Gut bacteria linked to fatty deposits in heart arteries

A major study in Sweden has found a connection between specific gut bacteria and the development of coronary atherosclerotic plaques, which can lead to heart attacks. The study analyzed gut bacteria and cardiac imaging in nearly 9,000 participants without previously known heart disease. The researchers discovered that certain oral bacteria, particularly from the Streptococcus genus, were associated with an increased occurrence of atherosclerotic plaques in the small arteries of the heart when present in the gut. The study also found that the same bacteria were linked to levels of inflammation markers in the body. The findings highlight the need for further research on the relationship between gut bacteria and cardiovascular health.
