Maternal peripheral vascular resistance at mid gestation in chronic hypertension as a predictor of fetal growth restriction

We aimed at analyzing the relationship between maternal hemodynamics as expressed by Peripheral Vascular Resistance (PVR) at mid gestation and fetal growth at delivery in chronic hypertension. 152 chronic hypertensive patients were submitted to echocardiography noting PVR at 22-24 weeks' gestation and were followed until delivery noting birthweight centile and the diagnosis of fetal growth restriction (FGR). The logarithmic correlation analysis showed that PVR at mid gestation was strongly related to birthweight at delivery (
