Introduction The aim of this study was to evaluate the outcome of coronary artery bypass grafting (CABG) in women compared to men, with focus on short-term and long-term complications, 30 day mortality and survival. Materials and methods This was a retrospective study on all CABG patients operated in Iceland between 2001 and 2013. Clinical information was gathered from hospital charts and survival data was obtained from the National Statistics in Iceland. Overall survival was estimated with the Kaplan- Meier method. Logistic and Cox regression analysis were used to identify predictors of operative mortality and long-term survival. Mean follow-up was 6.8 years. Results Of 1755 patients 318 were women (18%). Women were on average four years older than men at the time of operation (69 vs. 65 yrs, p<0.001). Female patients had a higher incidence of hypertension (72 vs. 64%, p=0.009) and their EuroSCOREst was higher (6.1 vs. 4.3, p<0.001). The prevalence of diabetes, dyslipidemia and the extent of coronary artery disease was comparable between groups. The rate of short-term complications, both minor (53% vs. 48%, p=0.07) and major (27% vs. 32%, p=0.2), was similar and operative mortality for women was not statistically different from males (4% vs. 2%, p=0.08). Female gender was neither found to be a predictor of 30-day mortality (OR 0.99; 95%-CI: 0.98-1.01) nor survival (HR 1,08; 95%-OB: 0,82-1,42). Conclusions The number of women that undergo CABG is low and they are four years older than men when operated on. As is the case with men, outcome following CABG in Iceland is very good for women, their overall five-year survival being 87%.
