Disease

• Cardiovascular Disease


  Diseases of the heart or blood vessels
• Stents Keep Arteries Open

  1. Arteries that supply blood to the heart get blocked by fatty material

  2. Arteries become narrowed, restricting blood flow to the heart muscle

  3. Stents are inserted into the arteries to keep them open, allowing blood to flow to the heart
• Stents


  • Keep arteries open, allowing blood to flow to the heart muscle
• Stents are a way of reducing the risk of heart attack in people with coronary heart disease
• Stents are inserted into blocked arteries

  This keeps the person's heart beating and the person alive
• There are risks of complications during the stent operation (e.g. heart attack) and a risk of infection from the surgery
• There is also a risk of patients developing blood clots near the stent, called thrombosis
• Statins


  Drugs that can reduce the amount of 'bad' (LDL) cholesterol in the blood
• Having too much 'bad' cholesterol in the bloodstream can cause fatty deposits to form inside arteries, leading to coronary heart disease
• Statins can reduce the rate of fatty deposits forming
• Advantages of statins


  • Reduce risk of strokes, coronary heart disease and heart attacks
  • Increase amount of 'good' (HDL) cholesterol in bloodstream
  • May help prevent some other diseases
• Disadvantages of statins


  • Long-term drug that must be taken regularly, risk of forgetting
  • Can cause negative side effects like headaches, kidney failure, liver damage, memory loss
  • Effect takes time to kick in
• Unlike stents and statins, using CGP books only has advantages
