摘　　要：目的判断aVR导联ST段压低预测急性下壁ST段抬高型心肌梗死(STEMI)患者右冠状动脉(RCA)或左冠状动脉回旋支(LCX)闭塞的价值。方法入选212例急性下壁STEMI患者,完成冠状动脉造影,术前记录标准12导联心电图,根据冠状动脉造影结果分析aVR导联ST段压低诊断RCA或LCX闭塞的敏感度、特异度。结果aVR导联ST段压低预测急性下壁STEMI患者梗死相关血管LCX的敏感度和特异度分别为55%和86%,而预测RCA的敏感度和特异度仅为14%和45%。结论aVR导联ST段压低是下壁STEMI患者LCX闭塞的预测因素。Objective To study if ST-segment depression in aVR in patients with acute inferior wall infarction can predict occlusion in right coronary artery（RCA）or left circumflex（LCX）. Methods Two hundreds and twelve consecutive patients with inferior wall STEMI underwent urgent coronary angiography. Clinical and angiographic findings were compared between patients with and without aVR depression ≥ 0.1 mV. Results The sensitivity and specificity of aVR ST-segment depression as a predictor of LCX occlusion were 55% and 86%, while the forecast sensitivity and specificity of RCA was only 14% and 45%. Conclusions ST-segment depression in aVR in patients with acute inferior wall STEMI might predict LCX occlusion.
