Tests coronary blood flow in heart failure patients with CRT
This study measures how well blood flows in the heart (coronary flow) in people with heart failure with reduced pumping strength and a specific heart rhythm problem called left bundle branch block. It focuses on people who already have a cardiac resynchronization therapy (CRT) device and have stable treatment, to see how coronary flow relates to their heart condition.

Score brain injury after cardiac arrest ICU admission
This study compares different scoring methods to estimate early brain injury when people are admitted to the ICU after a cardiac arrest. It may help doctors choose the best early assessment approach for patients who are in a coma.
Nantes, Pays de LoireAges 18 years+ - NCT05632432Recruiting
Heart tissue grafts to help the heart after surgery
This trial tests whether transplanting tiny heart “micrografts” from the left heart chamber area can improve heart function after cardiac surgery. It is meant for people with weakened heart pumping and heart failure symptoms despite medicine.
Helsinki, UusimaaAges 18–75 - NCT05643235Recruiting
Loop monitor to watch heart rhythms when starting a BTK inhibitor
This study checks how often abnormal heart rhythms happen when you start a BTK inhibitor (used for certain blood cancers). It uses a small implanted heart monitor to record your rhythm continuously before and after starting the medication, so doctors can detect and manage problems early.
New Hyde Park, New YorkAges 18 years+ - NCT05646849Recruiting
App-based support to keep exercising after heart rehab
This study tests whether a phone app can help people keep up physical activity after cardiac rehabilitation. If you can use a smartphone and internet, the app support may make it easier to stay active after your rehab program.
CholetAges 18 years+ - NCT05651945Recruiting
Cardiac rehab program for people after a stroke
This trial studies a supervised cardiac rehabilitation program for people after they have had a stroke. It may help improve heart-related fitness and recovery safety after stroke, especially for patients who need a tailored rehab approach.
Edison, New JerseyAges 18 years+ - NCT05659589Recruiting
Using a kidney toxin level to predict heart effects in AKI
This study looks at whether measuring indoxyl sulfate, a substance that can build up when kidneys are injured, can help predict how blood vessels and the heart are affected during acute kidney injury (AKI). It may help doctors understand who is at higher risk of heart-related problems while AKI is happening.
AmiensAges 18 years+ - NCT05664308Recruiting
Watch-based heart rhythm monitoring after heart surgery
This study tests whether a connected watch can help monitor an irregular heart rhythm (atrial fibrillation) after heart surgery. It looks at people who develop new atrial fibrillation after surgery and compares how well monitoring works over the next 12 months.
Nantes, Loire AtlantiqueAges 18 years+ - NCT05665608Recruiting
Prevent sudden death after a heart attack with a defibrillator
This trial studies whether implanting a defibrillator (ICD) soon after a heart attack can lower the risk of sudden cardiac death in people with weaker heart pumping and symptoms of heart failure. It compares strategies around defibrillator implantation, aiming to improve safety and outcomes.
FeldkirchAges 18 years+ - NCT05679739Recruiting
Caring for brain after cardiac arrest
This study tests a treatment approach aimed at protecting the brain and supporting better blood flow to the brain after a cardiac arrest. It may help some people who are in a coma right after the event recover more safely or with less brain injury.
SingaporeAges 21–79 - NCT05689385Recruiting
Online cardiac rehab after a heart attack you can do at home
This trial tests an eHealth (phone or internet-based) cardiac rehabilitation program for people after a heart attack, meant to help you recover with safer activity guidance. It may fit you if you’re not able to go to a rehab clinic in person.
TaipeiAges 20 years+ - NCT05732051RecruitingPhase 2
Nicotinamide riboside to protect the heart during breast cancer chemo
This trial tests whether nicotinamide riboside can help prevent heart problems caused by a common breast-cancer chemotherapy (anthracyclines). If you’re eligible, you’ll be followed to see how your heart is doing during treatment.
Lørenskog, AkershusAges 18 years+ - NCT05760287Recruiting
Study of heart ultrasound findings in cardiac amyloidosis
This study looks at how cardiac amyloidosis shows up on heart imaging, especially ultrasound (echocardiography). It may help doctors better describe and track the condition using your exam and test results.
Roma, RMAges 18 years+ - NCT05765175Recruiting
Radioablation versus repeat ablation for hard-to-treat VT
This trial compares a heart procedure using targeted radiation (called radioablation) to a repeat catheter ablation for people with high-risk, hard-to-control ventricular tachycardia (VT). It aims to find which approach is safer and works better after standard ablation and amiodarone have not stopped the abnormal rhythm.
Los Angeles, CaliforniaAges 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+ - NCT05788120Recruiting
Study heart rhythm problems in adults on VA ECMO
This study looks at how often abnormal heart rhythms happen and how serious they are in adults who are supported with VA ECMO for severe heart failure. It mainly involves using medical information, aiming to better understand complications in this critical situation.
AngersAges 18 years+ - NCT05797857Recruiting
Exercise program for transthyretin heart amyloidosis
This trial studies whether a structured exercise training program is safe and helpful for people with transthyretin (ATTR) cardiac amyloidosis. It may help improve fitness and daily functioning, and it may also compare groups for specific eligibility needs.
Boston, MassachusettsAges 60–90 - NCT05817929Recruiting
Angiopoietin levels and outcomes after heart bypass surgery
This study looks at how a blood protein called angiopoietin relates to recovery and complications after heart surgery that uses a heart-lung machine. If you’re having scheduled heart bypass-type surgery, your team may take blood samples to see whether these levels can help predict outcomes.
AmiensAges 18 years+ - NCT05817851RecruitingPhase 2
Vitamin C by vein after cardiac arrest shock
This Phase 2 study tests whether early high-dose vitamin C given through a vein can improve outcomes for people who remain unconscious after an out-of-hospital cardiac arrest with shock. It may help by supporting recovery during the time when the body is under severe stress.
AmiensAges 18 years+ - NCT05868616Recruiting
Checking heart resynchronization timing with a noninvasive test
This trial evaluates a noninvasive way to assess who should get Cardiac Resynchronization Therapy (CRT), and to check results after implantation. If you fit the heart rhythm and heart pump criteria, the approach may help confirm whether CRT is appropriate for you.
OsloAges 18–80 - NCT05873543Recruiting
Smartphone-based exercise program for heart failure recovery
This trial tests whether a hybrid heart-rehabilitation program that uses a smartphone helps people with heart failure feel better and safely exercise. If you’re eligible, you’ll likely get guided exercise training with help from a phone app.

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,318 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.
