Researchers are testing a more accurate way to measure how much fluid is in the lungs (also called pulmonary edema, or "increased lung water") in people with Heart Failure (HF) using MRI (Magnetic Resonance Imaging). There is little known about the exact level of lung water in patients with AHF or how these levels change from the time of hospital admission to discharge. The purpose of this research study is to measure the lung water in patients hospitalized for HF, to determine the change in lung water over the course of hospitalization and treatment, and to find out if lung water levels can predict if patients are higher or lower risk for returning to the hospital or dying from heart failure.

This study will evaluate the feasibility and safety of achieving therapeutic concentrations of beta-hydroxybutyrate using continuous infusion of D-beta-hydroxybutyrate monoester administered via a nasogastric tube in patients with acutely decompensated heart failure with reduced left ventricular ejection fraction.
NCT07530029
Acute heart failure (AHF) is the leading cause of hospitalization in people over 65, with the group with preserved ejection fraction (HFpEF) being the most closely related to aging. Among its comorbidities, sarcopenia stands out, and its assessment requires measurement of muscle mass. Muscle ultrasound is an accessible and economical alternative, although its prognostic value is still uncertain. The presence of common pathophysiological mechanisms between HF-PEF and sarcopenia leads to the study of biomarkers to improve their characterization. Multimodal characterization of sarcopenia, integrating muscle mass and strength with skeletal and cardiac muscle biomarkers, will improve prognostic stratification at discharge in elderly patients with HFpEF hospitalized for ACS. We seek to evaluate the prognostic value of muscle mass estimated by ultrasound, in combination with strength measurements and circulating biomarkers related to sarcopenia, as this could improve the prediction of clinical events after hospitalization for AHF in elderly patients with HFpEF. In addition, ultrasound estimation of muscle mass will be analyzed against BIA, the relationship between skeletal and cardiac muscle will be characterized, and the usefulness of the multimodal approach to sarcopenia will be evaluated. This study is observational, prospective, and single-center. It will include 110 patients hospitalized for AHF aged ≥80 years. Events will be monitored for 6 months after discharge. Variables include clinical data, ultrasound data (lung, VExUS, and muscle mass), congestion markers (BNP, CA125), biomarkers (GDF-15, sST2, BDNF, and myostatin/follistatin), bioimpedance, and dynamometry. Data will be analyzed using regression models and survival analysis to identify prognostic factors. This study has the potential to improve the clinical management of patients with acute heart failure by providing key information on its interaction with sarcopenia. The results could help identify more effective strategies to reduce rehospitalization and mortality in these patients, improving their prognosis and quality of life.
NCT07263035
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.
NCT07515508
The goal of this observational study is to learn whether information collected during routine hospital care, together with blood and urine samples, can help doctors better identify different types of cardiogenic shock and better predict outcomes in adults hospitalized with acute heart failure and cardiogenic shock. The main question is whether clinical findings, imaging results, and biomarkers, including sex-specific factors, are associated with the risk of death within 30 days. Participants will not receive an experimental treatment. Researchers will collect data from routine care, collect additional blood and urine samples for biobanking, and follow participants after hospital discharge
NCT07499661
This study focuses on two serious and common medical conditions: heart failure and pulmonary embolism (a blood clot in the lungs). Heart failure happens when the heart cannot pump blood effectively, and it is one of the main reasons older adults are admitted to the hospital. Pulmonary embolism can be life-threatening and may worsen heart failure or even trigger it. Doctors believe that pulmonary embolism may often go undetected in patients who come to the hospital with symptoms of acute heart failure, such as sudden shortness of breath. This is because both conditions can cause similar symptoms, making it difficult to tell them apart. As a result, doctors may sometimes assume the symptoms are only due to heart failure and not investigate further for a possible blood clot. However, missing a pulmonary embolism can have serious consequences. Studies suggest that some patients with heart failure who die may actually have had an undiagnosed pulmonary embolism. Current medical guidelines recommend checking for pulmonary embolism when the cause of breathing problems is unclear, but in real-life practice, this is not always done. The goal of this study is to find out whether pulmonary embolism is underdiagnosed in patients with suspected acute heart failure and whether systematically testing for it could improve patient outcomes. To do this, the study will compare two approaches in several hospitals. In half of the hospitals, doctors will follow their usual practice and decide case by case whether to test for pulmonary embolism. In the other half, doctors will systematically test all eligible patients for pulmonary embolism using recommended diagnostic methods. Adult patients admitted with recent or worsening breathing difficulties and signs of acute heart failure may be included in the study, provided they give their consent. Researchers will collect information about their symptoms, tests, diagnosis, and treatments. Patients will be monitored during their hospital stay and for three months afterward. The study will track important outcomes such as survival, new blood clots, bleeding events, repeated hospital visits for breathing problems, and overall time spent in the hospital. The researchers expect to include about 740 patients in total. They estimate that pulmonary embolism may be found in about 1% of patients with usual care, but up to 5% when doctors systematically look for it. This study aims to better understand how often pulmonary embolism occurs in patients with acute heart failure and whether more systematic testing could lead to earlier diagnosis and better care. The results could help improve medical practice and reduce complications or deaths related to missed diagnoses.
