Background: In spite of its potential clinical prognostic significance, only a small number of studies have been conducted to date involving neonatal cardiac troponin-I as an early indicator of significance respiratory dysfunction.

Objective: Aim of this study was to evaluate the clinical significance cardiac troponin-I as marker of cardiorespiratory failure in term newborns. Methods: Cardiac troponin-I level was determined in serum (at 24-48 hours after birth) in 55 term neonates with respiratory distress and 36 healthy, term newborns. The cardiac troponin-I level is correlated with the total duration of oxygen and ventilatory therapy (expressed in days) in both groups with (13/55) or without (32/55) deaths.

Results: Newborns with respiratory distress had a significantly higher level of cardiac troponin-I, compared to the control group, with the largest increase in cardiac troponin-I observed in mechanically ventilated patients (31/55). The length of applied respiratory support was positively correlated with the level of cardiac troponin-I in survivors of respondents, while in the group of children who died the level of cardiac troponin-I was negatively correlated with total duration of respiratory support, and the number of days to death.

Conclusions: The increase in cardiac troponin-I could indicate the development of severe respiratory failure in term neonates with respiratory distress.
