"The concept of coronary artery balloon angioplasty was introduced by Andreas Gruentzig in 1977 and was the mainstay of percutaneous coronary intervention in the late 1970s and 1980s. Coronary bare-metal stents were developed with the implantation of the first self-expanding stent by Sigwart, Puel and colleagues in 1986 1-3. The balloon-expandable stent was developed afterwards. Consecutive optimisation of implantation techniques and the introduction of dual antiplatelet therapy were made in the 1990s. A high rate of in-stent restenosis of bare metal stents led to the development of drug-eluting stents (DES) in the early 2000s, which were initially associated with similar risks of major adverse cardiovascular events (MACE) with a smaller risk of repeat revascularisation in the first six months after stent placement but a higher risk thereafter 3. This led to recommendations of extending concomitant dual antiplatelet therapy to at least 12 months 4 and the development of newer generations of drug-eluting stents in which the calibre of struts was significantly reduced and more biocompatible and durable coatings have been introduced including ‘polymer free’ coatings 2."
"Coronary stents significantly reduce complications and limitations of pure balloon angioplasty as acute vascular recoil, restenosis and acute coronary occlusion due to dissection in the early postintervention period 1."
"High rates of acute stent thrombosis due to neointimal hyperplasia have been reduced with the use of drug-eluting stents (DES) and delayed arterial healing associated with those could be improved by the reduction of strut size, newer antiproliferative agents, coating or carrier-free technologies 1."
