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+ - NCT06503640Recruiting
Microvascular dysfunction in angina patients
This study tests if chest pain with clear arteries is caused by tiny heart vessel problems. It may help find better treatments for patients whose arteries look normal on angiograms.

Testing heart vessel dysfunction after a heart attack
This trial looks at how to assess small blood-vessel (microvascular) problems in people who had a heart attack but whose main heart arteries are not blocked. It may help doctors better find what’s driving symptoms and choose the right tests and treatments.
Gwangju, GwangjuAges 19 years+ - NCT06376630Recruiting
Esmolol for heart protection during heart attack
This study tests if giving a fast-acting heart medication (esmolol) early through an IV can protect the heart muscle during a heart attack. It may help patients who cannot receive a standard treatment due to certain risks.
MoscowAges 18 years+ - NCT07103317Recruiting
Understanding heart blood flow in chest pain without blockages
This study looks at people who have chest pain but don't have major blockages in their heart arteries. It aims to understand how the tiny blood vessels and artery spasms might be causing symptoms, using special heart tests.
Prague, Česká RepublikaAges 18 years+ - NCT02301663Recruiting
Stress test study of heart blood-flow issues in adults
This study tests a new kind of stress test to understand how small blood-vessel heart problems relate to heart relaxation problems in people with angina (chest pain) but no blocked arteries. It may help doctors learn better ways to diagnose and guide treatment for these conditions.
Los Angeles, CaliforniaAges 18–60 - NCT05841199Recruiting
Study heart blood flow during fast heart rates
This study measures how well blood flows through the heart when the heart rate is increased during a heart procedure. It may help doctors better understand coronary (heart artery) blood flow and how to guide treatment when you need angiography or angioplasty.
LondonAges 18 years+ - 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+ - NCT06579677Recruiting
Watching small blood vessels in the brain over time
This study watches how small blood vessels in the brain change over time. It may help doctors understand brain health as people age.
Beijing, Beijing MunicipalityAges 50–75 - NCT06600178RecruitingPhase 1
Heart medication for women with chest pain and small vessel disease
This trial tests a diabetes medication called SGLT2 inhibitors to see if it can improve blood flow to the heart and reduce chest pain in women who have small vessel heart disease (microvascular dysfunction) but not blocked large arteries. Participants will take the medication and be monitored for symptom relief and heart function improvements.
Charlottesville, VirginiaAges 18 years+ - NCT05960474Recruiting
Study registry for coronary microvascular disease
This trial is a registry, meaning it mainly collects information about people with coronary microvascular disease. It may help researchers better understand the condition and how it affects daily health and treatment needs.
Washington D.C., District of ColumbiaAges 18 years+ - NCT04087655Recruiting
Study obesity and tiny blood-vessel function in women
This study looks at how obesity affects tiny blood vessels and blood flow. It also checks whether a specific training/exercise approach changes these “microvascular” effects in premenopausal women who fit certain metabolic risk criteria.
Tallahassee, FloridaAges 18–45 - NCT06547619RecruitingEarly Phase 1
Blood vessel health after pregnancy with diabetes
This study looks at how blood vessels work in women who had a healthy pregnancy or gestational diabetes. It tests if a substance called ET-1 affects blood vessel function.
Iowa City, IowaAges 18–50 - NCT02180178Recruiting
Heart catheter registry for slow coronary blood flow
This study builds a database of people who are having a coronary angiography (a heart blood-vessel X-ray test). It aims to better understand conditions like slow blood flow in the heart’s small vessels and may help improve how these conditions are diagnosed and treated.
MainzAges Any age - NCT06125392Recruiting
New Definition for Small Heart Vessel Disease
This trial studies a condition where small heart vessels don't work well. It looks at new ways to define this problem using a special test that measures pressure and blood flow in a heart artery.
Mainz, Rhineland-PalatinateAges 18–90 - NCT06076551Recruiting
Sex differences in small blood vessel problems of the heart
This study looks at how small blood vessels in the heart work differently in men and women who have chest pain but no major blockages in their main heart arteries. The goal is to better understand and treat these smaller vessel issues.
SeoulAges 20–80 - NCT05478707RecruitingPhase 2
Treating small blood vessel problems in type 1 diabetes
This study tests whether two different treatment strategies can improve the function of the tiny blood vessels in people with type 1 diabetes. It aims to find a way to prevent or reduce diabetes-related complications.
Orlando, FloridaAges 18–40 - NCT07449325Recruiting
Heart sinus reducer for chest pain from small vessel disease
This trial tests a device placed in a heart vein (the coronary sinus) to improve blood flow and reduce chest pain in people with coronary microvascular dysfunction (small blood vessel disease). It aims to help those who still have symptoms despite taking heart medications.
New Haven, ConnecticutAges 18 years+ - NCT04674449Recruiting
Tests a targeted plan for people with chest pain from heart artery disease
This study aims to match people with angina (chest pain from heart artery problems) to the most helpful treatment plan based on their test results. It’s done around the time doctors are planning an invasive heart scan to look at the coronary arteries.
CorkAges 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 - NCT07222683Recruiting
How kidney transplant affects heart blood vessel health
This study looks at how receiving a kidney transplant changes the health of small blood vessels in the heart. It may help people with advanced kidney disease understand the benefits of transplant on their heart health.

Common questions
- Are there clinical trials for microvascular dysfunction?
- Yes. Clin2 currently lists 58 recruiting microvascular dysfunction 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 microvascular dysfunction 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 microvascular dysfunction 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.
