WISE CVD - Continuation (WISE HFpEF)

The Women's Ischemia Study Evaluation (WISE), a cohort study of over 1000 women, has made many contributions to the understanding of cardiovascular disease. A milestone acknowledged in the 2011 AHA Herrick Lecture is the role of Coronary Microvascular Dysfunction (CMD) in women with symptoms/signs of ischemia without obstructive coronary artery disease (CAD). While in 1996, CMD was considered "an imaging artifact", in 2013, it is a widely accepted as a pathophysiologic process requiring systematic cohesive scientific pursuit. CMD is prevalent, associated with adverse clinical outcomes, poor quality of life and healthcare costs rivaling obstructive CAD. There are 2-3 million US women with CMD, and 100,000 new cases projected annually placing CMD prevalence, morbidity and costs higher than all female reproductive cancers combined. Among women with ischemia, preserved ejection fraction and no obstructive CAD, it has been observed that there are relatively more new onset heart failure (HF) hospitalizations than nonfatal myocardial infarction (MI). It has been hypothesized that CMD contributes to left ventricular (LV) diastolic dysfunction and subsequent heart failure with preserved ejection fraction (HFpEF). Preliminary data further suggests that left ventricular diastolic dysfunction is linked to CMD via a mechanism of augmentation and/or perpetuation by cardiomyocyte fat accumulation. HFpEF is prevalent in women and older men, but poorly understood. Mechanistic understanding is critical to HFpEF intervention and guideline development. The study hypotheses are as follows: 1. Risk factor conditions (hypertension, dyslipidemia, dysglycemia, loss of estrogen) promote an inflammatory and pro-oxidative state making the microvasculature vulnerable; 2. Vulnerable coronary microvasculature becomes dysregulated (sympathetic nervous system activation, endothelial dysfunction, changes in vascular smooth muscle activation, spasm) causing repeated episodes of transient ischemia; 3. Repeated ischemia-reperfusion episodes facilitate preconditioning with preservation of cardiomyocyte contractile and microvascular function against ischemic injury; 4. Ischemia-reperfusion and preconditioning lead to cardiomyocyte fat accumulation and relaxation impairment resulting in diastolic dysfunction and heart failure with preserved ejection fraction (HFpEF).

The Role of Anifrolumab in Improving Markers of Vascular Risk in Patients With Systemic Lupus Erythematosus (SLE) - IFN-CVD

Background: People with systemic lupus erythematosus (SLE) are at risk of developing complications in their blood vessels. This can increase the risk of heart attacks or stroke. No medications have been effective at reducing this risk in people with lupus. Objective: To test whether a drug (anifrolumab) can improve blood vessel function and reduce blood vessel inflammation in people with SLE. Eligibility: People aged 18 to 80 years with SLE. Design: Participants will undergo screening. They will have a physical exam. They will have blood and urine tests. They will have a test of their heart function and a chest X-ray. They will answer questions about their SLE symptoms. Participants will visit the clinic 9 times in 8 months. After screening, visits will be 4 weeks apart. Each visit may take up to 4 hours. Participants will receive infusions from a tube attached to a needle inserted into a vein in the arm (IV). Some will receive anifrolumab. Others will receive a placebo treatment. They will not know which one they are getting. At some visits they will have additional tests: CAVI (cardio-ankle vascular index) tests blood vessel function. Participants will lie still for 20 minutes. Small electrodes will be placed on both wrists with stickers. A microphone will be placed on their chest. Blood pressure cuffs will be wrapped around their ankles and arms. FDG-PET/CT is an imaging procedure. Participants will receive a substance through an IV line. They will lie on a table for 110 minutes while a machine captures images of their body.

CHIP in Health and Disease

Clonal hematopoiesis (CH), including clonal hematopoiesis of indeterminate potential (CHIP), is an age-associated condition characterized by the expansion of hematopoietic stem and progenitor cell clones carrying acquired somatic mutations. Although CH is associated with an increased risk of hematologic malignancies, its greater public health impact derives from its strong association with cardiovascular diseases, including coronary artery disease and stroke. Emerging evidence suggests that CH-associated mutations promote chronic inflammatory signaling in myeloid immune cells, thereby contributing to atherosclerosis and adverse cardiovascular remodeling. This observational translational study aims to characterize the biological spectrum of clonal hematopoiesis across different stages of disease risk and manifestation. Using state-of-the-art single-cell and multi-omics approaches, the study will compare inflammatory pathways, immune cell states, and mutation-associated molecular programs among healthy individuals without CH, individuals with high-risk CH, and patients with CH-associated hematologic or cardiovascular disease. The ultimate goal is to identify shared and disease-specific mechanisms linking clonal hematopoiesis to adverse clinical outcomes and to generate insights for future preventive, anti-clonal, and anti-inflammatory therapeutic strategies.

