Abstract
Introduction: Hypertension disorders are the most commonly diagnosed pregnancy complications and involve 5 to 10% of all pregnancies (1). These disorders account for, roughly, 16% of maternal mortality in developed countries. Hypertension disorders are categorized as chronic hypertension and a group of pregnancy-specific hypertension, including pregnancy and preeclampsia.
Methods: Searches were conducted by two independent researchers in international (PubMed, Web of science, Scopus and Google scholar) and national (SID, Magiran) databases for related studies from the inception of the databases to September 2017 (without time limitation) in English and Persian languages. To ensure literature saturation, the reference lists of included studies or relevant reviews identifed through the search were scanned.
Discussion: The Hypertension Classification System was first introduced by the Terminology Committee of the American College of Obstetricians and Gynecologists. In this system, four main categories are considered for pregnancy hypertension, including pregnancy hypertension, preeclampsia or eclampsia, chronic hypertension, and preeclampsia in line with chronic hypertension.
Key words: Hypertensive, pregnancy, A Review
