Animal models of disease are an indispensable element in our quest to understand pathophysiology and develop novel therapies. Ex vivo studies have severe limitations, in particular their inability to study individual disease progression over time. In this respect, non-invasive in vivo technologies offer multiple advantages. We here used bilateral common carotid artery occlusion (BCCAO) in mice, an established model for ischemic retinopathy, and performed a multimodal in vivo and ex vivo follow-up. We used scanning laser ophthalmoscopy (SLO), ocular coherence tomography (OCT) and electroretinography (ERG) over 6 weeks followed by ex vivo analyses...

Optimal management of patients with stroke due to symptomatic carotid artery disease coexistent with bacterial endocarditis is still not well established. We report the case of a patient who presented with multifocal left middle cerebral artery stroke in the setting of Enterococcus faecalis endocarditis and was found to have near-occlusive ipsilateral carotid artery stenosis in stroke workup. Carotid artery endarterectomy was performed, and atheroma material demonstrated complicated plaque with cultures positive for E...

Kawasaki disease (KD) is a systemic vasculitis with a predilection for damage to the coronary arteries. In the acute phase, clinical decision making for KD relies on the measurements of the coronary z-score obtained by 2-dimensional echocardiography (2DE). In the convalescent phase, KD patients with coronary artery abnormalities (CAAs) eventually show arteriosclerotic vascular remodeling characterized by marked intimal proliferation and neoangiogenesis after KD vasculitis, which often induces myocardial ischemia...

BACKGROUND: Apolipoprotein C-III (apoC-III), a small proinflammatory protein present on 6% to 7% of high-density lipoprotein (HDL) particles, defines a subspecies of HDL adversely associated with coronary heart disease in primarily white cohorts. In a multi-ethnic population free of clinical cardiovascular disease, we evaluated the relationship between apoC-III-defined HDL subspecies and subclinical markers of atherosclerotic pathology. METHODS AND RESULTS: We investigated cross-sectional associations between apolipoprotein A-I concentrations of apoC-III-defined HDL subspecies, measured via ELISA and imaging measures of subclinical atherosclerosis, among 4659 participants in the MESA (The Multi-Ethnic Study of Atherosclerosis) at baseline (2000-2002)...

BACKGROUND: Kawasaki disease (KD) has a predilection to involve coronary arteries, leading to several long-term cardiovascular sequelae. Apart from coronary artery abnormalities, children with KD are also prone to develop premature atherosclerosis, endothelial dysfunction, and lipid abnormalities. Some of these complications may occur even in children who have received appropriate treatment with intravenous immunoglobulin in the acute phase. METHODS: In 2009, we had studied carotid intima-media thickness (cIMT) and lipid profile in 27 children with KD at least 1 year after the acute episode...

INTRODUCTION: Type 2 diabetes mellitus (T2DM) and obesity are both related to increased risk of cardiovascular disease and mortality. Early atherosclerotic vascular changes can be detected by non-invasive tests like carotid artery intima-media thickness (cIMT) and pulse wave velocity (PWV). Both cIMT and PWV are significantly impaired in T2DM patients and in obese patients, but the additional effect of T2DM on these vascular measurements in obese subjects has not been evaluated. METHODS: Two hundred morbidly obese patients with or without T2DM were enrolled in a prospective cohort study and underwent extensive laboratory testing, including cIMT and PWV measurements...

This study aimed to investigate the discrepancy between pulse wave velocity (PWV) and pulse pressure amplification (PPA) in association with hypertensive target organ damage (TOD) in the elderly. From June 2014 to August 2015, 1599 participants aged >65 years old from communities located in northern Shanghai were recruited. Carotid-femoral pulse wave velocity (cfPWV), peripheral blood pressure (BP), central BP and other TOD indicators, including the ratio of the early ventricular filling velocity (E) to the peak velocity of the tissue Doppler velocity of septal mitral annulus (E/Ea), left ventricular mass index (LVMI), carotid intima-medium thickness (CIMT), estimated glomerular filtration rate (eGFR), and urinary albumin-creatinine ratio (ACR), were determined for each participant...

