Patients with left ventricular ejection fraction below 45% (mean 39+/-3.7%) were randomized either to captopril (n=33) or eprosartan after miocardial infarction (n=33) on days 3-7 of myocardial infarction. All patients were subjected to echocardiography and 40 to perfusion myocardial scintigraphy with (99m)TC-Technetril. Myocardial viability was defined as presence of perfusion reserve in dysfunctional segments during test with nitroglycerin. Dysfunctional myocardium was found to be viable in 62.5% of patients. Fifty six patients completed 3 months follow up and were restudied. By the time of the second study 28 patients continued captopril (37.5-150 mg, average dose 72+/-34.2 mg/day) and 28 - eprosartan (300-600 mg, average dose 471+/-151 mg/day). Captopril was stopped or its dose corrected in 28% of patients. In eprosartan group there were no side effects which required withdrawal of the drug. Similar increases of ejection fraction occurred on both groups (from 38+/-2.1 to 49+/-6.7%, p0.001 and from 39+/-4 to 51+/-6.5%, p0.001, in eprosartan and captopril groups, respectively). Magnitude of left ventricular ejection fraction change did not depend on the presence of viable myocardium. However in both treatment groups improvement of myocardial perfusion and decrease of left atrial dimensions were found only in patients with viable myocardium at initial study. |
