Results of stepwise multiple linear regression analysis predicting early clinical course

Dependent variable	Predictors	β	P
ICU time Adjusted R² = 0,22	6 IL-6	0.52	0.012
CAI max Adjusted R² = 0.67	5 CKMB	0.46	0.0008
CAI max Adjusted R² = 0.67	5 TnI	0.65	0.00002
Respiratory support time Adjusted R² = 0.15	6 IL-8	0.43	0.03
Effusion’s duration Adjusted R² = 0.18	5 TnI	0.41	0.04

All factors found to be significant in RMANOVA analysis were taken into the multiple linear regression models. ICU time intensive care unit hospitalization time, CAI max maximal catecholamine index, 6 IL-6 interleukin 6 concentration at ICU (4 h after surgery), 6 IL8 interleukin concentration at ICU (4 h after surgery), 5 CKMB creatine kinase myocardial isoenzyme activity after by-pass discontinuation, 5 TnI troponin I after by-pass discontinuation
