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 .
Efficacy of atenolol and captopril in reducing risk of macrovascular and microvascular complications in type 2 diabetes: UKPDS 39
Abstract Objective : To determine whether tight control of blood pressure with either a β blocker or an angiotensin converting enzyme inhibitor has a specific advantage or disadvantage in preventing the macrovascular and microvascular complications of type 2 diabetes . Design : R and omised controlled trial comparing an angiotensin converting enzyme inhibitor ( captopril ) with a β blocker ( atenolol ) in patients with type 2 diabetes aim ing at a blood pressure of < 150/<85 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 years , mean blood pressure 160/94 mm Hg ) . Of the 758 patients allocated to tight control of blood pressure , 400 were allocated to captopril and 358 to atenolol . 390 patients were allocated to less tight control of blood pressure . Main outcome measures : Predefined clinical end points , fatal and non-fatal , related to diabetes , death related to diabetes , and all cause mortality . Surrogate measures of microvascular and macrovascular disease included urinary albumin excretion and retinopathy assessed by retinal photography . Results : Captopril and atenolol were equally effective in reducing blood pressure to a mean of 144/83 mm Hg and 143/81 mm Hg respectively , with a similar proportion of patients ( 27 % and 31 % ) requiring three or more antihypertensive treatments . More patients in the captopril group than the atenolol group took the allocated treatment : at their last clinic visit , 78 % of those allocated captopril and 65 % of those allocated atenolol were taking the drug ( P<0.0001 ) . Captopril and atenolol were equally effective in reducing the risk of macrovascular end points . Similar proportions of patients in the two groups showed deterioration in retinopathy by two grade s after nine years ( 31 % in the captopril group and 37 % in the atenolol group ) and developed clinical grade albuminuria ≥300 mg/l ( 5 % and 9 % ) . The proportion of patients with hypoglycaemic attacks was not different between groups , but mean weight gain in the atenolol group was greater ( 3.4 kg v 1.6 kg ) . Conclusion : Blood pressure lowering with captopril or atenolol was similarly effective in reducing the incidence of diabetic complications . This study provided no evidence that either drug has any specific beneficial or deleterious effect , suggesting that blood pressure reduction in itself may be more important than the treatment used
