The carriers of CT genotype had higher levels of systolic blood pressure (SBP), low‐density lipoprotein cholesterol (LDL‐C), and high‐sensitivity C‐reactive protein (hs‐CRP), and lower levels of apolipoprotein A1 (APOA1) than those with CC genotype in male patients with CAD. Here, CRP is linked to coronary artery disorder.
