BACKGROUND AND AIMS: Vascular disease (VD), as assessed by history of myocardial infarction or peripheral artery disease or aortic plaque, increases stroke risk in atrial fibrillation (AF), and is a component of risk assessment using the CHA2DS2-VASc score. We investigated if systemic atherosclerosis as detected by ultrasound carotid plaque (CP) could improve the predictive value of the CHA2DS2-VASc score. METHODS: We analysed data from the ARAPACIS study, an observational study including 2027 Italian patients with non-valvular AF, in whom CP was detected using Doppler Ultrasonography...

OBJECTIVE: Recently, poliovirus receptor-related 2 (Pvrl2) emerged as a top gene in a global gene expression study aiming to detect plasma cholesterol-responsive genes causally related to atherosclerosis regression in hypercholesterolemic mice. PVRL2 is an adherens junction protein implied to play a role in transendothelial migration of leukocytes, a key feature in atherosclerosis development. In this study, we investigated the effect of Pvrl2 deficiency on atherosclerosis development and transendothelial migration of leukocytes activity...

OBJECTIVE: Although rapid progression of coronary atherosclerosis was observed in chronic cocaine users, it is unknown whether reduced cocaine use retards the progression of atherosclerosis. We investigated whether reduced cocaine use over a 12-month period was associated with coronary plaque regression in cocaine users. METHODS: Fifteen African American chronic cocaine users with previously coronary computed tomography angiography (CCTA)-confirmed >50% coronary stenosis in Baltimore, Maryland, were enrolled in a study to investigate whether reduced cocaine use is associated with changes in coronary plaque burden over a 12-month period of cash-based incentive intervention, which was implemented to systematically reinforce cocaine abstinence...

HDL efflux capacity and particle size are associated with atherosclerotic cardiovascular disease events in middle age, however it is unclear if these associations are present at older ages. We sampled 402 Chicago Healthy Aging Study participants who underwent carotid MR assessment for lipid rich necrotic core plaque (LRNC). We measured HDL particle size, HDL particle number, and HDL efflux capacity. We quantified the associations between HDL particle size and HDL efflux and the presence of LRNC and HDL particle number, and HDL efflux capacity using adjusted linear and logistic regression models...

BACKGROUND: Retrograde brain embolization from complex plaques of the proximal descending aorta (DAo) has been identified as a new potential mechanism of stroke. Our purpose was to identify predictors of increased retrograde aortic blood flow indicating an elevated risk of brain embolization from the DAo. METHODS: A total of 485 patients with acute ischemic stroke were prospectively included and underwent transesophageal echocardiography. Blood flow velocities in the proximal DAo were studied using 2D pulse-wave Doppler ultrasound...

BACKGROUND: Phenotypic expressions of arterial disease vary throughout the body and it is not clear to what extent systemic atherosclerosis influences brain arterial remodeling. We aim to test the hypothesis that systemic atherosclerosis is associated with brain arterial diameters. METHODS: Stroke-free participants in the Northern Manhattan Study MRI subcohort in whom carotid ultrasound, transthoracic echocardiogram, and brain MRA (n = 482) were performed were included in this analysis...

The history of proprotein convertase subtilisin/kexin type 9 (PCSK9) in medical science is fascinating and the evolution of knowledge of its function has resulted in new medications of major importance for the cardiovascular (CV) patient. PCSK9 functions as a negative control or feedback for the cell surface receptors for low-density lipoprotein including its component of cholesterol (LDL-C). The initial and key findings were that different abnormalities of PCSK9 can result in an increase or a decrease of LDL-C because of more or less suppression of cell surface receptors...

BACKGROUND AND AIMS: Apelin-APJ signaling reduces cardiovascular disease (CVD) risk. In rheumatoid arthritis (RA), the atherosclerosis burden and plaque vulnerability to rupture are increased. We explored relationships between apelin concentrations and subclinical CVD in RA. METHODS: Apelin levels were measured in 235 (114 black, 121 white) RA patients. Associations between apelin concentrations and ultrasound determined carotid artery intima-media thickness (cIMT) and plaque, and levels of matrix metalloproteinase (MMP)-2 and -9 that mediate plaque stability and vulnerability respectively, were identified in confounder adjusted multivariate regression analysis...

BACKGROUND: Coronary lipid core plaque may be associated with the incidence of subsequent cardiovascular events. METHODS: We analyzed outcomes of 239 patients who underwent near-infrared spectroscopy (NIRS) coronary imaging between 2009-2011. Multivariable Cox regression was used to identify variables independently associated with the incidence of major adverse cardiovascular events (MACE; cardiac mortality, acute coronary syndromes (ACS), stroke, and unplanned revascularization) during follow-up...

It is well known that phospholipid transfer protein (PLTP) is involved in the lipid metabolism and development of atherosclerosis (AS). Abundant PLTP is considered to be expressed on the foam cells derived from monocyte/macrophages in atherosclerotic plaques, suggesting that high level of active PLTP may promote the formation of foam cells. However, the exact role of PLTP on the process of macrophage derived foam cell formation remains unclear. The accumulation of free cholesterol (FC) in the cytoplasm may lead to the prolonged endoplasmic reticulum stress (ERs) and the imbalance of intracellular cholesterol homeostasis...

This split-mouth randomized clinical trial aimed to compare the survival rate of bonding and banding molar tubes in adult orthodontic patients. Eligibility criteria included adults (aged >18 years), no active caries, restorations, or fractures in the upper and lower molars. The main outcome was any type of first-time failure in molar tubes. A computer-generated randomization scheme was used in a 1:1 ratio. The survival rate was estimated for 32 adult patients, in whom a tube was bonded to a molar tooth using composite resin on one side and a band was cemented with glass ionomer onto the same tooth in the contralateral arch...

BACKGROUND AND AIMS: Although comprehensive risk factor modification is recommended, a uniform management strategy does not necessarily prevent secondary events in patients with coronary artery disease (CAD). Therefore, identification of high-risk patients who may benefit from more intensive interventions may improve prognosis. Carotid ultrasound can reliably identify systemic atherosclerosis, and carotid plaque and intima-media thickness (IMT) are known independent risk factors for CAD...

Atherosclerosis often leads to myocardial infarction and stroke. We examined the influence of baseline plaque characteristics on subsequent vascular remodeling in response to changes in plaque size. Using optical coherence tomography (OCT) and intravascular ultrasound (IVUS), we examined 213 plaques from 138 patients with acute coronary syndrome at baseline and repeated IVUS at the 12-month follow-up. The change in external elastic membrane (EEM) area for each 1 mm2 change in plaque area (i.e., the slope of the regression line) was calculated as a measure of vascular remodeling capacity...

Imaging-pathological correlation studies show that in vivo amyloid-β (Aβ) positron emission tomography (PET) strongly predicts the presence of significant Aβ pathology at autopsy. We sought to determine whether regional PiB-PET uptake would improve sensitivity for amyloid detection in comparison with global measures (experiment 1), and to estimate the relative contributions of different Aβ aggregates to in vivo PET signal (experiment 2). In experiment 1, 54 subjects with [(11)C] PiB-PET during life and postmortem neuropathologic examination (85...
