Two representative images of PCAT attenuation differences between patients with and without MACE measured by CCTA. (A) A 57-year-old patient (male) with MACE, the PCAT attenuation was − 70HU. (B) A 42-year-old patient (male) without MACE, the PCAT attenuation was − 84HU. CCTA = coronary computed tomography angiography, HU = hounsfield unit, MACE = major adverse cardiovascular event, PCAT = peri-coronary adipose tissue.
