Objective:The aims of the study were to investigate the relationship among atherogenic index of plasma (AIP) and inflammatory adipocytokines with the severity of coronary artery calcification (CAC) score in coronary artery disease (CAD). And then we analyzed the diagnostic value of the new markers on CAC.Methods:A total of 241 patients with CAD diagnosed by coronary CT angiography (CTA) and coronary angiography in Baoding First Central Hospital from June 2019 to June 2020 were retrospectively enrolled. According to the presence of calcification in coronary CTA, they were divided into CAC group ( n=63) and non-CAC group ( n=178). The clinical data of the patients were collected, and the levels of serum inflammatory factors were measured by enzyme-linked immunosorbent assay (ELISA). The correlation between CAC score and AIP and inflammatory cytokines was analyzed. The diagnostic value of AIP and inflammatory factors in the formation of CAC in patients with CAD. Results:The levels of AIP, serum osteoprotegerin (OPG) and oligomeric matrix protein (COMP) in CAC group were higher than those in non-CAC group, while the levels of serum fibroblast growth factor 21 (FGF21) were lower than those in non-CAC group, with statistically significant difference (all P<0.01). Correlation analysis showed that CAC score of CAD patients was positively correlated with AIP, OPG and COMP ( r=0.581, 0.451, 0.326, P<0.05), and negatively correlated with FGF21 ( r=-0.294, P<0.05). Receiver operating characteristic (ROC) curve analysis showed that AIP, OPG, COMP and FGF21 had diagnostic value for CAC in CAD patients (all P<0.05). AIP>0.387, OPG>5.150 ng/ml, FGF21>136.35 pg/ml, COMP>733.16 ng/ml were independent factors affecting the formation of CAC (all P<0.05). Conclusions:The increase of AIP and the change of inflammatory factors can be used as markers for the diagnosis of CAC formation in CAD patients.
