Daily baby aspirin is recommended for patients at risk of preeclampsia based on which condition?

Daily baby aspirin is recommended for patients at risk of preeclampsia primarily due to a history of previous preeclampsia. Research indicates that women who have experienced preeclampsia in earlier pregnancies are at an increased risk of developing the condition again in subsequent pregnancies. The use of low-dose aspirin has been shown to reduce the risk of recurrence in these patients by improving uteroplacental blood flow and reducing inflammation, which are contributing factors to the development of preeclampsia.

While multiple pregnancies, chronic hypertension, and insulin resistance are all factors that can elevate the risk of preeclampsia, they do not carry the same level of established recommendation for aspirin prophylaxis as does a prior history of preeclampsia. Consequently, the evidence specifically supports the use of daily baby aspirin for those with a previous experience of the condition to mitigate the risk in future pregnancies.
