However, there were no significant differences in plasma TNF-α (9.61 (7.09–13.71) pg/ml vs. 8.70 (6.53–12.79) pg/ml), IL-6 (1.82 (1.11–3.16) pg/ml vs. 1.32 (0.74–2.41) pg/ml) and hs-CRP (1.90 (1.05–5.75) mg/L vs. 1.10 (0.5–3.65) mg/L) levels between CAD patients and CAD controls (Fig 1b–1d). Here, TNF is linked to coronary artery disorder.
