Heart attack without blocked arteries: Italian study

This study uses a special eye scan (OCTA) to look at tiny blood vessels in the eye and see if they can help predict outcomes for people who had a heart attack without blocked arteries (MINOCA). It compares these patients to others with typical heart attacks and healthy people.

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 tests whether an implantable heart rhythm monitor can detect atrial fibrillation (an irregular heartbeat) in people who had a type of heart attack with non-obstructed arteries. The goal is to find a possible reason for the event so doctors can treat it appropriately.

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 research study looks at why people with chest pain but clear heart arteries have low fitness. It tests whether a home-based interval training program (short bursts of hard exercise) can improve fitness and quality of life.

This trial tests a new imaging technique called μFR to help doctors decide which blockages in your heart arteries need treatment after you've had a heart attack. It may help identify which blockages are most dangerous and need fixing soon versus those that can wait.
