aVR导联ST段抬高对急性心肌梗死预后的价值

目的探讨心电图aVR导联ST段抬高对急性前壁心肌梗死患者预后的价值。方法首次入院急性前壁心肌梗死患者57例，对其心电图和冠状动脉造影及临床资料进行对比分析。根据心电图aVR导联ST段变化分为抬高组、无偏移组。结果梗死相关血管为左主干病变的ST段抬高组、ST段无偏移组分别为5例（21．7％）、1例（2．9％），两组统计有显著性差异（p〈0．01）；病变范围为多支病变ST段抬高组、ST段无偏移组分别为10例（43．4％）、8例（23．5％），两组统计有显著性差异（p〈0．05）；发生心脏事件ST段抬高组、ST段无偏移组分别为8例（34.8％）、3例（8．8％），两组有显著性差异（p〈0．01）。结论aVR导联ST段抬高对预测急性前壁心肌梗死患者的预后有重要的价值，应高度重视。

Value of ST segment elevation of aVR lead in patients with acute anterior wall myocardial infarction.

Objective To evalue the value of ST segment elevation of aVR lead in patients with acute anterior wall myocardial infarction. Methods The electrocardiogram and coronary angiographic findings were analyzed in 57 patients with fist episode of anterior wall acute myocardial infarction , divided into elevation group and no drift group according to the ST segment changes of aVR lead. Results The patients whose infarct-related vessel was left main coronary artery were significantly more in elevation group (5 cases, 21.7%) than in no drift group(1 cases ,2.9%) (p<0.01) .The cases with multi-vessel lesions in elevation group (10 cases ,43.4%))were significantly more than in no drift group ( 8 cases ,23.5%) (p<0.01). The cases with heart incident in elevation group (8 cases ,34.8%) were significantly more than in no drift group ( 3 cases ,8.8%) (p<0.01). Conclusions ST segment elevation of aVR lead in patients with acute anterior wall myocardial infarction is useful for predicting prognosis of acute anterior wall myocardial infarction. it is important to treat .
