急性心肌梗死并室性心动过速/心室颤动的影响因素分析

Factors influencing ventricular tachycardia/ventricular fibrillation complicated with acute myocardial infarction

目的:分析急性心肌梗死(acute myocardial infarction,AMI)患者并发室性心动过速(ventriculartachycardia,VT)/心室颤动(ventricular fibrillation,VF)的影响因素。方法:将安徽医科大学第一附属医院收治的453例AMI患者分为VT/VF组和无VT/VF组,对两组进行比较分析发生VT/VF的影响因素。结果:单因素分析示,VT/VF组与无VT/VF组在诸多方面差异有显著性。经多因素Logistic回归分析显示,高级别的Killip分级、血钾离子水平异常以及广泛前壁心肌梗死是影响患者发生VT/VF的独立危险因素,β-受体阻滞剂是保护因素。结论:VT/VF是AMI患者的严重并发症,高级别的Killip分级、血钾水平异常以及广泛前壁心肌梗死是影响患者发生VT/VF的独立危险因素,而β-受体阻滞剂是保护因素。

Objective To analyze the influential factors of ventricular tachycardia/ventrieular fibrillation （VT/VF） in patients with acute myocardial infarction （AMI）. Methods Four hundread and fifty three patients with AMI were divided into VT/VF group and non-VT/VF group. The influential factors of VT/VF were analyzed in the two groups. Results Multivariable logistic regression analysis indicated that higher Killip class, abnormality of serum potassium, and extensive anterior infarction were the independent risk factors, while β-blocker was the protective one. Conclusions VT/VF is one of the most serious complications of AMI. Higher Killip class, abnormality of serum potassium, and extensive anterior infarction were the independent risk factors, whileβ-blocker was the protective one.
