    Abstract:
    OBJECTIVE: To investigate the safety and efficacy of intracoronary transplantation of G-CSF mobilized autologous peripheral blood stem cells in patients with acute myocardial infarction (AMI). METHODS: Patients with AMI were randomly assigned to receive intracoronary PBSCs transplantation following bone marrow cells mobilization by granulocyte colony-stimulating factor (300-600 microg/day subcutaneously for 5 days) in addition to standard therapy (standard drug therapy and PCI, PBSCs transplantation group, n = 35) or standard therapy (standard drug therapy and PCI, n = 35). One day after G-CSF treatment was finished the patient's mononuclear cells were harvested by Baxter CS 3000 blood cell separator in a volume of 57 ml and then transferred into the infarct related artery by occluding the over the wire balloon and infusing artery through balloon center lumen. Complications during intervention and left ventricular function at baseline and 6 months thereafter were monitored. RESULTS: No severe side effects of G-CSF treatment could be observed. Malignant arrhythmias were not observed either. Left ventricular function was significantly improved 6 months after G-CSF mobilized autologous peripheral blood stem cell transplantation compared to baseline (global left ventricular function ejection fraction: 57.1 +/- 7.8 vs. 50.0 +/- 8.2%, P < 0.0001; WMSI: 1.101 +/- 0.118 vs. 1.219 +/- 0.190, P < 0.0001; left end-systolic volume: 52.6 +/- 20.3 vs. 63.8 +/- 23.9 ml, P = 0.01 and left end-diastolic volume: 119.2 +/- 30.3 vs. 134.2 +/- 36.7 ml, P = 0.07) while these parameters remained unchanged in the control group. CONCLUSION: The present study demonstrates that G-CSF mobilized autologous intracoronary PBSCs transplantation is a safe and feasible treatment for patients with AMI and global left ventricular function is improved and left ventricular remodeling attenuated at six-month follow-up.
