Non-invasive testing for chest pain without blocked arteries
Part of Heart & circulation clinical trials.
This study tests a non-invasive method to evaluate chest pain in people who do not have blocked coronary arteries. It may help patients understand the cause of their symptoms without needing invasive procedures.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 90 years old.
- You had a coronary angiogram in the last year that showed no significant blockages (less than 50% narrowing).
- Your angiogram included a test for artery spasm with a drug called acetylcholine.
- You have not had unstable chest pain or variant angina (a specific type of chest pain at rest with ST elevation on ECG).
- You have not had heart bypass surgery.
- You do not have asthma or intolerance to dipyridamole.

This study compares two ways of testing the small blood vessels in the heart to understand chest pain when no major blockages are found. It may help doctors learn more about why you have chest pain and how to treat it.
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 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 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 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 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.
