Table 1 represents all data and values for echocardiography. The postmyocardial infarct values of the LAD study are measured with 3D echocardiography. LCx indicates left circumflex artery. LAD: left anterior descending artery; LVEF: left ventricular ejection fraction; LVEDV: left ventricular end-diastolic volume; LVESV: left ventricular end-systolic volume. BL: baseline before infarct, PMI: post myocardial infarct. *Repeated measures ANOVA (values compared to baseline), #Student’s -test.
