  • Cardiovascular Disease
    • Coronary Heart Disease is a disease of the coronary arteries
      • Supply the heart with blood
      • Happens when layers of fatty material build up in the coronary arteries causing them to become narrow
        • Reduces blood flow to the heart muscle
          • Less oxygen can get to the heart muscle resulting in a heart attack
    • Stents
      • Tubes that are put inside coronary arteries by surgery, keeping the artieries open
      • Allows blood to reach the hears muscles and reduces the risk of a heart attack
      • Effective for a long time, recovery time from the surgery is quick
      • Risks; - having a  heart attack during the operation or getting an infection after surgery. A blood clot can be developed near the stent too
    • Statins
      • A drug taken that reduced the cholesterol in the blood
        • Cholesterol - a lipid that your body needs, but too much can cause fatty deposits to form inside arteries
      • They slow down the rate of fatty deposits forming
      • Advantages; - reduce the risk of strokes, coronary heart disease and heart attacks
      • Disadvantages; - The drug has to be taken regularly over a long time - person could forget to take them. Can cause unwanted side effects - headaches. The effect isn't instant - takes a while for it to start working
