Abstract: The coronary implantation of heart stents is one of the important methods for the treatment of coronary heart disease. With the advances of biomaterial technology, rapid development has been achieved in the application of heart stents materials. The author introduced the evolution of heart stents materials in terms of metal stents, drug-eluting stents and soluble stents, and that the application of novel material stents is the important rout to reduce the rate of cardiovascular restenosis. Additionally, the future of materials of stents was also looked into.

Key words: heart stents, materials, restenosis
