Testing heart blood-flow problems without clogged arteries
Part of Genetic & congenital, Heart & circulation, Pain clinical trials.
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.
Summary written for real people, not researchers, by Clin2.

- Be 18 years or older

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.
This study examines how a special measurement technique works when blood vessels are dilated during a heart imaging procedure. It may help doctors better assess whether narrowing in your heart arteries needs treatment.
This study is looking at people who have chest pain or shortness of breath but whose heart arteries look fairly open on an angiogram. It aims to understand why they have symptoms and how to improve care. You may qualify if you're having a coronary angiogram and it shows no major blockages.
This study tests a new way to measure small blood vessel function in people with chest pain but clear main arteries. It aims to find hidden causes of discomfort so doctors can choose the right treatment.
This study looks at people who are being checked for possible heart artery–related chest or similar discomfort, but without major artery blockage (non-obstructive arteries). It aims to help doctors understand what might be causing symptoms and guide safer testing.
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.
