Recruiting studies
- NCT05487612Recruiting
MiECC heart-lung machine vs standard bypass during heart surgery
This trial compares a newer heart-lung machine setup (MiECC) with the usual bypass technique during certain heart operations. It may help see whether MiECC changes outcomes like the need for blood transfusions or recovery after surgery.
TorontoAges 18–85 - NCT05014802Recruiting
MRI scans before heart surgery to predict post-surgery atrial fibrillation
This study uses an MRI scan before heart surgery to look for heart scarring that may predict who will develop atrial fibrillation afterward. Knowing the risk ahead of time could help doctors monitor you more closely and plan prevention.
Covington, LouisianaAges 40–120 - NCT04913649RecruitingPhase 4
IV iron for anemia after heart surgery in older adults
This trial tests whether giving iron through a vein after heart surgery helps treat postoperative anemia (low red blood cells) in people age 70 and older. It may improve recovery by correcting low iron levels after surgery.
BredaAges 70 years+ - NCT04299828Recruiting
Study of inflammation activity during complex heart surgery
This study measures how active white blood cells and inflammation are during complex heart surgery using a heart-lung machine. It may help doctors better understand what triggers inflammation during surgery and how to improve care.
Boston, MassachusettsAges Any age - NCT04707794Recruiting
Preventing confusion after non-heart surgery in older adults
This study looks at how often older adults develop sudden confusion (delirium) after non-heart operations under general anesthesia. It may help doctors better predict who is at risk and improve care after surgery.
New Delhi, National Capital Territory of DelhiAges 65 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+ - NCT02573532Recruiting
Tracking heart damage after non-cardiac surgery
This study looks at whether patients experience heart muscle injury during or shortly after non-cardiac surgery. It aims to understand how common this is and what it means for recovery.
Basel, Canton of Basel-CityAges 45 years+ - NCT07208500Recruiting
Arm cuff treatment before surgery to protect lungs in older adults
This study tests if a simple, non-invasive treatment (briefly inflating a blood pressure cuff on your arm) before surgery can reduce lung complications in older adults having non-heart, non-lung surgery. It may help protect your lungs during and after the operation.
ShanghaiAges 65 years+ - NCT04915261RecruitingPhase 4
Lenient versus strict instructions after heart device surgery
This trial compares two styles of “post-surgery instructions” after implantation of a new heart device lead. It may help determine which approach is better for patients’ recovery and safety after the procedure.
Ottawa, OntarioAges Any age - NCT07304947Recruiting
Guiding blood flow during Moyamoya surgery in children
This study tests if careful monitoring and management of blood flow during surgery can help children with Moyamoya disease recover better after EDAS. It aims to improve safety and outcomes by adjusting treatment based on real-time heart function.
SeoulAges 1 month–18 years - NCT07483047Recruiting
Predicting memory changes after heart surgery in older adults
This study looks at older adults having heart surgery to find out who might have trouble thinking or remembering afterward. Researchers hope to build a tool to predict this risk so doctors can help sooner.
ShanghaiAges 65 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 - NCT07824700Recruiting
Prehabilitation for frail patients before heart surgery
This program helps mildly or moderately frail patients get physically stronger before their heart surgery or procedure. It is designed to improve recovery and outcomes by starting exercises and support during the waiting period.
Hong KongAges 18 years+ - NCT06986967Recruiting
Comparing Blood Flow Methods During Aortic Arch Surgery
This study compares two methods of supplying blood to the brain during surgery on the main artery from the heart (aorta) and the aortic arch. It may help determine the safest way to protect the brain during cooling and surgery.
Durham, North CarolinaAges 18 years+ - NCT06196307Recruiting
Early warning system for sudden chest pain
This trial is for people who come to the emergency room with new or worsening chest pain not caused by an injury. It aims to build an early warning system to better classify and treat chest pain.
Beijing, ChaoyangAges 18 years+ - NCT05934409Recruiting
Measuring body-fat storage after bariatric surgery
This study looks at how body fat is stored and how that may relate to early improvements in diabetes and heart/liver health after bariatric surgery. It may help researchers understand why some people recover faster and which body changes matter.
Sherbrooke, QuebecAges 18–65 - NCT06519747Recruiting
Detecting irregular heartbeat after non-heart surgery
This trial uses a monitoring device to check for a common but often overlooked irregular heartbeat (atrial fibrillation) after non-cardiac surgery. The goal is to detect and treat it early to prevent complications like stroke.
Hamilton, OntarioAges 18–120 - NCT06336213Recruiting
Using a blood test to guide antibiotics in aorta surgery
This trial checks if a blood test called presepsin can help doctors decide when to use antibiotics in patients having surgery on the chest's main artery (the thoracic aorta). It is for people with an aneurysm or tear in that artery.
Moscow, MoscowAges 18–75 - NCT07609680Recruiting
Blood Pressure vs. Heart Output Monitoring During Colon Surgery
This trial compares two ways doctors monitor your body's circulation during colorectal surgery. One method tracks blood pressure; the other tracks how much blood your heart pumps. Researchers want to see which approach leads to better outcomes and fewer complications.
Ankara, Yenimahalle\AnkaraAges 18–80 - NCT07603336Recruiting
Heart Monitoring Methods During Pancreas Surgery
This study compares two ways of monitoring your heart function during Whipple surgery (pancreas removal). Doctors will use different monitoring approaches to guide fluid and medication during your operation to help you recover better.
Çankaya, AnkaraAges 18–80 - NCT06739005Recruiting
AI model to assess heart surgeon technique in bypass surgery
This study tests whether an artificial intelligence (AI) model can accurately evaluate the surgical technique of heart surgeons performing a common bypass procedure. If you are a first-time bypass patient and do not have certain heart or organ conditions, you may be able to participate and help improve surgical training tools.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05094843Recruiting
Mini-invasive surgery for lung cancer and heart rhythm changes
This study looks at how lung cancer surgery affects the heart’s electrical signals and stress response, using heart tracing tests (ECG) around the time of surgery. It may help doctors better understand and monitor heart risks in people having curative, minimally invasive lung cancer surgery.
Tampere, PirkanmaaAges 18 years+ - NCT06336746Recruiting
Heart function during steep head-down position in robotic surgery
This study looks at how your heart performs during robotic surgery when you are placed in a steep head-down position. It may help doctors better understand how to keep you safe during the procedure.

Common questions
- Are there clinical trials for cardiac surgery?
- Yes. Clin2 currently lists 295 recruiting cardiac surgery 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 surgery 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 surgery 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.
