Combined CVD risk factors effect
Combined CVD risk factors effect
Multiplicative, not additive
Smokers' CVD risk vs non-smokers
Smokers' CVD risk vs non-smokers
2-6 times more likely
Carbon monoxide binds to haemoglobin forming
Carbon monoxide binds to haemoglobin forming
Carboxyhaemoglobin
Nicotine's effect on heart rate & blood pressure
Nicotine's effect on heart rate & blood pressure
Stimulates adrenaline, increases both
High blood pressure effect on heart
High blood pressure effect on heart
Heart works harder, more susceptible to failure
HDL cholesterol function
HDL cholesterol function
Removes cholesterol from tissues ('good' cholesterol)
LDL cholesterol function
LDL cholesterol function
Transports cholesterol to tissues, forms atheroma ('bad')
High salt intake effect
High salt intake effect
Raises blood pressure
High saturated fat effect
High saturated fat effect
Increases LDL cholesterol levels
Risk factors guarantee CVD?
Risk factors guarantee CVD?
No, increase probability but don't guarantee disease
