Health

Objective The association between the Triglyceride-Glucose (TyG) Index and mortality rates in patients with cardiovascular disease (CVD) remains unclear. This study investigates the association between the TyG index and the incidence of all-cause and CVD-specific mortality among individuals with a history of CVD. Design Population-based cohort study. Setting Data were sourced from the US National Health and Nutrition Examination Survey (2007–2018) and linked mortality data, with follow-up continuing until 31 December 2019.
