Chinese Journal of Tissue Engineering Research 2013;(49):8557-8562
BACKGROUND:Number of experimental and clinical studies have shown that stem celltransplantation can establish new blood vessels and improve heart function instead of necrotic myocardium, to significantly improved clinical symptoms and prognosis of cardiovascular disease patients.
OBJECTIVE:To observe the safety of human umbilical cord blood mononuclear cells transplantation in patients with coronary heart disease and heart failure.
METHODS:A total of 12 patients with coronary heart disease and heart failure (acute myocardial infarction and heart failure in six cases, old myocardial infarction and heart failure in six cases) were enrol ed in this study. Patients were treated on the basis of standard medication and percutaneous coronary intervention. The coronary pathway was established via a percutaneous catheter, and suspension of cord blood mononuclear cells was injected through microcatheter into the distal artery. Routine blood test was carried out at 1 week after celltransplantation, blood routine, liver function, kidney function, C-reactive protein, IgA, IgG were compared preoperatively and postoperatively.
RESULTS AND CONCLUSION:The incidence of adverse reactions in cord blood stem celltransplantation was 8.3%, including one case of fever. No micro-embolism occurred. During 1-week fol ow-up, no graft-versus-host disease appeared. After celltransplantation, there were no significant changes in blood routine, liver function, kidney function, C-reactive protein, IgA, IgG. These findings indicate umbilical cord blood monomuclear cells transplantation is safe in a short term for patients with coronary heart disease and heart failure.
2.Intracoronary transplantation of autologous peripheral blood stem cells in old patients with acute myocardial infarction:5-year postoperative evaluation of cardiac function
Chinese Journal of Tissue Engineering Research 2014;(1):125-130
BACKGROUND:Myocardial infarction patients commonly appear to have left ventricular remodeling and heart failure. Because of physical characteristics, these two complications are more likely to occur in elderly patients with myocardial infarction. In recent years, stem celltransplantation in the treatment of acute myocardial infarction and heart failure has become a hot topic, and the feasibility and safety has been confirmed, but its long-term outcomes in elderly patients are stil unclear.
OBJECTIVE:To assess the long-term effect of transplantation of autologous peripheral blood stem cells on the left ventricular remodeling and heart function in the old patients with myocardial infarction.
METHODS:Thirty old patients (age ≥ 60 years) with myocardial infarction were randomly assigned to receive intracoronary transplantation of peripheral blood stem cells fol owing bone marrow cells mobilization by granulocyte colony-stimulating factor ( 300-600μg per day) subcutaneously for 5 days in addition to conventional therapy (standard drug therapy and percutaneous coronary intervention;transplantation group, n=15) or standard therapy (standard drug therapy and percutaneous coronary intervention;control group, n=15) . Complications during intervention, left ventricular function and left ventricular remodeling at baseline and 6, 12, 24, 60 months after treatment were monitored.
RESULTS AND CONCLUSION:Left ventricular function, left ventricular end diastolic volume, and left ventricular end-systolic volume were significantly improved 6,12, 24, 60 months after autologous peripheral blood stem celltransplantation compared to baseline, while these parameters remained unchanged in the control group. These parameters had statistical difference between the two groups after treatment. During the fol ow-up, no severe side effects were observed. These findings indicate that autologous peripheral blood stem celltransplantation leads to significant and longstanding improvements in left ventricular performance of old patients with myocardial infarction, and shows good safety.
