Is this trial a fit for you?

Likely a good fit

Ideal candidates are pregnant women aged 18 to 45 diagnosed with preeclampsia and presenting for delivery with a singleton gestation.

Probably not a fit

Patients with preexisting heart conditions, multiple gestations, or those who are in labor will not benefit from this study.

What this trial studies

This clinical trial investigates the effects of aspirin therapy on postpartum cardiac function in women diagnosed with preeclampsia. It is a single-center, double-blind, randomized, placebo-controlled trial that focuses on patients with elevated Activin A levels, which are associated with increased risk of cardiac dysfunction. Participants will undergo blood tests to measure Activin A levels and will be randomized to receive either aspirin or a placebo after delivery. The goal is to determine if aspirin can effectively lower Activin A levels and improve cardiac function in this high-risk population.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the risk of cardiac complications in postpartum women with preeclampsia.

How similar studies have gone: While studies on aspirin for various conditions exist, this specific approach targeting postpartum cardiac dysfunction in preeclampsia is novel and has not been extensively tested.
