摘　　要：目的探讨平面QRS-T夹角评估急性ST抬高型心肌梗死(STEAMI)患者的临床价值。方法选取2022年1月至2023年10月期间住院治疗的80例急性ST抬高型心肌梗死患者为研究对象。所有患者均执行常规12导联心电图检查,测量平面QRS-T夹角,分为观察组(平面QRS-T夹角>90°)和对照组(平面QRS-T夹角≤90°)。对比两组左心室射血分数(LVEF)、血清肌钙蛋白T(cTnT)、N末端B型利钠肽原(NT-pro BNP)浓度,以及恶性心律失常发生率。结果观察组患者的LVEF低于对照组,cTnT、NT-pro BNP浓度和恶性心律失常发生率高于对照组(P<0.05)。结论当平面QRS-T夹角大于90°时,患者可能面临更大面积的心肌梗死,心功能下降明显,以及恶性心律失常发生几率增高。因此,对于这些患者,应该积极采取血管开通和综合医护措施以改善预后。Objective To explore the clinical value of planar QRS-T angle assessment in patients with acute ST elevation myocardial infarction(STEAMI).Methods Eighty patients with acute ST elevation myocardial infarction who were hospitalized between January 2022 and October 2023 were selected as the study subjects.All patients underwent routine 12 lead electrocardiogram examination and measured the plane QRS-T angle.They were divided into an observation group(plane QRS-T angle>90°)and a control group(plane QRS-T angle≤90°).Compare left ventricular ejection fraction(LVEF),serum troponin T(cTnT),N-terminal B-type natriuretic peptide(NT proBNP)concentration,and incidence of malignant arrhythmia between two groups.Results The LVEF of the observation group patients was lower than that of the control group,and the concentrations of cTnT,NT proBNP,and the incidence of malignant arrhythmia were higher than those of the control group(P<0.05).Conclusions When the plane QRS-T angle is greater than 90°,patients may face a larger area of myocardial infarction,significant decline in cardiac function,and an increased risk of malignant arrhythmia.Therefore,for these patients,active measures such as vascular patency and comprehensive medical care should be taken to improve prognosis.
