Recruiting studies
- 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+ - NCT02061787Recruiting
Exercise testing to assess outcomes in pulmonary hypertension
This trial studies how well a treadmill/breathing exercise test can measure health outcomes in people with certain types of pulmonary hypertension. It may help your care team judge your status and track changes over time.
BeijingAges 5–100 - NCT00493688Recruiting
Tracking energy changes during surgery in esophageal or lung cancer
This study looks at how your body uses energy during surgery and whether those patterns relate to how well you do after surgery. It may help doctors better predict outcomes for people with newly diagnosed esophageal or lung cancer who are preparing for treatment.
Houston, TexasAges 18 years+ - NCT02708134Recruiting
Study of CPR quality in children and young adults
This trial looks at how well CPR (chest compressions) is done during an emergency resuscitation in children and young adults. The goal is to understand what helps improve care during life-saving resuscitation.
Los Angeles, CaliforniaAges birth–18 years - NCT03204357Recruiting
Using your own blood after heart-lung machine surgery
This trial studies giving a “fresh” blood transfusion from your own blood after heart surgery that uses a heart-lung machine. It may help patients avoid needing donated blood, but it only works for people who meet specific safety and timing requirements.
Aurora, ColoradoAges 18–90 - 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 - 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+ - 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.
Samsun, AtakumAges 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+ - NCT07474090Recruiting
Personalized Exercise Program for Breast Cancer Survivors
This study tests whether a personalized exercise program during chemotherapy helps breast cancer survivors recover better and feel stronger. You'll use a smartphone app to do guided workouts at home while getting support from exercise coaches.
Winston-Salem, North CarolinaAges 18–85 - NCT07486791Recruiting
Baduanjin exercise for heart health after heart attack
This study tests whether a gentle exercise called 'Lying-Sitting-Standing' Baduanjin can improve heart and lung function and quality of life in people who have had a heart attack and also have heart failure.
Taiyuan, ShanxiAges Up to 85 years - NCT07573150Recruiting
Pupil Measurements to Predict Breathing Problems After Surgery in Children
This study tests whether measuring how a child's pupils (the dark circles in the eyes) respond to light can predict which children might have breathing problems after receiving pain medication during tonsil surgery. The goal is to help doctors catch and prevent serious breathing issues before they happen.
San Francisco, CaliforniaAges 3–17 - NCT07573683Recruiting
Breathing Exercises With Aerobic Activity for Early-Stage High Blood Pressure
This study tests whether combining special breathing techniques (coherent breathing) with aerobic exercise helps lower blood pressure and improve quality of life in people with stage 1 hypertension. You'll learn these techniques and perform them regularly to see if they work better together than exercise alone.
IslamabadAges 30–65 - NCT07641413Recruiting
How lungs and heart change over a lifetime of health
This study follows healthy adults over decades to understand how lung and heart function naturally change with age. Researchers will measure your breathing and heart health to help them spot early warning signs of disease in future patients.
San Francisco, CaliforniaAges 24–68 - NCT07331831Enrolling by invitation
CPR and AED skills after a training course
This study looks at how confident and skilled people are in performing CPR and using an AED after taking a standard training course. It aims to find out if the course helps people feel ready to act in an emergency.
Sofia, SofiaAges 12 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+ - NCT07130968Enrolling by invitation
Heart and lung function study with exercise test and five-year follow-up
This study looks at how your heart and lungs work during exercise by using a special test called a cardiopulmonary exercise test (CPET). Researchers will follow you for up to five years to see how your health changes. It may help you understand your heart condition better and get more personalized care.
Guangzhou, GuangdongAges 18–80 - NCT06747546Enrolling by invitation
Oxygen-based blood flow management after heart surgery
This study is testing a new way to manage blood flow after heart surgery in children with congenital heart disease. The goal is to make sure the body gets the right amount of oxygen to help recovery.
Minhang, Shanghai MunicipalityAges 1 week–18 years - NCT06602934Recruiting
Pneumonia, heart health, and your body's germs
This study looks at how pneumonia affects the long-term health of your heart and lungs by studying the germs that live in your body. It may help doctors understand why some people get worse and how to better protect your heart after a serious infection.
AngersAges 18–80 - NCT05388019Enrolling by invitation
VAD clinic visit study for new and returning patients
This trial looks at how well a specialized, multidisciplinary clinic works for people who have a ventricular assist device (VAD) and compares new VAD patients with those who have already had standard follow-up visits. It may help improve how care and check-ins are organized after your VAD is implanted.
Boston, MassachusettsAges 18 years+ - NCT04444362Enrolling by invitation
Probacine to protect organs after cardiovascular surgery
This study tests whether a medicine called Probacine can help protect your gut and organs after cardiovascular surgery. If you qualify, you may be asked to take part and follow the study plan to see if complications are reduced.

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.
