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.

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.
