When treating chronic hypertension during pregnancy, what role does low-dose aspirin play?

Low-dose aspirin is primarily used during pregnancy to reduce the risk of preeclampsia. Preeclampsia is a pregnancy complication characterized by high blood pressure and signs of damage to another organ system, most often the liver and kidneys. By taking low-dose aspirin, particularly for women identified as high-risk for preeclampsia, the incidence of this serious condition can be significantly decreased.

Research has shown that particularly in women who have had previous complications related to hypertension or preeclampsia, or who present with certain risk factors (such as chronic hypertension, diabetes, or obesity), the use of low-dose aspirin can be an effective preventive measure. It works by enhancing blood flow to the placenta and reducing the potential for vascular issues, hence mitigating the chances of developing preeclampsia.

While low-dose aspirin has various benefits and uses, its specific role as a preventive agent against preeclampsia is well-established and recognized in clinical guidelines for managing pregnant women at risk.
