BACKGROUND: The renin-angiotensin-aldosterone system is increasingly being recognized to play an important role in the development and clinical course of cardiovascular diseases. Renin-angiotensin-aldosterone system activation is associated with clinical outcome in various populations of cardiovascular patients, such as patients with coronary artery, peripheral artery, and cerebrovascular disease. In this study, we investigated the associations between plasma renin and aldosterone concentrations and atherosclerotic plaque characteristics and secondary vascular events in patients undergoing carotid endarterectomy...

BACKGROUND: Cerebrovascular disease caused by atherosclerosis affecting cerebral and pre-cerebral arteries is one of the leading causes of morbidity and mortality in high-income countries. Medications of botanical origin are often characterized by good tolerability and are suitable for long-term treatment. Therefore, phytotherapy provides an interesting possibility for developing new therapies for prevention of atherosclerosis and its complications that could be used at preclinical stages of the disease...

Background Large vessel disease stroke subtype carries the highest risk of early recurrent stroke. In this study we aim to look at the association between impaired perfusion and early stroke recurrence in patients with intracranial atherosclerotic disease or total cervical carotid occlusion. Methods This is a retrospective study from a comprehensive stroke center where we included consecutive patients 18 years or older with intracranial atherosclerotic disease or total cervical carotid occlusion admitted with a diagnosis of ischemic stroke within 24 h from symptom onset with National Institute Health Stroke Scale < 15, between 1 December 2016 and 30 June 2017...

BACKGROUND: Endothelial dysfunction has been identified as an etiologic factor for osteonecrosis of the femoral head (ONFH) and major adverse cardiovascular and cerebrovascular events (defined as major cardiovascular disease [CVD] and cerebrovascular accident [CVA]). However, the incidence of major adverse cardiovascular and cerebrovascular events in patients with nontraumatic ONFH and any association between the two diagnoses remain unclear. QUESTIONS/PURPOSES: We compared a large cohort of patients with nontraumatic ONFH and a matched control group without this diagnosis and (1) examined the frequency and hazard ratio (HR) of major adverse cardiovascular and cerebrovascular events in both groups adjusted for age, sex, socioeconomic status, and associated comorbidities (which we defined as the adjusted HR), (2) determined whether any association of ONFH and major adverse cardiovascular and cerebrovascular events was stable after adjusting for confounding variables, and (3) compared the occurrence of major adverse cardiovascular and cerebrovascular events with time in both groups...

It is estimated that more than 200 million individuals are affected by lower extremity artery disease (LEAD) worldwide. This prevalence has increased between 2000 and 2010 by 25%, especially in low/middle income countries. In France, about one million people are affected by this condition. Almost two-thirds of patients with LEAD are asymptomatic. This explains the interest of the measurement of the ankle-brachial index (ABI), an objective and harmless diagnostic tool. An ABI≤0.90 is considered as diagnostic for LEAD...

BACKGROUND: Atherosclerosis (AS) is a common pathological basis of various cardiovascular and cerebrovascular diseases. Plaque formation is initiated and triggered by vascular smooth musclecells (VSMCs) migration in vascular wall, which gradually aggravates atherosclerosis progression. Absent in melanoma 2 (AIM2), a member of HIN-200 family, plays an important role in activating inflammasome. However, the role of AIM2 in atherosclerotic plaque progression outside of the inflammasome has not yet been reported...

Background: Both hypertensive and atherosclerotic processes contribute to common carotid artery intima-media thickness (CCA-IMT). Elevated CCA-IMT may be indicative of subclinical cerebrovascular disease; however, its role in the absence of concomitant carotid artery plaque is uncertain, and few studies have examined associations in black populations. Materials and Methods: At cohort visit 3 (1993-1995) a subset of stroke-free participants (641 blacks and 702 whites, mean age 63) from the Atherosclerosis Risk in Communities (ARIC) study was imaged by brain MRI and carotid ultrasound...

