The high density lipoprotein cholesterol (HDL‐C), fasting plasma glucose (FPG), chemerin, ox‐LDL, MMP‐9, and PPAP‐A levels in the ACI group were significantly higher than those in the TIA group and control group (p < 0.05, respectively), while the levels of the mentioned indicators in the TIA group were significantly higher than those in control group (p < 0.05, respectively). Here, MMP9 is linked to transient ischemic attack.
