Abstract

AIMS: Epicardial adipose tissue (EAT) could contribute to the specific atherosclerosis profile observed in premature coronary artery disease (pCAD) characterized by accelerated plaque burden (calcified and non-calcified), high-risk plaque (HRP) features, and ischaemic recurrence. Our aims were to describe EAT volume and density in pCAD compared with asymptomatic individuals matched on cardiovascular risk factors and to study their relationship with coronary plaque severity extension and vulnerability.

METHODS AND RESULTS: Two hundred and eight patients who underwent coronary computed tomography angiography were analysed. It included 104 consecutive individuals with pCAD (acute or stable obstructive CAD before the age of 45 years) and 104 controls, matched 1:1 on age, sex, and cardiovascular risk factors. EAT volume, volume index (EATi), and density were measured with a semi-automated artificial-intelligence based segmentation method and CAD-RADS V2.0 determined according to guidelines. EAT volume and density were compared across groups, and associations with plaque burden and characteristics were investigated. EAT volume and EATi were significantly higher in patients with pCAD compared with matched controls (71.5 mL/m² [45.7;99.8] vs. 58.5 mL/m² [41.3;81.7] P = 0.002), and EAT density was significantly lower in patients with pCAD compared with matched controls (-82 HU [-87; -79] vs. -82 [-85; -78], P = 0.025). EATi was found to be positively correlated with increasing number…

How strong is the evidence?

Evidence Hub reads this as a case-control, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 104 participants or records.
