The long-term mortality of coronary artery bypass grafting in women in not certain. The purpose of this study was to determine and compare risk factors for long-term mortality in women and men undergoing coronary artery bypass grafting.

Between 1992 and 2002, 3760 consecutive patients (2598 men and 1162 women) underwent isolated coronary artery bypass grafting. Long-term survival data were obtained from the National Death Index (mean follow-up, 5.1 ± 3.2 years). Multivariable Cox regression analysis was performed, including 64 preoperative, intraoperative, and postoperative factors separately in women and men.

There were no differences in in-hospital mortality (2.7% in men vs 2.9% in women, P = .639) and 5-year survival (82.0% ± 0.8% in men vs 81.1% ± 1.3% in women, P = .293). After adjustment for all independent predictors of long-term mortality, female sex …
