Mechanistic Clinical Trial Comparing the Pharmacokinetics/Pharmacodynamics of Metoprolol in Heart Failure With Reduced Ejection Fraction Patients With Low vs. High Polygenic Score
The purpose of this trial is to better understand how the beta-blocker metoprolol works in people with Heart Failure with Reduced Ejection Fraction (HFrEF) according to participants genetics. Participants will have the beta-blocker (BB) polygenic score calculated from genotype data. The score will be used to stratify the patients in the low and high polygenic score groups in the study. The hypotheses for this trial are: * HFrEF patients with high polygenic score will have weaker cardiovascular responses to metoprolol succinate than HFrEF patients with low polygenic score. * HFrEF patients with high polygenic score have lower steady-state plasma concentrations of metoprolol succinate than HFrEF patients with low polygenic score. * HFrEF patients with high polygenic score require higher metoprolol succinate plasma concentrations to achieve similar cardiovascular effects as those with low polygenic score.

Optimal PharmacoTherapy and Invasive Management of Atrial Fibrillation in Patients With Heart Failure
Atrial Fibrillation (AF) and Heart Failure (HF) are colliding global cardiovascular epidemics, individually impairing quality of life and cardiac performance, as well as increasing the risk of hospitalisation and mortality. When AF and HF co-exist, disease progression accelerates and the adverse outcomes are magnified, leading to incrementally higher morbidity, mortality, and healthcare expenditure. The management of AF is dichotomised into the restoration and maintenance of sinus rhythm ("Rhythm control") or acceptance of AF with control of the ventricular response ("Rate control"). Previous studies suggested that pharmacologic rhythm control and pharmacologic rate control confer similar survival and morbidity outcomes in patients with significant left ventricular dysfunction. Recognising the limitations of pharmacotherapy, more recent studies have examined the utility of catheter ablation procedures designed to restore and maintain sinus rhythm (e.g., catheter-based pulmonary vein isolation). Studies have suggested that catheter ablation procedures may provide sustained improvements in quality of life, decreased hospitalisation and, potentially, improved survival for patients with co-existing AF and HF, when compared to pharmacotherapy. However, significant limitations in these small trials have limited their impact on clinical practice. We propose a randomised controlled trial to definitively answer the question regarding the optimal treatment of AF in patients with heart failure with reduced ejection fraction (HFrEF), specifically aiming to determine if catheter ablation can reduce death, stroke, and heart failure events.

Home-Based Cardiac Rehabilitation for Patients With Heart Failure
The vast majority of individuals with heart failure do not participate in center based cardiac rehabilitation (CBCR). While steps to increase utilization of CBCR are important, many individuals will still not participate for a variety of reasons. This pilot randomized controlled trial is evaluating a home-based cardiac rehabilitation (HBCR) intervention delivered using a custom app and digital tools in patients with heart failure. After a brief roll-in period, participants are randomized to one of two groups: (1) control or (2) HBCR mobile health intervention. The intervention targets key health behaviors and includes traditional cardiac rehabilitation components. The study will assess the effect of the intervention on physical activity, quality of life, clinical events, and other outcomes.

Midodrine in Heart Failure With Reduced Ejection Fraction With Hypotension
The evidence-based pharmacologic treatments available for patients with heart failure with reduced ejection fraction (HFrEF) has been established over the last few decades of cardiovascular research. These treatments, termed Foundational Guideline-Directed-Medical Therapies (GDMT), prolong patient life, improve patient-reported symptoms, and reduce hospitalizations for heart failure. A direct effect of most medication classes encompassed within GDMT is the reduction in blood pressure due to their mechanisms of action. In addition, as patients with HFrEF become more advanced in their disease, a significant proportion develop hypotension related to pump failure and autonomic dysfunction, amongst other possible mechanisms. As a result, a significant proportion of HFrEF patients are not optimized on GDMT with hypotension as their limiting barrier that would otherwise have served to improve their heart function, heart failure symptoms, and mortality. Currently, there does not exist any evidence-based strategies to address the problem of hypotension in HFrEF patients who are not optimized on GDMT. Midodrine is an alpha-adrenergic agonist (α1-AR) that exerts its effects on peripheral venous and arteriolar vasculature to increase blood pressure. This medication has been used off-label by some clinicians in the hypotensive HFrEF population to increase blood pressure and has been reported to have beneficial effects in improving GDMT utilization as well as increasing left ventricular ejection fraction (LVEF) in published case reports/case series. There does not exist any randomized prospective data on the use of midodrine in the hypotensive HFrEF population. The investigators' objective is to complete the first open-label, randomized control trial of midodrine in the hypotensive HFrEF population to demonstrate feasibility in performing a trial in this patient population and to show efficacy in increasing blood pressure without associated harm. The results of this trial will be used as the foundation and rationale for future studies assessing the impact of midodrine use on GDMT utilization as well as hard cardiovascular outcomes in the hypotensive HFrEF population, including hospitalizations for heart failure and mortality.

