Coronary Heart Disease.

AQA A Level Physical Education. 

For questions on CHD. 

  • This will aid with questions on the prevention of CHD and how it can be prevented through a healthy active lifestyle.

Maybe practise answering the following questions after you have revised. 

  • Describe the characteristics of CHD.
  • Explain how an active healthy lifestyle can help to prevent CHD.
  • Define CHD.
  • How might a healthy diet prevent CHD?

  • Coronary Heart Disease
    • Definition
      • The failure of the coronary arteries to supply enough oxygen to myocardium
      • Fatty materials deposited in coronary arteries
    • What causes CHD?
      • Smoking
        • Increases carbon monoxide - more strain on the heart, increases damage of coronary arteries
      • Obesity
        • Inactive lifestyle
      • Hypertension(High blood pressure
      • High cholesterol
        • High amounts of LDL
      • Diabetes
    • Symptoms of CHD
      • Angina
        • Partial blockage of coronary artery
      • Heart attacks
        • complete blockage of oxygen supply to myocardium
      • Arteriosclerosis
        • Walls of coronary arteries become less elastic
      • Atherosclerosis
        • fatty deposits on walls of coronary arteries, leads to narrowing of lumen,
          • leads to stroke or heart attack
    • Prevention
      • Healthy Active lifestyle
        • Adults - aerobic activity, 30 mins, 3 times a week
          • For example cycling, running or rowing.
        • Increases HDLs, to carry away LDLs (cholesterol
          • Lower risk of hypertension (high blood pressure)
          • Lowers the risk of heart attack.
        • Lower risk of angina
          • Because coronary circulation is improved
      • Healthy diet
        • Low fat / low cholesterol
          • Prevent arteriosclerosis and atherosclerosis
          • Increase HDLs in blood
        • Stop smoking
        • Reduce alcohol intake
        • Lower salt intake
