BACKGROUND: This study evaluates the impact of gender in dialysis-dependent patients undergoing cardiac surgery. METHODS: We retrospectively identified 204 dialysis-dependent patients (68.6% male, aged 66.6 ± 9.9 years) with end-stage renal disease undergoing cardiac surgery and compared them to a propensity-score-pair-matched control collective. RESULTS: A 30-day mortality was 13.2% (14/106) for coronary artery bypass grafting (CABG), 19.3% (6/31) for aortic valve replacement (AVR), and 23.8% (16/67) for combined procedures. Postoperative chest tube output was significantly higher in men (1,007 ± 946 mL) versus women (687 ± 598 mL, p = 0.014). Compared with a propensity-score-pair-matched control collective of 204 patients, we identified significant differences in terms of 30-day mortality: overall mortality revealed 17.6 versus 4.6% (p = 0.0001), 13.2 versus 3.4% (p = 0.014) for CABG, 19.3 versus 0% (p = 0.051) for AVR, and 23.8 versus 9.1% (p = 0.02) for combined procedures. CONCLUSION: Multivariate analysis identified preoperative myocardial infarction, prolonged extracorporeal circulation time, operation time, and surgical reexploration as independent predictors of 30-day mortality. There was a higher occurrence of bleeding complications in men that remained significant even after correction for body surface area. Georg Thieme Verlag KG Stuttgart · New York.
