Hypertension in pregnancy is defined by a systolic blood pressure > or = 140 mm Hg and a diastolic blood pressure of > or = 90 mm Hg or by a rise in blood pressure of systolic > or = 30 mm Hg and diastolic > or = 15 mm Hg. High blood pressures are found in 5-10% of all pregnancies. The outcome of pregnancy is influenced by the fact whether there occurs a proteinuria in addition to hypertension. ⋯ The prophylactic use of low-dose heparin, which has lead to a significant decreased incidence of preeclampsia in retrospective analysis, is now the object of a randomized, controlled trial in our hospital. All women who suffered from a preeclampsia should have a check-up after 3-6 months. Preexisting pathologies are found in up to 40% of patients, mostly in multiparae, i.e. chronic hypertension, nephropathy, endocrine pathologies, anomalies of blood coagulation and antiphospolipid-syndrome.
