Association between triglyceride glucose index and all-cause mortality in patients with critical atrial fibrillation in the MIMIC-IV database.

ABSTRACT: Although several studies have demonstrated the relationship between the triglyceride glucose (TyG) index and the prevalence of atrial fibrillation (AF), more attention needs to be paid to patients with AF in intensive care units because the prevalence of AF is as high as one-third of the population. This study investigated the relationship between the TyG index and short-term prognosis in patients with critical care AF. We selected critically ill patients with AF from the MIMIC-IV database and categorized them into quartiles based on their TyG index levels. The primary outcome assessed was 30-day all-cause mortality, with secondary outcomes of 7-day and 15-day all-cause mortality. We utilized Kaplan-Meier survival curves, restricted cubic spline, and Cox proportional hazards regression mod
