Recruiting studies
- NCT06795230Recruiting

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+ - 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 - NCT04149977Recruiting
Blood flow restriction therapy for knee tendon injuries
This study tests whether blood flow restriction therapy can help healing and recovery after certain knee extensor injuries (like patella or quadriceps tendon rupture). You must be able to take part in the usual physical therapy plan, too.
New York, New YorkAges 18–65 - NCT06254794Recruiting
Blood flow restriction rehab after Achilles tendon repair
This study tests whether adding blood flow restriction (BFR) to standard physical therapy helps people recover better after Achilles tendon repair surgery. You may be a good fit if you had a PARS or open repair and plan to rehab at a Methodist Hospital.
Houston, TexasAges 18 years+ - 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 - NCT05954832Recruiting
Monitoring heart function and blood flow during general anesthesia
This study checks how heart function and blood flow change in adults while they receive general anesthesia for surgery. It may help doctors better understand what happens to the heart during anesthesia and adjust care for safety.
New York, New YorkAges 18 years+ - 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 - 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 - 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.
Montreal, QuebecAges 50 years+ - NCT05726058Recruiting
Imaging eye blood flow to assess glaucoma
This study uses special imaging to look at blood flow in the eye to help assess or better understand glaucoma. You may be eligible if you’re an adult with eye exams that fit the study’s specific eye-health and imaging requirements.
Baltimore, MarylandAges 18–88 - 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 - 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 - 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 - NCT05115890Recruiting
Testing blood-flow control in heart failure with preserved pumping
This study looks at how well blood flow is regulated in people with HFpEF, a type of heart failure where the heart squeezes normally but doesn’t fill properly. It may help researchers understand the cause of symptoms and how to improve treatment strategies.
Salt Lake City, UtahAges 18 years+ - NCT04401982RecruitingPhase 4
Testing eye drops for blood flow in high eye pressure and glaucoma
This study tests whether three different eye drop treatments (netarsudil, latanoprost, or both together) can improve blood flow to the white part of the eye and the retina. It may help people with high eye pressure or who are glaucoma suspects better understand how these treatments work.
Baltimore, MarylandAges 18 years+ - NCT04442451Recruiting
Study how fatigue happens in prediabetes and type 2 diabetes
This study looks at why people with prediabetes or type 2 diabetes may feel unusually tired during activities. You may be asked to do exercise testing and answer questions to help researchers understand the body changes behind fatigue.

Common questions
- Are there clinical trials for blood flow?
- Yes. Clin2 currently lists 184 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.
