目的评价运动试验阳性(Duke评分≤-11分)患者中aVR及V1导联ST段变化对于左主干病变的预测价值.方法回顾性分析了 96例(Duke评分≤-11分)运动试验阳性患者,在运动试验中aVR及V1导联ST段变化,并与冠状动脉造影(CAG)结果比较.结果单纯aVR导联ST段抬高,在诊断左主干病变的敏感性为85.5%,特异性47.1%,准确率62.5%;而aVR及V1导联ST段均抬高,且STaVR/STV1＞1时,在诊断左主干病变的敏感性为82.1%,特异性83.8%,准确率83.3%.结论在运动试验中aVR和V1导联ST段抬高(STaVR/STV1＞1),对左主干病变有较高的预测价值.

Objective To evaluate the value of lead aVR and V1 on the exercise electrocardiogram for the detection of left main coronary artery disease (LMCAS) in patients with the positive EET result ( Duke scores ≤ - 11 ). Methods Ninty-six patients with Duke score ≤ - 11 were retrospectively screened for presence of ST-segment elevation in lead aVR and lead V1. Coronary arteriography (CAG) results were compared among different groups. Results Twenty-eight out of 96 were diagnosed as LMCAS. 24 out of 60 with ST-segment elevation in lead aVR and 26 out of 34 with ST-segment elevation in lead aVR and V1 ( STaVR/STV1＞ 1 )were found to have LMCAS. Isolated exercise-induced ST elevation in lead aVR had a sensitivity of 85. 5, a specificity of 47. 1% and an accuracy of 62. 5% in predicting LMCAS; ST-segment elevation in lead aVR and V1 ( STaVR/STV1 ＞ 1 ) had a sensitivity of 82. 1% ,a specificity of 83. 8% and an accuracy of 83.3% in predicting LMCAS. Conclusion ST-segment elevation in lead aVR and V1(STaVR/STV1 ＞ 1) criteria has a high value in predicting LMCAS.
