DIFERENÇA DA MORTALIDADE ENTRE OS SEXOS APÓS CIRURGIA DE REVASCULARIZAÇÃO DO MIOCARDIO

Abstract

Objective: To compare the mortality of men and women undergoing coronary artery bypass surgery (CABG) alone and identifying factors related differences occasionally found. Methods: Retrospective cohort study conducted with 215 patients who underwent coronary bypass surgery consecutively from January 2007 to December 2008. Results: Women had a higher average age. Low body surface and dyslipidemia was more prevalent in women (1.65 vs. 1.85, p <0.001: 53% vs 30%, p = 0.001), whereas smoking history and previous myocardial infarction were more prevalent among men (35 % vs 14.7% p = 0.001, 20% vs 2.7%, p = 0.007). Regarding the complications in the postoperative period, there was a higher rate of transfusions in women. The overall mortality rate was 5.6%, however there was no statistically significant difference in mortality between men and women. It was observed that among patients who died the mean body surface was lower than that of patients who progressed without this complication. Conclusion: There was no difference in mortality between the sexes after CABG in our department.
