Hypertensive Disorders of Pregnancy.

Area of Science:

• Obstetrics and Gynecology
• Cardiovascular Medicine
• Maternal-Fetal Medicine

Background:

• Hypertensive disorders of pregnancy are a leading cause of maternal morbidity and mortality in the US.
• These disorders encompass chronic hypertension, gestational hypertension, preeclampsia, HELLP syndrome, eclampsia, and superimposed preeclampsia.
• They are associated with poor long-term maternal cardiovascular outcomes.

Purpose of the Study:

• To outline current management strategies for hypertensive disorders of pregnancy.
• To emphasize timely intervention for severe hypertension and postpartum monitoring.
• To highlight the role of aspirin prophylaxis in high-risk pregnancies.

Main Methods:

• Review of current clinical guidelines and evidence for managing hypertensive disorders in pregnancy.
• Discussion of treatment thresholds for chronic hypertension and management of gestational hypertension/preeclampsia without severe features.
• Emphasis on expeditious treatment for severe hypertension and postpartum surveillance.

Main Results:

• Initiate oral antihypertensive therapy for chronic hypertension at 140/90 mm Hg or greater.
• Manage gestational hypertension and preeclampsia without severe features with monitoring and delivery at 37 weeks.
• Expeditious antihypertensive therapy is vital for acute-onset severe hypertension; magnesium sulfate and antenatal corticosteroids are key for preeclampsia with severe features.

Conclusions:

• Hypertensive disorders of pregnancy require vigilant monitoring, especially postpartum, due to significant risks.
• Low-dose aspirin initiated between 12-16 weeks' gestation is effective for preeclampsia risk reduction in high-risk individuals.
• Management strategies vary based on severity and timing, with a focus on preventing maternal mortality and long-term complications.
