- Abstract
- Background Recently the potential of myocardial repair by transplantation of autologous bone marrow stem cells has been suggested. Whether the additional intracoronary transplantation of autologous peripheral blood stem cells (PBSC), which were mobilized by granulocyte-colony-stimulating factor (G-CSF), could safely improve myocardial function in patients with acute myocardial infarction (AMI) was investigated. Methods and Results Seventy-three patients with AMI who had successfully undergone percutaneous coronary intervention (PCI) were enrolled in the present prospective nonrandomized open-labeled study. Ten patients with elective PCI received G-CSF for 4 days followed by intracoronary PBSC transplantation. Thirty-two patients with primary PCI and 31 patients with recent AMI and elective PCI served as controls. The left ventricular (LV) function was evaluated using echocardiography and magnetic resonance imaging. G-CSF and intracoronary transplantation of PBSC did not incur any periprocedural myocardial damage. After 6 months, the LV ejection fraction was significantly improved in the cell therapy group. For 2 years of the follow-up period, there was no adverse clinical events, except one asymptomatic in-stent restenosis. However, comparable improvement of the LV ejection fraction was also identified in the primary PCI and elective PCI control groups. Conclusions In the present study, additional intracoronary infusion of PBSC was safe and feasible for the patients with AMI who had undergone PCI, but did not lead to a significant improvement in LV function compared to standard reperfusion treatment.
