Study to Assess Safety and Efficacy of Treating Symptomatic, Ischemic, Chronic Congestive Heart Failure Patients with an LVEF of ≤40% with Fresh, Uncultured, Autologous, Adipose-derived Regenerative Cells Isolated from Lipoaspirate.

This study is testing whether injecting a patient's own fat-derived stem cells (harvested by liposuction) into the heart can improve function in people with chronic heart failure caused by blocked arteries. **You may be eligible if...** - You have coronary artery disease with documented heart damage and weak heart pump function (ejection fraction 40% or less) - You have been on stable heart failure medications for at least one month - You have mild-to-moderate heart failure symptoms (NYHA Class I, II, or III) - You are a candidate for a right-heart catheterization procedure **You may NOT be eligible if...** - You need heart bypass surgery, valve surgery, a mechanical heart pump, or a heart transplant - You had bypass surgery or a heart stent procedure in the last 3 months - You have significant valve disease or a history of stroke in the last 90 days - You have a pacemaker or defibrillator that is older than 2015 or has certain technical limitations incompatible with MRI - Your kidneys, blood counts, liver, or blood sugar are significantly impaired - You are HIV-positive or have active hepatitis B or C - You have had cancer in the past 3 years (except certain skin or cervical cancers) - You are pregnant or planning to become pregnant within 12 months Talk to your doctor to see if this trial is right for you.
