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+ - NCT07275307Recruiting
Test of a wound gel to prevent infections after heart surgery
This study tests whether a special gel applied to the chest incision during heart surgery can lower the chance of wound infections. The gel may help keep the incision site clean and help it heal better.

Managing brain oxygen after emergency life support
This trial tests a targeted approach to manage oxygen levels in the brain for patients who received ECMO (a machine that does the heart and lung work) after a cardiac arrest that did not respond to standard CPR. The goal is to improve brain recovery and outcomes.
Jinan, ShandongAges 18–75 - NCT06721819RecruitingPhase 3
Sleep and brain training before heart surgery to prevent delirium
This study tests whether a combination of sleep therapy, brain games, and light exercise before heart surgery can help prevent confusion or disorientation (delirium) after the operation. Participants will be asked to use a tablet and fitness tracker daily for about an hour before their surgery.
Boston, MassachusettsAges 60 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 - NCT06744530Recruiting
Heart radiation therapy for ventricular tachycardia II study
This study tests if targeted radiation therapy can help people with a serious heart rhythm problem called ventricular tachycardia (VT) that hasn't gotten better with other treatments. It aims to see if this approach can reduce dangerous heart rhythm episodes.
LeuvenAges 18 years+ - NCT06745778Recruiting
Study of heart device signals in patients with left bundle pacing
This study looks at the electrical signals recorded by a special type of pacing lead placed in the heart's left bundle branch. It aims to understand how these signals change over time in people who already have an ICD or CRT-D device.
Wenzhou, ZhejiangAges 18 years+ - NCT06747429Recruiting
High-fat diet for heart failure metabolism
This trial tests whether a high-fat diet can help change how your heart uses energy, potentially improving heart function in people with non-ischemic heart failure.
ParisAges 18 years+ - NCT06750536Recruiting
Safety study of a new lung support device for small children
This trial is testing a new device (MiniLung Petite Kit) for babies and young children with severe lung or heart failure. The device helps oxygenate the blood and remove carbon dioxide, giving the lungs and heart a chance to rest and heal.
Bonn, North Rhine-WestphaliaAges Up to 8 months - NCT06750939Recruiting
Comparing two sedatives for ICU breathing tube placement
This study compares two medicines (propofol and ketamine) used to help you relax and stay stable while a breathing tube is placed. The goal is to see which one is safer for your heart and blood pressure during this procedure in the ICU.
Köseköy, KocaeliAges 18 years+ - NCT06759389Recruiting
Ventor study for cardiac arrest outside the hospital
This trial is testing a new device or procedure for adults who have a cardiac arrest outside the hospital. It aims to see if it can help improve outcomes for patients like you.
Stony Brook, New YorkAges 18–75 - NCT06766006Recruiting
Heart-lung machine left ventricle unloading study
This study looks at how to best relieve pressure on the heart while a heart-lung machine is helping to pump blood. It includes anyone who needs this support.
MaastrichtAges 1 day–80 years - NCT06770062Recruiting
How the heart changes after mitral valve repair surgery
This study at Mayo Clinic uses MRI and other tests to see how the heart's main pumping chamber changes shape after robot-assisted mitral valve repair surgery for severe mitral regurgitation. It may help doctors better understand how patients recover.
Rochester, MinnesotaAges 18 years+ - NCT06771700Recruiting
S-ICD implantation study for heart patients
This study looks at implanting a type of ICD (implantable cardioverter-defibrillator) called a subcutaneous ICD, or S-ICD, which goes under the skin instead of in the heart. It is designed to help see how well this works in standard care.
Cologne, North Rhine-WestphaliaAges Any age - NCT06772493Recruiting
First test of a new ICE ultrasound tool in people
This study is testing a new type of ICE ultrasound tool during heart procedures. The goal is to see how well it works in real people.
Jonesboro, ArkansasAges 18 years+ - NCT06772922Recruiting
Pulmonary and heart rehab program testing combined exercise
This trial studies a combined lung and heart rehabilitation program for people with lung diseases (like COPD, asthma, or fibrosis) or heart conditions (like heart attack, bypass surgery, or heart failure). The goal is to see if a special exercise program can improve your health and quality of life.
Campinas, São PauloAges 18 years+ - 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

- How do I know if I qualify for a cardiac 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 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.
