The Gut-Heart Connection: How Gut Bacteria Impact Heart Health

Certain gut bacteria, including species of Streptococcus found in the mouth and digestive tract, may be linked to the development of plaque buildup in the arteries, according to a study by Swedish researchers. The study analyzed gut bacteria and cardiac imaging of nearly 9,000 individuals and found that the presence of Streptococcus bacteria in the gut was associated with an increased occurrence of atherosclerotic plaques in the small arteries of the heart. The findings suggest a potential connection between oral bacteria, gut bacteria, and cardiovascular health, although further research is needed to establish a causal link.
