Various inflammatory cytokines such as interleukin-2 (IL-2), interleukin-6 (IL-6), interleukin-17 (IL-17), tumor necrosis factor-alpha (TNF-α), and interferon-gamma (IFN-γ) have been implicated in CAD, and their concentrations have been found to be associated with increased risks in ACS patients [8–13]. Here, IL2 is linked to coronary artery disorder.
