The newer terminology reflects simply relation of pregnancy with either the onset or first detection of hypertension; the question of causation, while pathogenetically interesting, is not the important point for most health care purposes. This classification treats HELLP syndrome as a type of preeclampsia rather than a parallel entity. Chronic hypertension
Chronic hypertension is a type of high blood pressure in a pregnant woman that is pre-existing before conception, diagnosed early in pregnancy, or persists significantly after the end of pregnancy. It affects about 5% of all pregnancies and can be a primary disorder of essential hypertension or secondary to another condition; it is not caused by pregnancy itself.The diagnostic criteria for chronic hypertension are typically considered to be at least two separate blood pressure readings taken at least four hours apart with systolic blood pressure ≥ 140mmHg, diastolic blood pressure ≥90 mmHg, or both, identified before pregnancy, before 20 weeks gestation, or persisting at least 12 weeks after giving birth. However, there is some controversy over the utility of adopting lower thresholds for diagnosis of chronic hypertension, which is more consistent with recent recommendations from the American College of Cardiology and the American Heart Association for the diagnosis of hypertension in adults.
