Abstract：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. <br> OBJECTIVE:To observe the safety of human umbilical cord blood mononuclear cells transplantation in patients with coronary heart disease and heart failure. <br> 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. <br> 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.
