Multi-Scale Analysis of Phenotypes in Heart Failure (MAP-HEART)
Background: More than 6.5 million people in the United States live with heart failure (HF), and more than a million new cases are diagnosed each year. Treatments have improved in recent years, but researchers want to understand more about how HF develops. To do this, they need to compare blood and other samples from many people with HF. Objective: To collect blood and other samples from people with HF. These samples will be used to identify and study proteins and other factors that may lead to decreased heart function over time. Eligibility: People aged 18 years and older with heart failure. Design: Participants will be asked to join the study based on a review of their medical records. They will have 1 study visit. They will provide a blood sample: About 3 tablespoons will be collected from a needle inserted into a vein. Other tests are optional: Participants may provide urine and stool samples. They may have a cotton swab rubbed on the inside of the mouth to collect DNA. Participants may also take 3 questionnaires. They will answer questions about dietary, social, and other factors that affect their health. Participants will receive compensation. Researchers will follow the participants health by monitoring their medical records for up to 5 years.

Smartphone Twelve-Lead ECG Utility In ST-Elevation Myocardial Infarction II
AliveCor (www.alivecor.com) has developed several electrocardiogram (ECG) devices that interface with iOS and Android smartphones and tablets via various Kardia apps. The current Kardia family of devices can measure single lead and six limb-lead ECGs, depending on the device. KardiaMobile, KardiaMobile 6L, and KardiaMobile Card have FDA clearance for ECG rhythm recording. A modified single-lead Kardia smartphone 12-lead ECG was previously validated in the multicenter ST LEUIS study for the diagnosis of ST-Segment Elevation Myocardial Infarction (STEMI) and Non-ST-Elevation Myocardial Infarction (NSTEMI). Recently, AliveCor developed a new device: AliveCor (AC) 12-lead (12L) ECG System to record simultaneously 4 leads of ECG and then generate complete 12-lead ECGs. A previous protocol at the University of Oklahoma involved 200 subjects with early prototypes of the AC 12L device with the specific aim to validate that it accurately generated 12-lead ECGs as compared to simultaneously acquired FDA-cleared 12-lead ECGs. The prototype version of the AliveCor 12L ECG System simultaneously measured four channels of ECG (leads I, II, V2, V4), calculated the remaining limb leads as is standard for 12-lead ECGs (Leads III, aVR, aVL, aVF) and synthesized the remaining 4 precordial ECG leads (V1, V3, V5, V6). This protocol will serve to validate the production version of the system against standard 12-Lead ECGs for the diagnosis of STEMI and NSTEMI in patients admitted to the Emergency Department or directly to the Cardiac Cath Lab for the evaluation of chest pain. It is anticipated that the waveforms for each of the 12 leads from the AC 12L ECG System will be highly correlated with the corresponding leads from the comparator commercially available 12-lead ECG devices used at participating sites. The purpose of this study is to clinically validate that the four-channel AC 12L ECG device can enable the diagnosis of STEMI and NSTEMI in a non-inferior manner to existing 12-lead ECG devices.

Urine Sodium-Driven Diuretic Adjustment Strategy in Acute Decompensated Heart Failure
The goal of this clinical trial is to learn if increasing the dose of diuretics to achieve a higher urine sodium target produces better clinical results when treating patients hospitalized with acute heart failure when compared to lower urine sodium target and standard of care. The main questions it aims to answer are: 1. Does targeting a higher urine sodium goal achieve greater natriuresis and diuresis? 2. Does targeting a higher urine sodium goal reduce frequency of hospital readmissions? 3. Does targeting a higher urine sodium goal reduce hospital length of stay? Researchers will compare natriuresis-guided arms with standard of care to see if targeting higher natriuresis goals improves significantly over current practice. Participants will submit urine samples at routine intervals after being given diuretics to evaluate urine sodium concentration. If urine sodium is low then diuretic dose will be increased.

Pulmonary Artery Sensor System Pressure Monitoring to Improve Heart Failure (HF) Outcomes
Randomized, parallel group controlled study examines the effect of supporting the Heart failure supply through pulmonary arterial (PA) pressure measurement with the CardioMEMS™ HF system to hard endpoints, safety and quality of life. The target population consists of heart failure (HF) patients who have been predominantly in New York Heart Association (NYHA) Stage III for the past 30 days and at least once in the past 12 months for HF were admitted to hospital. All patients receive basic care, which is based on structured telephone contact (between the care center, patient and family doctor) to optimize guideline compliant therapy. In the intervention group a PA pressure sensor is (CardioMEMS™-HF Sensor) implanted. These patients are structured by specially trained non-medical personnel aftercare with additional inclusion of the PA pressure values: adjusted to the basis of the information collected in PA monitoring the therapy is optimized. The follow-up period until the primary endpoint is 12 months. In addition, data on longtime-mortality is being collected towards the end of the study for all study participants.

