Testing heart vessel dysfunction after a heart attack
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be age 19 or older
- Have had an acute heart attack recently (it’s based on blood test changes plus symptoms/signs of reduced blood flow to the heart)
- Your coronary artery evaluation shows non-obstructive disease (less than 50% narrowing or an FFR above 0.80)
- You must not have a past history of coronary artery disease
- You need to be able and willing to have heart testing soon after arriving (invasive and non-invasive physiologic assessments)
- Be able to give consent (and not be pregnant or breastfeeding)

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.
This study looks at how small blood vessels in the heart work in people who have had a type 2 heart attack. It aims to understand why this happens and how to better treat it.
This study tests a way to measure tiny blood vessels in the heart after a major heart attack (STEMI) using a special catheter with salt water. The goal is to see if this test helps doctors understand how well your heart is healing.
This study looks at why some people with angina (chest pain) have problems with the tiny blood vessels in the heart, even when the large arteries are not blocked. It aims to understand the cause, which may help improve future treatments.
This study checks if tiny blood vessel problems in the heart affect how well the heart muscle recovers after being weak. It uses special imaging during a routine heart catheterization to look at these small vessels.
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.
