Heart artery function test for chest pain
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have had chest pain or tightness that feels like angina.
- Your main heart arteries have been checked and have no major blockages (less than 50% narrowing).
- You are at least 18 years old.
- You would need to sign a consent form agreeing to the study.

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 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 helps women with chest pain or heart symptoms who have normal-looking coronary arteries (the blood vessels that feed the heart). Researchers will perform specialized heart tests to understand why you have symptoms, then tailor treatment based on your specific condition.
This study is testing a new way to measure blood flow in the heart's small arteries (called caIMR) to help doctors decide on the best treatment for people with certain types of chest pain or suspected reduced blood flow. It is for patients who do not have major blockages but might still have issues in the small vessels or along a long segment of the artery.
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 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.
