Recruiting studies
- NCT06885268RecruitingPhase 3

BernAges 45 years+ - NCT05812248Recruiting
Tracking heart and blood vessel events after major non-heart surgery
This study follows people after major surgery to see what predicts heart and blood vessel problems later. It does not test a new drug; it mainly collects health information to help clinicians reduce risk.
Guangzhou, GuangdongAges 45 years+ - NCT07472296Recruiting
Comparing nerve blocks for heart surgery pain relief
This trial compares different types of nerve blocks to see which works best for managing pain after heart surgery through the breastbone. It may help reduce the need for strong pain medications.
Bursa, NilüferAges 18–80 - NCT07385092Recruiting

This trial compares continuous vital sign monitoring with standard spot checks for patients recovering from non-cardiac surgery. It aims to see if constant monitoring can improve safety and outcomes.
Hamburg, Free and Hanseatic City of HamburgAges 45 years+ - NCT07052461Recruiting
Blood flow study in ICU patients after heart surgery
This study looks at blood flow patterns in patients after non-emergency heart surgery to see if they relate to recovery in the ICU. It uses a special ultrasound to check blood vessels in the belly and leg.
BaselAges 18 years+ - NCT07205393Recruiting
Heart rehab after valve replacement surgery
This trial tests a phase one cardiac rehabilitation program for people who have had their mitral or aortic heart valve replaced. It aims to see if the rehab helps recovery. You might qualify if you had planned (not emergency) valve surgery and are stable enough for light exercise.
QinaAges 40–55 - NCT07354841Recruiting
Testing safety of heart-lung machine tubes
This study tests two types of tubes used during heart surgery to connect you to a heart-lung machine. It aims to see if they work safely and effectively.
Bari, BAAges 18 years+ - NCT07634666Recruiting
Heart Safety Monitoring During Urologic Cancer Surgery
This study tracks heart health before and after major surgery for prostate or kidney cancer in older adults. Researchers want to predict which patients might experience heart problems after surgery so they can provide better care.
SeoulAges 60 years+ - NCT07391683Recruiting
Heart failure support before heart surgery
This trial tests if special remote care before heart surgery can improve recovery for people with heart failure. You will have regular check-ins by video or phone to help manage your health before your operation.
Innsbruck, TyrolAges 18 years+ - NCT07012668Recruiting
Treatments for heart-brain conditions and post-surgery stroke
This trial is studying different treatments for people who have conditions that affect both the heart and brain, or who have had a stroke or other brain blood vessel problem after heart surgery. The goal is to find out which treatments work best and see what factors affect the results.
BeijingAges 18 years+ - NCT06615102RecruitingPhase 3
Testing if angiotensin II prevents kidney injury after heart surgery
This trial tests whether giving a medicine called angiotensin II during heart surgery can help prevent acute kidney injury (a sudden drop in kidney function). It is for adults having certain types of heart surgery who have a higher risk of kidney problems.
BerlinAges 18 years+ - NCT07405333Recruiting
Coughing exercises vs breathing device after heart surgery in children
This study compares simple coughing exercises with a breathing device (incentive spirometry) to help children recover lung function faster after heart surgery. It may help reduce complications and shorten hospital stays.
Baghdad, Baghdad GovernorateAges 6–18 - NCT06381063RecruitingPhase 3
Anti-inflammatory for heart surgery
This trial is testing whether a non-steroidal anti-inflammatory drug (NSAID) given during heart surgery can reduce complications. It's for people having planned open-heart surgery with a heart-lung machine.
AmiensAges 18 years+ - NCT06066970Recruiting
Studying heart markers after valve surgery
This trial uses a special MRI and blood tests to see how heart muscle is affected after aortic or mitral valve surgery. It may help doctors better understand and monitor heart recovery.
Freiburg im Breisgau, Baden-WurttembergAges 18 years+ - NCT07232277Recruiting
Vein congestion and kidney injury after heart surgery
This trial looks at how fluid buildup in veins might relate to kidney injury after planned heart surgery. It aims to find ways to prevent kidney damage. Participants must be having planned (non-emergency) heart surgery, be 18 or older, and have healthy kidneys and overall health.
Yangzhou, JiangsuAges 18 years+ - NCT06802224RecruitingPhase 4
Medication to prevent kidney injury after major surgery
This study compares two medications given during surgery to see which one better protects the kidneys after the procedure. If you are having major non-cardiac surgery that lasts at least 2 hours and you need medication to support your blood pressure, this trial may be a good fit.
San Francisco, CaliforniaAges 18 years+ - NCT06918301Recruiting
Comparing heart measurements in cardiac surgery patients
This trial compares three ways to measure how well your heart pumps blood after cardiac surgery. It uses a standard catheter and two newer monitors to see which is most accurate.
KarlsburgAges 18 years+ - NCT07417462Recruiting
Pain relief after heart surgery to help you recover faster
This trial tests a combination of pain medicines given during cardiac surgery to reduce pain and speed up recovery. It may help patients who are having a first-time bypass surgery through a standard breastbone incision.
AsyutAges 40–60 - NCT04389463Recruiting
Study of heart surgery outcomes during COVID-19
This study looks at how people do after heart or chest surgery when they test positive for COVID-19. It may help doctors understand risks and outcomes for surgical patients during the pandemic.
NantesAges 18 years+ - NCT07640646Recruiting
Heart Surgery and Long-Term Pain: A Patient Survey

Leuven, Vlaams BrabantAges 18 years+ - NCT07059715Recruiting
Studying blood flow during heart surgery for vasoplegia risk
This study looks at blood flow in small and large vessels during heart surgery to understand and predict vasoplegic syndrome, a dangerous drop in blood pressure. It may help find patients at risk and improve their care.
ParisAges 18 years+ - NCT06613178RecruitingPhase 4
IV acetaminophen for heart surgery recovery
This trial tests if giving acetaminophen (Tylenol) through a vein after heart surgery can help patients recover better. You may be a good fit if you are having planned heart surgery that is not an emergency.

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.
