title: Hemodynamic Results of Perorally Administered Converting Enzme Inhibitors in Congestive Heart Failure.
abstract: The acute hemodynamic response to captopril (8 patients) and enalapril (8 patients) was evaluated in congestive heart failure patients in NYHA functional class III. All patients had a history of congestive heart failure for more than six months. The results show marked interindividual variations but average values for cardiac output increase and decrease in filling pressures agree with findings in the literature. 6 patients in the captopril group and five in the enalapril group were started on maintenance therapy. One patient in the captopril group deteriorated and underwent a successful heart transplantation and one patient in the enalapril group returned with arrhytmias and hypertension (probably not drug-related) after 48 h of therapy. Our data indicate that activation of the renin-angiotensin system through excessive administration of loop-diuretics is associated with a risk of hypovolemia and thus drug-induced hypotension that deserves special attention when considering converting enzyme inhibitor therapy in congestive heart failure.
