Multiple studies have shown that women have worse in-hospital outcomes than men after coronary artery bypass grafting (CABG). The impact of sex on long-term results following CABG, however, is not as well established.
To compare long-term results in men and women undergoing CABG.
A total of 3404 patients underwent isolated CABG between 1995 and 1999 with follow-up until 2000. Univariate comparisons between men and women were carried out based on pre- and intraoperative variables and short- and long-term adverse outcomes. Long-term adverse outcomes were defined as all-cause mortality or rehospitalization for any cardiac cause, and were risk-adjusted using multivariate modelling techniques.
Compared with men, women undergoing CABG were, on average, older (67.8 years versus 64.2 years), more likely to have diabetes (P
