Time in range (TIR) refers to the time or percentage of time within 24 h that glucose levels are in the target range; or the time that blood glucose levels are higher and lower the target range. TIR is a core parameter of continuous glucose monitoring (CGM) and an important indicator for the evaluation of blood glucose in treatment of diabetic patients. Recent studies have confirmed that TIR is closely related to cardiovascular complications of diabetes, and it may become a key indicator for predicting the risk of cardiovascular complications in the future. This article reviews the research progress on the relationship between TIR and cardiovascular complications in diabetic patients, and discusses the value of TIR in the integrated management of diabetes and cardiovascular diseases.

Diabetes has become a global public health problem due to its high incidence, severe complications and prolonged illness. The ideal cardiovascular health behaviors and factors provide a straightforward and simple way to quantify important health behaviors and factors, and clear and operable targets for cardiovascular disease prevention. A growing number of studies confirm that having more ideal cardiovascular health behaviors and factors is also associated with a lower risk of diabetes. This article reviews the relationship between ideal cardiovascular health behaviors and factors and the occurrence and development of diabetes and its complications, and explores the value of ideal cardiovascular health behaviors and factors in the primary, secondary and tertiary prevention of diabetes.
