Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is a double-blinded randomized-controlled trial in which patients will be randomized to 81 mg of aspirin or placebo to be continued for 6 weeks' postpartum. The purpose of this study is to compare NT-proBNP levels at the 4-6 week postpartum visit between groups. There is currently no data on the maternal health effects associated with continuation of low-dose aspirin in the postpartum period. This study aims to fill a gap in the knowledge regarding the utility of low-dose aspirin following delivery.

Participants Investigators
1:1 fashion to aspirin 81 mg vs identical-appearing placebo to be continued for 6 weeks' postpartum. Patients will receive these medications prior to hospital discharge. Both the patient and provider will be blinded to their assigned group. NT-proBNP levels will be drawn at the 4-6-week postpartum visit. NT-proBNP levels will be compared between groups.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Treatment Group

The treatment group will be provided with a 6-week supply of 81 mg of aspirin prior to discharge from the delivery admission. Patients will be scheduled for a 4-6 week postpartum clinic appointment, which is standard for these patients outside of this proposal.

Group Type ACTIVE_COMPARATOR

Aspirin 81Mg Ec Tab

Intervention Type DRUG

Participant may be provided with a 6-week supply of 81 mg of aspirin prior to discharge from the delivery admission.

Placebo Group

The control group will receive a 6-week supply of placebo medication from the Investigational Pharmacy prior to discharge. The placebo will be identically appearing to the 81 mg aspirin. Patients will be scheduled for a 4-6 week postpartum clinic appointment, which is standard for these patients outside of this proposal.

Group Type PLACEBO_COMPARATOR
