Comparing long-term antiplatelet strategies to prevent morbidity and mortality in patients with drug-eluting coronary stents
… unknown in patients greater than one year after drug-eluting stent (DES) placement. Methods: We modeled life expectancy (LE) using published data by building a Markov model to compare several APT strategies composed of aspirin and clopidogrel, both as monotherapy and in various clinically …

Computational model of local intravascular drug delivery
Drug-eluting stents (DES) virtually eradicate the clinical phenomena of vessel restenosis; yet, they also increase the short and long term risks for stent thrombosis. To improve their safety and efficacy, it is critical to examine factors that alter local biologic outcome. The central hypothesis of …

Clinical outcome and Predictive factors of Coronary aneurysm after Percutaneous Coronary Intervention
… the adjacent reference vessel) at the site of stent implantation are rare and the reported incidence varies from 0.3% to 6%(Aoki et al., 2008). A new term, peri-stent contrast staining (PSS) was defined as contrast staining outside the stent contour extending to ≥20% of the stent diameter which …

Modeling and simulation of coronary stents: Intravascular drug delivery and arterial drug distribution
In-stent restenosis still occurs in coronary arteries implanted with drug-eluting stents, with the maximum thickness observed at the vascular site of maximum inter-strut angle. This phenomenon may be related to the specific spatiotemporal drug uptake in the arterial wall. In this work local …

A system for impedance characterization of coronary stents
Stents are used to re-open and maintain flow in diseased coronary arteries in patients suffering from coronary heart disease. Drug-eluting stents are now the preferred choice of stent but their performance is still limited by delayed healing of the important endothelial cell layer that lines the …

Bleeding Risk Following Percutaneous Intervention in Patients with Diabetes Prescribed Dual Anti Platelet Therapy
… with diabetes (DM) experience higher rates of in-stent restenosis and therefore greater benefit from drug eluting stent (DES) implant at the time of percutaneous coronary intervention (PCI). DES stent implantation necessitates prolonged dual anti-platelet therapy (DAPT). While DAPT reduces the …

Beta-blocker therapy in the era of primary percutaneous intervention for ST elevation myocardial infarction
… statin use, hypertension, obesity, use of drug eluting stent and left anterior descending artery infarct. Cumulative incidence of all-cause death was 10.0% (60 patients) in beta-blocker group during mean follow up months of 56±28 and 25.4% (77 patients) in non beta-blocker group during mean …

The study of a drug coating applied using a cold atmospheric plasma: everolimus coating properties
… and preventing restenosis in cardiovascular stents. Traditional coating methods like dipping and spraying require lengthy drying and curing steps, which may expose the API to heat and poses a risk of degradation. Cold atmospheric plasma (CAP) systems, which operate at low temperatures, offer …
