Epicardial Adipose Tissue Volume Assessment in the General Population and CAD-RADS 2.0 Score Correlation Using Dual Source Cardiac CT
<b>Objectives:</b> Our study aims to investigate the correlation between epicardial adipose tissue (EAT) volume assessed with non-contrast cardiac CT (NCCCT) and sex, age, coronary artery disease reporting and data system (CAD-RADS 2.0) categories, and coronary artery calcification (CAC)...

| Summary: | <b>Objectives:</b> Our study aims to investigate the correlation between epicardial adipose tissue (EAT) volume assessed with non-contrast cardiac CT (NCCCT) and sex, age, coronary artery disease reporting and data system (CAD-RADS 2.0) categories, and coronary artery calcification (CAC) extent. The secondary aim is to establish the average values of EAT in a population considered healthy for coronary artery disease (CAD). <b>Materials and Methods:</b> We retrospectively analyzed patients who underwent coronary computed tomography angiography (CCTA) at our institution from January 2023 to August 2024. The CAD-RADS 2.0 scoring system was applied to assess the extent of CAD; CAC extent was quantified according to the Agatston score. EAT was segmented semi-automatically in NCCCT images, and its volume was subsequently measured. Correlation analyses between EAT volume, sex, patient age, CAC, and CAD-RADS categories were conducted. <b>Results:</b> A total of 489 consecutive patients met the inclusion criteria (63.96 ± 12.18 years; 214 females). The mean EAT volume ± SD in those categorized as CAD-RADS 0 (57.25 ± 15.45 years, 120 patients) was 117.43 ± 50.30 cm<sup>3</sup>: values were higher in men (121.07 ± 53.31 cm<sup>3</sup>) than in women (114.54 ± 47.98 cm<sup>3</sup>). EAT volumes positively correlated with age, male sex, CAD severity, and CAC scores. <b>Conclusions:</b> According to our results, males in all CAD-RADS categories have a greater amount of EAT than females. A positive correlation between the volume of EAT and factors such as age (<i>p</i> = 0.003), CAD-RADS categories (<i>p</i>: 0.004), and coronary calcium score (<i>p</i> = 0.0001) with a strong influence exerted by sex was demonstrated. Our results reinforce the observation that higher EAT volumes are associated with a more severe coronary artery disease. |
