摘　　要：目的:分析联合应用高敏心肌肌钙蛋白T和心电图碎裂QRS波在急性心肌梗死中的诊断价值。方法:选择2021年1月—2023年12月在晋江市医院接受治疗的急性心肌梗死患者,共80例,作为观察组,同期选择相同例数的体检人员,将其纳入对照组。检查两组的高敏心肌肌钙蛋白T、心电图碎裂QRS波,分析两者在急性心肌梗死中的应用价值。另外,根据疾病分型将急性心肌梗死分为ST段抬高型心肌梗死和非ST段抬高型心肌梗死,并分析高敏心肌肌钙蛋白T、心电图碎裂QRS波诊断ST段抬高型心肌梗死的价值。结果:观察组高敏心肌肌钙蛋白T水平高于对照组,差异有统计学意义(t=14.302,P=0.000)。观察组心电图碎裂QRS波发生率高于对照组,差异有统计学意义(χ^(2)=62.976,P=0.000)。ST段抬高型心肌梗死患者的高敏心肌肌钙蛋白T水平及心电图碎裂QRS波发生率均高于非ST段抬高型心肌梗死患者(P<0.05)。高敏心肌肌钙蛋白T、心电图碎裂QRS波及两者联合诊断急性心肌梗死的AUC分别为0.984、0.788、0.988,诊断ST段抬高型心肌梗死的AUC分别为0.838、0.707、0.865。结论:采用高敏心肌肌钙蛋白T与心电图碎裂QRS波相结合的方式诊断急性心肌梗死,能够有效提升诊断的准确度,且在一定程度上可以对急性心肌梗死类型进行鉴别。Objective:To analyze the diagnostic value of high sensitivity cardiac troponin T combined with electrocardiogram fragmentation QRS wave in acute myocardial infarction.Method:A total of 80 patients with acute myocardial infarction who received treatment in Jinjiang City Hospital from January 2021 to December 2023 were selected as the observation group,and the same number of medical examiners were selected during the same period to be included in the control group.The high sensitivity cardiac troponin T and electrocardiogram fragmentation QRS wave were examined in the two groups,and the application value of both in acute myocardial infarction were analyzed.In addition,acute myocardial infarction was divided into ST segment elevation myocardial infarction and non-ST segment elevation myocardial infarction according to the disease type,and the diagnostic value of high sensitivity cardiac troponin T and electrocardiogram fragmentation QRS wave in ST segment elevation myocardial infarction were analyzed.Result:The level of high sensitivity cardiac troponin T in the observation group was higher than that in the control group,the difference was statistically significant(t=14.302,P=0.000).The incidence of electrocardiogram fragmentation QRS wave in the observation group was higher than that in the control group,the difference was statistically significant(χ^(2)=62.976,P=0.000).The level of high sensitivity cardiac troponin T and the incidence of electrocardiogram fragmentation QRS wave in patients with ST segment elevation myocardial infarction were higher than those in patients with non-ST segment elevation myocardial infarction(P<0.05).The AUC of high sensitivity cardiac troponin T,electrocardiogram fragmentation QRS wave and their combination in the diagnosis of acute myocardial infarction were 0.984,0.788,0.988,respectively,and in the diagnosis of ST segment elevation myocardial infarction were 0.838,0.707,0.865,respectively.Conclusion:The combination of high sensitivity cardiac troponin T and electrocardiogram fragm
