Society of Cardiovascular Computed Tomography / North American Society of Cardiovascular Imaging – Expert Consensus Document on Coronary CT Imaging of Atherosclerotic Plaque

Relationship of age, atherosclerosis and angiographic stenosis using artificial intelligence

“…This includes the presence of high-risk plaque features such as NCP, LD-NCP and PR that qualitatively portend, by SCCT expert consensus, a future risk of cardiovascular events. 21 Importantly, AI identified a higher PAV of LD-NCP in younger individuals with non-obstructive atherosclerosis, a plaque type identified as highest risk by cardiac CT. 22 These data affirm prior findings that younger patients have high volumes of non-calcified atherosclerosis with a higher degree of LD-NCP, while older patients develop a higher degree of calcified plaque in both non-obstructive and obstructive lesions. 22 Lowenstern et al ’s subanalysis of the PROMISE (Prospective Multicenter Imaging Study for Evaluation of Chest Pain) study also supports the finding that older patients have more calcified plaque.…”

Association between higher pericoronary adipose tissue attenuation measured by coronary computed tomography angiography and nonalcoholic fatty liver disease

“…who were blinded to clinical and CT data. Plaque characteristics were defined in accordance with the Society of Cardiovascular CT. [ 13 ] Significant coronary artery stenosis was defined by a cross-sectional narrowing of >50%. The vascular remodeling index was calculated by dividing the cross-sectional lesion vessel area by the proximal reference vessel area.…”

Epicardial Adipose Tissue Volume As a Marker of Subclinical Coronary Atherosclerosis in Rheumatoid Arthritis

“…Lesions yielding >50% luminal stenosis were considered obstructive. Both multivessel disease and obstructive disease portend high cardiovascular event risk (35). Plaque composition was identified as noncalcified, mixed, or calcified, as described in a previous study (36).…”