<u>Rationale:</u> One measure of protein glycosylation (GlycA) has been reported to predict higher cardiovascular risk by reflecting inflammatory pathways <u>Objective:</u> To assess the role of a comprehensive panel of immunoglobulin (IgG) glycosylation traits on traditional risk factors for cardiovascular disease and on presence of subclinical atherosclerosis in addition to GlycA. <u>Methods and Results:</u> We measured 76 IgG glycosylation traits in 2970 women (age range 40-79 years) from the TwinsUK cohort and correlated it to their estimated 10-year atherosclerotic cardiovascular disease (ASCVD) risk score and their carotid and femoral plaque measured by ultrasound imaging...

Abnormal cerebral blood flow (CBF) is implicated in several neonatal and infant diseases. However, measurement of CBF in this population remains difficult and has not been used in routine clinical MRI. Arterial spin labeling (ASL) methods suffer from both low SNR and poor quantification when applied to very young children. Furthermore, rapid change in brain physiology in this age range makes it difficult to choose sequence parameters such as labeling pulse flip angle and post labeling delay. Phase-contrast (PC) MRI is another approach to measure flow...

Prenatal, neonatal meningoencephalitis and infections of the brain in older infants are often associated with serious complications which can be diagnosed by sonography through the open fontanelles. Most frequently postmeningitic hydrocephalus and subdural effusions occur. Rarer complications are brain abscesses and ventriculitis which are caused by gram negative bacteria such as E. coli, Serratia marcescens, Proteus and Enterobacter. A serious complication after ventriculitis is the development of compartment hydrocephalus...

AIMS: Atherosclerosis is associated with altered circulating microRNA profiles. It is yet unclear whether the expression of these potential biomarkers differs according to the location of atherosclerosis. We assessed whether atherosclerosis of different arterial territories, except the coronary, is associated with specific circulating microRNA profiles. METHODS: A systematic search in PubMed, Web of Science, Embase, and Cochrane Library was carried out using a retrieval strategy including MESH and non-MSH terms...

Predictors of adverse cardiovascular outcomes include elevated nighttime systolic blood pressure (SBP) and a non-dipping pattern. We investigated whether these factors correlate with systemic inflammation, cardiovascular risk, and markers of central and peripheral vascular damage in rheumatoid arthritis (RA), a disease characterized by excess cardiovascular risk. Twenty-four-hour ambulatory blood pressure monitoring was applied in patients and controls. Vascular assessments included measurement of arterial stiffness (pulse wave velocity) and carotid atherosclerosis (carotid intima-media thickness)...

BACKGROUND: Carotid artery plaque is associated with coronary artery disease (CAD). Besides the presence of plaque, plaque characteristics is also related to the severity of CAD. So the characteristic difference of carotid plaque may affect this assessment role. However, it is unclear whether the maximum carotid plaque area can reflect the extents and severity of CAD. METHODS: We enrolled 388 consecutive CAD patients and 45 controls, and 204 patients were studied after excluding 184 patients without carotid plaque or coronary angiogram...

BACKGROUND AND OBJECTIVES: Atherosclerosis is highly prevalent in CKD. The rate of progression of atherosclerosis is associated with cardiovascular events. Fibroblast growth factor 2 (FGF-2) is a member of the FGF family with potentially both protective and deleterious effects in the development of atherosclerosis. The role of circulating FGF-2 levels in the progression of atherosclerosis in CKD is unknown. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We used a multicenter, prospective, observational cohorts study of 481 patients with CKD...

Central nervous system (CNS) ischemic events, besides being a common and devastating disease, are accompanied by severe disability and other morbidities. The cause of such events is not always that simple to diagnose, and among the young, a broad spectrum of possibilities should be considered. We present the case of a young man who presented two episodes of CNS ischemia with a 1 year gap between them, which occurred in the same situation while he was walking and carrying a heavy backpack. The second event first presented as a transient ischemic attack followed by a stroke the day after...
