Résumé
The present study was carried out on 100 patients with acute myocardial infarction (AMI) being treated with angiotensin converting enzyme (ACE) inhibitor and another 80 patients with conventional treatment but without ACE inhibitor during the period from May 1, 1995 to August 7, 1996 in Medical College, Calcutta. Clinical and other laboratory investigations including echocardiographic parameters were noted and recorded meticulously within 24-48 hours after AMI and repeated at 4th week. The present study based on non-invasive methods other than haemodynamic methods has shown that the echocardiographic assessment of left ventricular functional parameters after 4 weeks of ACE inhibitor therapy (n = 100) were better in treated group in comparison to control group without ACE inhibitor (n = 80) and the difference was statistically significant at 99% level of confidence. Overall mortality was 4% in ACE inhibitor group and 8.75% in the control group. This short term study with early intervention with ACE inhibitor within 48 hours of AMI has shown statistically significant evidence of beneficial effect of ACE inhibitor in improving the ventricular functional parameters and also reducing short term mortality from cardiac cause within 4 weeks compared to the group not receiving ACE inhibitors.
