First, a positive correlation between the concentration of myeloperoxidase (MPO) and the level of high sensitivity C reactive protein (hsCRP) and interleukin 6 (IL‐6) in stable patients with CAD with MPO >300 ng/mL was seen; conversely, significant hsCRP, IL‐6, and TNF‐α reduction in patients with MPO<300 ng/mL was observed [19]. This evidence concerns the gene MPO and coronary artery disorder.
