Cardiovascular

• What is cardiovascular disease?

  It is a general term for diseases of the cardiovascular system, including the heart and blood vessels.
• What are some examples of cardiovascular diseases?

  Examples include coronary heart disease, heart attacks, faulty heart valves, and heart failure.
• What is the main focus of the video on cardiovascular diseases?

  • Overview of cardiovascular diseases
  • Focus on treatments such as:
  • Stents
  • Statins
  • Replacement valves
  • Replacement hearts
• What happens in coronary heart disease?

  The coronary arteries become blocked by fatty material, narrowing the lumen and reducing blood flow.
• Why is reduced blood flow in coronary heart disease problematic?

  It means less oxygen reaches the heart muscle, which can strain the heart and lead to a heart attack.
• What are the two main treatments for coronary heart disease?

  • Stents: Expandable tubes placed in arteries to keep them open.
  • Statins: Medications that alter cholesterol levels in the bloodstream.
• What is a stent?

  A stent is an expandable tube placed inside arteries to hold them open for blood flow.
• What are the benefits of using stents?

  Stent surgery is relatively quick and effective for a long time.
• What are the risks associated with stent surgery?

  Risks include heart attack, infection, and thrombosis near the stent.
• What are statins?

  Statins are medications that alter cholesterol balance in the bloodstream.
• What types of cholesterol do statins affect?

  Statins decrease bad LDL cholesterol and increase good HDL cholesterol.
• What is the downside of taking statins?

  They must be taken regularly for years and can cause side effects like headaches and kidney failure.
• What can cause heart valves to become damaged or weakened?

  Heart valves can be damaged by aging, heart attacks, or infections.
• What is the role of heart valves?

  Heart valves allow blood to flow in one direction only.
• What are the two main problems that can occur with heart valves?

  Problems include stiff valves that don't open fully and valves that don't close properly, causing backflow.
• How can faulty heart valves be fixed?

  • Replace with biological valves (from humans or pigs)
  • Replace with mechanical valves
  • Both require surgery and carry risks of blood clots
• What is heart failure?

  Heart failure occurs when the heart cannot pump blood effectively around the body.
• What is the only proper treatment for severe heart failure?

  The only proper treatment is a heart transplant.
• What types of hearts can be used for transplants?

  • Biological hearts from human donors
  • Artificial hearts (temporary fix)
  • Cannot use pig or cow hearts
• What is a potential issue with heart transplants?

  The body may reject the donor heart as foreign due to the immune response.
• What is a challenge associated with heart and lung transplants?

  It is hard to find donor hearts and lungs, and the surgery is complicated.
