Device trial for hard-to-treat heart chest pain from small vessels
This trial tests whether a small pressure-reducing device placed in a heart vein (the coronary sinus) can reduce symptoms in people with ongoing chest pain from tiny blood vessel problems. It is for angina that has not improved despite standard heart medicines, and only if special heart tests show reversible reduced blood flow.
Mainz, Rhineland-PalatinateAges 18–85 - NCT06424834RecruitingPhase 2/Phase 3
Targeted medicines for chest pain without blocked arteries
This study tests if specific heart medicines (like beta-blockers or calcium channel blockers) can help people with chest pain that is not caused by blocked arteries. It aims to treat the tiny blood vessels or spasms that may be the real cause of your pain.
Palo Alto, CaliforniaAges 18 years+ - NCT06692751Recruiting
Eye scan for microvascular angina
This study tests if a non-invasive eye scan (OCT-A) can detect changes in tiny blood vessels in the retina of people with chest pain caused by problems with the heart's small arteries (microvascular angina). If it works, it could be a simpler way to diagnose this condition.
DijonAges 18 years+ - NCT06681896Recruiting

Leicester, LeicestershireAges 18 years+ - NCT06092736RecruitingPhase 4
Danshen pill for chest pain with normal arteries
This trial tests if a traditional Chinese medicine pill (compound Danshen dripping pill) can help people who have chest pain on exertion but whose heart arteries appear normal or nearly normal on scans. If you have this type of chest pain and fit the criteria, you may be able to join.
Jinan, ShandongAges 30–75 - NCT07196397Recruiting
Polish Registry of Heart Nerve Procedures
This registry tracks people who have had or plan to have a procedure that changes the nerves controlling heart rate, such as cardioneuroablation. It aims to better understand and treat conditions like inappropriate tachycardia, POTS, and fainting spells.
RzeszówAges 18 years+ - 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+ - NCT06811831RecruitingEarly Phase 1
Mactientan for chest pain from small heart artery problems
This trial tests if mactientan, a blood vessel relaxer, can improve chest pain in people with coronary microvascular angina—where small heart arteries don't work right even though larger ones are clear. It aims to help those with ongoing angina symptoms.
Beijing, Beijing MunicipalityAges 18–75 - 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+ - NCT06898541Enrolling by invitation
A device to treat chest pain from small heart artery disease
This trial tests a device called the Coronary Sinus Reducer for people with chest pain caused by problems in the small arteries of the heart. The device is placed in a vein near the heart to improve blood flow and reduce symptoms.
RotterdamAges 40 years+ - 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 - NCT06243653Recruiting
Heart microvessel function test for heart failure recovery
This trial looks at how tiny blood vessels in the heart affect improvement in heart pumping strength for people with heart failure. It tests whether a special procedure during heart catheterization can predict recovery.
SeoulAges 19 years+ - NCT05178914Recruiting
Testing heart pain treatment guided by blood-flow measurements
This study looks at how to personalize treatment for people with angina (chest pain) by measuring how well blood flows through the heart’s small vessels and the main arteries during a procedure. It may help doctors choose the right approach after your coronary angiography (heart artery imaging).
La TroncheAges 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.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06864234RecruitingPhase 4
Beta-blockers for chest pain without blocked arteries
This trial tests if beta-blocker medication improves blood flow and reduces resistance in the tiny blood vessels of the heart in people who have chest pain but no major blockages in their arteries.
Aalst, FlandersAges 18 years+ - NCT05634031Recruiting
Study of heart vessel dysfunction seen on heart imaging
This study looks at coronary microvascular dysfunction (small blood vessel problems in the heart) using heart imaging. It may help researchers understand causes of chest tightness with activity and shortness of breath when the main heart arteries are not blocked.
New York, New YorkAges 18 years+ - NCT04827498Recruiting
Testing heart blood-flow problems without clogged arteries
This study looks at how well the heart’s blood vessels work in people who have symptoms of reduced blood flow but no major artery blockage. It uses special heart tests with medicines to check how the vessels respond and may help guide better diagnosis and treatment.
MadridAges 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.
