摘　　要：目的 探讨心电图aVR导联T波形态在急性前壁心肌梗死患者的病情评估及近期预后中的价值。方法 回顾性分析322例进行急诊经皮冠状动脉介入术(PCI)的急性前壁ST段抬高型心肌梗死患者的相关资料,根据aVR导联T波形态分为T波直立组和T波非直立组,通过比较组间相关指标的差异来评估2组患者的病情及判断预后。结果 T波直立组较T波非直立组:年龄更大,血白细胞、超敏CRP更高,心功能更差,多部位心肌梗死比例更高,冠脉病变程度更重,住院天数更长及院内不良事件发生率更高,上述指标组间比较差异均具有统计学意义(P<0.05)。aVR导联T波直立是院内不良心血管事件的独立危险因素。结论 急性前壁心肌梗死患者入院后即刻床旁心电图中aVR导联T波直立者病情更重、预后更差。Objective To explore the value of T-wave shape in aVR lead of electrocardiogram in evaluating the condition and short-term prognosis of patients with acute anterior wall myocardial infarction.Methods The related indexes of 322 patients with acute anterior wall ST-segment elevation myocardial infarction who underwent emergency PCI were retrospectively analyzed.According to the T wave shape of aVR lead, the patients were divided into T-wave upright group and T-wave non-upright grou.The condition of the two groups was evaluated and the prognosis was judged by comparing the differences of the relevant indexes between the two groups.Results Compared with T-wave non upright group, the T-wave upright group was older, with higher white blood cells and high-sensitivity CRP,worse cardiac function, higher proportion of multiple site myocardial infarction, more severe coronary artery disease, longer hospitalization days and higher incidence of adverse events in hospital.The differences of above indexes between these groups were statistically significant(P<0.05).T-wave upright in lead aVR was an independent risk factor for adverse cardiovascular events in hospital.Conclusion The patients with acute anterior wall myocardial infarction have more seriously condition and worse prognosis in the group of T-wave upright with aVR lead of bedside ECG at the moment of admission.
