Story summary

A study from Tampere University, Finland, connects oral bacteria to heart attacks by analyzing samples from over 200 coronary artery disease patients.
Researchers detected DNA from oral streptococci in arterial plaques, indicating a role in atherosclerosis.
These bacteria appeared in 42% of plaques from sudden cardiac death and surgical patients.
Inflamed bacterial biofilms can cause plaque rupture and heart attacks.
The findings emphasize the link between oral and cardiovascular health, suggesting new diagnostic and preventive approaches.
