Is elevated triglyceride-glucose (TyG) index associated with atrial fibrillation in hospitalized cardiology patients?
Elevated triglyceride-glucose index may serve as an independent risk marker for atrial fibrillation in non-diabetic hospitalized cardiology patients.
Background: Insulin resistance is associated with atrial remodeling as well as atrial fibrillation (AF). However, there was limited evidence on the relationship of triglyceride-glucose index (TyG) index, a simple, valuable marker of insulin resistance, with AF. Thus, we aimed to investigate the association between TyG index and AF among hospitalized patients. Methods: A retrospective observational study was conducted in Daping Hospital, which included 356 hospitalized patients from the Department of Cardiology. Clinical and biochemical parameters were collected from electronic medical records and AF was diagnosed from electrocardiogram (ECG) findings. Results: <0.001) in non-diabetic subjects. However, TyG index was not associated with AF in diabetic subjects. Conclusion: Elevated TyG index is an independent risk factor for AF among non-diabetic hospitalized patients.
