Testing a Blood Pressure Bracelet for Daily Monitoring
This study tests whether wearing an Aktiia bracelet for 6 months can help doctors better understand and control your blood pressure. You'll wear the bracelet daily and visit the clinic twice to see if this wearable device helps manage high blood pressure that isn't controlled by current medications.

Dual-Target CAR-T Cells for Blood Cancers That Haven't Responded to Treatment
This study tests a new type of cell therapy called CAR-T cells that are designed to target two different proteins on cancer cells. These cells are made from your own immune cells, trained in the lab, and then put back into your body to fight blood cancers that have come back or stopped responding to previous treatments.

Huntsville, AlabamaAges 18–80 - NCT07523750Recruiting
Pulsed field ablation for persistent atrial fibrillation
This study tests two types of pulsed field ablation catheters to treat persistent atrial fibrillation, a heart rhythm problem lasting more than 7 days but less than a year. The goal is to see if these catheters can safely and effectively restore a normal heart rhythm.

Testing diabetes heart medicine soon after a heart attack
This study looks at how starting an SGLT2 inhibitor (a diabetes medicine) around the time of a heart attack affects heart outcomes and heart muscle changes over time. It may help you and your care team understand whether this timing is beneficial after a PCI procedure.

Eye Injections for Diabetic Vision Loss: Two Treatment Comparison
This study compares two injectable medications (faricimab and biosimilar ranibizumab) used to treat diabetic retinopathy, a serious eye condition that can cause vision loss in people with diabetes. The trial will measure how well each medication works and track specific markers in your eye to understand treatment response.
OsijekAges 18 years+ - NCT07518966Recruiting
Heart Rhythm Treatment Success Tracking Study
This study follows patients getting a newer heart rhythm treatment called pulsed field ablation for atrial fibrillation (an irregular heartbeat). Researchers want to understand which patients do well long-term and which may need additional treatment.
Chengdu, SichuanAges 18 years+ - NCT07516496Recruiting
Understanding Body Chemistry in Vascular Ehlers-Danlos Syndrome
This study looks at how bodies with vascular Ehlers-Danlos syndrome (vEDS) process nutrients and energy differently. By comparing people with vEDS to healthy volunteers, researchers hope to find new ways to manage the condition better.
CambridgeAges 18–85 - NCT07520032Recruiting
Shockwave therapy for arm function after stroke
This trial tests whether a non-invasive shockwave treatment can help improve arm movement and strength in people who had their first stroke within the past 6 months. The goal is to see if this therapy reduces stiffness and helps patients regain better use of their arm.
Ajman, Ajman EmirateAges 18–65 - NCT07524036Recruiting
Nursing education to help stroke patients follow care plans
This study tests whether a special nursing education session helps stroke patients stick to their recovery plan after going home. The goal is to see if personalized teaching improves how well patients take medications and follow doctor's advice.
BayonneAges 18 years+ - NCT07520656Recruiting
Heart Valve Surgery and Sleep Breathing Problems
This study looks at whether fixing heart valve problems with minimally invasive procedures (TAVI or MTEER) can improve sleep-related breathing issues. Researchers will monitor your sleep patterns before and after your scheduled heart valve procedure.
Athens, AtticaAges 18 years+ - NCT07519044RecruitingPhase 4
GM1 drug added to clot removal for acute stroke
This study tests whether adding a medicine called GM1 to emergency clot-removal surgery helps people recover better from sudden strokes caused by blood clots in major brain arteries. GM1 may protect brain cells from damage during and after the stroke.
Beijing, Beijing MunicipalityAges 18–80 - NCT07521800Recruiting
Remote Heart Monitoring After Aortic Valve Replacement
This study tests whether monitoring your heart rhythm at home using a portable ECG device after your aortic valve replacement procedure (TAVI) helps catch problems early. Researchers want to see if remote monitoring is safe and helpful for patients recovering from this procedure.
TurinAges 18 years+ - NCT07521436Recruiting
Understanding Heart Disease Risk Awareness in Men and Women
This study asks people who have had heart or blood vessel problems about their understanding of risk factors and how they view their cardiovascular health. Researchers want to learn whether men and women perceive their heart disease risk differently.
MilanAges 18 years+ - NCT07521384Enrolling by invitation
Real-World Study of Intranasal Cell Therapy for Brain Injuries
This study follows people who receive intranasal stem cell or exosome therapy (tiny packages from special cells) for brain or neurological conditions like stroke, brain injury, or cerebral palsy. Researchers track how well the treatment works by measuring inflammation markers in the blood and monitoring clinical improvements over time.
Monterrey, Nuevo LeónAges 4–80 - NCT07524335RecruitingPhase 3
Aspirin for early coronary artery disease without symptoms
This trial tests whether taking aspirin can help people who have early signs of coronary artery disease (buildup in heart arteries) but have never had a heart attack or stroke. The goal is to see if aspirin prevents future heart problems in these patients.
Montreal, QuebecAges 40 years+ - NCT07519876Recruiting
Blood Clots in the Lungs and Heart Shunts Study
This study looks at whether people with blood clots in their lungs have hidden holes in their hearts that let blood bypass normal circulation. Researchers will use imaging tests to understand this connection and see if it affects how patients do.
