Recruiting studies
- NCT06702553RecruitingPhase 3

Finding the best temperature during heart-lung machine surgery
This study looks at the best body temperature to use during heart surgery when a heart-lung machine is needed. You may be able to join if you are having bypass surgery or valve repair, your risk score is moderate or higher, and your surgery is not an emergency.
Leicester, LeicestershireAges 18 years+ - NCT07292532Recruiting
Teaching CPR in Schools: the RCP-KNOW Project
This study tests a new way to teach schoolchildren how to perform CPR (a life-saving technique for when someone stops breathing or their heart stops). It aims to find the best approach to teach these skills in schools.
Cuenca, CuencaAges 5–13 - NCT07094087RecruitingPhase 3
Blood clotting medicine for heart surgery bleeding
This trial tests a medicine called 4F-PCC to stop bleeding during complex heart surgery that uses a heart-lung machine. It could help people who have bleeding problems after the surgery.
Los Angeles, CaliforniaAges 18 years+ - NCT05924555Recruiting
Exercise testing in inherited fatty acid breakdown disorders

Amsterdam, North HollandAges 18 years+ - NCT06702059Recruiting
Heart exercise test for bypass surgery patients
This trial uses a special exercise test to measure heart and lung function in people scheduled for coronary artery bypass surgery. It may help doctors understand how well patients recover after surgery.
Brno, Czech RepublicAges 18 years+ - NCT07683299Recruiting
New heart monitoring during bypass surgery
This study tests a new way to monitor your heart and blood flow during heart surgery that uses a heart-lung machine. The goal is to see if this integrated approach helps doctors make better decisions during the operation.
Medellín, AntioquiaAges 18 years+ - NCT05678530Recruiting
Study uses routine exercise test to check fitness measuring methods
This observational study does not change your treatment. It collects results from your usual cardiopulmonary exercise test (CPET) to help validate better ways to estimate VO2max, a measure of exercise capacity.
Scottsdale, ArizonaAges 18 years+ - NCT07519733Recruiting
Exercise Testing Before High-Risk Surgery
This study tests whether a simple exercise test before surgery can help doctors better predict and prevent complications in older adults undergoing major operations. You'll do a gentle exercise test on a stationary bike or treadmill to measure your fitness level.
New Haven, ConnecticutAges 45 years+ - NCT07249671Recruiting
Rope skipping for kids' heart and lung fitness
This study tests if rope skipping can improve heart and lung fitness in healthy children ages 6 to 12. It may help kids get more active and build endurance.
Chak Four Hundred Fifty-four, Punjab ProvinceAges 6–12 - NCT07354841Recruiting
Testing safety of heart-lung machine tubes
This study tests two types of tubes used during heart surgery to connect you to a heart-lung machine. It aims to see if they work safely and effectively.
Bari, BAAges 18 years+ - NCT07016022Recruiting
Heart and lung test before chest surgery helps predict risks
This study checks if a simple test of your heart and breathing before chest surgery can help predict problems after the operation. It looks at people having surgery for lung, esophagus, stomach, or chest tumors.
Ottawa, OntarioAges 18 years+ - NCT07005193Recruiting
Cleaner cooking and ventilation for better heart and lung health
This study tests if switching to cleaner LPG gas stoves and adding kitchen fans can reduce indoor air pollution and improve your heart and lung health. You would be asked to use a new stove and fan, and we will check your health over time.
Zhumadian, HenanAges 18–75 - NCT06972784Recruiting
Heart and lung health study at Xiangya Hospital
This study looks at how heart and lung function are related over time. You may be able to join if you have had both a heart test (like an echo) and a lung test (like a breathing test) within one year of each other, and if your medical records are complete.
Changsha, HunanAges Any age - NCT05740397Recruiting
Testing blood pressure targets during heart-lung bypass
This trial compares different strategies for keeping a specific blood pressure level during heart-lung bypass surgery. It may help reduce complications by finding the safest blood pressure target during the operation.
VeronaAges 18–80 - 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 - NCT06792617Enrolling by invitationEarly Phase 1
Exercise for people on ECMO life support
This study tests if gentle exercise in bed can help people on ECMO (a life-support machine for heart and lungs) get stronger and recover faster. It is for adults in the ICU who are stable enough to move safely.
San Antonio, TexasAges 18 years+ - NCT07508579Recruiting
Hypothermia's effect on brain monitoring during heart surgery
This study tests if lowering body temperature during heart surgery affects how two brain-monitoring devices track anesthesia depth. It may help doctors better manage anesthesia during bypass surgery.
Sakarya, SerdivanAges 18–80 - NCT04296071Recruiting
Testing blood markers after heart surgery in infants
This trial studies patterns in immune cells (neutrophils) in very young children who undergo heart surgery using a heart-lung machine. The goal is to better understand and potentially reduce lung injury after surgery.
Boston, MassachusettsAges Up to 1 year - NCT05189262Recruiting
Study of blood changes during heart surgery bypass
This study looks at whether a machine used during heart surgery (cardiopulmonary bypass) causes red blood cells to break down. The goal is to better understand these blood changes and what they might mean for patients during and after surgery.
Baltimore, MarylandAges 18–88 - NCT05487612Recruiting
MiECC heart-lung machine vs standard bypass during heart surgery
This trial compares a newer heart-lung machine setup (MiECC) with the usual bypass technique during certain heart operations. It may help see whether MiECC changes outcomes like the need for blood transfusions or recovery after surgery.
TorontoAges 18–85 - NCT06013189Recruiting
Adjusting gas flow during heart-lung machine rewarming
This study tests how adjusting the amount of sweep gas (a gas mixture) during the rewarming phase of heart-lung machine use might affect patients. It's for people having planned heart surgery with a standard heart-lung machine, not minimally invasive or robotic surgery.

Exercise testing for girls with Turner syndrome
This study will have girls with Turner syndrome do a cardiopulmonary exercise test (a special bike or treadmill test) to check how their heart and lungs work during exercise. It may help doctors better understand fitness and health in Turner syndrome.

Common questions
- Are there clinical trials for cardiopulmonary?
- Yes. Clin2 currently lists 165 recruiting cardiopulmonary 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 cardiopulmonary 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 cardiopulmonary 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.
