Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Low dose aspirin is sufficient to achieve complete inhibition of platelet aggregability, or stickiness, and this is the mechanism whereby aspirin prevents formation of blood clots.
Our research is designed to explore whether higher doses of aspirin provide additional benefits on markers of atherosclerosis.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Patients with stable coronary disease, with and without diabetes mellitus, defined by:
1. angiographic evidence of 70% or greater stenosis, or
2. previous percutaneous coronary intervention (PCI), or
3. coronary artery bypass graft (CABG), or
4. history of a MI, or
5. positive exercise test
Exclusion Criteria
2. Patients taking any of the following medications for less than 3 months, or who plan to take them for the first time during the next 3 months: ACE-inhibitors, angiotensin receptor blockers, calcium channel blockers, or statins.
3. Patients within 6 months of a coronary intervention, including PCI or CABG.
4. Patients with a planned coronary intervention.
5. Patients taking anti-platelet drugs such as clopidogrel or non-steroidal anti-inflammatory drugs (NSAIDs) or anticoagulant drugs such as warfarin.
6. Patients who are currently cigarette smokers.
7. Women patients who are pregnant, planning to become pregnant, nursing a child, or taking hormone replacement therapy.
8. Patients with any coagulation, bleeding or blood disorders.
9. Patients who are sensitive or allergic to aspirin.
10. Patients with documented history of any gastrointestinal disorders, including bleeding ulcers.
11. Patients with any evidence of cancer or kidney, liver, lung, blood, or brain disorders.
12. Patients with asthma, rhinitis, or nasal polyps.
13. Patients with any abnormal laboratory value or physical finding that, in the view of the responsible clinician, may interfere with interpretation of the trial results, be indicative of an underlying disease state, or compromise the safety.
14. Patients with Class IV heart failure.
15. Patients with severe aortic insufficiency, or aortic regurgitation.
16. Patients with hearing loss or tinnitus.
17. Patients with tremors which cause them not to be able to remain motionless for approximately 30 seconds.
