【摘要】目的 研究急性非ST段抬高型心肌梗死(NSTE-AMI)者aVR导联抬高幅度，与冠状动脉造影(CAG)对比，判断其对左主干/三支病变(LM/3VD)诊断的指导作用。方法 对比106例aVR导联ST段抬高程度，结合CAG结果，研讨诊断LM/3VD的敏感性、特异性及相关性。结果 aVR导联ST段抬高是LM/3VD的独立预测因子(P<0.01)，aVR导联ST段抬高≥0.5mm预测LM/3VD的敏感性及特异性分别为76%、86%。ST段抬高≥1.0mm预测LM/3VD的敏感性及特异性分别为43%、96%，ST段抬高≥1.5mm预测LM/3VD的敏感性及特异性分别为18%、99%。结论 aVR导联ST段抬高是NSTE-AMI者LM/3VD非常有用的预测因子，特异性好。

【Abstract】 Objective To investigate effect of elevation in lead aVR for Left Main or 3-Vessal Disease(LM/3VD) in patients with Non-ST Segment Elevation Acute Coronary Syndrome(NSTE-ACS) by Comparing with Coronary angiography(CAG). Methods On admission ,the clinical factors of 106 patients, who underwent coronary angiography, ware evaluated. The elevation in lead aVR were measured on 12-lead electrocardiogram, by which to to evaluate sensitivity ,specificity and dependability in identifying LM/3VD. Results Elevation in lead aVR was independent predictors of LM/3VD,A ST-segment elevation in lead aVR of ≥0.5mm identified LM/3VD with sensitivity of 76%, specificity of 86%. A ST-segment elevation in lead aVR of ≥1.0mm identified LM/3VD with sensitivity of 43%, specificity of 96%, and A ST-segment elevation in lead aVR of ≥1.5mm identified LM/3VD with sensitivity of 18%, specificity of 99%. Conclusion ST-segment elevation in lead aVR is very useful independent predictors of LM/3VD in patients with Non-ST Segment Elevation Acute Coronary Syndromes.
