Filter by:Background: People with Williams Syndrome (WS) and supravalvular aortic stenosis (SVAS) have less elasticity in their blood vessels. This is called blood vessel stiffness. Blood vessels may have focal narrowings called stenoses or may just be globally more narrow. Objectives: Researchers want to see how blood vessel differences in people with Williams Syndrome and supravalvular aortic stenosis affect organs in the body including the heart, gut, kidneys, and brain. Eligibility: People ages 3-85 who have WS or SVAS Healthy volunteers ages 3-85 Design: - Participants will have yearly visits for up to 10 years. All participants will be offered the same tests. - Participants will give consent for the study team to review their medical records. If the participant is a child or an adult with WS, a parent or guardian will give the consent. - Participants will visit the NIH where they will have a physical exam and medical history. Based on their health history, participants will undergo a series of imaging tests and measures of blood vessel function over the course of 2-4 days. Tests of cognitive abilites will also be performed. Blood will be drawn and an IV may be placed for specific tests.
The purpose of this project is to build capacity for quality improvement (QI) in small primary care practices across Washington, Oregon and Idaho by improving risk factors for heart attacks such as blood pressure, cholesterol and smoking. The Northwest Coalition for Primary Care Practice Support will assist practices by providing them with a QI coach, creating group learning opportunities, and conducting educational outreach activities. An innovative study design will be used to determine what levels and types of support are most helpful and effective.
The primary goal of proposed investigation is to study the impact of oral glutamine supplementation on muscle mitochondrial and endothelial cell function measured mitochondrial energetics and vascular function using 31P magnetic resonance spectroscopy and optical spectroscopy (MRS/OS) among persons with moderate-severe CKD. The secondary objective is to describe the impact of oral glutamine supplementation on mitochondrial metabolic profile as well as inflammatory and oxidative stress biomarkers among persons with chronic kidney disease.
The purpose of this study is to explore how the End Tidal Carbon Dioxide monitoring via nasal cannula (ETCO2-NC) device may allow for earlier detection of respiratory complications. This device will detect the amount of carbon dioxide exhaled with each breath and may better predict high levels of this than traditional monitoring. This may reduce the number and severity of respiratory issues. A convenience sample of 60 participants either scheduled for continuous flow left ventricular assist device (CF-LVAD) implant or who have been readmitted to an ICU with a CF-LVAD will be recruited and randomized to usual care or usual care plus ETCO2-NC throughout their stay in the ICU.
The purpose of this study is to demonstrate that Spirulina maxima intake and a dosed physical activity program will decrease, both independently and synergistically, cardiovascular risks (Dyslipidemias and oxidative stress) in overweight and obese subjects.
The purpose of this prospective randomized controlled trial (RCT) is to evaluate the feasibility and usability of a commercial pedometer and web application in a case-managed home-based Cardiovascular disease prevention and rehabilitation program for French-speaking Canadians.
Community Paramedicine @Home (CP@Home) is a novel community paramedicine health assessment program for high users of Emergency Medical Services (EMS). Individuals who have been identified as active callers to EMS, individuals who have called EMS for lift-assists, and direct paramedic referrals are referred into the community paramedicine home visit program. The program will focus on in-home chronic disease management, community health service connections, and EMS usage education. Aside from chronic disease management, aspects of the program include health-related quality of life, social isolation and other social determinants of health. Participants in the program will have up to 3 one-on-one home visits from a community paramedic to ultimately reduce repeat EMS calls and improve their overall health.
The overall objective of the proposed cluster randomized trial is to test whether implementation of protocol-based integrated care will improve CVD risk factors (glycated hemoglobin [HbA1C], systolic blood pressure [SBP], and LDL-cholesterol) over 18 months and reduce major CVD events (non-fatal stroke, non-fatal myocardial infarction, hospitalized heart failure, and CVD mortality) over 3 years among patients with type 2 diabetes and additional CVD risk factors or clinical CVD compared to usual team-based care in community clinics in Xiamen, China.
The overall goal of this project is to test the hypothesis that long-term, sustained sleep restriction (SR), in women, will lead to increased cardio-metabolic risk. This will be characterized by increases in visceral adiposity, unhealthy lifestyle behaviors (poor dietary quality and low physical activity) and cardio-metabolic risk factors (blood pressure, glucose intolerance) relative to habitual sleep (HS). The investigators expect these changes to be worse in pre- compared to post-menopausal women.
The aortic valve is located between the left ventricle and the aorta. Patients with symptomatic, severe aortic valve stenosis conventionally have it surgically replaced requiring direct access to the heart through the chest. Transcatheter aortic valve replacement (TAVR) is now a well-established alternative for treating severe aortic valve stenosis. Both types of intervention improve prognosis and alleviate symptoms. The optimal choice of blood thinning therapy after TAVR is unknown. It has been reported that leaflet thrombosis with reduced leaflet motion can occur and this phenomenon has been suggested to be potentially related with neurological events. In addition, the occurence of this phenomenon can be reduced with anticoagulation blood thinning therapy. The purpose of this study is to evaluate if anticoagulation compared to the usual double platelet inhibitor therapy after TAVR can reduce the risk of leaflet thrombosis.
