Abstract：Objective To explore the relationship between CT fat attenuation index(FAI)of pericoronary adipose tissue(PCAT)and coronary atherosclerosis,plaque properties.Methods A total of 138 patients undergoing coronary CT angiography(CTA)in the hospital from January 2022 to December 2024 were retrospectively analyzed.FAI value of PCAT in all patients was measured to analyze its relationship with coronary atherosclerosis and plaque properties.Results There were 206 lesions in all the 138 patients.FAI value of PCAT has certain relationship with coronary stenosis and plaque properties.FAI value in plaques with mild,moderate and severe coronary stenosis was greater than that with slight stenosis,and which was gradually decreased in non-calcification plaques,mixed plaques and calcification plaques(P<0.05).The results of multiple linear regression analysis showed that FAI value was positively correlated with plaque properties(P<0.05).Conclusion FAI value of PCAT has certain correlation with coronary atherosclerosis and plaque properties.Measuring FAI value around plaques with high risk of unstable inflammation is beneficial to clinically evaluate the risk of coronary heart disease.
