Hypertension in pregnancy.

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Cardiovascular Health in Pregnancy

Background:

• Hypertension in pregnancy is a major cause of maternal and neonatal morbidity and mortality.
• Preeclampsia-eclampsia poses the greatest risk, while chronic hypertension can lead to preterm birth and small for gestational age infants.
• Chronic hypertension is also a risk factor for superimposed preeclampsia, increasing adverse outcomes.

Purpose of the Study:

• To review the impact of different hypertensive disorders in pregnancy.
• To discuss the pathophysiology of preeclampsia, including placental perfusion abnormalities and endothelial dysfunction.
• To examine the challenges and lack of consensus in pharmacologic therapy for mild-to-moderate hypertension during pregnancy.

Main Methods:

• Literature review and synthesis of existing research on hypertensive disorders in pregnancy.
• Analysis of the contributing factors and consequences of preeclampsia and chronic hypertension.
• Discussion of current therapeutic guidelines and controversies in managing hypertension during pregnancy.

Main Results:

• Preeclampsia-eclampsia is the most impactful hypertensive disorder, linked to multiorgan failure.
• Minority ethnicity and socioeconomic disadvantage are associated with higher preeclampsia incidence.
• Pharmacologic therapy for mild-to-moderate hypertension in pregnancy lacks consensus due to safety considerations.

Conclusions:

• Hypertensive disorders in pregnancy necessitate careful management due to significant risks.
• Preeclampsia's complex etiology and impact highlight the need for further research.
• The safety and efficacy of treating mild-to-moderate hypertension in pregnancy require further investigation and consensus building.
