ARTICLE HIGHLIGHTS
Research background

The myocardial ischemic injury in asphyxiated neonates complicates management and may lead to higher mortality. Cardiac troponin T (cTnT) levels are expected to rise early in myocardial ischemia and remain high for about two weeks.

Research motivation

cTnT levels are better markers than Serum creatinine kinase muscle-brain isoenzyme levels and could be predictive of mortality.

Research objectives

The present study determined cTnT levels in asphyxiated neonates and found out its relationship with echocardiography findings, inotrope requirement, hypoxic-ischemic encephalopathy (HIE) stages, and mortality.

Research methods

cTnT levels are estimated in all asphyxiated neonates along with echocardiography evaluation.

Research results

Among asphyxiated neonates, cTnT levels were elevated in 71.9%. Further, the cTnT levels correlated with increasing grades of ischemic changes in echocardiography. Elevated cTnT levels in 58% of neonates with normal echocardiography findings suggested its role as a biomarker. cTnT levels in neonates with HIE stage III were significantly higher than those with HIE stage I and II. cTnT levels were higher in non-survivors than survivors.

Research conclusions

cTnT could be a potential and clinically useful biomarker for asphyxia related myocardial injury in neonates.

Research perspectives

Further studies to determine the exact cut of levels of cTnT predicting mortality are needed.
