The introduction of drug-eluting stents (DES) in the practice of percutaneous coronary intervention (PCI) has substantially reduced angiographic and clinical restenosis but is associated with an increasing propensity for very late stent thrombosis (ST). Among several clinical, lesion, or procedure-related predictors of ST, early discontinuation of dual antiplatelet therapy (DAPT) is the most important factor for DES-associated late thrombosis; therefore, the optimal duration of DAPT is a major issue to be critically considered in the current DES era...

BACKGROUND: To determine if obstructive sleep apnea (OSA) is a risk factor for early stent thrombosis (EST; within 30 days) after percutaneous coronary intervention (PCI). METHODS: This case-control study involved 23 patients with angiographically confirmed EST after PCI (case group) and 92 PCI patients (control group) who did not develop stent thrombosis during a 2-year follow-up. Patients with symptoms and characteristics consistent with OSA (hereinafter referred to as OSA) were identified using the Berlin questionnaire, and the general characteristics of the patients and their treatments as well as outcomes were recorded...

Platelets play a fundamental role in normal hemostasis, while their inherited or acquired dysfunctions are involved in a variety of bleeding disorders or thrombotic events. Several laboratory methodologies or point-of-care testing methods are currently available for clinical and experimental settings. These methods describe different aspects of platelet function based on platelet aggregation, platelet adhesion, the viscoelastic properties during clot formation, the evaluation of thromboxane metabolism or certain flow cytometry techniques...

Percutaneous coronary intervention (PCI) has become a standard treatment in patients with acute coronary syndrome. However, it is associated with endothelial cell denudation, which may predispose to in-stent thrombosis and restenosis. Pharmacological methods which prevent restenosis can delay post-PCI re-endothelialisation. We have therefore examined how atorvastatin (HMG-CoA reductase inhibitor), sirolimus and everolimus (mTOR inhibitors) affect young and old endothelial cell functions which are responsible for wound healing after PCI...

Coronary artery disease (CAD) is the most common cardiovascular disease while atrial fibrillation (AF) is the most common cardiac arrhythmia. Both diseases share associated risk factors - hypertension, diabetes mellitus, sleep apnea, obesity and smoking. Moreover, inflammation plays a causative role in both diseases. The prevalence of CAD in patients with AF is from 17% to 46.5% while the prevalence of AF among patients with CAD is low and it is estimated from 0.2% to 5%. AF is a well-established factor of poor short- and long-term prognosis in patients with acute myocardial infarction (AMI) and is associated with a marked increase in overall mortality...

OBJECTIVE/BACKGROUND: The objective was to evaluate the feasibility and mid-term outcomes of endoconduits (EC) with the "pave and crack" technique during endovascular aneurysm repair (EVAR) of varying complexity. METHODS: This was a retrospective study. All patients undergoing EC between July 2009 and October 2015 were included. The primary endpoint was technical success of the EC defined as the ability to successfully deliver the aortic stent graft through the EC without rupture, dissection, or thrombosis of the iliac or femoral arteries, and with the absence of haemodynamically significant blood loss related to the EC...

BACKGROUND: Increasing coronary lesion calcification is thought to be associated with adverse percutaneous coronary intervention (PCI) and clinical outcomes. We investigated the effects of calcium burden on culprit lesion morphology and clinical events after intravascular ultrasound (IVUS)-guided PCI in the ADAPT-DES study. METHODS: ADAPT-DES was a prospective, multicenter registry of 8582 consecutive patients undergoing successful PCI using DES. A pre-specified virtual histology (VH)-IVUS substudy of 638 culprit lesions (638 patients) had both pre- and post-PCI VH-IVUS...

Contemporary medical therapy consists of identification and treatment of all patient-modifiable vascular risk factors. Specific atherosclerotic disease therapies are designed to reduce the risk of thrombosis, and the disease progression in order to reduce the risk of future cardiovascular events. Contemporary medical management emphasizes the need to support the patient in achieving lifestyle modifications and to adjust medication to achieve individualized target values for specific quantifiable risk factors...

Right lower extremity edema can be a presenting symptom of iliocaval compression syndrome, even in the absence of deep vein thrombosis. It has been reported in idiopathic and rarely, iatrogenic, cases secondary to variant anatomy, arterial stents, and bony hardware. Classically seen in the more confined left common iliac vein as May-Thurner syndrome, it is rare on the right side. We report an unusual case of acute right common iliac vein compression after right iliac stent placement leading to symptomatic right leg edema...

