Recruiting studies
- NCT05568069Recruiting
Study of defibrillator implants for non-ischemic weak heart
This study looks at whether implantable defibrillators can reduce dangerous heart rhythms in people with non-ischemic cardiomyopathy (heart weakness not caused by blocked heart arteries), a heart scar, and very low pumping strength despite best treatment. It compares different approaches to choosing which patients should receive these devices.
High Wycombe, BuckinghamshireAges 18 years+ - NCT07050706Enrolling by invitation
Heart failure and protein levels in the blood
This trial checks if a protein called PRMT5 in the blood is linked to heart function in people with heart failure. It compares healthy volunteers and those with heart failure to see if this protein can help understand the condition better.
Shenzhen, GuangdongAges 18 years+ - NCT06652087Recruiting
Testing rifaximin for heart failure with preserved pumping
This trial tests whether the antibiotic rifaximin (taken by mouth) can improve heart function in people with a type of heart failure where the heart pumps well but is still weak (HFpEF). Rifaximin might help by changing the bacteria in your gut.
MoscowAges 18–80 - 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 - NCT07617376RecruitingPhase 4
Flu shot before leaving hospital after heart problems
This study tests whether giving a flu vaccine to patients before they leave the hospital after a heart condition improves their health. The vaccine may help protect your heart and prevent serious flu complications while you recover.
WroclawAges 18 years+ - NCT06689111Recruiting
Heart resynchronization method study for patients with LBBB and heart failure
This study compares two ways to resynchronize the heart's pumping in people with heart failure and a specific heart block (LBBB). It uses special ultrasound imaging to see which method works better for improving heart function.
Pátrai, GreeceAges 18–90 - 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+ - NCT05972356Recruiting
How heart relaxation affects outcomes in heart surgery
This study looks at whether a measurement of how well the heart relaxes helps predict outcomes after heart surgery. It focuses on patients treated in Amsterdam UMC and uses care data to understand who may be at higher or lower risk.
Amsterdam, North HollandAges 18 years+ - NCT06179329Recruiting
Comparing two types of heart bypass grafts in women
This trial compares two types of grafts (the radial artery from the arm and a vein from the leg) used in women having heart bypass surgery for the first time. It aims to see which graft works better and stays open longer.
São Paulo, São PauloAges 18–75 - NCT06620523RecruitingPhase 2
Preventing kidney injury after heart bypass surgery
This trial tests whether combining two natural supplements (CoQ10 and glutathione) can protect your kidneys during heart bypass surgery. It may help prevent acute kidney injury, a common complication after these procedures.
Washington D.C., District of ColumbiaAges 18–70 - NCT06954103Recruiting
Stroke and heart health study for recent stroke patients
This study looks at how a moderate to severe stroke can affect your heart. It aims to understand the link between stroke and heart problems, which may help improve future care.
Wuhan, HubeiAges 18 years+ - NCT00271180Recruiting
Tracks long-term performance of Medtronic heart devices
This study follows how well certain Medtronic heart devices work over the long term. You may be included if you have a qualifying Medtronic implant and the research team can reliably get your implant and follow-up information.
Birmingham, AlabamaAges Any age - NCT07158450Enrolling by invitation
Heart health check for cancer patients
This trial tests a new device that monitors heart health during cancer treatment. It uses a simple on-body sensor alongside your regular echocardiogram to see if it can detect heart changes early.
Golden, ColoradoAges 18 years+ - NCT05604430Enrolling by invitation
Study of pre-hospital breathing support with a specific ventilator
This study looks at breathing support given outside the hospital using a particular ZOLL ventilator model and software version. If you were treated with the right equipment, the team will use the ventilator’s recorded data to evaluate how ventilation was delivered.
Baton Rouge, LouisianaAges Any age - NCT07393009Recruiting
Study of a new left bundle branch area pacing system
This study tests a new type of pacemaker system that delivers pacing to the left side of the heart through a lead placed deep in the wall between the lower chambers. The goal is to see if this approach works well for people who need a pacemaker or CRT.
AdelaideAges 18 years+ - NCT05479669Recruiting
Testing detailed heart scans in people with heart failure symptoms
This study looks at whether doing very detailed heart testing helps understand and guide care for people with heart failure with preserved pumping strength. You may be eligible if you’re an adult with specific symptom levels, recent heart-failure-related visits, and matching scan and blood test results.
GroningenAges 18 years+ - NCT06423599RecruitingPhase 2/Phase 3
Weight Loss for Obesity and Heart Failure
This study tests whether weight loss from a medication can improve how you feel, move, and how well your heart works. It's for people who have both obesity and heart failure with reduced pumping strength.
CopenhagenAges 18 years+ - NCT06699056Recruiting
AI heart monitor study for ejection fraction
This study uses an AI-powered wearable monitor to check how well your heart pumps blood (ejection fraction) from a simple EKG recording. It may help doctors quickly assess heart function without extra tests.
Orange, CaliforniaAges 18 years+ - NCT06868797Recruiting
Dapagliflozin for advanced heart failure patients waiting for transplant
This study tests whether dapagliflozin (a medicine already approved for other heart conditions) can help protect kidney and heart function in people with very advanced heart failure who are waiting for a heart transplant. If you qualify, you'll help researchers learn if this drug offers extra benefits beyond standard care.
BronAges 18 years+ - NCT06964464RecruitingPhase 4
Comparing two heart failure medications in ICD patients
This trial compares two beta-blocker medications, carvedilol and metoprolol succinate, to see which one works better for people with heart failure who have an implantable cardioverter defibrillator (ICD). If you are currently taking metoprolol succinate, you may be able to switch to carvedilol and help researchers find the best treatment.
Scottsdale, ArizonaAges 18 years+ - NCT05632432Recruiting
Heart tissue grafts to help the heart after surgery
This trial tests whether transplanting tiny heart “micrografts” from the left heart chamber area can improve heart function after cardiac surgery. It is meant for people with weakened heart pumping and heart failure symptoms despite medicine.
Helsinki, UusimaaAges 18–75 - NCT07636343Recruiting
Eccentric Training for Heart Failure Recovery
This trial tests a special type of strength training (eccentric exercise, where muscles lengthen under load) for people with heart failure who have reduced pumping ability. The goal is to improve your exercise capacity and heart function safely.

Common questions
- Are there clinical trials for cardiac failure?
- Yes. Clin2 currently lists 190 recruiting cardiac 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 cardiac 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 cardiac 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.
