Coronary heart disease occurs when fatty proteins and a substance called plaque build up on the walls of your arteries. This causes the arteries to narrow, constricting blood flow. Oxygen is restricted from traveling to the heart which results in shortness of breath, chest pain, and even heart attack.
The link between periodontal disease and heart disease is so apparent that patients with oral conditions are nearly twice as likely to suffer from coronary artery disease than those with healthy mouths. Periodontal disease has also been proven to exacerbate existing heart conditions. Additionally, patients with periodontal disease have been known to be more susceptible to strokes. A stroke occurs when the blood flow to the brain is suddenly stopped. This may occur, for example, when a blood clot prevents blood from reaching the brain.
One of the causes of the connection between periodontal disease and heart disease is oral bacteria entering the bloodstream. There are many strands of periodontal bacteria. Some strands enter the bloodstream and attach to the fatty plaques in the coronary arteries. This attachment leads to clot formation and increased risk to a variety of issues including heart attack.
Inflammation caused by periodontal disease creates an increase in white blood cells and C-reactive proteins (CRP). CRP is a protein that has long-been associated with heart disease. When levels are increased in the body, it amplifies the body’s natural inflammatory response. Bacteria from periodontal disease may enter the bloodstream, causing the liver to produce extra CRP, which then leads to inflamed arteries and possibly blood clots. Inflamed arteries can lead to blockage, which can cause heart attacks or strokes.
Coronary heart disease is the leading cause of death in the United States for both men and women. Enacting positive oral hygiene practices and obtaining treatment for periodontal problems can help prevent the risk of developing this unfortunate condition.
