Pre-eclampsia affects 2–8% of pregnancies worldwide. [4] [17] [12] Hypertensive disorders of pregnancy (which include pre-eclampsia) are one of the most common causes of death due to pregnancy. [6] They resulted in 46,900 deaths in 2015. [7] Pre-eclampsia usually occurs after 32 weeks; however, if it occurs earlier it is associated with worse ...
The pathogenesis of pre-eclampsia is poorly understood and may be attributed to factors related to the woman and placenta since pre-eclampsia is seen in molar pregnancies absent of a fetus or fetal tissue. [46] The placenta normally produces the potent vasodilator adrenomedullin but it is reduced in pre-eclampsia and eclampsia. [47]
Preeclampsia superimposed on chronic hypertension occurs when a pregnant woman with chronic hypertension develops signs of pre-eclampsia, typically defined as new onset of proteinuria ≥30 mg/dL (1+ in the dipstick) in at least 2 random urine specimens that were collected ≥4 h apart (but within a 7-day interval) or 0.3 g in a 24-h period. [19]
"Preeclampsia not only affects maternal health but can also significantly impact fetal and neonatal short- and long-term outcomes, such as fetal growth restriction, stillbirth, and other medical ...
This changes them from high-resistance low-flow vessels into large dilated vessels that provide good perfusion, and oxygenation to the developing placenta.

Severe pre-eclampsia involves a BP over 160/110 (with additional signs). It affects 5–8% of pregnancies. [20] Eclampsia – seizures in a pre-eclamptic patient, affect around 1.4% of pregnancies. [21] Gestational hypertension can develop after 20 weeks but has no other symptoms, and later rights itself, but it can develop into pre-eclampsia. [22]
