Aspirin vs. Clopidogrel for Chronic Heart Artery Disease
Treatments studied
Part of Heart & circulation clinical trials.
This study compares two blood-thinning medications—aspirin and clopidogrel—in people with chronic coronary artery disease (narrowed heart arteries). Researchers want to learn which medication works better at preventing heart problems over 5 years.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Age 18 or older
- Documented significant narrowing of heart arteries (≥50% in main artery or ≥70% in other arteries, confirmed by angiogram or special tests)
- At least 6 months have passed since your last heart attack or acute coronary event
- No allergy to aspirin or clopidogrel
- Able and willing to stay in the study area and attend all visits for up to 5 years
- Not taking certain medications that interact with clopidogrel (blood thinners like warfarin, certain antidepressants, or others)

This trial tests whether a lower dose of aspirin combined with another blood thinner (prasugrel) after bypass surgery is as safe and effective as a higher dose. It is for people with stable heart disease who are scheduled for bypass surgery and have not had a recent heart attack.
This trial compares two common “blood thinner” combinations to prevent problems after a PCI procedure for complex blocked heart arteries. It may help your care team find which combination works better for people with higher-risk artery patterns.
This trial tests whether daily aspirin is safe and effective for people who have stable (chronic) coronary artery disease but cannot have procedures to open blocked arteries. It may help reduce future heart problems, while also checking for side effects and risks from aspirin.
This trial tests whether clopidogrel (a blood-thinning medicine) can prevent future heart attacks or strokes in people who have early, “subclinical” plaque in their heart arteries. You may be considered if scans show plaque but not major artery blockage that needs a procedure.
This study looks at how anti-platelet medicines like aspirin and clopidogrel work in people with hardened arteries (atherosclerosis) or peripheral artery disease (PAD). The goal is to understand how these drugs affect your body's clotting system.
This trial tests whether taking just one blood thinner (clopidogrel) is as safe and effective as taking two (clopidogrel plus aspirin) for older adults or people at high bleeding risk who have had a drug-coated balloon procedure to open blocked heart arteries.
