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.
RennesAges 18 years+ - NCT06918301Recruiting
Comparing heart measurements in cardiac surgery patients
This trial compares three ways to measure how well your heart pumps blood after cardiac surgery. It uses a standard catheter and two newer monitors to see which is most accurate.
KarlsburgAges 18 years+ - NCT04754022Recruiting
Blood use during heart surgery in younger adults
This study looks at how much donated blood (blood products) is needed for younger adults during heart surgery that uses a heart-lung machine. It may help doctors choose safer, more appropriate blood-saving plans for people like you.
Portland, MaineAges 18–65 - NCT06437886Enrolling by invitation
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 - NCT07077824Recruiting
Nerve block to reduce artery catheter complications in heart surgery
This trial tests whether a nerve block (stellate ganglion block) can reduce complications from placing an artery catheter during heart surgery. It is for people with weak heart function (EF below 35%) or severe lung hypertension who are expected to have a long surgery.
CairoAges 18 years+ - 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+ - NCT07081009Recruiting
Heart injury after planned back surgery study
This study is looking at whether patients having planned lower back surgery experience any heart stress afterward. It aims to understand how common this is and what might help protect the heart.
AnkaraAges 18 years+ - NCT07059715Recruiting
Studying blood flow during heart surgery for vasoplegia risk
This study looks at blood flow in small and large vessels during heart surgery to understand and predict vasoplegic syndrome, a dangerous drop in blood pressure. It may help find patients at risk and improve their care.
ParisAges 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+ - NCT06632613RecruitingPhase 2
Trial of ENN0403 to prevent kidney injury after heart surgery
This study tests a new drug (ENN0403) given during heart surgery to see if it prevents acute kidney injury—a sudden drop in kidney function. The trial is for people who are already at higher risk due to their specific heart surgery and other health factors.
ShanghaiAges 18–85 - 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+ - NCT06970925RecruitingEarly Phase 1
Iron supplement after heart surgery study
This trial tests whether a special iron supplement (Sucrosomial® Iron) helps patients recover from heart surgery better than standard care. It is for people who have low iron or anemia after their planned heart surgery.
Englewood, New JerseyAges 18 years+ - NCT07513974Recruiting
Pain sensitivity test to predict opioid needs in heart surgery
This study measures how sensitive you are to pain using a special device, then tracks how much pain medication you need during heart surgery. The goal is to see if pain sensitivity can predict opioid requirements and help doctors customize pain control for you.
Brussels, AnderlechtAges Any age - 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+ - NCT06554925Recruiting
Sex differences in cardiac surgery patients
This study looks at how men and women may differ in their experiences and outcomes after heart surgery. It may help doctors provide better care for all patients.
Amsterdam, North HollandAges 18 years+ - NCT07037043RecruitingPhase 3
Steroid medicines for high-risk heart surgery patients
This trial tests whether adding two common medicines, hydrocortisone and fludrocortisone, to standard care can help people who are at higher risk during planned heart surgery. It aims to see if this combination can reduce serious complications after surgery.
AmiensAges 18 years+ - NCT07518524Recruiting
Fast Recovery After Heart Valve Surgery
This trial compares two recovery approaches after heart valve surgery: one that wakes you up very quickly in the operating room, and one that's slightly less aggressive. Both use techniques that avoid large chest incisions. The goal is to see which approach gets you breathing on your own sooner and helps you recover faster.
Legnano, ItalyAges 18 years+ - NCT06673953Recruiting
Breathing training for heart surgery recovery with neck posture problems
This trial tests whether a breathing exercise device can improve heart and lung function in men who had heart bypass surgery at least 3 months ago and also have neck pain from poor posture. It may help you breathe better and feel stronger after surgery.
Giza, Giza GovernorateAges 45–55 - NCT06984276Recruiting
Nerve blocks for pain relief in children having heart surgery
This study compares two different ultrasound-guided numbing injections (pectoral nerve block vs. transverse thoracic plane block) to see which provides better pain control for children aged 6 months to 7 years undergoing heart surgery through a chest incision with a heart-lung machine.
CairoAges 6 months–7 years - NCT06175650Recruiting
Female-focused recovery plan after heart surgery
This study looks at how to improve recovery after heart surgery, especially for women. It reviews medical records from people who had heart surgery in the past or will have it in the next few years at two hospitals in Amsterdam.
Amsterdam, North HollandAges 18 years+ - NCT06136637Recruiting
Monitoring glycocalyx to predict complications after heart surgery
This study will see if measuring a substance in your blood (glycocalyx) can help doctors predict problems after heart surgery that uses a heart-lung machine. The goal is to improve care after surgery.
RouenAges 18–80 - 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+ - NCT07484477Recruiting
Sitting less to improve heart and lung function after heart surgery
This study tests whether helping people sit less and move more after heart surgery can improve their breathing, heart function, and quality of life. If you're between 50 and 80 and have had heart surgery, this may help you recover better.
