We assessed whether the plasma IL-37, IL-18, and IL-18BP levels were associated with lipid and lipoprotein fractions (triglycerides, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol), fasting glucose, CRP, NT-proBNP, LVEF, LVEDD, and the Gensini score in patients with CAD. The gene discussed is NPPB; the disease is coronary artery disorder.
