目的比较心肌肌钙蛋白T(cTnT)与肌钙蛋白I(cTnI)在小儿病毒性心肌炎(VMC)中检测价值。方法对54例急性VMC患儿入院24h内,以及入院后1、2、3周及3个月cTnT和cTnI进行动态观察。结果急性VMC患儿cTnT阳性率显著高于同期cTnI阳性率(P<0.05)。结论cTnT在小儿病毒性心肌炎心肌中检测价值高于cTnI。
Objective To compare the detection of cardiac troponin T (cTnT) and troponin I (cTnI) in children with viral myocarditis (VMC). Methods The dynamic changes of cTnT and cTnI in 54 children with acute VMC within 24h after admission, 1,2,3 and 3 months after admission were observed. Results The positive rate of cTnT in children with acute VMC was significantly higher than that of cTnI in the same period (P <0.05). Conclusion The detection of cTnT in myocardium of children with viral myocarditis is higher than that of cTnI.
