Filter by:The overarching goal of this study is to mimic a night shift work like schedule and characterize circadian variation in Pulse Wave Velocity (PWV), a measure of arterial stiffness, and determine the impact of acute loss of sleep like that experienced by shift workers on PWV.
The primary goal of this intervention is to determine the efficacy of acute mitochondrial-specific antioxidants to improve vascular endothelial function in middle-aged and older (≥45 y) adults who do no perform regular aerobic exercise. In a double-blind, randomized, placebo-controlled crossover design participants with receive both MitoQ and placebo arm of the study. Primary endpoints will include vascular endothelial function assessed by brachial artery flow-mediated dilation and cardiac function assessed via pulse wave analysis. Secondary endpoints will include measures of aortic stiffness assessed by carotid-femoral pulse wave velocity and carotid artery stiffness (e.g. β-stiffness) and elasticity (carotid compliance, distensibility, and Youngs elastic modulus) from ultrasonography.
Studies were found that a significant relationship between the severe periodontitis and increased CAVI values. While the exact mechanisms linking periodontitis, type 2 diabetes, and cardiovascular disease are not yet fully understood, it is clear that these diseases are interconnected. There are limited data in the literature evaluating the risk of atherosclerosis in diabetic individuals with periodontal disease. In our survey, we hypothesised that severe periodontitis may be a risk factor for the development of subclinical atherosclerosis among people with type 2 diabetes. Thus, we aimed to investigate the potential risk of subclinical atherosclerosis by using a new surrogate marker CAVI in severe periodontitis patients with short-term diabetes.
The aim of study is impact of additional treatment with new antidiabetic drugs (semaglutide or empagliflozine) compared to control group in T1DM patients - impact on endothelial function measured by FMD and FPF, arterial stiffness - measured by PWV, inflammatory biomarkers, markers of oxidative stress and endothelial progenitor cells (CD 34+/VDRL2, CD 133+/VDRL2) and correlation with glucovariability or time in range, measured with CGM system.
The ICOPER study aims to analyze the structure, vascular function, vascular aging and determining factors in 300 adults diagnosed with Persistent Covid in the field of Primary Health Care.
This is a single site, single-blinded, controlled randomized crossover clinical trial designed to compare the effects of black beans or whole grains or white rice at breakfast on postprandial vascular responses in males and females with arterial stiffness (n=10). Eligible participants will be asked to attend 3 in-person visits for comparative testing of black beans versus whole grains versus white rice.
The primary goal of the study is to compare different methods for pulse wave measurement and analysis which are cuffless and contactless. The novel measurement tools will be compared to cuff-based reference methods.
The study will show the influence of inflammatory bowel disease on the risk of development of atherosclerosis
Obesity and metabolic dysfunction-associated fatty liver disease (MAFLD) accelerate the appearance of arterial stiffness due to inflammatory and oxidative stress mechanisms producing increased vascular tone and increasing the risk of cardiovascular disease. This arterial stiffness can be measured through pulse wave velocity (PWV). Obesity and MAFLD have multifactorial components, high fructose diet and sedentary lifestyle are causing the onset of these diseases earlier in life such as in adolescence. L-citrulline, a non-protein amino acid, has shown positive effects on improving nitric oxide synthesis which improves endothelial function, as well as results on the metabolic profile in MAFLD. High intensity interval training (HIIT) has also shown benefits on endothelial function improving the metabolic profile of people with obesity and MAFLD with the advantage of decreasing the time required to perform the physical activity. A clinical study will be conducted with 45 adolescents (15-19 years old) with MAFLD and the participants will be divided into 3 groups to perform HIIT and supplement with citrulline or placebo for 12 weeks.
The purpose of this study is to investigate the acute effects of autoregulated (AR) and non-autoregulated (NAR) blood flow restriction (BFR) bicep curls on indices of arterial stiffness. We are attempting to differentiate physiological changes with AR and NAR bicep curl exercise. Twenty adults aged 18-40 years old will undergo three treatment sessions (control (no BFR), AR BFR and NAR BFR) in a randomized order separated by one week. A familiarization session will also occur one week before starting the treatment period. Each subject will undergo a series of tests including anthropometry, ultrasonography of the carotid artery, applanation tonometry, ultrasonography of the vastus lateralis, blood pressure acquisition, body composition, and maximal strength assessments (1RM). After a familiarization session with the BFR device, subjects will perform arm curls during the three treatment sessions with 4 sets to failure with a 2 seconds concentric and 2 seconds eccentric cadence, at 20% 1RM using 60% of the supine limb occlusion pressure (LOP) with 1-minute rest intervals. Assessments will be performed immediately before and after the exercise bout during each treatment session. Two-way ANOVAs will be used to examine the effects of treatment and the treatment-order interaction on pulse wave velocity, beta-stiffness index, and augmentation index.
