Fs. Garri et al., EFFECTS OF ENALAPRIL ON LEFT-VENTRICULAR FUNCTION AND EXERCISE PERFORMANCE AFTER A FIRST ACUTE MYOCARDIAL-INFARCTION, International journal of cardiology, 59(3), 1997, pp. 257-265
Aims: To study the effects of early use of enalapril on left ventricul
ar function and exercise capacity after a first acute myocardial infar
ction, 356 patients without overt signs of congestive heart failure we
re randomly allocated to receive placebo or enalapril between days 7 a
nd 14 after a first myocardial infarction. The study was conducted dou
ble-blind in 40 hospitals throughout Spain. Methods and results: At ba
seline and after 26 weeks of follow-up exercise stress tests, Doppler-
echocardiograms and isotopic ventriculography were performed in study
participants. At the end of follow-up, patients in the enalapril group
had lower end-systolic volume compared to those in the placebo group
(55 vs. 62 ml, P=0.05). No difference in exercise capacity was evident
between both groups. Conclusion: The present study shows that enalapr
il therapy administered between 7 and 14 days after a first acute myoc
ardial infarction decreases end-systolic volume and may inhibit the re
modeling process of the left ventricle. (C) 1997 Elsevier Science Irel
