Objectives: Women undergoing isolated coronary artery bypass graft (CABG) surgery have been previously shown to be at an independently increased risk for post-operative morbidity and mortality. However, there are considerably less data on whether this trend remains true in patients undergoing concomitant aortic valve replacement (AVR) and CABG surgery. The aim of our study was to investigate this pertinent issue. Methods: Data obtained between June 2001 and December 2009 by the Australasian Society of Cardiac and Thoracic Surgeons Cardiac Surgery Database Program were retrospectively analysed. Demographic, operative data and post-operative complications were compared between male and female patients using chi(2) and t tests. Long-term survival analysis was performed using Kaplan-Meier survival curves and the log-rank test. Independent risk factors for short- and long-term mortality were identified using binary logistic and Cox regression, respectively. Results: Concomitant AVR and CABG surgery was undertaken in 2,563 patients; 31.8% were female. Female patients were older (mean age 76 vs. 73 years; p < 0.001) and presented more often with hypertension (p < 0.001) but less often with severely impaired ejection fraction (p < 0.001), peripheral vascular disease (p < 0.001) and triple vessel disease (p < 0.001). Women did not demonstrate an increased risk of 30-day mortality (4.8 vs. 3.3%) on univariate (p = 0.069) or multivariate (p = 0.236) analysis. Female gender was independently associated with post-operative myocardial infarction (p = 0.022) and red blood cell transfusion (p < 0.001). There was no difference in long-term survival between men and women on multivariate analysis (p = 0.413). Conclusion: Female gender is not associated with poorer short- or long-term outcomes after concomitant CABG and AVR surgery. Copyright (C) 2011 S. Karger AG, Basel
