The dynamic change of circulating endothelial progenitor cells counts after percutaneous coronary intervention in patients with chronic stable angina pectoris and its influence factors
Aim To investigate the dynamic changes of circulating endothelial progenitor cells( EPC) counts after percutaneous coronary intervention( PCI) in patients with chronic stable angina pectoris and related factors of CD34~+/KDR~+maximum motivation. Methods 93 patients were divided into PCI group( n = 72) and control group( n = 21).Blood samples were collected by femoral artery sheath or median cubital vein. EPC counts were measured following CAG( baseline) and 1 h,3 h,5 h,7 h,24 h after PCI or CAG by flow cyto...
