Drug-eluting stent and the prevalence of latent thrombus after five years, suggesting patients may continue to be at risk for stent thrombosis for an extended period of time.

Stent occlusion because of thrombosis may occur during the procedure, in the following days, or later. The presence of thrombi around the stent may, in turn, affect the drug-eluting performance of the stent. Treatment with the antiplatelet drugs aspirin and clopidogrel appears to be the most important factor reducing this risk of thrombosis, and early cessation of one
