Popis: PURPOSE: Bypass surgery in patients undergoing cardiogenic shock caused by acute coronary syndrome is one of the most urgent and often performed cardiac operations. It remains unclear if patients gender independently influences the outcome. Literature reveals that females and males primarily differ from each other with regard to many important preoperative characteristics. Our objective was to compare the outcome and postoperative courses of both genders, using matched samples, eliminating these preoperative differences. METHODS: Between 2007 and 2015, 491 patients in cardiogenic shock underwent urgent bypass surgery in our institution. To assess the impact of gender on outcomes, we performed a propensity score matching to create two groups [males and females] which were matched for age, severity of shock, coronary artery disease morphology, and other comorbidities. Two groups were created: (1) 103 female and (2) 103 male patients. We analyzed the outcomes, complications and potential mortality predictors. RESULTS: Most of the patients had three-vessel disease (70.1%, n = 344) with proximal left anterior descending lesion (88%, n = 432). Our study showed no differences between female and male patients regarding choice of conduits, number of anastomosed vessels, and outcome. Acute kidney injury (AKI) occurred significantly more often in female patients and pericardial tamponade in their male counterparts. There were no differences regarding other major complications. CONCLUSION: Gender does not appear to influence long-term outcomes in the study sample. Female gender is an independent risk factor for postoperative AKI. Other complications occurred with comparable rates in both genders. Exertion tolerance in the follow-up period was similar between genders.
