Atherosclerotic cardiovascular diseases(ASCVD)are chronic progressive diseases characterized by endothelial dysfunction,and their traditional therapies have limitations.In recent years,nanocarrier systems have demonstrated significant advantages in targeted delivery,enhancing drug safety and efficacy,thereby offering new strategies for precise diagnosis and treatment of ASCVD.Nanomaterials,including polymer nanoparticles,lipid nanoparticles,inorganic nanoparticles and bio-inspired nanoparticles,can effectively intervene key pathological processes of ASCVD.They achieve therapeutic effects by regulating macrophage balance,preserving endothelial cell function,maintaining smooth muscle cell contractile phenotype and modulating platelet activity.This review summarizes the application characteristics and research progress of different types of nanomaterials in the prevention and treatment of ASCVD,and provides insights into the challenges and future prospects of this field.
