHg , 72 % in the target group < or = 85 mmHg and 57 % in the target group < or = 80 mmHg at 12 months of follow-up . In the elderly subgroup ( > or = 65 years of age ) the percentage of patients at target is higher for all target groups , being 86 , 76 and 61 % , respectively , at 12 months . Antihypertensive treatment is initiated with a calcium antagonist , felodipine , at a dose of 5 mg once daily . If target blood pressure is not reached , additional antihypertensive therapy , with either an angiotensin converting enzyme ( ACE ) inhibitor or a beta-adrenoceptor blocking agent , is given . Further dose adjustments are made in accordance with a set protocol . As a fifth and final step a diuretic may be added . Side effects have been relatively few in this large multinational series of intensively treated hypertensive patients . Only ankle edema , 2.6 % and 3.0 % , and coughing , 1.3 % and 0.8 % , in young and elderly patients , respectively , exceed a frequency of 1 % , and 88 % of all patients are still taking their baseline therapy felodipine after one year . The one-year data presented here indicate that it should be possible to fulfill the primary aims of the HOT Study
