简要总结

The goal of this observational study is to learn about cardiac function and remodelling and metabolomic profiles in fetuses and infants who were exposed to a threatened preterm labor (TPL) during pregnancy.

详细描述

The main questions it aims to answer are:

  • Evaluate the impact of threated preterm labour in cardiovascular and metabolic programming in fetal life and early infancy.
  • Describe prenatal and postnatal patterns of cardiac remodelling associated to threatened preterm labour.
  • Describe fetal growth patterns associated to threatened preterm labour.
  • Describe metabolomic profiles in umbilical cord blood associated to cardiovascular programming in fetuses exposed to threatened preterm labour.

The study's main tasks are:

  • To perform an antenatal echocardiography of the exposed cohort is performed during the admission due to TPL or preterm spontaneous rupture of membranes (SRM).
  • All participants are asked to fill a diet and stress questionnaire.
  • To collect cord blood at the time of delivery.
  • To perform a postnatal echocardiography six months after birth.

Researchers will compare fetuses and infants who were exposed to TPL to those who were not exposed to TPL during pregnancy to see if threre are any differences in cardiac function and remodelling.
