Apiban to Help Dialysis Fistulas Mature Successfully
This trial tests whether a blood-thinner medication called apixaban (Apiban) helps arteriovenous fistulas—surgically created connections in the arm for dialysis—develop and work better. If it helps fistulas mature faster and more reliably, it could reduce complications and improve treatment for kidney failure patients.

Pacemaker Pacing Strategies for Heart Failure Patients
This study tests whether optimized pacemaker settings can improve heart function and symptoms in heart failure patients who need a pacemaker for a slow heartbeat. The goal is to find the best way to program the pacemaker to help your heart work better.
Seoul, SeoulAges 19 years+ - NCT07563257Recruiting
Comparing Two Mapping Catheters for Heart Rhythm Ablation
This trial compares two types of specialized catheters used during heart rhythm ablation procedures to help doctors confirm they've created the right burn patterns. If you're having ablation for persistent atrial fibrillation or flutter with complex burn lines planned, this trial may help improve how your procedure is done.

Nicotinamide Riboside for Combined Pulmonary Hypertension
This study tests whether nicotinamide riboside (a B-vitamin supplement) can help people with combined pulmonary hypertension—a condition where blood pressure in the lungs is too high. The researchers want to understand how this supplement affects the body's energy metabolism and whether it might reduce symptoms and improve heart function.
Nashville, TennesseeAges 18–85 - NCT07563608Recruiting
Understanding High Blood Pressure in the Lungs for Dialysis Patients
This study investigates why some dialysis patients develop high blood pressure in their lung blood vessels and how it affects their health. Researchers will assess heart function and follow patients over time to better understand this condition.
Pavia, LombardyAges 18–75 - NCT07563660Recruiting
Heart imaging study for arrhythmogenic right ventricular cardiomyopathy
This study uses a special type of heart scan (FAPI PET/CT) to better visualize and understand arrhythmogenic right ventricular cardiomyopathy (ARVC), a condition where the heart muscle weakens and causes irregular heartbeats. The scan may help doctors understand the disease better and improve patient care.
Istanbul, FatihAges 18 years+ - NCT07563777Recruiting
Long-term study of human aging and health
This is a long-term research study that follows people over time to understand how humans age. Researchers will collect information about your health and lifestyle to learn what helps people stay healthier as they get older.
Boulder, ColoradoAges 18 years+ - NCT07564219Recruiting
Beta-Hydroxybutyrate to Boost CAR-T Cell Therapy in Multiple Myeloma
This trial tests whether a natural metabolite called beta-hydroxybutyrate can strengthen CAR-T cell therapy (a type of cancer-fighting cell treatment) in multiple myeloma patients. The goal is to help your immune cells work better against your cancer.
Hamburg, Free and Hanseatic City of HamburgAges 18 years+ - NCT07564778Recruiting
Pain Management After Cardiac Arrest Recovery
This study examines how to better treat pain in patients who have survived cardiac arrest and are unconscious in the hospital. Researchers want to understand pain experiences and test pain-relief strategies during early recovery.
HalmstadAges 18 years+ - NCT07565363Recruiting
Motor Imagery Training for Stroke Arm Recovery
This study tests whether imagining arm movements (without actually moving) can help improve arm function in people recovering from stroke. Participants will practice visualizing movements to see if it helps restore strength and control in their affected arm.
IstanbulAges 18 years+ - NCT07565805Recruiting
Heart Imaging Registry Comparing Two Scanning Methods
This study compares two different ways of taking detailed pictures of your heart arteries: a CT scan and an optical scan done during a heart catheterization. The researchers want to understand how well these two methods show blockages in your arteries.
BernAges Any age - NCT07566598Recruiting
Brain Blood Flow Measurement After Stroke Treatment
This study measures how well blood flows through the brain after a special procedure to remove a blood clot causing stroke. Researchers use a tiny temperature sensor to understand blood circulation, which may help improve stroke care.
Nice, Alpes-maritimesAges 18–80 - NCT07568795Recruiting
Testing a portable electronic stethoscope for heart valve disease
This study validates a new portable electronic stethoscope that can help detect heart valve disease. If you've had an echocardiogram (heart ultrasound) recently, researchers want to test whether this device accurately identifies valve problems.
Hong Kong, Pok Fu Lam Rd.Ages 18 years+ - NCT07569016Recruiting
Monitoring Brain Activity During Heart Rhythm Treatment
This trial compares two ways of giving sedation (sleepy medicine) during a procedure to restore normal heart rhythm in people with atrial fibrillation. One method uses a special brain monitor to guide sedation doses, while the other uses standard clinical judgment. The goal is to see if the brain monitor helps keep you safer and more comfortable.
