New findings published in a cardiology journal highlight a link between gum disease and heart rhythm problems. Inflammation around teeth, known as periodontitis, may raise the risk of developing arrhythmias later on.
Atrial fibrosis, the unusual growth of connective tissue in the atria, can set the stage for atrial fibrillation, a common irregular heartbeat.
In a study conducted by researchers at a university in Japan, 76 participants with left atrial fibrosis underwent surgery to remove the left atrial appendage. Tissue samples from these patients were examined, revealing a connection between how severe atrial fibrosis was and the presence of periodontitis.
One explanation is that periodontitis drives long term inflammation, a key factor in the progression of fibrosis. The association remained even after controlling for age, expected longevity with fibrosis, body mass index, and other health conditions.
It is important to note that the study does not prove that gum disease causes atrial fibrosis or atrial fibrillation. The researchers emphasize this point and call for follow up clinical trials to test whether treating periodontitis can lower the incidence of atrial fibrillation.
Beyond dental care, several lifestyle steps can help reduce heart rhythm risks. Quitting smoking, maintaining a healthy weight, staying physically active, and moderating or avoiding alcohol intake are all associated with lower chances of developing arrhythmias.
