Higher epicardial adipose tissue volumes positively correlated with age (p=0.003), CAD-RADS categories (p=0.004), and coronary calcium score (p=0.0001).

Higher epicardial adipose tissue volumes assessed by non-contrast cardiac CT correlate with older age, male sex, higher coronary calcium scores, and more severe CAD-RADS categories.
p-value: p=0.004
Objectives: 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). Materials and Methods: 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. Results: 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 cm3: values were higher in men (121.07 ± 53.31 cm3) than in women (114.54 ± 47.98 cm3). EAT volumes positively correlated with age, male sex, CAD severity, and CAC scores. Conclusions: 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 (p = 0.003), CAD-RADS categories (p: 0.004), and coronary calcium score (p = 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.
Dell’Aversana et al. (Mon,) conducted a cross-sectional in Coronary artery disease (n=489). Epicardial adipose tissue (EAT) volume was evaluated on Correlation between EAT volume and CAD-RADS categories (p=0.004). Higher epicardial adipose tissue volumes positively correlated with age (p=0.003), CAD-RADS categories (p=0.004), and coronary calcium score (p=0.0001).
