摘要
目的探讨前壁急性心肌梗死(AMI)aVR导联ST段抬高对冠状动脉左主干及左前降支近段病变的诊断及预后价值。方法将61例前壁AMI者的心电图和冠状动脉造影(CAG)及临床资料进行对比分析,根据aVR导联有无ST段变化分为抬高组(A组)及ST段无抬高组(B组)。结果①梗死相关血管为左主干病变的A组及B组分别为5例(19.2%)及1例(2.8%),两组统计有显著性差异(P<0.01)。②梗死相关血管为左前降支近段病变的A组及B组分别为20例(76.9%)及5例(14.2%)两组统计有显著性差异(P<0.01)。③发生心脏事件的A组及B组分别为10例(37.1%)、4例(11.4%),两组统计有显著性差异(P<0.01)。结论前壁AMIaVR导联ST段抬高对诊断左主干、左前降支近段病变及预后有很好的预测价值。
Objective To investigate the value of ST segment elevation of aVR lead in the diagnoses and prognosis of pathological changes of left main and proximal left anterior descending coronary artery in acute myocardial infarction. Methods We restrospctively analyzed electrocardiogram and clinical angiography in 61 patients with anterior wall acute myocardial infarction and divide them into elevation group and no elevation group according to the ST segment changes of aVR Lead . Results ①There was significant difference in the patients whose infarct - related vessel was left main coronary artery between the elevation group（5 cases, 19.2% ） and no elevation group（1 case, 2.8% ） （P 〈0.01 ）. ②The patients whose infarct - related vessel was proximal left anterior descending coronary artery in elevation group, 20 cases （76.9%） were significantly more than that of non elevation group, 5 cases （ 14.2% ） （ P 〈 0.01 ）. The cases with heart incident in elevation group, 10 cases （37.1%） were significantly more than that of no elevation group, 4 eases （11.4%） （P 〈0.01 ）. Conclusion ST segment elevation in lead aVR are indicators of predicting pathological changes of left main and proximal left anterior descending coronary artery and the prognosis of acute anterior myocardial infarction.
