病毒性心肌炎患儿心肌肌凝蛋白轻链-1的变化及意义

目的探讨心肌肌凝蛋白轻链-1(CMLC-1)在小儿病毒性心肌炎(VMC)诊治中的应用价值。方法对63例VMC患儿(VMC组)和42例健康儿(对照组)检测血清CMLC-1和心肌肌钙蛋白T(cTnT),进行相关性分析;并对不同心功能级别VMC患儿CMLC-1比较,VMC患儿心血管事件发生组与未发生组CMLC-1、左室射血分数(LVEF)比较。结果 VMC组患儿血清CMLC-1、cTnT水平较对照组明显升高(均P<0.01),治疗后较治疗前明显下降(P<0.01)。CMLC-1与cTnT水平呈显著正相关(P<0.01)。心功能分级不同,CMLC-1水平不同,心功能愈差,CMLC-1水平愈高,差异有统计学意义(P<0.01),发生心血管事件的VMC患儿血清CMLC-1水平明显高于未发生者(P<0.01),CMLC-1水平与LVEF呈显著负相关(P<0.01)。结论血清CMLC-1水平可作为VMC诊断、病情严重程度评估及预后判定的指标。

Change of serum cardiac myosin light chain-1 in children with viral myocarditis and its significance

Objective To determine the role of serum cardiac myosin light chain-1(CMLC-1) in the diagnosis and prognosis of children with viral myocarditis.Methods Sixty three patients with VMC were chosen into a positive group and forty two healthy children into a control group,and CMLC-1 and cTnT of both groups were detected.The correlation analysis and comparisons on various heart functions were made.The serum CMLC-1 contents were measured and the left ventricular ejection fraction were detected in complicated with ...
