- Predictors of mortality in cardiac surgery: brain natriuretic peptide type B Jamil Alli Murad Junior Marcelo Arruda Nakazone Mauricio de Nassau Machado Moacir Fernandes de Godoy Medicina Hospital Mortality Prospective Studies Natriuretic Peptides Cardiovascular Surgery Procedures Objective: We evaluated whether the preoperative serum concentration of brain natriuretic peptide (BNP) is a predictor of in-hospital mortality in patients that underwent cardiac sur - gery. Methods : We continuously evaluated 488 patients that un - derwent cardiac valve surgery or coronary artery bypass graft - ing (CABG) between January of 2009 and July of 2012. Follow up of these patients were done prospectively for 30 days post - operatively. Results: Data analysis showed that the overall mortality rate was equal to 9.6%, Receiver Operating Charactheristic (ROC) curve analysis found the optimal cut-off value of BNP equal to 382 pg/mL for overall mortality (AUC=0.73, 95% CI=0.66 to 0.81, P <0.001). Multivariate analysis showed that the value of BNP higher than 382 pg/mL ( P =0.033, HR=2.05, 95% CI=1.6 to 3.98) was an independent predictor of overall mortality at 30 days postoperatively. Conclusion : We concluded that the preoperative serum con - centration of BNP is an independent predictor of mortality in patients undergoing valve surgery or coronary artery bypass graft. 2015 artículo científico 0102-7638 https://www.redalyc.org/articulo.oa?id=398941897008 en http://www.redalyc.org/revista.oa?id=3989 Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery application/pdf Sociedade Brasileira de Cirurgia Cardiovascular Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery (Brasil) Num.2 Vol.30
