摘要
目的:通过对急性心肌梗死实施高敏肌钙蛋白T联合心电图碎裂QRS波诊断,探讨其临床价值。方法:以我院2020年6月—2021年8月期间收治的74名急性心肌梗死患者以及同期74名例行健康体检者为研究对象,依次设为研究组和对照组,同时根据是否ST段抬高将急性心肌梗死分为ST段抬高型急性心肌梗死(STEMI)和非ST段抬高型急性心肌梗死(NSTEMI)。观察比较两组患者及对照组高敏肌钙蛋白T(hs-TnT)水平及心电图碎裂QRS波发生率;分别比较hs-TnT、心电图碎裂QRS波及hs-TnT联合心电图碎裂QRS波在急性心肌梗死中的诊断效能,并将造影结果作为金标准。结果:研究组患者的血清hs-TnT含量、心电图碎裂QRS波发生率明显均高于对照组(P<0.05);STEMI组血清hs-TnT含量和心电图碎裂QRS波发生率均高于NSTEMI组,差异均有统计学意义(P<0.05);另一方面,hs-TnT的敏感度低于心电图碎裂QRS波检测,特异性高于心电图碎裂QRS波检测,二者阳性、阴性预测值对比无明显差异(P>0.05);此外,hs-TnT、心电图碎裂QRS波的敏感度、特异性、阳性预测值、阴性预测值等诊断效能均低于二者联合的检测方式(P<0.05)。结论:高敏肌钙蛋白T联合心电图碎裂QRS波在急性心肌梗死的早期诊断中效果较好,敏感度、特异性、阳性预测值、阴性预测值较好,对患者的早期病理分析具有重要意义,值得广泛推广应用。
Objective:To explore the early diagnosis value of high-sensitivity troponin T combined with QRS wave of electrocardiogram in the early diagnosis of acute myocardial infarction.Methods:The74 patients with acute myocardial infarction admitted to our hospital from June 2020 to August 2021 and 74 patients undergoing routine physical examination during the same period were selected as the study group and the control group.At the same time,according to whether ST Segmental elevation divides acute myocardial infarction into ST-segment elevation acute myocardial infarction(STEMI)and non-ST-segment elevation acute myocardial infarction(NSTEMI).To observe and compare the highsensitivity troponin T(hs-TnT)levels and the incidence of electrocardiographic fragmented QRS complex between the two groups of patients and the control group;compare hs-TnT,electrocardiographic fragmented QRS complex and hs-TnT combined with electrocardiographic fragmented QRS complex.The diagnostic efficiency of acute myocardial infarction,and the angiography result is regarded as the"gold standard".Results:The serum hs-TnT content and the incidence of ECG fragmentation QRS complex in the study group were significantly higher than those in the control group(P<0.05);the serum hs-TnT content and the incidence of ECG fragmentation QRS complex in the STEMI group were higher than those of NSTEMI Group(P<0.05);on the other hand,the sensitivity of hs-TnT was lower than the QRS detection of ECG fragmentation,and the specificity was higher than that of QRS detection of ECG fragmentation.Both positive and negative predictions There was no significant difference in the comparison of values(P>0.05);in addition,the sensitivity,specificity,positive predictive value,and negative predictive value of hs-TnT and ECG fragmented QRS complex were lower than the combined detection method(P<0.05).Conclusion:The combination of high-sensitivity troponin T combined with electrocardiographic fragmentation QRS has a good effect in the early diagnosis of acute myocardial infarction,with good sensitivity,specificity,positive predictive value,and negative predictive value,which is of great significance for the early pathological analysis of patients,It is worthy of widespread promotion and application.