The Assessment of Partial Guideline-Directed Medical Therapy Down Titration in Heart Failure in Remission.
Heart failure (HF) is a chronic condition that is characterized by a weakened and enlarged heart. It typically causes symptoms such as breathlessness and swelling of the legs, and it is a serious illness that shortens life expectancy. In recent years, new medicines have been developed that can improve heart function and help patients with HF live longer. HF patients with reduced heart function typically are recommended to take four different medicines for the rest of their lives. Some patients respond so well to treatment that their heart function and symptoms appear to recover; this is called HF in remission. While the four standard medicines have proven to increase lifespan in patients with heart failure with reduced heart function, it is not known whether they all need to be continued lifelong after recovery of the heart. Current guidelines recommend treating patients lifelong, yet this is based on limited scientific evidence. Lifelong therapy comes with disadvantages: it carries considerable costs for patients and health care systems, causes potential side effects, and makes it harder for patients to keep up with all their other medications. This study will test whether carefully reducing certain HF medicines is safe compared to continuing them. Patients with heart failure in remission will be randomly assigned to either: (1) continue all standard therapies, or (2) gradually reduce medicines to just two per day under close medical supervision. Patients will followed for two years to see whether their heart function remains stable. This will be measured by looking at echograms of the heart (echocardiograms), blood tests, and whether patients experience serious events such as hospitalizations or death. This study will investigate whether partial therapy discontinuation is safe and feasible.

AMEND-CRT: Mechanical Dyssynchrony as Selection Criterion for CRT
Previous experience with cardiac resynchronization therapy (CRT) candidates suggests that selection of these patients can be improved. Current clinical guideline approaches are mainly too unspecific and lead to a high non-responder rate of 30-40%, which causes a burden on health care systems and puts patients at risk of an unnecessary treatment who might benefit more from a conservative approach. Previous work indicated that using the assessment of mechanical dyssynchrony on echocardiography can lower the non-responder rate at least by 50% without compromising sensitivity for detecting amendable patients. The current prospective, randomized, multi-center trial was therefore designed to prove that the characterization of the mechanical properties of the left ventricle can improve patient selection for CRT. Patients will be randomized into one of two study arms: a control study arm with treatment recommendation based on clinical guidelines criteria, or an experimental study arm with treatment recommendation based on the presence of mechanical dyssynchrony. All patients will receive a CRT implantation. In the control study arm, bi-ventricular pacing will be turned on. In the experimental study arm, bi-ventricular pacing will be turned on or off, depending on the presence or absence of mechanical dyssynchrony, respectively. The primary endpoint will be non-inferiority in outcome of a treatment recommendation based on mechanical dyssynchrony, achieved with a lower number of CRT devices implanted, effectively leading to a lower number needed to treat. Outcome measures are the average relative change in continuously measured LVESV per arm and the percentage 'worsened' according to the Packer Clinical Composite Score per arm after 1 year follow-up.

Effect and Cost Effectiveness of a Dyadic Empowerment-based Heart Failure Management Program for Self-care
Global population aging has drastically increased healthcare spending worldwide, with the greatest portion going to hospital and community health services. Heart failure (HF), as the final form of many cardiovascular diseases resulting from insufficient myocardial pumping. Ineffective self-care is consistently identified as the major modifiable risk factor for HF decompensation requiring hospitalization. It refers to an active cognitive process that influence patients' engagement in self-care maintenance, symptom perception and self-care management. However, current studies pay much focus on interventions such as motivational interviewing and behavioural activation to enhance the HF-related self-care and health outcomes which only produces short-term benefits. In fact, the lack of a sustainable effect from the self-care supportive interventions might be related the use of patient-centric design in these studies, which totally ignores the fact that HF management takes place in a dyadic context. To advance, active strategies were adopted to mobilize collaborative effort of the dyad in actual disease management. This study aims to evaluate the effects and cost-effectiveness of a Dyadic empowerment-based Heart Failure Management Program (De-HF) for self-care, health outcomes, and health service utilization among HF patients who require family support after hospital discharge. The De-HF program is based on the Theory of Dyadic Illness Management to enhance the congruence in illness perception and active dyadic collaboration in managing HF via both face-to-face and online platforms.

Sotagliflozin in Patients With Heart Failure Symptoms and Type 1 Diabetes
People with type 1 diabetes sometimes develop heart failure which can cause symptoms like breathlessness, tiredness or ankle swelling, reduced quality of life and lead to being admitted to hospital or suffering potential fatal consequences. This trial is investigating if a tablet called sotagliflozin, can improve quality of life in people with type 1 diabetes and heart failure. In addition, this trial will also assess the safety and tolerability of sotagliflozin in this population. In previous trials that included people with type 2 diabetes and heart failure sotagliflozin was shown to improve patients' symptoms of heart failure, quality of life and reduce the chance of people with heart failure being admitted to hospital or dying. However, people with type 1 diabetes and heart failure were not included in these trials meaning that it is not known if these benefits also apply to this population. This trial aims to recruit 320 people with type 1 diabetes and heart failure symptoms in multiple sites in the United Kingdom (UK). This trial will compare the health and quality of life of participants who take sotagliflozin tablets with participants who take placebo tablets, which is a dummy tablet that looks the same as sotagliflozin. Participants will be randomly allocated to one of two groups (i.e. one taking sotagliflozin and the other the placebo) and both the medical team and participants will not know in which group each participant is until the end of the study. Participants will be in the trial for approximately 6 months and will be given sotagliflozin or placebo tablets to take 1 per day for 4 months. The trial is expected to run for a total of 26 months.
