Brain monitoring and frailty to predict confusion after surgery in older adults
This study tests if monitoring your brain waves during surgery and checking your frailty level can help predict whether you might become confused after surgery. It aims to improve care for older adults having major non-cardiac operations.
Saint-EtienneAges 75 years+ - NCT06527105Recruiting
Sleep quality and recovery after heart surgery
This study looks at how your sleep affects recovery after planned heart surgery. Researchers want to see if better sleep leads to better outcomes, so they will track your sleep quality and health after the operation.

This trial tests if a medication called dexmedetomidine can help prevent postoperative delirium (sudden confusion and disorientation) after heart surgery. It is for adults having heart surgery with a heart-lung machine.
Xi'an, ShaanxiAges 18 years+ - NCT06706258RecruitingPhase 2
Preventing kidney injury after heart surgery with a stomach acid drug
This trial tests whether giving a common stomach acid medication (a proton pump inhibitor) before, during, and after heart surgery can help prevent acute kidney injury. If you are at moderate to high risk for kidney problems after surgery, this study may be a good fit.
Houston, TexasAges 18–90 - NCT06706323Recruiting
Depression after heart surgery study
This study looks at depressive symptoms in people who have had heart bypass surgery. It aims to understand how patients feel emotionally after surgery and may help improve care.
ZurichAges 18–90 - NCT06225453Recruiting
Personalized blood pressure care during surgery
This study compares a personalized approach to managing blood pressure during surgery with the usual one-size-fits-all method. It looks at older adults or those with certain heart or blood vessel conditions having non-emergency surgery to see if individual targets can improve recovery.
SeongnamAges 45 years+ - NCT06722196RecruitingPhase 3
Amiodarone patch to prevent afib after heart surgery
This trial tests a biodegradable patch that slowly releases amiodarone directly onto the heart during surgery. It aims to prevent atrial fibrillation, a common irregular heartbeat after heart surgery.
Changchun, JinlinAges Any age - NCT06728371RecruitingPhase 3
IV methadone for pain after heart surgery
This trial tests if methadone given through a vein can control pain better after heart surgery done through a breastbone incision. It may be an option for adults having planned heart surgery who are expected to wake up and breathe on their own within 12 hours.
Hong KongAges 18 years+ - NCT06730828RecruitingPhase 1/Phase 2
Amiodarone patch to prevent new irregular heartbeat after heart surgery
This trial tests a patch that releases amiodarone, a medicine that helps prevent a common irregular heartbeat after open-heart surgery. The patch is placed on the heart during surgery to stop new atrial fibrillation from starting.
Louisville, KentuckyAges 20–85 - NCT06775639Recruiting
Can we skip a heart artery test before surgery?
This study looks at whether people with adult congenital heart disease can skip a pre-surgery artery test (coronary angiography) if they already had a CT scan. If you qualify, you might help doctors find safer, simpler ways to prepare for heart surgery.
BolognaAges 18 years+ - NCT06778811RecruitingPhase 4
Sleep quality study for heart surgery patients
This trial studies sleep problems before and after heart surgery. It tests two medicines to see if they can help improve sleep. This may help you recover better after surgery.
Nanjing, JiangsuAges 40–75 - NCT06788743Recruiting
Sevoflurane vs. propofol for preventing confusion after surgery in older diabetics
This trial compares two common anesthesia drugs (sevoflurane gas vs. propofol injection) to see which one lowers the risk of confusion or delirium after surgery in older adults with diabetes. It aims to find a safer way to give anesthesia for your operation.
Xi’an, ShanxiAges 60 years+ - NCT06790277Recruiting

Mecca, Western ReaganAges 18 years+ - NCT06798714RecruitingPhase 4
Colchicine to prevent irregular heartbeat after heart surgery
This trial tests whether the drug colchicine can reduce the chance of developing atrial fibrillation (an irregular heart rhythm) after open-heart surgery. If it works, it could help you recover more smoothly.

- 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.
