High TMAO Levels Predict Abdominal Aortic Aneurysm Progression and Surgical Risk: JAMA

USA: A study published in JAMA Cardiology has found that circulating levels of trimethylamine N-oxide (TMAO), a metabolite produced by gut microbiota, may serve as an important biomarker in predicting the risk of abdominal aortic aneurysms (AAA), their growth rate, and the likelihood of surgical intervention.
- Elevated TMAO levels showed a consistent and significant association with abdominal aortic aneurysm outcomes.
- In the European cohort, higher TMAO was linked to a 2.75-fold greater risk of rapid aneurysm growth and a 2.67-fold higher likelihood of surgical recommendation.
- In the US cohort, elevated TMAO corresponded to a 2.71-fold increased risk of fast-growing aneurysms and a 2.73-fold higher chance of surgery.
- Combined analysis of both cohorts confirmed more than double the adjusted risk for both accelerated aneurysm progression and surgical need.
- Incorporating TMAO levels into cardiovascular risk models improved prediction accuracy for aneurysm growth and surgical requirement.
- The findings suggest that individuals with elevated TMAO may benefit from closer surveillance and earlier intervention to prevent rupture or dissection.
