Relation of time in range to severity of coronary artery disease in patients with type 2 diabetes: A cross-sectional study
Abstract
Abstract Background Despite the high prevalence and serious clinical implications of coronary artery disease (CAD) in patients with type 2 diabetes mellitus (T2DM), the relationship between glycemic control and CAD is usually overlooked. This study aimed to explore the relationship between time in range (TIR), a surrogate marker for glycemic control, and CAD in patients with T2DM. Methods Overall, 334 patients with T2DM were included and analyzed in this cross-sectional study. The presence of CAD was determined angiographically and the Gensini score was applied to evaluate CAD severity. TIR was calculated from sensor glucose from continuous glucose monitoring. Multivariable-adjusted logistic regression analysis was used to evaluate the relationship between TIR and CAD presence. Results T2DM with CAD had significantly lower TIR than those without (75.68 ± 13.74 vs 66.12 ± 11.87, P < 0.01). Moreover, TIR was correlated with CAD severity as indicated by the Gensini score. Multivariable-adjusted logistic regression analysis indicated that a higher TIR was an independent protective factor for CAD in patients with T2DM (OR = 0.919, 95% CI: 0.896–0.942). Conclusion TIR is significantly and independently related to CAD severity in T2DM patients. Thus, TIR could be a promising biomarker for the noninvasive assessment of CAD presence and severity in T2DM.
