INTRODUCTION AND OBJECTIVES Drug-eluting stents are useful for preventing restenosis, but the patho-physiological processes involved in the proliferative response after implantation are still not known in detail. The aim of this study is to compare the coronary vascular histomorphometry after implanting drug-eluting stents and bare metal stents in a swine model. METHODS Sixty stents were rand...
BACKGROUND AND AIMS Transjugular intrahepatic portosystemic shunts (TIPS) are used in patients with cirrhosis for the prevention of variceal rebleeding. METHODS We retrospectively evaluated re-bleeding rate, patency, mortality, and transplant-free survival (TFS) in cirrhotic patients receiving TIPS implantation for variceal bleeding between 1994-2014. RESULTS 286 patients received TIPS (n =...
Drug-eluting stents reduce the occurrence of in-stent restenosis and the need for subsequent target vessel revascularization compared with bare-metal stents. However, the safety of drug-eluting stents has been called into question because of an apparent increase in late stent thrombosis, a frequently fatal event. A substantial body of research has focused on determining the magnitude of these c...
OBJECTIVES To examine the safety and effectiveness of cobalt-chromium everolimus eluting stents compared with bare metal stents. DESIGN Individual patient data meta-analysis of randomised controlled trials. Cox proportional regression models stratified by trial, containing random effects, were used to assess the impact of stent type on outcomes. Hazard ratios with 95% confidence interval for ...
Background: Small side branches, albeit less important than their larger counterparts, have not yet received due attention in the literature. Nor has there ever been a comparison between drug-eluting stents and bare metal stents apropos side branch occlusion. The aim of this study was to compare the patency of small (≥0.5 and ≤1.5 mm in diameter) side branches with respect to bare metal vs. dru...
BACKGROUND Although randomized studies have shown a beneficial effect of drug-eluting stents in reducing the risk of repeated revascularization, these trials were underpowered to compare rates of death and myocardial infarction. The long-term safety of drug-eluting stents has been questioned recently. METHODS We performed a pooled analysis of 1748 patients in four randomized trials evaluating...
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...
Patients with diabetes mellitus have less favourable outcomes after percutaneous coronary intervention (PCI) than non-diabetics. We performed a subgroup analysis of the multicentre RAVEL trial to examine the impact of the sirolimus-eluting stent (SES) on outcomes in diabetic patients. The RAVEL study randomized 238 patients to treatment with either sirolimus-eluting or bare metal stents. Forty-...
CONTEXT AND OBJECTIVE The safety and efficacy of drug-eluting stents reduce the need for surgical revascularization. The objective of the present study was to investigate whether paclitaxel or rapamycin-eluting stent are effective in avoiding the need for coronary-artery bypass grafting. METHODS This was a systematic review of the literature using the methodology of the Cochrane Collaboration...
