摘要 目的探讨老年急性心肌梗死患者梗死早期恶性室性心律失常(MVA)的发生率、病死率及相关危险因素。方法选取天津市宁河县医院2009年1月至2013年6月老年急性心肌梗死患者420例,根据动态心电图结果将其分为MVA组和非MVA组,收集患者性别、年龄、糖尿病、高血压、高脂血症、心肌梗死病史、吸烟史、WBC、Hb、中性粒细胞、PLT计数、总胆固醇、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇、三酰甘油、血钾、血尿素氮、血肌酐、血糖、肌酸激酶及肌酸激酶同工酶、肌钙蛋白I、心功能Killip分级、校正的T波峰末间期、心率变异性、是否经直接冠状动脉介入(PCI)术开通梗死相关血管及超声心动图结果等指标,比较上述指标的差异性并进行Logistic回归分析。结果 420例老年急性心肌梗死患者共有152例(36.19%)发生MVA,其中,死于MVA者26例(17.11%),Logistic回归分析显示高龄、肌酸激酶同工酶及肌钙蛋白I升高、低血钾、心功能Killip分级较高、心率变异性减低、左心室射血分数减低是MVA的危险因素;行直接PCI术开通梗死相关血管是MVA的保护因素。结论老年急性心肌梗死患者MVA发病率及病死率较高,对具备以上MVA相关危险因素的患者应引起足够的临床重视。
