The Re-Prosper HF Study
Heart FailureHeart failure with reduced ejection fraction (HFrEF) is a common cause for admission within the Veterans Affairs (VA) Health Care System. It is associated with severe impairment of physical and mental health status and carries a high risk of mortality. Even though significant progress has been made in understanding the disease process, currently, its management and treatment is limited. The investigators have discovered that a commonly used drug for the treatment of gout can be repurposed for the treatment of HFrEF. The objective of this study is the treatment of outpatient Veterans with HFrEF with probenecid to improve heart and health function. Specifically, the investigators are testing whether oral probenecid administered orally twice per day for 180 days improves heart function as measured via ultrasound of the heart (aim 1); improves exercise capacity (aim 2); and improves self-report heart failure specific health status as measured via questionnaires (aim 3).

Advanced Heart FailureThe objective of this clinical investigation is to evaluate the efficacy and the safety of the Carmat Total Artificial Heart for the treatment of refractory advanced heart failure in transplant eligible patients.
Patient SELF-management With HemodynamIc Monitoring: Virtual Heart Failure Clinic and Outcomes
Chronic Heart FailureTo demonstrate that a virtual Heart Failure Clinic (HFC) based on patient self-management using Pulmonary Artery Pressure (PAP) monitoring is superior to usual care of HFC, leads to decreased: hospital admissions for heart failure (HF), emergency department consultation and/or unplanned intravenous heart failure therapy and cardiovascular death, compared to a regular HFC, has low device-related complications and is cost-effective, in New York Heart Association (NYHA) class III and II (requiring diuretics) patients.

Metformin for Older Patients With Heart Failure With Preserved Ejection Fraction
Heart Failure With Preserved Ejection FractionMet-PEF will be a randomized, double-blind, placebo-controlled trial to examine the effects of 20 weeks of 1500 mg/day of metformin on physical function, quality of life (QOL), microbiome diversity, leaky gut, and systemic inflammation in patients with 80 older patients with heart failure with preserved ejection fraction (HFpEF).
Heart Rate Regularization in Atrial Fibrilation and Heart Failure
Heart FailureAtrial FibrillationThe PACE-FIB trial is a multicentre, randomised, open-label clinical trial. Patients older than 18 years, with permanent AF, LVEF>40%, average resting heart rate ≤ 110 beats per minute (bpm), at least one hospitalisation due to HF in the previous year and basal NT-proBNP level>900 pg/ml will be randomised to either CSP and subsequent AV node ablation (intervention group) vs. pharmacologic rate control optimised according to clinical practice guidelines. The impact of both strategies on a composite primary endpoint of all-cause mortality, HF hospitalisation and worsening HF will be evaluated during a 36-month follow-up.

A Mechanistic Exploratory Study of AF-induced Cardiac Dysfunction and Symptoms
Atrial FibrillationHeart FailureAlthough the heart rhythm disorder Atrial Fibrillation (AF) affects 2% of the population, the impact it has on an effected individual can be highly variable. Some people are asymptomatic whilst others can experience debilitating symptoms or heart failure (HF)- weakness of the heart muscle. The reason why this variability exists in unknown and how AF actually drives HF is unclear. HF can also be caused by many other reasons and it can be difficult to identify those patients with HF caused by AF versus patients with AF but their HF is due to a different reason. This is important as it would help us to identify those patients most likely to improve their heart function after the treatment of AF and thus gain more from invasive treatments like AF catheter ablation; which is effective at restoring normal heart rhythm but has some risks attached. The investigators suspect the characteristics of the AF, such as how irregularly it makes the heartbeat, can be used to predict who will respond better. Studies of heart cells in the lab as well as animal models have suggested this characteristic may be the cause of AF-induced heart muscle weakness and reduce cardiac output, making it a potential predictor that can be measured. Other potential predictors will be measured during pre-procedural scans and tests too. The investigators will also explore whether there are predictors of which patients gain the most symptomatic benefit and gain insight into why some people develop symptoms of AF, whereas others do not. By studying the structural and functional sequelae of catheter ablation in patients with HF the investigators hope to better understand the relationship between the two diseases.
Efficacy of an m-Health Cardiac Rehabilitation Program in Heart Failure With Preserved Ejection...
Heart Failure With Preserved Ejection FractionHeart failure (HF) portends substantial morbidity, mortality, and health care costs in the United States and the prevalence of heart failure with preserved ejection fraction (HFpEF) relative to HF with reduced ejection fraction (HFrEF) has been increasing. HFpEF is associated with a high morbidity and mortality burden and is projected to be the predominant subtype of HF in the near future. While multiple therapies have proven efficacious for patients with HFrEF, no pharmacological agents have demonstrably been shown to improve outcomes in HFpEF, highlighting the need for novel approaches to HFpEF treatment. Exercise intolerance (EI) is the cardinal symptom of HFpEF, which manifests as dyspnea and fatigue. EI leads to functional deconditioning and reduced quality of life (QOL), both of which elevate risk of death and hospitalization in patients with HFpEF. Supervised exercised training is associated with improvements in exercise capacity and QOL in adults with HFpEF. However, supervised exercise has not been widely utilized for the treatment of HFpEF due to logistical and fiscal barriers. Home-based exercise using an m-Health platform is an alternative to supervised exercise that can deliver clinician prescribed exercise interventions and wellness education though monitoring and care coordination. The goal of this study is to evaluate the feasibility and efficacy of a patient specific progressive home-based cardiac rehabilitation program leveraging the technology of the m-Health program in improving functional status, exercise capacity, and QOL in patients with HFpEF.
