Testing small heart blood vessels in patients with chest pain
Part of Heart & circulation clinical trials.
This trial is testing a new way to diagnose problems in the small blood vessels of the heart that can cause chest pain even when the main arteries look clear. The test uses a special technique to measure how well these small vessels work, which could help find the cause of your symptoms.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have symptoms of angina (chest pain or discomfort).
- You are 18 years or older.
- You have had an angiogram showing your heart arteries are clear or have only mild narrowing (less than 50%).
- You are not pregnant.
- You have not had heart bypass surgery (CABG) before.
- You do not have moderate to severe heart valve disease.

This trial tests a special wireless pressure catheter to see how well the tiny blood vessels in the heart are working. It may help people who have chest pain but don't have major blockages in their main heart arteries.
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.
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 looks at the tiny blood vessels in your heart (the microcirculation) that can cause chest pain even when the main arteries are open. It aims to better understand and treat this type of chest pain, called chronic coronary syndrome.
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.
This trial studies people who have chest pain (angina) due to problems with the heart’s small arteries, not a big blockage. It aims to test whether treatment approaches can help these patients by better understanding the cause of their heart-related symptoms.
