Abstract:
Objective To investigate the relationship of triglyceride-glucose(TyG)index and atherogenic index of plasma(AIP)with positive remodeling of coronary arteries in elderly coro-nary heart disease(CHD)patients with concomitant type 2 diabetes mellitus(T2DM).Methods A total of 120 elderly CHD patients with concomitant T2DM admitted to our department from January 2022 to June 2023 were continuously recruited,and according to the remodeling index,they were divided into positive remodeling group(47 cases)and non-positive remodeling group(73 cases).The clinical data were compared between the two groups.Multivariate logistic analysis was used to identify the risk factors for positive remodeling of coronary artery.Spearman correla-tion analysis was employed to analyze the correlation of TyG and AIP with positive remodeling.ROC curve was plotted to analyze the predictive value of TyG and AIP for the remodeling.Results The positive remodeling group had larger ratio of smoking,higher TG and HbA1c levels,and in-creased TyG index and AIP,but lower HDL-C and blood calcium levels than the non-positive re-modeling group(P＜0.05,P＜0.01).Univariate logistic regression analysis showed that smoking,TG,HDL-C,HbA1c,blood calcium,TyG and AIP were risk factors for positive coronary artery remodeling in elderly patients with CHD and T2DM(P＜0.05,P＜0.01).Multivariate logistic re-gression analysis showed that TyG index(OR=7.253,95％CI:2.458-13.364,P=0.035)and AIP(OR=6.017,95％CI:2.205-12.025,P=0.030)were independent risk factors for positive coronary artery remodeling in elderly patients with CHD and T2DM(P＜0.05).The AUC value of TyG index and AIP in predicting positive coronary artery remodeling in elderly CHD patients with T2DM was 0.783 and 0.766,respectively,and the value of their combination in the prediction was 0.868,which was significantly better than the indicator alone(P＜0.05).Conclusion TyG in-dex and AIP are closely associated with positive coronary artery remodeling in elderly CHD pa-tients with T2DM,and can be used as effective indicators in the prediction of positive remodeling,which is of great significance for early clinical identification of high-risk patients and formulation of individual intervention strategies.
