BackgroundThe aim of this study was to evaluate the relationship between the preoperative N-terminal pro-B-type natriuretic peptide (NT-proBNP) level and the need for the inotropic support in the early postoperative period of patients undergoing coronary artery bypass graft surgery.Methods And ResultsThe patients were divided into 2 groups: NT-proBNP level<220 pg/ml (group A, n=26) or >220 pg/ml (group B, n=26). The normal value for NT-proBNP level was accepted as <220 pg/ml. The cardiac output was measured on arrival in intensive care and at the 16th hour. The groups were compared with respect to early postoperative hemodynamic measurements, urinary output, use of inotropic agents and requirement for additional cardiac-assist devices. Left ventricular ejection fraction, cardiac output and cardiac index were lower in group B and inotropic agents were used for a longer period of time and at higher doses in this group (p<0.05).ConclusionMeasurement of the NT-proBNP level in the period before cardiac surgery can indicate the postoperative prognosis of the patient and may be a predictor of the need for postoperative inotropic treatment.
