2,316 Clinical Trials for Various Conditions
The goal of this study is to use the HepQuant dual cholate clearance assay, which has been shown to measure liver function in people with known chronic liver conditions, to assess severity of Fontan-associated liver disease (FALD). This study aims to understand the role impaired blood flow to the liver plays in liver function in Fontan patients compared to patients with right heart failure and healthy controls. The study will also determine whether cholate clearance is a good measure to use in this population, and whether it will be able to predict clinical outcomes. Participants will undergo a HepQuant dual cholate clearance assay and a cardiac magnetic resonance imaging (MRI) at the beginning of the study, and then data on health status will be collected for 5 years.
Measuring the impact of a guideline-based nutrition digital tool in heart failure patients
The primary objective of this study is to learn whether a morning dose of extended-release torsemide enhances renal sodium excretion after lunch (4-8 hours after dosing) compared to immediate-release torsemide. This is a randomized, double-blind, crossover study in patients with heart failure who are on a stable dose of a loop diuretic. During the study period, participants' current loop diuretics will be replaced with an equivalent dose of either immediate-release or extended-release torsemide. Following a one-week stabilization period on the assigned torsemide formulation, patients will report to the clinical site for an assessment visit. On the study day, patients will take a single dose of the same torsemide formulation they have been on for the past week, administered after breakfast. Urine samples be collected are: * 0-4 hours post-dosing (pre-lunch period) * 4-8 hours post-dosing (post-lunch period) * 8-24 hours post-dosing (24 hours period) The primary endpoint will be urinary sodium excretion (4-8 hours after dosing). This will be compared between the extended-release arm and the immediate-release arm to assess the efficacy of prolonged diuretic action. In addition, urinary potassium and creatinine excretion and creatinine clearance will be measured in all urine samples as the safety endpoints.
The researchers are studying whether an intervention that involves video-based educational content and a health coach is acceptable, feasible, and effective for people with Heart Failure with Preserved Ejection Fraction (HFpEF).
This cohort study aims to assess the comparative effectiveness of tirzepatide versus semaglutide with respect to cardiovascular events in patients with type 2 diabetes and heart failure with preserved ejection fraction.
This study will look into how CDR132L (a potential new medicine) works on the structure and function of the heart in people living with heart failure. Participants will either get CDR132L or placebo (a medicine which has no effect on the body), which treatment the participants get is decided by chance. The study will last for about 60 weeks.
Cardiac resynchronization therapy with a defibrillator (CRT-D) in heart failure (HF) patients without left bundle branch block (non-LBBB) has been less beneficial to improve outcomes despite being a guideline indicated therapy, posing a significant treatment challenge. However, non-LBBB patients with echocardiography response to CRT-D have better outcomes, and pre-implant variables could predict response, identifying patients who benefit the most. In this study, we plan to enroll 270 HF patients with non-LBBB and guideline-indicated CRT-D implantation to validate our prior echocardiography predictor score, and to identify novel ECG and echocardiography predictors using conventional statistics and machine learning analysis. We will also assess the applicability of such a score for clinical outcomes of HF, ventricular arrhythmias, or death.
This study will evaluate whether using bedside ultrasound (also called Point-of-Care Ultrasound or POCUS) can help improve the care of hospitalized patients with decompensated heart failure. Patients will be randomly assigned to two groups: one group will receive ultrasound-guided assessments, and the other group will receive standard clinical evaluations. Researchers will compare the hospital length of stay between the two groups. Ultrasound is a non-invasive, safe, and painless imaging tool. The goal of the study is to find out if ultrasound guidance can lead to shorter hospitalizations and better care for patients with heart failure.
The study will evaluate if Impella 5.5® support in heart failure reduced ejection fraction (HFrEF) patients presenting with decompensated heart failure (HF) and cardiogenic shock will facilitate the initiation and optimization of guideline directed medical therapy (GDMT) during the hospital stay and post-discharge.
This study is open to adults with chronic heart failure (HF) who have a reduced left ventricular ejection fraction (LVEF) of less than 40%. People can join the study if they have been diagnosed with chronic HF at least 3 months before the study. The purpose of this study is to find out whether a medicine called vicadrostat, in combination with another medicine called empagliflozin, helps people with chronic heart failure. In this study, participants are put into 2 groups randomly. Participants have an equal chance of being in either group. One group takes vicadrostat and empagliflozin tablets, and the other group takes placebo and empagliflozin tablets. Placebo tablets look like vicadrostat tablets but do not contain any medicine. Participants take the study medicines as tablets once a day for between 1 and about 3.5 years. During this time, they can continue their regular treatment for heart failure. Participants can stay in the study as long as they benefit from treatment and can tolerate it, for a maximum of about 3.5 years. During this time, they visit the study site regularly. The exact number of visits is different for each participant, depending on how long they stay in the study. The study staff may also contact the participants by phone. Participants also regularly answer questions about their well-being. The doctors document when participants experience worsening of their heart failure symptoms, must go to hospital due to heart failure, or die during the study. The time until these events are observed is compared between the treatment groups to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.
