title: Long-term effects on cardiac output and peripheral resistance in patients treated with enalapril after acute myocardial infarction. CONSENSUS II Multi-Echo Study Group. Cooperative New Scandinavian Enalapril Survival Study.
abstract: In the Cooperative New Scandinavian Enalapril Survival Study (CONSENSUS II), in which enalapril treatment was initiated intravenously within 24 h after acute myocardial infarction, there was a neutral effect on 6-month mortality, whereas a beneficial effect on the progression of congestive heart failure was noted. We studied the effect of enalapril on left ventricular systolic function in terms of cardiac output and mean acceleration time measured by pulsed-wave Doppler in the left ventricular outflow tract and peripheral resistance. Early angiotensin-converting enzyme inhibition after acute myocardial infarction did not result in a general improvement of cardiac output. However, a small increase in cardiac output was observed in a subgroup of enalapril-treated patients with ejection fraction > or = 45%, probably due to a reduction in peripheral resistance in these patients.
