Autologous bone marrow stem cell transplantation in acute myocardial infarction-report of two cases.

The results of numerous experimental and clinical studies evaluating transplantation of bone marrow-derived pluripotential stem cells into the area of postinfarction myocardial injury, including direct myocyte precursors, are very encouraging. We have previously reported our clinical experience with transplantation of autologous skeletal myoblasts in the treatment of postinfarction myocardial injury. Currently, we report on two cases of intracoronary autologous bone marrow - derived CD34+ stem cells transplantation during acute phase of myocardial infarction. Lack of major procedural complication and expected benefits resulting from myocardial regeneration justify the initiation of a clinical study evaluating the use of this method in the treatment of patients with myocardial infarction. Our current report is only a method description and the two first cases presentation, indicating its feasibility - evaluation of the efficacy requires future investigations.
