BACKGROUND: The novel nonsteroidal mineralocorticoid receptor (MR) antagonist finerenone holds promise to be safe and efficient in the treatment of patients with heart failure and/or chronic kidney disease. However, its effects on vascular function remain elusive. PURPOSE: The aim of this study was to determine the functional effect of selective MR antagonism by finerenone in vascular cells in vitro and the effect on vascular remodeling following acute vascular injury in vivo...

BACKGROUND: The early impact of renal transplantation on subclinical cardiovascular measures in pediatric patients has not been widely investigated. This analysis is performed for pediatric patients participating in the prospective 4C study and focuses on the early effects of RRT modality on cardiovascular comorbidity in patients receiving a preemptive transplant or started on dialysis. METHODS: We compared measures indicating subclinical cardiovascular organ damage (aortal pulse wave velocity, carotid intima media thickness, left ventricular mass index) and evaluated cardiovascular risk factors in 166 pediatric patients before and 6 to 18 months after start of RRT (n=76 transplantation, n=90 dialysis)...

OBJECTIVE: Quantification of retinal vessel morphology has emerged as a marker of cardiovascular health. We examined retinal microvascular diameters in RA, particularly in regard with systemic inflammation, subclinical atherosclerosis and cardiovascular risk. METHODS: Retinal images from RA patients and controls were processed using computerized software, to obtain central retinal arteriolar (CRAE) and venular (CRVE) equivalent and arteriovenous ratio (AVR). Subclinical atherosclerosis was assessed with carotid intima-media thickness (cIMT), and 10-year risk of general cardiovascular disease was calculated...

Background Ultrasound imaging is able to quantify carotid arterial wall structure for the assessment of cerebral and cardiovascular disease risks. We describe a protocol and quality assurance process to enable carotid imaging at large scale that has been developed for the UK Biobank Imaging Enhancement Study of 100,000 individuals. Design An imaging protocol was developed to allow measurement of carotid intima-media thickness from the far wall of both common carotid arteries. Six quality assurance criteria were defined and a web-based interface (Intelligent Ultrasound) was developed to facilitate rapid assessment of images against each criterion...

Depending on the adequacy of collateral sources of blood flow, arterial stenosis or occlusion may lead to reduced perfusion pressure and ultimately reduced blood flow in the distal territory supplied by that vessel. There are two well-defined compensatory mechanisms to reduced pressure or flow - autoregulatory vasodilation and increased oxygen extraction fraction. Other changes, such as metabolic downregulation, are likely. The positive identification of autoregulatory vasodilation and increased oxygen extraction fraction in humans is an established risk factor for future ischemic stroke in some disease states such as atherosclerotic carotid stenosis and occlusion...

Excessive migration of vascular smooth muscle cells (VSMCs) after vascular injury contributes to the development of occlusive vascular disease. Inhibition of VSMC migration is a validated therapeutic modality for occlusive vascular diseases, such as atherosclerosis and restenosis. We investigated the inhibitory effect of chebulinic acid (CBA) on cell migration and matrix metalloproteinase (MMP)-2 activation in platelet-derived growth factor (PDGF)-BB-induced mouse and human VSMCs. CBA significantly inhibited PDGF-BB-induced migration in mouse and human VSMCs, without inducing cell death...

Vascular aging, as assessed by structural and functional arterial properties, is an independent predictor of cardiovascular risk. We hypothesized that the number of cardiovascular risk factors determines the progression of vascular aging. One hundred forty-two subjects (mean age 51.9 years, 94 men) without established cardiovascular disease were investigated in 2 examinations over a 2-year period. Subjects were classified at baseline according to their number of risk factors (from 0 to 2 and more). Subjects had determinations of carotid-femoral pulse wave velocity, aortic augmentation index, brachial flow-mediated dilatation, and common carotid intima-media thickness and their annual absolute changes were calculated...

BACKGROUND: Cardiovascular disease is the major cause of death in patients with chronic kidney disease, even after renal transplantation. Cardio-ankle vascular index (CAVI) provides an indicator of arterial stiffness, whereas fibroblast growth factor-21 (FGF-21) levels may provide a biomarker for atherosclerotic disease. We investigated the association between CAVI and FGF-21 and their relationships to carotid intima-media thickness (IMT) and other cardiovascular risk factors. METHODS: This study included 90 renal transplant patients...

