目的：探究前壁ST段抬高型心肌梗死（ASTEMI）患者的心电图改变与多支冠状动脉病变的相关关系及其对多支冠状动脉病变的预测价值。方法选择 ASTEMI 患者230例，用回顾性分析的方法对其心电图的改变与冠状动脉血管造影资料进行分析。结果ASTEMI 患者的 aVL 导联、V6导联 ST 段压低并伴下壁导联镜像性改变与冠状动脉血管造影显示为多支血管病变（MVD）相关（P 均＜0．01）；当对所有 ASTEMI 患者进行分析时，若患者 aVL 导联、V4导联、V5导联、V6导联的ST 段出现压低，则与冠状动脉血管造影显示为 MVD 相关（P 均＜0．01）。结论对于 ASTEMI 并伴有下壁导联镜像性改变的患者，其前侧壁导联 ST 的压低与冠状动脉血管造影显示为 MVD 密切相关。

Objective To analyze the correlation between electrocardiogram (ECG)variations and multivessel disease (MVD),and evaluate ECG changes in predicting the risk of MVD in patients diagnosed with anterior ST elevation myocardial infarction (ASTEMI).Methods In this study,230 patients diagnosed with ASTEMI were recruited.ECG findings and imaging data of coronary artery were retrospectively analyzed. Results In the ASTEMI patients,the ST-segment depression in aVL and V6 leads complicated with reciprocal changes in the inferior leads were significantly correlated with the incidence of MVD assessed by coronary angi-ography (all P <0.01).The ST-segment depression in aVL,V4 ,V5 and V6 leads were remarkably associated with the presence of MVD assessed by coronary angiography (all P <0.01).Conclusion For ASTEMI pa-tients with reciprocal changes in the inferior wall leads,ST-segment depression in the anterolateral leads is closely related to the incidence of MVD reflected by coronary angiography.
