Elevated plasma TMAO levels are associated with a higher risk of recurrent ASCVD in individuals with preexisting cardiovascular disease, independent of renal function status.

If you have a history of heart disease, higher TMAO levels are linked to a higher risk of another heart event. This risk exists regardless of your kidney function. Discussing TMAO levels with your cardiologist may help tailor your prevention strategy.
