BACKGROUND Experimental data suggest that bone marrow-derived cells may contribute to the healing of myocardial infarction (MI). For this reason, we analyzed 10 patients who were treated by intracoronary transplantation of autologous, mononuclear bone marrow cells (BMCs) in addition to standard therapy after MI. METHODS AND RESULTS After standard therapy for acute MI, 10 patients were transpl...
Cell based therapy has been shown to attenuate myocardial dysfunction after myocardial infarction (MI) in different acute and chronic animal models. It has been further shown that stromal-cell derived factor-1α (SDF-1α) facilitates proliferation and migration of endogenous progenitor cells into injured tissue. The aim of the present study was to investigate the role of exogenously applied and e...
BACKGROUND Intracoronary delivery of autologous bone marrow mononuclear cells is an interesting therapeutic promise for patients with heart failure of different etiologies. AIM To evaluate the long-term safety and efficacy of this therapy in patients with dilated cardiomyopathy of different etiologies under optimal medical treatment. PATIENTS AND METHODS Prospective, open-label, controlled ...
Percutaneous coronary revascularization in patients with unstable angina and coronary thrombus carries a high complication rate. A new strategy to reduce thrombus burden before revascularization was tested in a multicenter prospective trial. Patients with unstable angina and coronary thrombus (n = 45) received alteplase through an infusion catheter at the proximal aspect of the target lesion an...
INTRODUCTION AND OBJECTIVES It is difficult to distinguish the effects early revascularization and regenerative therapy have on left ventricular function in patients with acute myocardial infarction (AMI). This study was an investigation into three groups of patients who had a revascularized anterior wall AMI and depressed left ventricular function (i.e., ejection fraction < 45%). The aim was t...
BACKGROUND Small and large preclinical animal models have shown that antagomir-92a-based therapy reduces early postischemic loss of function, but its effect on postinfarction remodeling is not known. In addition, the reported remote miR-92a inhibition in noncardiac organs prevents the translation of nonvectorized miR-targeted therapy to the clinical setting. We investigated whether a single int...
AIMS The objective of the present analysis was to systematically examine the effect of intracoronary bone marrow cell (BMC) therapy on left ventricular (LV) function after ST-segment elevation myocardial infarction in various subgroups of patients by performing a collaborative meta-analysis of randomized controlled trials. METHODS AND RESULTS We identified all randomized controlled trials com...
AIMS Clinical trials suggest that intracoronary delivery of autologous bone marrow-derived cells (BMCs) 1-7 days post-acute myocardial infarction (AMI) may improve left ventricular (LV) function. Earlier time points have not been evaluated. We sought to determine the effect of intracoronary autologous BMC on LV function when delivered within 24 h of successful reperfusion therapy. METHODS AND...
BACKGROUND Pilot trials suggest that the intracoronary administration of autologous progenitor cells may improve left ventricular function after acute myocardial infarction. METHODS In a multicenter trial, we randomly assigned 204 patients with acute myocardial infarction to receive an intracoronary infusion of progenitor cells derived from bone marrow (BMC) or placebo medium into the infarct...
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) ...
