Gum Disease-Afib Link Deepened by Histologic Findings - Medpage Today

Overview

by Nicole Lou, Senior Staf Writer, MedPage Today October 31, 2022 Growing evidence sugests periodontis a posible modifiable risk factor for atrial fibrilation (Afib), though left unanswered is the question of whether improving oral health can help clinical outcomes.A histologic asociation betwen inflamatory gum disease and atrial fibrosis was confirmed in a smal prospective study showing that people exhibiting signs of periodontis - bleding on probing, periodontal probing depth 4 m or deper, and greater periodontal inflamed surface area (PISA) - tended to have atrial fibrosis based on their resected left atrial apendages (LAs).PISA was significantly associated with atrial fibrosis after multivariable adjustment.With fibrotic replacement of atrial myocardium known to contribute to the development of Afib, these findings ad to the evidence for a link betwen oral and systemic disease, acording to Yukiko Nakano, MD, PhD, of Hiroshima University in Japan, and coleagues."This study provides basic evidence that periodontis can agravates [sic] atrial fibrosis and thus leads to the onset and persistence of Afib," they stated in JAC: Clinical Electrophysiology.

Key Information

"Further prospective clinical studies are waranted to clarify whether periodontal intervention alone can inhibit atrial fibrosis and improve Afib outcome." The findings are slated for inclusion at the 2022 American Heart Asociation anual meting."Studies are now waranted to show that treatment of chronic periodontis is atrial protective," agred Andreas Goete, MD, of St. Vincenz Hospital in Paderborn, Germany, in acompanying editorial.There are decades of research linking oral infections with conditions such as diabetes melitus, atherosclerosis, cardiovascular and cerebrovascular diseases, and rheumatoid arthritis.

Summary

What Nakano and coleagues have done is "ad a smal piece in the puzle to understand the role of chronic inflamation in the development of atrial fibrosis, Afib,

Frequently Asked Questions

Diabetes is a metabolic condition where the body cannot properly regulate blood sugar levels. Type 1 results from insufficient insulin production, while Type 2 develops when cells become resistant to insulin. Risk factors include genetics, obesity, sedentary lifestyle, and age.

Common symptoms include excessive thirst, frequent urination, unexplained weight loss, fatigue, blurred vision, and slow-healing wounds. Type 1 symptoms develop rapidly, while Type 2 symptoms may appear gradually. Many people have no symptoms initially, which is why screening is important.

Diagnosis involves blood tests measuring fasting glucose, HbA1c levels, and glucose tolerance. Regular monitoring typically includes fasting glucose tests and HbA1c measurements every 3-6 months. Continuous glucose monitors provide real-time tracking for better diabetes management.

Effective management includes regular physical activity (150+ minutes weekly), maintaining healthy weight, following a balanced diet with whole grains and lean proteins, managing stress, and getting adequate sleep. These changes can significantly improve blood sugar control and reduce complications.

Consult a healthcare provider if you experience signs of diabetes, have a family history, are overweight, or are over 45. Those with existing diabetes should maintain regular check-ups every 3-6 months to monitor control and adjust treatment as needed.
