Eligibility Criteria
You may qualify if:
- Age 40 to 80 years, inclusive.
- Patients with stable coronary disease, with and without diabetes mellitus, defined by:
- angiographic evidence of 70% or greater stenosis, or
- previous percutaneous coronary intervention (PCI), or
- coronary artery bypass graft (CABG), or
- history of a MI, or
- positive exercise test
You may not qualify if:
- Patients taking greater than 81mg aspirin daily.
- 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.
- Patients within 6 months of a coronary intervention, including PCI or CABG.
- Patients with a planned coronary intervention.
- Patients taking anti-platelet drugs such as clopidogrel or non-steroidal anti-inflammatory drugs (NSAIDs) or anticoagulant drugs such as warfarin.
- Patients who are currently cigarette smokers.
- Women patients who are pregnant, planning to become pregnant, nursing a child, or taking hormone replacement therapy.
- Patients with any coagulation, bleeding or blood disorders.
- Patients who are sensitive or allergic to aspirin.
- Patients with documented history of any gastrointestinal disorders, including bleeding ulcers.
- Patients with any evidence of cancer or kidney, liver, lung, blood, or brain disorders.
- Patients with asthma, rhinitis, or nasal polyps.
- 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.
- Patients with Class IV heart failure.
- Patients with severe aortic insufficiency, or aortic regurgitation.

Limitations and Caveats
At the conclusion of the trial in 2010, due to lack of funds for analysis, we chose to analyze and report only the change in nitric oxide formation from baseline to 3 months.
