Abstract
Preeclampsia is defined as persistent hypertension (≥140 systolic and/or ≥90 diastolic) after 20 weeks of gestation in the presence of proteinuria (>300 mg in 24 hours) and occurs in 3% to 5% of all pregnancies (predominantly in nulliparous women). Severe preeclampsia requires the diagnosis of an organ dysfunction (e.g., CNS involvement, oliguria, pulmonary edema), proteinuria of ≥ 5 g in 24 hours or blood pressure of ≥160 systolic or ≥110 diastolic on two occasions at least six hours apart. It needs to be distinguished from chronic hypertension (present before and during pregnancy) and gestational hypertension (occurs after 20 weeks of gestation without organ system involvement).
