New screening could stop dangerous pregnancy condition before it starts
NCT ID NCT07485140
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to see if a new screening program during the first trimester can better identify pregnant women at risk for preeclampsia—a condition causing high blood pressure that can harm both mother and baby. Up to 80,000 women in Denmark will take part. Those found to be high risk will be offered daily low-dose aspirin to help prevent the condition. Researchers will compare rates of preterm preeclampsia before and after the program is introduced.
