背景：老年患者和患有多种并发疾病的患者如今已经可以进行心脏外科手术，这与术后并发症的发生率较高有关。目的：本研究的目的是对可能导致心脏手术后发生心脏事件的围手术期因素进行回顾性分析。方法：收集并分析552例心脏外科门诊患者的数据。检查了有关病史，先前治疗，实验室结果，其他检查结果，手术和住院时间的数据。结果：在研究的552名患者中，有49.5％观察到心脏并发症。在心脏并发症中，最常见的是室上性心动过速（30.1％）和房颤（27.4％）。5.25％的患者发生术后心动过缓，其中一半需要临时起搏。结论：心脏外科手术后发生心脏并发症的风险主要取决于患者的年龄，EuroSCORE Logistic（ESL）评分，左心室射血分数，心肌肥大，阵发性房颤的存在和肾病并发症的发生。移除主动脉夹钳后必须进行多于一次的心脏除颤，这有利于术后早期心动过缓。考虑到这项研究的结果，至少持续再灌注直至主动脉交叉钳夹时间的1/3不会给患者带来额外的好处。心脏外科手术后发生心脏并发症的风险主要取决于患者的年龄，EuroSCORE Logistic（ESL）评分，左心室射血分数，心肌肥大，阵发性房颤的存在以及肾病并发症的发生。移除主动脉夹钳后必须进行多于一次的心脏除颤，这有利于术后早期心动过缓。考虑到这项研究的结果，至少持续再灌注直至主动脉交叉钳夹时间的1/3不会给患者带来额外的好处。心脏外科手术后发生心脏并发症的风险主要取决于患者的年龄，EuroSCORE Logistic（ESL）评分，左心室射血分数，心肌肥大，阵发性房颤的存在以及肾病并发症的发生。移除主动脉夹钳后必须进行多于一次的心脏除颤，这有利于术后早期心动过缓。考虑到这项研究的结果，至少持续再灌注直至主动脉交叉钳夹时间的1/3不会给患者带来额外的好处。移除主动脉夹钳后必须进行多于一次的心脏除颤，这有利于术后早期心动过缓。考虑到这项研究的结果，至少持续再灌注直至主动脉交叉钳夹时间的1/3不会给患者带来额外的好处。移除主动脉夹钳后必须进行多于一次的心脏除颤，这有利于术后早期心动过缓。考虑到这项研究的结果，至少持续再灌注直至主动脉交叉钳夹时间的1/3不会给患者带来额外的好处。
Background: Elderly patients and those with multiple concomitant disorders are nowadays qualified for cardiac surgery procedures, which is related to higher incidence of the postoperative complications. Aim: The aim of this study was a retrospective analysis of the perioperative factors potentially contributing to occurrence of cardiac incidents after cardiac surgery procedures. Methods: Data of 552 patients of the cardiac surgery clinic were collected and analyzed. Data concerning medical history, previous treatment, laboratory results, additional tests results, operation and hospitalization period were examined. Results: In the study population of 552 patients, cardiac complications were observed in 49.5% of them. Among cardiac complications, the most frequent were supraventricular tachycardia (30.1%) and atrial fibrillation (27.4%). Postoperative bradycardia occurred in 5.25% patients, half of whom required temporary cardiac pacing. Conclusions: The risk of incidence of cardiac complications after cardiac surgery procedures depends mostly on patient’s age, EuroSCORE Logistic (ESL) score, left ventricular ejection fraction, myocardial hypertrophy, presence of paroxysmal AF and coincidence of nephrological complications. The necessity of performing more than one heart defibrillation after removing aortic cross-clamp favors early postoperative bradycardia. Considering the outcomes of this study, continuing reperfusion at least until 1/3 of the aortic cross-clamp time brings no additional benefits to the patients.
