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...

BackgroundTreatment of right coronary artery (RCA) aorto-ostial (AO) lesions with bare-metal stents and first-generation drug-eluting (DES) was associated worse outcomes. This study aimed to assess the effect RCA-AO stenting current-generation DES on clinical outcome.MethodsThe large all-comer, multicontinental e-ULTIMASTER registry included 37,198 patients whom 4775 underwent ostial proximal R...

Determining the main dimensions of small vessels while designing is an important and difficult task due to large number mutually exclusive factors affecting hydrodynamic characteristics such vessels. The existing patterns for determining length, width draft are quite general. This complicates their usage vessel a specific design. In this case, it necessary check technical solutions, one ways th...

background and objective: cerebral arteriovenous malformation (cavm) hemodynamic is disease condition, results changes in the flow and pressure level in cerebral blood vessels. measuring flow and pressure without catheter intervention along the vessel is big challenge due to vessel bifurcations/complex bifurcations in arteriovenous malformation patients. the vessel geometry in cavm patients are...

background and objective: the circle of willis (cow) supports adequate blood supply to the brain. the cardiovascular system, in the current study, is modeled using an equivalent electronic system focusing on the cow. method: in our previous study we used 42 compartments to model whole car- diovascular system. in the current study, nevertheless, we extended our model by using 63 compartments to ...

Objective(s): Cardiovascular diseases (CVDs) are the leading cause of mortality in the elderly. A common medical procedure for the treatment of CVDs is the replacement of the blocked or narrowed arteries, which is currently the optimal vascular transplant associated with autograft transplantation. In general, the saphenous veins and radial arteries in the mammary gland are considered to be the ...

BACKGROUND Bioresorbable vascular scaffolds were developed to overcome the shortcomings of drug-eluting stents in percutaneous coronary intervention (PCI). We performed an investigator-initiated, randomized trial to compare an everolimus-eluting bioresorbable scaffold with an everolimus-eluting metallic stent in the context of routine clinical practice. METHODS We randomly assigned 1845 patie...

BACKGROUND Recent data have suggested that patients with coronary disease in large arteries are at increased risk for late cardiac events after percutaneous intervention with first-generation drug-eluting stents, as compared with bare-metal stents. We sought to confirm this observation and to assess whether this increase in risk was also seen with second-generation drug-eluting stents. METHOD...

Background—The safety and efficacy of the slow-release, polymer-based, paclitaxel-eluting stent after implantation in a broad cross section of de novo coronary lesions at 1 year are unknown. Methods and Results—In the TAXUS-IV trial, 1314 patients with single de novo coronary lesions 10 to 28 mm in length, with reference-vessel diameter 2.5 to 3.75 mm, coverable by a single study stent, were pr...

More and more clean energy is used worldwide offshore wind power an important part of energy. The difficulty construction problem. integrated floating transport technique composite bucket foundation (CBF) provides method to solve this main purpose paper study verify the safety foundation. Through test method, we determine location distribution where contact force changes greatly identify factor...
