ABSTRACT
Objective To investigate the changes and clinical significance of plasma N‐terminal pro‐brain natriuretic peptide (Nt‐proBNP) in patients with asphyxia of newborns combined with myocardial injury .Methods Fifty‐eight term neonates with neonatal asphyxia born within 24 h were included in our study ,18 of the 25 severe asphyxia cases were combined with myocardial injury ,15 of 33 mild asphyxia cases were with myocardial injury ,there were 25 subjects were not cardiac injured after asphyxia to‐tally .Patients of the same age without asphyxia or any cardiovascular disease were recruited into the control group .Levels of plasma Nt‐proBNP and creatine kinase isoenzyme (CK‐MB) were detected on the first ,third and the fifth days after birth for statistical a‐nalysis .Results On the first and third days after birth ,levels of plasma Nt‐proBNP in severe and mild asphyxia combined with my‐ocardial injury group were significantly higher than the groups without myocardial injury and the control (P0 .05) .On the first day after birth ,levels of Nt‐proBNP ,CK‐MB were positively corre‐lated in the mild asphyxia group (r=0 .58 ,P<0 .05) and severe asphyxia group (r=0 .47 ,P<0 .05) .On the first day after birth , the cutoff value for myocardial injury was 695 .87 fmol/mL ,the area under the ROC curve was 0 .763 ,with the sensitivity of 71 .9%and specificity of 65 .4% ,the positive predictive value was 73 .3% and negative predictive value was 63 .8% .Conclusion The Nt‐proBNP level has important clinical value for early evaluation of the severity of myocardial injury after asphyxia .
