IMPORTANCE The modest effects of clinical studies using intracoronary administration of autologous bone marrow-derived mononuclear cells (BMCs) in patients with chronic postinfarction heart failure may be attributed to impaired homing of BMCs to the target area. Extracorporeal shock wave treatment has been experimentally shown to increase homing factors in(More)
OBJECTIVES The aim of this study was to identify an association between the quality and functional activity of bone marrow-derived progenitor cells (BMCs) used for cardiovascular regenerative therapies and contractile recovery in patients with acute myocardial infarction included in the placebo-controlled REPAIR-AMI (Reinfusion of Enriched Progenitor cells(More)
BACKGROUND The Fédération Internationale de Football Association (FIFA) World Cup, held in Germany from June 9 to July 9, 2006, provided an opportunity to examine the relation between emotional stress and the incidence of cardiovascular events. METHODS Cardiovascular events occurring in patients in the greater Munich area were prospectively assessed by(More)
BACKGROUND In the REPAIR-AMI trial, intracoronary infusion of bone marrow-derived cells (BMCs) was associated with a significantly greater recovery of contractile function in patients with acute myocardial infarction (AMI) at 4-month follow-up than placebo infusion. The current analysis investigates clinical outcome and predictors of event-free survival at(More)
AIMS Ageing of the immune system, immunosenescence, is characterized by impaired lymphopoiesis, especially B-lymphocyte maturation, and is a hallmark of chronic heart failure (CHF). MicroRNAs (miRNAs) are non-coding, small RNAs, which post-transcriptionally control gene expression of multiple target genes. The miR-181 family is known to control(More)
BACKGROUND Measuring circulating cardiac troponin using novel sensitive assays has revealed that even minute elevations are associated with increased mortality in patients with coronary artery disease or even in the general population. Less well defined, however, is the incremental value of measuring circulating cardiac troponin I (cTnI) by a sensitive(More)
Observations have been made linking the presence of psychosocial factors associated with elevated beta-endorphin concentrations with atherosclerosis. In this study, the authors assume an important role of the stress hormone beta-endorphin in several mechanisms that contribute to a dysbalance of human endothelial and monocytic endothelin (ET)-1 and nitric(More)
OBJECTIVES We sought to assess whether emotional stress-induced acute coronary syndrome (ACS) is mediated by increased inflammatory and vasoconstrictive mediators. BACKGROUND The World Cup soccer 2006 has been shown to provoke levels of stress sufficient to increase the incidence of ACS. However, the mechanisms by which stress translates into vascular(More)
