Nerve block for pain after open-heart surgery
This study tests a nerve block (an injection near the back muscles) to see if it helps control pain after open-heart surgery. It might be a good option if you are having planned heart surgery through a cut in the middle of your chest.
SamsunAges 18–80 - NCT07391683Recruiting

Innsbruck, TyrolAges 18 years+ - NCT04880265Recruiting
Study heart rhythm changes after open-heart surgery
This study looks at how often and how long an irregular heartbeat (atrial fibrillation) happens after planned open-heart surgery. It aims to better understand the “burden” of this rhythm problem, which could help improve care for future patients.
Boston, MassachusettsAges 20–90 - NCT07418242Recruiting
New markers for kidney risk after heart surgery
This study looks at whether certain blood or urine markers can predict kidney problems in people having high-risk heart surgery. The goal is to find early warning signs so doctors can take steps to protect your kidneys.
Shanghai, Shanghai MunicipalityAges 18–90 - 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 - NCT07472959RecruitingPhase 4
Morphine for pain after heart bypass surgery
This study tests whether giving morphine during coronary artery bypass surgery can help control pain after the operation. It is for people having planned heart bypass surgery who are moderately sick and not already on strong pain medicines.
Istanbul, Outside of the USAges 18–80 - NCT07532174Recruiting
Blood-Cleaning Device During Heart Surgery
This trial tests a special blood-filtering device (Efferon LPS) used during heart surgery to reduce inflammation and improve recovery. The device removes harmful substances from your blood during the operation.
BarnaulAges 18 years+ - NCT07539623RecruitingPhase 3
Pain relief with suzetrigine after heart or weight-loss surgery
This study tests whether suzetrigine, a new pain medication, can reduce the need for opioids (strong painkillers) after cardiac or bariatric surgery. The goal is to help patients manage pain with fewer opioid-related side effects.
New York, New YorkAges 18–85 - NCT07549243Enrolling by invitation
Ear Nerve Stimulation to Protect Kidneys During Heart Surgery
This trial tests whether gentle electrical stimulation applied to your ear can help protect your kidneys during heart surgery that uses a heart-lung machine. Kidney damage after this type of surgery is common, and researchers want to see if this non-invasive stimulation can prevent it.
Hangzhou, ZhejiangAges 18 years+ - NCT06516432Recruiting
Nerve block and lactate in heart surgery
This study looks at how a nerve block near the breastbone (parasternal block) affects lactate levels in the blood for patients having heart surgery. It aims to understand if this pain management technique can help keep lactate levels normal during recovery.
Guadalajara, JaliscoAges 18 years+ - NCT06786819Recruiting
Recovery app after heart bypass surgery
This study tests whether a smartphone app that helps you follow a recovery plan can shorten the time you need to stay in the hospital after coronary artery bypass (heart bypass) surgery. If you are scheduled for this surgery, have a smartphone, and are comfortable using it, this app might help you get home sooner.
São Paulo, São PauloAges 18 years+ - NCT07032792RecruitingPhase 2
FEIBA versus plasma for bleeding after heart surgery
This trial compares two treatments for bleeding after heart surgery: a medicine called FEIBA (which helps blood clot) and fresh frozen plasma (a blood product). The goal is to see which works better as a first treatment for bleeding during recovery.
Manhasset, New YorkAges 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+ - NCT06059976Recruiting
Hypnosis during heart surgery recovery study
This study looks at the use of hypnosis during heart surgery to see how it affects recovery. If you are having major heart surgery and have already had hypnosis sessions before, during, or after the operation, you may be eligible to participate.
GrenobleAges 18 years+ - NCT06001489Recruiting
Virtual reality for anxiety before heart surgery
This trial tests whether watching a 360-degree virtual reality video can help reduce anxiety before heart surgery. If you are waiting for elective heart surgery and are at least 18 years old, you may be able to participate.
Amsterdam, North HollandAges 18 years+ - NCT06747806Recruiting
A heart surgery biobank study
This study collects tissue samples from children and adults having heart surgery. The samples will help researchers learn more about heart conditions and improve future treatments.
Hyde Park, IllinoisAges Any age - 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 - NCT04284839RecruitingPhase 3
Blood thinner pills vs warfarin after heart surgery
This trial compares two ways to prevent blood clots after open heart surgery: a “direct oral” blood thinner pill versus warfarin (a vitamin K antagonist). It may help find the safest and most effective option for people who develop atrial fibrillation after surgery.
Fitzroy, VictoriaAges 18 years+ - NCT06817005Recruiting
Pain monitoring during heart surgery
This trial tests a device to measure pain during heart surgery using a heart-lung machine. It may help doctors better manage your pain during the procedure.
StrasbourgAges 18 years+ - NCT06396767Recruiting
Breathing test before heart surgery to predict lung problems
This study uses a simple breathing test before scheduled heart surgery to see if it can help predict breathing or lung complications after the operation. The results may help doctors identify patients who need extra support during recovery.
London, OntarioAges 19–99 - NCT05833828Recruiting
Testing blood-pressure hormone changes during bypass surgery
This study looks at how a blood-pressure hormone system (RAAS) changes during coronary artery bypass surgery. It may help researchers understand better how to manage blood pressure and heart stress around the time of surgery.

- Yes. Clin2 currently lists 386 recruiting cardiac surgery patients 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 patients 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 patients 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.
