  1. COPD = chronic obstructive pulmonary disease; MI = myocardial infarction; mod = moderate; PCI = percutaneous intervention; NYHA = New York Heart Association; LVEF = left ventricular ejection fraction; LVEDD = left ventricular end-diastolic diameter; LVESD = left ventricular end-systolic diameter; LAD = left atrial diameter; SPAP = systolic pulmonary artery pressure; Left main disease = left main coronary stenosis; 3-vessel disease = triple coronary stenosis; MR = mitral regurgitation NS = not significant;
