Many people do not realize they are at risk for having a stroke until it’s too late. Make sure you know the signs, symptoms and ways to prevent your becoming a victim of stroke due to carotid artery disease.
What is Carotid Artery Disease?
Oxygen-rich blood from your heart is carried to other part of your body by
your arteries. The arteries that supply blood to your brain are called carotid
arteries. They are located on either side of your neck. You can actually feel
the pulse of these arteries on your lower neck on each side of your windpipe.
If these arteries cannot do their job effectively, it can affect the front part
of your brain. This area is responsible for your ability to think, speak, move,
and for your personality.
Carotid artery disease occurs when something causes these arteries to be
ineffective. If these arteries develop a build up of fat or cholesterol
deposits, blood flow is inhibited or stopped, and stroke can occur. The build
up of these deposits is known as ‘plaque.’ Your arteries start out as being smooth
and unobstructed on the inside. As plaque builds up, the arteries begin to
harden. Carotid artery disease takes place when the plaque has increased enough
to cause a blockage.
What is a Stroke?
Stroke is the third leading cause of death in the United
States, following heart disease and cancer.
It is a type of cardiovascular disease.
Your brain needs oxygen and nutrients to survive. These are provided by
blood flow. When your brain cells are deprived of these, a stroke occurs. If
the blood flow is cut off for more than 3-6 hours, permanent damage can occur.
Are YOU at Risk?
Risk factors for stroke are similar to those of heart disease. They include:
Smokers
Diabetics
People with high cholesterol
People with high blood pressure
People with a family history
of carotid artery disease
People with a family history
of CAD (coronary artery disease)
