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 .
We wanted to know what the effects of therapy are in people 18 to 59 years of age .
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 .
Comparison of the antihypertensive efficacy and adverse reactions to two doses of bendrofluazide and hydrochlorothiazide and the effect of potassium supplementation on the hypotensive action of bendrofluazide: substudies of the Medical Research Council's trials of treatment of mild hypertension: Med
As sub studies of the Medical Research Council 's trials of treatment of mild hypertension and of hypertension in the elderly , two studies were carried out comparing the effects of different doses of two diuretics on blood pressure , concentrations of some biochemical variables , and the incidence of subjective adverse reactions . In one study , in which 484 patients with mild hypertension participated , daily doses of bendrofluazide 5 mg and 10 mg , with and without oral potassium supplements , were compared . In the second , involving 701 elderly patients with hypertension , daily doses of hydrochlorothiazide 25 mg together with amiloride 2.5 mg were compared with hydrochlorothiazide 50 mg together with amiloride 5 mg . The mean ( + /- SD ) duration s of treatment were 35 + /- 17 months in the first study and 10 + /- 7 months in the second . Neither study showed any significant difference in blood pressure response to the two doses of diuretic , whereas biochemical changes and the reported incidence of subjective adverse reactions were dose-related . In the first study , potassium supplementation with potassium chloride 16.8 or 33.6 mmol did not have a significant effect on the fall in serum potassium level , which was only slightly reduced , and did not have any significant effect on the antihypertensive effect of either dose of bendrofluazide
