目的: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。方法:选择我院收治的150例急性前壁 STEMI 患者,根据3个月的左室射血分数(3m LVEF),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。结果:与心功能正常组比较,心功能不良组ΣST、ΣQ、STm、Qm、CKm、CK-MBm、cTnTm,左室舒张末期内径(LVEDd),3mLVEDd 均显著增大,ΣR、LVEF、3mLVEF 均显著减小(P <0.05或<0.01);Spearman 相关分析显示,ΣST、ΣQ、STm、Qm、CKm、CK-MBm、cTnTm 与3m LVEDd 均呈正相关(r =0.18~0.63,P <0.05或<0.01),与3m LVEF均呈负相关(r =-0.88~-0.42,P 均<0.01)。ΣR 与 LVEDd,3m LVEDd 呈负相关(r =-0.46、-0.51,P<0.01),与 LVEF,3m LVEF 呈正相关(r =0.81、0.71,P 均<0.01)。结论:前壁 STEMI 患者的 ST 段抬高越多,Q 波越大,R 波越小,心肌酶峰越高,患者短期的心功能越差。

Objective:To explore the correlation among ECG indexes,myocardial enzyme peak and short term cardi-ac function in patients with acute anterior ST elevation myocardial infarction (STEMI).Methods:A total of 150 pa-tients with acute anterior STEMI were selected from our hospital.According to left ventricular ejection fraction af-ter three months (3m LVEF),they were divided into cardiac dysfunction group (n=78,LVEF<50%)and normal cardiac function group (n= 72,LVEF≥ 50%).Following indexes were compared between two groups,including sum of ST elevation extent (ΣST),R wave (ΣR),Q wave (ΣQ),maximum value of ST elevation (STm)and Q wave (Qm)etc.on infarct related leads,and peak value of creatine kinase (CKm),CK isoenzyme (CK-MBm)and cardiac troponin T (cTnTm)etc.Results:Compared with normal cardiac function group,there were significant rise in ΣST,ΣQ,STm,Qm,CKm,CK-MBm,cTnTm,left ventricular end-diastolic diameter (LVEDd),3mLVEDd and significant reduction in ΣR and LVEF,3mLVEF in cardiac dysfunction group,P <0.05 or <0.01;Spearman correlation analysis indicated that ΣST,ΣQ,STm,Qm,CKm,CK-MBm and cTnTm were positively correlated with 3m LVEDd (r =0.18~0.63,P <0.05 or <0.01),and inversely correlated with 3m LVEF (r =-0.88~-0.42, P <0.01 all).ΣR was inversely correlated with LVEDd and 3m LVEDd (r =-0.46、-0.51,P <0.01 both),and positively correlated with LVEF and 3m LVEF (r =0.81,0.71,P <0.01 both).Conclusion:In patients with ante-rior STEMI,the higher ST elevation,the higher Q wave,the lower R wave,the higher myocardial enzyme peak is, the poorer short term cardiac function is.
