Abstract:
Objective To investigate the application of plasma creatine kinase isoenzyme (CK-MB) ,N-ter-minal pro-brain natriuretic peptide(NT-proBNP)and myocardial nutrient-1(CT-1)in the diagnosis of neonatal asphyxia complicating myocardial injury .Methods Eighty cases of neonatal asphyxia in the hospital from Jan-uary to December 2016 were selected ,including 28 cases in the asphyxia non-myocardial injury group ,32 cases in the mild asphyxia myocardial injury group and 20 cases in the severe asphyxia myocardial injury group .Oth-er 80 healthy neonates were selected as the control group .The levels of plasma CK-MB ,NT-proBNP and CT-1 on 1 ,3 ,5 d after birth were measured by adopting the ELISA method .The relationship between plasma CK-MB ,NT-proBNP and CT-1 levels with prognosis in neonatal asphyxia was analyzed .Then the application value of plasma CK-MB ,NT-proBNP and CT-1 in the prognosis evaluation of neonatal asphyxia complicating myo-cardial injury was analyzed by using the receiver operating characteristic (ROC) curve .Results Plasma NT-proBNP ,CK-MB and CT-1 levels in the control group had no statistically significant difference among 1 ,2 ,3 d after birth (P>0 .05) ,but plasma CK-MB ,NT-proBNP and CT-1 levels on postnatal 3 d in the neonatal as-phyxia group reached the peak value ,plasma CK-MB ,NT-proBNP and CT-1 level on postnatal 1 ,3 d in the se-vere asphyxia myocardial injury group and mild asphyxia myocardial injury group were significantly higher than those in the non-myocardial injury group and control group ,and w hich in the non-myocardial injury group were higher than those in the control group ,the differences were statistically significant (P<0 .05) .Plasma NT-proBNP ,CK-MB and CT-1 levels on postnatal 5 d in the non-myocardial injury group and mild asphyxia myocardial injury group returned to normal levels ,w hile w hich in the severe asphyxia myocardial injury group were still higher than those in the other groups ,the differences were statistically significant (P<0 .05) .The levels of plasma CK-MB ,NT-proBNP and CT-1 in the death neonates with neonatal asphyxia were higher than those in the survival neonates ,and the difference was statistically significant (P<0 .05) .The sensitivity and specificity of combined detection of plasma CK-MB ,NT-proBNP and CT-1 for the prognosis diagnosis in neo-nates with asphyxia complicating myocardial injury were higher than that of single index .Conclusion The early determination of plasma CK-MB ,NT-proBNP and CT-1 levels will be helpful to effectively evaluate the myocardial injury severity and prognosis in asphyxia neonates and has an important clinical value .
