Cord blood S100B protein in growth-restricted newborns
This study measures a protein called S100B in umbilical cord blood to learn more about brain development in newborns with fetal growth restriction (FGR), a condition where a baby is smaller than expected. Understanding this protein could help doctors identify babies who may need extra support after birth.

Cord Blood Protein in Anemia Transfusion Study
This study measures a protein (S100B) in cord blood from babies who had or did not need a blood transfusion in the womb for hemolytic disease. It looks for possible markers of brain health.
WarsawAges 18 years+ - NCT07383220Recruiting
Electrical stimulation and exercise for resistant high blood pressure
This trial tests if adding electrical stimulation to exercise can improve blood flow in people with resistant high blood pressure. It may help those whose blood pressure stays high despite taking multiple medications.
Port Said, Port Said GovernorateAges 50–60 - NCT07370103Recruiting
Predicting low blood pressure in liver disease patients after anesthesia
This study uses an ultrasound to measure blood flow in the neck's main artery to see if it can predict a dangerous drop in blood pressure after you are put to sleep for surgery. It is for adult patients with chronic liver disease who are having planned surgery.
CairoAges 18 years+ - NCT07488793Recruiting
Remote conditioning for spinal cord injury
This study tests a non-invasive method called remote ischemic conditioning, which involves brief cycles of inflation and deflation of a blood pressure cuff on the arm. It may help improve health outcomes for people with spinal cord injury who are not currently able to exercise.
St Louis, MissouriAges 18 years+ - NCT06629077RecruitingPhase 2
Brain blood vessel response to blood flow changes
This study looks at how blood vessels in the brain react when blood flow changes. It may help researchers understand how the brain adapts with age.
Madison, WisconsinAges 55–69 - NCT06629090RecruitingPhase 2
Brain blood vessel responses to blood flow changes: younger adults
This study looks at how the brain's blood vessels respond to changes in blood flow in healthy younger adults. It helps researchers understand normal brain aging.
Madison, WisconsinAges 20–40 - NCT05400174Recruiting
How blood pressure changes affect thinking and brain flow in Parkinson’s
This study measures how your blood pressure affects thinking skills and how blood flows in the brain in people with Parkinson’s. It may help researchers understand what blood-pressure changes could mean for cognition in Parkinson’s.
San Diego, CaliforniaAges 50 years+ - NCT07019519Recruiting
Gut hormones and blood flow in POTS
This study looks at how gut hormones control blood flow after eating in people with POTS. It may help explain symptoms like dizziness and rapid heartbeat after meals.
CopenhagenAges 18–50 - NCT03773159Recruiting
Testing a blood clot test using whole blood flow
This trial tests a new lab device that measures how well your body forms primary blood clots while blood is kept in flowing conditions. It may help doctors better assess bleeding or clotting tendencies and guide future care.
BesançonAges 18 years+ - NCT05679739Recruiting
Caring for brain after cardiac arrest
This study tests a treatment approach aimed at protecting the brain and supporting better blood flow to the brain after a cardiac arrest. It may help some people who are in a coma right after the event recover more safely or with less brain injury.
SingaporeAges 21–79 - NCT06969547Recruiting
Heart muscle coordination and microvessel function SPECT study
This study uses a special heart scan (SPECT) to look at how well the heart muscle is squeezing and how well the tiny blood vessels in the heart are working. It may help doctors understand why some people have chest pain even when their main arteries are not blocked.
TomskAges 18–75 - NCT06878482RecruitingPhase 4
Botulinum toxin injection for severe leg artery disease
This trial tests whether a single injection of botulinum toxin (a muscle-relaxing substance) into the leg can improve blood flow and help heal wounds in people with severe blocked leg arteries who cannot have standard procedures like angioplasty.
Yongin-si, Gyeonggi-doAges 20 years+ - NCT07754162Recruiting
Ultrasound measurement of belly muscle after blood flow training
This trial uses ultrasound to check if different testers get the same measurement of belly muscle thickness after a special workout that limits blood flow. It's for healthy, active people to improve measurement reliability.
IslamabadAges 18–40 - NCT06520982RecruitingEarly Phase 1
Early brain and blood vessel changes in aging women
This study looks at how blood vessels in the brain change as women age. It may help understand why some women have higher risk for certain health problems later in life.
Columbia, MissouriAges 18–70 - NCT05012982Recruiting
Blood-flow restriction training after ACL surgery
This study looks at whether a special exercise method called blood-flow restriction (BFR) training changes blood and metabolism-related responses after ACL reconstruction surgery. It may help people understand who could safely benefit from BFR during recovery.
Milford, ConnecticutAges 18–60 - NCT04822649Recruiting
Assessing exercise capacity in people with heart microvascular problems
This study looks at how well you can exercise and how your body composition relates to tiny blood-vessel problems in the heart. It may help doctors better understand symptoms and function in people who don’t have major blockages in the large heart arteries.
SeoulAges 20–80 - NCT03821467Recruiting
Eye scan study to test a new imaging method in healthy adults
This study checks whether a specific eye-scanning technology gives consistent, repeatable results. It enrolls healthy adults to see if the test works reliably before being used more broadly.
Vienna, State of ViennaAges 18–35 - NCT05303363Recruiting
Checking brain blood flow during a breathing heart-lung machine
This study monitors how much blood is reaching the brain in adults who need a specific type of life-support called VV-ECMO. The goal is to better understand brain blood flow and how monitoring may help manage care during ECMO.
Amsterdam-ZuidoostAges 18–100 - NCT04391465Recruiting
Blood flow and heart rate during a heart procedure study
This study looks at how changes in blood flow in the brain relate to heart rate during a specific heart rhythm procedure. It may help doctors better understand how the body’s brain and heart responses connect during temporary pacing.

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.
