Operative Mortality in Women versus Men in Patients Undergoing Coronary Artery Bypass Grafting.

Abstract

Objective: The aim of this study is to evaluate the effect of gender on the post operative results of patients who underwent coronary artery bypass grafting (CABG). In this study we will assess the clinical outcomes between High risk women and men after coronary artery bypass graft surgery (CABG). Methods: Between October 2009 and August 2011, 220 high-risk patients were retrospectively divided into two groups:(group A) 110 patients (50%) males and (group B) 110 patients (50%) females, both groups underwent CABG. The average age of both groups was of no difference (53.8 and 55.1) years respectively. Hospital mortality and morbidity were the primary end-points of the study. Results: A significant effect modification by gender was found, so the mortality in (group A) was 3 patients (2.73%) however it went higher in (group B) 7 patients (6.63%). Myocardial infarction in men versus women was (6.42% vs. 12.11%) and recurrent angina (10.24%, 18.72% p value 0.004). Women with diabetes experience much greater postoperative risks compared with the non diabetic population than do men with diabetes. Conclusion: The present study indicates that women are at increased risk of operative mortality after isolated CABG compared to men, despite adjustment for preoperative risk factors.
