Recruiting studies
- 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.

AI software to guide heart rhythm ablation treatment
This study tests new AI software (Volta AF-Xplorer II) that helps doctors guide catheter ablation—a procedure to treat irregular heartbeats like atrial fibrillation. The software may help doctors perform the procedure more effectively and safely in real-world settings.

Heart Device Detected Irregular Heartbeats: Treatment Study
This study follows patients who have a heart rhythm device (pacemaker, defibrillator, or resynchronization device) and have experienced brief episodes of fast irregular heartbeats detected by the device. The study compares treatment approaches to understand which helps patients stay healthier and feel better.
TaipeiAges 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.

Heart surgery recovery registry study
This study collects information from people having heart surgery to help doctors learn more about recovery. If you are scheduled for surgery during the study period, you may be able to join.
Hangzhou, ZhejiangAges Any age - NCT07549243Enrolling by invitation
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+ - NCT07349914Enrolling by invitation
Shoulder Pain and Function with Heart Devices
This study looks at shoulder pain and how well the shoulder works in people who have a heart device like a pacemaker. It aims to understand if having the device affects shoulder function over time.
Ankara, SamanpazariAges 18 years+ - NCT07253909Enrolling by invitation
Arm function in heart failure with ICD or CRT devices
This study looks at how well people with heart failure and certain heart devices (ICD or CRT) can use their arms and hands. It aims to understand if these devices affect upper body function.
Ankara, SamanpazarıAges 18 years+ - NCT07240714Enrolling by invitation
Web-based support for cardiac arrest survivors
This study tests a web-based support program for people who have survived a cardiac arrest. It aims to help you with recovery by providing online tools and information.
LinköpingAges 18 years+ - NCT07238426Enrolling by invitation
Heart screening for older adults in Ordu, Turkey
This study is a screening program in Ordu, Turkey, to find older adults (65+) who might have a heart condition called cardiac amyloidosis. It uses medical records and heart ultrasounds to check people who already have certain heart problems.
Ordu, OrduAges 65 years+ - NCT07236398Enrolling by invitation
Modified left atrial maze procedure for atrial fibrillation
This trial tests a modified maze procedure to treat atrial fibrillation during heart surgery. It may help patients with AFib who are already scheduled for cardiac surgery.
Toulouse, French (France)Ages 18 years+ - NCT07130968Enrolling by invitation
Heart and lung function study with exercise test and five-year follow-up
This study looks at how your heart and lungs work during exercise by using a special test called a cardiopulmonary exercise test (CPET). Researchers will follow you for up to five years to see how your health changes. It may help you understand your heart condition better and get more personalized care.
Guangzhou, GuangdongAges 18–80 - NCT07103863Enrolling by invitation
Imaging test for predicting AL cardiac amyloidosis outcomes
This study uses two types of imaging (PET/CT and MRI) to see if they can better predict outcomes for people with AL cardiac amyloidosis. The goal is to improve how doctors understand and manage the disease.
Beijing, Beijing MunicipalityAges Any age - NCT07034170Enrolling by invitation
Muscle mass and recovery after cardiac arrest
This study looks at how muscle mass affects recovery after a cardiac arrest (when the heart stops). It is for people who stay on a breathing machine in the ICU for more than three days. Researchers will measure muscle to see if it helps predict recovery.
TaipeiAges 18–99 - NCT06964152Enrolling by invitation
AI-Guided Mapping for Ventricular Tachycardia Ablation
This trial uses artificial intelligence to analyze heart images and guide doctors during a procedure to stop dangerous fast heart rhythms called ventricular tachycardia.
La Jolla, CaliforniaAges 21–90 - NCT06412432Enrolling by invitation
Exercise and rehab for heart amyloidosis
This study tests whether a supervised exercise and rehabilitation program can help people with a specific type of heart amyloidosis (ATTRwt) feel better and improve their heart function. It may be a good fit if you have stable heart failure and can safely exercise.
NaplesAges 18 years+ - NCT05830422Enrolling by invitation
Predicting late thinking problems after cardiac arrest
This study looks at how to predict delayed cognitive (thinking) impairment in people who survived a cardiac arrest but initially seemed neurologically okay. It may help identify who is at higher risk so follow-up and support can be planned earlier.
Daejeon, Seo-guAges 18 years+ - NCT03360227Recruiting
Registry after heart device implantation planning
This is a registry study that records information from people before they get a heart-related device implanted. It may help doctors understand how the team’s tests and planning relate to the procedure and outcomes later on.
DüsseldorfAges 18–80 - NCT06578104Recruiting
Pulsed AF Study: PulseSelect Catheter for Afib
This study tests a new way to treat atrial fibrillation (Afib) using a special catheter system called PulseSelect that delivers short bursts of energy to create scar tissue in the heart. It is for people whose Afib comes and goes or stays for a while but not more than a year, and who have not had a prior ablation procedure or have a pacemaker or defibrillator.
Tampa, FloridaAges 18 years+ - NCT06080074RecruitingPhase 2
Emergency heart-lung machine study for children with severe heart failure
This study tests a specific heart-lung machine called Cardiohelp to help children with severe heart failure. It looks at how well the machine works and whether a blood thinner (either heparin or bivalirudin) is safer and more effective.

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.
