Summary

This trial is examining if low dose aspirin therapy after pregnancy can help prevent cardiovascular disease in women who had preeclampsia during pregnancy.

Who is the study for?
This trial is for women aged 18 or older who had preeclampsia within the last 5 years. It's not suitable for those currently on daily aspirin, with skin diseases, using tobacco/nicotine, having liver/kidney disease, taking cholesterol or blood pressure meds, with a history of hypertension before pregnancy, gestational diabetes, currently pregnant, underweight (BMI <18.5), allergic to latex or study drugs, or with bleeding disorders and certain stomach issues.
What is being tested?
The study investigates if low dose aspirin therapy after pregnancy can prevent cardiovascular disease in women who've had preeclampsia by treating lasting blood vessel damage. Participants will either receive daily aspirin treatment or a placebo to compare effectiveness.
What are the potential side effects?
Aspirin may cause side effects like gastrointestinal upset including stomach pain and heartburn; increased risk of bleeding; allergic reactions; and possibly bruising more easily.
