Patients aged 60 years and older with essential hypertension were treated with an angiotensin-converting enzyme inhibitor (ACE-I), delapril (Adecut) or a long-acting calcium (Ca)-antagonist, manidipine (Calslot) for 3 years. The incidences of cardiovascular events as well as drug-related side effects were compared between the two groups to investigate whether both classes of antihypertensive drugs are beneficial in elderly hypertensive patients. There were no significant differences in characteristics of patients between the two intervention groups, except for slightly lower blood pressure (P = .08) in the Ca-antagonist group at the initiation of the study. There were no significant differences in total death between the two groups. Cardiovascular events (both fatal and nonfatal) were noted in 34 of 699 patients (22.5/ 1000 patient-years) in the ACE-I group and 50 of 1049 patients (19.7/1000 patient-years) in the Ca-antagonist group, with no significant difference found between the two groups. The correlation between cardiovascular incidence and the blood pressure attained during treatment showed a J-shaped phenomenon and suggests that an excessive reduction less than 120 mm Hg in systolic blood pressure (SBP) is unnecessary and may be harmful in certain cases. Side effects were more frequent in the ACE-I group than in the Ca-antagonist group (P = .01). Cough was the major adverse event, occurring in 5.0% of patients in the ACE-I group. In conclusion, the study indicates that both ACE-I (delapril) and Ca-antagonist (manidipine) were equally beneficial for reducing cardiovascular morbidity and mortality in elderly hypertensive patients. However, tolerability of ACE-I was lower due to the adverse event of coughing. (C) 2000 American Journal of Hypertension, Ltd.
