Description
Summary:Purpose This study was conducted to investigate predictors of mortality before and after isolated coronary artery bypass grafting (CABG). Methods Single-institutional data on risk factors and mortality were collected for 8890 patients who underwent isolated CABG by the same group of surgeons. The relationship between risk factors and outcome was assessed using univariate and multivariate analyses in two risk models: a preoperative model (model 1) and then a pre-, intra-, and postoperative model (model 2). Results The mean age of the patients (25.4% women and 74.6% men) was 58.5 ± 9.7 years. Fifty-five (0.6%) patients died after surgery. Hypercholesterolemia was the most common comorbidity factor (61.1%), followed by hypertension, a smoking habit, recent myocardial infarction (MI)
