Filter by:In an unbiased metabolomics approach with subsequent pathway analyses, the current study seeks to examine the effect of Liraglutide treatment on the metabolic signature in treated patients as well as the effect of Liraglutide on various echocardiographic parameters of cardiac function and rhythm profile, thus paving the way for future research to explain the effects of Liraglutide on cardiovascular mortality and overall mortality in treated patients.
DEFINIT-P is a prospective pilot study of frailty in cardiac device recipients, comprised of a registry and randomized control trial. The RCT is a supervised exercise program and nutritional supplement intervention for pre-frail and frail cardiac device participants. The registry will be used to describe all cardiac device recipients, regardless of frailty status.
Longterm oral anticoagulation with very low dose rivaroxaban (2.5mg bid) in combination with aspirin has been shown superior over standard aspirin monotherapy in patients with stable coronary artery disease (CAD) in the COMPASS trial. To date, there are no data comparing these - antithrombotic strategies and to provide insights about mechanistic effects of very low dose rivaroxaban on top of aspirin for longterm treatment. Thus, the goal of the planned pilot study will be to identify effects of rivaroxaban on platelet function, platelet-mediated vascular inflammation and particularly, platelet-mediated thrombin generation as well as the underlying mechanisms and to reveal differences in mechanistic effects during longterm treatment with combined novel antiplatelet/anticoagulant strategies. This study is planned as descriptive study.
The proposal contained herein seeks to examine the effect of simulated microgravity on important cell-cell interactions that govern vascular health. The interest lies in endothelial cell (EC) and macrophage cell interactions. The investigators are proposing to first understand how microgravity effects the macrophage and EC function or pro-healing capabilities. Next, the study team plans to develop a 3D tissue regeneration model in which macrophages and ECs are co-cultured in a hydrogel matrix. Utilizing this model, the team will assess how microgravity influenced macrophage-EC interactions in 3D. The investigators will assess EC tubule volume (or blood vessel development), macrophage spreading and the interactions with endothelial tubule sprouts. This model will serve as a critical foundation for future grant opportunities as it allows the assessment of tissue regeneration and vascular health in a 3D tissue microenvironment
This study will investigate chronic kidney disease (CKD) and cardiovascular disease (CVD) risk factors in a sample population of Hispanics/Latinos and Caucasians in Yakima county that are rural dwelling. This investigation is intended to provide information on the impact rural geographical location and social determinants of health (SDOH) have on CKD and CVD risk factors.
Health literacy is the ability to access, understand, evaluate and apply information in order to communicate with health professionals and understand health instructions but also, promote, maintain and improve health throughout life. Health literacy (HL) is known as a health determinant. An association has been shown between low HL and poorer health outcomes such as increased number of unscheduled hospitalisation or emergency visits, low medication adherence and poor health status. These have been particularly demonstrated with cardiovascular diseases, which combine risk factors (emergency hospitalization, reduction in the length of hospital stays, and complex secondary preventive drug treatments). Despite large scientific international literature about HL and health outcomes, no information is available in France on the prevalence of low HL level among patients managed for neuro-cardio-vascular diseases. It has been shown in other countries that healthcare professionals overestimate the HL level of their patients and do not adapt information to the HL level. Therefore, patients with low HL do not understand and/or are not able to use properly the information they receive. Having a better knowledge of HL level and characteristics in these patients is necessary to develop tools for helping healthcare professionals to identify patients with low HL level and to realize the role of HL as a determinant of health. It will also provide more precise information on the difficulties or needs of patients with different levels of health literacy.
The goal of this study is to determine whether the Bay Labs artificial intelligence (AI) system can be used by minimally trained operators to obtain diagnostic quality echocardiographic images.
Title: Effects of oral antioxidant cocktail on vascular function and muscle function in cardiovascular disease patients Cardiovascular disease (CVD) generally refers to various conditions involving narrowed or blocked dysfunctional blood vessels that often lead to heart attack or stroke. One of the main contributors to blood vessel dysfunction is damage to the vascular endothelium. This often results from the accumulation of oxidative stress (OS) and inflammation due to a decrease in blood flow and oxygen transport to the body's organs and skeletal muscle. The body's natural antioxidant defense system cannot keep up with the high level of OS clearance necessary to maintain proper vascular homeostasis. Previous research has addressed the use of single antioxidants (e.g. vitamin E, beta-carotene, ascorbic acid) in CVD patients, but the use of a combination of antioxidants has yet to be examined. Therefore, the purpose of this study is to examine the effects of acute oral antioxidant cocktail administration (containing vitamin C, E, and alpha-lipoic acid) on oxidative stress, vascular function, autonomic function (heart rate variability), leg blood flow, leg muscle tissue oxygenation, and walking capacity in CVD patients. This is a parallel study design that will assess the effects of oral antioxidant cocktail administration on CVD patients ages 50-85. Subjects will be required to visit the lab 1 time. This visit will consist of 1) obtaining informed consent and questions, 2) baseline blood sampling and baseline measurements of endothelial function, arterial stiffness, autonomic function (heart rate variability), leg blood flow, leg muscle oxygenation, and a walking test, 3) first dose oral antioxidant cocktail administration followed by a 2-hour break, 4) second dose oral antioxidant cocktail 30 minutes after the first dose, 5) post-consumption blood sampling and measurements of endothelial function, arterial stiffness, autonomic function (heart rate variability), leg blood flow, leg muscle oxygenation, and a walking test.
This study will assess the effect of treatment for hepatitis C virus (HCV) on cardiovascular disease risk. The study will enroll men and women who are infected with HCV and have underlying metabolic disease. All participants will receive a 12-week course of an HCV treatment (elbasvir/grazoprevir). Cardiovascular disease risk will be evaluated at baseline, week 4 on treatment, 12 weeks post-treatment, and 52 weeks post-treatment through noninvasive measurements of endothelial function, insulin resistance, liver fibrosis and steatosis, and circulating blood biomarkers.
This randomized, controlled clinical pilot trial will evaluate the effects associated with in-office use of closed-loop, acoustic stimulation neurotechnology (High-resolution, relational, resonance-based, electroencephalic mirroring; HIRREM), compared with acoustic stimulation not linked to brainwaves (ambient nature sounds), for participants with pre-hypertension. Data collection will occur at baseline, and at intervals after completion of the intervention. Outcomes include blood pressure, measures of autonomic cardiovascular regulation, behavioral symptom outcomes, quality of life, alcohol use, and functional performance measures. The primary outcome will be change in blood pressure from baseline to 4-6 weeks after intervention.
