Cardiovascular disease is the leading cause of death in women. The hypertensive disorders of pregnancy (HDP) are the most common medical complication of pregnancy, complicating up to 10% of pregnancies worldwide. They represent a leading cause of maternal mortality and morbidity in pregnancy. The most common of these disorders is gestational hypertension (5–6%). Using population-based data, approximately 1% of pregnancies are complicated by pre-existing hypertension, 5–6% by gestational hypertension without proteinuria, and 1–2% by pre-eclampsia.
