Relationship between HOTAIR levels and the incidence of CIE in ACAS patients. A qRT-PCR was employed to identify serum levels of HOTAIR in CIE-positive and negative patients. B K-M survival curves were plotted based on the levels of HOTAIR in ACAS patients to evaluate the occurrence of CIE in patients with different levels of HOTAIR. *** P < 0.001, compared with CIE Negative group
