摘要
目的 探讨体表心电图avL导联T波改变与急性冠状动脉综合征(ACS)患者预后的关系.方法 选择2021年2月-2022年9月于宜春市中医院就诊的ACS患者100例为研究对象,将患者按照有无不良心血管终点事件发生分为预后不良组(24例)、预后良好组(76例),均行心电图检查,比较两组心肌损伤、心电图特征,并分析影响不良心血管终点事件的危险因素.结果 两组心肌损伤各项指标对比,无统计学差异(P＞0.05);预后不良组ST段压低发生率为62.50％、avL导联T波改变发生率为87.50％、ST段升高发生率为66.67％、病理性Q波发生率为75.00％,均高于预后良好组(P＜0.05);病理性 Q 波(β=2.343,OR=10.412,95％CI=3.572-30.352)、avL 导联 T波改变(β=1.681,OR=5.372,95％CI=1.476-19.554)、ST 段压低(β=1.999,OR=7.381,95％CI=2.689-20.257)、ST 段升高(β=2.096,OR=8.133,95％CI=2.934-22.544)均是 ACS 患者出现不良心血管终点事件的危险因素(P＜0.05).结论 体表心电图avL导联T波改变是影响ACS患者预后的危险因素.
Abstract
Objective To investigate the relationship between changes of avL lead T-wave and prognosis in patients with acute coronary syndrome(ACS).Methods 100 patients with ACS who were treated in Yichun Hospital of Traditional Chinese Medicine from February 2021 to Sep-tember 2022 were selected as the study objects,and the patients were divided into a poor progno-sis group(24 cases)and a good prognosis group(76 cases)according to the occurrence of adverse cardiovascular endpoint events.Ecg examination was performed in both groups,and myocardial injury and ECG characteristics were compared between the two groups.Risk factors for adverse cardiovascular endpoint events were analyzed.Results There was no significant difference in the indexes of myocardial injury between the two groups(P＞0.05).The incidence of ST segment depression(62.50％),T-wave change(87.50％),ST segment elevation(66.67％)and patho-logical Q wave(75.00％)in the poor prognosis group were higher than those in the good progno-sis group(P＜0.05).Pathological Q wave(β=2.343,OR=10.412,95％CI=3.572-30.352),avL lead T wave change(β=1.681,OR=5.372,95％CI=1.476-19.554),ST segment depres-sion(β=1.999,OR=7.381,95％CI=2.689-20.257)and elevated ST segment(β=2.096,OR=8.133,95％CI=2.934-22.544)were risk factors for adverse cardiovascular endpoint events in ACS patients(P＜0.05).Conclusion The change of avL lead T wave in body surface electrocar-diogram is a risk factor for the prognosis of ACS patients.
