Abstract：Objective To investigate the risk factors of coronary microvascular disease(CMVD)in elderly female patients.Methods Clinical data of 109 consecutive female elderly patients who re-ceived coronary angiography and coronary flow reserve(CFR)in our hospital from September 2020 to June 2022 were retrospectively collected in this study.According to CFR value,they were divided into CMVD group(CFR＜2.0,n=55)and non-CMVD group(CFR ≥2.0,n=54).The basic clinical data were compared between the two groups,and influencing factors associated with CMVD were analyzed.Results Significantly higher BMI and elevated UA,hs-CRP,TG,LDL and Lp-PLA2 levels,while lower HDL level was observed in the CMVD group than the non-CMVD group(P＜0.05,P＜0.01).Lp-PLA2 and hs-CRP were negatively correlated with CFR(r=-0.816;r=-0.399,P＜0.01).Spearman correlation analysis indicated that CRV value was nega-tively correlated with Lp-PLA2 and hs-CRP levels(r=-0.816,-0.399,P＜0.01).Logistic re-gression analysis showed that hs-CRP and Lp-PLA2 were independent risk factors for CMVD in elderly female patients(P＜0.05).ROC curve analysis revealed that the AUC value of Lp-PLA2 for diagnosing CMVD in elderly female patients was 0.745(95％CI:0.655-0.836),with a sensi-tivity of 69.1％and a specificity of 67.0％.And,the AUC value of hs-CRP was 0.752(95％CI:0.661-0.844).Conclusion Lp-PLA2 and hs-CRP levels are quite higher in elderly female CMVD patients,and can predict the occurrence of CMVD in elderly female patients.
