Abstract:
Objective To explore the correlation between coronary fat attenuation index of perivascular adipose tissue(FAIPVAT),as well as volumetric perivascular characterization index(VPCI),and coronary heart disease(CHD).Methods A total of 112 patients who underwent coronary computed tomography angiography(CCTA)and coronary angiography(CAG)examinations within 2 weeks were selected.The patients were divided into CHD group and control group according to the degree of coronary artery stenosis,and were divided into calcified plaque group,non-calcified plaque group and mixed plaque group according to the nature of plaque.The correlation between FAIPVAT,VPCI and CHD were evaluated.Results Of the 112 patients,71 patients in the CHD group and 41 patients in the control group.There were significant differences in gender,age,FAIPVAT and VPCI between the two groups.FAIPVAT and VPCI were positively correlated with CHD(r=0.445,P＜0.01;r=0.669,P＜0.01).FAIPVAT and VPCI were analyzed by receiver operating characteristic(ROC)curve,the area under the curve(AUC)of FAIPVAT was 0.770,the cut-off value was-81.659 HU,the sensitiv-ity was 0.592,and the specificity was 0.878,while the AUC of VPCI was 0.892,the cut-off value was 8.056,the sensitivity was 0.887,and the specificity was 0.805.There were significant differences in FAIPVAT and VPCI between non-calcified plaque group and calci-fied plaque group.FAIPVAT and VPCI of mixed plaque group and calcified plaque group were significantly different.Conclusion FAIPVAT and VPCI have some certain correlation with CHD.FAIPVAT and VPCI can accurately evaluate the risk level of CHD and coronary artery inflammation,and the value of individualized VPCI is higher.
