1. Rapamycin and Paclitaxel Affect Human Aortic Smooth Muscle Cells-Derived Foam Cells Viability and Proliferation
Abstract Introduction: Drug-eluting stents (DES) coated with rapamycin or paclitaxel as antiproliferative substances significantly reduced the incidence of clinical restenosis and had fewer side effects after percutaneous coronary intervention. However, DES coated with rapamycin or paclitaxel still cause restenosis due to abnormal tissue growth which remain

3. 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

4. CABG Surgery Remains the best Option for Patients with Left Main Coronary Disease in Comparison with PCI-DES: Meta-Analysis of Randomized Controlled Trials
Abstract Objective: To compare the safety and efficacy of coronary artery bypass grafting (CABG) with percutaneous coronary intervention (PCI) using drug-eluting stents (DES) in patients with unprotected left main coronary artery (ULMCA) disease. Methods: MEDLINE, EMBASE, CENTRAL/CCTR, SciELO, LILACS, Google Scholar and reference lists of relevant articles

5. Segurança e eficácia dos stents farmacológicos eluidores de biolimus com polímero biodegradável: análise do registro EINSTEIN (Evaluation of Next-generation drug-eluting STEnt IN patients with coronary artery disease)
OBJETIVO: Avaliar a incidência de eventos adversos cardíacos maiores (morte cardíaca, infarto agudo do miocárdio ou necessidade de nova revascularização do vaso-alvo) em 1 ano em pacientes do "mundo real". MÉTODOS: O registro EINSTEIN é um estudo observacional prospectivo, unicêntrico, que incluiu consecutivamente 103 pacientes (152 lesões) tratado

6. 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

8. 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.

9. Evolução tardia de pacientes com infarto agudo do miocárdio tratados com stents farmacológicos na prática diária do mundo real: subanálise do Registro DESIRE (Drug-Eluting Stent In the REal World)
INTRODUÇÃO: Estudos prévios comparando stents farmacológicos (SFs) e stents não-farmacológicos sugerem eficácia e segurança dos SFs no tratamento de pacientes com infarto agudo do miocárdio (IAM). No entanto, a evolução tardia de pacientes com IAM tratados com SFs na prática diária permanece desconhecida. Este estudo teve como objetivo investiga

10. 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
