Recruiting studies
- NCT07278661RecruitingPhase 2

This trial tests if giving romiplostim before heart surgery can safely increase low platelet counts. It may help patients with low platelets avoid bleeding complications during and after surgery.
AngersAges 18 years+ - NCT07308847Recruiting
Study of a new catheter system for treating atrial fibrillation
This trial tests a new catheter and mapping system designed to treat paroxysmal atrial fibrillation (AF), which is a type of irregular heartbeat that comes and goes. If you have this condition, the study aims to see how well the new system works with a minimally invasive procedure.
Jonesboro, ArkansasAges 18–80 - NCT07664189Enrolling by invitation
Left bundle pacing plus CRT vs. LBBP alone
This trial tests a new pacing approach that combines a left bundle branch pacemaker with standard cardiac resynchronization therapy (CRT) for people with heart failure. It aims to improve the heart's pumping efficiency compared to using the left bundle branch pacemaker alone.
Medellín, AntioquiaAges 18 years+ - NCT05423158Recruiting

This study tests if virtual coaching can help more veterans attend cardiac rehabilitation at home. It is for veterans with heart conditions who have been referred to home-based cardiac rehab.
San Francisco, CaliforniaAges 21 years+ - NCT07560306RecruitingPhase 3
New Heart Scan to Detect Blood Clots in Amyloid Heart Disease
This study tests a new type of imaging scan ([64Cu]FBP8 PET) to detect blood clots that may form in the heart's left atrial appendage (a small pouch in the heart) in patients with amyloid cardiomyopathy (a disease where abnormal protein builds up in heart muscle) who also have irregular heartbeat. The scan may help doctors catch clots earlier and prevent strokes.
Boston, MassachusettsAges 18 years+ - NCT06907849Enrolling by invitationPhase 2
Imaging amyloid in spinal stenosis and carpal tunnel
This trial tests a special scan that uses a radioactive tracer to look for amyloid protein deposits in people who have had surgery for lumbar spinal stenosis (narrowing of the spine in the lower back) or carpal tunnel syndrome. The goal is to see if the scan can detect these deposits, which may be linked to ongoing orthopedic issues.
Knoxville, TennesseeAges 60 years+ - NCT07388355Recruiting
Ease of use study for a new heart monitor device
This study tests how easy it is to use a new device that records your heart's electrical activity through a simple patch on your chest. You will need to use a smartphone app with the patch.
New London, North CarolinaAges 18 years+ - NCT07711821Recruiting
Heart failure screening in primary care for older adults
This trial is testing a simple screening tool to find early signs of heart failure in people aged 50 or older, especially those with risk factors like diabetes or high blood pressure. If you're at risk, this could help catch heart problems sooner.
AmadoraAges 49 years+ - NCT01524276Recruiting
Registry to track outcomes of Medtronic medical devices
This is a follow-up registry that collects information from people who have (or will receive) an eligible Medtronic device. It helps the company and doctors better understand how the device works in real-world use.
Birmingham, AlabamaAges Any age - NCT04984473Recruiting
Breathing muscle training during heart rehab
This study tests whether breathing muscle training, added to regular heart rehab, can improve how well people with heart failure do day-to-day. It also compares results with healthy volunteers who do not have certain health problems.
Rochester, MinnesotaAges 18 years+ - NCT06471036Recruiting
Improving cholesterol testing and treatment after a heart attack
This study tests whether giving extra education to doctors and patients can help improve cholesterol management after a heart-related hospitalization. It aims to see if a simple program can make sure patients get the right testing and treatment for high cholesterol.
Minneapolis, MinnesotaAges 18 years+ - NCT03837574Recruiting
Registry for people with Tetralogy of Fallot and a defibrillator
This is a national registry that collects information about people with Tetralogy of Fallot who have an implantable defibrillator. It helps researchers better understand outcomes and care needs in this specific group.
ParisAges 18 years+ - NCT03302195Recruiting
Heparin and bypass blood management for obese heart surgery
This trial studies the best way to manage blood thinning (anticoagulation) during heart surgery that uses a heart-lung machine in people with obesity. It may help reduce blood-clotting and bleeding complications by comparing different care strategies.
Québec, QuebecAges 18 years+ - NCT03418961RecruitingPhase 3
Study of heart-risk management for metastatic HER2 breast cancer
This trial follows people with metastatic HER2-positive breast cancer who are at higher risk for heart damage while on HER2-targeted therapy. Some participants are randomly assigned to different monitoring/heart-protection approaches to see what best helps keep the heart safe.
Anchorage, AlaskaAges 18 years+ - NCT03446326Recruiting
Check how your pacemaker changes heart pumping
This study measures how well the heart pumps at different heart rates in people with pacemakers or defibrillators. It may help doctors understand how pacing settings affect heart function.
Calgary, AlbertaAges 18–70 - NCT03470246Recruiting
Wearable activity coaching after heart surgery
This study tests a personalized activity program and coaching after heart surgery, using wearable sensors to track movement. It may help you recover more safely and move in a goal-directed way during rehabilitation.
KuopioAges 30–90 - NCT03504956Recruiting
MRI study to map early heart artery plaque changes
This study uses an MRI scan to better “see and measure” early changes in the heart’s artery lining. It may help researchers understand coronary artery disease earlier, even before it causes symptoms.
Los Angeles, CaliforniaAges 18 years+ - NCT03546374Recruiting
Stop a common heart rhythm with surgery add-on therapy
This study looks at whether an added heart device approach around the time of planned open-heart surgery can help treat non-paroxysmal atrial fibrillation (AF), a long-lasting irregular heartbeat. It may help lower ongoing AF burden in people who also need non-emergency heart surgery.
Palo Alto, CaliforniaAges 18 years+ - NCT03729232Recruiting
Japanese registry for people who had catheter ablation
This is a national registry that collects health information from people in Japan who received catheter ablation. It may help doctors and researchers understand outcomes and improve future care.
Suita, OsakaAges Any age - NCT03793257Recruiting

This is a research registry for adults who need a breathing and/or heart support machine called ECMO while in the hospital. It collects information to better understand who receives ECMO and how patients do over time.
Canberra, Australian Capital TerritoryAges 18 years+ - NCT03858777Recruiting
Blood test for heart inflammation in sarcoidosis
This study checks whether a blood “cell-free DNA” test can show when the heart is inflamed in people with cardiac sarcoidosis. It may help doctors detect active heart involvement earlier and track how disease is doing.
Iowa City, IowaAges 18 years+ - NCT03992560Recruiting
Cardiac MRI-guided device implantation versus standard CRT
This trial compares two ways of placing a heart rhythm device: guiding the procedure with a cardiac MRI versus using the usual approach. It aims to see which method improves heart function and outcomes for people with a certain type of heart failure due to blocked heart arteries.
LondonAges 18 years+ - NCT07703033Recruiting
Heart Impact Study for Breast Cancer Radiotherapy
This study looks at how information about the heart may affect treatment decisions for people receiving radiation therapy for breast cancer. It aims to help reduce heart-related side effects from treatment.

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,308 recruiting cardiac 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 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 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.
