A new investigation detected the presence of oral bacteria in over 40% of heart signs of heart patients.
Bacteria often found in the mouth can contribute directly to heart attacksaccording to a new investigation from the University of Tampere, Finland. The, published in the Journal of the American Heart Association, provides some of the most solid evidence to the date that connects oral health to cardiovascular disease.
Scientists examined Arterial signs of more than 200 patients with coronary arterial disease. The samples come from 121 individuals who died suddenly and 96 patients who underwent surgery to remove the plate. Using advanced techniques, including polymerase chain reaction analysis, immunohistochemistry and transcriptomic, the researchers discovered genetic material of oral bacteria within many of the plates.
One of the most frequently identified organisms was the Viridan streptococcal group, common in human mouth. According to the, the oral streptococci were detected in 42.1% of samples of patients with sudden death and in 42.9% of patients undergoing surgery.
“Bacterial involvement in coronary arterial disease has been suspected for a long time, but direct and convincing evidence is missing“Tampere doctor said Pekka Karhunen.“ Our study demonstrated the presence of DNA from various oral bacteria within atherosclerotic plates. ”
Atherosclerosis, the accumulation of plaques within the coronary arteries, is a major cause of heart attacks. The plates narrow the blood vessels, restrict blood flow and may breakleading to cardiac stop. The Finnish study found that bacterial biofilms were often located at the nucleus of these plates, beyond the reach of the body’s immune system.
The correlation between the presence of oral bacteria and severe atherosclerosis, sudden cardiac death and plate rupture suggests that the poor oral health can have a much stronger impact in heart health of what was imagined earlier.
The findings open new paths for both prevention and treatment. Better oral hygiene and early detection of bacterial biofilms may one day play a role in reducing the risk of heart disease.
