Symptomatic heart failure

This study tests a device called Barostim that stimulates nerves in the neck to help the heart work better. It involves 2,500 adults with moderate heart failure who still have symptoms despite standard treatments. The goal is to see if the device reduces deaths and hospital stays…

This trial tests whether a digital tool that prompts doctors to adjust heart failure medications can improve care. The tool uses home monitoring and patient data to suggest medication changes. The study includes over 1,300 adults with heart failure and will measure hospitalizatio…

This study tests a small sensor implanted in the lung artery that sends daily pressure readings to doctors. It involves 81 adults with advanced heart failure (NYHA Class III). The goal is to see if the device is safe and accurate, helping patients avoid hospital stays by catching…

This study tested a small sensor placed in the lung artery to help doctors monitor heart failure patients remotely. 738 people with advanced (NYHA Class III) heart failure took part. The goal was to see if using the sensor could reduce hospitalizations and deaths compared to a ta…

This study tests an investigational drug called COR-1167 in 300 people hospitalized with worsening heart failure. Participants receive either the drug or a placebo for 28 days. Researchers measure how well the body removes fluid, changes in weight, heart function, and symptoms. T…

This study follows 2,500 people with moderate heart failure (NYHA Class II or III) who already have a CardioMEMS sensor implanted in their lung artery. The sensor wirelessly sends pressure readings to doctors, who use the data to adjust medications. Researchers will track surviva…

This study tests whether a mechanical heart pump called the HeartMate III (an LVAD) helps people with end-stage heart failure live longer and with fewer strokes compared to taking standard heart failure medications. About 80 adults with severe heart failure are randomly assigned …

This study tests whether hearts from donors who died from circulatory death (DCD) are as safe for transplant as hearts from brain-dead donors (DBD). About 40 adult heart transplant recipients will receive either a DCD or DBD heart. The goal is to see if using DCD hearts can safel…

This study looks at whether doing a preventive heart ablation (a procedure to destroy small areas of heart tissue causing irregular rhythms) before LVAD surgery can reduce serious problems like dangerous heart rhythms, death, blood clots, or heart failure in the first 30 days aft…

This study tests whether a bedside device called Quantra can help doctors decide when to give blood transfusions during complex heart surgery. The device measures how well a patient's blood clots in real time. Researchers hope this will reduce the number of blood products (like r…

This study is testing the Carmat Total Artificial Heart in 104 people with severe, irreversible heart failure who are waiting for a heart transplant. The device is designed to replace both heart chambers and keep patients alive until a donor heart becomes available. Researchers a…

This study compares a new heart pump (EVAHEART®2) to a current pump in 399 adults with severe heart failure. The goal is to see if the new pump helps people survive until a heart transplant or recover enough to have the pump removed, without suffering a disabling stroke or severe…

This study tests whether injecting lab-grown heart muscle cells (HiCM-188) into the heart during bypass surgery can safely help people with severe chronic heart failure. About 36 adults with damaged heart tissue and reduced pumping function will receive the cell injection. The ma…

This trial is testing a new mechanical heart pump called the Corheart 6 in 50 people with end-stage heart failure. The pump is implanted to help the heart circulate blood. Researchers are checking if the device works safely and effectively at 3 months and 2 years after implantati…

This study tests a one-time gene therapy called AB-1002, given directly into the heart arteries, for people with advanced heart failure (NYHA Class III). The goal is to see if it can improve heart function, reduce symptoms, and lower the risk of death or hospitalization. About 15…

This registry follows 350 adult heart transplant patients whose donor hearts were kept alive and beating using the OCS Heart System before transplant. The goal is to see how well patients do one year after surgery. The device may allow more donor hearts to be used, especially tho…

This study looks at whether existing blood markers can accurately identify the underlying cause of heart failure in 511 patients. Researchers aim to improve diagnosis and potentially reduce healthcare costs by avoiding unnecessary tests. Participants were recently diagnosed with …

This early study tests a device that creates a small, temporary opening in the wall of the heart to relieve pressure and improve symptoms in people with advanced heart failure. The main goal is to see if the procedure is safe. About 20 participants who have not responded well to …

This study tests two treatments—blood flow restricted resistance exercises and low-level laser therapy—to see if they improve heart function in people with chronic heart failure. Sixty patients aged 40-60 with mild heart failure will be assigned to one of the treatments for 12 we…

This study tests new strategies to make sure that decisions about who gets a heart transplant or a heart pump are fair and based on objective medical criteria, not bias. Researchers will work with over 1,400 patients and doctors at heart centers across the U.S. to reduce racial a…

This study looks at whether a quick, simple test—standing up and sitting down from a chair as many times as possible in one minute—can help predict how heart failure patients will fare after leaving the hospital. Researchers will follow 68 adults hospitalized for decompensated he…

This study looks at how SGLT2 inhibitors, a type of diabetes drug also used for heart failure, affect the body's metabolism. About 40 adults with mild to moderate heart failure will have blood tests, walking tests, and calf MRIs before and after starting the medication. The goal …

This study looks at medical records from over 600 Indian adults with chronic heart failure who were prescribed vericiguat between 2022 and 2023. Researchers want to see how the drug is used in routine care, how well it works, and what side effects occur. No new tests or visits ar…

This study looks at 120 adults getting a left ventricular assist device (LVAD) to see how often infections happen and how their immune system changes after surgery. The goal is to find what makes some patients more likely to get infections. This research does not test a new treat…
