Factors that increase the risk of CVD (inc CHD)
Mind map with the risk factors that increase the risk of gaining CVD (and CHD). I got my revision information from, 'CGP AS-Level Biology, the Revision guide'. The ISBN is: 978 1 84762 121 4
Hope my mind map helps :)

- Factors that increase the risk of CVD
- DIET
- HIGH BLOOD PRESSURE
- Increase risk of damage to the walls - increase risk of atheroma formation
- Factors that increase blood pressure: excessive alcohol consumption, stress, unhealthy diet
- SMOKING
- Carbon monoxide combines with haemoglobin in the blood, reducing the amount of oxygen going to the tissues
- If heart does not recieve enough oxygen - heart attack
- If brain does not recieve enough oxygen - stroke
- Nictotine in cigarettes makes platelets sticky - increases chance of blood clots (thrombosis)
- Smoking reduces the amount of antioxidants in the blood - these protect the cells from damage
- Fewer antioxidants mean cell damage in arteries is more likely to occur - atheroma formation
- INACTIVITY
- Lack of exercise increases blood pressure - increase risk of damage to the artery walls - atheroma
- GENETICS
- Some people imherit perticular allels that cause high blood pressure/ high blood cholesterol
- AGE
- The risk of developing CVD increases with age
- GENDER
- Men are 3x more likley to develop CVD than pre-menopausal women
