Key Points

To investigate the relationship between the AST/ALT ratio and the presence and progression of abdominal aortic aneurysms (AAA).
Conducted a cross-sectional study analyzing serum AST and ALT levels.
Evaluated patients for the presence of AAA using imaging techniques.
Analyzed the correlation between the AST/ALT ratio and the progression of AAA.
An elevated AST/ALT ratio was linked to the presence of AAA.
The AST/ALT ratio did not independently predict AAA progression.
Findings suggest that the ratio may indicate an inflammatory interaction between the liver and blood vessels.

Abstract

An elevated AST/ALT ratio is associated with AAA presence but does not independently predict progression, suggesting it reflects hepatic-vascular inflammatory interaction rather than serving as a prognostic marker.
