IL6 and endothelial dysfunction: Key immunological markers, including interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), monocyte chemoattractant protein-1 (MCP-1), and adhesion molecules (ICAM-1, VCAM-1), are implicated in endothelial dysfunction, myocardial apoptosis, and ventricular remodeling.
