(ORDO NEWS) — Ischemic disease is the most common cause of death today.
Its development can be stimulated not only by smoking and a sedentary lifestyle, but also by ordinary fusobacteria that live in the mouth of almost every person.
Coronary artery disease (CHD) is associated with insufficient blood supply to the heart muscle. Its manifestations, including heart attack, are the leading cause of death in the modern world.
IHD begins with the accumulation of sclerotic plaques in the coronary (heart) arteries, which impede normal blood flow in the myocardium and lead to coronary insufficiency.
Therefore, an increased risk of developing the disease is associated with a whole range of factors – from hereditary and age-related to unhealthy lifestyle and unhealthy diet.
Another unexpected cause of CHD was found in the oral cavity. Plaque buildup is facilitated by infections and chronic inflammation, and can be caused by common bacteria in the mouth.
This conclusion was made by scientists from the Swiss Federal Polytechnic School of Lausanne
Flavia Hodel and her colleagues conducted a longitudinal (long-term) health study in nearly 3,500 volunteers, which lasted more than 12 years.
Among other parameters, the scientists tracked blood levels of C-reactive protein , which serves as a marker of inflammation. In addition, scientists regularly tested subjects for infection with 22 common pathogens.
One of these pathogens was Fusobacterium nucleatum , which is found in the oral cavity of most people.
They look like long thin sticks and are normally not too dangerous, but if they manage to infect mucosal cells, this can lead to the development of periodontitis and gingivitis.
In more rare and dangerous situations, fusobacteria penetrate even lower into the gastrointestinal tract, causing more serious diseases.
Observations by Swiss scientists have shown that even successfully completed Fusobacteria infections correlate with an increased risk of developing coronary disease.
The authors of the article attribute this not only to inflammation, but also to the ability of microbes to migrate into the coronary (heart) arteries and attach to their walls, stimulating the accumulation of plaques.
