经皮腔内冠状动脉成形术(percutaneous translu-minal coronary angioplasty,PTCA)是近年来治疗冠状动脉狭窄的理想手段,但较高的术后再狭窄(rest-nosis,RS)发生率严重影响了其远期疗效。血管内皮细胞的损伤、平滑肌细胞的增殖和血管内膜的过度增生是PTCA后再狭窄形成的重要环?
Percutaneous transluminal coronary angioplasty (PTCA) is an ideal method for the treatment of coronary artery stenosis in recent years. However, the high incidence of post-natal restenosis (RS) Long-term efficacy. Vascular endothelial cell injury, smooth muscle cell proliferation and vascular intimal hyperplasia is an important ring of restenosis after PTCA?
