Objectives: To analyze the factors that influence outcomes of surgical myocardial revascularization in the female population. Patients and method: This is a retrospective study in which 128 woman, subjected to GABC[IBM1] from January to September 2004, were enrolled in an univariate and multivariate analysis of risk factors associated with morbidity and mortality. Results: The mean age was 69.19 ± 9.05 [IBM2] years, the most frequent pathologies, comorbilities, were dyslipemia, hypertension, and myocardial infarction. Unestable angina was found in 63.28% patients and stenosis in the left main coronary artery 42.96%; NYHA III-IV in 23.43%. The EuroSCORE mean preoperative risk was [IBM3] 5.57. Twelve surgeries were emergencies. Mean of grafts was 2.57. Mortality corresponded to 5.4% in programmed surgeries, 7% global. Univariate analysis identified this risk factors releated to mortality (p < 0.05): age older than 67 years, NYHA III-IV and emergency surgery, complicated in 25.2%. Follow-up was kept in 90.8% of patients, mean follow-up time was 17.11 (± 14.94) months; 115 patients did not present angina. The risk factor for angina during follow-up, in the univariate analysis (p < 0.05) was not having used the left internal thoracic artery as graft for the anastomosis of the anterior descending artery. Conclusions: Emergency surgery, age older than 67 years, and NYHA III-IV, were independent risk factors associated with mortality in this group. The use of artery grafts associated to reduced angina during follow-up.
