摘要
Objective To investigate the association between long-term glycemic control and cerebral infarction risk in patients with diabetes through a large-scale cohort study.Methods This prospective,community-based cohort study included 12,054 patients with diabetes.From 2006 to 2012,38,272 fasting blood glucose(FBG)measurements were obtained from these participants.FBG trajectory patterns were generated using latent mixture modelling.Cox proportional hazards models were applied to assess the subsequent risk of cerebral infarction associated with different FBG trajectory patterns.Results At baseline,the mean age of the participants was 55.2 years.Four distinct FBG trajectories were identified based on FBG concentrations and their changes over the 6-year follow-up period.After a median follow-up of 6.9 years,786 cerebral infarction events were recorded.Different trajectory patterns were associated with significantly varied outcome risks(Log-Rank P<0.001).Compared with the low-stability group,Hazard Ratio(HR)adjusted for potential confounders were 1.37 for the moderate-increasing group,1.23 for the elevated-decreasing group,and 2.08 for the elevated-stable group.Conclusion Sustained high FBG levels were found to play a critical role in the development of ischemic stroke among patients with diabetes.Controlling FBG levels may reduce the risk of cerebral infarction.
