Both circulating and placental levels of soluble fms-like tyrosine kinase-1 (sFlt-1) are higher in women with pre-eclampsia than in women with normal pregnancy. [26] sFlt-1 is an anti-angiogenic protein that antagonizes vascular endothelial growth factor (VEGF) and placental growth factor (PIGF), both of which are proangiogenic factors. [15]
Preeclampsia is a pregnancy complication in which a pregnant woman develops high blood pressure, which can potentially lead to eclampsia. ... of-pregnancy ...
Eclampsia is the onset of seizures (convulsions) in a woman with pre-eclampsia. [1] Pre-eclampsia is a hypertensive disorder of pregnancy that presents with three main features: new onset of high blood pressure , large amounts of protein in the urine or other organ dysfunction, and edema .
Eclampsia is a complication of pre-eclampsia, a condition that affects some pregnant women
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.

This changes them from high-resistance low-flow vessels into large dilated vessels that provide good perfusion, and oxygenation to the developing placenta. When invasion is shallow it is inadequate, the arteries remain narrow at their openings into the intervillous space, and is the cause of pre-eclampsia, fetal growth restriction and still birth.
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]
The genetic roots of gestational hypertension and pre-eclampsia are certain, as women with a family history of the condition are three times more likely to develop it when they are pregnant. [25] One of the potential causes of gestational hypertension and pre-eclampsia is when the trophoblast does not invade far enough into the uterine lining. [26]
