1.Chronic Hypertension: hypertension diagnosed before pregnancy, before 20 weeks' gestation, or elevated BP that is first diagnosed during pregnancy and persists after 42 days postpartum
2.Pre-eclampsia:onsetofelevatedBPandproteinuriaafter20weeks'gestation in a patient known previouslyto be normotensive.Exceptions are in the casesof trophoblastic disease or multiple gestation,when pre-eclampsia may appearbefore 20weeks'gestation
2.Pre-eclampsia: onset of elevated BP and proteinuria after 20 weeks' gestation in a patient known previously to be normotensive. Exceptions are in the cases of trophoblastic disease or multiple gestation, when pre-eclampsia may appear before 20 weeks' gestation