NCT07484009
This clinical trial aims to determine whether a ReDS-guided treatment strategy is superior to the current standard of care for adults hospitalized with heart failure. Additionally, the study will evaluate the safety and cost-effectiveness of this approach. The study seeks to answer the following key questions: 1. Does the ReDS-guided strategy reduce the risk of cardiovascular events during the first month following hospital discharge? 2. What is the safety profile of this treatment strategy? Researchers will compare the ReDS-based strategy against the current standard of care. All participants will: * Undergo daily assessments using the ReDS device throughout their hospitalization. * Attend two follow-up visits post-discharge, scheduled at 2 weeks and 30 days.
NCT07469722
Acute decompensated heart failure (ADHF) is a frequent cause of hospitalization and is associated with high morbidity and mortality. Congestion is the primary pathophysiological mechanism leading to clinical deterioration and hospitalization in ADHF. Diuretics remain the cornerstone of treatment for most ADHF phenotypes; however, evidence regarding optimal strategies to guide diuretic therapy during the decongestion process is limited. Recently, point-of-care ultrasound (POCUS) has emerged as a promising tool to support clinical assessment in ADHF, improving diagnostic accuracy, prognostication, and pre-discharge evaluation. Nevertheless, the role of POCUS in guiding therapeutic management in ADHF remains uncertain. To specifically assess congestion in patients with ADHF, a pragmatic POCUS-based score, the Dynamic Ultrasound Congestion Score (DUCS), was developed. DUCS integrates lung ultrasound and Venous Excess Ultrasound (VExUS) to dynamically evaluate congestion severity, treatment response, and therapeutic goals during ADHF management. Observational data suggest that DUCS is associated with in-hospital outcomes and short-term prognosis, and correlates with markers of decongestion such as urinary output and weight loss. This study is a randomized, single-center, single-blind clinical trial designed to evaluate whether a DUCS-guided POCUS strategy improves clinical and decongestion outcomes compared with standard of care. Eligible patients hospitalized due to ADHF will be randomized within 48 hours of admission to one of two groups: (1) diuretic treatment guided by institutional standard-of-care combined with information from the EVEREST congestion score assessment and guideline-based treatment recommendations; or (2) diuretic treatment guided by serial DUCS-based POCUS assessments used to inform diuretic adjustment recommendations. Participants in both groups will undergo evaluations at baseline (day 1), day 2, day 3 and day 5, including clinical data collection, physical examination using the EVEREST congestion score, and standardized DUCS-based POCUS assessments. Outcomes to be assessed include in-hospital mortality, length of hospital stay, decongestion parameters, and changes in biomarkers.
