Recruiting studies
- NCT07611890RecruitingPhase 4
Comparing two medications to reduce heart stress during cardiac surgery

Numbing injection study for kids’ scoliosis back surgery pain
This trial tests whether a specific numbing injection (placed in the muscles of the back) can improve pain control for children having one-stage scoliosis surgery. It may help reduce post-surgery pain needs and improve comfort.
Palo Alto, CaliforniaAges Up to 18 years - NCT04750616RecruitingPhase 2
NAD+ for heart injury prevention around non-emergency surgery
This Phase 2 trial studies whether adding NAD+ can reduce heart muscle injury around scheduled heart surgery. It may help protect the heart (and possibly kidneys) in people considered higher risk for complications.
San Francisco, CaliforniaAges 18 years+ - NCT04833751Recruiting
Study of heart and brain monitoring around heart surgery anesthesia
This study collects heart and brain signal information before and during anesthesia for people having cardiovascular surgery or procedures. The goal is to better understand risk and outcomes, and to improve how anesthesia is assessed.
SeoulAges 19 years+ - 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 - NCT05573633Recruiting
Smartwatch test to detect irregular heartbeats after heart surgery
This study checks whether a smartwatch can spot an irregular heartbeat called atrial fibrillation soon after on-pump heart surgery. If the smartwatch works well, it could help clinicians find the problem earlier after surgery.
AmiensAges 18 years+ - NCT05635227Recruiting
Medications during heart surgery to help control breathing and circulation
This study looks at whether giving dexamethasone and olanzapine during certain heart surgeries can improve how blood flow and ventilation (breathing support) are managed. It’s meant to see if these medicines help the body handle heart-lung bypass more safely.
CopenhagenAges 18 years+ - NCT05849597RecruitingPhase 3
Dexmedetomidine to prevent delirium after open-heart surgery
This trial tests whether a sedating medicine called dexmedetomidine can reduce the risk of “delirium” (sudden confusion) in the intensive care unit after open-heart surgery. If you’re having certain heart operations, it may help protect your thinking and alertness during recovery.
KamenitzAges 18 years+ - NCT06012760Recruiting
Can iron and vitamin C reduce transfusions during heart surgery?
This trial is testing whether giving iron plus vitamin C before heart surgery can reduce the need for blood transfusions. It is for people with low iron and anemia who are scheduled for bypass or valve surgery.
Hangzhou, ZhejiangAges 18 years+ - NCT06133842Recruiting
Brain blood flow and confusion after surgery study
This trial looks at how well the brain controls its own blood flow during non-cardiac surgeries. It aims to see if problems with this regulation are linked to confusion after surgery (delirium).
Boston, MassachusettsAges 60 years+ - NCT06291714Recruiting
Non-invasive blood pressure prediction during major surgery
This trial tests a new, non-invasive way to predict drops in blood pressure during major hip, knee, pelvis, or spine surgery. The goal is to help doctors prevent low blood pressure, which can lead to complications.
GiessenAges 45 years+ - NCT06322810Recruiting
Pain relief methods for open heart surgery: ESP vs PIFB
This study compares two ways to manage pain after open-heart surgery. It looks at using an injection near the spine (ESP block) versus a needle placed through the chest wall (PIFB) to help reduce pain and the need for strong pain medicines.
Taichung, TaiwanAges 18 years+ - NCT06361238RecruitingPhase 3
Liraglutide to prevent confusion after heart surgery in seniors with diabetes
This trial is testing if liraglutide, a diabetes medication, can prevent delirium (sudden confusion) in older adults with type 2 diabetes who are having planned heart surgery. If you qualify, you may help find a new way to protect brain function after surgery.
Nanjing, JiangsuAges 60 years+ - NCT05999721Recruiting
Nerve block for better breathing after heart surgery
This trial is testing a nerve block (a numbing injection) placed near the breastbone to see if it helps your lungs work better after heart surgery. If you are having planned heart surgery through a breastbone cut, you may be able to join.
Petah TikvaAges 18 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.
Kochi, KeralaAges 18–80 - NCT06554119Recruiting
Surgery for tricuspid valve leaks after prior heart surgery
This study looks at different surgeries for a leaky tricuspid valve that happened after earlier heart surgery. It may help doctors learn which approach works best for patients like you.
Guangzhou, GuangdongAges 16 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 - 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+ - 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 - NCT06790277Recruiting
Foam cushion study for heart surgery patients
