Abstract

Introduction and objectives: The knowledge of predictive factors for mortality and severe complications is of great importance, since it allows an objective preoperative assessment of patients. The aim of this study was to determine risk factors predictive for mortality and severe complications in revascularized patients without the use of extracorporeal circulation,  and to analyze the behavior of two models of preoperative risk stratification in cardiac surgery. Method: A non-experimental, prospective follow-up investigation was conducted in which 175 patients who received coronary artery bypass grafting without the use of extracorporeal circulation, in the Cardiac Surgery Department of "Ernesto Che Guevara" Cardiology Hospital of Villa Clara, in the years 2007-2009, were studied. In order to determine the predictive variables two bivariate studies were performed in which the dependent variables were mortality and the presence of serious complications. For analysis and validation of the scales applied to operated patients the diagnostic performance curves were used. Results: The studied patients had a mean age of 58,7 years, predominantly male, and hypertension, stable angina, dyslipidemia and diabetes mellitus were the most common risk factors. These patients were all electively operated on, with functional class III and there was a predominance of the three vessel coronary disease. The variables that significantly affected the risk of death and serious complications were: trunk disease and three vessel disease, a history of peripheral vascular disease, unstable angina and chronic obstructive pulmonary disease. Conclusions: The risk scores used have good predictive power of mortality and serious complications.
