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 .
STOP-Hypertension 2: a prospective intervention trial of "newer" versus "older" treatment alternatives in old patients with hypertension. Swedish Trial in Old Patients with Hypertension.
It is well established that hypertensive patients benefit from drug treatment of their disorder . In recent years three major out-come studies of antihypertensive treatment in elderly hypertensives have shown substantial benefits , i.e. a reduction in the risk of stroke and other cardiovascular mortality and morbidity . In all these studies beta-blockers and /or diuretics were used in comparison with placebo . Newer therapeutic alternatives have , however , at least theoretically , many advantages which could result in further improvements in prognosis . The initial Swedish Trial in Old Patients with Hypertension ( STOP-Hypertension 1 ) was conducted in men and women aged 70 - 84 years . STOP-Hypertension 2 will evaluate the therapy used in STOP-Hypertension 1 against therapy based on either ACE-inhibitors ( enalapril and lisinopril ) or on calcium antagonists ( isradipine and felodipine ) , using the PROBE design ( Prospect i ve , R and omised , Open , Blinded Endpoint evaluation ) . The primary aim will be to assess the effect on cardiovascular mortality . Statistical calculations indicate that 6,600 patients , followed for four years will be needed ( 2p < 0.05 , power 90 % ) to obtain significance if there is a 25 % difference between the new and the established therapy . Patients in primary health care ( 300 centres ) will be included if their supine blood pressure is > or = 180/105 mmHg ( and /or ) . Recruitment of patients started in September 1992 and so far more than 100 patients /week have been included
