扩张型心肌病患者发生电风暴的危险因素

The risk factors of dilated cardiomyopathy

目的了解扩张型心肌病(扩心病)患者电风暴的发生率,并探讨其发生电风暴的相关危险因素。方法观察53例住院的扩心病患者,通过心电监护或24h动态心电图识别电风暴,根据是否发生电风暴进行分组,采用单因素和多因素分析,发现危险因素。结果 34%患者在住院期间发生电风暴,房颤病史(OR:2.2,95%CI:1.2-5.0;p=0.015)和左室舒张末容积增加(OR:1.4,95%CI:1.13-1.72;p=0.041)是电风暴发生的独立危险因素。结论房颤病史和左室舒张末容积增加是扩心病发生电风暴的危险因素,结合这些指标,可以对扩心病患者发生电风暴进行危险分层。

Objective To study the incidence of electrical storm（ES） in patients with dilated cardiomyopathy（DCM） and to explore risk factors associated with the occurrence of ES.Methods Fifty-three cases DCM were included in this study.ES was identified through Holter monitoring or 24-hour ECG,and 53 cases were grouped depending on ES occurred or not.Risk factors were identified with univariate and multivariate analysis.Results ES occurred in 18 patients.History of atrial fibrillation（AF）（OR2.2,95% CI 1.2-5.0;p= 0.015） and increase of left ventricular end diastolic volume（LVEDV）（OR 1.4,95% CI 1.13-1.72;p=0.041） were identified as independent risk factors for ES in DCM patients.Conclusions History of AF and LVEDV increased the incidence of ES.Combined with these indicators,the risk of ES occurrence in DCM patients can be graded.
