Sitting less to improve heart and lung function after heart surgery

Testing how well people measure CPR depth and length
This study compares how accurately laypeople and healthcare providers estimate the depth and length of CPR chest compressions. It helps researchers understand if training or experience affects measurement accuracy.
SeoulAges 18 years+ - NCT07477977Recruiting
Finding the right dose of protamine to reverse heparin after heart bypass
This study is testing different doses of a medication called protamine, which is given after heart surgery to reverse the effects of heparin (a blood thinner). The goal is to find the safest and most effective dose for patients who have had a heart-lung bypass machine during surgery.

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+ - NCT06031623Recruiting
Using REBOA for non-traumatic cardiac arrest outside hospital
This study tests if a temporary balloon placed in the aorta, called REBOA, can improve blood flow to the heart and brain during CPR for people whose hearts stop due to a non-traumatic cause. It is for adults who have a witnessed cardiac arrest and arrive at the hospital during daytime hours.
Seongnam-si, Gyeonggi-doAges 20–80 - NCT07447908Recruiting
Understanding worsening heart failure after leaving the hospital
This study monitors heart failure patients after a hospital stay or urgent clinic visit to better understand the signs of worsening heart failure. It may help researchers find ways to predict and prevent future exacerbations.
Newmarket, OntarioAges 18 years+ - NCT07432477Recruiting
Lung opening techniques after heart surgery
This trial compares two methods of opening the lungs (recruitment maneuvers) after heart-lung bypass to see which works better. The study aims to help patients recover their lung function more quickly after cardiac surgery.
SamsunAges 18–80 - NCT07434726Recruiting
Balloon in aorta to improve CPR for in-hospital cardiac arrest
This trial tests if placing a balloon in the main artery (aorta) during CPR can improve blood flow to the heart and brain. It is for adults who have a cardiac arrest while already in the hospital and have a pulse-check showing some heart activity.
BernAges 18 years+ - NCT07431710Recruiting
AI-guided chest compressions for cardiac arrest in the ER
This trial tests whether artificial intelligence (AI) can help doctors give better chest compressions during CPR for adults whose hearts stopped outside the hospital. The goal is to improve blood flow and outcomes without using special equipment in the ambulance.
New Taipei City, BanqiaoAges 20 years+ - NCT07421882Recruiting
Cooling after cardiac arrest to improve brain recovery
This trial tests if starting body cooling before reaching the hospital can help protect the brain after a cardiac arrest. It is for adults who are unconscious after their heartbeat has been restored by emergency services.
SingaporeAges 16–80 - NCT06069115Recruiting
How radiation affects lung function in breast cancer patients
This study looks at how radiation therapy for breast cancer may affect your lungs over time. Researchers will measure lung function and see if problems develop, so they can better understand and protect patients.
Novosibirsk, Novosibirsk OblastAges 18 years+ - NCT06842108Recruiting
Blood flow and heart-lung fitness in type 2 diabetes
This study looks at how blood flow changes (hemodynamics) affect your heart and lung fitness (cardiopulmonary fitness) in people with type 2 diabetes. It may help doctors understand how diabetes affects the heart and lungs.
Karachi, SindhAges 30–50 - NCT07354568Recruiting
Mixed heart and blood vessel shock study
This study looks at people with a severe type of shock that affects both the heart and blood vessels, treated in the intensive care unit. It aims to understand how these patients recover and what factors impact their survival.
Amiens, SommeAges 18 years+ - NCT07326449Enrolling by invitation
CO2 measurement test on exercise bike
This trial checks if a portable device can reliably measure carbon dioxide in your breath while you rest and cycle slowly. It may help understand how your lungs work during light exercise.
LinköpingAges 18–70 - NCT07329842Recruiting
Bed height and CPR quality in pediatric simulation
This trial tests how the height of a hospital bed affects chest compression quality and the physical strain on doctors during CPR on a child-sized manikin. It may help find the optimal bed height to improve CPR effectiveness.
Antalya, AntalyaAges 18 years+ - NCT07323667Enrolling by invitation
Study of a first responder system for cardiac arrest in Zug
This trial is studying a new system where trained volunteers respond quickly to help people whose heart stops outside of a hospital in Zug, Switzerland. The goal is to see if this system improves survival and recovery.
Zug, Canton of ZugAges 18 years+ - NCT06868888Recruiting
Red blood cell function in kidney failure
This study looks at how red blood cells work in people with end-stage kidney disease who are on hemodialysis. It aims to understand blood flow and may help guide future treatments.
TaoyuanAges 20 years+ - NCT07314138Recruiting
Comparing two minimally invasive heart bypass surgeries for three-vessel disease
This trial compares two types of heart bypass surgery for people with blockages in three main heart arteries. It tests a hybrid approach that combines a small incision bypass with a stent, versus a standard off-pump bypass. This may mean less recovery time for some patients.
Leuven, Vlaams BrabantAges 18–85 - NCT07281534Recruiting
Reliability of heart and lung exercise testing with ultrasound
This trial checks how reliable a heart and lung exercise test is when combined with an ultrasound of the heart. It may help doctors use this test more confidently for people with heart or lung conditions.
GenkAges Any age - NCT07286227Recruiting
Checking heart function before removing support tubes in heart surgery
This study compares two methods—visual checks and a special ultrasound of the heart—to see which better predicts how well the heart will pump after bypass machine support is removed during elective heart surgery.
ErzurumAges 18–75 - NCT03978377Recruiting
Checks heart and lung effects after chest radiation
This study looks at how chest radiation treatment affects the heart and lungs in people with certain lung or esophagus cancers. It may help doctors better predict and prevent these side effects during curative (aimed at cure) radiotherapy.

Common questions
- Are there clinical trials for cardiopulmonary?
- Yes. Clin2 currently lists 169 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.
