• What are cardiovascular diseases primarily related to?

  Heart and blood vessels
• What is a key feature of cardiovascular diseases?

  They are non-communicable
• What is an example of a cardiovascular disease?

  Coronary heart disease
• What is the purpose of the coronary arteries?

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

  Fatty material builds up in coronary arteries
• 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 statins used for?

  To reduce cholesterol levels in 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 using 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 are faulty?

  The heart may have to pump harder
• What are the 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 may need to be replaced
• What is heart failure?

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

  Donated heart or heart and lungs
• What is a problem with donated hearts?

  Not enough available for all patients
• What must patients take after receiving a donated heart?

  Drugs to prevent rejection
• What is an artificial heart used for?

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

  Increased risk of blood clotting
• Why are artificial hearts not a long-term solution?

  They can only be used for a 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)
  • Donated hearts for heart failure
  • Artificial hearts as temporary solutions
• What are the advantages and disadvantages of mechanical and animal heart valves?

  Mechanical valves:

  • Last a lifetime
  • Increase risk of blood clots

  
  

  Animal valves:

  • Do not last as long
  • No need for anti-clotting drugs
