Bordeaux, FranceAges 75 years+ - NCT05664308Recruiting
Watch-based heart rhythm monitoring after heart surgery
This study tests whether a connected watch can help monitor an irregular heart rhythm (atrial fibrillation) after heart surgery. It looks at people who develop new atrial fibrillation after surgery and compares how well monitoring works over the next 12 months.
Nantes, Loire AtlantiqueAges 18 years+ - NCT05166954Recruiting
Bariatric surgery and heart function in people with high blood pressure
This study looks at whether bariatric (weight-loss) surgery improves heart function in people who have high blood pressure. You may be able to join if you’re already a bariatric surgery patient at the study hospital and meet the health and medication criteria.
Beijing, Beijing MunicipalityAges 17–70 - NCT06620523RecruitingPhase 2
Preventing kidney injury after heart bypass surgery
This trial tests whether combining two natural supplements (CoQ10 and glutathione) can protect your kidneys during heart bypass surgery. It may help prevent acute kidney injury, a common complication after these procedures.
Washington D.C., District of ColumbiaAges 18–70 - NCT06800781Recruiting
Chest tube duration to prevent afib after heart surgery
This trial tests if leaving a chest tube in a little longer after heart surgery can lower the chance of developing atrial fibrillation (an irregular heart rhythm). It's for people having certain planned heart surgeries who have not had this rhythm problem before.
LundAges 18 years+ - NCT06001502Recruiting
Virtual reality for pain and anxiety after heart bypass surgery
This trial tests whether using virtual reality (VR) goggles after heart bypass surgery can help reduce pain and anxiety. If you are having a planned CABG and have no major vision, hearing, or other health issues, you may be eligible.
Amsterdam, North HollandAges 18 years+ - NCT07193719RecruitingPhase 1/Phase 2

Cairo, Cairo GovernorateAges 45–60 - NCT05595954Recruiting
Personalized anesthesia plan to protect the brain during heart surgery
This trial studies whether tailoring anesthesia and monitoring the brain’s blood-flow control during heart surgery can improve neurological outcomes (brain-related function and recovery). It may help by guiding anesthesia in a more individualized way and checking how well the brain is protected during the operation.

Common questions
- Are there clinical trials for cardiac surgery?
- Yes. Clin2 currently lists 310 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.
