Usefulness of triglyceride-glucose index and homeostatic model assessment for predicting coronary microvascular dysfunction.

Background: Coronary microvascular dysfunction (CMD) is a common occurrence in individuals with insulin resistance (IR). Homeostatic model assessment for insulin resistance (HOMA-IR) is a widely used surrogate marker of IR, although recent studies suggest triglyceride-glucose (TyG) index is a superior marker of IR that had a better accuracy to predict type 2 diabetes or cardiovascular outcomes than HOMA-IR.

Objectives: We aimed to assess the accuracy and usefulness of TyG index and HOMA-IR for predicting CMD as assessed with echocardiographic coronary flow reserve (CFR) measurement.
