Mild gestational hypertension remote from term: progression and outcome

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Hypertensive Disorders of Pregnancy

Background:

• Mild gestational hypertension (GH) management lacks comprehensive prognostic data.
• Understanding disease progression in GH is crucial for expectant management strategies.
• Remote from term pregnancies with mild GH require careful monitoring.

Purpose of the Study:

• To describe prognostic signs in the natural course of mild gestational hypertension.
• To evaluate pregnancy outcomes in women expectantly managed for mild GH remote from term.
• To identify predictors of preeclampsia development and severity.

Main Methods:

• Prospective study of women with mild GH in an outpatient monitoring program.
• Inclusion criteria: singleton pregnancy, 24-35 weeks gestation, no proteinuria initially.
• Primary outcome: progression to preeclampsia; secondary outcomes: severe preeclampsia, obstetric and neonatal complications.

Main Results:

• 46% of women developed preeclampsia, and 9.6% progressed to severe preeclampsia.
• Development of proteinuria was associated with earlier gestational age at delivery (36.5 vs. 37.4 weeks).
• Proteinuria linked to lower birth weight (2752 vs. 3038 g) and increased small-for-gestational-age newborns (24.8% vs. 13.8%).

Conclusions:

• Expectant management of mild GH remote from term results in preeclampsia in 46% of cases.
• Proteinuria is a significant indicator of adverse pregnancy outcomes in mild GH.
• Early identification of proteinuria aids in managing risks associated with preterm delivery and fetal growth restriction.
