Results:Accuracies of C-reactive protein,cardiac troponin I,and B-type natriuretic peptide,considered as continuous variables,to predict the occurrence of major adverse cardiac events were limited (area under receiver operating characteristic curve:0.54 [0.47-0.60],P = 0.42; 0.62 [0.55-0.68],P = 0.01; and 0.68 [0.61-0.74],P < 0.001,respectively).When biomarkers were considered as 75% specificity dichotomized variables,elevated C-reactive protein (> 180 mg/l),cardiac troponin I (> 3.5 ng/ml),and B-type natriuretic peptide (> 880 pg/ml) were independent predictors of major adverse cardiac events (odds ratio:2.14 [1.03-4.49],P = 0.043; 2.37 [1.25-5.64],P = 0.011; and 2.65 [1.16-4.85],P = 0.018,respectively) in a multivariate model including the European System for Cardiac Operative Risk Evaluation score.
