In the first stage of<unk> , administering anti-platelet drugs (called IIb/IIIa inhibitors) immediately after surgery greatly reduces the chance of a thrombosis occurring. Drug-eluting stents, coated with pharmaceuticals that inhibit tissue growth and thus reduce the risk of<unk>  from scar-tissue and cell proliferation, are now widely used. These stents reduce the occurrence of<unk> , with clinical studies showing an incidence rate of 5% or lower.
