Cardiovascular diseases are the most common causes of mortality, and hypertension is the most common cardiovascular disease in all ages. The Systolic Hypertension in the Elderly Program (SHEP) trial has shown that the pharmacologic reduction of isolated systolic hypertension can significantly reduce the incidence of cardiovascular complications. The aim of the Italian multicenter study reported here is to compare the efficacy, safety, and tolerability of fosinopril, a novel angiotensin converting enzyme (ACE) inhibitor with a dual route of excretion, with chlorthalidone, the diuretic administered in the SHEP study, in 312 elderly patients with isolated systolic hypertension. Our results show that fosinopril and chlorthalidone produce identical and statistically significant reductions in systolic blood pressure (-23.9 +/- 11.6 mm Hg and -23.7 +/- 10.9 mm Hg, respectively) and, to a lesser extent, in diastolic blood pressure (-7.1 +/- 3.1 mm Hg and -5.2 +/- 2.3 mm Hg, respectively). Only chlorthalidone caused a statistically significant change in uric acid, total cholesterol, blood urea, and serum potassium concentrations. Fosinopril was also somewhat better tolerated than chlorthalidone. In conclusion, the novel ACE inhibitor fosinopril is an effective and well-tolerated antihypertensive agent for use in elderly patients with isolated systolic hypertension and appears to be a suitable alternative for the treatment of isolated systolic hypertension.
