目的:探讨超敏肌钙蛋白T和N-末端B型利钠肽原在病毒性心肌炎中的表达及临床意义.方法:选取我院2016年1月～2020年1月患有病毒性心肌炎的患者45例为观察组,同期选择35例体检健康者为对照组;分别抽取两组外周静脉血,比较两组超敏肌钙蛋白T、N-末端B型利钠肽原结果并分析其临床意义.结果:观察组超敏肌钙蛋白T和N-末端B型利钠肽原水平均高于对照组,且血清超敏肌钙蛋白T和N-末端B型利钠肽原水平呈正相关;与单个指标检测相比,血清超敏肌钙蛋白T和N-末端B型利钠肽原联合检测诊断效率较高,其敏感度为97.8％“,”Objective: To investigate the expression and clinical significance of hypersensitive troponin T and N - terminal b - type natreuretic peptide in viral myocarditis. Methods: 45patients with viral myocarditis in our hospital from January 2016 to January 2020 were select-ed as the observation group, and 35 healthy patients were selected as the control group.Peripheral venous blood was extracted from the two groups, and the results of hypersensitive troponin T and N - terminal B - type natrentopeptide were compared between the two groups , and their clinical significance was analyzed. Results: The hypersensitive troponin T and N - terminal B - type naturetic peptide raw water in observation group were higher than those in control group on average, and the serum hypersensitive troponinT and n-terminal B-type naturetic peptide levels were posi-tively correlated. Compared with single index , the combined detection of serum hypersensitive troponin T and N - terminal B - type natreuretic peptide had a higher diagnostic efficiency , with a sensitivity of 97. 8％ , specificity of 94. 3％ and ACUpoint 0. 962. Conclusion: Viral myocarditis can lead to the increase of serum hypersensitive troponin T and N-terminal b-type natrentipropeptide levels, and the sensitivity and specificity of the combined detection of the two are high, which can be used as a reference for the early diagnosis of viral myocarditis.
