Key result
Intrauterine growth restriction did not alter perinatal cardiac Troponin-I levels compared to normal pregnancies, though strong maternal-fetal correlations were observed (r ≥ 0.498, P ≤ 0.025).
Why the study?
Are perinatal cardiac Troponin-I levels different between intrauterine growth-restricted and normal pregnancies?
Observational (n=80)
Are perinatal cardiac Troponin-I levels different between intrauterine growth-restricted and normal pregnancies?
Cardiac Troponin-I levels do not differ between IUGR and normal pregnancies, suggesting preserved normal heart function in IUGR due to fetal heart sparing and potential placental crossing of cTnI.

cTnI levels appear comparable in IUGR and normal pregnancies; hypothesis-generating for maternal-fetal correlations and requires prospective validation before clinical use.
Intrauterine growth restriction (IUGR) implies fetal hypoxia, resulting in blood flow redistribution and sparing of vital organs (brain, heart). Serum cardiac Troponin-I (cTnI), a well-established marker of myocardial ischaemia, was measured in 40 mothers prior to delivery, the doubly clamped umbilical cords (representing fetal state), and their 20 IUGR and 20 appropriate-for-gestational-age (AGA) neonates on day 1 and 4 postpartum. At all time points, no differences in cTnI levels were observed between the AGA and IUGR groups. Strong positive correlations were documented between maternal and fetal/neonatal values (r > or = .498, P < or = .025 in all cases in the AGA and r > or = .615, P < or = .009 in all cases in the IUGR group). These results may indicate (a) normal heart function, due to heart sparing, in the IUGR group (b) potential crossing of the placental barrier by cTnI in both groups.

Iacovidou et al. (2007) conducted an observational in Intrauterine growth restriction (n=80). Intrauterine growth restriction (IUGR) vs. Appropriate-for-gestational-age (AGA) pregnancies was evaluated on Serum cardiac Troponin-I (cTnI) levels. Intrauterine growth restriction did not alter perinatal cardiac Troponin-I levels compared to normal pregnancies, though strong maternal-fetal correlations were observed (r ≥ 0.498, P ≤ 0.025).
