مشکلات قلبی عروقی امروزه مشکلات زیادی را برای افرادی زیادی ایجاد کرده است. یکی از عواملی که باعث سکته قلبی می- شود گرفتگی رگ قلب می باشد که به وسیله ی ضایعاتی مانند چربی به وجود می آید. یکی از راه های مقابله با این مشکل استفاده ازاستنت ها قلبی می باشد.حال این استنت ها به دو صورتbare-metal stent وdrug-eluting stent عرضه می-شود.طریقه عملکرد این استنت ها به این صورت می باشد که وقتی در داخل رگ قرار...
Background: Cardiovascular diseases alone have become the leading cause of death worldwide. One of the treatment methods cardiovascular disease is angioplasty. This study aimed to investigate the clinical results after coronary artery angioplasty, based on the incidence of major cardiovascular events with emphasis on stent types. Methods: In this retrospective cross-sectional study, the preval...
the invention of the drug-eluting stent (des) has brought about revolutionary changes in the field of interventional cardiology. in the des era, in-stent restenosis has declined but new issues such as stent thrombosis have emerged. one of the emerging paradigms in the des era is stent fracture. there are reports about stent fracture leading to in-stent restenosis or stent thrombosis. most of th...
Stent thrombosis as a complication of percutaneous coronary intervention frequently is associated with deadly events such as myocardial infarction and sudden death. Definitions of stent thrombosis have not been in a uniform manner in different clinical studies. Two episodes of acute ST elevation myocardial infarction nearly two years after implanting a drug – eluting stent in a 58-year-...
ترومبوز stent به عنوان یک عارضه آنژیوپلاستی عروق کرونر اغلب با حوادث کشنده ای مانند انفارکتوس قلبی و مرگ ناگهانی همراه است. تعاریف ترومبوز stent در مطالعات بالینی مختلف همسان نبوده است. در بیماری که معرفی می شود 2 حمله انفارکتوس قلبی همراه با بالا رفتن قطعه (stemi) st elevation myocardial infarction stتقریبا 2 سال بعد از گذاشتن یک stent دارویی (des) drug eluting stent رخ داده است و وجود ترومبوز...
INTRODUCTION AND OBJECTIVES Initial preclinical studies are required during the process of improving polymers, platforms, and drug-eluting systems for new coronary stent designs. Our objective was to analyze the efficacy and safety of new drug-eluting stent models compared with a conventional stent and commercialized drug-eluting stents in an experimental model with healthy porcine coronary art...
Stent fracture is an uncommon complication of drug-eluting stent implantation, but it has a clinical significance because of its potential association with adverse cardiac events such as in-stent restenosis, target lesion revascularization, and stent thrombosis. Multiple stent fractures account for a small proportion, but they may lead to more serious complications. Newer generation drug-elutin...
BACKGROUND The use of a drug-eluting balloon for the treatment of de novo coronary artery lesions remains to be evaluated. A previous trial in patients with stable and unstable angina comparing a bare metal stent mounted on a drug-eluting balloon with a sirolimus-eluting stent failed to meet the prespecified non-inferiority criteria versus the sirolimus-eluting stent. The stent struts of a bare...
BACKGROUND In-stent restenosis (ISR) remains a difficult problem in interventional cardiology. The relative efficacy and safety of available interventions is not clear. We aimed to perform a network meta-analysis using both direct evidence and indirect evidence to compare all available interventions. METHODS AND RESULTS We systematically searched electronic databases for randomized trials com...
OBJECTIVES To evaluate the efficacy and safety of currently used drug eluting stents compared with each other and compared with bare metal stents in patients with diabetes. DESIGN Mixed treatment comparison meta-analysis. DATA SOURCES AND STUDY SELECTION PubMed, Embase, and CENTRAL were searched for randomised clinical trials, until April 2012, of four durable polymer drug eluting stents (s...
