Lipids Flashcards
what is the good role of cholesterol
one example of bad
sex hormones
bile acids
energy source
cell membranes
bad= vascular sclerotic disease
what do you get with a lipid profile test
total cholesterol
LDL-c (calculated)
HDL
TG
why is cholesterol checked
assess for hyperlipidemia
identify risk for atherosclerotic cardiovascular disease
what is the leading cause of death in US
cardiovascular disease
in which group of ppl is increased chol a larger factor in causing death?
those with CHD or those without
those without coronary heart disease have a higher correlation to death and high cholesterol
where do LDLs deliver chol
HDL?
LDL- to body cells
HDL to liver for excretion
LDL-c
low denisity lipoprotein (calculated)
HDL
high density lipoprotein
VLDL
very low density lipoprotein
TRG
triglycerides
what are indications to run lipid panel
determining risk of cardiovascular disease
evaluate respones to dietary / drug therapy to treat hypercholesterolemia
investigate hypercholesterolemia for pts with fam history of cardiovascular disease
why should you get a fasting blood draw for lipid panel
because although LDL and HDL do not differ much, high difference in TGs with fasting vs not fasting
when do we screen men for lipid disorders
men with increased risk of coronary heart disease
men 35 years and older
increased risk= 20-35
when do we screen women for lipid disorders
women with increased risk of coronary heart disease
45 years and older
increased risk= 20-45
high TG levels make what innacurate
calculated LDL measures are innacurate
HDL high levels vs low levels
high= protective
low= increaed risk for CAD
what elevates HDL
fish oils
exercise
what do statin drugs do to LDL or HDL
LDL= decrease with statin
HDL= increase with statin
this is great drug
how should you think of TG
bloodstream fat
does high chol mean pt has heart disease
no
this would just help determine risk for heart diseaes
what should pt do before taking lipid panel
no alcohol 24 hours
no durgs that alter chol within 12 hours
dont lay down for 20 mins before test
fasting 12 hours before
what causes increase in total cholesterol
alcholism renal failure HIGH FAT DIET OBESITY ischemic heart disease
reasons for decreased cholesterol
burns
COPD
malabsorption
what does the cholesterol ration tell oyu
amount of good chol compared to bad
optimal is 3.5 : 1
