Association of Triglyceride–Glucose Index with Heart Failure with Preserved Ejection Fraction and Diastolic Dysfunction in Patients with Type 2 Diabetes Mellitus: A Cross-Sectional Study
Background: Heart failure with preserved ejection fraction (HFpEF) is increasingly recognized as a major cardiovascularcomplication in patients with type 2 diabetes mellitus (T2DM). Insulin resistance plays a central role in the pathogenesis ofHFpEF, and the triglyceride–glucose (TyG) index has emerged as a simple surr...
