This meta-analysis combined the results of randomized clinical trials to compare the efficacy of drug-eluting stents with that of bare metal stents in percutaneous coronary interventions to ascertain which revascularization strategy is most safe and effective. The literature identified 13 published studies, and 8 were included in the main meta-analysis, thus allowing a meta-analysis on 3,860 pa...
The introduction of intracoronary stents represented a major advance in interventional cardiology. While bare metal stents set the benchmark for improved safety over angioplasty, intimal hyperplasia and subsequent restenosis were important limitations. First-generation drug-eluting stents demonstrated significant improvements in efficacy, but not necessarily safety, and further technologic deve...
Coronary artery disease is characterized by a narrowing (stenosis) of the arteries that supply blood to the tissue of the heart. Continued restriction of blood flow manifests itself as angina and ultimately myocardial infarction (heart attack) for the patient. Heart bypass was once the only treatment for this condition, but over the years percutaneous coronary intervention (PCI) has become an i...
Drug-eluting stents implanted in blood vessels are subject to various dynamics of flow. In this study, we present the evaluation a mathematical model considering effect flow rate, simulate kinetic profiles drug release (Diclofenac Sodium (DS)) from in-vitro PLGA films. This solves set non-linear equation for modeling simultaneously burst, diffusion, swelling and erosion involved mechanisms libe...
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...
Two cases of drug-eluting stent restenosis after percutaneous coronary intervention in the left main coronary artery and its bifurcation are presented. An off-pump coronary artery bypass grafting following in-stent restenosis was performed. Drug-eluting stents have shown a reduced frequency of in-stent restenosis and a good safety profile compared with bare metal stents. However, intervention w...
BACKGROUND The safety of drug-eluting stents has been called into question by recent reports of increased stent thrombosis, myocardial infarction, and death. Such studies have been inconclusive because of their insufficient size, the use of historical controls, a limited duration of follow-up, and a lack of access to original source data. METHODS We performed a pooled analysis of data from fo...
INTRODUCTION AND OBJECTIVES The effectiveness of coronary drug-eluting stents has not been fully studied in very elderly patients who have clinical features that predispose them to side effects and long-term adverse events. METHODS The safety and efficacy of drug-eluting stents were studied in a historical cohort of consecutive octogenarian patients who underwent percutaneous coronary interve...
