As to inflammation‐related indexes and cell adhesion molecules, MiR‐34a expression was positively linked with C‐reactive protein (p < 0.001), tumor necrosis factor alpha (p = 0.005), interleukin (IL)‐1β (p = 0.020), IL‐17A (p < 0.001), vascular cell adhesion molecule‐1 (p < 0.001), and intercellular adhesion molecule‐1 (p = 0.010) in CHD patients, but not with IL‐6 (p = 0.118) and IL‐10 (p = 0.054). The gene discussed is IL17A; the disease is coronary artery disorder.
