These investigators examined the long term (4.8 years) benefits of treating hypertension with either losartan or atenolol.
9,193 (1195) patients mean age 67, 54% women, 25% (35%) history of vascular disease. Numbers in brackets are the the subset of patients who were diabetic at entry into the trial.
Losartan 50-100 mg PO daily or atenolol 50-100 mg PO daily. Approximately 25% required additional drugs
|CV mortality, MI, stroke (%)||All deaths||MI's (%)||Stokes (%)||CV Mortality (%)|
|Relative Risk Reduction||15||22||Stats not done||NSS||35||Stats not done||NSS||Stats not done||29||NSS||Stats not done||NSS||Stats not done|
|Absolute Risk Reduction||2||5||6||2|

T= total, D = diabetic, ND = nondiabetic, NSS = not statistically significant
Systolic blood pressure was lowered by 1.1 mmHg more in the losartan group compared to the atenolol group.
This study shows that losartan decreases the chance of cardiovascular events and deaths by more (2% and 6% respectively) than atenolol in patients with hypertension. The benefit was greater in diabetic patients than in patients without diabetes. Unfortunately, thiazide diuretics, the drugs of choice for hypertension were not used as a comparison in this trial.
