The main purpose of this study is to observe outcomes of sodium-glucose co-transporter 2 inhibitors (SGLT2i) in heart failure (HF) patients with left ventricular assist devices (LVAD).
NCT03999138
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.
NCT06762964
The purpose of this research is to determine whether treatment with the study drug dapagliflozin for 3 months affects peripheral venous pressure at rest and during exercise in adults with failing Fontan circulation.
NCT03103932
This is a multi-centre, single blind, randomized study. Patients admitted to hospital with acute decompensated heart failure will be randomized to biomarker guided discharge algorithm vs usual care in a 2:1 ratio. NTproBNP and other biomarkers will be measured within 24 hours of admission. The NTproBNP results will be used to further stratify participants randomized to the biomarker guided group into lower and medium to higher risk pathways. Biomarkers will be repeated after 2-3 days and again prior to discharge. Specific care pathways will be followed for each of the lower risk and medium-higher risk groups. Biomarkers will be repeated 30 days post discharge. Participants will be followed with a phone call at 3 months and return for a follow up visit at 6 months post discharge for outcome evaluation.
NCT04347655
Background There are significant limitations in the current approaches to assessing 2 important areas of cardiovascular physiology - the systemic circulation and left ventricular (LV) performance. The investigators' have repurposed the concepts of "systemic vascular conductance" to assess systemic circulation, and the "head capacity principle" to assess LV performance. The investigators' now seek to test these concepts in human adults, with heart failure and without heart failure, using non-invasive methods. Hypothesis There will be a depressed head-capacity curve and reduced power among patients with heart failure which will indicate compromised left ventricular pump function. Methods The research study will involve a single outpatient visit per subject. The study will take place with the subject supine on a bed/table. The subjects will be instrumented with EKG electrodes and finger blood pressure cuffs. The continuous finger BP device performs a waveform analysis in real-time to determine the non-invasive stroke volume, cardiac output, and blood pressure. The patient will be supine for at least 5 minutes to collect baseline data before being handed a dynamometer device. The subject will then be asked to squeeze the dynamometer with maximum force for a minimum of 2 minutes while only engaging their forearm and remaining relaxed in the rest of their body. The subject will then release the dynamometer and remain supine, in recovery, for a minimum of 5 minutes. Following the handgrip test, the instrumentation will be removed and the patient's participation in the study will be complete. The study duration should be about 20 min.
NCT07558902
This is a single-center, prospective, single-arm clinical trial to evaluate the efficacy and safety of renal denervation (RDN) using a multi-channel radiofrequency ablation system in patients with symptomatic heart failure, including both heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF). The primary objective is to determine whether RDN can reduce serum N-terminal pro-brain natriuretic peptide (NT-proBNP) levels from baseline to 6 months post-procedure, and improve functional exercise capacity as measured by the six-minute walk test (6MWT). Approximately 20 eligible participants will undergo the RDN procedure while continuing their optimal guideline-directed medical therapy for heart failure. Assessments will be performed at baseline (pre-procedure), and at 30 days, 3 months, and 6 months post-procedure. Key evaluations include NT-proBNP measurement, echocardiography, 6MWT, New York Heart Association (NYHA) functional class assessment, and safety monitoring for adverse events. The study aims to provide preliminary clinical evidence on the effects of multi-channel RDN on cardiac biomarkers, functional status, and safety in heart failure patients, and to explore its potential as an adjunctive therapy for this population.
NCT07096726
The purpose of this study is to analyze the utility of a novel five-point ultrasound as a predictor of volume overload in diverse patients who are admitted with volume overload/congestive heart failure (CHF) exacerbation at Boston Medical Center (BMC), the largest safety-net hospital in New England. Current standard of care (SOC) involves the utilization of laboratory markers and physical exam, which is often inconsistent and equivocal. The investigators will assess will assess if ultrasound-assisted diuresis reduces recurrent episodes of volume overload/decompensated heart failure.
