INTRODUCTION AND OBJECTIVES We performed a pooled analysis based on patient-level data from the TITAX-AMI and BASE-ACS trials to evaluate the outcome of titanium-nitride-oxide-coated bioactive stents vs drug-eluting stents in patients with ST-segment elevation myocardial infarction at 2-year follow-up. METHODS The TITAX-AMI trial compared bioactive stents with paclitaxel-eluting stents in 425...

There is histological evidence that drug-eluting stents are associated with delayed endothelialization and a persistent inflammatory state. Moreover, clusters of inflammatory cells have been observed on luminal surfaces by scanning electron microscopy. With the aim of quantifying this inflammatory response, we implanted one bare-metal stent and two drug-eluting stents containing different doses...

BACKGROUND There is evidence that endothelial coverage of drug-eluting stents might be delayed or absent, a risk factor for late thrombotic events. We studied the effects of different drug-polymer-device iterations on endothelium-dependent coronary vasomotion. Systemic markers of endothelial inflammation were correlated with coronary vasomotor changes. METHODS AND RESULTS Patients with paclit...

Previous research from our group has demonstrated arsenic trioxide eluting stents significantly reduced neointimal area and thickness compared with bare metal stents. In the present study, the anti-inflammatory effects of arsenic trioxide in vitro and arsenic trioxide eluting stents in a porcine coronary model have been explored. Sixty-five pigs underwent placement of 139 oversized stents in th...

OBJECTIVE To compare the effectiveness and safety of three types of stents (sirolimus eluting, paclitaxel eluting, and bare metal) in people with and without diabetes mellitus. DESIGN Collaborative network meta-analysis. DATA SOURCES Electronic databases (Medline, Embase, the Cochrane Central Register of Controlled Trials), relevant websites, reference lists, conference abstracts, reviews, ...

CONTEXT Although drug-eluting stents reduce restenosis rates relative to bare-metal stents, concerns have been raised that drug-eluting stents may also be associated with an increased risk of stent thrombosis. Our study focused on the effect of stent type on population-based interventional outcomes. OBJECTIVE To compare outcomes of Medicare beneficiaries who underwent nonemergent coronary ste...

Two cases of drug-eluting stent restenosis after percutaneous coronary intervention in the left main coronary artery and its bifurcation are presented. An off-pump coronary artery bypass grafting following in-stent restenosis was performed. Drug-eluting stents have shown a reduced frequency of in-stent restenosis and a good safety profile compared with bare metal stents. However, intervention w...

BACKGROUND Previous research suggests that the early benefit from revascularization with drug-eluting stents might diminish over time. METHODS We performed an extended analysis of a previously identified cohort of 6440 patients who underwent percutaneous coronary intervention between April 1, 2003 and March 31, 2005 using a prospective provincial clinical registry in Alberta, Canada. We compa...

BACKGROUND The drug-eluting stents have decreased the incidence of instent restenosis compared to bare metal stents. But, the incidence of late and very late stent thrombosis has increased with the drug-eluting stents. CASE PRESENTATION We are here, reporting three cases of incredibly late instent thrombosis, each one occurring after more than 50 months of drug-eluting stent placement. CONC...

Drug-eluting stents implanted in blood vessels are subject to various dynamics of flow. In this study, we present the evaluation a mathematical model considering effect flow rate, simulate kinetic profiles drug release (Diclofenac Sodium (DS)) from in-vitro PLGA films. This solves set non-linear equation for modeling simultaneously burst, diffusion, swelling and erosion involved mechanisms libe...
