OBJECTIVES: Ischaemic heart disease remains a major cause of death in Japan. We have implanted autologous bone marrow-derived cells locally into the ischaemic region as a therapy in addition to coronary artery bypass grafting since 1999. We describe the outcomes of our cell therapy for ischaemic heart disease. METHODS: Eleven patients underwent local implantation of bone marrow-derived cells into the ischaemic region during coronary artery bypass grafting. Clinical outcomes during the acute and chronic phases were recorded. RESULTS: In the acute phase, no adverse effects were observed. Left ventricular ejection fraction values were not significantly different before and after treatment. Seven of the 11 patients showed improved blood perfusion in the area of cell therapy 1 month after treatment. In the chronic phase, 5 of 11 patients exhibited improved regional blood flow 1 year after treatment. Overall survival at 1, 5 and 10 years was 100%, 83.3% and 83.3%, respectively. Freedom from major adverse cardiac and cerebrovascular events at 1, 5 and 10 years was 100%, 80.8% and 80.8%, respectively. Death from all causes or freedom from major adverse cardiac and cerebrovascular events at 1, 5 and 10 years was 100%, 64.6% and 64.6%, respectively. CONCLUSIONS: Local implantation of bone marrow-derived cells in patients with ischaemic heart disease is safe and feasible. Cell therapy is a therapeutic option for otherwise untreatable ischaemic heart disease.