NCT07083011
The purpose of this study is to assess the performance of 68Ga- FAPI PET in heart failure with preserved ejection fraction (HFpEF)
NCT06307652
This is a Phase III, international, multi-centre, randomised, double-blind, parallel-group, double-dummy, active-controlled, event-driven study in patients with chronic HF and impaired kidney function who had a recent HF event. The aim is to evaluate the effect of balcinrenone/dapagliflozin vs dapagliflozin, given once daily on top of other classes of SoC, on CV death and HF events.
NCT07352891
DigiCare-HFrEF is an investigator-initiated, multicentre, randomised, open-label, endpoint-blinded, superiority trial designed to evaluate whether a structured digital remote-management platform can optimise guideline-directed medical therapy (GDMT) in patients with heart failure with reduced ejection fraction (HFrEF) after hospital discharge. Eligible adults (≥18 years) with a confirmed diagnosis of HFrEF within the past 3 months (left ventricular ejection fraction ≤40%) who are not optimally treated with GDMT-defined as at least two of the four foundational drug classes (ACEi/ARB or ARNi, β-blocker, MRA, SGLT2 inhibitor) either not initiated or prescribed at \<50% of the target dose-will be randomly assigned in a 1:1 ratio to digital remote management or usual care. In the intervention arm, patients will report symptoms and key physiologic measures (e.g., blood pressure, heart rate, and body weight) via the platform; an algorithm will perform risk stratification and generate GDMT optimisation suggestions and decongestion prompts, as well as a comprehensive management for core health metrics, which are reviewed and confirmed by clinicians before implementation. The primary endpoint is the change in GDMT score from baseline to 3 months (ΔGDMT).
NCT06280820
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.
NCT07400042
The purpose of the study is to determine if there is a reduction in the length of stay and rates of rehospitalization for patients diagnosed with congestive heart failure when physicians are provided daily measurements of peripheral venous pressure versus no daily measurements of peripheral venous pressure.
NCT07550790
The K-PROSE study is a randomized clinical investigation evaluating strategies to prevent contrast-induced acute kidney injury (CI-AKI) in patients hospitalized with acute heart failure and moderate renal dysfunction (eGFR 30-75 mL/min/1.73 m²). Patients requiring contrast-enhanced CT imaging are randomized to either standard intravenous saline hydration or a furosemide-based decongestion strategy. Renal function is assessed using serial measurements of creatinine and cystatin C, before and after contrast exposure. By comparing renal outcomes, congestion status, and safety profiles, this study aims to determine whether a decongestion-focused approach provides superior renal protection compared with conventional hydration in high-risk acute heart failure patients.
NCT07037459
This trial will examine if maridebart cafraglutide as an adjunct to standard of care will lead to a reduction in heart failure (HF) events such as HF hospitalizations and urgent HF visits, cardiovascular (CV) deaths and improvement in HF symptoms in participants with HF with preserved ejection fraction (HFpEF) and HF with mildly reduced ejection fraction (HFmrEF) who are obese. This is a phase 3, global, multicenter, 2-part trial with a double-blind period and an open-label extension (OLE). The trial is event-driven, and Part 1 will conclude when approximately 850 primary endpoint events have occurred.

NCT06158698
Two-parallel groups randomized, single-blinded, multi-center phase III controlled trial in patients with chronic inflammatory cardiomyopathy to assess the efficacy of colchicine and associated prospective registry to assess the prognostic value of positive genetic testing in this population.
