Finding brain injury with a portable MRI after cardiac arrest
This study uses a portable MRI machine to look for brain injury in people who remain unconscious after their heartbeat is restored (ROSC) from a cardiac arrest. If you are having a standard MRI and being treated with temperature control, you may be eligible.
New Haven, ConnecticutAges 18 years+ - NCT07201363Recruiting
Inflammation and scarring markers after TAVI
This study looks at markers of inflammation and scarring in people who develop heart rhythm problems after having a TAVI procedure (a minimally invasive valve replacement). It may help doctors understand and predict these complications.

Improving heart health in prostate cancer patients on hormone therapy
This study tests whether combining a time-restricted eating plan, a heart-healthy diet, and a weight-loss medication (GLP-1 receptor agonist) can help improve heart health and weight in men with prostate cancer who are receiving hormone therapy. It aims to reduce the risk of heart problems caused by hormone treatment.
Duarte, CaliforniaAges 30–79 - NCT07205341Recruiting
Artery blood flow monitoring during heart valve procedure
This study is testing a new way to monitor blood flow and heart function during a valve replacement procedure. It may help doctors track how well the heart is pumping.
Boulder, ColoradoAges 18–80 - NCT07215715Recruiting
Heart ultrasound study for older adults with heart failure
This study uses a special ultrasound to measure heart stiffness in people 60 and older who have heart failure with preserved or mildly reduced pumping function, with or without a condition called ATTR amyloidosis (a protein buildup in the heart). It also includes healthy controls.
Boston, MassachusettsAges 60 years+ - NCT07217392Recruiting
Study on pacing the left bundle branch area of the heart
This study tests a new way to place a pacemaker lead in the left bundle branch area of the heart. It may help people who need a pacemaker to see if this approach is safe and works well.
Rio de Janeiro, Rio de JaneiroAges 18 years+ - NCT07218705Recruiting
MCG scan study for cardiac amyloidosis
This study uses a new type of heart scan (MCG) to help understand cardiac amyloidosis. It may help doctors learn more about the condition without needing invasive tests.
Rochester, MinnesotaAges 18 years+ - NCT07232459Recruiting
PET imaging for amyloidosis in the heart
This study tests a new PET imaging tracer called [18F]FT8 to see if it can better detect amyloid protein buildup in the heart. It may help doctors diagnose and monitor cardiac amyloidosis more accurately.
Hefei, AnhuiAges 18 years+ - NCT07235709Recruiting
Study of agalsidase alfa for heart inflammation in Fabry disease
This trial tests whether agalsidase alfa can reduce heart inflammation in people with Fabry disease who have heart problems. You may qualify if you have not had this treatment in the past year.
SeoulAges 15–75 - NCT07238400RecruitingPhase 2
Heart medication study for women after preeclampsia
This study tests if a medication called a mineralocorticoid receptor antagonist (MRA) can help improve heart function in women who had preeclampsia and now have high blood pressure and signs of heart thickening.
Boston, MassachusettsAges 18–65 - NCT07238920Recruiting
Brain training for heart health in people with coronary artery disease and anxiety
This trial tests a brain-training technique called neurofeedback, which uses a video game controlled by your brain activity to help your heart and nervous system work better. It is for people with both coronary artery disease and anxiety who want to improve their heart health and manage anxiety without medication.
Shenyang, LiaoningAges 18 years+ - NCT07239206Recruiting
Serious game for ICU nurses on temperature management
This study tests whether a serious game (an educational game) can help critical care nurses learn more about targeted temperature management (cooling or warming the body to protect the brain) and improve their ability to notice and react to patient changes. You would play the game and take tests before and after to see if it works.
Taipei, TaipeiAges 20 years+ - NCT07240441Recruiting
Comparing heart ablation methods for post-heart attack VT
This trial tests two ways to do a heart procedure (ablation) in people who have had a heart attack and now have dangerous fast heart rhythms. It compares the usual method (inside the heart only) with a method that also works on the outer surface of the heart. The goal is to see which works better to stop these rhythms.
Warsaw, Masovian VoivodeshipAges 18–85 - NCT07244484Recruiting
Brain Training for Heart Health in Coronary Artery Disease with Anxiety
This trial tests a brain training technique (neurofeedback) to help people with coronary artery disease and anxiety. It aims to improve heart rate control by targeting a specific brain area.
Shenyang, LiaoningAges 18 years+ - NCT07245069RecruitingPhase 2
Can dapagliflozin protect the heart during breast cancer chemo?
This trial tests if the drug dapagliflozin can prevent heart damage caused by anthracycline chemotherapy in breast cancer patients. It aims to see if taking the drug during chemo helps keep your heart healthy.
LjubljanaAges 18 years+ - NCT07246135Recruiting

Noninvasive blood pressure monitoring during aneurysm repair
This study compares a new noninvasive blood pressure monitoring method to the standard method (using a small tube in your wrist) during brain aneurysm repair surgery. If you join, you may avoid the need for a wrist artery line.
SeoulAges 19–80 - NCT07247669Recruiting
AI phone triage for emergencies

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,309 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.
