Beneficial effect of angiotensin II type 1 receptor blocker antihypertensive treatment on arterial stiffness: the role of smoking.

The purpose of the present study was to assess angiotensin receptor blocker (ARB) treatment on arterial stiffness in select hypertensive patients and define possible differences between smokers and nonsmokers. The authors evaluated 81 consecutive, nondiabetic patients (mean age, 52 years; 47 men) with uncomplicated essential hypertension with high plasma renin activity who were administered monotherapy with irbesartan, an ARB, at maximal dose. Patients were divided into smokers (n=24) and nonsmokers (n=57).
