Abstract

Objective: This study aimed to evaluate the role of plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) level in the diagnosis of postoperative acute heart failure of patients undergoing coronary artery bypass graft surgery. Subject and method: Prospective study in 107 patient undergoing coronary artery bypass graft surgery at Ho Chi Minh Heart Hospital from October 2012 to June 2014. Result: Patients with EuroScore over 5 was 71%. 25 patients diagnosed postoperative acute heart failure. In patients with isolated CABG, receiver operating characteristics (ROC) analysis showed an area under the curve (AUC) 0.87 for acute heart failure respectively with the best cut-off for NT-proBNP of 951.5pg/mL at postoperative day 1 (POD 1). The sensitivity, specificity and Youden index were 92.3%, 78.7% and 0.71. Conclusion: Plasma N-terminal pro-B-type natriuretic peptide was valuable in the diagnosis of postoperative acute heart failure of patients undergoing coronary artery bypass graft surgery with the best cut-off for NT-proBNP of 951.5pg/mL at postoperative day 1.
