Role of inflammatory factors in the development of in-stent restenosis
In-stent restenosis(ISR)is a significant cause of long-term prognosis after percutaneous coronary inter-vention(PCI).The inflammatory response is a critical factor in its development.Unlike the chronic inflammatory process of traditional atherosclerosis,ISR may develop acute coronary events within even months or years,and the inflamma-tory mechanisms of ISR are more complex.Inflammatory factors regulate various mechanisms,including monocyte macro-phage proliferation,endothelial cell damage and repair,foam cell formation,and smooth muscle cell proliferation and migra-tion after PCI.The review briefly describes the classification and risk factors of ISR.It emphasizes the role of various in-flammatory factors in ISR to provide new ideas for investigating the inflammatory mechanism of ISR and clinical intervention.
