Eligibility
Inclusion criteria
Inclusion criteria: 1. Having received intramyocardial bone marrow cell injection in study P02.051 (Injection of Autologous Bone Marrow Cells into Damaged Myocardium of No-option Patients with Refractory Angina Pectoris and Ischemia, a two-phased study of safety, feasibility and efficacy) or P05.025 (Efficacy assessment of intramyocardial injection of autologous bone marrow cells in no-option patients with refractory angina pectoris and documented ischemia, a randomized, double blind, placebo controlled study); 2. Disabling refractory angina pectoris despite optimal medical therapy; 3. Residual reversible ischemia on GATED-SPECT imaging; 4. No candidate for (repeat) revascularization; 5. Male or female, > 18 years old; 6. Patients must be stable and not be in a setting of life-threatening heart failure (LVEF>35%); 7. Able to perform an exercise tolerance test prior to therapy; 8. Able and willing to undergo all the tests used in this protocol including the traveling involved; 9. Written informed consent.
Exclusion criteria
Exclusion criteria: 1. Evidence of cancer (except low grade and fully resolved non-melanoma skin malignancy) as bone marrow cell infusion might promote tumor growth through induction of angiogenesis in the tumor; 2. Concurrent participation in a study using an experimental drug or an experimental procedure within 2 months before the injection procedure; 3. Other severe concurrent illnesses (e.g. active infection, aortic stenosis, renal failure); 4. Bleeding diathesis or HIV infection; 5. Any other condition that, in the opinion of the investigator, could pose a significant threat to the subject if the investigational therapy was to be initiated; 6. Inability to undergo cardiac catheterization or nuclear testing; 7. Inability to follow the protocol and comply with follow-up requirements; 8. Candidates for surgical of percutaneous intervention; 9. Mechanical aortic valve prosthesis.
Design outcomes

|---|---|
| The change in myocardial perfusion at 3 months follow-up relative to baseline. | — |
Secondary
| Measure | Time frame |
