Objectives

Narrative objectives1

In a previous study that investigated the presence of coronary high intensity plaque (HIP) detected by non-contrast T1-weighted imaging (T1WI), the signal intensity of coronary plaque-to-cardiac muscle ratio (PMR) >1.0 was associated with coronary events. This study aimed to investigate the histopathological characteristics of HIPs in the coronary artery.

First, the lesion is evaluated by cardiac MRI, and the lesion is divided into two groups, HIP and non-HIP group. Within 30 days after cardiac MRI, the lesion is treated with catheterization using directional coronary athrectomy, and the plaques are collected. The collected plaques are fixed in formalin, and deliver to the Department of Pathology, Hyogo College of Medicine with anonymized. All plaques are pathologicaly evaluated without patient'data. The obtained pathological data is analyzed at the Himeji Cardiovascular Center.
