Objective To investigate the correlation between arteriosclerotic cardiovascular disease (ASCVD) and time in range (TIR) in elderly patients with diabetes.Methods The patients with type 2 diabetes mellitus (T2DM,n=158) were chosen from Affiliated Hospital of Xuzhou Medical University from Nov.2020 to Oct.2023,and divided,according to whether they had ASCVD or not,into ASCVD group (n=72) and non-ASCVD group (n=86).Clinical materials were collected from all patients,and clinical features and blood glucose indexes were compared between 2 groups.A generalized linear mixed model was established to determine the relationship between blood glucose indexes and ASCVD in T2DM patients.The patients were further divided,according to TIR level,into quartile subgroups Q1,Q2,Q3 and Q4 in an ascending order.The correlation between TIR and ASCVD in T2DM patients was analyzed in subgroups.Results Among 158 patients with T2DM,45.57% of patients suffered from ASCVD.In ASCVD group,age,diabetes course,hypertension proportion and levels of fasting blood glucose (FPG),total cholesterol (TC) and homocysteine (Hcy) were significantly higher than those in non-ASCVD group (P<0.05).The results of generalized linear mixed model analysis showed that TIR was a protective factor for ASCVD occurrence in T2DM patients.The indexes of time above range (TAR),mean glucose (MG),standard deviation of blood glucose (SDBG) and largest amplitude of glycemic excursion (LAGE) were risk factors for ASCVD occurrence in T2DM patients.The results of subgroup analysis on correlation between TIR level and ASCVD showed that TIR level was more significantly correlated to ASCVD (Pinteraction=0.025) in patients aged≥68 compared with patients aged<68.Conclusion The level of TIR is significantly lower in ASCVD group than that in non-ASCVD group.After adjusting confounders,TIR level is still significantly correlated to ASCVD risk in T2DM patients.
