冠状动脉旁路移植术后发生心房颤动的相关因素分析

Post Coronary Artery Bypass Grafting Atrial Fibrillation

目的：分析国人冠状动脉旁路移植（ＣＡＢＧ）术后心房颤动（ＡＦ）的高危因素。 方法：回顾我院近３ 年在体外循环下进行ＣＡＢＧ术患者６８６ 例，对可能与术后ＡＦ发生有关的诸因素进行卡方检验和Ｌｏｇｉｓｔｉｃ多因素回归分析，以找出与ＣＡＢＧ术后ＡＦ发生相关的高危因素。 结果：６８６例患者中，１４０ 例（２０．４％ ）并发了ＣＡＢＧ术后ＡＦ。ＡＦ的发生与年龄，术前ＡＦ史及术前心房早搏关系密切（Ｌｏｇｉｓｔｉｃ回归Ｐ＝ ０．００３，０．００１，０．０４６）。而与性别，心肌梗塞，体外循环时间，阻断时间，术前术后射血分数等诸因素无关（卡方检验及Ｌｏｇｉｓｔｉｃ Ｐ＞ ０．０５）。 结论：ＡＦ同样是国人ＣＡＢＧ术后常见并发症。高龄。

Objective:To assess the clinical risk factors of post coronary artery bypass grafting(CABG)atrial fibrillation(AF). Methods:We reviewed 686 cases of CABG,they were operated in our hospital in recent three years and used X 2 and multiple stepwise logistic analysis regression to assess clinical risk factors. Results:One hundred and fourty cases(20 4%)associated with the AF.Age,history of AF and atrial extrasystole were the clinical risk factors,while sex,myocardial infarction,duration of cardiopulmonary bypass,clamp time and pre or post operation ejection fraction etc were not. Conclusion:Post CABG AF was a common complication.The aged,history of AF and atrial extrasystole were the clinical risk factors of the AF.