A Novel Digital Tool Physicians Can Use to Prescribe Exercise to Patients With Cardiovascular Disease Risk Factors

The investigators will conduct a feasibility and pilot efficacy randomized controlled trial to test the usability and user satisfaction of an evidence-based digital health tool the investigators developed for physicians to use to Prioritize Personalize Prescribe EXercise (P3-EX) to patients with cardiovascular disease (CVD) risk factors. The investigators will recruit 24 physicians from two local hospitals in CT, USA. Physicians will recruit two patients each (N=48) having CVD risk factors. Physicians will deliver a P3-EX exercise prescription (ExRx) to one of their patients (n=24) and the American College of Sports Medicine Physical Activity Vital Sign (ACSM-PAVS) ExRx to the other (n=24) in a random sequence crossover design. Physicians and patients will rate the feasibility and acceptability of each method using validated questionnaires. Patients will perform their prescribed ExRx for 12 weeks and complete a self-report exercise diary to monitor exercise adherence with virtual oversight from University of Connecticut (UConn) Graduate Research Assistants. Before and after the exercise intervention, the investigators will measure patient CVD risk factors and physical activity (PA) levels via accelerometry. The primary aim is to evaluate the feasibility and acceptability of P3-EX for physicians to use to prescribe exercise to patients with CVD risk factors, and the secondary aim is to explore the preliminary efficacy of P3-EX to improve patient CVD risk factors, PA levels, and exercise adherence. The investigators hypothesize P3-EX will be feasible for physicians to use to prescribe customized exercise routines for patients with CVD risk factors, and physicians and patients will be satisfied with P3-EX.

Heart Health Study in Washington D.C. to Develop a Community-Based Behavioral Weight Loss Intervention

Background: \- Past studies suggest that the best way to improve heart health in the Black community is through community-based programs. Researchers will partner with DC community leaders. They will collect information about the health and health needs of people in mostly Black churches in DC. They will study things that affect heart health, like diabetes, blood pressure, cholesterol, and weight. They will also study how technology can keep track of activities and health. The information will show the health needs of church-based communities or faith-based organizations. Objectives: \- The primary objective of this study is to estimate the percentage of the population that meet ideal, intermediate, and poor criteria for each of the cardiovascular health factors (BMI, physical activity, dietary intake, blood pressure, total cholesterol, fasting plasma glucose, and cigarette smoking) in churches or faith-based organizations in the DMV area. This data will inform the design and implementation of a behavioral weight-loss intervention within the faith-based community immediately following this study. The secondary objectives are to: 1) evaluate usage of handheld devices for objectively measuring physical activity and dietary intake; 2) evaluate usage of web-based technology for monitoring cardiovascular health markers, including dietary intake; 3) examine referral methods for untreated hypertension, diabetes, and hypercholesterolemia; 4) compare lifestyle behaviors across levels of psychosocial factors, cultural norms, and neighborhood environment factors; and 5) formalize a community advisory board involved in the implementation of the health screening and needs assessment program and a future behavioral weight-loss intervention. Eligibility: \- Adults ages 19 to 85 who attend one of the study churches. Design: * Participants will visit their church for a 4-hour health exam. They will have their blood pressure and body measurements taken. They will have a drop of blood taken from their finger with a small needle. This blood will be tested for blood sugar and cholesterol. Participants will be given the results of these tests. * Participants will answer questions about their health. * All participants will be given an activity monitor to wear for 1 month. The activity monitor is worn around the wrist. Some participants will also receive an activity monitor that is worn around the waist. Participants will be given instructions on how to wear the activity monitors and follow the results on a website. * At the end of 1 month, participants will return one device (they can keep the other). They may receive a gift card for completing the study.

Fish Oil and HDL Function in Patients on Maintenance Hemodialysis

Patients who receive maintenance hemodialysis have a very high risk of cardiovascular disease, and standard cholesterol-lowering treatments such as statins have not been shown to reduce cardiovascular events in this group. A recent clinical trial (PISCES) found that high-dose omega-3 fatty acids (fish oil) reduced cardiovascular events in hemodialysis patients, but the reason for this benefit is not understood. One possible explanation is that, in kidney failure, high-density lipoprotein (HDL) no longer works normally. This study investigates whether omega-3 fatty acid supplementation improves the function of HDL in people on maintenance hemodialysis. Forty adults on maintenance hemodialysis will take part. Each participant receives fish oil (4 g per day) for 8 weeks and also has an 8-week period without supplementation; participants are randomly assigned to the order of these two periods (crossover design), for a total of 16 weeks each. The main measure is cholesterol efflux capacity, a laboratory test of how well HDL removes cholesterol from cells. The study also examines other markers of HDL quality. This is an exploratory, mechanistic study. Its aim is to determine whether omega-3 fatty acids change HDL function and to inform the design of larger future trials.

