Interplay Among Gut Microbiota-Derived TMAO, Autonomic Nervous System Dysfunction, and Heart Failure Progression
2025
Overview
The gut microbiota is crucial for metabolic homeostasis and cardiovascular health. Dysbiosis triggers a gut–brain–heart axis dysfunction: vagal signaling promotes neuroinflammation and cerebral damage, which in turn impairs cardiac function. This bidirectional cycle is further exacerbated by reduced cerebral perfusion. Trimethylamine-N-oxide (TMAO), a metabolite of dietary choline and L-carnitine, acts as a primary mediator in this network. Elevated TMAO levels—resulting from bacterial conversion and hepatic oxidation—are linked to atherosclerosis and heart failure. Mechanistically, TMAO activates the NLRP3 inflammasome, inhibits the SIRT3-SOD2 pathway, and promotes platelet hyperreactivity. Furthermore, it modulates the autonomic nervous system, enhancing sympathetic activity and cardiac arrhythmias. Clinical evidence suggests TMAO is a potent predictor of mortality in HF. While current HF therapies focus on end-organ response (beta-blockers) or humoral pathways (ACE inhibitors), directly targeting the microbiota and TMAO offers a novel therapeutic frontier. Integrating TMAO assessment into risk models and utilizing advanced in vitro gut–brain models will be essential for developing personalized, groundbreaking cardiovascular interventions. Within this framework, the main aim of the present review is to describe how cardiac autonomic control can be directly modulated by the microbiota and its byproducts like TMAO. This latter is a leading target candidate for novel HF prevention and therapy interventions.
