[Enalapril reduces the degree of left ventricular remodeling after acute myocardial infarction and reduces the incidence of arrhythmia in ischemic disease].

The present study shows that enalapril prevents the excessive remodeling of the left ventricle after acute myocardial infarction. This randomized and double blind clinical study analysed 50 patients with an inferior myocardial infarction. The effect of enalapril was evaluated through cardiac volumes, ejection fraction, neurohormonal levels and incidence of the left ventricle disfunction after acute myocardial infarction. The patients treated with enalapril showed a significant reduction on the values of nor-epinefrine, angiotensine II, natriuretic hormone and vasopressine, four weeks after initiation of treatment. The ejection fraction and the level of the wall movement was more favourable, four weeks after infarction, in the group treated with enalapril. The incidence of congestive heart failure and arrhythmias was lower in the group treated with enalapril. So, we conclude that enalapril is a drug that prevents the excessive remodelling of the left ventricle after an acute myocardial infarction.
