- Coronary Heart Disease Risk Factors
- Smoking
- Carbon monoxide irreversibly combines with haemoglobin
- Reduces oxygen-carrying capability of the blood
- Heart has to pump harder to supply tissues = high blood pressure
- Reduces oxygen-carrying capability of the blood
- Nicotine stimulates adrenaline production
- Increases heart rate = high blood pressure
- Nicotine makes platelets more 'sticky' =higher thrombosis risk
- Carbon monoxide irreversibly combines with haemoglobin
- High Blood Pressure
- Heart must pump harder to pump blood into arteries = heart more likely to fail
- Increased aneurysm chance
- Artery walls thicken to resist pressure = restricted blood flow
- Damages lining of the arteries
- High salt diet
- Prolonged stress
- Lack of exercise
- Blood Cholesterol
- Low-density lipoproteins infiltrate artery walls = cause atheromas
- High saturated fat diet
- Smoking
