According to the author, from the use of Stent's compound as a support for facial tissues evolved the use of a stent to hold open various bodily structures. The first (self-expanding) "stents" used in medical practice in 1986 by Ulrich Sigwart
Drug-eluting stent of thrombosis was shown after the first year, compared to bare-metal stents. Late stent thrombosis often causes myocardial infarction and sometimes death. In other analyses, the late thrombosis risk is offset by drug-eluting stents' markedly reduced risk of restenosis and its complications including myocardial infarction. A meta-analysis concluded the mortality risk associated with drug-eluting and bare-metal stents is similar. Drug-eluting stents generally consist of three parts - the stent platform, a polymer coating that binds the drug to the stent and releases drug (although stents have been tested that do without a coating), and the drug. The stent platform itself
