[Surface Modification and Applications of Cardiovascular Stent].

Cardiovascular disease is one of the most common causes of death.Coronary artery stent implantation has been the most important method to cure coronary disease and inhibit angiostegnosis.However,restenosis and thrombus at the site of implanting cardiovascular devices remains a significant problem in the practice of interventional cardiology.Recently,lots of studies have revealed that endothelial impairment is considered as one of the most important mechanisms contributing to restenosis.As a result,the method of accelerating endothelial regeneration at the injury site could prevent restenosis and thrombus.Considering the surface modification of cardiovascular stent implantation,this paper summarizes the progress on this direction,especially for the prevention of cardiovascular restenosis.Furthermore,this paper also proposes the methods and the future developing prospects for accelerating in vivo re-endothelialization at the site of intravascular stent with different biological molecules.
