We compared the efficacy and safety of drug-eluting stents with that of bare-metal stents in patients who experienced acute ST-segment-elevation myocardial infarction (STEMI) and underwent primary percutaneous coronary intervention. To do this, we performed a meta-analysis of 13 randomized controlled trials in which drug-eluting stents were compared with bare-metal stents in STEMI patients. The...

BACKGROUND Numerous studies have compared the outcomes of coronary artery bypass grafting (CABG) surgery and coronary stenting for the treatment of multivessel coronary disease. In 2003, drug-eluting stents were introduced with the hope of reducing restenosis. However, limited information exists on the comparison of drug-eluting stents and CABG surgery. The long-term outcome of drug-eluting ste...

Drug-eluting stents reduce the occurrence of in-stent restenosis and the need for subsequent target vessel revascularization compared with bare-metal stents. However, the safety of drug-eluting stents has been called into question because of an apparent increase in late stent thrombosis, a frequently fatal event. A substantial body of research has focused on determining the magnitude of these c...

Coronary artery stents revolutionized the practice of interventional cardiology after they were first introduced in the mid-1980s. Since then, there have been significant developments in their design, the most notable of which has been the introduction of drug-eluting stents. This paper reviews the benefits, risks, and current status of Food and Drug Administration-approved drug-eluting stents.

OBJECTIVES/HYPOTHESIS Currently available silicone and metallic stents for tracheal stenosis are associated with problems of granulations, mucus trapping, and difficult removals. Our aim was to develop a novel bioabsorbable tracheal stent with mitomycin C (MMC) drug elution to circumvent such problems. STUDY DESIGN A randomized animal study. METHODS Twenty-five rabbits were randomly assigne...

The undisputed superiority of stents over conventional balloon angioplasty has resulted in a plethora of stents in clinical use. Recent data, however, have indicated not all stent models are the same. Nuances in stent design and construction have impacted significantly on the immediate and long-term clinical outcome. Among the stainless steel stents, those with multicellular or tubular designs ...

Heart disease is a common medical condition that affects hundreds of thousands of people each year in the United States alone. In response, scientists have spent decades researching technologies to treat this disease. Coronary stents are a technology developed to keep collapsing heart vessels open to promote proper blood flow and prevent further cardiovascular complications. Since the 1970s, th...

First generation drug-eluting stents have considerably reduced in-stent restenosis and broadened the applications of percutaneous coronary interventions for the treatment of coronary artery disease. The polymer is an integral part of drug-eluting stents in that, it controls the release of an antiproliferative drug. The main safety concern of first generation drug-eluting stents with permanent p...

BACKGROUND The long-term safety and efficacy of drug-eluting coronary stents have been questioned. METHODS We evaluated 47,967 patients in Sweden who received a coronary stent and were entered into the Swedish Coronary Angiography and Angioplasty Registry between 2003 and 2006 and for whom complete follow-up data were available for 1 to 5 years (mean, 2.7). In the primary analysis, we compare...
