RESUMO
PURPOSE--To evaluate the acute hemodynamic effects of ibopamine (IBO), captopril (CAP) and placebo (PLA) in patients with severe congestive heart failure at rest. METHODS--Twelve male patients in sinus rhythm with dilated cardiomyopathy and NYHA class IV were studied with Swan-Ganz hemodynamics. Drugs were given in a blinded fashion. Rest, 30 min and every hour for 5 h measurements were made after oral ingestion of 100 mg IBO, 25 mg CAP or PLA. Prior to the study, patients were on diuretics as the only medication for at least 48 h. Comparisons were made with analysis of variance of repeated measurements and Duncan's multiple comparisons procedure. RESULTS--Significant increase in cardiac index and stroke volume index and reduction in systemic vascular resistance were observed with IBO and CAP for 2 h after ingestion. IBO however increased right and left filling pressures in the first hour after its administration. Ventricular tachycardia occurred in 2 patients 1 h after IBO administration. CONCLUSION--Both IBO and CAP improved hemodynamic parameters in the first two hours after oral ingestion in patients with dilated cardiomyopathy in class IV.
