APOB and Disorder of lipid metabolism: The lipid metabolism disorder in ACS patients is triggered by the joint action of multiple effector cells and cytokines.10 In addition, macrophages transformed from monocytes in serum are the initiating cells of plaque formation in ACS.11 Macrophages phagocytize LDLC and its apolipoprotein ApoB lipid particles and deposits on the vascular endothelium.12 After gathering to a certain extent, macrophages transform into foam cells, and then rupture and die, thereby contributing to the malignant development of ACS.
