Brief Summary
The purpose of this study is to determine if stem cell therapy with your own cells (autologous cells) delivered with a catheter to regions of the heart with poor blood flow will be safe and if it will relieve your chest pain, increase the blood flow, and/or improve the cardiac contractility (function) by regenerating blood vessels in your heart.

Interventions
Eligibility Criteria
You may qualify if:
- At least 6 months since last episode of myocardial infarction or at least 3 months since initial anginal episode.
- Patients fulfilling either of the following criteria based on the extent of CAD by coronary angiography and LVEF by echocardiography.
- Patients with single vessel CAD and LVEF \< 50%
- Patients with multivessel CAD
- Reversible myocardial ischemia as revealed by sestamibi SPECT stress myocardial scintigraphy.
- Patients for whom angioplasty and bypass are not indicated because of anatomical or procedural reasons or frequent reocclusion/restenosis following traditional revascularization.
- Age is between 20 and 80 (at time of consent).
- Exercise tolerance time (ETT) duration ≥ 3 minutes and \< 13 minutes on a modified Bruce protocol on 2 consecutive tests (\> 24 hours but \< 2 weeks apart), with the difference between the 2 exercise times within 25% of their mean (Patients should not be informed of exercise restrictions required for entry into the study).
- Patients who can give informed consent themselves in writing.
You may not qualify if:
- Sustained ventricular tachycardia in a 24-hour ECG.
- Chronic atrial fibrillation.
- Less than 6 months since last episode of cerebral infarction.
- Less than 6 months since last coronary angioplasty or less than 3 months since last bypass surgery.
- Patients with unstable angina, with a treatment rating of 3 in the Braunwald system (refer to 5.4.), but a severity of III and a clinical rating of B or C.
- Presence of left ventricular thrombus by echocardiography
- Patients with a malignant tumor\*.
- Patients with diabetic proliferating retinopathy\*\* (new Fukuda classification BI to BV).
- Patients with chronic rheumatoid arthritis.
- Patients with a history of severe allergic reactions or side effects to G-CSF preparations or apheresis.
- Patients with hematological disease (leukemia, myeloproliferative disease, or myelodysplastic syndromes).
- Patients currently suffering from or having a history of interstitial pneumonitis.
- Patients for whom cranial MRA reveals cerebral aneurysm.
- Patients for whom abdominal CT or ultrasonography reveals splenomegaly.
- Patients with cirrhosis of the liver.
