Heart
Disease, Stroke and Periodontal Disease Connected
Heart Disease
Several theories exist to explain the link between periodontal
disease and heart disease. One theory is that oral bacteria
can affect the heart when they enter the blood stream, attaching
to fatty plaques in the coronary arteries (heart blood vessels)
and contributing to clot formation. Coronary artery disease
is characterized by a thickening of the walls of the coronary
arteries due to the buildup of fatty proteins. Blood clots
can obstruct normal blood flow, restricting the amount of
nutrients and oxygen required for the heart to function
properly. This may lead to heart attacks.
Another possibility is that the chronic inflammation caused
by periodontal disease increases plaque buildup, which may
contribute to thickening of the walls of the arteries.
Researchers have found that people with periodontal disease
are almost twice as likely to suffer from coronary artery
disease as those without periodontal disease.
Periodontal disease can also exacerbate existing heart
conditions. Patients at risk for infective endocarditis
may require antibiotics prior to dental procedures. Dr.
Peterson and your cardiologist will be able to determine
if your heart condition requires use of antibiotics prior
to dental procedures.
Stroke
Additional studies have pointed to a relationship between
periodontal disease and stroke. In one study that looked
at the causal relationship of oral infection as a risk factor
for stroke, people diagnosed with acute cerebrovascular
ischemia were found more likely to have an oral infection
when compared to those in the control group.
