  1. Regarding risk factors, clinical history and symptoms we reported the number of patients for whom these data area vailable. SD standard deviation, LVEF left ventricle ejection fraction, IDDM insulin-dependent diabetes mellitus, MI myocardial infarction, CABG coronary artery bypass grafting, PCI percutaneous coronary intervention, and HF heart failure
