Pilot study, investigates the effects of "acute" exercise on PGE levels as measured by CORUS CAD score.
|Ages Eligible for Study:
||45 Years to 75 Years
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
Acute exercise, exercise stress test affect the peripheral gene expression levels of the 23 genes in the CORUS CAD algorithm and the time frame at which, gene levels change.
- Ages 45-75 years old
- Able to perform an adequate exercise stress test
- Subjects with no known CAD and subjects with known CAD subjects
- Known severe CAD that will be unsafe to exercise stress patient
- Current MI or high-risk acute coronary syndrome (including high-risk unstable angina
- NYHA class III or IV congestive heart failure
- Severe regurgitant or stenotic cardiac valvular lesion
- Severe left ventricular systolic dysfunction
- Active systemic infection in the preceding 2 months or chronic infection (e.g. HIV, Hepatitis B or C, Tuberculosis)**.
- Protocol-specified rheumatologic, autoimmune or hematologic conditions
- Known or suspected diabetes mellitus or documented Hemoglobin A1C (A test for people with diabetes that monitors their average blood sugar levels over a period of two to three months) percent within last 6 months; presume normal HgbA1c (used as a standard tool to determine blood sugar control for patients with diabetes.) if none documented.
- Total WBC 11,000/ul from a CBC drawn within 7 days of enrollment
- Inadequate exercise stress test.
- Recipient of any organ transplant
- Immunosuppressive or immunomodulatory therapy including any dose of systemic corticosteroids in the preceding two months
- Chemotherapy in the preceding year
- Major surgery in the preceding 2 months
- Blood or blood product transfusion in the preceding 2 months
