• Atherosclerosis

5
Draw a picture depicting what atherosclerosis
looks like.

Coronary Artery Disease (Heart Disease)

• Greatest killer of all CV diseases! Leads to
  heart attack!
• How a heart attack happens
• 1. In order to function, the heart has to have
  oxygen, thus it needs blood!
• 2. Blood (and O2) are delivered to the heart via
  coronary arteries
• 3. When these arteries become clogged, O2 cannot
  reach the heart and a heart attack may occur!

Congestive Heart Failure

• Your heart is a big muscle (cardiac muscle)
• CHF occurs when your muscle becomes overworked,
  and lacks strength

14
Congestive Heart Failure

• Heart is not strong enough to pump blood to the
  rest of the body.
• Blood pools and causes body/heart tissues to
  swell! This causes the congestion!

• Think of it like this
• A sump pump! If that pump doesnt get the water
  out from your basement, it will pool, creating a
  mess!
