Using low-dose aspirin early in pregnancy to prevent preeclampsia and miscarriage

Early Double Low-Dose Aspirin to Reduce Preeclampsia and Miscarriage: a Global Approach RCT

NIH-funded research University of Pennsylvania · NIH-10901882

This study is looking at whether taking a low dose of aspirin right after you find out you're pregnant can help prevent serious issues like preeclampsia and miscarriage, and it's for anyone who just got a positive pregnancy test.

What this research studies

This research investigates the effects of starting low-dose aspirin therapy at the very beginning of pregnancy to see if it can help prevent serious complications like preeclampsia and miscarriage. Participants will be recruited through early pregnancy tests, allowing for timely intervention. The study will compare the outcomes of those taking a higher dose of aspirin daily from the first positive pregnancy test against those who do not. This approach aims to gather high-quality evidence on the benefits of early aspirin use in a diverse group of pregnant individuals.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals who have recently confirmed a pregnancy and are within the first trimester.

Not a fit: Patients who are not pregnant or those who have contraindications to aspirin use may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could significantly reduce the rates of preeclampsia and miscarriage, improving outcomes for pregnant individuals and their babies.

How similar studies have performed: Previous research has shown that aspirin can be beneficial in preventing preeclampsia when started later in pregnancy, but this approach of early initiation with a higher dose is novel.
