Compared to patients with stable CAD, patients with ACS had decreased levels of IL-4 (p = 0.005) and increased levels of hepatocyte growth factor (HGF) (p < 0.001), macrophage colony-stimulating factor (M-CSF) (p = 0.002) and IL-8 (p = 0.008). This evidence concerns the gene IL4 and coronary artery disorder.
