Summary

This study will measure blood levels of endothelial progenitor cells (EPCs) and nitric oxide (NO) in patients with coronary artery disease (CAD) who are participating in a 3-month cardiac rehabilitation program at Suburban Hospital in Bethesda, MD. EPCs are a kind of stem cell produced by the bone marrow that can develop into cells found in arteries and in the heart and, therefore, can repair diseased vessels. The study will examine whether the EPCs are affected by exercise and will look at how they may contribute to repair of cells lining the diseased arteries as a result of participation in the rehabilitation program.

People with coronary artery disease may be eligible for this study. Candidates are screened with a medical history, physical examination, electrocardiogram, and blood tests. CAD patients also to a treadmill exercise test.

Volunteers' participation ends at the screening visit. The blood drawn at screening is used to identify EPC specific genes to compare with the EPC genes from patients with CAD.

CAD patients participate in Suburban Hospital's cardiac rehabilitation program. The exercise portion of the program includes 36 sessions of about 60 minutes each, spaced over approximately 3 months. Patients have a baseline blood test at screening and repeat blood tests at the end of each month of participation in the rehabilitation program. Some of the blood will be used for genetic tests to see how genes of the EPCs are changed by the patient's participation in the rehabilitation program.