Clinical and Molecular Characteristics of Primary Aldosteronism in Blacks

Background: The adrenal gland makes the hormone aldosterone. This helps regulate blood pressure. An adrenal gland tumor that makes too much aldosterone can cause high blood pressure and low potassium. The cause of these tumors is unknown, but sometimes they are inherited. Objective: To study the genes that may cause primary aldosteronism in Black individuals. Eligibility: People ages 18-70 who: Are Black, African American, or of Caribbean descent And have difficult to control blood pressure or primary aldosteronism Relatives of people with primary aldosteronism Design: Participants who are relatives of people with primary aldosteronism will have only 1 visit, with medical history and blood tests. Participants with primary aldosteronism or difficult to control blood pressure (suspected to possibly have primary aldosteronism) will be screened with a 1-2 hour visit. If they qualify, they will return for a hospital stay for 7-10 days. Tests may include: Medical history Physical exam Blood tests: Participants will have a small tube (IV catheter) inserted in a vein in the arm. They may drink a glucose-containing liquid or get a salt solution. If medically indicated, they may have invasive blood tests with a separate consent. Urine tests: Some require a high-salt diet for 3 days. Heart tests Scans: Participants lie in a machine that takes pictures of the body. A dye may be injected through a vein. Small hair sample taken from near the scalp. Kidney ultrasound Bone density scan: Participants lie on a table while a camera passes over the body. If the doctors feel it is medically necessary, they will offer participants treatment depending on their results. These treatments may cure the patient of their disease and may include: 1. Having one adrenal gland removed by the Endocrine surgeon under anesthesia. Patients will have follow-up visits 2-4 weeks after surgery. 2. Taking drugs to block the effects of aldosterone Participants may return about 1 year later to repeat testing....

Technical Development of Cardiovascular Magnetic Resonance Imaging

Background: In the U.S., over 6.5 million people have heart failure. Researchers want to develop new testing methods for cardiovascular problems using magnetic resonance imaging (MRI) to improve the clinical diagnosis and management of people with heart failure. Objective: To develop and test new methods for imaging the heart and blood vessels using MRI. Eligibility: People ages 18 years and older who are having an MRI of their heart or blood vessels. Healthy volunteers are also needed. Design: Participants will be screened with a medical history. Participants will have a physical exam and blood tests. They will have an electrocardiogram (ECG) to measure the heart s electrical activity. Then they will have their scheduled MRI scan. The MRI scanner is a large, hollow tube. Participants will lie on a table that moves in and out of the tube. During the MRI, they may have contrast dye injected through an intravenous line inserted into their arm or hand. ECG may be used to monitor their heartbeat or coordinate pictures with their heartbeat. A flexible belt may be used to monitor their breathing. A finger probe may be used to track their heart rate and/or oxygenation level. Their blood pressure may be measured. Pictures may be taken of their blood vessels, heart, and lungs before, during, and after they get medicine to increase blood flow. They may lie flat and pedal a stress bicycle to increase their heart rate. Participation will last for 5 years. During that time, participants may receive a yearly survey about their health. They may be contacted for an optional follow-up MRI within 2 years of their MRI.

Gauging Outcomes of Total Milk Ingestion on Lipid and gControl

Atherosclerotic cardiovascular disease remains the leading cause of death for adults in the United States. The cardiovascular impact of milk consumption remains a matter of long-standing scientific debate. Current guidelines for Americans recommend three daily servings of fat-free or low-fat (1%) dairy over full-fat options due to concerns that saturated fat may increase cardiovascular risk. Yet, the literature does not consistently support non-fat dairy as superior to high-fat dairy for reducing cardiometabolic risk. Identifying the comparative health benefits of non-fat versus high-fat dairy milk would be immediately applicable to patients who seek cardiovascular care. In this randomized, case-crossover trial, the investigators seek to efficiently assess the association between high-fat versus non-fat dairy milk consumption and insulin resistance. Utilizing the Eureka Platform, participants will be randomized to limit their liquid milk consumption to whole milk followed by skim milk (or vice versa), measuring the effect of milk fat content on glycemic index and lipid profile.