BACKGROUND: In dementia with Lewy bodies (DLB) and Parkinson's disease with dementia (PDD), it is still debated whether white matter hyperintensities (WMH) on MRI reflect atherosclerotic cerebrovascular changes or Alzheimer's disease (AD)-related pathology such as cerebral amyloid angiopathy. To examine AD-related pathology in DLB and PDD, we compared the severity of WMH and medial temporal lobe atrophy among patients with DLB, PDD, non-demented PD (PDND), and AD. METHODS: We retrospectively studied sex- and age-matched outpatients with AD, DLB, PDD, and PDND, as well as subjects without central nervous system disorders as normal controls (n=50 each)...

BACKGROUND: The risks of atherosclerotic cardiovascular and cerebrovascular diseases in women rapidly increase with age in post-menopausal women. We aimed to investigate the lipid profiles in peri-menopausal women with cerebral infarction and to explore the effects of atorvastatin intervention. METHODS: We collected women aged 40-60 with cerebral infarction between January 2013 and December 2016. Atorvastatin was applied for 6 months in all included patients. Blood lipid profiles, serum pro-inflammation cytokines, intracranial plaque and NIH stroke scale (NIHSS) scores were evaluated before and after atorvastatin treatment...

Due to the complex profile of atherosclerotic risk factors, an integrated analysis of a specific individual is difficult. Endothelial function reflects a composite of various risk factors, and may be used as an optimal tool to estimate the overall atherosclerotic risk. In this study, we investigated the value of digital Reactive Hyperemia Index (RHI) in an actual population with multiple atherosclerotic risk factors or coronary artery disease (CAD). A total of 417 patients from the Seoul National University Boramae Medical Center RHI registry were enrolled in this study...

This pilot study aimed to investigate the utility of near-infrared spectroscopy/indocyanine green (NIRS/ICG) for examining patients with occlusive cerebrovascular disease. Twenty-nine patients with chronic-stage atherosclerotic occlusive cerebrovascular disease were included. The patients were monitored using NIRS at the bedside. Using ICG time-intensity curves, the affected-to-unaffected side ratios were calculated for several parameters, including the maximum ICG concentration (ΔICGmax), time to peak (TTP), rise time (RT), and blood flow index (BFI = ΔICGmax/RT), and were compared to the affected-to-unaffected side ratios of the regional cerebral blood flow (rCBF) and regional oxygen extraction fraction (rOEF) obtained using positron emission tomography with 15O-labeled gas...

Commensal gut microbiota have recently been implicated in cardiovascular disease (CVD) and cerebrovascular disease. Atherosclerotic plaque formation depends on the colonization status of the host. In addition to host nutrition and the related microbiota-dependent metabolic changes, activation of innate immune pathways triggers the development of atherosclerosis and supports arterial thrombosis. Gnotobiotic mouse models have uncovered that activation of Toll-like receptor-2 by gut microbial ligands supports von Willebrand factor-integrin mediated platelet deposition to the site of vascular injury...

BACKGROUND: 4D flow MRI is a relatively quick method for obtaining wall shear stress (WSS) in vivo, a hemodynamic parameter which has shown promise in risk stratification for rupture of cerebrovascular diseases such as intracranial aneurysms and atherosclerotic plaques. The accuracy of such measurements is still largely unknown. OBJECTIVE: To quantify the accuracy of 4D flow MRI-derived wall shear stress values for intracranial aneurysms and carotid bifurcations...

Cardiovascular disease remains the leading cause of disease burden globally, which underlies the continuing need to identify new complementary targets for prevention. Over the past 5-10 years, the pooling of multiple data sets into 'mega-studies' has accelerated progress in research on stress as a risk and prognostic factor for cardiovascular disease. Severe stressful experiences in childhood, such as physical abuse and household substance abuse, can damage health and increase the risk of multiple chronic conditions in adulthood...

BACKGROUND AND AIMS: Non-alcoholic fatty liver disease is recognized not only as part of the metabolic syndrome but also as an independent predictor of cardiovascular disease. METHODS: In this study, NMR spectroscopy method, together with perfusion techniques, was used to detect subclinical brain vascular damage in subjects with NAFLD without overt atherosclerosis risk factors (i.e. hypertension, diabetes, hypercholesterolemia, obesity). RESULTS: The results suggest that subjects with histologically proven NAFLD have a reduced cerebral perfusion (CBFr) confined to limited brain areas, i...
