Abstract

Objective: To determine the incidence of postoperative atrial fibrillation in patients undergoing on-pump and off-pump coronary artery bypass grafting.

Methods: A retrospective study with analysis of 230 medical records between January 2011 and October 2013 was conducted.

Results: Fifty-six (24.3%) out of the 230 patients were female. The average age of patients undergoing on-pump coronary artery bypass grafting was 59.91±8.62 years old, and off-pump was 57.16±9.01 years old (P=0.0213). The average EuroSCORE for the on-pump group was 3.37%±3.08% and for the off-pump group was 3.13%±3% (P=0.5468). Eighteen (13.43%) patients who underwent off-pump coronary artery bypass grafting developed postoperative atrial fibrillation, whereas for the onpump group, 19 (19.79%) developed this arrhythmia, with no significant difference between the groups (P=0.1955).

Conclusion: Off-pump coronary artery bypass grafting did not reduce the incidence of atrial fibrillation in the postoperative period. Important predictors of risk for the development of this arrhythmia were identified as: patients older than 70 years old and presence of atrial fibrillation in perioperative period in both groups, and non-use of beta-blockers drugs postoperatively in the on-pump group.

接受泵上和泵下冠状动脉旁路移植术的患者术后心房颤动的发生率。

目的确定接受体外循环冠状动脉旁路移植术和体外循环冠状动脉旁路移植术的患者术后心房颤动的发生率：方法：对 2011 年 1 月至 2013 年 10 月期间的 230 份病历进行回顾性分析：230名患者中有56名（24.3%）为女性。接受体外循环冠状动脉搭桥术的患者平均年龄为（59.91±8.62）岁，体外循环冠状动脉搭桥术患者平均年龄为（57.16±9.01）岁（P=0.0213）。泵上组的平均EuroSCORE为（3.37%±3.08%），泵下组的平均EuroSCORE为（3.13%±3%）（P=0.5468）。18例（13.43%）接受非体外循环冠状动脉旁路移植术的患者术后出现心房颤动，而体外循环组有19例（19.79%）患者出现这种心律失常，组间差异无显著性（P=0.1955）：结论：非泵冠状动脉旁路移植术并未降低术后心房颤动的发生率。两组患者中，年龄超过70岁的患者和围手术期存在心房颤动的患者，以及在泵组术后未使用β-受体阻滞剂药物的患者，都是导致心律失常发生的重要风险预测因素。
