conclusions regarding the efficacy outcomes of the patients after des implantation, no differences were found between shorter (≤ 6 months) and longer (≥ 12 months) duration of dapt. what is worse is that longer duration (≥ 12 months) was associated with increased risk of bleeding complications. evidence acquisition this study was conducted at the department of cardiology, the first college of c...

Bare metal stents have a proven safety record, but limited long-term efficacy due to in-stent restenosis. First-generation drug-eluting stents successfully countered the restenosis rate, but were hampered by concerns about their long-term safety. Second generation drug-eluting stents have combined the low restenosis rate of the first generation with improved long-term safety. We review the evol...

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 Sirolimus-eluting stents have recently been shown to reduce the risk of restenosis among patients who undergo percutaneous coronary intervention (PCI). Given that sirolimus-eluting stents cost about 4 times as much as conventional stents, and considering the volume of PCI procedures, the decision to use sirolimus-eluting stents has large economic implications. METHODS We performed ...

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 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...

BACKGROUND Drug-eluting stents significantly improved angiographic and clinical outcomes compared with bare metal stents in diabetic patients. However, a comparison of everolimus-eluting stents and sirolimus-eluting stents in diabetic patients has not been evaluated. Therefore we compared effectiveness of everolimus-eluting stents and sirolimus-eluting stents in patients with diabetes mellitus....

BACKGROUND Some (but not all) prior trials have reported differential outcomes after percutaneous coronary intervention with paclitaxel-eluting stents versus stents eluting rapamycin analogs according to the presence of diabetes mellitus. These studies lacked sufficient power to examine individual safety and efficacy end points. METHODS AND RESULTS To determine whether an interaction exists b...

BACKGROUND The aim of this study was to compare the safety and efficacy of biodegradable-polymer (BP) drug-eluting stents (DES), bare metal stents (BMS), and durable-polymer DES in patients undergoing coronary revascularization, we performed a systematic review and network meta-analysis using a Bayesian framework. METHODS AND RESULTS Study stents included BMS, paclitaxel-eluting (PES), siroli...
