Pilot project on treating hypertension during pregnancy

Treatment of American Heart Association/American College of Cardiology Stage 1 Hypertension in Pregnancy: A Randomized Control Trial

Phase 1 Interventional University of Alabama at Birmingham · NCT05989581

This study is testing if treating high blood pressure earlier in pregnant women can help improve their baby's birth weight compared to usual care.

What this trial studies

The CHAP2 pilot project aims to gather preliminary data for a larger multicenter study focused on the treatment of stage 1 hypertension in pregnant women. This study will randomize participants to either a treatment group aiming for blood pressure below 130/80 mmHg or a usual care group, where treatment is only initiated if blood pressure reaches 140/90 mmHg. The primary goal is to assess whether achieving lower blood pressure targets can positively influence birthweight percentiles at delivery. A total of 74 eligible participants will be enrolled in this pilot study at UAB Hospital.

Who should consider this trial

Good fit: Ideal candidates are pregnant women with stage 1 hypertension planning to deliver at UAB Hospital.

Not a fit: Patients with chronic hypertension or those requiring more stringent blood pressure control will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved maternal and neonatal outcomes for pregnant women with stage 1 hypertension.

How similar studies have performed: While this pilot project is novel in its specific approach, similar studies have shown promise in managing hypertension during pregnancy.
