Recruiting studies
- NCT07621055Recruiting

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 - NCT07609680Recruiting
Blood Pressure vs. Heart Output Monitoring During Colon Surgery
This trial compares two ways doctors monitor your body's circulation during colorectal surgery. One method tracks blood pressure; the other tracks how much blood your heart pumps. Researchers want to see which approach leads to better outcomes and fewer complications.
Ankara, Yenimahalle\AnkaraAges 18–80 - NCT07596446Recruiting
Emergency treatment study for cardiac arrest patients
This study tests emergency treatments for people who have had a cardiac arrest (heart stops beating) outside the hospital. It looks at two groups: people whose hearts stop despite CPR efforts, and people whose hearts have restarted. The goal is to see if these treatments can help patients survive and recover better.
PragueAges 18–70 - NCT07603336Recruiting
Heart Monitoring Methods During Pancreas Surgery
This study compares two ways of monitoring your heart function during Whipple surgery (pancreas removal). Doctors will use different monitoring approaches to guide fluid and medication during your operation to help you recover better.

Arm Exercise Training for Heart Failure With Device
This study compares different types of arm exercises for people with heart failure who have a pacemaker or defibrillator implanted. The goal is to see which exercise approach best improves how well your arms function and help you stay active.
ÇorumAges 18 years+ - NCT07588425Recruiting
Monitoring heart health during breast cancer treatment
This study watches how chemotherapy and HER2-targeted drugs affect your heart during early-stage breast cancer treatment. Researchers use heart scans to catch any changes early and understand how to protect heart health.
Ankara, AnkaraAges 18 years+ - NCT07583823Recruiting
Higher-Rate Pacing for Heart Amyloid Disease
This study tests whether pacing your heart at a faster rate helps people with cardiac amyloidosis (a condition where abnormal protein builds up in the heart). If you have a pacemaker and cardiac amyloidosis, this research might help doctors understand the best pacing settings for you.
Minneapolis, MinnesotaAges 18 years+ - NCT05778981Recruiting
Study of blood-vessel health during non-heart surgery
This study looks at how blood-vessel function changes around the time of non-heart surgery, especially in people 45 and older. It may help doctors better understand risks and recovery related to blood-vessel stress during hospitalization.
Independencia, Santiago MetropolitanAges 45 years+ - NCT07572435Recruiting
Remote Heart Exercise Program for Kids With Heart Surgery
This study tests whether kids aged 8–18 who had complex heart surgery can safely improve their fitness and well-being using exercise activities at home through a mobile app or video. The goal is to help them become more active after surgery.
SeoulAges 8–18 - NCT06044922Recruiting
Using heart rate to predict brain injury after cardiac arrest
This study looks at how your heart rate changes (heart rate variability) to predict brain injury after a cardiac arrest. It may help doctors identify brain damage earlier so they can provide better care.
Brest, Brittany RegionAges 18 years+ - NCT07564778Recruiting
Pain Management After Cardiac Arrest Recovery
This study examines how to better treat pain in patients who have survived cardiac arrest and are unconscious in the hospital. Researchers want to understand pain experiences and test pain-relief strategies during early recovery.
HalmstadAges 18 years+ - NCT07564531Recruiting
Safe sedation for heart catheterization in children
This study tests whether a combination of two sedative medications (dexmedetomidine and ketamine) works safely and effectively to keep children calm and still during heart catheterization—a procedure where a thin tube is guided through blood vessels to the heart for diagnosis or treatment.
HanoiAges Up to 18 years - NCT06735521Recruiting
Heart MRI stress test for Fontan circulation
This study uses a special heart MRI with a medicine that stresses the heart (like exercise) to look at blood flow in people who have had the Fontan surgery. The goal is to better understand how the heart works after this surgery.
StockholmAges 18 years+ - NCT07549841RecruitingPhase 2
Heart imaging study for transthyretin amyloidosis
This study tests a new type of heart imaging scan called [68Ga]Ga-FAPI-46 PET to help doctors see and track transthyretin cardiac amyloidosis (a disease where abnormal proteins damage the heart). The scan may help identify which patients are getting worse.
NantesAges 18 years+ - NCT07549243Recruiting
Ear Nerve Stimulation to Protect Kidneys During Heart Surgery
This trial tests whether gentle electrical stimulation applied to your ear can help protect your kidneys during heart surgery that uses a heart-lung machine. Kidney damage after this type of surgery is common, and researchers want to see if this non-invasive stimulation can prevent it.
Hangzhou, ZhejiangAges 18 years+ - NCT07549477Recruiting
Heart imaging study for cancer patients with catheter clots
This study uses a special heart imaging test (cardiac MRI) to look for and understand blood clots that may form around central catheters (tubes placed in veins) in people with cancer. The imaging helps doctors see if clots are present and what type they are, which could improve how they care for cancer patients.
Basking Ridge, New JerseyAges 18 years+ - NCT06744361RecruitingPhase 2
Ketamine after cardiac arrest to protect the brain
This trial tests whether the sedative drug ketamine, given after a cardiac arrest, can help protect the brain. It's for people whose heart stopped outside the hospital due to a shockable rhythm and who needed a breathing tube placed by emergency responders.
CopenhagenAges 18 years+ - NCT06739239Recruiting
French cohort study of an extra-vascular ICD

ParisAges Any age - 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.

Home vs. Hospital Heart Rehab After Heart Attack
This study compares two ways to do cardiac rehabilitation (heart exercise and education programs) after a heart attack: one done at home via telehealth (video visits) and one at a clinic. The goal is to see which approach works better and is easier for patients to stick with.

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,291 recruiting cardiac 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 cardiac 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 cardiac 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.
