Abstract: Coronary artery disease (CAD) is currently a leading cause of death worldwide. Drug-eluting stents (DESs) have been
dominant for the treatment of CAD in the interventional cardiology world owing to their efficacy in significantly reducing restenosis.
However, late stage stent thrombosis has become a major concern. Stent platform, drug delivery vehicle and type of drug are three
parts of DES and each part affects the performance of the DES. Aiming to provide a clue for the design of future DES, this review
focuses on the development of the three major components of DES and their roles in restenosis and thrombosis. (IJCEM1005004).

Key words: Drug-eluting stents, restenosis, thrombosis
