Official title
Role of Aspirin in Maternal Endothelial Dysfunction and Uterine Artery Blood Flow in Women at Risk for Preeclampsia
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Endothelial dysfunction and defective placental vascularization are hypothesized to be significant causes of preeclampsia. In preeclampsia, due to vascular endothelial dysfunction, vasoconstriction and platelet activation can result in severe features which alter pregnancy outcomes. However, studies have shown that acetylsalicylic acid (Aspirin) can decrease endothelial dysfunction leading to decreased platelet aggregation which reduces adverse outcomes. The objective of our study is to determine if Aspirin has a dose-dependent response for modifying biomarkers reflective of maternal endothelial dysfunction when indicated for preeclampsia prevention in a cohort of women identified at risk for developing preeclampsia. Pregnant women who are at risk for preeclampsia will be randomized to receive either 81mg Aspirin or 162mg Aspirin daily starting from 11-16 weeks of gestation until 36 weeks of gestation. A third, control group of women at low risk for preeclampsia will not receive aspirin. All women will be assessed with uterine artery Doppler studies and mean arterial blood pressures at three time points during pregnancy. Blood, urine, and cord blood samples will also be collected.
