Drug-eluting stent (DES) use has increased greatly as a result of early trial evidence of a reduction in restenosis. However, thet are expensive and do not improve patient survival. Therefore their use has been rationed in some countries. There is a paucity of clinical evidence for some patient groups such as non-ST elevation myocardial infarction and multi-vessel disease. Recent studies suggest that the early benefits of Drug-eluting stents may be offset by an increased risk in late stent thrombosis which is a potentially fatal complication. However, the absolute risk appears low and, as yet, there is no evidence of an increased risk of stent-thrombosis related myocardial infarction or death in patients studied in randomised clinical trials. Long-term use of anti-platelet therapy may protect against the risk of late stent thrombosis but the optimal treatment strategy is currently unclear. The aim of this paper is to provide an up-to-date review of the current evidence on DES; including clinical effectiveness, the limitations of existing trials, the emerging evidence on late stent thrombosis and the potential role of clopidogrel.
