Heart attack clues: what makes plaque erode?
NCT ID NCT03479723
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study combined data from over 1,700 patients who had a heart attack or unstable angina and underwent a special imaging test (OCT) of their heart arteries. Researchers aimed to find factors that predict plaque erosion, a common cause of heart attacks. The goal is to better understand why some plaques erode, which could help improve prevention and treatment.
