Risk of Cardiovascular Disease in Women With a History of Hyperemesis Gravidarum, With and Without Preeclampsia.

Background Hyperemesis gravidarum is associated with preeclampsia, but it is unclear whether hyperemesis gravidarum is a risk factor for cardiovascular disease. We assessed the long-term risk of cardiovascular disease in women who experienced hyperemesis gravidarum with or without preeclampsia. Methods and Results We analyzed a longitudinal cohort of 1 413 166 pregnant women in Quebec between 1989 and 2021.
