Risk Factors Flashcards
what do saturated fats do?
increase HDL cholesterol but increase LDL concentration more
-may also reduce activity of LDL receptors so LDLs not removed
Correlation between saturated fats and CVD
increased saturated fats, increased risk of CVD
What does CO do in cigarettes?
binds to haemoglobin and reduce oxygen supple so bpm increase as more oxygen needed
what does nicotine do in cigarettes
stimulated adrenaline- increases heart rate and constricts arteries so higher blood pressure too
what do other chemicals in cigarettes do?
can damage lining of arteries and trigger atherosclerosis
correlation between CVD and smoking
smoking= increased CVD risk
correlation between inactivity and CVD
inactivity=increased risk of CVD
what does exercise/activity do to reduce risk of CVD
reduces weight and raises HDL levels without affecting LDL levels
Which is which HDL and LDL good or bad?
HDL=good LDL=bad
correlation between coffee and CVD
immoderate amount=higher risk of CVD
What is arguable about coffee though?
moderate amounts can= health benefits
how is heredity linked to risk
certain genes can increase individuals susceptibility to disease (not directly cause disease)
what are the risks of a high salt diet?
-more water retained by kidney
-higher fluid levels in blood can result in elevated bp
links between stress and risk of CVD (2)
CHD linked to poor management of stress
-in stressful situations- adrenaline released
-stress can lead to high alcohol, overeating, poor diet
what does adrenaline do
-increase heart rate
-constrict arteries so blood pressure increases
