Ischemic Congestive Heart Failure
Conditions
Keywords
CHF, ischemia, Heart Failure
Brief summary
The intent of this clinical study is to answer the questions: 1. Is the proposed treatment safe 2. Is treatment effective in improving the disease pathology of patients with Heart Disease as assessed by a series of measurements indicating improvement, stability, or degradation of a patient's cardiovascular function and exercise capacity?
Detailed description
This will be an open-label, non-randomized, multi-center patient-sponsored study designed to assess the safety and cardiovascular effects of Adipose-derived Stem Cell (ASC) implantation using a catheter delivery system in patients who have experienced myocardial infarction. A percutaneous transluminal endomyocardial injection catheter will be used for delivery of ASCs. The therapy is composed of cells isolated from a patient's own adipose tissue. Liposuction will be performed to collect the adipose tissue specimen for subsequent processing to isolate the stem cells.
Interventions
PROCEDUREFat Harvesting and Implantation of Adipose Derived Stem Cells
Local Liposuction will be performed to harvest the fat. The Adipose Derived Stem Cells will be implanted via intramyocardial injection and intravenously.

Aortic aneurysm or dilatation (\>3.8 cm by echocardiography or other imaging modality) 7. Peripheral vascular disease at or below the distal aorta that may interfere with catheter use 8. Hemodynamically significant pericardial disease 9. Prior aortic or mitral valve replacement 10. Biventricular pacing device implant within the last 3 months OR whose device is scheduled to be revised following enrollment in this trial 11. Scheduled to receive or history of cardiac transplant, surgical remodeling procedure, left ventricular assist device 12. Stroke within 180 days of screening 13. Positive pregnancy test in women of child bearing potential or who are unwilling to use an acceptable method of contraception. 14. Drug or alcohol dependence 15.

Exposure to angiogenic therapy (including myocardial laser) or another investigational drug within 60 days of screening, or enrollment in any concurrent study that may confound the results of this study 18. Any factors in the opinion of the Investigator which render the patient unsuitable for participation that will interfere with conduct of the study or interpretation of the results.
