Physiologic blood pressure patterns in pregnancies with mild chronic hypertension.

Objectives: To assess physiologic blood pressure (BP) changes throughout pregnancy in patients with mild chronic hypertension (CHTN) who do and do not develop preeclampsia (PEC), compared to patients with normal BP.

Study Design: Retrospective cohort of singleton gestations with CHTN at a single tertiary center from 2000 to 2014 and a randomly selected cohort of patients without CHTN and normal pregnancy outcomes (NML) in the same time period with BP measurements available <12 weeks gestational age.

Main Outcome Measures: The primary outcome was gestational age (GA) at nadir of systolic and diastolic BP.

Progression to Severe Chronic Hypertension 5-7 Years After a Pregnancy With Mild Chronic Hypertension.

Objective: To estimate the incidence of severe chronic hypertension (cHTN) within 5-7 years after a pregnancy complicated by mild cHTN.

Methods: This was a retrospective cohort study of women with mild cHTN during an index pregnancy between 2012 and 2014. Women were included if they received prenatal care at a single academic center and had mild cHTN during their pregnancy.
