Supira heart support device for high-risk artery stenting
This trial tests a new device (the Supira system) that helps support your heart's pumping function during and after a high-risk procedure to open blocked coronary arteries. It is for people with heart failure and complex blockages who may need extra circulatory support.
Tbilisi, K'alak'i T'bilisiAges 18–90 - NCT07083557Recruiting
Validation study for lab tests on hormones and metabolism
This study checks if lab tests used for hormone, heart, metabolism, and muscle disorders are accurate and reliable. You might be eligible if you are an adult with a body mass index between 16 and 60.
Columbia, MissouriAges 18–100 - NCT06332391Recruiting
Paced heart rate increase for heart conditioning
This trial tests whether a special pacing pattern can strengthen your heart's pumping ability. You may qualify if you have heart failure with a low ejection fraction and already have a pacemaker or defibrillator with an atrial lead.
Iowa City, IowaAges 18–120 - NCT05451979Recruiting
Exercise training at home for kids after heart transplant
This trial tests a home-based, short bursts exercise program (HIIT using the MedBIKE™ system) for children who had a heart transplant at least 6 months ago. It may help improve fitness and safety after transplant, while checking which kids can participate without heart rhythm or symptom problems.

Training to improve how advanced heart failure therapies are chosen
This study tests a program that helps care teams make more consistent, fair decisions about advanced heart failure treatments like heart transplants and mechanical heart pumps. It focuses on how professionals are trained and evaluated, not on patients receiving a new medicine.
Indianapolis, IndianaAges 18 years+ - NCT00762333Recruiting
Blood tests after a heart attack to study heart strain markers
This study looks at blood test “markers” soon after an acute heart attack, to better understand heart damage and whether heart failure is present. It may help doctors improve how they monitor recovery and risk in people after a heart attack.
Farmington, ConnecticutAges 18 years+ - NCT04973579Recruiting
Stent plus heart surgery for high risk carotid patients
This trial looks at whether doing carotid artery stenting at the same time as heart surgery is safe and effective for people at high risk of stroke around the time of surgery. It targets people with significant carotid narrowing who also need heart surgery for specific heart problems.
KrakowAges 18 years+ - NCT04158479Recruiting
Registry for people on ECMO life support
This registry collects information about people who are placed on ECMO, a heart-lung machine used to support breathing and/or circulation. It may help doctors better understand who benefits and how to manage ECMO in the future.
Beijing, Beijing MunicipalityAges Any age - NCT05841199Recruiting
Study heart blood flow during fast heart rates
This study measures how well blood flows through the heart when the heart rate is increased during a heart procedure. It may help doctors better understand coronary (heart artery) blood flow and how to guide treatment when you need angiography or angioplasty.
LondonAges 18 years+ - NCT06570473RecruitingPhase 2
RV failure treatment trial for pulmonary hypertension patients
This trial is testing two heart medications, empagliflozin and ranolazine, to see if they can improve right heart function in people with pulmonary hypertension and right ventricular failure. Participants will monitor their symptoms using a smartphone or tablet.
Calgary, AlbertaAges 18 years+ - NCT06218199RecruitingPhase 4
Diuretics vs. blood pressure meds for HeartLogic alerts
This trial compares two treatments—diuretics (water pills) and a blood pressure medication called sacubitril/valsartan—to see which works better when your heart device sends an alert. It's for people with a Boston Scientific heart device that has HeartLogic alerting turned on.
Huntsville, AlabamaAges 19 years+ - NCT06764225Recruiting
Low-Sodium Salt for Heart Failure Patients
This study tests whether using a low-sodium salt substitute can help people with heart failure live longer, avoid hospital visits, and feel better. It's for adults with a weakened heart pump who have a caregiver and eat home-cooked meals.
Beijing, Beijing MunicipalityAges 18–75 - NCT06409585Recruiting
Heart muscle disease imaging study for scarring
This study uses advanced imaging (PET/MR or PET/CT) to look at scarring (fibrosis) in the heart muscle. It is for people with various heart muscle diseases, including heart failure with preserved pumping, thickened heart muscle, high blood pressure-related heart damage, heart inflammation, and others.
Edinburgh, ScotlandAges 30–90 - NCT07099859RecruitingPhase 4
Losartan after aortic valve surgery for severe leakage
This trial tests if the drug losartan can help the heart recover better after surgery to replace a leaky aortic valve. It may reduce strain on the heart and improve long-term outcomes.
São Paulo, São PauloAges 18–85 - NCT06587165Recruiting
Measuring new heart cells in babies having heart surgery
This study looks at how the heart makes new muscle cells in babies under 1 year old who need heart surgery. Tissue that is normally removed during surgery will be studied to learn more about heart repair.
New York, New YorkAges 4 weeks–1 year - NCT03945968Recruiting
Risk scores after abdominal surgery for people with health conditions
This study looks at how other health problems affect the chance of postoperative complications after abdominal surgery. It aims to help doctors better predict risk and decide on the safest care for you.
ArkhangelskAges 18 years+ - NCT07131631Recruiting
MitraClip for leaky heart valve in heart failure patients
This trial tests if the MitraClip device helps people with heart failure and a leaky mitral valve. It uses a special MRI to check how the heart responds to treatment.
Minneapolis, MinnesotaAges 18 years+ - NCT05450328RecruitingPhase 2
Breathing medicine to help heart-lung machine separation after surgery
This Phase 2 trial tests whether inhaled medicines (milrinone and epoprostenol) can make it easier to separate from the heart-lung machine during cardiac surgery. It may help reduce the risk of a difficult transition off the machine for the right patients.
Montreal, QuebecAges 18 years+ - NCT05443321Enrolling by invitation
Health information sharing during hospital transfers
This trial studies whether sharing patients’ health information between hospitals during transfers can improve outcomes. You may be included if you are moved from a specific partner hospital to Brigham and Women’s Hospital and admitted to certain hospital units.

Heart registry for adults with heart failure, CAD, or atrial fibrillation
This is a hospital-based study that collects standardized information about adults with specific heart conditions—heart failure, coronary artery disease, or atrial fibrillation. It may help doctors and researchers better understand these diseases and improve future care.
BerlinAges 18 years+ - NCT07491237Recruiting

This study looks at how heart rhythm problems affect heart function. It may help doctors better understand and treat these conditions.
RomaAges 18 years+ - NCT06595147Recruiting
Exercise for heart health in breast cancer survivors

Common questions
- Are there clinical trials for heart failure?
- Yes. Clin2 currently lists 949 recruiting heart failure studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a heart failure trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a heart failure trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
