  • B-type natriuretic peptide levels predict outcome after neonatal cardiac surgery JOURNAL OF THORACIC AND CARDIOVASCULAR SURGERY Hsu, J., Keller, R. L., Chikovani, O., Cheng, H., Hollander, S. A., Karl, T. R., Azakie, A., Adatia, I., Oishi, P., Fineman, J. R. 2007; 134 (4): 939-945


    Neonates undergoing cardiac surgery are at high risk for adverse outcomes. B-type natriuretic peptide is used as a biomarker in patients with cardiac disease, but the predictive value of B-type natriuretic peptide after cardiac surgery in neonates has not been evaluated. Therefore, the objective of this study was to determine the predictive value of perioperative B-type natriuretic peptide levels for postoperative outcomes in neonates undergoing cardiac surgery.Plasma B-type natriuretic peptide determinations were made before and 2, 12, and 24 hours after surgery in 36 consecutive neonates. B-type natriuretic peptide levels and changes in perioperative B-type natriuretic peptide were evaluated as predictors of postoperative outcome.B-type natriuretic peptide levels at 24 hours were lower than preoperative levels (24-h/pre B-type natriuretic peptide ratio < 1) in 29 patients (81%) and higher (24-h/pre B-type natriuretic peptide ratio > or = 1) in 7 patients (19%). A 24-hour/pre B-type natriuretic peptide level of 1 or greater was associated with an increased incidence of low cardiac output syndrome (100% vs 34%, P = .002) and fewer ventilator-free days (17 +/- 13 days vs 26 +/- 3 days, P = .002), and predicted the 6-month composite end point of death, an unplanned cardiac operation, or cardiac transplant (57% vs 3%, P = .003). A 24-hour/pre B-type natriuretic peptide level of 1 or greater had a sensitivity of 80% and a specificity of 90% for predicting a poor postoperative outcome (P = .003).In neonates undergoing cardiac surgery, an increase in B-type natriuretic peptide 24 hours after surgery predicts poor postoperative outcome.
