A low lymphocyteand high neutrophil count are typical inflammatory responses associated with thedevelopment of atherosclerotic plaque and stent implantation [22, 23, 24].Furthermore, RC can also induce an inflammatory response via the production ofcytokines and interleukins through the plasminogen activator inhibitor-1 [25].Taken together, RCLR is a good indicator for predicting MACE, as it considers theeffects of atherosclerosis and inflammation. Here, SERPINE1 is linked to atherosclerosis.
