Tel AvivAges 20–75 - NCT07074847Enrolling by invitation
Heart artery microcirculation and metabolism study
This trial looks at the tiny blood vessels in the heart and how they work in people who have no major blockages. It may help understand chest pain that isn't caused by large artery narrowing.
Xi'an, ShaanxiAges 18–80 - NCT06799832Recruiting
Guiding fluid management during major abdominal surgery using a new index
This study tests whether a new tool, the urethral perfusion index, can help doctors better manage fluids during and after major abdominal surgery. It uses standard catheters already in place, so there's no extra device needed.
HamburgAges 45 years+ - NCT05984537RecruitingPhase 4
Bivalirudin during angioplasty for high-risk heart plaques
This study tests whether a blood thinner called bivalirudin, given during a procedure to open blocked heart arteries (PCI), helps blood flow better in the tiny vessels of the heart afterward. It is for people with a recent unstable heart condition and a high-risk plaque seen on a CT scan.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05682924Recruiting
Study blood vessel function in CML patients on bosutinib
This study looks at how well your blood vessels work (“vasoregulation”) in people with chronic myeloid leukemia (CML) while taking bosutinib. The goal is to understand vascular changes and how they relate to treatment in CML.
MoscowAges 40–60 - NCT06193980Recruiting
ICU recovery exercise test study
This trial looks at how well your heart and lungs work together after a long stay in the ICU on a breathing machine. It uses a simple exercise test to check your recovery after leaving the hospital.
Winnipeg, ManitobaAges 18 years+ - NCT06266065Recruiting
Heart vein device for chest pain not helped by medication
This trial tests a small device placed in a vein near the heart to improve blood flow and reduce chest pain in people who cannot have bypass surgery or stents. The device aims to increase the heart's oxygen supply and relieve symptoms.
ZagrebAges 18–90 - NCT06341062Recruiting
Ultrasound test for kidney injury in the ICU
This study tests whether a special ultrasound with a contrast dye can help doctors better assess acute kidney injury (a sudden drop in kidney function) in patients in the intensive care unit. If you or your loved one has been diagnosed with acute kidney injury within 24 hours of ICU admission, this imaging test may help guide care.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06356727Recruiting
Blood vessel health test for heart recovery
This study checks if tiny blood vessel problems in the heart affect how well the heart muscle recovers after being weak. It uses special imaging during a routine heart catheterization to look at these small vessels.
FerraraAges 18–85 - NCT06393478Recruiting
Southeastern Europe Microcirculation Registry
This study is collecting information about how well the tiny blood vessels in the heart work in people with chest pain. It helps doctors learn more about microcirculation problems and may lead to better treatments.
RijekaAges 18 years+ - NCT06597851Recruiting
Insulin resistance and heart artery health: a study for chest pain patients
This study looks at how insulin resistance affects tiny heart arteries in people who have chest pain and signs of heart stress on tests, but do not have major blockages in their heart arteries. It aims to understand why some people have heart symptoms even when their main arteries appear clear.
Verona, VRAges 18 years+ - NCT06669962Recruiting
Studying heart function in Takotsubo syndrome

Common questions
- Are there clinical trials for microcirculation?
- Yes. Clin2 currently lists 32 recruiting microcirculation 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 microcirculation 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 microcirculation 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.
