1. Disparities In The Use Of Drug-eluting Stents For Diabetic Patients With ST-elevation Acute Myocardial Infarction Assisted In the Public versus Private Network - VICTIM Register
Resumo Fundamento: A angioplastia primária (AP) com colocação de stent, seja ele convencional ou farmacológico, representa a principal estratégia no tratamento do infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMCSST). Os pacientes diabéticos, entretanto, representam população especial no IAMCSST, com altas taxas de reestenose

2. Impact of free thyroxine levels and other clinical factors on bare metal stent restenosis
ABSTRACT Objective Thyroid hormones have both direct and indirect effects on thermogenesis such as modulating vascular smooth muscle cell proliferation. However, the influence of more subtle changes in thyroid hormones on coronary atherosclerosis remains a matter of speculation. Smooth muscle cells play a crucial role in the pathogenesis of in-stent resten

3. Alterações histopatológicas de stents metálicos no endotélio coronariano \"in vivo\" / Histopathological abnormality in coronary artery bare stent metal \"in vivo\"
Duas técnicas invasivas para o tratamento da doença aterosclerótica coronariana oclusiva firmaram-se ao longo dos anos: revascularização cirúrgica do miocárdio e angioplastia transcutânea com stents metálicos. O estudo visa comparar as alterações histopatológicas causadas por stents metálicos coronarianos fabricados com a superliga de composiç�

4. Vetorização termoinduzida de nanopartículas magnéticas biocompatíveis: uma aplicação no recobrimento de Stents nus por via líquida / Thermally induced vectorization of Biocompatible Magnetic Nanoparticles: an application to cover Bare Metal Stents by Dip Coating
Neste trabalho foi desenvolvida uma técnica de Dip Coating (deposição por via líquida) que permite controlar o gradiente de temperatura entre o substrato e o material que se quer depositar em sua superfície. Em particular, foi investigado o efeito de adsorção de nanopartículas magnéticas biocompatíveis na superfície de Stents nus em diversas condi

5. Utilização do ultra-som intracoronário com Histologia Virtual® na identificação de lesões propensas à reestenose após o implante de stents / Application of Virtual Histology®-intravascular ultrasound (VH-IVUS) to identify restenosis-prone lesions after baremetal and sirolimus-eluting stents
To the present, little is known about the correlation between modifications in plaque composition at stent edges and the changes in vessel geometry. This study sought to evaluate, by serial grey-scale intravascular ultrasound (IVUS) and Virtual Histology(TM), the modifications in plaque composition at the edges of drug-eluting and bare-metal stents and the c

6. Investigação das modificações na geometria vascular nas bordas de stents farmacológicos e não-farmacológicos e a correlação com a composição dos ateromas: estudo seriado com ultrassom intracoronário e Histologia Virtual® / Investigation of the modifications in vascular geometry at the edges of bare-metal and drug-eluting stents and the correlation of modifications in plaque composition: a serial with grey-scale intravascular ultrasound and Virtual Histology(TM)

7. Avaliação tardia dos stents liberadores de Biolimus A9® pela tomografia de coerência óptica: análise da cobertura tecidual e da aposição das hastes / Long-term follow-up Biolimus A9TM stents with optical coherence tomography: strut apposition and tissue coverage analysis
Introduction: First generation drug-eluting stents (DES) have emerged as a strategy to prevent in-stent restenosis and the need of target-vessel revascularization when compared to bare metal stents (BMS); but at the expense of a higher risk of very late stent thrombosis (ST). Uncovered and malapposed struts may be associated with both late and very late ST.

8. Influence of metal alloy and the profile of coronary stents in patients with multivessel coronary disease
BACKGROUND: In Brazil, despite the recommendations of the Brazilian Society of Hemodynamics and Interventional Cardiology, the National Health System has not yet approved the use of drug-eluting stents. In percutaneous coronary interventions performed in the public and part of the private health care system, bare metal stents are used as the only option. The

9. Effect of oral sirolimus therapy on inflammatory biomarkers following coronary stenting
We studied the effect of oral sirolimus, administered to prevent and treat in-stent restenosis (ISR), on the variation of serum levels of inflammatory markers following coronary stenting with bare metal stents. The mean age of the patients was 56 ± 13 years, 65% were males and all had clinically manifested ischemia. Serum levels of high sensitivity C-reacti

10. Predictors of restenosis after percutaneous coronary intervention using bare-metal stents: a comparison between patients with and without dysglycemia
The objective of this study was to identify intravascular ultrasound (IVUS), angiographic and metabolic parameters related to restenosis in patients with dysglycemia. Seventy consecutive patients (77 lesions) selected according to inclusion and exclusion criteria were evaluated by the oral glucose tolerance test and the determination of insulinemia after a s

11. Analysis of cost-effectiveness of drug eluting versus bare metal stents. Cost, effectiveness and results in medium and long-term. / Análise do custo-efetividade dos stents farmacológicos versus stents convencionais: resultados clínicos e de custos a médio e longo prazo
Os resultados tardios com os stents farmacológicos são melhores do que com stents convencionais, principalmente no que se refere à reestenose. Entretanto, no mundo real, os stents farmacológicos são implantados em pacientes de maior complexidade, o que teoricamente já diminui a diferença dos resultados. Comparar resultados da utilização de stents co

12. A novel method for endoluminal treatment of abdominal aortic aneurysms. With bare-metal Wallstent endoprostheses and endovascular coils.
The established therapy for symptomatic, expanding abdominal aortic aneurysms is open surgical replacement with an artificial graft. Over the last several years, there has been increasing enthusiasm for the use of endoluminal graft prostheses to exclude abdominal aortic aneurysms. However, even with rapid advances in stent graft technology, certain problems
