PCI: percutaneous coronary intervention, CABG: coronary arterial bypass grafting Heart failure (+): history of admission due to heart failure, clinical symptoms due to heart failure confirmed by ultrasound examination, apparently decreased cardiac function by ultrasound examination without clinical symptoms. Renal dysfunction: (−) (60≦), G3a (45–59), G3b (30–44), G4 (15–29), G5 (<15), G5D (<15 with hemodialysis). New CKD risk stratification by eGFR(mL/min/1.73 m²) in “Clinical Practice Guidebook for Diagnosis and Treatment of Chronic Kidney Disease 2012.” eGFR: estimated glomerular filtration rate, CKD: chronic kidney disease
