The current minireview aims to assess the implications of epicardial fat secretory function in the development of coronary artery disease. The epicardial adipose tissue (EAT) is a visceral fat depot that has been described as a cardiovascular risk factor. In addition to its mechanical protection role and physiological secretory function, it seems that various secretion products of the epicardial fat are responsible for metabolic disturbances at the level of the cardiac muscle when in association with pre-existing pathological conditions, such as metabolic syndrome. There is a pathological reduction in sarcomere shortening, abnormal cytosolic Ca²⁺ fluxes, reduced expression of sarcoplasmic endoplasmic reticulum ATPase 2a and decreased insulin-mediated Akt-Ser473-phosphorylation in association with abnormal levels of epicardial fat tissue. Activin A, angiopoietin-2, and CD14-positive monocytes selectively accumulate in the diseased myocardium, resulting in reduced cardiomyocyte contractile function. At the same time, it is believed that these alterations in secretory products directly decrease the myocyte function via molecular changes, thus contributing to the development of coronary disease when certain comorbidities are associated.

Inflammation plays a pivotal role in the pathogenesis of acute coronary syndromes (ACS), contributing to plaque instability, thrombosis, and myocardial injury. This review aims to comprehensively examine the inflammatory mechanisms underlying ACS and evaluate current and emerging anti-inflammatory therapeutic strategies. We conducted a comprehensive literature review examining the role of inflammatory pathways in ACS pathophysiology, including innate and adaptive immune responses, key inflammatory mediators, and cellular mechanisms. We analyzed current evidence for anti-inflammatory therapies and their clinical outcomes in ACS management. Inflammatory processes in ACS involve complex interactions between innate immune cells (neutrophils, macrophages, monocytes) and adaptive immune cells (T lymphocytes, B cells). Key mechanisms include neutrophil extracellular trap (NET) formation, macrophage polarization, T cell subset imbalances (Th1/Th17 predominance with regulatory T cell dysfunction), and complement activation. Inflammatory biomarkers such as C-reactive protein, interleukin-6, and NET-specific markers demonstrate prognostic value. Anti-inflammatory therapies including colchicine, canakinumab (IL-1β inhibition), and methotrexate have shown cardiovascular benefits in clinical trials. Emerging targets include NET inhibition, T cell modulation, and precision inflammatory profiling approaches. Inflammation represents a critical therapeutic target in ACS beyond traditional risk factor modification. While colchicine and IL-1β inhibition have demonstrated clinical efficacy, future strategies should focus on precision medicine approaches targeting specific inflammatory pathways based on individual patient profiles. Integration of anti-inflammatory therapy with lipid management and antithrombotic strategies offers promise for improving ACS outcomes through comprehensive targeting of the multifactorial pathophysiology underlying coronary artery disease.
