The main goal of our study was to evaluate possible perioperative risk factors for occurrence of atrial fibrillation in the postoperative period in patients after CABG operations. The study included 140 patients after CABG, divided into two groups - Group I - 64 patients with new onset of POAF and Group II - 76 patients without postoperative atrial fibrillation occurrence. In both groups possible risk factors for atrial fibrillation onset (preoperative and postoperative) were analyzed.Results showed that we can predict new onset of atrial fibrillation after CABG if the following preoperative factors are present - low ejection fraction (less than 40%), LAd > 40mm, higher body mass index (BMI over 30), presence of COPD and older age. Important perioperative factors for onset of atrial fibrillation in our study were longer extracorporeal circulation, increased dose/number of inotropic drugs, blood transfusion and elevated WBC count postoperatively.
本研究的主要目的是评估 CABG 术后患者心房颤动（POAF）发生的围手术期相关风险因素。研究共纳入 140 例行 CABG 的患者，分为两组：I 组（64 例新发 POAF）和 II 组（76 例未发生术后房颤）。对两组患者的所有可能的房颤发生相关的术前和术后风险因素进行了分析。结果显示，如果存在以下术前因素，则提示 CABG 术后新发房颤的可能性较高：射血分数（EF）较低（<40%）、左房内径（LAd）较大（>40mm）、体质量指数（BMI）较高（>30）、COPD 及年龄较大。本研究中，心房颤动发生的重要围手术期因素包括体外循环时间延长、正性肌力药物剂量/数量增加、输血和术后白细胞计数升高。
