Introduction[edit | edit source]

Preeclampsia is a life-threatening cardiovascular disorder associated with pregnancy. Preeclampsia is marked by hypertension and proteinuria at 20 weeks of gestation. The underlying cause is not precisely known but likely heterogenous. Ample research suggests that for some women with preeclampsia, both maternal and placental vascular dysfunction plays a part in its' evolution and can carry on into the postpartum period. Possible changes include impaired placentation, and endothelial damage.[1]

Maternal Consquences[edit | edit source]

Preeclampsia is associated with an increased relative risk for the development of end-stage kidney disease (ESKD) in the mother.

Research shows that women with a history of preeclampsia are 60% more likely to experience ischemic stroke and also have an increased risk of hemorrhagic stroke and venous thromboembolism[2].

Women with a history of preeclampsia have increased white matter hyperintensities on brain magnetic resonance imaging9,106, a marker of cerebral small vessel disease that is highly associated with stroke and dementia [3]

Neonatal Consequences[edit | edit source]

The neonatal outcomes of preeclampsia identified are; preterm birth, stillbirth, low birth weight (LBW), low Apgar score, intrauterine growth reduction (IUGR), neonatal intensive care unit (NICU) admission.[4]

Other differences include delayed physical development and sensorimotor reflex maturation, increased body mass index, changes in neuroanatomy and reductions in cognitive function, and hormonal changes.[2]

Preeclampsia is one of three conditions that constitute the syndrome of ischaemic placental disease, a group of pathologies that also includes placental abruption and intrauterine growth restriction.[5]
