Testing acetylcholine during heart artery checks for INOCA/MINOCA
Part of Heart & circulation clinical trials.
This trial studies what acetylcholine testing during a coronary angiogram (CAG) can show in people with INOCA or MINOCA. It may help doctors better understand certain “spasm” or blood-vessel function problems that can cause chest pain or heart-attack-like symptoms without a blocked artery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are age 18 or older.
- You have been diagnosed with INOCA or MINOCA based on your symptoms and heart test results.
- You had an acetylcholine (ACh) provocative test performed inside the heart artery during your coronary angiogram (CAG).
- If your diagnosis is MINOCA, your team does not think the cause is something else like Takotsubo (stress heart), myocarditis, lung clot (pulmonary embolism), or a true blocked/clot-causing coronary issue.
- You can sign an informed consent form to join the study.

This study looks at blood “biomarkers” and platelet function to better understand INOCA (heart-related chest pain despite no major artery blockage). You may be eligible if you have INOCA and are already taking aspirin, and if you haven’t taken certain blood-thinner or platelet-altering medicines recently.
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 why some people have chest pain and heart injury signs, but their heart arteries are not blocked. It tests scans of blood flow and heart tissue to better understand the cause and guide care.
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 why some people have chest pain or other heart symptoms even when their main heart arteries are not blocked. It tests whether inflammation in the small blood vessels of the heart might cause these symptoms, and aims to understand how to better diagnose and treat this condition.
This study looks at people who may have MINOCA (heart attack symptoms with no major artery blockage) or takotsubo syndrome (a temporary stress-related heart condition). The goal is to better understand these causes and how they should be diagnosed and treated.
