摘　　要：目的分析心电图预测冠状动脉左回旋支急性闭塞严重程度及预后的临床价值。方法选择2022年1月至2023年12月南阳市中心医院收入的96例冠状动脉左回旋支急性闭塞患者进行回顾性分析,根据不同心电图改变分为ST-D组、ST-E组、N-ST组,各32例,就三组患者临床资料[性别、年龄、病史、肌钙蛋白Ⅰ(TnⅠ)、肌酸激酶(CK)]、冠状造影结果、心肌梗死面积和不良心血管事件发生情况进行组间比较。结果三组患者性别、年龄及病史相关资料相比,差异无统计学意义(P>0.05);ST-E组患者TnⅠ、CK指标均高于ST-D组、N-ST组,其中以N-ST组指标最低,差异均有统计学意义(P<0.05)。N-ST组患者近端回旋支、远端回旋支低于ST-E组与ST-D组,且ST-D组远端回旋支低于ST-E组;N-ST组钝缘支、侧支循环均高于ST-E组与ST-D组,差异均有统计学意义(P<0.05),而ST-E组、ST-D组患者近端回旋支、钝缘支及侧支循环相比,差异无统计学意义(P>0.05)。心肌梗死面积和不良心血管事件发生情况:N-ST组患者心肌梗死面积低于ST-D组与ST-E组,差异均有统计学意义(P<0.05);三组患者不良心血管事件发生风险相比,差异无统计学意义(P>0.05)。结论通过分析心电图特征,医务人员能够更准确地判断患者的病情严重程度,预测潜在的并发症风险,为临床治疗提供针对性指导。Objective To analyze the clinical value of electrocardiogram(ECG)in predicting the severity and prognosis of acute occlusion of the left circumflex coronary artery.Methods A retrospective analysis was conducted on 96 patients with acute occlusion of the left circumflex coronary artery admitted to Nanyang Central Hospital from January 2022 to December 2023.Based on different ECG changes,patients were divided into three groups:ST-D group,ST-E group,and N-ST group,with 32 cases in each group.Clinical data(gender,age,medical history,troponin I(Tn I),creatine kinase(CK)),coronary angiography results,myocardial infarction area,and the occurrence of adverse cardiovascular events were compared among the groups.Results No significant differences were found in gender,age,or medical history among the three groups(P>0.05).The levels of Tn I and CK in the ST-E group were higher than those in the ST-D and N-ST groups,with the N-ST group having the lowest levels,and the differences were statistically significant(P<0.05).The proximal and distal circumflex branches in the N-ST group were lower than those in the ST-E and ST-D groups,and the distal circumflex branch in the ST-D group was lower than that in the ST-E group.The obtuse marginal branch and collateral circulation in the N-ST group were higher than those in the ST-E and ST-D groups,with significant differences(P<0.05).However,there were no significant differences in the proximal circumflex branch,obtuse marginal branch,and collateral circulation between the ST-E and ST-D groups(P>0.05).Regarding the area of myocardial infarction and the occurrence of adverse cardiovascular events,the N-ST group had a smaller myocardial infarction area compared to the ST-D and ST-E groups,with significant differences(P<0.05).No significant differences were found in the risk of adverse cardiovascular events among the three groups(P>0.05).Conclusion By analyzing the characteristics of the ECG,healthcare professionals can more accurately assess the severity of the patient’s condition and pr
