- Atrial fibrillation affects 1% of the general population, according to Health Insurance.
- 20 to 30% of strokes are secondary to atrial fibrillation.
It is estimated that severe periodontitis affects approximately 19% of the world’s adult population, or more than 1 billion people worldwide, according to World Health Organization (Who is the). This chronic inflammatory disease of the mouth gradually destroys the supporting apparatus of the teeth and, if left untreated, can lead to loosening and loss of teeth.
Gingivitis Promotes fibrosis
According to a new study published in the journal JACC: Clinical ElectrophysiologyPeriodontitis can also cause heart problems. “Periodontitis is associated with inflammation [présente depuis longtemps] Inflammation plays a major role in the development of fibrosis and atrial fibrillationShunsuke Miyauchi, one of the authors, explains in a communication. We hypothesized that periodontitis promotes fibrosis.”
Researchers define fibrosis as scarring of the left atrial appendage (LAA), a small cavity in the left atrium of the heart, which can lead to an irregular heartbeat called atrial fibrillation. This is defined by health insurance Such as a heart arrhythmia that causes palpitations. Among the risk factors for this disease are age, obesity, diabetes, sleep apnea, hyperthyroidism, etc.
To test their hypothesis that gum promotes fibrosis and thus atrial fibrillation, the scientists studied health data from 76 patients with heart disease. Specifically, the researchers analyzed tissue samples from the participants’ agases.
Periodontitis: a novel risk factor for atrial fibrillation
Results: They found that the more severe the periodontitis, the more severe the fibrosis. Thus, they believe that periodontitis can promote atrial fibrillation.
“This study provides evidence that periodontitis can exacerbate fibrosis and be a novel risk factor for atrial fibrillation.”says Yukiko Nakano, one of the authors. Thus, she hopes that through this work, this disease can be taken into account among the risk factors.
“More evidence is needed to demonstrate that periodontitis contributes causally to atrial fibrosis and that periodontal care can modify fibrosis.Shadow Yukiko Nakano. One of our goals is to confirm that periodontitis is a modifiable risk factor for atrial fibrillation and [d’inclure les dentistes] In the comprehensive treatment of atrial fibrillation. Periodontitis is a modifiable risk factor (…) for atrial fibrillation.“
