Oral conditions can spread beyond the mouth. In fact, research has found a direct link between periodontal (gum) disease and an increased risk for developing heart disease. Oral bacteria is capable of entering the bloodstream and spreading to the heart, which can lead to infection, inflammation, and other serious complications.
A recent study conducted by researchers from the Ewha Womans University College of Medicine and the University of Ulsan College of Medicine, Korea highlights on the impact of good oral hygiene and the decreased risk of heart disease and atrial fibrillation.
HF and AF
Before we dive into the study, let’s discuss the cardiac conditions, heart failure and atrial fibrillation. Heart failure doesn’t mean the heart isn’t working, rather that it isn’t pumping blood as well as it should be, and the heart simply can’t keep up with the workload. This causes the body to lack the oxygen it needs to perform at full capacity. Heart failure is an incurable condition that can be managed with medications and a healthy lifestyle.
Atrial fibrillation is an irregular heartbeat (arrhythmia) that can lead to cardiac complications such as blood clots, heart failure, and stroke. Sometimes asymptomatic, AF can cause dizziness, fast heartbeat, fatigue, and heart palpitations. It can be treated with medications and sometimes surgical procedures.
The Study
Published in the European Journal of Preventive Cardiology, the study investigated the association of oral hygiene indicators with risk of atrial fibrillation and heart failure. It followed 161,286 Koreans ages 40-79 with nohistory of atrial fibrillation, heart failure, or cardiac valvular diseases. Between 2003-2004, the participants underwent a routine medical examination that included oral hygiene indicators, presence of periodontal disease, number of tooth brushings, any reasons of dental visit, professional dental cleaning, and number of missing teeth.
The participants were medically re-evaluated after 10.5 years. The findings concluded that 4,911 (3.0%) participants developed atrial fibrillation and 7,971 (4.9%) developed heart failure. Those who brushed their teeth three or more times a day had a 10% lower risk of atrial fibrillation and a 12.5% lower risk of heart failure during the 10.5-year time period.
The study unveiled the possibility that frequent brushing can reduce bacteria in the subgingival biofilm (bacteria between teeth and gums), which in turn, prevents it from seeping into the bloodstream.
The Takeaway
The study from the Ewha Womans University College of Medicine and the University of Ulsan College of Medicine, Korea raises awareness for both oral and heart health. It should encourage proper oral health care, especially for those with any cardiac conditions.
