Elevated cardiac troponin T concentrations in preterm infants with respiratory distress syndrome suggest the presence of myocardial damage.

Elevated cTnT in preterm RDS may indicate myocardial injury; hypothesis-generating and should not yet change practice.
In preterm infants with respiratory distress syndrome (RDS), cardiac function is negatively influenced by the severity of the lung disease. On day 2 of life, cardiac troponin T (cTnT), biochemical marker of myocardial injury, was measured in 46 preterm infants (gestational age ≤32 wk), 26 with RDS and 20 without: median (range) 0.38 (0.02–1.57) μgL vs 0.13 (0.02–0.85) μgL, respectively. Conclusion: High cTnT concentrations in preterm infants with RDS suggest the presence of myocardial damage in this group of high‐risk patients.
