Abstract

Introduction Many etiological factors affect the occurrence of atrial fibrillation after coronary artery bypass grafting. In this study, the relationship between cardiopulmonary bypass and cross-clamping times and the development of postoperative atrial fibrillation was examined. Methods All patients who underwent isolated coronary artery bypass grafting with the same surgical team in our clinic between September 2018 and December 2019 were prospectively included in the study, and their perioperative data were recorded. Results One hundred and three patients who met the specified criteria were included in the study. The median age was 62 (interquartile range: 54-71) years, and 82 (79.6%) were male. The patients were divided into two groups: those who developed atrial fibrillation and those who did not. Atrial fibrillation developed in 25 of 103 patients (24.3%). All patients underwent isolated coronary artery bypass grafting under standard cardiopulmonary bypass. The median duration of cardiopulmonary bypass was 72 (interquartile range: 63-97) minutes in those with atrial fibrillation and 82 (61-98) minutes in those without it, and there was no statistical difference (P=0.717). The median cross-clamping time was 40 (32.5-48) minutes in those with atrial fibrillation and 39.5 (30-46) minutes in those without it. Statistically, the relationship between cross-clamping time and atrial fibrillation was not significant (P=0.625). Conclusion Our study found no significant relationship between cardiopulmonary bypass and cross-clamping times and the incidence of postoperative atrial fibrillation. However, we believe that there is a need for large-scale and multicenter clinical studies on the subject.
单中心前瞻性临床研究主动脉交叉阻断时间对孤立性冠状动脉旁路移植术后心房颤动发展的影响
引言冠状动脉搭桥术后心房颤动的发生受到多种病因的影响。在本研究中,研究了体外循环和交叉夹闭时间与术后心房颤动发展的关系。方法前瞻性纳入2018年9月至2019年12月期间在我们诊所由同一手术团队接受孤立性冠状动脉搭桥术的所有患者,并记录他们的围手术期数据。结果103名符合指定标准的患者被纳入研究。中位年龄为62岁(四分位间距:54-71),82岁(79.6%)为男性。患者被分为两组:发生心房颤动的患者和未发生心房颤动者。103例患者中有25例(24.3%)发生心房颤动。所有患者都在标准体外循环下接受了孤立的冠状动脉搭桥术。心肺转流的中位持续时间有心房颤动的患者为72分钟(四分位间距:63-97),无心房颤动的为82分钟(61-98),无统计学差异(P=0.717)。心房颤动患者的中位交叉阻断时间为40分钟(32.5-48),非心房颤动患者为39.5分钟(30-46),交叉夹闭时间与心房颤动的关系不显著(P=0.625)。结论体外循环和交叉夹闭次数与术后心房颤动的发生率没有显著关系。然而,我们认为有必要对该主题进行大规模和多中心的临床研究。
