Recruiting studies
- NCT06794697Recruiting
Does admission day affect anxiety before heart surgery?
This study looks at whether the day you are admitted to the hospital for planned heart surgery affects your anxiety levels before the operation. The goal is to help hospitals schedule admissions in a way that lowers stress for patients.

Comparing high-dose vs. lower-dose opioid anesthesia for heart surgery
This trial compares two types of anesthesia during heart surgery: one that uses high doses of strong painkillers (opioids) and one that uses less opioids. The goal is to see which approach is safer and helps patients recover better.
BeijingAges 45–70 - NCT06702553RecruitingPhase 3
Nitric oxide to reduce support after heart surgery
This trial tests whether giving nitric oxide gas during heart surgery can help patients recover faster and need less breathing and circulation support afterward. It is for people having planned heart or aortic surgery with a heart-lung machine for the first time.
Boston, MassachusettsAges 18 years+ - NCT06986187Recruiting
Predicting difficult airways in heart surgery patients
This study measures how often difficult airways occur during heart or blood vessel surgery and builds a way to predict them beforehand. It may help your care team prepare for safer airway management during your procedure.
AnkaraAges 18 years+ - NCT06287619RecruitingPhase 2
IV iron after heart surgery for iron deficiency
This trial tests whether giving iron through a vein after heart surgery can help fix low iron levels and improve recovery. It is for people who have iron deficiency (with or without anemia) before their planned heart surgery.
Kingston, OntarioAges 18 years+ - NCT07541222Recruiting
Blood pressure medications and surgery recovery outcomes
This study looks at how blood pressure medications affect low blood pressure episodes that happen during and after heart surgery. Researchers want to understand if the number of blood pressure drugs you take before surgery changes how your body handles blood pressure during the operation.
KonyaAges 40 years+ - NCT07200726Recruiting
Brain inflammation and thinking after heart surgery
This study looks at whether brain inflammation during heart surgery may affect memory and thinking. It includes people aged 60 and older who are having planned heart surgery.
Genk, LimburgAges 60 years+ - NCT07024420Recruiting
Sigh breathing during heart surgery with heart-lung machine
This study tests if adding occasional deep breaths (sighs) during heart surgery helps patients recover better after using the heart-lung machine. It is for people having planned (not emergency) heart surgery.
Nanjing, JiangsuAges 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 - NCT04389463Recruiting
Study of heart surgery outcomes during COVID-19
This study looks at how people do after heart or chest surgery when they test positive for COVID-19. It may help doctors understand risks and outcomes for surgical patients during the pandemic.
NantesAges 18 years+ - NCT05817929Recruiting
Angiopoietin levels and outcomes after heart bypass surgery
This study looks at how a blood protein called angiopoietin relates to recovery and complications after heart surgery that uses a heart-lung machine. If you’re having scheduled heart bypass-type surgery, your team may take blood samples to see whether these levels can help predict outcomes.
AmiensAges 18 years+ - NCT06137547Recruiting
Preventing low blood pressure during heart surgery with HPI
This trial tests a new method (called HPI) to prevent dangerously low blood pressure during planned heart surgery. It is for adults having bypass surgery or valve surgery, but not for those with certain heart rhythm problems or needing emergency surgery.
TaipeiAges 18 years+ - NCT06371976Recruiting
Stress hormone system study after heart surgery
This study looks at how your body's stress hormone system (the HPA axis) works after heart surgery if you develop vasoplegic syndrome (a serious drop in blood pressure). The goal is to understand if giving extra steroids might help. If you are scheduled for heart surgery with a heart-lung machine, you may be able to join.
Paris, Île-de-France RegionAges 18 years+ - NCT06279793RecruitingPhase 2
Fish oil for recovery after high-risk heart surgery
This trial tests if giving fish oil through a vein before and after heart surgery can help patients recover faster. It is for people who have a high risk of complications during surgery.
AugsburgAges 18 years+ - NCT06637137Recruiting
Blood management for cardiac surgery patients
This trial studies a program to manage blood levels before, during, and after heart surgery. It may help reduce the need for blood transfusions and improve recovery.
RomaAges 18 years+ - NCT06705855Recruiting
Predicting kidney injury after heart surgery using skin sensors
This study tests whether a special light-based monitor on your skin (near your kidney and arm) can predict kidney injury after heart surgery. It aims to help doctors protect your kidneys during and after the procedure.
Salt Lake City, UtahAges 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+ - NCT06786416Recruiting
Monitoring to prevent kidney injury after heart surgery
This trial is testing a new monitoring system that tracks blood flow and other vital signs during heart surgery to help prevent kidney damage afterward.
San Donato Milanese, MilanoAges 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+ - NCT06978179Recruiting
Nerve blocks for pain after lower belly surgery
This trial compares two types of nerve blocks (QL block vs TAP block) to see which one provides better pain relief after lower abdominal surgery. If you are having this surgery, you may be able to join and receive one of these blocks to help manage your pain.
SohagAges 18–65 - NCT07077772Recruiting
Guiding fluid removal after heart surgery
This trial tests a method to guide how much fluid is removed after heart surgery using a urine salt test, to see if it helps patients recover better. If you are having planned heart surgery with a heart-lung machine, you may be able to join.
AmiensAges 18 years+ - 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 - 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.
