Breathing training for heart surgery recovery with neck posture problems
This trial tests whether a breathing exercise device can improve heart and lung function in men who had heart bypass surgery at least 3 months ago and also have neck pain from poor posture. It may help you breathe better and feel stronger after surgery.
Giza, Giza GovernorateAges 45–55 - NCT06885268RecruitingPhase 3

This trial tests whether noradrenaline is better than standard care for preventing dangerously low blood pressure during surgery. If you are having non-cardiac surgery that lasts at least an hour and are expected to stay overnight, this study may be for you.
KatowiceAges 45 years+ - NCT06355063Recruiting
CellFX device for atrial fibrillation during open-heart surgery
This trial tests a new device called CellFX that uses nanosecond pulsed field ablation to treat atrial fibrillation during open-heart surgery. It may help you if you already need heart surgery and also have AFib.
ViennaAges 18–85 - NCT07168421RecruitingPhase 4
Landiolol to prevent fast heart rate during major surgery
This trial tests a short-acting medicine called landiolol to see if it can prevent dangerously fast heart rates during and after major surgery. It is for people who have heart risks and are having a planned non-cardiac surgery.
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+ - 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+ - NCT07385092Recruiting
Continuous monitoring after non-cardiac surgery
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+ - 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 - 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+ - 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+ - 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+ - 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+ - 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+ - 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+ - NCT07405333Recruiting
Coughing exercises vs breathing device after heart surgery in children

- Are there clinical trials for cardiac surgery?
- Yes. Clin2 currently lists 311 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.
