Salt Lake City, UtahAges 18 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+ - NCT02413450Enrolling by invitation
Using patient DNA cells to study inherited heart rhythm risks
This study uses your blood or genetic information to make “iPS cells,” lab-grown cells that can help researchers study inherited heart rhythm problems like LQTS, Brugada syndrome, CPVT, or early repolarization syndrome. It may help improve understanding of why these rhythms happen and guide future treatments.
Baltimore, MarylandAges 18–85 - 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+ - 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 - NCT01725763Enrolling by invitation
MRI without contrast to help diagnose pulmonary hypertension
This study uses an MRI scan that does not use contrast dye to better diagnose and sort out pulmonary hypertension (high blood pressure in the lungs). It may help doctors classify your condition more accurately, especially around the time you’re scheduled for a right-heart catheterization.
Graz, StyriaAges 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+ - NCT07059962Recruiting
Sensor-based congestion alert for peritoneal dialysis
This study tests a new sensor system that can predict fluid overload (congestion) in people on peritoneal dialysis. It may help you and your care team spot problems early so you can avoid hospital visits.
Victorville, CaliforniaAges 21 years+ - NCT07118358Recruiting
Testing a new leadless pacemaker for slow heart rhythms
This trial studies a small, leadless pacemaker that is placed directly in the heart to treat slow heart rhythms. It's designed for people who need a pacemaker for the bottom chambers of the heart.
Burlingame, CaliforniaAges 18 years+ - NCT04141605Enrolling by invitation
Heart transplant candidates matched for better heart preservation
This study creates a worldwide registry and information database to help improve how donor hearts are preserved for transplant. If you are a heart transplant candidate, your details may be recorded to see what matching and preservation approaches work best.
Stanford, CaliforniaAges Any age - NCT06471036Recruiting
Improving cholesterol testing and treatment after a heart attack
This study tests whether giving extra education to doctors and patients can help improve cholesterol management after a heart-related hospitalization. It aims to see if a simple program can make sure patients get the right testing and treatment for high cholesterol.
Minneapolis, MinnesotaAges 18 years+ - NCT02381301Recruiting
Blood and heart CT scan tests for heart blood-flow markers
This study looks at whether certain lab “biomarkers” and a heart CT scan can help understand heart blood flow in people getting routine coronary CT angiography (CCTA). It may be useful for improving how doctors assess heart health from scan and blood results.
Maastricht, LimburgAges 18 years+ - NCT02488876Recruiting
Banking heart tissue samples after cardiac surgery
This study collects tissue samples from people who are having heart surgery and stores them in a database to better understand the body’s inflammatory (immune) response after surgery. Your participation may help researchers learn why inflammation happens and how to improve care after surgery.
