Receiver operating characteristics (ROC) to evaluate discrimination of postoperative NT-proBNP for PHF. Left panel (a) demonstrates discrimination of NT-proBNP on POD1 for PHF (AUC = 0.70; 95% CI 0.61–0.79; p < 0.0001, best cut-off 1836 ng/L with a sensitivity of 90% and a specificity of 46%, n = 320). Right panel (b) demonstrates discrimination of NT-proBNP on POD3 for PHF (AUC = 0.70; 95% CI 0.60–0.81; p < 0.0001, best cut-off 6065 ng/L with a sensitivity of 57% and a specificity of 79%, n = 325). AUC area under curve, CI confidence interval, POD1 postoperative day 1, POD3 postoperative day 3