Cardiology Biobank Registry

In the present study, investigators intend to establish a large database of cardiovascular patients. More specifically, investigators will create a database of approximately 12,000 cardiac catheterization and heart failure patients from Emory University Hospital, the Emory Clinic, Emory University Hospital Midtown, Grady Memorial Hospital, Atlanta VA Medical Center, Organized/Planned Community Events in the Atlanta Metropolitan area, held at places of Worship, local Community Centers, shopping Malls, doctor's Offices and Health Clinics and any other miscellaneous locations, e.g. Parks, Leisure centers, Conference centers. Once the data has been collected, investigators will run a variety of statistical analyses to which will help us to learn more about the factors that cause various cardiovascular diseases such as coronary heart disease, angina, heart failure, hypertension, and stroke. The statistical analyses will also help us to understand how these diseases can be treated more effectively. By collecting a large amount of data on a large number of cardiovascular patients, investigators will be able to analyze, with a great deal of precision, those factors that influence the onset, course, and treatment of cardiovascular disease. The results of these precise analyses can then be used to help optimize clinical efforts to prevent and treat cardiovascular disease.

Improving Veteran Referral to Cardiac Rehabilitation

This study will test whether the Veterans Cardiac Rehabilitation Referral Program (VCR2P) improves cardiac rehabilitation participation by studying 816 Veterans across three VA medical centers in Nashville, Dallas, and Gainesville over 12 months. The trial compares referral rates from the 6 months before implementing the program to 6 months after, using a "before and after" design since randomization would be impractical. The study will measure whether the program increases the proportion of eligible Veterans who receive cardiac rehabilitation referrals and whether more Veterans actually attend rehabilitation sessions. Additionally, focus groups with physicians, nurses, and Veterans will identify what helps or hinders the program's success, providing essential insights for expanding this intervention to other VA facilities nationwide if it proves effective.

Measurements Before and After Participation in a Health Intervention Programme in Halsnaes Municipality

Based on the Danish Health Authority's quality standards for municipal prevention services for citizens with chronic diseases, Steno Diabetes Center Copenhagen (SDCC), Halsnaes Municipality, North Zealand Hospital, and others have entered into a cross-sectoral collaboration entitled "Quality Development in Community Healthcare: Steno Tvaers - A Model for Differentiated Health Interventions for Citizens with Diabetes, Chronic Obstructive Pulmonary Disease (COPD), or Cardiovascular Disease sased in Halsnaes Municipality" (hereafter referred to as Steno Tvaers). Based in Halsnaes Municipality, the aim of Steno Tvaers is to adapt and, where relevant, supplement existing healthcare services in the municipality to better meet the needs of and reach all citizens with chronic diseases. The present sub-project "Measurements before and after participation in a health intervention programme in Halsnaes Municipality" (hereafter referred to as the sub-project) is conducted within the framework of Steno Tvaers. The objective of the current sub-project is to assess whether citizens with diabetes, COPD, or cardiovascular disease, who participate in a health intervention programme in Halsnaes Municipality, improve their functional capacity. For citizens with diabetes, the sub-project also aims to assess whether participation in the programme results in improved blood glucose concentration, blood pressure, and medical adherence. The hypothesis of the sub-project is that the organizational changes planned within Steno Tvaers for successful implementation of the quality standards will lead to a resulting health effect at the individual level. It is important to note that the healthcare interventions are existing services, the quality and uptake of which are being enhanced through the Steno Tvaers project, and that this does not involve testing a new intervention. Participation in the project therefore only involves contributing data that are already being collected by the municipality, supplemented by responses to two questionnaires. For citizens with diabetes, this is further supplemented with data on blood glucose (HbA1c), blood pressure, attendance at follow-up visits with general practitioners and in hospital settings, as well as adherence to prescribed medication. Data are collected at the beginning and at the end of a health intervention programme, and at the end of the project, the data will be linked to selected national registers.

Feasibility of The Health Integrated Nutrition and Kidney Wellness Program

Purpose of the Study: This clinical trial will test whether a nutrition and kidney health program can work well for adults with kidney disease. The program was created with help from patients and community partners. Main Questions: How many eligible patients choose to join the program? How many participants finish the full 12-week program? How satisfied are participants with the program? What Participants Will Do: Participants will be assigned to a diet-focused lifestyle education series (THINK-Well Intervention) or enhance usual care. THINK-Well Intervention group will take part in 7 group education sessions over 12 weeks. Sessions will be online and in-person. Topics include eating to promote heart-kidney-and metabolic health, managing long-term health conditions, setting health goals, and sharing experiences with others who have chronic disease. Participants will practice meal preparation through cooking classes and have opportunity to apply lessons on choosing whole foods with food bucks provided. The enhanced usual care group will receive two virtual nutrition education sessions led by a trained educator over 12 weeks. Topics will be similar to standard education provided to people with kidney disease managed by a kidney doctor. Topics will be adapted from established resources from the National Kidney Foundation, American Kidney Fund, and American Heart Association.
