Twelve patients with moderately severe congestive heart failure underwent the simultaneous determination of central and regional hemodynamics after administration of placebo and enoximone. The regions examined hemodynamically included renal, hepatics-planchnic and upper limb. Enoximone was studied in 2 doses, 1 and 2 mg/kg, and administered in a double-blind, placebo-controlled, crossover design. At these doses enoximone elicited a significantly greater increase in cardiac output and a greater decrease in systemic vascular resistance than placebo. Systemic blood pressure was not significantly altered. Enoximone did not significantly change the flow or resistance of renal or hepatic-splanchnic vascular beds. Limb vascular resistance decreased modestly after enoximone with a significant augmentation (+12% to 17%) of limb blood flow compared with placebo. The initial oral administration of the 1 and 2 mg/kg doses of enoximone improved central hemodynamic parameters with apparent preferential reduction of limb vascular resistance and augmentation of blood flow to the limb region (peripheral musculoskeletal system).
