Filter by:The glycocalyx serves as the interface between flowing blood and endothelial cells, the single cell layer that lines blood vessels, and is crucial for normal blood vessel function. Specifically, the glycocalyx protects endothelial cells from oxidative stress and inflammation and enables blood vessel dilation, which is largely dependent on the bioavailability of the vasodilatory molecule nitric oxide. Importantly, glycocalyx thickness decreases with age and is predictive of major adverse cardiovascular events in older adults free of cardiovascular disease. Therefore, interventions aimed at restoring glycocalyx thickness in older adults are desperately needed. Endocalyx Pro is a commercially available glycocalyx precursor supplement, manufactured by Microvascular Health Solutions, designed to 1) repair a damaged glycocalyx, 2) protect against damage to the glycocalyx, and 3) synthesize new glycocalyx components, and has been used to increase glycocalyx thickness in humans. However, no study has tested if glycocalyx thickness restores glycocalyx thickness in older adults and improves blood vessel function. Thus, the purpose of this investigation is to determine if 12-weeks of Endocalyx Pro supplementation alters glycocalyx thickness and blood vessel function in older adults. The investigators will use a camera placed under the tongue to determine glycocalyx thickness. The investigators will measure blood vessel function by measuring brachial artery dilation with ultrasound and arterial stiffness using pressure probes placed on the carotid and femoral artery.
Home-based exercise interventions were the only alternatives to attenuate physical deconditioning and ameliorate traditional and emergent cardiovascular risk factors progression during the COVID-19 outbreak. Benefits in physical and psychological health have only been reported in adults without intellectual and developmental disability (IDD). The purpose of this study is to compare home vs gym-based delivery exercise modes of two 8-week supervised aerobic training regimes on cardiorespiratory fitness and arterial structure and stiffness in adults with IDD. It is hypothesized that home- and gym- based exercise delivery modes will be equally effective in improving cardiorespiratory fitness and overall arterial heath, although in an intensity dependent manner. A secondary analysis examining changes in blood pressure and body composition will be performed.
The aim of this study is to assess the effect of interval hypoxy-hyperoxic training (IHHT) on the arterial stiffness and elasticity of the liver tissue in patients with metabolic syndrome and on other components of the metabolic syndrome, and the possibility of their reversible recovery after training.
This is a single-center observational study on adolescents to determine predictors of the early steps of the formation of atherosclerosis and to quantify their influence on Intima-Media-Thickness of the carotid artery and the aorta and on the Pulse-Wave Velocity. A long-term follow-up by means of record linkage is furthermore planned to evaluate the effect of early atherosclerosis and the cardiovascular risk profile on future morbidity with a special focus cardio- and cerebrovascular events.
The investigators aim to investigate the factors affecting cardiorespiratory fitness in individuals with systemic hypertension.
The goal of this study is to pilot test a 12-week behavioral intervention among perimenopausal Latinas (age 40-55 years) that integrates evidence-based education with physical activity, stress management, and coping skills training to: 1) reduce cardiovascular disease (CVD) risk factors and arterial stiffness; 2) improve nutrition, physical activity, and sleep behaviors; and 3) improve stress management, coping strategies, and self-efficacy. This study will recruit participants from two community groups: one group will be randomly assigned to complete the intervention; the other will be a wait-list control.
The investigators will aim to determine the association of mood disorders (MDO) with preclinical and clinical cardiovascular (CVD) risk factors among children. The investigators will also aim to identify traditional and non traditional predictors of CVD risk among children with MDO.
Blueberries are rich in the content of a variety of biologically active chemicals that contribute to their health properties. The consumption of blueberries has beneficial effects on vascular function and brain health and function. Blueberries are present in human diet in a number of forms, but the investigator do not know which form is best for health and why people respond differently to eating blueberries. The aim of the present study is to assess the effects of 1 week's supplementation of whole blueberries or freeze-dried blueberry powder or encapsulated blueberry components on vascular function and brain health and function. Investigators will then categorise participants as those who have large effects of the intervention (responders) and those that don't show much effect at all (non-responders). Then the investigators will look into the role that genes play in this response and determine if metabolism is similar in these groups of participants. Any changes in participants' brain health and vascular function will be linked to these metabolic and genomic pathways, and this will help the investigators to further understand how blueberry consumption can benefit human health.
The investigators aim to determine the association of dietary intake on cardiovascular disease risk factors among children with overweight and obesity who are being evaluated for elevated blood pressure. The investigators will also investigate for predictors of vascular function and determine if predictors vary by level of sodium intake.
Title of the study: Target weight correction and vascular stiffness in hemodialysis patients Study design: Randomized clinical trial in the study centre at two locations Applied medical device: 1. Body Composition Monitor' (BCM, Fresenius) to measure fluid volume overload. 2. Arteriograph 24 (Tensiomed, Budapest, Hungry) to assess vascular stiffness before, during and after the intervention. Study hypothesis: A protocolized adjustment of target weight guided by bio-impedance spectroscopy will improve fluid status, systolic and diastolic blood pressure, and reduce the arterial wall stiffness without increasing the prevalence of intradialytic hypotension. Aim of the study: 1. To demonstrate improvement in fluid status by a target weight correction protocol which applies BCM measurements. 2. To demonstrate that better fluid volume control is associated with a) improvement in vascular health as assessed by pulse wave velocity and augmentation index and b) reduction in antihypertensive medications use. 3. To show that this approach does not lead to more episodes with intradialytic hypotension. The number of patients: 70 patients