NCT06682260
This study aims to understand how nitroglycerin affects patients with acute heart failure, a condition where the heart struggles to pump blood effectively, leading to fluid buildup and breathing difficulties. Nitroglycerin relaxes blood vessels to ease the heart's workload and may help reduce fluid buildup. The investigators hypothesize that nitroglycerin can increase blood flow from the heart and promote urine production, which may reduce congestion in AHF patients. By studying heart function, blood volume, and fluid levels during treatment, the goal is to identify which patients may benefit most from nitroglycerin therapy.
NCT06967441
Patients admitted to the cardiology department with acute heart failure who have a nasopharyngeal respiratory virus PCR test performed within 72 hours of admission will be enrolled in the study cohort. The detection rate of respiratory viruses including influenza virus, RSV, and coronavirus will be analysed. The investigators will also look for seasonal changes in the frequency of respiratory viruses and differences in the clinical presentation of heart failure based on respiratory virus infection.
NCT07439081
Heart failure is a leading cause of hospitalization and readmission, particularly among older adults with multiple comorbidities. Traditional outpatient follow-up may be insufficient to detect early clinical deterioration in this vulnerable population. Remote patient monitoring (RPM) using non-invasive symptom and weight tracking has been proposed to enhance ambulatory care, but its effectiveness appears to depend on integration within structured care pathways. The OPTIMUM study evaluated the real-world implementation of an integrated ambulatory heart failure care pathway combining non-invasive RPM with multidisciplinary follow-up in routine clinical practice. Patients enrolled after a recent heart failure hospitalization were managed using the Satelia® Cardio monitoring system, nurse-led therapeutic education, and a planned cardio-geriatric day-hospital reassessment. The study aimed to describe pathway implementation and assess associations with rehospitalizations, mortality, alert activity, and patient and healthcare professional satisfaction in an older, frail population.

Ketones have been suggested to have significant physiological effects in patients with heart failure. Potential mechanisms for these effects include energy provision for the failing heart and direct protective effects on other organs. Despite the strong physiological rationale, the acute effects of ketone therapy in patients with acute heart failure (AHF) is unclear. AHF is a major healthcare issue, with in-hospital mortality exceeding 10%. Therefore, we propose a vanguard randomized controlled trial to assess the effects of ketone esters in patients with AHF. Sixty patients hospitalized with AHF will be randomized to receive either 25 grams of ketone esters three times per day or a matching placebo for five days, or until death or hospital discharge. We hypothesize that ketone therapy will improve markers of systemic congestion and heart failure symptoms. Primary endpoint will be changes in NT-proBNP levels during therapy. Secondary endpoints will be KCCQ scores, and hemodynamic profile as assessed by echocardiogram. Exploratory endpoints will clinical outcomes including mortality, need for intensive care unit admission, among others.

The EMPA-AHF trial is a multicentre, randomized, double-blind, placebo-controlled trial designed to evaluate the efficacy and safety of early initiation of once-daily oral empagliflozin 10 mg in patients hospitalized for patients with acute heart failure (AHF) who are at a high risk of adverse events.
NCT05518396
Acute heart failure is a life-threatening condition where the heart is suddenly unable to pump blood around the body. It can be challenging to diagnose because the symptoms often mimic other conditions. Previous studies have showed that delays in making the correct diagnosis result in worse outcomes. We therefore developed a decision-support tool called CoDE-HF that uses a computer algorithm to combine levels of a blood test called NT-proBNP with patient factors to calculate the probability of acute heart failure for an individual. In this project, we wish to evaluate the performance of CoDE-HF in approximately 2,000 patients attending the Emergency Department with suspected acute heart failure. We will store surplus material from their blood tests to measure NT-proBNP and link information from their electronic health records with other routinely collected medical information in regional and national databases in order to evaluate this algorithm.
NCT07321509
The DIG-DICA trial is a randomized, controlled, open-label, single-center study designed to evaluate whether adding low-dose digoxin to optimal medical therapy after an episode of acute decompensated heart failure improves patients' clinical status and quality of life. The study enrolls adults with heart failure with reduced ejection fraction (HFrEF) who have recently stabilized after hospitalization or urgent care for decompensation. The primary aim is to determine whether digoxin increases the proportion of patients who are "Alive and Well" at 180 days-defined by achieving a Kansas City Cardiomyopathy Questionnaire (KCCQ-12) score ≥75. The trial also explores effects on symptoms, functional capacity, biomarkers, renal function, and major cardiovascular events. The goal is to clarify whether modern low-dose digoxin provides meaningful clinical benefit in contemporary heart failure management.

