This study compares a heart procedure called catheter ablation to standard medical treatment for people with atrial fibrillation (an irregular heartbeat) and heart failure with preserved ejection fraction (a type of heart failure where the heart pumps normally but is stiff). The …

This study tests whether the diabetes and weight-loss drug tirzepatide (Mounjaro) can reduce the chance of atrial fibrillation coming back after a heart procedure called catheter ablation. About 602 adults with obesity and a type of heart failure (HFpEF) will get either tirzepati…

This study tests whether transplanting healthy gut bacteria (fecal microbiota transplantation) can improve quality of life and exercise ability in elderly patients with a common type of heart failure (HFpEF). Fifty adults aged 60 and older will receive either the transplant or a …

This study tests a procedure called pulmonary artery denervation (PADN) for people with heart failure whose heart pumps normally but is stiff. The procedure uses a catheter to burn nerves in the lung artery, which may help the heart work better. About 310 participants will either…

This pilot study tests a special pacemaker-like device called Moderato Plus in 20 people with high blood pressure and a type of heart failure where the heart pumps normally but is too stiff (HFpEF). The device delivers Cardiac Neuromodulation Therapy to help control blood pressur…

This study tests whether the drug finerenone can reduce scarring in the heart muscle and improve heart structure and function in people with heart failure. About 104 adults with mild to moderate heart failure will receive either finerenone or a placebo for 6 months. The main goal…

This study tests whether the drug finerenone can help people with heart failure who have had a heart valve replacement (TAVI). About 2,800 older adults will be randomly assigned to receive finerenone or a placebo. The goal is to see if the drug lowers the chance of death or worse…

This study will test whether tirzepatide (Mounjaro), a drug used for diabetes and weight loss, can help people with obesity-related heart failure with preserved ejection fraction (HFpEF). Researchers will measure changes in blood volume and body fat in 50 participants over 15 mon…

This study tests whether quickly starting and increasing guideline-recommended heart failure medications after hospitalization improves outcomes in women. About 360 women from 13 Italian hospitals will be randomly assigned to either a high-intensity care group (rapid drug optimiz…

This study tests a new adjustable cooler for storing donor hearts during transport to the transplant hospital. The cooler aims to keep the heart at a steady temperature, reduce waste, and lower costs compared to the current standard device. About 80 adults receiving a heart trans…

This study tests whether the drug sacubitril/valsartan can reduce scarring in the heart muscle of people with a type of heart failure called HFpEF (stiff heart). The trial will enroll 36 adults aged 50 and older with heart failure and a normal pumping function. Participants will …

This study tests whether an artificial intelligence (AI) program can help doctors identify a rare heart condition called cardiac amyloidosis on routine echocardiograms. The condition causes protein buildup in the heart muscle, leading to heart failure, and is often missed early o…

This study tests whether a new risk algorithm (FIND HF) can better detect undiagnosed heart failure in people at risk. About 475 adults aged 40+ will have a blood test and heart ultrasound. Researchers will compare how many high-risk vs low-risk people are found to have heart pro…

This study tests whether a 6-month digital education program—with short videos on exercise, healthy eating, and stress management—can improve exercise capacity and quality of life in adults with heart failure and overweight or obesity. Fifty-two participants will be randomly assi…

This study tests a new exercise approach for people aged 60 and older who have both atrial fibrillation (an irregular heartbeat) and a type of heart failure called HFpEF. Instead of starting with aerobic exercise like walking, participants will first do 2 months of progressive re…

This study looks at how the stiffness and function of blood vessels change in people newly diagnosed with heart failure. Researchers will measure these factors at the start, after a few weeks of standard medication, and after a cardiac rehab program. All tests are non-invasive an…

This study follows 500 people with a type of heart failure called HFpEF, where the heart pumps normally but doesn't fill properly. Researchers will use heart ultrasounds, blood tests, and medical history to group patients into different subtypes. The goal is to better understand …

This study will look at medical records from over 2 million adults who had surgery in Sweden between 2021 and 2024. Researchers want to see how common heart failure is in surgical patients and whether it raises the risk of death or other problems after surgery. The goal is to bet…

This observational study will follow 150 adults with obesity who are already scheduled for bariatric surgery. Researchers will use CT scans and echocardiograms before and about 6 months after surgery to measure fat inside the heart muscle and check how well the heart relaxes. The…

This observational study will enroll 30,000 adults in Denmark to better understand heart failure with preserved ejection fraction (HFpEF), a condition where the heart pumps normally but is too stiff to fill properly. Researchers will use blood tests, heart imaging, and health rec…
