NCT01049867

Brief Summary

The aim of this study is to evaluate if the intracoronary infusion of autologous bone-marrow derived CD133+ endothelial precursor cells is able to promote neovascularization and to improve myocardial perfusion and contractility in patients with refractory coronary heart disease, characterized by poor response to standard coronary interventions, severe impairment of the quality of life, and poor prognosis.
