Summary
Preeclampsia affects 10% of pregnancies with hypertension, stemming from placental issues. Early diagnosis and aspirin may prevent severe maternal and fetal complications.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Cardiovascular Disease in Pregnancy
Context:
- Hypertension complicates 10-15% of pregnancies.
- Preeclampsia, a severe form, affects only 10% of hypertensive pregnancies.
- Pathophysiology involves placental implantation anomalies leading to systemic effects.
Purpose:
- To outline the pathophysiology, diagnosis, and management of preeclampsia.
- To highlight maternal and fetal complications associated with hypertensive disorders in pregnancy.
- To discuss the role of antihypertensive treatment and aspirin prophylaxis.
Summary:
- Preeclampsia arises from placental implantation defects, triggering a cascade of vasoactive and hemostatic anomalies.
- Diagnosis relies on hypertension (≥0.5 g/24 h proteinuria) and requires monitoring for maternal (e.g., HELLP syndrome, eclampsia) and fetal (e.g., growth restriction) complications.
- Treatment aims to normalize blood pressure and prevent severe outcomes; aspirin prophylaxis can reduce recurrent preeclampsia and fetal growth restriction.
Impact:
- Improved understanding of preeclampsia's complex pathophysiology.
- Enhanced diagnostic criteria and monitoring protocols for hypertensive disorders in pregnancy.
- Evidence-based strategies for treatment and prevention, including aspirin's role in reducing adverse outcomes.
