Abstract: Introduction: In the last few years the use of cardiac troponin I and T, as diagnostic and prognostic factors of ischemic myocardial injury both in adult and neonatal medicine has been of great interest. Objective: The objective of our research was to investigate the significance of cardiac troponin I (cTnI) as an early indicator of the presence and severity of hypoxic-ischemic encephalopathy (HIE) in newborns. Methods: We analyzed 55 term newborns with HIE diagnosed based on clinical findings and ultrasonographic examination of the central nervous system. Serum concentration of cTnlultra was determined by immunoenzyme method during the first 24-48 hours after birth, and the obtained findings were compared with the values of identical parameter in 36 healthy term newborns. Results: During the first 24-48 hrs after birth, serum concentration of cTnl-ultra was significantly higher (p<0.0005) in term newborns with HIE (0.135±0.207 ug/l) and median (0.07,0.01-006 μg/1) in comparison to control group (0.0183±0.026 ug/l and median 0.01 (0.01-0.01 μg/l), with the cTnl-ultra level rising proportionally to the clinical HIE stages. The increase of cTnl-ultra of <0.12 μg/l indicated the development of significant cerebral damage with the sensitivity of 75% and specificity of 72.2%, while the cTnl-ultra level of <0.13 μg/l was a significant mortality predictor with sensitivity of 76.9% and specificity of 73.8%. Conclusion: The second generation cardiac troponin I assay highly correlates with clinical and ultrasonographic findings in neonates with HIE, so that it can be used as a significant diagnostic and prognostic indicator of this pathological condition.
