title: Addition of captopril versus increasing diuretics in moderate but deteriorating heart failure: a double-blind comparative trial.
abstract: In 15 patients with moderate congestive heart failure not completely controlled on digoxin (0.25 mg o.d.) and frusemide (25 mg o.d.), we compared the addition of captopril (12.5 to 50 mg b.i.d.) with increasing doses of frusemide (25 to 100 mg o.d.), in a randomized double-blind, double-dummy, comparative trial. Thirteen patients completed the 3 months study: two dropped-out in the frusemide group. Statistically significant clinical improvement occurred in both treatment groups. Exercise tolerance also significantly improved in both groups in a parallel fashion. Echocardiographic cardiac function data showed a significantly better pattern of changes in the captopril group. The addition of low doses of captopril to basal therapy seems to be as effective as the addition of high doses of frusemide in uncontrolled moderate congestive heart failure. This approach with captopril also appears to be more physiological and safe.
