The future of drug eluting stents

In-stent restenosis (ISR) is the major drawback of percutaneous coronary interventions, occurring in 10–40% of patients. Drug eluting stents (DES) are successful in a large majority of patients in preventing restenosis for the first year after implantation. Recently, new stents have emerged that are loaded with anti-inflammatory, antimigratory, antiproliferative, or pro-healing drugs. These drugs are supposed to inhibit inflammation and neointimal growth and subsequently ISR. The future of DES lies in the development of better stents with new stent designs, better polymers including biological polymers and biological biodissolvable stent coatings, and new, better drugs.
