Association between triglyceride-glucose index and all-cause mortality in patients underwent transcatheter aortic valve replacement.

ABSTRACT:

Backgrounds

The prognosis of the triglyceride-glucose (TyG) index, a validated surrogate marker for insulin resistance, in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR) remains unknown.

Methods

This study consecutively enrolled patients diagnosed with severe AS who underwent TAVR in a Chinese tertiary hospital from March 2013 to September 2023. Participants were stratified based on the TyG index cut-off value. Cox proportional hazards regression models were utilized to explore the association between the TyG index and all-cause mortality, including an assessment of interactions between the TyG index and various covariates on mortality outcomes.

Results

Among 1045 patients (mean age 74.7 years, 58.2% male), there was
