  • CVD Factors
    • Lifestyle
      • Diet
        • High in saturated fat increases risk
          • Increases blood cholesterol
            • Increases atheroma formation
              • Forming blood clots, and leads to heart attacks/strokes/DVT
      • HBP
        • Risk of damage to artery walls
          • Increases atheroma formation risk
        • Can be caused by:
          • Excessive alcohol consumption
          • Stress
          • Diet
      • Smoking
        • Carbon monoxide in smoke combines with haemoglobin
          • Haemoglobin is a protein that carries oxygen in blood
          • Reduces amount of oxygen to be transported and oxygen available to tissues
            • Heart muscle doesn't get enough oxygen = heart attack
            • Brain doesn't get enough oxygen = stroke
        • Nicotine causes sticky platelets, increasing thrombosis formation
        • Decreases amount of antioxidants in the blood
          • Antioxidants protect cells from damage
          • Fewer antioxidant means an increase in damage to artery walls, increase risk of CVD
      • Inactivity
        • Lack of exercise, increases blood pressure, leading to CVD
    • Uncontrollable factors
      • Genetics
        • Some people inherit specific alleles which make them more likely to have HBP or HBC, therefore more likely to suffer from CVD
      • Age
        • Increased risk with age
          • Plaque builds up slowly over time, eventually can lead to CVD
      • Gender
        • Male
          • 3x more likely to suffer than pre-menopausal women
            • Due to different hormone levels, i.e oestrogen
              • Lower levels in men can lead to higher levels of blood cholesterol
        • Female
          • Oestrogen levels higher, increased HDL
