BaselAges 60 years+ - NCT03209674Recruiting
Registry tracking outcomes after heart and chest surgery
This is a registry that collects information from people who have heart or chest (thoracic) surgery. It may help doctors understand what improves outcomes after surgery, but it usually does not test a new drug.
Neuilly-sur-Seine, Île-de-France RegionAges Any age - NCT04973579Recruiting
Stent plus heart surgery for high risk carotid patients
This trial looks at whether doing carotid artery stenting at the same time as heart surgery is safe and effective for people at high risk of stroke around the time of surgery. It targets people with significant carotid narrowing who also need heart surgery for specific heart problems.
KrakowAges 18 years+ - NCT06144125RecruitingPhase 4
Blood management trial for heart surgery patients
This trial compares two treatments (prothrombin complex concentrate and fresh frozen plasma) for managing bleeding during heart surgery. It aims to find which approach works better and is safer for patients.
Seoul, SeoulAges 20–75 - NCT05833048Recruiting
Pain-relief nerve block during cardiac surgery
This study tests whether a numbing “nerve block” placed in the rectus sheath area can reduce pain for people having certain heart surgeries with chest tubes. If you qualify, it may help your comfort during recovery, but it also depends on how suitable you are for local anesthesia.
New York, New YorkAges 18–85 - NCT05786274Recruiting
Predicting stroke risk after heart surgery using heart signals and MRI
This study looks at ways to predict harmful brain and blood-vessel side effects after heart surgery. It may help doctors identify higher-risk patients sooner so they can monitor them more closely.
San Donato Milanese, MilanAges 18 years+ - NCT06772025Recruiting
Understanding kidney injury after heart surgery with heart-lung machine
This study looks at why some people develop kidney damage after heart surgery that uses a heart-lung machine. It aims to help doctors better predict and prevent this complication.
Bad Oeynhausen, North Rhine-WestphaliaAges 18 years+ - NCT07164833RecruitingPhase 2
Testing a drug to prevent kidney injury after heart surgery
This study tests a new medicine, BX-001N, to see if it can prevent kidney damage during and after heart surgery for aortic disease. It is for people with moderate kidney problems who are having planned surgery that stops the heart briefly.
DaeguAges 19–90 - 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+ - NCT06952907Recruiting
Arm vs. leg artery pressure monitoring in heart surgery
This study compares measuring blood pressure through an arm artery (radial) versus a leg artery (femoral) during heart surgery that uses a heart-lung machine. The goal is to see which method works better and is safer for patients.
BesançonAges 18 years+ - NCT06493227Recruiting
Extended use of bleeding control drugs after heart surgery
This trial is for hospitals, not patients. Hospitals that do many open heart surgeries and whose doctors agree to use certain bleeding control drugs (fibrinolysis inhibitors) as per the study protocol can participate.
Saint PetersburgAges 18 years+ - NCT04331249Recruiting
Monitoring heart device during and around your procedure
This trial looks at how to manage and check implanted heart devices (pacemakers/defibrillators) during and around a planned procedure. It may help teams improve safety and decision-making during surgery or catheter procedures.
Fürth, BavariaAges 18 years+ - NCT05197972Recruiting
Hypnosis and heart-breathing training to reduce cancer surgery anxiety
This study tests whether guided “heart-breathing” and hypnosis (through an app) can lower anxiety before cancer surgery. It may help you feel calmer in the days leading up to the operation.
Montpellier, HéraultAges 18 years+ - NCT07622823Recruiting
Nerve Blocks to Reduce Pain After Heart Surgery
This study tests whether special numbing injections around nerves (called fascial plane blocks) can help reduce pain and improve recovery after planned heart surgery. The goal is to see if this technique helps patients manage pain better and recover faster.
AntalyaAges 18 years+ - NCT07531602Enrolling by invitation
How breathing pressure affects heart function during surgery
This study observes how different levels of breathing support during heart surgery affect your heart's function. Researchers will use ultrasound and monitoring tools already planned for your surgery to see how small changes in breathing pressure impact your heart's performance.
Boston, MassachusettsAges 18 years+ - NCT07496424Recruiting
Comparing manual vs automatic strain in heart surgery patients
This trial compares two ways of measuring heart strain (the heart's ability to squeeze) after cardiac surgery. It uses GE ultrasound machines and special software to see if automatic measurements are as good as manual ones.
ViennaAges 18–99 - NCT07116733RecruitingPhase 3
Comparing two anesthetics for heart bypass surgery
This trial compares two types of anesthesia (desflurane gas vs. propofol IV) during coronary artery bypass surgery to see which one is better for your heart. It might help patients who are having planned bypass surgery.
Fuzhou, FujianAges 18 years+ - NCT06205875Recruiting
High vs. low dose pain block after minimally invasive heart valve surgery
This trial compares two doses of a numbing medicine injected into the chest wall to control pain after heart valve surgery. If you qualify, you will receive either a higher or lower dose of the pain block to see which provides better pain relief and recovery.
