Randomized Controlled Trial Clinical TrialEffects of prostaglandin E1, dobutamine and placebo on hemodynamic, renal and neurohumoral variables in patients with advanced heart failure.
Excessive neurohumoral activity remains a major burden to the circulation of patients with advanced heart failure. Prostaglandin E1 (PGE1), a balanced i.v. vasodilator, was shown to elicit favorable hemodynamic and clinical effects in this cohort. A prospective randomized parallel group trial was performed to evaluate acute, intermediate and chronic changes in hemodynamic, neurohumoral and renal variables in response to PGE1, dobutamine and placebo. ⋯ Except a slight decrease in right atrial pressure after 7 days placebo did not change any measured variable significantly. Taken together, these data suggest that treatment with PGE1 is as efficacious as low-dose dobutamine in improving cardiac performance and renal perfusion in advanced heart failure. Of importance, no deleterious neurohumoral counterregulation was observed with PGE1.
