Stem Cell Study for Subjects With Congestive Heart Failure

March 30, 2015 updated by: Losordo, Douglas, M.D.

Injection of Autologous CD34+ Cells for Neovascularization and Symptom Relief in Patients With Myocardial Ischemia and LVEF < 40%

The purpose of this study is to determine if 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 improve your ejection fraction and heart failure symptoms.

Description

Inclusion Criteria:

  • Subjects 21 to 80 years old (inclusive).
  • Subjects with functional class (NYHA) II or III ischemic heart failure.
  • Subjects who have attempted "best" cardiac medical therapy including long-acting nitrates, maximal use of beta-adrenergic blocking agents, and angiotensin-converting enzyme (ACE)inhibitors without control of symptoms.
  • Subjects must be identified as non-candidates for conventional revascularization by their referring cardiologist.
  • Subjects must have left ventricular ejection fraction <40% by echocardiography.
  • All subjects must have a recent coronary angiogram (within the last 6 months) to document the coronary anatomy and insure the presence of coronary disease that is not amenable to standard revascularization procedures.
  • Have serum B-type Natriuretic Peptide (BNP) level >100 pg/ml.

Exclusion Criteria:

  • Myocardial infarction (Q wave or non-Q wave defined as CKMB >3 times normal) within 30 days of treatment.
  • Successful coronary revascularization procedures within 3 months of study enrollment.
  • Documented stroke or transient ischemic attack (TIA) within 60 days of study enrollment.
  • NYHA Class IV heart failure and patients with idiopathic or non-ischemic heart failure.
  • History of severe aortic stenosis (aortic valve area < 1.0 cm2) or insufficiency (>2+); severe mitral stenosis (mitral valve area <1.5 cm2); or severe mitral insufficiency(>2+).
  • Implantation of biventricular pacemaker within 90 days of study treatment.
  • Severe co-morbidity associated with a reduction in life expectancy of less than 1 year, such as chronic medical illness (i.e. severe chronic obstructive pulmonary disease, renal failure or cancer).
