Receiver operating characteristics (ROC) to evaluate discrimination of postoperative NT-proBNP for severe PHF. Left panel (a) demonstrates discrimination of NT-proBNP on POD1 for severe PHF (AUC = 0.86; 95% CI 0.76–0.95; p = 0.001, best cut-off 4574 ng/L with a sensitivity of 71%, n = 320). Right panel (b) demonstrates discrimination of NT-proBNP on POD3 for severe PHF (AUC = 0.79; 95% CI 0.55–1.00; p = 0.015, best cut-off 6065 ng/L with a sensitivity of 83% and a specificity of 77%, n = 325). AUC area under curve, CI confidence interval, POD1 postoperative day 1, POD3 postoperative day 3
