April 10 (UPI) — New Japanese research published Wednesday shows that treating gum disease within three months of surgery can reduce the recurrence of atrial fibrillation in patients undergoing catheter cardiac ablation.

A two-year study of 288 patients at Hiroshima University Hospital found that gingival inflammation was a strong predictor of recurrence of AFib after non-surgical ablation, and the team believes there is a correlation between reducing oral inflammation and lowering the likelihood of recurrence of heart flutter — —The American Heart Association said in a press release that they were unable to establish a linkage mechanism.

The study, published in the Journal of the American Heart Association, is one of the first to examine how gum inflammation affects AFib and calls for routine gum disease screenings for AFib patients and guidance on treatment for those with the disease, according to dental research. Provided by service provider.

The association says that given that AFib increases an individual's risk of stroke by 500 percent, it is expected to affect more than 12 million Americans by 2030, and data from the Centers for Disease Control shows that about half of U.S. adults age 30 and older have some type of disease. A form of periodontal, or gum, disease, the incidence of which increases with age.

“Gum disease can be improved through dental intervention. Appropriate treatment of gum disease appears to improve the prognosis of AFib, and many people around the world could benefit from it,” said the study's lead author, Dr. Shunsuke Miyauchi, assistant professor at Hiroshima University School of Medicine. . Health Services Center.

By comparing 97 patients who underwent radiofrequency catheter ablation and treatment for gum inflammation with 191 ablation patients who did not receive treatment for gum disease, the team found that 24% of patients experienced recurrence of AFib during the follow-up period of 8.5 to 24 months. However, the recurrence rate was lower in the treatment group of 61%.

Notably, about a quarter of patients who relapsed from AFib had more severe gum disease than those who did not have a recurrence of AFib, an association that was confirmed using a standard index used by dentists to measure the severity of gum inflammation.

“While the main findings were consistent with their expectations, we were surprised by how useful a quantitative index of gum disease, called periodontal inflammatory surface area, or PISA, was in cardiovascular clinical practice,” Miyauchi said, stressing that a multicenter study Randomized studies are needed to confirm the results.

Miyauchi explained that other predictors of AFib include being female, experiencing an arrhythmia for more than two years, and increased left atrial size and its associated thickening and scarring of connective tissue.

“We are now conducting further studies to uncover the underlying mechanisms of the relationship between gum disease and AFib,” he said

The American Heart Association says that while it does not currently list oral health as a risk factor for heart disease, it recognizes that oral health can be an important indicator of overall systemic health and well-being.

“Bacteria in inflamed teeth and gums may spread through the bloodstream to other parts of the body, including the heart and brain. Chronic gum inflammation may be associated with other systemic health conditions, including coronary artery disease, stroke, and type 2 diabetes,” says .

The study group consisted of 288 Asian adults, 66% of whom were men, who were being treated for AFib, all of whom were examined by a dentist before undergoing catheter ablation of AFib. Catheter ablation is a procedure that uses radiofrequency energy to destroy a small area of ​​heart tissue, causing a fast and irregular heartbeat.

This research was supported by a grant from the Japan Society for the Promotion of Science Johnson and the Johnson Medical Research Council.
