The document discusses coronary artery disease (CAD), which is the narrowing of the arteries that supply blood to the heart muscle. CAD is a common heart disease caused by factors such as fatty foods, smoking, high blood pressure, and stress. As the arteries narrow, less blood flows to the heart muscle. During exercise, there may not be enough increased blood flow, causing chest pain. In severe cases, parts of the heart muscle may die from lack of oxygen, resulting in a heart attack. The document recommends preventing CAD by maintaining a healthy lifestyle without smoking or high blood pressure, and treating existing conditions like diabetes. For those who develop CAD, treatment may involve procedures to open blocked arteries.

By Megnot Tesfaye

2. What is the heart?
• The heart is the pump of the circulatory
system. It pumps blood to the rest of your
body. Your heart is made out of heart muscle.
Your heart muscle gets its blood from your
coronary arteries.
• Coronary arteries are small blood vessels.
Each area of heart muscle is supplied by a
particular branch of your coronary arteries.

3. What is CAD ?
• CAD is narrowing of the arteries to the heart
muscle and problems resulting from this.
• CAD is a very common heart disease in Australia.

4. What causes CAD?
Causes of CAD include:
• fatty foods and high cholesterol
• smoking cigarettes
• high blood pressure
• stress

5. What happens when you get CAD?
• Less blood gets to your heart muscle. When
you exercise the blood flow to your heart
muscle cannot increase enough and you get
chest pain.
• If you get very little blood flow to your heart
muscle, areas of muscle may die [heart
attack].

7. How can you avoid CAD?
You can help to prevent CAD by:
• eating healthy foods
• doing exercise
• Not smoking cigarettes
• Treating high blood pressure
• Maintaining good health e.g. treating diabetes

8. What can you do after you got CAD ?
• Avoid risk factors.
• Repair coronary arteries e.g. prop open
coronary arteries [stent]
• Bypass blocked areas of coronary arteries
[bypass grafts]
