CONTEXT Previous studies have suggested that bone marrow cell injection may improve myocardial perfusion and left ventricular (LV) function in patients with chronic myocardial ischemia. OBJECTIVE To investigate the effect of intramyocardial bone marrow cell injection on myocardial perfusion and LV function in patients with chronic myocardial ischemia. (More)
Stem cell therapy has emerged as a potential therapeutic option for cell death-related heart diseases. Preclinical and a number of early phase human studies suggested that cell therapy may augment perfusion and increase myocardial contractility. The rapid translation into clinical trials has left many issues unresolved, and emphasizes the need for specific(More)
Bone marrow cell transplantation has been proposed as a novel therapeutic option for patients with coronary artery disease. This study investigated whether autologous bone marrow-derived mononuclear cell injection into the ischemic myocardium of patients with severe angina pectoris could safely reduce anginal symptoms, improve myocardial perfusion, and(More)
UNLABELLED Intramyocardial injection of bone marrow cells has been proposed as a new therapeutic option for patients with chronic ischemic heart disease. We investigated whether autologous bone marrow-derived mononuclear cell injection into the myocardium of patients with drug-refractory ischemia reduces anginal symptoms, improves left ventricular (LV)(More)
OBJECTIVES We evaluated whether human adult bone marrow-derived mesenchymal stem cells (hMSCs) could repair an experimentally induced conduction block in cardiomyocyte cultures. BACKGROUND Autologous stem cell therapy is a novel treatment option for patients with heart disease. However, detailed electrophysiological characterization of hMSCs is still(More)
The present study investigated the safety, feasibility, and potential efficacy of autologous bone marrow cell injection in patients with chronic myocardial infarction and severe left ventricular (LV) dysfunction. In 15 patients (63 +/- 9 years; 14 men) bone marrow was aspirated from the iliac crest. Using the NOGA system (Biosense-Webster, Waterloo,(More)
BACKGROUND Cell therapy has recently been introduced to treat patients with refractory angina. Because most studies have only included short-term follow-up, the effects of cell therapy over a longer period are unknown. METHODS In 25 patients (mean age 64 +/- 10 years, 21 men) with refractory angina, a total of 84 +/- 29 x 10(6) bone marrow-derived(More)
PURPOSE To evaluate the effect of intramyocardial bone marrow cell injection on diastolic function in patients with chronic myocardial ischemia. MATERIALS AND METHODS In 24 patients (19 male; 65 +/- 9 years) with refractory angina (Canadian Cardiovascular Society [CCS] class III-IV) 84.6 +/- 28.7 x 10(6) bone marrow-derived mononuclear cells were injected(More)
BACKGROUND Intramyocardial bone marrow cell injection is associated with improvements in myocardial perfusion and anginal symptoms in patients with refractory angina pectoris. This study evaluates the effect of repeated intramyocardial bone marrow cell injection in patients with residual or recurrent myocardial ischemia. METHODS AND RESULTS Twenty-three(More)
BACKGROUND Bone marrow cell injection has been introduced to treat patients with ischemic heart disease. However, focal application of bone marrow cells may generate an arrhythmogenic substrate. OBJECTIVES To assess the electrophysiological and arrhythmogenic effects of intramyocardial bone marrow cell injection in patients with chronic myocardial(More)
