摘　　要：目的探讨aVR导联T波方向对急性sT段抬高型心肌梗死患者远期预后的预测价值。方法收集322例急性sT段抬高型心肌梗死患者的临床资料，根据心肌梗死症状发作后行经皮冠脉介入治疗前心电图aVR导联T波方向，分为T波直立组与T波非直立组。比较两组患者出院后2年内主要心脏不良事件发生情况并对影响预后因素进行Cox回归分析。结果T波直立组随访期间主要心脏不良事件发生率高于T波非直立组，组间差异有统计学意义（P〈0．05）；aVR导联T波直立、年龄是急性sT段抬高型心肌梗死后2年内主要心脏不良事件发生的独立危险因素。结论aVR导联T波方向对急性sT段抬高型心肌梗死患者远期预后有较好的预测价值。Objective To explore the prognostic significance of T wave direction in lead aVR in patients with acute ST-segment elevation myocardial infarction （ASTEMI）. Methods A total of 322 pa- tiens with ASTEMI was examined. The patients were classified into 2 groups （T-wave positive, and T-wave non-positive） base on the direction of T wave in lead aVR. This study was ought to determine the association of T wave direction in lead aVR with the incidence rate of major adverse cardiac events （MACE） after discharge 2 years. Results After discharge 2 years, T-wave positivity patients had higher incidence of MACE than T-wave non-positive patients （P 〈0. 05 ）. Multivariate Cox proportional hazards regression analyses showed that age, and upright T wave in lead aVR were significantly associated with the primary end point. Conclusions T wave direction in lead aVR is a powerful prognostic marker for long-term prognosis.
