探讨心电图和心肌酶峰与急性前壁ST段抬高型心肌梗死(STEMI)患者短期心功能的相关性。
ToexplorethecorrelationamongECGindexes,myocardialenzymepeakandshorttermcardiacfunctioninpatientswithacuteanteriorSTelevationmyocardialinfarction(STEMI).选择我院收治的例急性前壁STEMI患者,根据3个月的左室射血分数(3mLVEF),分为心功能不良组(LVEF<50%,78例)和心功能正常组(LVEF≥50%,72例)。比较两组患者梗死相关导联心电图的ST段抬高幅度之和(ΣST)、R波振幅之和(ΣR)、Q波之和(ΣQ)、ST段抬高最大值(STm)、Q波最大值(Qm),以及CK的峰值(CKm)、CK-MB的峰值(CK-MBm)、cTnT的峰值(cTnTm)等指标。
