  1. *Differences between the groups. On the electrocardiogram at 48 hours after acute myocardial infarction. §Difference between group 1 and 2. Values are shown as means ± SD unless otherwise indicated. ACE, angiotensin converting enzyme; LVEDV, left ventricular end-diastolic volume; LVEF, left ventricular ejection fraction; LVESV, left ventricular end-systolic volume; NA, not applicable; WMI, wall motion score index.
