  1. Values are presented as mean ± SD. SVD, single-vessel disease; CR, complete revascularization; IR, incomplete revascularization; BMI, body mass index; CK, creatinine kinase; LVEDD, left ventricular end-diastolic diameter; LVEF, left ventricular ejection fraction; IRA, infarct-related artery; LM, left main coronary artery; LAD, left anterior descending coronary artery;LCX, left circumflex artery; RCA, right coronary artery; CPET, cardiopulmonary exercise testing; RAAS, renin-angiotensin-aldosterone system. *p < 0.05 compared with SVD group.
