The Claim

The relative abundance of Streptococcus and Actinomyces in the oral microbiome is associated with a reduced risk of major adverse cardiovascular events in middle-aged adults.

In plain English

Middle-aged adults with higher levels of Streptococcus and Actinomyces in their mouth microbiome have a lower incidence of major cardiovascular events such as heart attacks and strokes.

See the scientific wording

The relative abundance of Streptococcus and Actinomyces in the oral microbiome is associated with a reduced risk of major adverse cardiovascular events in middle-aged adults, suggesting these genera may play a protective role in cardiovascular health.

Why this might work

Good bacteria in the mouth crowd out harmful ones, preventing them from entering the bloodstream and triggering inflammation in blood vessels. When harmful bacteria are kept in check, blood vessels stay healthier and less likely to develop dangerous plaques that cause heart attacks and strokes.

  1. Study: An oral microbiome model for predicting atherosclerotic cardiovascular disease

    This study found that people with more of two common mouth bacteria, Streptococcus and Actinomyces, were less likely to have heart attacks or strokes, suggesting these bacteria might help protect the heart.
