Circulating Trimethylamine N-Oxide and Growth Rate of Abdominal Aortic Aneurysms and Surgical Risk

Results of this cohort study suggest that elevated circulating TMAO levels were associated with increased risk of AAA and identified patients at heightened risk for fast-growing AAA and recommended surgical intervention. TMAO may help identify individuals who may benefit from more frequent surveillance imaging and early surgical intervention to prevent aortic dissection or rupture.
