Association Between Gestational Hypertension and Risk of Cardiovascular Disease Among 617 589 Norwegian Women

BackgroundPreeclampsia and gestational hypertension (GH) are the most common hypertensive pregnancy disorders. Preeclampsia has been linked to increased risk of cardiovascular disease (CVD), but a similar association for GH has not been established. We aimed to determine the association between GH a...
