Drug-eluting stents. A review of the current literature

Coronary interventions have revolutionized the treatment of coronary artery disease (CAD). Stents, which were used initially for the complications arising from coronary angiography gradually, came to occupy a more prominent role in coronary interventions. However, restenosis remained a limiting factor from a therapeutic point of view. Recent development of drug-eluting stents is a step toward overcoming this problem. This development has elicited a great interest in both physician as well as patient communities. We have reviewed the available medical evidence regarding drug-eluting stents.
