小儿急性病毒性心肌炎几项实验室诊断指标的分析

目的：对急性病毒性心肌炎（VMC）临床常用实验室指标的诊断价值分析，方法：58例急性VMC，均检测血清肌钙蛋白I（cTnI)，心肌酶谱及病毒抗体，回顾性分析上述指标的临床诊断价值。结果：58例VMC，cTnI阳性率67．24％（39／58），病毒感染阳性率60．34％（35／58），其中柯萨奇病毒感染最常见，占41．38％，CK－MB阳性率48．28％，cTnI的诊断价值较CK－MB有显著性差异（P＜0．05），结论：急性VMC时，血清cTnI较CK－MB阳性率高，其病原学以柯萨奇病毒最常见。

Analyses on some laboratory diagnostic indexes of children with acute viral myocarditis

Objective To investigate the values of some common laboratory indexes in the diagnosis of acute viral myocarditis (VMC) in children. Methods Serum cTnI, CK MB and virus antibody were detected in 58 children with acute viral myocarditis, and their results were analyzed for diagnostic value. Results Among 58 cases, the positive rate of cTnI was 67.24% (39/58), of viral infection 60.34% (35/58), and of serum CK MB 48.28% (28/58). Serum cTnI diagnostic value was more significant than CK MB ( P <0.05). Coxsackie virus was found to be the most common virus in children VMC, covering 41.38% (24/35), while, cytomegalovirus and Epstein Barrvirus virus were 12.07% and 10.34%, respectively. Conclusion Serum cTnI is a more significant index than CK MB in the diagnosis of VMC. Coxsackie virus is the most common pathogen in children.
