PURPOSE Drug-eluting stents are commonly used for percutaneous coronary intervention. Despite excellent clinical efficacy, the association between drug-eluting stents and the risk for late thrombosis remains imprecisely defined. METHODS We performed a meta-analysis on 14 contemporary clinical trials that randomized 6675 patients to drug-eluting stents (paclitaxel or sirolimus) compared with b...
Editorial Percutaneous coronary intervention (PCI) with implantation of drug‑eluting stents (DESs) has become the standard of care for coronary artery disease and gives a great impetus to device industry. In 2013, approximately half million patients with coronary artery disease underwent PCI in China, with a penetration rate of DES reaching beyond 95%. The use of DES including domestic ones is ...
Although safety profiles of sirolimus-eluting stents do not seem to differ in short-to-medium term from those of bare-metal stents, late stent thrombosis after deployment of drug-eluting stents has emerged as a potential safety concern in the era of high-pressure stent implantation. Here, we describe the case of a patient with acute myocardial infarction due to stent thrombosis of a sirolimus-e...
BACKGROUND In-stent-restenosis (ISR) is considered to be an essential limiting factor of stenting in coronary heart disease (CHD). The development of coated stents has raised expectations on substantial lowering restenosis after stenting with decreasing the rate of restenosis and a reduction in the rate of clinical events. OBJECTIVES The present analysis addresses the questions on medical eff...
The article published in this edition of the Journal, ‘‘Outcomes of drug-eluting stents compared to bare-metal stents in ST-segment elevation acute myocardial infarction’’ by Brito et al., is based on a registry of primary angioplasty between 2003 and 2007 in a high-volume Portuguese center. The aim of the study was to compare the clinical outcomes of patients presenting with ST-segment elevati...
INTRODUCTION AND OBJECTIVES Rapamycin- and taxol-eluting stents have been shown to reduce restenosis, but there are no large-scale studies of their usefulness in lesions with a high risk of restenosis, or of the relative merits of the two devices. This prospective study compared their safety and efficacy in lesions with a high risk of restenosis. PATIENTS AND METHOD We included consecutive pa...
BACKGROUND The use of sirolimus-eluting coronary stents has been associated with a nearly complete elimination of restenosis at 6 months and with a very low 1-year incidence of major adverse cardiac events (MACE). This analysis examined whether these beneficial effects persist over the longer term. METHODS AND RESULTS This multicenter trial randomly assigned 238 patients to revascularization ...
RE, Popma JJ, Schaff HV, Williams DO, Gibbons RJ, Alpert JP, Eagle KA, Faxon DP, Fuster V, Gardner TJ, Gregoratos G, Russell RO. ACC/AHA guidelines of percutaneous coronary interventions (revision of the 1993 PTCA guidelines)—executive summary. A report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines (committee to revise the 1993 guidelines for...
INTRODUCTION AND OBJECTIVES The use of second-generation drug-eluting stents compared with bare-metal stents in patients with ST-segment elevation myocardial infarction reduces the rate of major adverse cardiac events. We aimed to evaluate the impact of sex on the performance of everolimus-eluting stents vs bare-metal stents in ST-segment elevation myocardial infarction at 2-year follow-up. M...
BACKGROUND The "very late" clinical outcomes for durable polymer drug-eluting stents and bare metal stents (BMSs) have been shown to be dissimilar in clinical studies. Conceptually, the long-term vascular compatibility of BMSs is still regarded to be superior to drug-eluting stents; however, no pathologic study to date has specifically addressed this issue. We evaluated the very late (≥1 year) ...
