Tests tiny heart blood-flow changes after type 2 heart attacks
Part of Heart & circulation clinical trials.
This study looks at how well the smallest heart blood vessels work after a type 2 myocardial infarction (a heart injury related to oxygen supply/demand problems, not a blocked artery). It may help researchers better understand what causes symptoms and guide future treatments.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You can understand the study and sign informed consent
- Your heart’s pumping function is mostly normal, with at most mild valve disease
- If you’re a control person: you have atypical chest pain and are being tested for coronary microvascular dysfunction
- If you had a type 2 heart attack (T2MI): your diagnosis must match the standard definition (troponin change plus symptoms or ischemia signs)
- You must be able to take heparin during heart testing (no allergy or other reasons you can’t)
- Your heart testing plan is compatible with medicines used in the study (acetylcholine, adenosine, and nitroglycerin)

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 how to personalize treatment for people with angina (chest pain) by measuring how well blood flows through the heart’s small vessels and the main arteries during a procedure. It may help doctors choose the right approach after your coronary angiography (heart artery imaging).
This study tests a new way to diagnose small blood vessel disease in the heart using an MRI scan during a stress test. It is for people who are already participating in a larger heart imaging study and are scheduled for a catheter procedure.
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 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 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.
