Recruiting studies
- NCT05013944Recruiting
Join a patient registry to support future research
This trial is a “patient registry,” which collects health information over time to help researchers plan and run future studies. It may help by contributing your experience so new treatments can be tested more effectively.
Arlington Heights, IllinoisAges 18 years+ - NCT06445608Recruiting
Study of a heart pump for high-risk angioplasty
This trial tests a temporary heart pump (called the KARDION Cory P4) used during a high-risk angioplasty (stenting) procedure. The pump helps keep blood flowing in patients whose heart is weak or who have complex blockages, aiming to make the procedure safer.
Chandler, ArizonaAges 18–90 - NCT07447297Recruiting
Early Rhythm Control for Device-Detected Fast Heart Episodes
This trial tests whether starting treatment early to control your heart's rhythm can help people with a heart device who have short bursts of a fast heartbeat (called atrial high rate episodes) but haven't yet been diagnosed with atrial fibrillation on a standard EKG or Holter monitor.
Seoul, SeoulAges 19 years+ - NCT06310031Recruiting
Testing BrioVAD heart pump for severe heart failure
This trial tests a new left-ventricular assist device (LVAD) called BrioVAD for people with advanced heart failure who are not getting enough benefit from medicines. If you qualify, the device is implanted to help your heart pump blood.
Birmingham, AlabamaAges 18–100 - NCT04289142RecruitingPhase 4
Testing memory effects of dexmedetomidine during heart surgery
This study looks at how a sleep medicine called dexmedetomidine affects thinking and memory after heart surgery. It compares cognitive outcomes over time to see if this sedation choice changes long-term brain function.
Vancouver, British ColumbiaAges 60 years+ - NCT06526195Recruiting
A study of CardioMEMS and HeartMate 3 for advanced heart failure
This trial tests if a combination of a tiny lung-artery pressure sensor (CardioMEMS) and a mechanical heart pump (HeartMate 3) is safe and effective for people with advanced heart failure. If you qualify, you'll either get the heart pump plus standard medical therapy, or continue with standard therapy alone and have your pressure monitored remotely.
Phoenix, ArizonaAges 18 years+ - NCT07691307Recruiting
TruGamma tricuspid valve replacement study
This trial tests a new device called TruGamma to replace the tricuspid valve without open-heart surgery. It is for older adults with severe tricuspid regurgitation who cannot have surgery and still have symptoms despite medication.
Beijing, Beijing MunicipalityAges 65 years+ - NCT07296744Recruiting
Study of a heart pump for high-risk angioplasty
This trial tests a new device called the Supira system to support the heart during a high-risk procedure to open blocked arteries. It is for people who are stable enough to wait for the procedure (not in emergency or shock).
Loma Linda, CaliforniaAges 18–90 - NCT05610787Enrolling by invitation
Testing a device that helps move an EXCOR pediatric heart pump
This trial studies an “active driving” system that controls the EXCOR pediatric heart pump. It’s meant for children who need a heart pump as a bridge to heart transplantation, to help the pump work more safely and effectively.
Los Angeles, CaliforniaAges Up to 21 years - NCT05443425RecruitingPhase 1
Leflunomide plus steroids for acute graft-versus-host disease
This early-phase trial tests whether adding leflunomide to standard steroid treatment can better control acute graft-versus-host disease (aGvHD) after a stem cell transplant. It may help reduce the immune reaction that damages the body while keeping treatment safe and manageable.
Duarte, CaliforniaAges 18 years+ - NCT07380217Recruiting
Using heart pump support for complex high-risk procedures
This trial is testing whether using a special heart pump (PulseCath iVAC2L) during complex, high-risk angioplasty can help people with very weak hearts. It's for people who need a procedure for complicated coronary artery blockages.
AmsterdamAges 18 years+ - NCT07276711Recruiting
Protecting brain during TAVR with EmStop device
This trial tests a new device (EmStop) that helps protect your brain during TAVR (a type of heart valve replacement). The device is placed in arteries to catch any debris that might break loose during the procedure, potentially reducing the risk of stroke.
New Orleans, LouisianaAges 22 years+ - NCT07094919Recruiting
Corheart 6 heart pump long-term study
This study follows people who have already received the Corheart 6 heart pump to see how well it works over time. You may qualify if you have severe heart failure that doesn't improve with standard treatments and you got the pump after October 1, 2021.
Shenzhen, GuangdongAges 18 years+ - NCT07130994Recruiting
Testing a new less invasive mitral valve replacement (SATURN)
This trial tests a new, less invasive device called the SATURN system to replace a severely leaky mitral heart valve without open-heart surgery. It is for people who are too high-risk for traditional surgery and are willing to take blood thinners.
Los Angeles, CaliforniaAges 18 years+ - NCT06455787Recruiting
J-Valve study for leaky aortic valve patients
This study tests a new, less invasive device called J-Valve for people with severe aortic regurgitation (a leaky aortic valve). It is placed through a tube in the leg artery, avoiding open-heart surgery, and may help those who are at high risk for surgery.
Scottsdale, ArizonaAges 18 years+ - NCT07363538Recruiting
Comparing heart surgery methods for newborns with complex heart defects
This trial tests new surgical strategies for newborns with certain complex heart conditions. It aims to see which techniques lead to better recovery and quality of life in the first year after surgery.
Beijing, Beijing MunicipalityAges Up to 1 week - NCT07045064Recruiting
Exercise during dialysis for heart health
This study compares two types of exercise (aerobic vs. resistance training) done during hemodialysis sessions, and looks at how they affect a blood test related to heart disease risk.
Cairo, Select StateAges 40–60 - NCT05927233RecruitingPhase 4
Methylprednisolone in children after open-heart surgery
This trial tests whether giving methylprednisolone (a steroid medicine) can lower the body’s inflammatory response in children during the first day after congenital open-heart surgery. It may help reduce harmful inflammation and improve recovery for some children undergoing their first surgery.
Karachi, SindhAges 1 month–18 years - NCT06930521Recruiting
Monitoring heart health during HER2 therapy for breast cancer
This study tracks how well the heart handles HER2-targeted therapy (like Herceptin) during the first year of treatment for early-stage breast cancer. It helps keep you safe by checking heart function closely.
Toronto, OntarioAges 18–79 - NCT04842006Recruiting
Personalized treatment plan for rectal cancer before and after surgery
This trial looks at a personalized treatment approach for rectal cancer. It aims to guide the best chemotherapy and (if needed) radiotherapy before and after surgery, based on scans and specific test results.
Helsinki, UusimaaAges 18–100

Common questions
- Are there clinical trials for diseases of the circulatory system?
- Yes. Clin2 currently lists 20 recruiting diseases of the circulatory system 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 diseases of the circulatory system 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 diseases of the circulatory system 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.
