  1. Continuous variables were expressed in mean ± SD or median (IQR) as indicated
  2. ACC: American College of Cardiology; AHA: American Heart Association; CABG: coronary artery bypass graft; DES: drug eluting stent; GFR: glomerular filtration rate; HbA1c, hemoglobin A1c; HDL: high density lipoprotein; LDL: low density lipoprotein; LV: left ventricular; MDRD: Modification of Diet in Renal Disease; MI: myocardial infarction; PCI: percutaneous coronary intervention; PRU: P2Y12 Reaction Unit; WBC: white blood cell
  3. *Hypertension was diagnosed by one of the followings: (1) history of hypertension diagnosed and treated with medication, diet and/or exercise; (2) blood pressure greater than 140 mmHg systolic or 90 mmHg diastolic on at least 2 occasions; or (3) currently on antihypertensive pharmacologic therapy.; Dyslipidemia was diagnosed by one of followings: (1) total cholesterol ≥ 200 mg/dl; (2) LDL cholesterol ≥ 130 mg/dl; (3) HDL cholesterol < 40 mg/dl; or (4) triglycerides ≥ 150 mg/dl; Current smoker was defined as use of tobacco within one year of this admission; Diabetes mellitus was diagnosed by one of the followings: (1) a history of diabetes, regardless of duration of disease, or need for antidiabetic agents; (2) a fasting blood glucose ≥ 126 mg/dl; or (3) glycosylated hemoglobin ≥ 6.5; Chronic kidney disease was diagnosed by one of the followings: (1) GFR < 60 mL/min/1.73m2 (MDRD); (2) on dialysis; or (3) history of a renal transplantation; Anemia was defined as hemoglobin level < 12 g/dl in women and 13 g/dl in men
  4. †First-generation DES indicated durable polymer-based paclitaxel-eluting stents (PES: Taxus, Pico) or sirolimus-eluting stent (SES: Cypher); Second-generation DES indicated next-generation DESs including everolimus-eluting stent (EES: Promus, Xience), zotarolimus-eluting stent (ZES: Endeavor, Resolute, Onyx), biolimus-eluting stent (BES: Biolimus A9), and plymer-free SES.; If a patient were treated with first- and second-generation DESs together, this patient was considered as implantation with first generation DES.
