Evaluation of PTCA versus Stenting and Bare-Metal Stenting versus Drug-Eluting Stenting in the Treatment of Coronary Artery Disease

چکیده
Introduction: The risk of developing coronary artery disease (CAD) for both men and women is increasing in society today. Over the past twenty-five years, the concepts of percutaneous transluminal coronary angioplasty (PTCA) and stenting have become dominant modalities in the treatment of CAD. In the late 1970’s and early 1980’s, PTCA was seen as the best possible alternative to bypass surgery until repetitive treatments were required to reopen occluded arteries. Following the failure of PTCA, stenting and derivatives of stenting with drug-eluting compounds have been developed to examine the most effective revascularization technique to reduce the rate of coronary restenosis. Methodology: The purpose of this study was to perform a systematic examination of the literature to evaluate these techniques. Articles used included randomized controlled clinical trials of adults ranging from 50 to 75 years of age who had undergone either PTCA or stenting from the years 1979 to 2006. Key variables evaluated in the study were PTCA, stenting, and drug-eluting stents. Results: Thirty articles met the inclusion criteria and were reviewed using evidence based methods. Following analysis, the overwhelming consensus exists that the use of PTCA with stenting is more effective than angioplasty alone, and drugeluting stenting is more effective than bare-metal stenting in the prevention of re-stenosis in patients with CAD. Conclusion: The most effective treatment for patients with CAD is PTCA with drug-eluting stenting.

Outcomes following coronary stenting in the era of bare-metal vs the era of drug-eluting stents.
CONTEXT Although drug-eluting stents reduce restenosis rates relative to bare-metal stents, concerns have been raised that drug-eluting stents may also be associated with an increased risk of stent thrombosis. Our study focused on the effect of stent type on population-based interventional outcomes. OBJECTIVE To compare outcomes of Medicare beneficiaries who underwent nonemergent coronary ste...

INTRODUCTION we investigated the outcomes of stenting with overlapping drug-eluting stents (DES) versus overlapping stenting with a combination of drug-eluting and bare metal stents (BMS) in very long coronary lesions (≥ 25 mm). METHODS AND RESULTS fifty-two patients treated with either overlapping DES-DES (n = 22) or DES-BMS (n = 30) were selected from a registry of 588 patients with very lo...

Stents versus coronary-artery bypass grafting for left main coronary artery disease.
BACKGROUND Several studies have compared the treatment effects of coronary stenting and coronary-artery bypass grafting (CABG). However, there are limited data regarding the long-term outcomes of these two interventions for patients with unprotected left main coronary artery disease. METHODS We evaluated 1102 patients with unprotected left main coronary artery disease who underwent stent impl...
