摘要 目的探讨平均血小板体积(MPV)与急性非ST抬高型心肌梗死(NSTEMI)、急性ST抬高型心肌梗死(STEMI)患者梗死相关动脉(IRA)分布的关系。方法选取2009年1月~2011年7月入院的NSTEMI、STEMI患者各120例,分别为NSTEMI组和STEMI组。均行冠脉造影检查确定IRA分布,行血常规检查测定MPV。结果NSTEMI组IRA为左冠状动脉回旋支(LCX)者51例、前降支(LAD)43例、右冠状动脉(RCA)26例,STEMI组分别为63、14、43例。NSTEMI组IRA为LCX者的MPV为(10.1±1.6)f L,为LAD者的MPV为(8.9±1.5)f L,为RCA者的MPV为(9.7±1.7)f L,IRA为LAD者的MPV显著低于IRA为LCX、RCA者(P均〈0.05)。当MPV取9.1 f L时,其预测NSTEMI患者IRA为LAD的灵敏度为55.8%,特异度为70.1%。STEMI组IRA为LCX者的MPV为(9.2±1.3)f L,为LAD者的MPV为(9.3±1.6)f L,为RCA者的MPV为(9.5±1.5)f L,三者MPV差异无统计学意义。结论 NSTEMI和STEMI患者IRA分布不同。MPV与NSTEMI患者IRA分布有关,与STEMI患者IRA分布无关。MPV是NSTEMI患者IRA为LAD的预测指标。
