Abstract :Life expectancy is improving worldwide. The number of septuagenarian and older patients requiring open heart surgery is increasing. The aim of this study was to determine the risk factors associated with in-hospital mortality and poor outcomes in septuagenarian and elderly patients undergoing various open heart surgery procedures in regards of gender. We retrospectively collected the medical records of 104 patients aged >70 years who underwent open heart surgery between 2018 and 2024. Preoperative comorbidities, cross-clamp time, cardiopulmonary bypass time, postoperative bleeding, acute kidney insufficiency, arrhythmia, stroke, low cardiac output, sepsis, duration of mechanical ventilation, length of intensive care unit and hospital stays, mortality were evaluated. The mean age was 74.27 ± 4.80 years; that of women was 74.9 ± 4.9 years, and men was 73.7 ± 4.6 years. Preoperative myocardial infarction was more frequent in men. Coronary artery bypass grafting and thoracic aorta surgery were more frequent in men and women, respectively. Women were more affected by postoperative atrial fibrillation, more frequently required extended mechanical ventilatory support, and had longer ICU stays. Hosmer–Lemeshow and Omnibus tests revealed that age of >76 years, cardiopulmonary bypass time longer than 200 minutes, revision for bleeding, low cardiac output were significant predictors of in-hospital mortality. Despite increased costs and longer hospital stays, cardiac operations can be successfully performed in septuagenarian and elderly patients.
