Gut health seems to be implicated in just about everything these days. Now, emerging research is showing a link between the gut microbiome and mechanisms associated with coronary artery disease.

According to a Nov. 6, 2025 press release from the American Society for Microbiology, researchers in Seoul, South Korea compared fecal samples from 14 people with coronary artery disease to those of 28 healthy people using metagenomic sequencing. Through this method, the research team identified 15 bacterial species associated with coronary artery disease, as well as the pathways through which the gut microbes impact disease progression.

The study also found that even strains of “good” bacteria can become harmful to cardiovascular health depending on whether the subject’s overall gut health is in a positive or negative state. The study authors’ next step is to leverage metabolomic and genetic data to map microbes to specific disease pathways.