Renal Compromise after treatment of decompensated heart failure with diuretics is not uncommon. The purpose of our study is to investigate the relationship between cystatin C and worsening renal function in this setting. Cystatin C is a biomarker produced at a constant rate by all cells that is a sensitive biomarker of renal function.Cystatin C and Plasma amino terminal proB-type natriuretic peptide (NT-proBNP) levels will be obtained at baseline and daily. Our goal is to enroll 100 subjects with an estimated 5 samples per each subject. The time course of changes in cystatin C in relation to serum creatinine levels over time will be plotted. Our hypothesis is that sequential changes in cystatin C levels following initial treatment with diuretic therapy in the setting of acute decompensated heart failure may provide early insight into cardio-renal compromise. Understanding the natural history and time course of the changes in sequential cystatin C levels may facilitate further studies to guide the judicious use of diuretic therapy in acute decompensated heart failure, and to predict the risk of subsequent development of worsening renal function. If serial testing of cystatin C can provide accurate assessment and prediction of worsening renal function, clinical applications of these observations can be evaluated in future prospective studies.

NCT06595290
VN-RAPID is an open-label, multicenter, randomized controlled trial evaluating the safety and efficacy of in-hospital initiation and rapid up-titration of four-pillar therapy for hospitalized Asian patients with acute heart failure (AHF) and reduced ejection fraction (HFrEF). The study compares a standardized protocol of intensified treatment (high-intensity care arm) with usual care in patients with elevated NT-proBNP levels who are not on optimal HFrEF medications. The high-intensity care arm involves initiation of all four pillars of HFrEF therapy (RAS inhibitor, beta-blocker, MRA, and SGLT2i) before discharge, followed by a structured 6-week outpatient up-titration process with frequent follow-ups. The study aims for 75% of target doses for RAS inhibitors and beta-blockers, considering the lower blood pressure tendency in Asian populations. Participants will be followed for 180 days to assess clinical outcomes.
NCT03806972
Heart failure (HF) is the leading cause of hospitalization ,rehospitalization and mortality for adults over 65 years of age. This study aimed to assess mortality, and hospitalization rates at 30 days and one year after dicharge of patients with heart failure (HF) with reduced ejection fraction (HFrEF) compared to HF with preserved ejection fraction (HFpEF).
NCT05461547
Acute heart failure (AHF) is a major reason patients seek emergency care and is a significant public health burden. The ability to differentiate AHF from other etiologies of dyspnea remains a challenge as symptoms and physical exam findings overlap, especially in the pre-hospital setting where diagnostic tools are not readily available. The inability to differentiate AHF from other causes of dyspnea leads to misdiagnosis, delays in diagnosis, and ultimately delays in appropriate treatment. Delays in initiating HF therapies is associated with poor outcomes including higher rates of in-hospital mortality and longer hospital length of stay. Optimizing treatment for AHF in the pre-hospital setting is associated with increased survival and lower rates of hospital re-admission. Thus, accurate diagnosis and early treatment for AHF in the pre-hospital setting remains a critical unmet need. Lung ultrasound (LUS), through assessment of B-lines, allows for an easy and accurate method for detection of pulmonary congestion seen in AHF patients. Although multiple studies have shown LUS is easy to learn, there is a paucity of data assessing clinical impact of LUS in the pre-hospital setting. The investigators hypothesize that the use of LUS by pre-hospital personnel will improve accuracy for detecting AHF in the pre-hospital setting when compared to usual care (no LUS). Specific Aims: To determine if the use of pre-hospital LUS improves diagnostic accuracy for detecting AHF in patients transported by emergency medical services (EMS) for acute dyspnea when compared to usual care (no LUS).
