Perinatal implications of maternal hypertension

Area of Science:

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

Background:

• Hypertensive disorders of pregnancy (HDP) are common and associated with reduced uteroplacental blood flow.
• These conditions include chronic hypertension, preeclampsia-eclampsia, superimposed preeclampsia, and gestational hypertension.
• Pathophysiology involves impaired placentation and abnormal vasomotor regulation, potentially involving the uterine renin-angiotensin system.

Purpose of the Study:

• To review the pathophysiology of hypertensive disorders of pregnancy.
• To explain the clinical manifestations based on circulatory effects.
• To describe perinatal implications and antenatal assessment strategies.

Main Methods:

• Literature review of pathophysiology, clinical manifestations, and perinatal outcomes.
• Explanation of clinical findings based on vasoconstriction and ischemia.
• Brief overview of antenatal assessment and management principles.

Main Results:

• HDP are characterized by deficient uterine vascular modeling and altered vasomotor tone.
• Clinical signs result from systemic and regional vasoconstriction and ischemia.
• Adverse perinatal outcomes include immediate neonatal issues and long-term neurodevelopmental effects.

Conclusions:

• Hypertensive disorders of pregnancy significantly impact maternal and fetal health.
• Understanding pathophysiology is crucial for managing these conditions.
• Effective antenatal assessment and management are vital for improving outcomes.
