Abstract
Until recently, in-stent restenosis remained the “Achilles Heal” for interventional cardiologists. The introduction of drug-eluting stents (DES) [CYPHER, Cordis J&J, NJ (sirolimus) and TAXUS, Boston Scientific Corp. Boston (paclitaxel)] however, has made a tremendous impact on rates of in-stent restenosis with dramatic reductions fro 30 to 40% in bare metal stent to 0 to 9% with DES ((1)–(4)).The compelling results from large clinical trial with DES stents involve mostly simple lesion morphologies with follow-up of only 6–12 mo; it is still unclear whether a sustained benefit will be reached in more complex lesions and high-risk patients such as diabetics (5). In this review, the stages of healing in response to bare metal stents implants in animals and humans will be discussed as a bases for understanding the localized effects of polymers and/or drugs on these natural biological processes.
