The purpose of this study is to investigate the safety of intracoronary cardiac stem cells (CSCs) therapy in humans. Currently, there is no effective intervention to regenerate (regrow) dead heart muscle after a heart attack. The central hypothesis is that CSCs infused into nonviable myocardial segments will regenerate infarcted myocardium by differentiating into cardiomyocytes and other cell types. According to our hypothesis, CSC infusion regenerates myocardium with consequent improvement in contractile function of the heart and general clinical status.
