Essential hypertension and pregnancy

Area of Science:

• Obstetrics and Gynecology
• Cardiology
• Maternal-Fetal Medicine

Background:

• Essential hypertension complicates approximately 1% of pregnancies.
• Pregnancy can lead to blood pressure stabilization or improvement in hypertensive patients.
• Antihypertensive medication is crucial for enhancing fetal survival in sustained hypertension.

Purpose of the Study:

• To review the management of essential hypertension during pregnancy.
• To highlight the importance of careful medication selection to avoid toxicity.
• To discuss the prediction and treatment of accelerated hypertension in pregnancy.

Main Methods:

• Review of prospective controlled studies on antihypertensive medication.
• Analysis of methods for predicting hypertension acceleration (maternal mean arterial pressures, intravascular volumes).
• Comparison of accelerated hypertension treatment with severe pre-eclampsia management.

Main Results:

• Antihypertensive medication significantly enhances fetal survival.
• Diuretics and salt restriction are contraindicated during pregnancy.
• Hypertension acceleration occurs late in pregnancy (2-11%) and can be predicted.
• Treatment for accelerated hypertension involves careful monitoring and early delivery.

Conclusions:

• Essential hypertension is not an absolute contraindication to pregnancy.
• Careful fetal and maternal monitoring can reduce fetal loss.
• Appropriate antihypertensive therapy and management strategies minimize risks.
