safety and efficacy of adipose derived stem cells for congestive heart failure

Conditions: Ischemic Congestive Heart Failure

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?

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.