Ketones in Heart Failure With Reduced Ejection Fraction
The purpose of this study is to understand the effects of a ketone drink on exercise capacity and other cardiovascular parameters in patients with heart failure. In heart failure, patients are limited in their ability to do all the things they want to do, and exercise as much as they would like, due to becoming tired and short of breath early. There may be several reasons why these symptoms occur. This study is assessing whether the ketone drink can improve these symptoms. This drink has been given status by Food and Drug Administration as "generally regarded as safe". The use of DeltaG in this study is experimental. DeltaG has not been approved by the Food and Drug Administration (FDA) for the use being evaluated in this study.

STEPwise De-escalation and Optimizing Withdrawal of ARNI and SGLT2i in Normalized Heart Failure
This is a multicenter, randomized, open-label pilot study to evaluate whether stepwise withdrawal of two heart failure medications-angiotensin receptor-neprilysin inhibitor (ARNI) and sodium-glucose cotransporter-2 inhibitor (SGLT2i)-is safe in patients with Heart Failure with improved Ejection Fraction (HFimpEF) whose underlying structural cause (valvular heart disease or ischemic cardiomyopathy) has been completely corrected by surgery or intervention. Eighty adult patients (40 per arm) whose left ventricular ejection fraction (LVEF) has recovered to 50% or higher and whose NT-proBNP is ≤ 250 ng/L will be randomized 1:1 to either (1) stepwise withdrawal of ARNI followed by SGLT2i over one month under close echocardiographic monitoring, or (2) continuation of their current guideline-directed medical therapy. The primary outcome is the change in LVEF at 12 months, with non-inferiority of the withdrawal strategy declared if the LVEF decline is within 5 percentage points of the continuation arm. Secondary outcomes include cardiovascular death, heart failure hospitalization, NT-proBNP, quality of life (KCCQ-12), 6-minute walk distance, and adverse events. Results from this pilot will inform the design and sample size of a subsequent definitive non-inferiority trial and may provide initial evidence to guide deprescribing decisions in clinical practice.

Respiratory Sinus Arrhythmia (RSA) Pacing Post-CABG Surgery in Patients With HFrEF
The goal of this clinical trial is to test a new type of pacemaker in heart failure patients following a heart bypass operation. The new pacemaker restores respiratory sinus arrhythmia which is a natural pattern where the heart rate increases when the participants breathe in and slows down when participants breathe out. The main questions the trial aims to answer are: * Is the new type of pacemaker safe? * Does the new type of pacemaker improve how patients' hearts work (also known as cardiac output)? Participants will have a range of tests before their operation and during their recovery in hospital while participants have the new type of pacemaker in place, and will be monitored very closely. Participants will also receive a phone call 1 month after their surgery. Researchers will compare the new type of heart pacing against standard treatment to see if it is as safe, and if it is any better for patients.

Lumacaftor Yields Reversal of Impaired Cerebral Blood Flow in Heart Failure Patients
Cognitive impairment (CI) is highly prevalent in patients with heart failure with reduced ejection fraction (HFrEF), which has significant implications for disease management, quality of life and clinical outcomes. Currently, there are no specific treatments for CI aside from the current standard of care therapy for HF, making this a high unmet medical need. Impaired cerebral autoregulation is a proposed mechanistic factor that leads to cerebral hypoperfusion, ischemic damage and the development for CI. Preclinical data indicates that restoring CFTR-protein expression normalizes cerebral microvascular function and cerebral blood flow (CBF) in models of HF. The purpose of this study is to investigate whether CFTR-targeting therapy enhances cerebral perfusion and cognitive function in heart failure patients using the CFTR-corrector Lumacaftor.

Implementation and Interaction of Clinician And Patient-facing Tools Aiming to Intensify Neurohormonal Medicines for Heart Failure
An increasing number of guideline-directed medical therapies (GDMT) have been developed for patients with chronic heart failure with reduced ejection fraction (HFrEF). When used in combination at recommended doses, patients often experience significant improvements in cardiac function, quality of life, and survival.1,2 However, GDMT underuse occurs for the vast majority of patients with HFrEF. Two recent trials demonstrated improved GDMT prescribing during a clinic visit, each using automated delivery of a patient-centered decision support tool to promote a proactive and holistic approach to prescribing: EPIC-HF (NCT03334188) tested a brief video and checklist document sent to patients just prior to a clinic visit encouraging them to work with their clinicians to make at least 1 positive change to their GDMT; PROMPT-HF (NCT05433220) tested tailored electronic health record (EHR) alerts for GDMT intensification delivered to clinicians during clinic visits. The current I-I-CAPTAIN-HF study aims to broadly implement and test the EPIC-HF patient-facing and PROMPT-HF clinician-facing tools for HFrEF medication intensification at 5 health systems around the country through a pragmatic cluster-randomized implementation-effectiveness trial. This will occur through an initial phase of adaptation of the 2 tools at each health system. Once ready, the 2 tools will be tested using a 2x2 randomization at the clinician-level. In parallel, formal assessment of the implementation of EPIC-HF and PROMPT-HF will work to understand the most effective means of intervention design and delivery, as well as adaptations due to contextual factors to optimize use.
