Cardiovascular disease

• What are the risk factors for CVD?

  • Smoking
  • High blood pressure
  • Cholesterol
• What are high density lipoproteins?

  Remove cholesterol from tissues

  Protects against heart disease
• What are low density lipoproteins?

  Transport cholesterol to tissues

  Increases risk of heart disease
• Which is the good one, high density lipoproteins or low density lipoproteins?

  High density lipoproteins
• How does high blood pressure increase risk of CVD?

  • Artery walls become thicker, restricting blood flow
  • Arteries get eroded and burst, causing a haemorrhage
  • Heart has to pump more, making it more prone to failure
• How does diet increase risk of CVD?

  High levels of fat increase low density lipoprotein levels so increase blood cholesterol concentration
