- 1. What is it?

- Cardiovascular disease is a term used to describe diseases of the heart or blood vessels.
- Coronary Heart Disease
- 2. What is it?
- CHD is when the coronary arteries that supply the blood to the muscle of the heart get blocked by layers of fatty material building up.
- This causes the arteries to become narrow, so blood flow is restricted and there's a lack of oxygen to the heart muscle - this can result in a heart attack.
- CHD is when the coronary arteries that supply the blood to the muscle of the heart get blocked by layers of fatty material building up.
- 3. What are stents? How can they treat CHD?
- Stents are tubes that are inserted inside arteries.
- They keep them open, making sure blood can pass through to the heart muscles. This keeps the persons heart beating.
- 4. Advantages of stents
- They are a way of lowering the risk of a heart attack in people with CHD.
- They are effective for a long time and the recovery time from the surgery is relatively quick.
- 5. Disadvantages of stents.
- Risk of complications during the operation and infection from the surgery.
- Risk of thrombosis - a blood clot near the stent.
- Stents are tubes that are inserted inside arteries.
- 2. What is it?
- 6. What are statins used for?
- They reduce cholesterol in the blood.
- 7. What is it and what are the problems with too much of it in our blood?
- Cholesterol is an essential lipid that your body produces and needs to function properly. Too much of it can cause health problems.

- 8. Advantages of statins
- Can reduce the risks of strokes, coronary heart disease and heart attacks.
- Can increase the amount of good cholesterol.
- 9. Disadvantages of statins
- Must be taken regularly.
- Can cause negative side effects like headaches.
- They reduce cholesterol in the blood.
- 10. What are artificial hearts and when are they fitted?
- Mechanical devices that pump blood for a person whose own heart has failed.
- 11. Advantages
- Less likely to be rejected by immune system than a donor heart. Because they're made from metals and plastics.
- 12. Disadvantages
- Surgery can lead to bleeding and infection.
- Don't work as well as natural ones.
- Blood doesn't flow through as smoothly.
- 13. When was the first one inserted into a patient?
- 1982
- 14. When are replacement heart valves fitted?
- When the heart is damaged or weakened. By heart attacks, infection or old age.
- 15. What are biological valves?
- Valves taken from humans or other mammals.
- 16. What are mechanical valves?
- Man-made valves.
- 17. Advantages and disadvantages of replacing valves
- A much less drastic procedure than a whole heart transplant. But there can still be major blood clots from the surgery.
- 15. What are biological valves?
- When the heart is damaged or weakened. By heart attacks, infection or old age.
