^*Non-normal distribution. The data are expressed as mean ± standard deviation and median [interquartile range] or number (percentage);

AMI — acute myocardial infarction; CABG — coronary artery bypass grafting; LAD — left anterior descending artery; LMCA — left main coronary artery; LVEF — left ventricular ejection fraction; CX — circumflex artery; RCA — right coronary artery; VSR — ventricular septal rupture; PCI — percutaneous coronary intervention
