The purpose of this study is to present the importance of work-related cerebrovascular and heart disease from the viewpoint of expenses. Using the insurance benefit paid for the 4,300 cases, this study estimated the burden of insurance benefits spent on work-related cerebrovascular and heart disease. The number of cases with work-related cerebrovascular and heart disease per 100,000 insured wor...
Blood oxygen level-dependent (BOLD) functional magnetic resonance imaging (fMRI) studies of patients with cerebrovascular disease have largely ignored the confounds associated with abnormal cerebral blood flow, vascular reactivity and neurovascular coupling. We studied BOLD fMRI activation and cerebrovascular reactivity in moyamoya disease. To characterize the impact of remote vascular demands ...
BACKGROUND Several studies have demonstrated that atherosclerotic complications are the major cause of morbidity and mortality in end-stage renal disease (ESRD) patients on dialysis. The allele epsilon 4 of apolipoprotein E (ApoE) gene has been associated with an increased risk for ischaemic cerebrovascular disease (ICVD) in general populations in recent preliminary cross-sectional studies. M...
BACKGROUND Cerebrovascular lesions are a frequent finding in the elderly population. However, the impact of these lesions on cognitive performance, the prevalence of vascular dementia, and the pathophysiology behind characteristic in vivo imaging findings are subject to controversy. Moreover, there are no standardised criteria for the neuropathological assessment of cerebrovascular disease or i...
Chronic obstructive pulmonary disease (COPD) is associated with cerebrovascular abnormalities and an overproduction of reactive oxygen species. We hypothesised that COPD patients have oxidant-related cerebrovascular dysfunction. Our main objective was to evaluate cerebrovascular reactivity and its relationship with oxidative stress in females with COPD. We studied eight females with moderate CO...
Vascular risk factors and cerebrovascular disease are common causes of dementia. Shared risk factors for vascular dementia and Alzheimer's disease, as well as frequent coexistence of these pathologies in cognitively impaired older people, suggests convergence of the aetiology, prevention and management of the commonest dementias affecting older people. In light of this understanding, the cognit...
AIMS Cerebrovascular complications are relatively uncommon, but severe adverse events are associated with catheter ablation of atrial fibrillation (AF). This study aimed to investigate the incidence, risk factors, and hospital outcomes of cerebrovascular events complicating AF ablation. METHODS AND RESULTS Cerebrovascular complications occurring during the procedure or hospitalization after A...
OBJECTIVE Cerebral vessels, such as intracerebral perforating arterioles isolated from rat brain, have been widely used as an ex vivo model to study the cerebrovascular function associated with cerebrovascular disorders and the therapeutic effects of various pharmacological agents. These perforating arterioles, however, have demonstrated differences in the vascular architecture and reactivity c...
introduction: evaluation of persistent vertigo in post infarct patients is very important as the management depends on whether the cause is purely of central origin or due to associated vestibular affliction. case report: a patient with left sided dorsolateral medullary syndrome and persistent vestibular symptoms was evaluated. vestibular test battery showed abnormal smooth pursuit, bilateral...
Neonatal seizures have been associated with cerebrovascular endothelial injury and neurological disabilities. In a piglet model, the long-term loss of endothelial regulation of cerebral blood flow coincides with the surge of brain-derived circulating endothelial cells (BCECs) in blood. We hypothesized that BCECs could serve as a noninvasive biomarker of cerebrovascular injury in neonates with s...
