Risk factors to hospital mortality in valvar reoperations

Abstract

Rev Bras Cir Cardiovasc 2002; 17(4) Results: The overall hospital mortality was 8.8% (17 patients). Univariate analysis showed that the following variables were associated with higher mortality rates: advanced New York Heart Association functional class, decreased left ventricular ejection fraction, decreased prothrombin activity, increased creatinine level, longer aortic cross-clamping time, prolonged cardiopulmonary bypass time, concomitant associated procedures, and higher intraoperative bleeding volume. Logistic multivariate analysis identified advanced New York Heart Association functional class, creatinine level higher than 1.5 mg/dl, and cardiopulmonary bypass time longer than 120 minutes as independent predictors of hospital mortality.Conclusions: The variables functional class IV, creatinine level > 1.5 mg/dl and cardiopulmonary bypass time > 120 min were independent predictors of hospital mortality in valvar reoperations.
