Criteria

Inclusion Criteria:

Subjects with ischemic cardiomyopathy and previous myocardial infarction
New York Heart Association Classification III - ambulatory Class IV
Ejection fraction < 35% as determined by any method at baseline evaluation
Subjects could be considered for enrollment if CRT placement has occurred greater than three months previously with no clinical improvement, CRT settings are judged to be optimized and the subject continues to meet all other inclusion criteria (inadequate-responders).
Documentation of ineligibility for coronary revascularization and/or valve repair/ replacement by review of recent left heart catheterization (within six months of baseline).
Receiving optimally tolerated doses of standard, stable pharmacotherapy, including angiotensin-converting enzyme inhibitors, unless intolerant or contra-indicated, diuretics, ß-receptor blockers for at least one month prior to enrollment
Severe myocardial perfusion abnormality documented by SPECT imaging, involving at least 1/3 of a vascular territory, as confirmed by core lab.

Exclusion Criteria:

Age < 21 years or > 75 years.
Significant coronary stenosis, as determined by the Investigator, which may potentially require percutaneous or surgical revascularization within 12 weeks of enrollment.
Recent (within 4 weeks), documented acute coronary syndrome, i.e. (Q wave or non-Q wave infarction) or hospitalization for unstable angina.
Documented cerebrovascular accident (stroke) or TIA within 60 days.
Left ventricular thrombus (mobile or mural-based) as evidenced by ventriculogram or echocardiography.
Clinically significant electrocardiographic abnormalities that may interfere with subject safety during the intracardiac mapping and injection procedure. Patients with right bundle branch block with basal septal infarction.
Subjects with CRT placement within three months of enrollment or intent to insert CRT, or CRT settings not judged to be optimized
High grade atrioventricular block not corrected by permanent pacemaker or ICD.
Frequent or recurrent, ventricular tachycardia in absence of an ICD.
Atrial fibrillation with uncontrolled ventricular response
Significant uncorrected valvular disease, which results in additional hemodynamic compromise and/or would require valvular repair or replacement. Patients with severe aortic stenosis or status-post mitral or aortic mechanical valve replacement.
Severe peripheral vascular disease, such that femoral access would be prohibited.
INR > 1.5 in absence of coumadin or partial thromboplastin time (PTT) >20% above ULN, or thrombocytopenia (platelet count < 75,000).
Significant renal dysfunction (e.g., creatinine >2.5 mg/dL) or liver disease (e.g., serum glutamic-oxaloacetic transaminases / aspartate aminotransferase SGOT/AST or serum glutamic-pyruvic transaminases/alanine aminotransferase SGPT/ALT > 4 x upper limit of normal [ULN]).
Currently enrolled, or have been enrolled within 30 days, in another investigational drug or device study that has not completed the protocol required follow-up period.
Subjects who have received a prior investigational stem cell or angiogenic agent.
Subjects who have tested positive for Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HBV), and/or Hepatitis C Virus (HCV).
History of skeletal muscle disease, e.g. family history of acute or chronic skeletal muscle disease including infectious, drug-induced, familial, autoimmune and idiopathic myopathies.
Creatine phosphokinase (CK) or lactate dehydrogenase elevated greater than three times normal or unexplained elevations of CK.
Female subjects who are pregnant or nursing or any subject with reproductive capabilities unwilling to use effective birth control for the duration of the study period.
Evidence of concurrent infection of any type (e.g. Elevated white blood cell count {WBC>13,000}, temperature of >38.5 C, or infiltrate on chest x-ray).
Any other major illness, which, in the Investigator's judgment, will interfere with the subject's ability to comply with the protocol, compromises subject safety, or interferes with the interpretation of the study results.
Idiopathic Cardiomyopathy, hypertrophic cardiomyopathy
Subjects with ventricular wall thickness in the infarct zone of < 5 mm measured by echocardiogram at baseline.
Patients on chronic (or chronic intermittent) IV inotropic medication. -
