Key result
Female gender is not independently linked to post-CABG death or complications, with morbidity reflecting comorbid risk.

Does female gender independently predict worse postoperative outcomes in patients undergoing primary coronary artery bypass grafting?
Absolute Event Rate: 1.5% vs 1%
After accounting for baseline comorbidities, female gender is not an independent predictor of death or major perioperative complications after primary CABG.
Aldea et al. (1999) conducted a cohort in Coronary artery disease requiring bypass grafting (n=1,743). Female gender vs. Male gender was evaluated on Postoperative death. Female gender was not an independent predictor of postoperative death (1.5% vs 1.0%) or complications after CABG; higher morbidity in women was related to comorbid risk factors.
