Among patients who received statins, in addition to the residual cholesterol risk assessed by low-density lipoprotein cholesterol (LDL-C), residual atherosclerotic and inflammatory risks can be evaluated using low-attenuation plaque and pericoronary adipose tissue (PCAT) attenuation on coronary computed tomography angiography, respectively. When their joint prognostic values were assessed, low-density lipoprotein cholesterol showed no additional prognostic value on low-attenuation plaque burden; among patients with high or low lowattenuation plaque burden (LAPB), low-density lipoprotein cholesterol levels did not significantly affect the outcomes. Conversely, when the fat attenuation index (FAI) was added to low-attenuation plaque burden, the prognostic value improved. Patients with high lowattenuation plaque burden and an increased fat attenuation index showed the worst clinical outcomes.
