Bone Marrow Stem Cell Infusion Following a Heart Attack - Full Text View

Purpose

The goal of this study is to determine the safety of giving a patient's own bone marrow-derived stem cells delivered with a catheter (tube) into the coronary arteries (blood vessels of the heart). Stem cells are simple cells produced by the bone marrow that can develop into many types of cells. It is possible that these cells will decrease the size of damage caused to the heart from a heart attack and increase the pumping efficiency of the heart; which can be decreased due to a heart attack. The stem cells will be taken from bone marrow and then given back into the heart vessels.

Primary Outcome Measures:

Safety as measured by holter monitor, laboratory assessments, and cardiac MRI [ Time Frame: 6 months ]

Secondary Outcome Measures:

Improvement of left ventricular function as assessed by serial measurements of infarct size and LV function by cardiac MRI in the active treatment group versus placebo. [ Time Frame: 6 months ]

Study Completion Date:	September 2010
Primary Completion Date:	January 2010 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: Cell therapy Intracoronary, one time infusion of autologous, unfractionated bone marrow mononuclear cells.	Drug: Autologous, Unfractionated Bone Marrow Mononuclear Cells Intracoronary infusion of Autologous, Unfractionated Bone Marrow Mononuclear Cells. Dose is 100,000,000 cells. One time infusion over 20 minutes.

Detailed Description:

This protocol will test the hypothesis that an intracoronary infusion of autologous, unfractionated, bone marrow mononuclear cells will attenuate infarct size and improve left-ventricular function in 60 patients following an acute anterior myocardial infarction who have undergone successful revascularization with PTCA/stenting.

Eligibility

Criteria

Inclusion Criteria:
