目的探讨心电图ST<aVR>抬高对急性冠状动脉综合征预后评估的价值. 方法回顾性分析68例急性冠状动脉综合征患者的心电图和冠状动脉造影资料、临床资料.根据ST<aVR>抬高是否≥0.05mV分为抬高组(n=23)和非抬高组(n=45). 结果病变血管涉及左主干和左前降支近段的分别为抬高组13例(56.5%)和非抬高组1例(2.2%).病变范围为多支病变的分别为9例(39.1%)和8例(17.8%),发生心脏事件分别为7例(30.4%)和4例(8.9%),两组差异均有非常显著性意义(P<0.01). 结论急性冠状动脉综合征患者ST<aVR>抬高提示左主干和左前降支近段病变、多支病变的可能,对判断预后有参考价值.

Objective To evaluate prognostic value of ST segment elevation in lead aVR in patients with acute coro-nary syndrome(ACS). Methods 68 patients with ACS were divided into elevation group(n=23) and non-elevation group (n=45) according to whether ST segment elevation in lead aVR ≥0.05mV or not and their coronary angiography results were analyzed. Results The cases with lesions in left main coronary artery and proximal left anterior descending coro-nary artery, multi-vessel lesions, and cardiac events were significantly more in elevation group (56.5%,39.1% and 30.4%)than in non-elevation group (2.2%,17.8% and 8.9%) (all P < 0.01). Conclusion ST segment elevation in lead aVR may be a predictor of left main coronary artery and proximal left anterior descending coronary artery lesion or multi-vessel le-sion.
