Blood pressure change in normotensive, gestational hypertensive, preeclamptic, and essential hypertensive pregnancies.

ABSTRACT: We compared patterns of blood pressure (BP) change among normotensive women, women who developed gestational hypertension or preeclampsia, and women who had essential hypertension to examine how distinct these conditions are and whether rates of BP change may help to identify women at risk for hypertensive disorders. We used antenatal clinic BP measurements (median, 14 per woman) of 13016 women from the Avon Longitudinal Study of Parents and Children who had a singleton or twin live birth surviving until ≥ 1 year. Linear spline models were used to describe changes in systolic and diastolic BPs in different periods of pregnancy (8-18, 18-30, 30-36, and ≥ 36 weeks' gestation). Women who had essential hypertension and those who developed gestational hypertension or preeclampsia had higher BP
