Drug eluting stents (DES) release drugs that inhibit tissue growth in narrowed coronary arteries in an effort to prevent restenosis, a renarrowing of the artery. Several types of DES are under investigation in clinical trials; however, none are currently approved for use in Canada. Preliminary trial data are encouraging, demonstrating greater lumen diameter and reduced restenosis with DES versu...
CONTEXT Compared with bare metal stents, sirolimus-eluting and paclitaxel-eluting stents have been shown to markedly improve angiographic and clinical outcomes after percutaneous coronary revascularization, but their performance in the treatment of de novo coronary lesions has not been compared in a prospective multicenter study. OBJECTIVE To compare the safety and efficacy of sirolimus-eluti...
Background. Individual randomized trials have suggested that everolimus-eluting stents may have improved clinical outcomes compared to paclitaxel-eluting stents, but individual trials are underpowered to examine outcomes such as mortality and very late stent thrombosis. Methods. Medline, Cochrane, and conference proceedings were searched for randomized trials comparing everolimus versus paclita...
Introduction: This study aimed to evaluate the effects of four-time inflation of the stent balloon at nominal pressure on optimal stent expansion in resistant lesions. Materials and Methods: This interventional study was conducted on 39 patients with coronary artery lesions, in whom Zotarolimus-eluting stents (N=20), Paclitaxel-eluting stents (N=11) and other stents (N=8) were deployed four tim...
The root cause of coronary artery disease is atherosclerosis, ie, intraluminal narrowing (stenosis) of the arteries that supply blood to tissues of the heart. The introduction of the drug-eluting stent over the past decade has revolutionized the field of interventional cardiology. It is used extensively in clinical practice for the treatment of coronary artery disease. The first drug-eluting st...
OBJECTIVES We assessed the impact of vessel size on angiographic and long-term clinical outcome after percutaneous coronary intervention (PCI) with sirolimus-eluting stents (SES) and paclitaxel-eluting stents (PES) within a randomized trial (SIRTAX [Sirolimus-Eluting Stent Compared With Paclitaxel-Eluting Stent for Coronary Revascularization]). BACKGROUND Percutaneous coronary intervention in...
INTRODUCTION Primary percutaneous coronary intervention (PPCI) has become the treatment of choice in patients with ST-segment elevation myocardial infarction (STEMI). Drug-eluting stents (DES) reduce restenosis compared to bare-metal stents (BMS) but there is conflicting data concerning their use in the setting of STEMI. We aimed to evaluate the influence of the type of stent on the outcomes of...
OBJECTIVE The risk of in-stent restenosis can be considerably reduced by stents eluting cytostatic compounds. We created a novel drug-eluting stent system that includes several new features in the rapidly evolving field of stent-based drug delivery. METHODS AND RESULTS The aim of the present study was the preclinical evaluation of a stent-coating system permitting individual, on-site coating ...
The relationship between diabetes mellitus and coronary artery disease is well established. The percentage of patients participating in clinical trials of percutaneous coronary intervention who have diabetes is quickly rising. Diabetic patients have a worse prognosis than nondiabetic patients, with generally greater rates of death, myocardial infarction and need for target lesion and vessel rev...
In their recent systematic review, Suzanne Ligthart and associates compared analyses of the cost-effectiveness of drug-eluting stents. They found that in most studies in which an incremental cost-effectiveness ratio greater than $50 000 per quality-adjusted life-year was calculated the study authors recommended against the widespread use of drug-eluting stents. However, we believe that previous...
