CONTEXT Approval of drug-eluting coronary stents was based on results of relatively small trials of selected patients; however, in routine practice, stents are used in a broader spectrum of patients. OBJECTIVE To compare the first 2 commercially available drug-eluting stents-sirolimus-eluting and paclitaxel-eluting-for prevention of symptom-driven clinical end points, using a study design ref...
Stent fracture (SF) has been implicated as a risk factor for in-stent restenosis, but its incidence and clinical characteristics are not well established. Therefore we investigated the conditions associated with stent fracture and its clinical presentation and outcome. Between 2004 and 2007, consecutive cases of SF were collected from the Seoul National University Hospital. Clinical characteris...
BACKGROUND/AIMS To investigate whether temporary placement of a paclitaxel or rapamycin eluting stent is more effective to reduce stenting induced inflammatory reaction and scaring than a bared stent in benign cardia stricture models. MATERIALS AND METHODS Eighty dog models of stricture were randomly divided into a control group (CG, n=20, no stent insertion), a bare stent group (BSG, n=20), ...
A synergistic impact of research in the fields of post-angioplasty restenosis, drug-eluting stents and vascular gene therapy over the past 15 years has shaped the concept of gene-eluting stents. Gene-eluting stents hold promise of overcoming some biological and technical problems inherent to drug-eluting stent technology. As the field of gene-eluting stents matures it becomes evident that all t...
BACKGROUND Recent studies have questioned the safety of drug-eluting stents because of a higher incidence of late stent thrombosis, raising the possibility that drug-eluting stents may be associated with an increased mortality. The effect of drug-eluting stents on mortality in African-Americans is unknown. METHODS We evaluated 628 African-American patients (354 patients treated with drug-elut...
BACKGROUND The safety of drug-eluting stents has been called into question by recent reports of increased stent thrombosis, myocardial infarction, and death. Such studies have been inconclusive because of their insufficient size, the use of historical controls, a limited duration of follow-up, and a lack of access to original source data. METHODS We performed a pooled analysis of data from fo...
BACKGROUND Controversy exists about the impact of treating bifurcations on overall outcome of coronary interventions using drug-eluting stents (DES). We sought to investigate 1-year outcome of the treatment of bifurcation lesions using DES in a large "real-world" cohort. METHODS AND RESULTS Among 5,126 patients enrolled in phase I of the multicenter German Drug-Eluting Stent Registry, 814 (16...
BACKGROUND Diabetes is a powerful predictor of adverse events in patients undergoing percutaneous coronary intervention. Drug-eluting stents reduce restenosis rates compared with bare metal stents; however, controversy remains regarding which drug-eluting stents provides greater benefit in patients with diabetes. Accordingly, we compared the safety and efficacy of sirolimus-eluting stents (SES)...
Background—Diabetes is a powerful predictor of adverse events in patients undergoing percutaneous coronary intervention. Drug-eluting stents reduce restenosis rates compared with bare metal stents; however, controversy remains regarding which drug-eluting stents provides greater benefit in patients with diabetes. Accordingly, we compared the safety and efficacy of sirolimus-eluting stents (SES)...
BACKGROUND Although effective coverage of challenging coronary lesions has warranted the use of overlapping drug-eluting stents, the histopathological response to stent overlap is unknown. METHODS AND RESULTS The arterial reaction to overlapping Cypher or Taxus drug-eluting stents was examined in rabbits with bare metal stents, BxVelocity or Express, serving as controls. Single iliac artery b...
