• What is the function of the coronary arteries?

  To provide oxygen to heart muscle cells
• What happens to the coronary arteries in coronary heart disease?

• What is the effect of narrowed coronary arteries?

  Reduced blood flow and oxygen to the heart
• What can extreme cases of coronary heart disease lead to?

  A heart attack
• What are two common treatments for coronary heart disease?

  Statins and stents
• What do statins do?

  Reduce cholesterol levels in the blood
• What is an advantage of statins?

  They reduce the risk of coronary heart disease
• What is a disadvantage of statins?

  They can cause liver problems
• What is a stent used for?

  To keep a coronary artery open
• What is an advantage of inserting a stent?

  Normal blood flow through the artery
• What is a limitation of a stent?

  It does not treat underlying causes
• What can happen when heart valves do not function properly?

  The heart may enlarge
• What are two types of heart valves that can be used for replacement?

  Mechanical valves and animal valves
• What is a benefit of mechanical valves?

  They can last a lifetime
• What is a risk associated with mechanical valves?

  Increased risk of blood clots
• What is a disadvantage of animal valves?

  They do not last as long
• What is heart failure?

  The heart cannot pump enough blood
• What is a common treatment for heart failure?

  Donated heart or heart and lungs
• What are two problems with heart transplants?

  A temporary solution for heart failure
• What is a risk associated with artificial hearts?

  Increased risk of blood clotting
• How long can artificial hearts be used?

  For a relatively short time
• What are the methods of treating cardiovascular diseases?

  • Statins to reduce cholesterol
  • Stents to keep arteries open
  • Heart valve replacements (mechanical or animal)
  • Heart transplants or artificial hearts
• What are the advantages and disadvantages of statins?

  Advantages:

  Disadvantages:

  • Can cause liver problems
• What are the advantages and disadvantages of stents?

  Advantages:

  • Allow normal blood flow

  Advantages:

  • Do not require anti-clotting drugs

  Disadvantages:

  • Do not last as long
