Gut microbiota: metabolites at the heart of cardiovascular risk

Coronary heart disease remains the leading cause of mortality worldwide. Its development relies on a complex interplay of genetic, metabolic, and environmental factors. Among these, the role of the gut microbiota has attracted growing interest. Acting as a true metabolic organ, it produces a wide range of molecules capable of entering the bloodstream and influencing host physiology—sometimes in harmful ways.  

A study published on March 17 in PLOS Medicine aimed to better understand the links between microbial metabolites and the risk of coronary heart disease. The researchers sought to identify, using large-scale human data, metabolic signatures associated with the onset of this cardiovascular condition.
