Epicardial Adipose Tissue from Computed Tomography: a Missing Link in Premature Coronary Artery Disease?

Purpose: 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 features (HRP) and ischemic recurrence. Our aims were to describe EAT volume and density in pCAD compared to asymptomatic individuals matched on CV risk factors and to study their relationship with coronary plaque severity extension and vulnerability.
Materials And Methods: 208 patients who underwent coronary computed tomography angiography (CCTA) were analyzed.

FoxP3 T-regulatory (Treg) lymphocytes and cytokine production by cells from the stromal vascular fraction (SVF) of epicardial (EAT) and thymus (TAT) adipose tissue of 42 patients with chronic coronary heart disease (CHD) were studied. In the SVF of TAT in patients with Gensini Score (GS)≥74 (the most severe atherosclerosis), the production of IL-1β, TNF, IL-4, and IFNγ was higher, while FoxP3 translocation into the nucleus was lower than in patients with GS<74. The GS index directly correlated with the production of IL-4, IL-1β, and TNF by cells of the SVF of TAT, and inversely - with the production of TNF, IL-17, and IL-10 by cells of the SVF of EAT.

Purpose: Hemorrhagic transformation (HT) is a severe complication in patients with acute ischemic stroke (AIS) undergoing intravenous thrombolysis therapy (IVT). Epicardial adipose tissue (EAT) contributes to the development of AIS and the disruption of the blood-brain barrier. This study aims to investigate the relationship between EAT and the risk of HT, as well as functional outcomes, in AIS patients treated with IVT.

Article Synopsis
- Epicardial adipose tissue (EAT) is linked to atrial fibrillation (AF) and atrial fibrosis, but many AF patients show no signs of left atrial (LA) fibrosis. This study compared EAT levels in AF patients without LA fibrosis to matched controls without AF.
- AF patients without LA fibrosis had significantly higher total and regional volumes of EAT compared to controls, indicating that EAT may play a role in AF development even when LA fibrosis is absent.
- The study found no differences in EAT volumes between AF patients with and without LA fibrosis and no significant link between EAT volume and AF recurrence after catheter ablation.
Predictive value of epicardial adipose tissue volume for early detection of left ventricular dysfunction in patients suspected of coronary artery disease.

Aim: To investigate the relationship between epicardial adipose tissue (EAT) and myocardial strain and the severity of coronary artery disease (CAD), and to evaluate the predictive value of EAT parameters in early left ventricular (LV) diastolic dysfunction.
Materials And Methods: One hundred seventy patients with suspected CAD who underwent both coronary computed tomography angiography and echocardiography were enrolled in 2020. LV global strains were calculated using commercial software.
