  1. No. – number, Reoperation – previous cardiac operation, PCI – percutaneous coronary intervention, MI – myocardial infarction, Diabetes mellitus – treated by subcutaneous insulin or by oral antidiabetics, Supraventricular arrhythmia – atrial fibrillation or atrial flutter, COPD – chronic obstructive pulmonary disease, Renal dysfunction – serum creatinine ≥ 120 umol/l, Cerebral vascular disease – stenosis of carotid artery >70%, CVA – cerebrovascular accident, PAD – peripheral artery disease, Anemia – serum hemoglobin < 12 g/dL (women) or < 13 g/dL (men), LVEF – left ventricular ejection fraction.
