<h4>Introduction</h4>This study investigated the relationship between the serum aspartate aminotransferase to alanine aminotransferase (AST/ALT) ratio, the presence and progression of abdominal aortic aneurysms (AAA), assessing its potential as an accessible biochemical marker for patients at risk of rapid aneurysmal growth.<h4>Methods</h4>A total of 180 patients were retrospectively analyzed: 90 with AAA and 90 ageand risk factor-matched controls. Here, GPT is linked to abdominal aortic aneurysm.
