摘要 目的回顾性分析北京汉族老年冠心病人群急性心梗(acute myocardial infarction AMI)发病与乙醛脱氢酶-2(aldehyde dehydmgenase-2 ALDH-2)基因G487A多态性的相关性,为进一步预防、降低老年急性心肌梗死发生率提供参考依据。方法选择2009年5月到2010年12月于北京第二炮兵总医院心内科行冠状动脉造影检查异常且住院资料完整的北京市汉族60岁及以上患者162例,分为A、B两组;A组54例,为急性心肌梗死(acute myocardial infarction AMI)组;B组108例,为稳定性心绞痛(stable angina pectoris SAP)组;冠脉造影阴性组34例,为C组。全部入选患者分别详细记录病史及查体情况,于次日晨空腹采集静脉血,检测ALDH-2基因型(野生纯合型记为GG,突变型杂合型为GA,突变纯和型为AA)、血常规以及生化全套等。结果三组分别两两相比,A组与B组相比;A组与C组相比,ALDH-2突变基因型明显增多,差别有显著统计学差异(P<0.05)。B组与C组相比,ALDH-2突变基因型有减少趋势,但两组间未见统计学差异(P>0.05),见表1所示。结论 ALDH-2突变基因型是北京汉族老年冠心病患者发生急性心肌梗死的危险因素之一。