OBJECTIVE: Patients with May-Thurner syndrome (MTS) present with a spectrum of findings ranging from mild left leg edema to extensive iliofemoral deep venous thrombosis (DVT). Whereas asymptomatic left common iliac vein (LCIV) compression can be seen in a high proportion of normal individuals on axial imaging, the percentage of these persons with symptomatic compression is small, and debate exists about the optimal clinical and diagnostic criteria to treat these lesions in patients with symptomatic venous disease...

The relative long-term efficacy and safety of sirolimus-eluting stents (SES) compared with paclitaxel-eluting stents (PES) in multiple comparative studies remains controversial. This report evaluates 29 randomized trials with 18,379 patients in whom long-term (more than 1 year) outcomes were evaluated. The primary outcomes were target lesion revascularization (TLR) and the secondary end points were death, cardiac death, myocardial infarction (MI), major adverse cardiac events (MACEs), target vessel revascularization (TVR) and stent thrombosis (ST)...

Surface biomimetic modification with extra-cellular matrix (ECM)-derived biomolecules is an emerging potential method of accelerating the healing of vascular stent lesions. However, insufficient capacity of the constructed biofunctional layer in maintaining its long-term efficiency and preventing thrombus and neointimal hyperplasia continue to be major limitations in clinical application. Based on the structure and function of ECM, in this study, we constructed a novel stromal cell-derived factor-1α (SDF-1α)/laminin-loaded nanocoating on the 316L stainless steel (SS) surface to provide improved function in modulation of vascular remodeling...

PURPOSE: To describe an innovative endovascular technique that successfully reconstructs a renal artery completely perfused by the false lumen after thoracic endovascular aortic repair (TEVAR). CASE REPORT: A 65-year-old patient diagnosed with acute Stanford type B aortic dissection underwent successful TEVAR 4 years ago. Regular follow-up found that the thoracic aorta was well repaired, but the false lumen in the abdominal aorta had enlarged year by year. The left renal artery was supplied entirely by the false lumen, which caused kidney hypoperfusion...

BACKGROUND: Although drug-eluting stents have dramatically reduced the rates of restenosis and target lesion revascularization, they are associated with stent thrombosis (ST), a catastrophic event likely due to delayed endothelialization and chronic inflammation caused by the polymer and the metal scaffolds. To increase the safety and efficacy of stents, polymer-free dual drug-eluting stents (DDES) have been developed. METHODS: A total 160 stents (Bare-metal stents (BMS), polymer-free probucol stents (PrES), sirolimus-eluting stents (SES) and DDES) were randomly implanted in the coronary arteries of 80 pigs...

Aspirin, the first antiplatelet agent, has been around since the 19th century, and is one of the most established drugs in history. With the improvement of coronary interventions in the past few decades, there has been more reliance on oral antiplatelet agents to reduce complications of in-stent restenosis/thrombosis. Clopidogrel was initially introduced in 1997, and within the past seven years, two additional oral antiplatelet agents have been approved by the U.S. Food and Drug Administration. With more potent antiplatelet agents comes increased risks of adverse effects...

OBJECTIVES: We sought to compare the efficacy and safety of prasugrel and ticagrelor in patients with coronary artery disease undergoing percutaneous coronary intervention (PCI). BACKGROUND: Evidence from randomized head-to-head comparison between prasugrel and ticagrelor is rare regarding clinical endpoints. METHODS: PubMed, the Cochrane Library, and Web of Science were queried with the terms "prasugrel," "ticagrelor," and "randomized." Relevant randomized controlled trials (RCTs) or the same terms were also surveyed using clinicaltrials...

BACKGROUND: Older patients treated with percutaneous coronary intervention are at increased risk of periprocedural events. METHODS AND RESULTS: CHAMPION (cangrelor versus standard therapy to achieve optimal management of platelet inhibition) PHOENIX randomized 11 145 patients to cangrelor or clopidogrel. We sought to determine the outcomes in the prespecified subgroup of patients ≥75 years old (n=2010; 18%). Cangrelor resulted in directionally consistent effects on the primary end point (death, myocardial infarction, ischemia-driven revascularization, or stent thrombosis) in patients ≥75 years old (odds ratio [OR], 0...
