Systemic vascular reactivity in an aortic coarctation model of preeclampsia in the rat.

Preeclampsia (preECL), a hypertensive disorder of pregnancy, which occurs only in humans, is dangerous for mother and fetus. It may be caused by placental hypoxia triggering the release of a circulating factor that damages the maternal endothelium leading to vasoconstriction and hypertension. Our primary objective was to determine if systemic vascular reactivity is altered in a rat aortic coarctation (ACOR) model of preECL.
