Vertical T wave in aVR lead of electrocardiogram in prediction of prognosis of NSTEMI patients with interventional therapy

摘要:

目的分析心电图aVR导联的直立T波对非ST段抬高型心肌梗死(NSTEMI)患者介入治疗预后的预测价值。方法前瞻性选择2018年8月至2020年8月确山县人民医院收治的105例NSTEMI患者作为研究对象,所有患者均接受介入治疗,评估患者预后情况。所有患者接受心电图检查,分析心电图aVR导联直立T波对NSTEMI患者介入治疗预后的预测价值。结果随访至治疗后6个月,105例患者中预后不良32例(30.48%),预后良好73例(69.52%);预后不良组ST段压低程度、导联数高于预后良好组,aVR导联直立T波占比高于预后良好组(P<0.05);绘制受试者工作特征(ROC)曲线得到,ST段压低程度、导联数、aVR导联直立T波预测NSTEMI患者介入治疗预后的曲线下面积(AUC)>0.7,其中aVR导联直立T波的预测价值高。结论心电图ST段压低程度、导联数及aVR导联直立T波对NSTEMI介入治疗患者预后具有较高的预测价值。

Abstract:

【Objective】 To analyze the predictive value of the vertical T wave in aVR lead of electrocardiogram in the prognosis of patients with non-ST-segment elevation myocardial infarction(NSTEMI) after interventional therapy. 【Methods】 A total of 105 NSTEMI patients treated in our hospital from August 2018 to August 2020 were prospectively selected as the study subjects, all patients were treated with interventional therapy, the prognosis of patients was evaluated. All patients were examined by electrocardiogram, the predictive value of the vertical T wave in aVR lead of electrocardiogram in the prognosis of NSTEMI patients after interventional therapy was analyzed. 【Results】 Followed up to 6 months after treatment, among 105 patients, 32 had poor prognosis, accounting for 30.48% and 73 had good prognosis, accounting for 69.52%;the ST-segment depression and lead number of poor prognosis group were higher than those in the good prognosis group, and the proportion of vertical T wave in a VR lead was higher than that of the good prognosis group(P<0.05);the ROC curve was drawn and showed that the AUC of ST-segment depression, the number of leads and the vertical T wave of aVR lead in predicting the prognosis of NSTEMI patients after interventional therapy were >0.7, of which the prediction value of aVR leads vertical T wave was high. 【Conclusion】 ST-segment depression, lead number and vertical T wave in aVR lead have higher predictive value in prognosis of NSTEMI patients after interventional therapy.
