Detailed Description:

Severe ischemic heart disease remains a clinical challenge; many patients have undergone surgical myocardial revascularization procedures, but still remain symptomatic despite optimal medical therapy. Cell therapy with autologous bone marrow-derived cells (BMC) is a novel therapeutic strategy being tested for surgical treatment in patients with severe, chronic ischemic heart disease.

This research study is being performed to find out more information about the safety, feasibility, and efficacy of direct intramyocardial injection of autologous BMC on the myocardial perfusion and left ventricular function as an adjunctive therapy (compared to placebo) in patients undergoing coronary artery bypass surgery (CABG). The heart function evaluations will be performed by electrocardiogram, echocardiogram, and cMRI at baseline and during 6 months follow-up.

The secondary objective of this study is to assess the effect of intramyocardial injection of autologous BMC on functional class (angina/heart failure), global and cardiovascular mortality, and major adverse cardiac events after undergoing coronary artery bypass surgery.
