Original Title: Polymer-free Drug-Coated Coronary Stents in Patients at High Bleeding Risk Reference: Philip Urban et al. N Engl J Med. 2015 Oct 14. [Epub ahead of print]. High bleeding risk patients undergoing PCI usually receive conventional bare metal stents (BMS) to allow the shortest possible DAPT (dual antiplatelet therapy), usually a month long. This...
Fundamentos e objetivos: O uso de stent farmacológico (DES) ao invés de stent “convencional” não farmacológico (BMS) em pacientes com risco de sangramento elevado (HBR) continua controverso devido a necessidade de maior duração da terapia de anti-agregação plaquetária dupla (DAPT), fato que causa preocupação em relação à segurança. O DES eluidor de zotarolimus Endeavor Sprint...
Fundamentos: A duração ideal da terapia antiplaquetária dupla (DAPT) após implante de stent ainda é controversa e gera muita discussão. As diretrizes internacionais sugerem a avaliação da duração da DAPT de acordo com o risco de isquemia e sangramento do paciente. No entanto, ainda não foi proposto um método de quantificação adequada desses riscos. Objetivos:...
Fundamentos: Diversos estudos para avaliação de segurança e eficácia dos stents farmacológicos com polímeros biodegradáveis estão em andamento, sobretudo na vigência de infarto do miocárdio com supra-desnivelamento do segmento ST (STEMIs). Objetivos: Confirmar a segurança e eficácia do stent farmacológico com polímero bioabsorvível Ultimaster em STEMIs. Métodos: Estudo multicêntrico, cego, prospectivo, randomizado (3:1 Ultimaster DES...
Fundamentos: Os stents farmacológicos (DES) diminuem as taxas de reestenose, no entanto, ainda existem preocupações sobre a segurança e eficácia da utilização de balões eluidores de drogas após o implante de stents convencionais, especialmente no infarto do miocárdio com elevação do segmento ST (STEMI). Objetivos: O objetivo deste estudo foi avaliar a segurança e a...
Background: Octogenarian patients represent an increasingly growing population. In addition, this age group has a higher proportion of co-morbidities with more extensive and complex coronary disease. However, they have often been excluded from major studies, whose average age is usually 60 years. Despite having a more complex coronary anatomy, the role of pharmacological stent (DES)...
Drug-eluting balloons could reduce intimal hyperplasia detected by OCT in intmerventions with conventional stents. 30 patients were randomized into 3 groups: 10 patients received conventional stents, 10 patients received a drug-eluting balloon prior to the conventional stent, and 10 patients receive a drug-eluting balloon after the conventional stent. We performed angiographic and OCT follow-up at...
This new stent is a sirolimus-eluting low-profile cobalt chrome platform (80 µm) with a rapid resorption polymer (3 months). Theoretically, it presents less risk of inflammation of the vessel due to the kinetics of drug elution and polymer degradation. The objective of this study was to test the safety and efficacy of the new device....
There is still concern about the safety of drug-eluting stents (DES) due to the possibility of late and very late thrombosis. Dual antiplatelet aggregation for a year is recommended for patients receiving DES. The objective of this study was to test the non-inferiority of a new drug-eluting stent in terms of endothelial coverage after 3...
Original title: Drug-Eluting Stents versus Bare Metal Stents Prior to Noncardiac Surgery. Reference: Sripal Bangalore, et al. Catheterization and Cardiovascular Intervention 2015;85:533-41 Drug eluting stents (DES) have proved beneficial compared to bare metal stents (BMS), but the need to program a surgical procedure after a percutaneous coronary intervention (PCI) has limited its use. This study analyzed patients receiving...
