Balance exercises for stroke-related tiredness
This study tests if specific balance exercises can help reduce tiredness after a stroke. If you had a stroke at least 6 months ago and can walk a little, you may be able to join.
AnkaraAges 18–65 - NCT06956560Recruiting
Heart Scar Imaging Study for Heart Attack and Failure Patients
This study uses a special imaging agent to see a protein called PDGFRß in the heart, which may help detect scarring (fibrosis) after a heart attack or in heart failure. It aims to improve how we understand and treat heart muscle damage.
UppsalaAges 40–70 - NCT06957366Recruiting
Managing Blood Thinners Before High-Risk Surgery
This study looks at how to safely manage your blood thinner (DOAC) around the time of a planned, high-bleed-risk surgery or procedure involving a spinal needle. The goal is to find the best way to stop and restart your medication to prevent bleeding and clotting problems.
Hartford, ConnecticutAges 18 years+ - NCT06958029Recruiting
Heart rhythm after heart surgery study
This study looks at how often a fast, irregular heartbeat (atrial fibrillation) happens after heart valve or bypass surgery. Knowing this could help doctors take better care of patients after these procedures.
Khon KaenAges 18 years+ - NCT06958588RecruitingPhase 4
PEMF therapy vs. leg compression for blood clot prevention in ICU
This trial is testing two different ways to prevent dangerous blood clots in ICU patients who cannot take blood-thinning medication. It compares a pulsed electromagnetic field device (PEMF) to a standard leg compression device. Both treatments are non-invasive and used without medication.
Belo Horizonte, BHAges Any age - NCT06959199Recruiting
Treating stroke beyond 24 hours with artery-opening procedure
This study tests whether opening a blocked large artery in the brain up to 5 days (or even 7 days if symptoms are worsening) after a stroke can improve outcomes. It uses a catheter-based treatment (endovascular therapy) for people who have not responded to standard care and have limited brain damage so far.
Hefei, AnhuiAges 18 years+ - NCT06959628Recruiting
Study of a new shunt system for carotid artery blockage treatment
This trial tests a special shunt system to protect your brain during carotid artery stenting. It may help people with severe blockages in the neck artery that supplies blood to the brain.
BeijingAges 18 years+ - NCT06960252Recruiting
Cycle length mapping for long-term atrial fibrillation
This study tests a new mapping technique to find chaotic electrical signals in the heart during persistent atrial fibrillation. It may help doctors better target treatment for people whose atrial fibrillation does not stop with medication.
Taipei, Outside USAges 20 years+ - NCT06960902Recruiting
Study of Heart Artery Plaque in Familial Hypercholesterolemia
This study uses a heart CT scan to look for plaque buildup in the arteries of people with familial hypercholesterolemia (a genetic high-cholesterol condition). It aims to understand why some people with FH develop heart disease while others don't.
DijonAges 40 years+ - NCT06960993Recruiting
Mosaic trial for stem cell transplant patients
This trial tests a website designed to help patients learn about stem cell transplants for blood cancers. It aims to support you during your transplant journey.
Washington D.C., District of ColumbiaAges 18 years+ - NCT06961669Recruiting
CD19 CAR-T cells for B-cell cancers and multiple myeloma
This trial tests a personalized treatment where your own immune cells are modified to target and kill cancer cells that have a protein called CD19. It is for patients with certain types of B-cell lymphoma, B-cell acute leukemia, or multiple myeloma that has come back or not responded to previous treatment.
HefeiAges 3 years+ - NCT06961929Recruiting
Heat and Heart Failure Study
This study looks at how heat affects the body in people with stable heart failure compared to healthy volunteers. It may help researchers understand how to better manage heart failure in daily life.
Dallas, TexasAges 45 years+ - NCT06962397Recruiting
Using touch to improve recovery after stroke
This study tests if using a special device to feel different textures can help improve hand and arm recovery in people who have had a stroke.
MoscowAges 18–80 - NCT06962371Recruiting
A study testing a new device during TAVR heart valve replacement
This trial is testing a new device called POINT-GUARD that is used during TAVR (a procedure to replace a heart valve). It aims to see if the device can safely catch any debris or particles that might travel to the brain during the procedure.
Clayton, VictoriaAges 18 years+ - NCT06962488Recruiting
Personalized blood pressure care using genetic risk
This study uses your genetic information (a polygenic risk score) to guide personalized blood pressure management. It aims to help people with high blood pressure and overall poor heart health improve their levels through tailored advice.
Birmingham, AlabamaAges 18–55 - NCT06963489Recruiting
Stroke biobank study for large vessel blockage
This study collects blood and tissue samples from people who had a stroke caused by a blockage in a large artery in the brain. The goal is to learn more about the condition by studying these samples over time.
Wuhu, AnhuiAges Any age - NCT06963736Recruiting
Reducing health risks from too much evening screen time
This study tests simple strategies to help people who spend a lot of time on screens at night and eat after 8pm. It aims to reduce health risks like high blood pressure, belly fat, and blood sugar issues.

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+ - NCT06965023Recruiting
Microplastics in heart attack patients
This trial looks for tiny plastic particles (microplastics and nanoplastics) in blood clots from people having a severe heart attack (STEMI) who need a procedure to open a blocked artery. It may help us understand if these particles are linked to heart attacks.
