STaVR抬高对急性冠状动脉综合征预后评估的价值

Prognostic Value of ST Segment Elevation in Lead aVR in Patients with Acute Coronary Syndrome

目的探讨心电图STaVR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STaVR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STaVR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 coronary 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 lesion.
