Previous studies have demonstrated that the triglyceride-glucose (TyG) index is significantly associated with vascular damage. Albuminuria is a marker of hypertension-mediated organ damage (HMOD) and has been linked to a greater risk of cardiovascular disease (CVD). However, the association between the TyG index and albuminuria in patients with hypertension is not clear. This population research focused on subjects with hypertension to investigate the association between an elevated TyG index and albuminuria.
