Association of gender with morbidity and mortality after isolated coronary artery bypass grafting. A propensity score matched analysis

Abstract Introduction There is conflicting evidence about the impact of gender on outcomes after coronary artery bypass grafting (CABG). Methods We performed a multivariate logistic regression and propensity score matched analyses in 13,115 patients (75% men) who underwent CABG between January 1, 1995 and December 31, 2009. The primary outcome was in-hospital mortality. Secondary outcomes included post-operative respiratory failure, stroke, myocardial infarction, sternal and leg wound infections, atrial fibrillation (AF), renal failure, need for postoperative intra-aortic balloon pump (IABP) support, and length of hospital stay. Results A higher proportion of women (184; 5.6%) suffered in-hospital death compared to men (264; 2.7%), p Conclusions Female gender is an independent predictor of increased mortality and a lower incidence of post-operative AF after isolated CABG.
