Background Endothelial progenitor cells (EPCs) are responsible for angiogenesis and maintenance of microvascular integrity, the number of EPCs is usually correlated with oxidative stress. When compared with those with preserved circumferential strain, patients with an impaired circumferential strain had a lower number of Compact disc34+ EPCs (2.63??1.80% vs. 3.87??2.10%, P? ?0.01) and SOD level (0.13??0.06U/ml… Continue reading Background Endothelial progenitor cells (EPCs) are responsible for angiogenesis and maintenance
