Heart rhythm genetic registry and blood sample bio bank
This study is building a Canadian database and tissue/blood bank for people and families with inherited heart rhythm conditions (and some inherited heart muscle diseases). It collects consented health and genetic information to help researchers better understand who is at risk and how these conditions work.
Vancouver, British ColumbiaAges Any age - NCT03588286Recruiting
Check heart rhythm risk early after a heart attack
This trial tests whether a programmed heart rhythm test can better identify who needs an implanted defibrillator (ICD) soon after a heart attack. It may help prevent dangerous fast heart rhythms (tachyarrhythmias) by guiding who gets an ICD.
Boston, MassachusettsAges 18–85 - 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 - NCT03775954Recruiting
Fetal heart testing in high-risk pregnancies after baby loss
This study checks unborn babies’ heart signals using special scans during pregnancy and then checks the baby’s heart shortly after birth. It may help researchers understand why certain high-risk pregnancies can lead to fetal demise and improve care.
Madison, WisconsinAges 18 years+ - NCT06813443Recruiting
Studying cardiomyopathy to find who needs a heart transplant
This study is looking at people with cardiomyopathy to understand which patients are most in need of a heart transplant. By joining, you will help doctors learn more about critical cases and improve care for heart muscle disease.
Bologna, Emilia-Romagna/BolognaAges 12 years+ - NCT05236153Recruiting
Study of heart valve procedure in repaired Tetralogy of Fallot
This study looks at how a transcatheter pulmonary valve replacement works in people with repaired Tetralogy of Fallot or double outlet right ventricle. The goal is to better understand the heart’s anatomy and how it may affect the valve procedure.
Boston, MassachusettsAges Any age - NCT05390047Recruiting
Register people with an S-ICD and follow them after implant
This trial is a registry that collects real-world information from people who receive an S-ICD (a small device under the skin) to help doctors learn how these devices perform over time. You may qualify if you already had the implant and can be followed for at least one month.
Lübeck, Schleswig-HolsteinAges 18–99 - NCT06089902Recruiting
European registry for anomalous aortic origin of coronary arteries
This is a European registry for people with an anomalous origin of a coronary artery from the aorta (AAOCA). It will track how the condition is treated—whether with surgery or monitoring—to learn what works best.
Padova, PDAges Any age - NCT06546137Recruiting
Registry for inherited heart conditions in Brazil
This study is building a national registry in Brazil to learn more about inherited heart conditions and improve care. If you have a family-related heart disease, you may be able to join and help advance cardiovascular healthcare.
Rio Branco, AcreAges Any age - NCT06705751Recruiting
Faster diagnosis of abnormal coronary artery origin
This study tests a new, faster way to diagnose an uncommon heart condition where one of the main arteries (the coronary artery) starts from the wrong place on the aorta. The goal is to help doctors find and treat it sooner.
San Donato Milanese, ItaliaAges 6 years+ - NCT06771700Recruiting
S-ICD implantation study for heart patients
This study looks at implanting a type of ICD (implantable cardioverter-defibrillator) called a subcutaneous ICD, or S-ICD, which goes under the skin instead of in the heart. It is designed to help see how well this works in standard care.
Cologne, North Rhine-WestphaliaAges Any age - NCT06857838Recruiting
Bypass surgery for symptomatic myocardial bridge
This trial tests whether bypass surgery is effective for people with a myocardial bridge (a heart muscle that arches over an artery) that still causes symptoms despite medication. It aims to see if surgery can improve symptoms and outcomes.
Xi'an, ShaanxiAges 18–80 - NCT06954103Recruiting
Stroke and heart health study for recent stroke patients
This study looks at how a moderate to severe stroke can affect your heart. It aims to understand the link between stroke and heart problems, which may help improve future care.
Wuhan, HubeiAges 18 years+ - NCT06964464RecruitingPhase 4
Comparing two heart failure medications in ICD patients
This trial compares two beta-blocker medications, carvedilol and metoprolol succinate, to see which one works better for people with heart failure who have an implantable cardioverter defibrillator (ICD). If you are currently taking metoprolol succinate, you may be able to switch to carvedilol and help researchers find the best treatment.
Scottsdale, ArizonaAges 18 years+ - NCT07020702Recruiting
Predicting sudden cardiac death risk in heart muscle disease
This study looks at how the heart's electrical signals can predict sudden cardiac arrest in people with a weakened heart muscle. It may help doctors identify who is at highest risk.
Clermont-FerrandAges 18–80 - NCT07372196Recruiting
Left bundle branch pacing after myectomy for hypertrophic cardiomyopathy
This trial is testing a new way to pace the heart (left bundle branch pacing) for people with hypertrophic cardiomyopathy who still have a dangerous heart rhythm problem after myectomy surgery. It aims to see if this pacing can reduce the risk of sudden cardiac death.
Novosibirsk, Novosibirsk OblastAges 18–75 - NCT01076660Recruiting
MRI study to predict sudden cardiac death risk
This trial uses heart MRI images and measurements to look for warning signs that could predict sudden cardiac death. It focuses on people with significantly reduced heart pumping function who are being considered for an ICD to prevent sudden death.
Newark, DelawareAges 21–80 - NCT06464315Enrolling by invitation
VT Ablation Guided by Scar Tissue Only
This trial tests a new approach to treating a dangerous heart rhythm called ventricular tachycardia (VT) in people with scarred heart muscle. The goal is to use only the scarred area to guide the ablation procedure, which may make it safer and more effective.
San Diego, CaliforniaAges 18–90 - NCT07174986RecruitingPhase 2/Phase 3
Double defibrillation for out-of-hospital cardiac arrest
This trial tests whether giving two shocks in a row (instead of one) helps restart the heart in people who have a cardiac arrest outside the hospital and need a defibrillator.
AmsterdamAges 18 years+ - NCT07009652Recruiting
Optimizing mobile ECMO for sudden cardiac arrest patients
This trial tests a better way to get a mobile team that can start ECMO (a heart-lung machine) to people who have a sudden cardiac arrest outside the hospital. The goal is to see if this approach can help save more lives in certain regions.
