Hypertensive disorders during pregnancy: clinical applicability of risk prediction models.

摘要

Hypertension complicates approximately 6-11% of all pregnancies [1-3]. According to current guidelines, hypertensive disorders during pregnancy may be classified into four categories: chronic hypertension; preeclampsia-eclampsia; preeclampsia superimposed on chronic hypertension; and gestational hypertension (preferred over the older term of pregnancy-induced hypertension) [4]. Hypertensive disorders during pregnancy are important causes of perinatal and maternal morbidity and mortality, particularly when elevated blood pressure (BP) is due to preeclampsia, either alone or superimposed on chronic vascular disease [1-3]. They rank among the leading causes of maternal mortality, along with embolism, hemorrhage and nonobstertic injuries, accounting for almost 15% of such deaths [2].
