Recruiting studies
- NCT04970888Recruiting
Exercise program to improve thinking and brain blood flow in heart failure
This trial tests whether doing a combined mental (cognitive) and physical exercise program can improve thinking and how well blood flows to the brain in people with chronic heart failure. It may help by strengthening both brain function and physical capacity while your heart condition stays stable.

Study blood flow in the uterus in endometrial cancer
This study looks at how blood flow in the uterus may relate to endometrial cancer. It may help researchers understand the disease better and guide future care.
Banqiao District, New TaipeiAges 20 years+ - NCT05250349Recruiting
Ultrasound brain blood flow and thinking in stable heart failure
This trial studies whether a noninvasive ultrasound test of blood flow in the brain, along with memory and thinking questionnaires, can help explain thinking changes in people with stable heart failure. It may help researchers better understand why some people develop cognitive (thinking) difficulties as heart failure progresses.
Krakow, MPAges 18 years+ - NCT05344274RecruitingPhase 4
Eye blood flow study in people with glaucoma
This study measures how blood flows in the retina and how well the eye regulates that flow. It compares people with early or very early glaucoma to people without glaucoma to see what differences may predict progression.
Baltimore, MarylandAges 18–88 - NCT05423600Recruiting
Telehealth spinal stimulation plus exercise for high-level incomplete SCI
This study tests whether a home, therapist-guided exercise program combined with a spinal stimulation device (with or without limited blood flow) can improve movement and function in people with incomplete tetraplegia. It may help your muscles respond better, but participation depends on safety checks and your ability to do exercises by video.
Richmond, VirginiaAges 18–70 - NCT05573074Recruiting
Light treatment trial for brain blood flow in depression
This study tests whether shining near-infrared light through the head can change brain blood flow and reduce depression symptoms. If you have major depression, you may be offered a non-drug, device-based approach to see how well it helps.
Boston, MassachusettsAges 18–65 - NCT05589974Recruiting
Blood flow study in acute or chronic central serous eye disease
This study measures blood flow in the eye in people with acute or chronic central serous chorioretinopathy (CSC). It uses eye scans and special imaging to better understand what’s happening and whether it may differ between short-term and long-term disease.
StavangerAges 18–70 - NCT05780905RecruitingPhase 4
Semaglutide study for brain blood flow in type 2 diabetes
This trial tests whether semaglutide changes blood flow in the brain and the brain’s “barrier” (how well the brain is protected) in people with type 2 diabetes. It may help researchers understand brain-related effects of diabetes treatment using scans and blood tests.
Seattle, WashingtonAges 40–65 - NCT05884736Recruiting
Checking no blood flow to the brain during certain organ donation
This study looks at whether there is truly no blood flow to the brain during a specific type of organ donation. It aims to confirm safety and timing by using neurological monitoring during the process.
London, OntarioAges 18–75 - NCT06027294Recruiting
Blood flow and muscle function study for stroke survivors
This study looks at how blood flow affects muscle function after a stroke. It may help researchers understand recovery better and find new ways to improve movement.
Milwaukee, WisconsinAges 18–85 - NCT06083948RecruitingPhase 2/Phase 3
Blood pressure medicines and brain blood flow during tumor surgery
This study tests how different blood pressure medicines affect blood flow to the brain and other organs during anesthesia for brain tumor surgery. It aims to find the safest way to keep your brain healthy while you are asleep.
AarhusAges 18–75 - NCT06096532Recruiting
Blood Flow in Fat Tissue and Aging
This study looks at how blood flow in fat tissue changes as we age. Researchers want to see if there are differences between younger adults (18-35) and older adults (65-80) to better understand aging.
Rochester, MinnesotaAges 18–80 - NCT07695090RecruitingPhase 2
Lumacaftor for improved brain blood flow in heart failure
This trial tests if lumacaftor, a medication used in cystic fibrosis, can improve blood flow to the brain in people with stable heart failure. It might help if you have heart failure with reduced pumping function and low brain blood flow.
Toronto, OntarioAges 18 years+ - NCT06411353Recruiting
Blood flow and sounds in new dialysis access
This study looks at blood flow and sounds in new arteriovenous fistulas (AVFs) during dialysis. If you need a new AVF in your forearm, this trial may help doctors understand how to make your fistula work better.
Bergamo, BergamoAges 18–90 - NCT06421987Recruiting
Heart, lung, and brain function in Hodgkin lymphoma survivors
This study looks at how heart, lung, and brain blood flow are affected in adults who survived Hodgkin lymphoma as children. It compares survivors who had certain treatments to healthy volunteers.
Memphis, TennesseeAges 18 years+ - NCT06555042Recruiting
Crohn's disease imaging study with PET-MRI
This study uses a special PET-MRI scan to look at inflammation and blood flow in the small intestine of people with Crohn's disease. It may help doctors better understand disease activity in the gut.
Turku, Southwest FinlandAges 18–70 - NCT06566950Recruiting
Blood flow training for leg muscle health in athletes
This study tests a training method that uses light blood flow restriction to improve leg muscle structure. It is for young athletes (ages 15–35) who play high-level sports like martial arts, basketball, soccer, or futsal at least twice a week.
Denpasar, BaliAges 15–35 - NCT06621914Recruiting
Blood flow restriction training for military with leg injuries
This trial tests a low-weight exercise program using a special cuff on the leg (blood flow restriction) to see if it helps military personnel recover from leg injuries faster. It could be an option if pain is stopping you from doing normal rehab.
Loughborough, LeicestershireAges 18–55 - NCT05163600Recruiting
Exercise with or without blood flow restriction for health
This study compares how your heart and lungs respond to two different types of exercise: one with a special cuff that slightly limits blood flow and one without. It may help if you are healthy or have COPD.
Zurich, Canton of ZurichAges 18–90 - NCT06756646Recruiting
Aerobic exercise and BFRT for COPD patients
This trial tests if adding a special band (BFRT) to walking or biking can help people with COPD breathe better and get stronger. It may be a good option if you have moderate to very severe COPD and haven't been in a rehab program lately.
Tainan, TaiwanAges 30–85 - NCT06791837Recruiting
Brain blood flow and lactate in obesity study
This study looks at how blood flow and lactate (a chemical your body makes) in the brain differ between people with a healthy weight and those with obesity. It may help researchers understand how weight affects brain function.
Columbia, MissouriAges 18–45 - NCT06795230Recruiting
Arm exercise with blood flow cuffs for MS
This study tests a type of arm exercise that uses a blood pressure cuff to limit blood flow, aiming to improve arm function in people with multiple sclerosis. It may help if you have some arm weakness but no recent relapses or blood clotting issues.
Leganés, MadridAges 18 years+ - NCT06826781Recruiting

Common questions
- Are there clinical trials for blood flow?
- Yes. Clin2 currently lists 190 recruiting blood flow studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a blood flow trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a blood flow trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
