Heart attacks are linked to intestinal bacteria – Dagens PS

“increased incidence”

“We found that common bacteria in the oral cavity, especially the different types of Streptococcus aureus, when we find them in the gut, are associated with an increased appearance of plaque in the small arteries of the heart,” he says. Tove Fall Professor of Molecular Epidemiology at Uppsala, who coordinated the study with researchers from Lund University.

Streptococcus aureus is a known cause of pneumonia and infections of the throat, skin, and heart valves. We now need to further investigate whether these bacteria also contribute to the development of atherosclerotic plaques and heart attacks,” adds Tove Fall.

Defines new relationships

“The large number of samples with high-quality information on coronary plaque composition and gut flora composition allowed us to identify new relationships,” he says. Sergi Sayulis Baixerasa researcher at Uppsala University and one of the study’s lead authors.

“We are just beginning to understand how humans and the bacterial communities in different parts of the body affect each other. Our study shows that cardiovascular health is worse in carriers of streptococcus in the gut.” Margo Urho MelanderProfessor of Genetic Epidemiology at Lund University, one of the study’s lead authors.
