Preventing the development of preeclampsia in high-risk patients could theoretically decrease the risk of eclampsia and its complications later in pregnancy. Aspirin blocks platelet aggregation and vasospasm in preeclampsia, and it may be effective in preventing preeclampsia. Studies have shown that low-dose aspirin in women at high risk for preeclampsia can contribute to a decreased risk of preeclampsia, a reduction in preterm delivery rates, and a reduction in fetal death rates, without increasing the risk of placental abruption. An obstetrician should directly supervise low-dose aspirin therapy in high-risk patients.
