Abstract
目的评估血清心肌肌钙蛋白I(cTnI)对小儿心肌炎的诊断价值,并与肌酸激酶同功酶MB(CK-MB)进行对比研究.方法全自动生化分析仪对cTnI及CK-MB进行定量检测.结果①心肌炎组cTnI及CK-MB均明显高于正常对照组(P<0.001).cTnI升高22例,占73%,CK-MB升高15例,占50%,cTnI与CK-MB呈正相关.②治疗2周后cTnI与对照组比较有显著性差异(P<0.001),CK-MB与对照组无显著性差异(P>0.05).③心肌炎组13例ST-T改变患儿测cTnI升高12例(92%),CK-MB升高6例(46%).结论 cTnI及CK-MB对小儿肌炎的诊断均较敏感.cTnI诊断时间窗宽于CK-MB,特异性高于CK-MB.