NCT06148935
This is an observational study in which only data are collected from participants receiving their usual treatment. The study is done in people with chronic heart failure with reduced ejection fraction (HFrEF). HFrEF is a long-term condition in which the heart does not pump blood as well as it should. Blood and fluid may collect in the lungs, blood vessels, and tissues causing shortness of breath or tiredness. Over time, heart failure can lead to other serious medical conditions that may result in hospital stays and death. The study treatment vericiguat works by increasing the activity of an enzyme called soluble guanylate cyclase (sGC). sGC helps to regulate the heart and blood circulation. Vericiguat has already been studied in previous clinical studies and is available for doctors to prescribe to people with heart failure. This study will collect important data from real-world setting in Korea. The participants of this study are people with HFrEF who will receive vericiguat as prescribed by their doctors according to the approved product information The main purpose of this study is to learn more about how safe vericiguat is in the participants. To do this, researchers will collect data on all medical problems (also called adverse events) that the participants have during the study. Doctors keep track of all adverse events, even if they do not think they might be related to the study treatment. Further, researchers will collect data on how well vericiguat works and treatment patterns in the participants. For this, the following information will be collected: * occurrence of death due to heart and circulatory events * hospital stays due to heart conditions (failure) * dose levels of vericiguat and duration of treatment The data for this study will come from medical records and visits that take place in routine practice. Participants will be treated with vericiguat and observed up to 12 months or until death or they leave the study, whatever comes first.
NCT07188805
Researchers are looking for a better way to treat children who have heart failure with left ventricular systolic dysfunction (LVSD). Heart failure is a serious condition where the heart is unable to pump enough blood to meet the body's needs. This can lead to symptoms like shortness of breath, fatigue, and poor growth in children. The study treatment, finerenone (also called BAY94-8862), works by blocking a protein involved in inflammation, scarring, and thickening of the heart and blood vessels. This may help the heart to pump blood more effectively. This is the first study to explore its use specifically for children with heart failure and LVSD. The main purpose of this study is to learn if finerenone works to help the heart compared to placebo in children with heart failure and LVSD. For this, the researchers will collect and analyze data on the levels of a protein called NT-proBNP in the blood, which indicates heart stress, and monitor the safety of the treatment. The study will include children with heart failure and LVSD aged from 6 months to less than 18 years. The study participants will be randomly assigned to one of two treatment groups. Based on their group, they will receive either finerenone or a placebo for a duration of 3 months. A placebo looks like a treatment but does not have any medicine in it. Throughout the study, all participants will continue to receive their standard heart failure treatments. At the start of this study, the doctors will check each participant's medical history and current medications. If participants qualify for the treatment phase, they will undergo treatment for about 90 days. During this time, they will visit the study site at least 3 times. During these visits, the participants will: * have their blood pressure, heart rate, temperature, respiratory rate, height and weight measured * have their heart examined by electrocardiogram (ECG) and echocardiogram * have blood samples taken * have physical examinations * answer questions about their medication and whether they have any adverse events, or have their parents or guardians' answers An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments. After the initial three-month study, eligible participants will have the option to join a nine-month open-label extension study where all will receive finerenone. Participants who choose not to enroll in the extension will have a follow-up visit 30 days after their last treatment.
NCT07396792
It is a prospective, controlled, single-center, observational, non-randomized study. The study is planned to include at least 4000 patients 18 years old and older in the training sample and 1000 patients over 18 years old in the test sample (the total number of patients is at least 5000 people). Patients will be included in the study if they have undergone a full examination (laboratory, clinical and instrumental), allowing for the verification or exclusion of cardiac and cardiac-associated pathology in accordance with current recommendations. During the course of the study, the authors of the work do not interfere with the above-mentioned scope of the examination, which is carried out on patients in accordance with clinical guidelines. All patients included in the study will undergo ECG recording in standard lead I for 1 minute twice, followed by spectral analysis of the obtained data, which will be stored at the remote monitoring center of Sechenov University without being linked to the personal data of patients. A spectral analysis of the electrocardiogram will be performed using a continuous wavelet transform. The result of this study will be the identification of ECG parameters that will correlate with cardiac and cardiac-associated pathology
NCT06874556
The purpose of this research is to see if having community paramedic (CP) visit patients at home to manage their heart failure help them stay out of the hospital and improve their overall health compared to standard care. The investigators want to find out if their approach is better for patients in terms of their quality of life, hospital stays, emergency visits, and cost. The investigators are also looking to see how happy patients and doctors are with this method and if it's a practical and sustainable option for the future.
