Abstract:
Objective To investigate the clinical value of cardiac troponin Ⅰ(cTnⅠ) and creatinine kinase MB(CK-MB) in early diagnosis of myocardial injury(MCI) in neonatal asphyxia.Methods The serum cTnⅠ and CK-MB in neonates [34 with asphyxia and MCI,38 with asphyxia but no MCI(NMCI)],and 30 cases of normal control(NC) were measured with direct immunoassay chemiluminometric technology and immunoinhibition enzymes-activated assay.Results The cTnⅠ level in NC group had no changes within 10 days after birth,MCI group were significantly higher than those in NMCI and NC groups(all P0.05).The diagnostic sensitivity,specificity and accuracy of cTnⅠ for neonates with MCI were 91%,88% and 89%,respectively;and of CK-MB were 85%,68% and 74%,respectively.Conclusions cTnⅠ and CK-MB can be taken as early diagnostic markers of MCI in neonates with asphyxia,(cTnⅠ) is better than CK-MB.
