Background: Type 2 diabetes (T2D patients) have a 74% increased risk of heart failure (HF), but traditional HF biomarkers lack sensitivity in early disease detection. Increased epicardial adipose tissue volume (EATv) is associated with cardiovascular risk in T2D, and novel biomarkers such as growth differentiation factor 15 (GDF15), Galectin-3, and soluble suppression of tumorigenicity 2 (sST2) are inflammation biomarkers linked to HF. Methods: We investigated associations between EATv, inflammation biomarkers, and the effect of metabolic control in 14 healthy controls (HCs) and 36 newly diagnosed T2D patients both before (poor glycemic control, PGC) and after 12 months of glycemic optimization (good glycemic control, GGC). EATv indexed to body surface area (iEATv) was quantified by multidetector computed tomography, and biomarker levels were measured by immunoassays. Results: PGC patients had higher iEATv (59.53 ± 21.67 vs. 36.84 ± 16.57 cm3/m2, p = 0.0017) and elevated GDF15, Galectin-3, and sST2 levels (all p < 0.05) than HC subjects. The glycemic optimization reduced iEATv (p = 0.0232) and sST2 (p = 0.048), while GDF15 and Galectin-3 remained unchanged. Multivariable analysis confirmed independent associations between iEATv, GDF15 (β = 0.27, p = 0.027) and sST2 (β = 0.29, p = 0.02). Conclusions: These results support the link between systemic inflammation, EAT expansion, and cardiac dysfunction, and they point to the role of epicardial fat in early HF risk of T2D patients.
