Data are mean±SD or number (percentage). CABG indicates coronary artery bypass grafting; CKD, chronic kidney disease; CVA, cerebrovascular accident; LV, left ventricular; MI, myocardial infarction; MV, multivessel; NSTEMI, non–ST‐segment–elevation myocardial infarction; PCI, percutaneous coronary intervention; PVD, peripheral vascular disease; and STEMI, ST‐segment–elevation myocardial infarction.
