Methods: Retrospective study involving 491 consecutive patients operated between May/2007 and December/2010. The registers contained all the information used to calculate the scor e. The outcome of inter est was AF . W e calculated association of model factors with AF (univariate analysis and multivariate logistic regression analysis), and association of risk scor e classes with AF . Result s: The incidence of AF was 31.2%. In multivariate analysis, the four variables of the score were predictors of postoperative AF: age >70 years (OR 6.82; 95%CI 3.34-14.10; P <0.001), mitral valve disease (OR 3.18; 95%CI 1.83-5.20; P <0.001), no use of beta-blocker or discontinuation of its use in the postoperative period (OR 1.63; 95%CI 1.05-2.51; P =0.028), total fluid balance > 1500 ml at first 24 hours (OR 1.92; 95%CI 1.28-2.88; P =0.002). W e observed that the higher the risk class of the patient (low , medium, high, ver y high), the gr eater is the incidence of postoperative AF (4.2%; 18.1%; 30.8%; 49.2%), showing that the model seems to be a good pr edictor of risk of postoperative AF , in a statistically significant association ( P <0.001). Conclusions: The Brazilian score proved to be a simple and objective index, revealing a satisfactory predictor of development of postoperative AF in patients undergoing heart valve surgery at our institution. 2012 artículo científico 0102-7638 https://www.redalyc.org/articulo.oa?id=398941884017 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.1 Vol.27 |
