Early EPCs, de- fined 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 in- creased early EPCs with remarkably decreased apelin levels and enhanced VEGF levels.展开更多
