#456 - [Journal Club] - 🫀 From The Heart - Why Does a Sicker Mom Sometimes Mean a Stronger Neonatal Heart?

In this small prospective pilot study, Adrianne and Nim explore a domain rarely discussed on rounds, how a mother's cardiovascular function in preeclampsia shapes her newborn's circulatory transition. Using maternal echo and neonatal electrical cardiometry across 13 mother-baby dyads, the authors found an inverse relationship: the worse the mother's cardiac function, the higher the neonate's cardiac output, though vascular tone barely budged. It's a compelling hypothesis about placental strain and fetal adaptation. But Nim pushes back hard on the methodology, pairing this paper with a companion study showing electrical cardiometry consistently overestimates cardiac output in neonates, and questioning why daily echoes were performed on these babies but the results never reported.----Linking maternal and neonatal circulation in preeclampsia.
