Testing a drug to prevent kidney injury after heart surgery
This study tests a new medicine, BX-001N, to see if it can prevent kidney damage during and after heart surgery for aortic disease. It is for people with moderate kidney problems who are having planned surgery that stops the heart briefly.
DaeguAges 19–90 - NCT07531602Enrolling by invitation
How breathing pressure affects heart function during surgery
This study observes how different levels of breathing support during heart surgery affect your heart's function. Researchers will use ultrasound and monitoring tools already planned for your surgery to see how small changes in breathing pressure impact your heart's performance.
Boston, MassachusettsAges 18 years+ - NCT07351656Recruiting
Using AI and ultrasound to screen for heart disease
This study uses AI to analyze heart tracings (ECGs) and focused ultrasound images to detect heart disease early. It includes teenagers, young adults, adults over 30, and pregnant women.
Rochester, MinnesotaAges 15 years+ - NCT07374289Recruiting
CPR and life support before hospital in Ostrava
This trial is testing a way to start CPR and emergency life support (ECPR) at the scene of a cardiac arrest in Ostrava. It might help if you or a loved one has a witnessed cardiac arrest that is likely caused by a heart problem, and you're under 70 years old.
Ostrava, Moravian-Silesian RegionAges 18–70 - NCT07385092Recruiting
Continuous monitoring after non-cardiac surgery
This trial compares continuous vital sign monitoring with standard spot checks for patients recovering from non-cardiac surgery. It aims to see if constant monitoring can improve safety and outcomes.
Hamburg, Free and Hanseatic City of HamburgAges 45 years+ - NCT07391683Recruiting
Heart failure support before heart surgery
This trial tests if special remote care before heart surgery can improve recovery for people with heart failure. You will have regular check-ins by video or phone to help manage your health before your operation.
Innsbruck, TyrolAges 18 years+ - NCT00921986Recruiting
Store heart rhythm samples for arrhythmia research
This study builds a bank of stored heart rhythm-related samples so researchers can study different heart rhythm problems. It may help you or your family contribute to future testing and better care for arrhythmias.
Cleveland, OhioAges 18 years+ - NCT00733590Recruiting
Study after ICD generator replacement for heart attack patients
This study follows people who had a prior heart attack and later received a replacement ICD (a device that helps prevent sudden dangerous heart rhythms). It is observational, meaning it mainly looks at outcomes and device-related information rather than testing a new drug.
Washington D.C., District of ColumbiaAges 18–85 - NCT01477359Recruiting
Sarcoidosis and the heart: a long-term study
This study follows people with sarcoidosis that may or may not be affecting the heart. It uses special scans (PET and MRI) to look for heart involvement and track how the disease changes over time.
Calgary, AlbertaAges 18–99 - NCT00181233Recruiting
MRI imaging to assess sudden heart risk factors
This study tests heart imaging (using MRI) to better identify factors linked to sudden cardiac death risk. You may be eligible if you have reduced heart pumping ability and are planning a specific heart device to prevent dangerous heart rhythms.
Baltimore, MarylandAges 18 years+ - NCT01390675Recruiting
Registry for heart valve replacement anesthesia during TAVR
This study tracks patients who get a transcatheter aortic valve implantation (TAVR), a procedure to replace a narrowed heart valve without open-heart surgery. It looks at the type of anesthesia used during the procedure and records outcomes to learn what works best for patients.
Munich, BavariaAges 18 years+ - NCT01258231Recruiting
Genetic test to predict risks after heart surgery
This study looks for genetic (DNA) clues that may help predict side effects or complications after heart surgery. If you join, your genome information may be used to understand who is at higher risk and why.
Boston, MassachusettsAges 20–90 - NCT00573339Recruiting
Heart MRI test in women with normal heart testing
This trial uses heart MRI scanning to create normal reference measurements in women who appear to have no heart blood-flow problems. It may help doctors compare future MRI results and better interpret scans when symptoms happen.
Los Angeles, CaliforniaAges 35–65 - NCT02664831Recruiting
Study of inflammation after cardiac arrest in ICU patients
This trial looks at how the body’s inflammation response behaves after someone has a cardiac arrest and was treated in the ICU. It may help doctors understand which patients could benefit from treatments that target harmful inflammation after resuscitation.
Portland, MaineAges 18 years+ - NCT02798705Recruiting
Testing heart tiny blood vessel function in amyloidosis
This study measures how well the heart’s tiny blood vessels work in people with cardiac amyloidosis, using special heart testing. It may help doctors understand the disease better and improve how patients are evaluated over time.
SeoulAges 18–85 - NCT02855554Recruiting
MRI heart scan study for specific heart conditions
This study uses a special MRI approach to measure details of your heart muscle in people with certain heart problems. It may help researchers better understand how different conditions affect the heart and how those changes can be measured.
Charleston, South CarolinaAges 18–90 - NCT02781922RecruitingPhase 3
Stem cell infusion for single-ventricle heart failure during surgery
This trial tests whether an infusion of heart stem/progenitor cells can improve outcomes for children with a single working heart chamber (single ventricle) who are scheduled for the next surgical stage (Glenn or Fontan). It may help the heart function after surgery, but participation depends on several heart, lung, brain, and overall health safety criteria.
KanagawaAges birth–6 years - NCT02845531RecruitingPhase 4
Defibrillator device vs medicines for a rare heart spasm after arrest
This trial compares an implantable defibrillator device plus best care versus best medicines alone in people who survived a cardiac arrest caused by a specific abnormal heart rhythm. It focuses on variant angina, where a heart-spasm problem can trigger dangerous rhythm events, to see which approach prevents future events.
Bucheon-siAges 18 years+ - NCT02582021Recruiting
Study of treatments and imaging in women with angina or HFpEF
This trial studies how heart disease affects the heart using heart imaging, and looks at people with chest pain/angina or heart failure with preserved pumping strength (HFpEF). It may help doctors better understand what’s driving symptoms and how best to evaluate these conditions.
Los Angeles, CaliforniaAges 18 years+ - NCT03238690Recruiting
LVAD conditioning to help your heart recover
This study looks at an approach called “conditioning” using your LVAD (a heart pump) while you wait for a transplant. It aims to see whether your heart muscle may recover better during planned changes in support.
Salt Lake City, UtahAges 18 years+ - NCT04880265Recruiting

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,308 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.