This project will develop and test a novel clinical decision support tool (CDS) that encourages timely referral to palliative care for people hospitalized with heart failure. This intervention will incorporate an existing, validated 1-year mortality risk model into a CDS to deliver prognostic information and evidence-based decision support at the point of care. Thus, this research may lead to improved care-concordant and goal-directed care for people with heart failure.
The purpose of this study is to find out if additional images taken during a stress echocardiogram study and risk score calculation will help the doctor determine if shortness of breath or chest pain are caused by stiff heart (heart failure with preserved ejection fraction or HFpEF).
Heart failure occurs when the heart cannot pump blood effectively, leading to fluid buildup in the body. This can cause problems such as difficulty breathing, swelling, and extreme tiredness. In severe cases, these symptoms worsen to the point where hospitalization is required. Unfortunately, many patients with severe heart failure are readmitted to the hospital within 30 days after discharge, which is both physically and emotionally challenging for patients and places a significant financial burden on individuals and the healthcare system. Although symptoms such as difficulty breathing and swelling may improve during the hospital stay, some patients are discharged with excess fluid remaining in their bodies. This retained fluid often causes symptoms to worsen, leading to subsequent hospital readmissions. Inadequate management of fluid levels can also harm the kidneys, further complicating the patient's condition. This study aims to improve care for heart failure patients by utilizing a simple, non-invasive tool to assess fluid levels more accurately at the bedside. The tool measures the size of a large blood vessel in the neck, providing key information about the pressure inside the heart. This information enables clinicians to determine the appropriate amount of medication needed to remove just the right amount of fluid. Properly managing fluid levels can help prevent kidney damage and improve overall patient outcomes. The primary goal of this study is to evaluate whether this tool can reduce the number of patients readmitted to the hospital within 30 days of discharge. A secondary goal is to determine whether the tool can help protect kidney function by allowing for better fluid management. If successful, this approach has the potential to help heart failure patients stay healthier, reduce hospital visits, and lower healthcare costs.

The objective of this study is to prospectively compare decongestive therapy administered by the Reprieve System to Optimal Diuretic Therapy (ODT) in the treatment of patients diagnosed with acute decompensated heart failure (ADHF). The main objective is to determine if the Reprieve System can more efficiently decongest ADHF patients in comparison to Control Therapy.
The purpose of this early feasibility study is to evaluate the safety and feasibility of the device for percutaneous shunting of the interatrial septum and improvement of heart failure related symptoms. The primary goal is to determine if the device is safe to use. The findings from this study may be used to refine the intended patient population, the design of the device, or develop a subsequent randomized study.
To work best, clinical decision support tools (CDS) must be timed to provide support when healthcare decisions are made, which includes virtual visits (phone or video). Unfortunately, most CDS tools are either missing from virtual visits or not designed for the unique context of virtual visits (e.g., availability of physical assessments and labs, different workflows), which could generate new inequities for patients more likely to use virtual visits. The objective of this study is to test the reach, feasibility and acceptability of a new CDS tool for heart failure with reduced ejection fraction (HFrEF) during virtual visits. This new CDS tool was developed through an iterative design process, and will be compared to an existing HFrEF CDS tool in a randomized pilot study at outpatient cardiology clinics throughout the UCHealth system.
Recent medical guidelines for the management of heart failure (HF) have established a combination of specific classes of medications as the best treatment for patients with heart failure with reduced ejection fraction (HFrEF). However, studies have shown that these medications, known together as guideline-directed medical therapy (GDMT), are not being used in clinical practice less often than they could be. Several tools to promote broader use of these treatments (including patient checklists) have shown promise for increasing use of GDMT. However, these tools have not been broadly implemented within large health systems. The goal of this study is to see if using these tools broadly within cardiology clinics will increase the use of GDMT. This study is important because it could help improve the use of GDMT, which may lead to improved patient care and outcomes.
This clinical trial investigates the safety and preliminary effectiveness of YAP101, a gene therapy designed to improve heart function in adults with ischemic heart failure and reduced ejection fraction (HFrEF). Ischemic heart failure, often resulting from a prior heart attack, leads to poor heart function and quality of life. Current treatments are limited, and there is an urgent need for new therapies. YAP101 works by delivering a gene therapy using a specialized vector to heart cells, targeting a pathway involved in heart repair. By temporarily activating heart muscle regeneration, YAP101 aims to restore damaged tissue, reduce scarring, and improve the heart's pumping ability. The study will enroll participants who will receive a one-time dose of YAP101 via a minimally invasive cardiac injection. Researchers will monitor participants over 12 months to assess safety and changes in heart function, exercise tolerance, and quality of life.