A 78-year-old Caucasian man with significant vascular disease reported sudden onset of worsened vision during a routine wound-care appointment for non-healing necrotic leg ulcers. He described painless blurring of vision with grey scotomas in his RE, his only well-seeing eye, following trauma to the LE as a child. He presented with retinal ischemia, a cotton-wool spot and optic nerve swelling. Temporal artery biopsy showed myxoid degeneration and extensive calcium deposition which also was shown on imaging throughout his carotid and vertebral arterial system, the clinical picture of calciphylaxis...

BACKGROUND: Central arterial stiffness has been shown to play a key role in cardiovascular disease. However, evidence regarding such arterial stiffness from various arterial segments in relation to B-type natriuretic peptide (BNP) remains elusive. METHODS: A total of 1255 participants (47.8% men; mean age: 62.6 ± 12.3 [SD] years) with preserved left ventricular function (ejection fraction ≥50%) and ≥1 risk factors were consecutively studied. Arterial pulse wave velocity (PWV) by automatic device (VP-2000; Omron Healthcare) for heart-femoral (hf-PWV), brachial-ankle (ba-PWV), and heart-carotid (hc-PWV) segments were obtained and related to BNP concentrations (Abbott Diagnostics, Abbott Park, IL, USA)...

Cerebral hypoperfusion is an important factor in the pathogenesis of cerebrovascular diseases and neurodegenerative disorders. We investigated the effects of memantine and rosuvastatin on both neovascularization and synaptic function in a rat model of chronic cerebral hypoperfusion, which was established by the bilateral common carotid occlusion (2VO) method. We tested learning and memory ability, synaptic function, circulating endothelial progenitor cell (EPC) number, expression of neurotrophic factors, and markers of neovasculogenesis and cell proliferation after memantine and/or rosuvastatin treatment...

Carotid intima-medial thickness has long been proposed as a surrogate marker of atherosclerotic vascular disease in other vascular beds, most notably the coronary arteries with its practical implications. This observational study aimed at exploring the relationship of a hypothetical stronger relationship of carotid intima-medial thickness with coronary artery disease in diabetic patients than non-diabetic counterparts. Thirty diabetic patients and 74 non-diabetic patients who were referred for coronary angiogram in the Departments of Cardiology Bangabandhu Sheikh Mujib Medical University and Combined Military Hospital, Dhaka Cantonment, Bangladesh from January, 2002 and December, 2003 were studied...

The carotid artery is one of the major supply routes of blood to the brain and a common site of vascular disease. Obstructive and sclerotic disorders within the carotid artery impact local blood flow patterns as well as overall impedance and blood supply to the brain. A lumped parameter model and an experimental in-vitro flow loop were used to study the effects of local stenosis and stiffness in the carotid artery based on a family of phantoms with different degrees of stenosis and compliance. The model also allows independent examination of the effects of downstream resistance and compliance...

BACKGROUND: Intracerebral hemorrhage (ICH) in the context of cerebral hyperperfusion syndrome (CHS) is an uncommon but potentially lethal complication after carotid revascularization for carotid occlusive disease. Information about its incidence, risk factors and fatality is scarce. Therefore, we aimed to perform a systematic review and meta-analysis focusing on the incidence, risk factors and outcomes of ICH in the context of CHS after carotid revascularization. METHODS: We searched the PubMed and EBSCO hosts for all studies published in English about CHS in the context of carotid revascularization...

Epidemiological studies have reported associations between traditional cardiovascular risk factors and carotid intima-media thickness (CIMT) or carotid plaque. However, definite risk factors at different phases of carotid atherosclerosis remain controversial. We aimed to explore risk factors and characteristics of carotid atherosclerosis at different stages in a low-income population with a high incidence of stroke in China. Between April 2014 and January 2015, we recruited 3789 stroke-free and cardiovascular disease-free residents aged ≥ 45 years...

OBJECTIVE: hnRNPA1 (heterogeneous nuclear ribonucleoprotein A1) plays a variety of roles in gene expression. However, little is known about the functional involvement of hnRNPA1 in vascular smooth muscle cell (VSMC) function and neointima hyperplasia. In this study, we have attempted to investigate the functional roles of hnRNPA1 in the contexts of VSMC function, injury-induced vessel remodeling, and human atherosclerotic lesions, as well as discern the molecular mechanisms involved. APPROACH AND RESULTS: hnRNPA1 expression levels were consistently modulated during VSMC phenotype switching and neointimal lesion formation induced by wire injury...
