Drug-eluting coronary stents – focus on improved patient outcomes

Zehra Jaffery, Amit Prasad, John H Lee, Christopher J WhiteDepartment of Cardiovascular Diseases, The John Ochsner Heart and Vascular Institute, Ochsner Clinic Foundation, New Orleans, LA, USAAbstract: The development of stent has been a major advance in the treatment of obstructive coronary artery disease since the introduction of balloon angioplasty. Subsequently, neointimal hyperplasia within the stent leading to in-stent restenosis emerged as a major obstacle in long-term success of percutaneous coronary intervention. Recent introduction of drug-eluting stents is a major breakthrough to tackle this problem. This review article summarizes stent technology, reviews progress of drug-eluting stents and discusses quality of life, patient satisfaction, and acceptability of percutaneous coronary intervention.Keywords: drug-eluting stent, coronary intervention, patient outcomes
