BACKGROUND AND AIMS: The Neutrophil-to-Lymphocyte Ratio (NLR), an index of systemic inflammation, has been reported to be associated with subclinical atherosclerosis, but its predictive role of the presence of carotid atherosclerotic plaques remains undefined. This study aims to assess this association which gives additional value to this biomarker, with respect to the main risk factors, in the prediction of carotid atherosclerosis in older adults. METHODS AND RESULTS: We recruited 324 patients, aged ≥65 years, without hematopoietic disorders, and/or history of malignancies, evidence of acute infections, chronic inflammatory status, and history of glucocorticoid therapy within the past three months, hospitalized in the Unit of Internal Medicine, University of Catania, Catania, Italy from January 2014 to December 2016...

BACKGROUND: Absence of cardiovascular risk factors (CVRFs) is traditionally considered low risk for atherosclerosis; however, individuals without CVRFs, as currently defined, still have events. OBJECTIVES: This study sought to identify predictors of subclinical atherosclerosis in CVRF-free individuals. METHODS: Participants from the PESA (Progression of Early Subclinical Atherosclerosis) study (n = 4,184) without conventional CVRFs were evaluated (n = 1,779; 45...

OBJECTIVES: The objective of this meta-analysis is to evaluate clinical efficacy of double layered mesh covered carotid stent systems in the clinical practice. BACKGROUND: The need for an increase plaque coverage to decrease the risk of debris dislodgement through the stent struts, following carotid artery stenting (CAS), has brought to the design of a new generation of double layered carotid stents. Several small sized clinical studies evaluating two different devices have been recently published, unfortunately these are not sufficiently powered to test for device related and clinical endpoints and no comparison, between the two available devices, has been reported yet...

Carotid artery stenting (CAS) is increasingly utilized in patients with carotid artery stenosis. Various intraprocedural and postprocedural complications have been reported in the literature. We present a case of symptomatic major thromboembolism after CAS. The intraprocedural angiogram showed extraordinary slow filling of the contrast medium into the plaque, which we named as "crevice sign." An 83-year-old man presented repeat right amaurosis fugax for 6 months. The radiological examinations revealed 85% stenosis of the origin of the right internal carotid artery...

BACKGROUND AND AIMS: Mast cells have been implicated in the development and progression of atherosclerosis in animal models and human autopsy studies. However, it is unknown whether long-term exposure to excess of mast cells is associated with cardiovascular disease (CVD) in humans. Our objective was to compare the prevalence of CVD and cardiovascular risk factors in patients with systemic mastocytosis (SM) and controls. METHODS: In 50 patients with SM and 50 age and sex matched controls, the history of CVD and presence of cardiovascular risk factors were assessed...

BACKGROUND: Carotid intima-media thickness (cIMT) is a significant early prediction signal for preclinical atherosclerosis. Plasma homocysteine (Hcy) level is an independent risk factor for cardiovascular diseases. Pulse wave velocity (PWV), an index of arterial stiffness (AS), has showed its value in the evaluation of AS in vascular-related diseases. The data regarding the relationships between cIMT and other indices of vascular damage are limited and partly controversial. We aim to investigate the relationships between cIMT and other indices of vascular damage such as Hcy and carotid femoral PWV (CF-PWV)...

Background Increased pulse pressure is associated with structural target organ damage, especially in elderly patients, increasing cardiovascular risk. Design In this analysis, we investigated whether high pulse pressure retains a prognostic effect also when common markers of target organ damage are taken into account. Methods We analysed an unselected cohort of treated hypertensive patients from the Campania Salute Network registry ( n = 7336). Participants with available cardiac and carotid ultrasound were required to be free of prevalent cardiovascular disease, with ejection fraction ≥50%, and no more than stage III Chronic Kidney Disease...

INTRODUCTION: Fatty liver disease (FLD) is correlated with cardiovascular disease. Carotid intima-media thickness (CIMT) and coronary artery calcium score (CACS) can noninvasively identify subclinical atherosclerosis and predict risk for cardiovascular events. This study evaluated CIMT and CACS measurements to detect subclinical atherosclerosis in patients with and without FLD. METHODS: Patients who underwent carotid and abdominal ultrasounds as well as cardiac computed tomography (CT) scans were evaluated retrospectively...

Hemorrhage and lipid deposits contribute to instability in atherosclerotic plaques. Unstable carotid artery plaques can lead to cerebral ischemic events. While MRI studies have shown the ability to identify plaque components, the identification of hemorrhage and lipids has proven to be problematic. The purpose of this study was to quantitatively evaluate the potential of the MRI fat/water separation method known as iterative decomposition of water and fat with echo asymmetry and least squares estimation (IDEAL) to complement and improve existing methods for the identification of hemorrhage and lipids in carotid artery plaques...

Our previous study demonstrated that coagulation factor Xa (FXa) induced endothelial cell senescence, resulting in inflammation and impaired angiogenesis. This mechanism is dictated through protease-activated receptors, PARs, insulin-like growth factor-binding protein 5 (IGFBP-5), and p53. Activation of PARs contributes to the pathophysiology of several chronic inflammatory diseases, including atherosclerosis. Thus, we speculated that similar mechanism might participate in the progression of atherosclerotic plaques...

BACKGROUND: There is currently no consensus on the methodology for quantification of 18F-FDG uptake in inflammation in atherosclerosis. In this study, we explore different methods for quantification of 18F-FDG uptake in carotid atherosclerotic plaques and correlate the uptake values to histological assessments of inflammation. METHODS AND RESULTS: Forty-four patients with atherosclerotic stenosis ≥70% of the internal carotid artery underwent 18F-FDG PET/CT. Maximum standardized uptake values (SUVmax) from all plaque-containing slices were collected...

Rationale: The interaction of circulating cells within the vascular wall is a critical event in chronic inflammatory processes such as atherosclerosis, but the control of the vascular inflammatory state is still largely unclear. Objective: This study was undertaken to characterize the function of the endothelial-enriched microRNA miR-100 during vascular inflammation and atherogenesis. Methods and Results: Based on a transcriptome analysis of endothelial cells after miR-100 overexpression, we identified miR-100 as potent suppressor of endothelial adhesion molecule expression, resulting in attenuated leukocyte-endothelial interaction in vitro and in vivo as shown by flow cytometry and intravital imaging approach...

PURPOSE: Hemodynamics has a key role in atheropathogenesis. Indeed, atherosclerotic phenomena occur in vessels characterized by complex geometry and flow pattern, like the carotid bifurcation. Moreover, lifestyle is a significant risk factor. The aim of this study is to evaluate the hemodynamic effects due to two sedentary lifestyles - sitting and standing positions - in the carotid bifurcation in order to identify the worst condition and to investigate the atherosclerosis incidence. METHODS: The computational fluid dynamics (CFD) was chosen to carry out the analysis, in which in vivo non-invasive measurements were used as boundary conditions...

Carotid and coronary artery disease are two major atherosclerotic conditions that have shown an increased prevalence in the last three decades that is associated with high morbidity and mortality. Recent data have revealed that the development of the atherosclerotic plaque-the basic entity in both diseases-may share similar characteristics and mechanisms irrespective of the location site. Even though the biology of atherosclerotic process is similar, there are differences in plaque morphology and characteristics...
