The data are shown as mean ± SD or n (%). *Compared by paired t-test; otherwise by McNemar’s test or Fisher’s exact test. CABG: Coronary artery bypass grafting; PCI: Percutaneous coronary intervention; LVEF: Left ventricular ejection fraction; LVEDD: Left ventricular end-diastolic dimension; IABP: Intra-aortic balloon pump; ALT: Alanine aminotransferase; MI: Myocardial infarction; AF: Atrial fibrillation; SD: Standard deviation.
