Preoperative NT-proBNP and primary endpoint. A NT-proBNP of 443 pg/ml had the highest accuracy in predicting the composite endpoint (area under the receiver operating characteristic curve 0.679, p < 0.001, Youden’s index 0.363, sensitivity 55.6%, specificity 80.7%, dotted line). B Distribution of NT-proBNP in both analysed groups. C Kaplan-Meier estimates revealed adverse 30-day outcomes in patients with preoperative NT-proBNP > 450 pg/ml (composite morbidity endpoint consisting of rehospitalisation, acute decompensated heart failure, acute kidney injury, and any bacterial infection). ***p < 0.001
