Intestinal bacteria (germs) have been shown to influence the accumulation of fat in the arteries of the heart and the risk of future heart attacks.
A joint research team from Uppsala University and Lund University in Sweden found an association between levels of certain microbes in the gut and coronary artery atherosclerotic plaques. Atherosclerosis can occur when atherosclerotic plaque builds up in the arteries. Atherosclerosis is one of the causes of heart attacks and strokes.
The research team analyzed gut bacteria and heart images of more than 9,000 Swedes between the ages of 50 and 65 without heart disease.
“We found that the presence of oral bacteria, particularly species of the genus Streptococcus, in the gut was associated with an increased incidence of atherosclerotic plaques in the small arteries of the heart,” said Professor Tove Paul of Uppsala University (molecular epidemiology) of the research team. did,” he said.
“Streptococcus bacteria are a common cause of pneumonia and infections of the throat, skin and heart valves,” said Professor Paul. “We need to determine whether these bacteria contribute to the development of atherosclerosis.”
“Advanced technology that can analyze and compare the DNA content of biological samples is helpful for this study,” said the research team. Explained.
Dr. Serge Sayols-Baiceras of the research team said, “We were able to confirm the new association through many samples, including high-quality data from cardiac imaging and intestinal flora. The most important findings include Streptococcus anginosus and Streptococcus It was two bacteria,” he said.
These bacteria are associated with markers of inflammation in the blood. Several species associated with arterial fat accumulation also appeared to be associated with levels of the same species in the mouth.
“We are just beginning to understand how the human host and bacterial communities in different compartments of the body affect each other,” said Marju Orho-Melander, a professor of genetic epidemiology at the University of Lund, who led the research team. “It shows that people with streptococci have worse cardiovascular health.”
The results of this study (Streptococcus Species Abundance in the Gut Is Linked to Subclinical Coronary Atherosclerosis in 8973 Participants From the SCAPIS Coho) were published in the cardiovascular journal ‘Circulation’.
