• - History of stable angina.

• - Symptomatic peripheral arterial disease.

• - Prior MI, unstable angina, percutaneous coronary intervention, CABG, TIA, ischemic stroke, carotid endarterectomy, or other arterial surgery or angioplasty, which have occurred > 3 months prior to screening visit.

• - Diabetes Mellitus type 1 or 2 (considered a CV disease equivalent).

• - Clinical diagnosis of rheumatoid arthritis, as determined by individual patient and physician, requiring daily treatment with NSAIDs.

Exclusion Criteria:

Subjects with any of the following criteria will be excluded from this study: 1. Unstable angina, MI, CVA, CABG <3 months from screening visit. 2. Planned coronary, cerebrovascular, or peripheral revascularization. 3. Undergone major surgery within 3 months prior to screening visit or has planned major surgery during the study period. 4. Uncontrolled hypertension (SBP >190, DBP >100 mm Hg) during screening visit. 5. Uncontrolled arrhythmia < 3 months from screening visit. 6. NYHA class III-IV heart failure or if available, ejection fraction ≤ 35 % 7. Within 6 months prior to screening visit, a history of ACS or hospitalization for heart failure. 8. Oral corticosteroid, prednisone (or equivalent) > 20 mg daily. 9. Anticoagulation therapy. 10. Antiplatelet therapy except for aspirin. 11. GI ulceration < 60 days before screening visit. 12.

Allergy, allergic-type reactions or hypersensitivity (e.g. asthma, urticaria, etc.) to any of the study medications and its components (i.e. sulfonamides) 20. History of any disease of condition that, in the opinion of the investigator would place the subject at an unacceptable risk to participate in this study. 21. Any clinically relevant abnormal findings in physical examination, vital signs, or previous laboratory works that, in the opinion of the investigator, may compromise the safety of the subject to participate. 22. Subjects who are legally institutionalized. 23. Lactating females or females of childbearing potential except for those who are surgically sterile or postmenopausal-

The relative cardiovascular safety of NSAIDs, particularly among patients with cardiovascular disease (CVD) or at higher CVD risk, has generated considerable concern among both patients and physicians because of knowledge gaps in the evidence relative to comparative safety and pharmacodynamic interactions between aspirin and NSAIDs. In the recently reported PRECISION trial, a moderate dose of celecoxib was found to be noninferior to ibuprofen or naproxen with respect to cardiovascular safety in patients with arthritis at increased CVD risk. At this time, no comparative prior data are available analyzing the effects of NSAIDs vs.#46; Coxibs in the presence of aspirin on platelet function, biomarkers of inflammation and endothelial function. Thirty patients with rheumatoid arthritis who are at high cardiovascular (CV) risk or with established CV disease will be enrolled in the study. Patients taking anticoagulant therapy or any other antiplatelet agent other than aspirin will be excluded. Patients will be treated with immediate release 81mg aspirin for 4 weeks in the run-in period followed by randomization to celecoxib (200 mg bid) vs.#46; naproxen sodium (550 mg bid) for 4 weeks and then cross over to the other drug for another 4 weeks. Blood and urine samples will be collected at baseline before the aspirin run in period, 24±4 hr after the last dose of aspirin in the run in period, 24±4 hr after the last dose of the first period study drug and 24±4 hr after the last dose of the second period study drug. Assays for platelet function, biomarkers of inflammation and endothelial function will be performed at these time points.
