What causes a blocked artery?
Atherosclerosis is the buildup of fatty deposits on the inside of the arteries.  They become narrow and reduce the blood flow to the heart (like a clogged drain).

Where does the artherosclerosis come from?
Cholesterol is a necessary component of the human cell; but, over time, cholesterol in the blood can become deposited on the inside walls of the arteries.  This seems to happen faster in people who:

• Smoke
• Have high blood pressure
• Eat high fat, high cholesterol foods, or have high cholesterol
• Are overweight
• Have a lot of tension or stress
• Do not exercise regularly
• Have diabetes and/or family members with a history of atherosclerosis
