Using a blood test to guide antibiotics in aorta surgery
This trial checks if a blood test called presepsin can help doctors decide when to use antibiotics in patients having surgery on the chest's main artery (the thoracic aorta). It is for people with an aneurysm or tear in that artery.
Moscow, MoscowAges 18–75 - NCT04983823Recruiting
Study aims to improve long-term heart effects after COVID
This trial looks at how persistent heart-related changes after a past COVID infection may be affected by study treatments. It mainly seeks people who are stable enough for follow-up visits and heart imaging, and who are not already on the specific heart medications required.
Melbourne, VictoriaAges 50–85 - NCT05239364Recruiting
Ablation for an abnormal heart rhythm after prior AF surgery
This trial tests a procedure to “ablate” (treat) a specific fast heart rhythm in the upper chambers of the heart that happens after previous atrial fibrillation (AF) ablation or heart surgery. It may help by stopping the rhythm and reducing symptoms, while doctors check how well the targeted mapping and ablation work.
Hamburg, Free and Hanseatic City of HamburgAges 18 years+ - NCT07059962Recruiting

Toronto, OntarioAges 8–18 - NCT07405333Recruiting
Coughing exercises vs breathing device after heart surgery in children
This study compares simple coughing exercises with a breathing device (incentive spirometry) to help children recover lung function faster after heart surgery. It may help reduce complications and shorten hospital stays.
Baghdad, Baghdad GovernorateAges 6–18 - NCT02725060Enrolling by invitation
Study of autoimmune changes in postural tachycardia syndrome
This trial studies whether an autoimmune (immune system–related) process is involved in postural tachycardia syndrome (POTS), a condition where your heart rate rises when you stand. The study may help researchers understand what causes POTS and how it could be treated or monitored.
Oklahoma City, OklahomaAges 18–50 - NCT07770269Recruiting
Heart function and anesthesia depth during heart surgery
This study checks how well the heart works and how deep the anesthesia is during planned heart surgery where a heart-lung machine is used. It aims to improve safety and outcomes for patients.
ThessalonikiAges 18 years+ - NCT07660419Recruiting
Home cardiac rehab app for coronary plaque
This trial tests whether a smartphone-based home cardiac rehabilitation program can help slow or reverse plaque buildup in people with mild-to-moderate coronary artery narrowing. It may be an option if you have stable heart disease and can exercise at home with remote monitoring.
BeijingAges 18–70 - NCT06774326Recruiting
Spectral CT to check for heart damage from lymphoma treatment
This study uses a special type of CT scan called spectral CT to see if chemotherapy drugs called anthracyclines can cause heart damage in people with certain lymphomas. The goal is to catch any heart problems early by imaging the heart before, during, and after treatment.
BolognaAges 18 years+ - NCT06061822Recruiting
Testing AI for better heart MRI scans
This trial is testing a new artificial intelligence system that helps doctors take clearer, faster heart images using MRI. It aims to make heart scans more accurate and comfortable for patients.
LondonAges 18 years+ - NCT04556188Recruiting
Study to improve cardiac surgery services for rheumatic heart disease
This study looks at whether building a better, sustainable cardiac surgery service can reduce the burden of rheumatic heart disease. It focuses on patients who need cardiac surgery at a specific hospital during a training and research program.
Addis AbabaAges 14 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 - NCT07617844Recruiting
Advanced MRI imaging for heart disease diagnosis
This study uses advanced magnetic resonance imaging (MRI) scans to better understand and diagnose heart disease. If you have suspected or confirmed heart problems, this trial may help doctors get clearer pictures of your heart muscle and tissue to figure out what's causing your symptoms.
Hangzhou, ZhejiangAges 18 years+ - NCT07416279Recruiting
Can tiny bubbles replace catheters for heart pressure checks?
This trial tests if tiny ultrasound contrast bubbles can measure heart pressure, possibly replacing the need for catheter tubes. If you're already getting a heart catheterization, you may be able to join.
LondonAges 21–81 - NCT06325280Recruiting
Exercise MRI for Kids with Heart Conditions
This study uses an MRI while exercising to check heart and lung fitness in children with heart disease. It helps doctors learn more about how to care for kids who have had a heart transplant or were born with heart problems.
Edmonton, AlbertaAges 10–18 - NCT07262580Enrolling by invitation
Finding meaning in cardiac rehab: a study
This study tests a program to help people in cardiac rehabilitation find personal meaning and purpose. It explores if the program works in individual, group, or paired sessions with a relative.
Odense, Region SyddanmarkAges 18 years+ - NCT02488876Recruiting
Banking heart tissue samples after cardiac surgery
This study collects tissue samples from people who are having heart surgery and stores them in a database to better understand the body’s inflammatory (immune) response after surgery. Your participation may help researchers learn why inflammation happens and how to improve care after surgery.
Aachen, North Rhine-WestphaliaAges Any age - NCT06290154Recruiting
Heart health after liver transplant study
This study looks at factors that affect heart health after a liver transplant. It may help doctors better predict and manage heart problems in people with end-stage liver disease who are getting a new liver.
Guangzhou, GuangdongAges 18 years+ - NCT07661940RecruitingPhase 2
SP16 for kidney protection during heart surgery
This trial tests a drug called SP16 to see if it can prevent acute kidney injury in people with chronic kidney disease who are having elective heart surgery with a heart-lung machine. It aims to help preserve kidney function after surgery.
Erlangen, BavariaAges 18 years+ - NCT05140434Recruiting
Check whether exercise heart tests help diagnose artery blockage
This study looks at whether an “exercise heart test” can better diagnose blockage in the heart’s coronary arteries. Participants may also have a heart scan or imaging test for comparison, within a short time window.

Common questions
- Are there clinical trials for cardiac disease?
- Yes. Clin2 currently lists 313 recruiting cardiac disease 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 disease 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 disease 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.
