目的:探讨老年ST段抬高型心肌梗死患者发生恶性室性心律失常的相关危险因素。方法:对150例老年ST段抬高型心肌梗死患者的临床资料进行回顾性分析,根据有无恶性室性心律失常(MVA)将其分为对照组(非MVA)和观察组(MVA),对两组的临床资料及指标进行比较,并进行Logistic回归分析。结果:性别、年龄、吸烟史、高血压史、糖尿病史、心绞痛史、血糖、糖化血红蛋白(Hb A1c)、血钾、肌酐(Cr)、BUN、甘油三脂(TG)、总胆固醇(TC)、高密度脂蛋白(HDL)、低密度脂蛋白(LDL)及病变类型与老年ST段抬高型心肌梗死患者发生MVA的发生无关,Killip分级、Cr和LDL与MVA的发生有关,且Killip分级和Cr水平是发生MVA的独立危险因素。结论:Killip分级和Cr水平是诱发老年ST段抬高型心肌梗死后MVA的独立危险因素。
Objective: To investigate the risk factors of malignant ventricular arrhythmia in elderly patients with ST-segment elevation myocardial infarction. Methods: The clinical data of 150 aged patients with ST segment elevation myocardial infarction were retrospectively analyzed. According to the presence or absence of malignant ventricular arrhythmias (MVA), they were divided into control group (MVA) and observation group (MVA) The clinical data and indexes of the two groups were compared and analyzed by Logistic regression. Results: Hb A1c, serum potassium, creatinine (Cr), BUN, triglyceride (TG) and total cholesterol (TC) , High density lipoprotein (HDL), low density lipoprotein (LDL) and pathological types were not associated with the occurrence of MVA in elderly patients with ST segment elevation myocardial infarction. Killip grade, Cr and LDL were associated with the occurrence of MVA, And Cr levels are independent risk factors for MVA. Conclusion: Killip grading and Cr levels are independent risk factors of inducing MVA in elderly patients with ST-segment elevation myocardial infarction.
