Background: The preoperative management of patients who will undergo coronary artery by pass graft surgery (CABG) can be used to identify risk factors for the postoperative complications.

Objectives: To asses the clinical characteristics of the patients and the incidence of adverse events. To identify risk factors associated with a higher rate of postoperative complications.

Methods: Between 1997and 2000, 138 patients (P) underwent (CABG) in our center. Risk factors were evaluated with univariated analysis. Those who had a higher rate of adverse events in the postoperative period were identified.

Results: The mean age was 64,5 years; 78,2% were male; 34% were older than 70 years; 29% had previous myocardial infarction; 17,4% had ejection fraction <45%; 13,7% had left main coronary disease >50%; 52,1%, 3 vessel disease. 8,7% were emergency operations.24% had chronic obstructive pulmonary disease (COPD). The mortality at discharge was 5,8%. Fig. 1

Conclusions: Risk factors associated with a higher mortality were age older than 70 years old, ejection fraction <45%, emergency CABG and COPD. The predictors of postoperative adverse events were: age older than 70 years old, emergency CABG, COPD and peripheral vascular disease.
