The triglyceride–glucose (TyG) index, an emerging surrogate marker of insulin resistance, has been implicated in adverse cardiovascular outcomes. However, its prognostic value critically ill patients with atrial fibrillation (AF) remains unclear. This study aimed to investigate the association between TyG index and all-cause mortality this high-risk population. We identified AF from Medical Information Mart for Intensive Care IV (MIMIC-IV) database categorized them into tertiles based on their levels. primary outcome was 30-day mortality, 90-day 365-day as secondary Cox proportional hazards regression analysis restricted cubic splines were used elucidate relationship mortality. Kaplan–Meier survival performed visualize differences among tertiles. A total 1473 included; 30-day, 90-day, rates 26.8%, 33.3%, 41.1%, respectively. Multivariate revealed that independently associated at 30 days [hazard ratio (HR) (95% confidence interval (CI)) 1.26 (1.09–1.45), P = 0.002], 90 [HR CI) 1.27 (1.11–1.45), < 0.001], 365 1.24 (1.10–1.40), 0.001]. Restricted showed a positive linear risk. curves further confirmed significant disparities across observed higher increased 30, 90, AF. underscores role key indicator risk stratification management intensive care.
