Notably, the differences of most clinical features were of no significance between CHD patients and controls, including body mass index (BMI), family history of CHD, comorbidities, fasting blood glucose (FBG), serum creatinine (Scr), serum uric acid (SUA), triglyceride (TG), high‐density lipoprotein cholesterol (HDL‐C) (all p > 0.050), except the proportion of smoking (p = 0.022), DM (p = 0.050), total cholesterol (TC) (p = 0.001), low‐density lipoprotein cholesterol (LDL‐C) (p < 0.001), and C‐reactive protein (CRP) (p = 0.010) (Table 1). The gene discussed is CRP; the disease is coronary artery disorder.