The goal of this clinical trial is to explore the impact that an at-home cardio-oncology rehabilitation (CORE) may have on short-term cardiovascular fitness and psychosocial wellness in pediatric cancer survivors. The main question it aims to answer are * To evaluate the efficacy of an at-home CORE model on short-term cardiovascular fitness and psychosocial wellbeing in adolescent cancer survivors. * To evaluate the exercise adherence rate among adolescents at risk for heart failure and assess barriers to compliance. * To explore which specific CORE resources are of most value to patients in creating sustainable healthy lifestyle modifications. * Hypothesis: Pediatric cancer survivors who implement exercise and dietary recommendations will demonstrate improvement in cardiovascular fitness and general wellness. A multidisciplinary team approach can facilitate adherence to a moderately rigorous exercise prescription, and thus enhance the health benefits of a CORE program at CHLA. Participants will undergo cardiovascular studies and a quality-of-life survey prior to exercise intervention, and at the end of the 6-month study period.
This observational study is being done to learn more about heart attack recovery in patients supported with the Impella 5.5 left ventricular assist device (LVAD) as part of their standard of care. There are three stages in this study: screening, treatment and post treatment. There will be two phases of enrollment: First phase will enroll 10 patients; second phase will enroll an additional 40 patients. Approximately 50 participants will take part in the study at Columbia University Irving Medical Center. Participation in this research is expected to last approximately 14 months. This time estimate includes a screening period for about 1- 3 days, treatment period of 40 days and post treatment follow-up period for 1 year. Data will be collected through 1- year after heart transplant. Clinical data (medical history, vital signs, laboratory assessments) from medical records, to perform functional and neurocognitive testing, and to obtain blood and discarded heart tissue from for the purpose of this research study. Participants will be asked to share their records for echocardiography, right heart catheterization, laboratory data and clinical information. Participants are required to complete an assessment a 6-minute walk, hand grip strength test and questionnaire to evaluate neurocognitive status.
The aim of this mixed methods randomized controlled trial is to test the integrated nurse-led intervention bundle for family home care management of end-stage heart failure and palliative care in rural Appalachia. This intervention bundle is designed to address rural disparities in access to health care, with the help of the faith-based nurses and local volunteer visiting neighbors.
This retrospective, non-randomized cohort study will evaluate how well the Cordella PA Sensor System works compared to standard medication treatment in people with chronic heart failure. The study will track patients for two years to see if those using the Cordella system have fewer deaths and hospitalizations related to heart failure.
The purpose of this study is to determine if transseptal extra-corporeal membrane oxygenation (ECMO) can bridge pulmonary hypertension- right heart failure (PH-RVF) patients to lung transplant safely.
The goal of this clinical trial is to learn if using point-of-care ultrasound (POCUS) can increase participant engagement and changes in behavior among adults with risk factors for pre-symptomatic heart failure presenting to the emergency department. The main questions it aims to answer are: 1. Does POCUS increase understanding of heart failure and the likelihood to improve diet, exercise, and follow up? 2. Does POCUS improve diet, exercise, follow up, and self-efficacy at three months post-intervention? Researchers will compare an educational intervention with versus without POCUS to see if POCUS works to improve outcomes. Participants will: Receive either the educational intervention alone or an educational intervention plus POCUS. They will report the difference in their understanding and likelihood to improve diet, exercise, and follow up immediately post-intervention. They will also report changes in diet, exercise, follow up, and self-efficacy at three months post-intervention.
The ENGAGE-HF mobile application tracks three key features over time: (1) heart failure health status, (2) vital signs (e.g., blood pressure, heart rate) and weight, and (3) the quality of heart failure medication therapy. Helping patients understand how these characteristics interact and change over time may improve their ability to understand and manage heart failure. In this study, the investigators aim to evaluate whether the ENGAGE-HF mobile application, by facilitating the behavior change strategies of self-monitoring and feedback, and a clinician-facing dashboard, improves the optimization of heart failure guideline-directed medical therapies (GDMT) and quality of life. An optional sub-study of cognitive function will invite all eligible participants enrolled in the main study to participate.
The purpose of this study is to find out if the investigational drug called omecamtiv mecarbil can reduce the risk of the effects of heart failure, like hospitalization, transplantation, or death in patients with heart failure and severely reduced ejection fraction.
Heart failure (HF) affects more than 6 million adults in the U.S. alone, with increasing prevalence. Cardiovascular congestion with resultant limitation in physical activity is the hallmark of chronic and decompensated HF. The current HF physiologic model suggests that congestion is the result of volume retention and, therefore, therapies (such as diuretics) have generally been targeted at volume overload. Yet therapeutic approaches to reduce congestion have failed to show significant benefit on clinical outcomes, potentially due to an untargeted approach of decongestive therapies. The investigators' preliminary work suggested a complimentary contribution of volume redistribution to the mechanism of cardiac decompensation. The investigators identified the splanchnic nerves as a potential therapeutic target and showed that short-term interruption of the splanchnic nerve signaling could have favorable effects on cardiovascular hemodynamics and symptoms. As part of the investigators' proposal, the investigators will test the safety and efficacy of prolonged splanchnic nerve block in a randomized, controlled, blinded study in patients with HF and reduced ejection fraction (HFrEF). The results will help test the hypothesis of volume redistribution as a driver of cardiovascular congestion and functional limitations and pave the way for splanchnic nerve blockade as a novel therapeutic approach to HF.
