Abstract

This study was designed to determine the levels of early endothelial progenitor cells (EPCs), apelin, vascular endothelial growth factor (VEGF) and stromal cell-derived growth factor-1 (SDF-1) after acute myocardial infarction (AMI), and to investigate the relationships between these cytokines and early EPCs. Early EPCs, defined as CD133+, KDR+, and CD34+ cells, were quantified by flow cytometry. The levels of early EPCs and those cytokines in AMI patients were significantly different from those with coronary artery disease or controls (P < 0.05). Plasma apelin levels were inversely correlated with Gensini score and early EPCs (both P < 0.01). Early EPCs, VEGF and SDF-1 showed different patterns of changes in AMI patients during the first 24 h. The trend in the change of early EPCs was proportionally correlated with that of VEGF (P < 0.05). AMI patients exhibited increased early EPCs with remarkably decreased apelin levels and enhanced VEGF levels.
