摘要
目的探究心脏瓣膜置换术后室性心律失常发生的独立危险因素。方法回顾性分析2016年2月～2017年2月在我院进行心脏瓣膜置换术的216例患者的临床资料。依据术后是否发生室性心律失常将患者分为室性心律失常组（A组，n=24）和非室性心律失常组（B组，n=192）。记录脏瓣膜置换术后室性心律失常发生的相关因素，并进行Logistic多元回归分析。结果Logistic多元回归分析结果显示，病程≥15年、心功能Ⅳ级、重度三尖瓣关闭不全、主动脉阻断时间〉90min、体外循环时间〉150min、低心排出量综合征是心脏瓣膜置换术患者术后发生室性心律失常的独立危险因素（P〈0．05）。结论心脏瓣膜置换术后室性心律失常的发生与病程、心功能分级、重度三尖瓣关闭不全、主动脉阻断时间、体外循环时间、低心排出量综合征等因素密切相关，临床上应予以重视并采取适当的预防措施。
Objective To explore independent risk factors of ventricular arrhythmia after heart valve replacement. Methods Clinical data of 216 patients with heart valve replacement in our hospital from Feb. 2016 to Feb. 2017 were analyzed retrospectively. Patients were divided into ventricular arrhythmia group （group A, n = 24） and non -ventricular arrhythmia group（ group B, n = 192 ） according to whether postoperative ventricular arrhythmia occurred or not. Related factors affecting the occurrence of ventricular arrhythmia after heart valve replacement were recorded and Logistic multivariate regression analysis was performed. Results Logistic multivariate regression analysis showed that course of disease ≥ 15 years, cardiac function grade IV, severe tricuspid insufficiency, aortic crossclamp time 〉 90 min, cardiopulmonary bypass time 〉 150 min and low cardiac output syndrome were independent risk factors for ventricular arrhythmia after heart valve replacement （P 〈 0.05 ）. Conclusion The occurrence of ventricular arrhythmia after heart valve replacement are closely related to course of disease, cardiac function grade, tricuspid insufficiency, aortic crossclamp time, cardiopulmonary bypass time, low cardiac output syndrome and other factors, which should be paid attention and taken appropriate precautions in clinical application.
