Inhibition of the renin-angiotensin system does not reduce platelet activity at rest or during stress in hypertension

Objectives:We investigated the influence of angiotensin receptor blockade and angiotensin-converting enzyme inhibition on stress-induced platelet activation in hypertensive patients. Secondary aims were effects on inflammation, coagulation, and endothelial function. Methods:Following a 4-week placebo period, 25 hypertensive patients entered a double-blind, crossover study comparing enalapril (20 mg once daily) and losartan (100 mg once daily) treatment (each for 8 weeks). Patients were studied at rest and after a standardized exercise test. Results:Mean arterial pressure was reduced from 119 ± 2 to 104 ± 2 (enalapril) and 106 ± 2 (losartan) mmHg (both P
