Univariate Cox regression analysis of risk factors for 6-months cumulative mortality.

For continuous variables hazard ratios are calculated per unit change. CI = confidence interval; ECC = extracorporeal circulation; HR = hazard ratio; LV = Left ventricular; MI = myocardial injury; NYHA = New York Heart Association class; NT-proBNP = N-terminal prohormone brain natriuretic peptide; PCI = percutaneous coronary intervention; PAP = pulmonary artery pressure; CK-MB = creatine kinase-muscle, brain isotype; TnT = Troponin T.Univariate Cox regression analysis of risk factors for 6-months cumulative mortality.
