Dyslipidemia Flashcards
Dyslipidemia consists of one or all 3 of the following:
increased LDL, decreased HDL, increased triglycerides
What are the 2 sources of cholesterol in the body
exogenous (dietary) and endogenous (genetics/hereditary) - main source of cholesterol
Excess LDL becomes cytotoxic and initiates:
atherosclerosis and CV disease
LDL is known as:
HDL is known as:
bad or lousy cholesterol - transports cholesterol to peripheral cells
good or helper cholesterol - transports cholesterol to liver and kidneys for removal from body
Goal of LDL:
Goal of HDL:
Goal of total chol:
Goal of triglycerides:
< 100
40-60
< 200
< 150
Primary cause of hyperlipidemia:
Secondary causes:
genetics
diet, DM, hypothyroidism, CRF, alcoholism, medications
Treatment decisions for hyperlipidemia are based on what 2 things?
1) CHD risk assessment, 2) Risk factor status
CHD risk factors include:
smoking, HTN, low HDL cholesterol (< 40), family hx of CHD, age (men > 45, women > 55)
CHD risk:
Multiple (2+) risk factors:
0-1 risk factor:
< 100
< 130
< 160
Therapeutic lifestyle changes is the cornerstone in LDL-lowering therapy include:
TLC diet, stay away from saturated fats like whole fat dairy products, fast food, donuts/cookies, processed meats (bologna, salami, pepperoni)
plants sterols and fiber lower LDL
wt reduction, increased activity
CAGE questionnaire includes:
C - cheese (diary fats)
A - animal fats (hamburger, ground meat, bologna, salami, sausage, fried foods)
G - got it away from home (fast food)
E - eat extra amts of (candy, pastries, pies, doughnuts, cookies
Drug therapy for hyperlipidemia:
1) start on statin (HMG CoA Reductase Inhibitors)
2) consider higher dose of statin or add a bile acid sequestrant or nicotinic acid
- monitor response every 6 weeks
When increasing the dose of a statin, you also increase risk for s/e:
rhabdomyolysis (breakdown of muscle fibers that can be toxic to kidneys, causing renal failure)
For hyperlipidemia, always use therapeutic lifestyle changes first, like ___ and ___.
diet, exercise
For elevated LDL, use a ___. ___ is the gold standard.
statin, crestor
For elevated triglycerides, use a ___, like ___ or ___.
fibrate/fibric acid, tricor or cholestyramine
For decreased HDL levels, use a ___, like ___.
nicotinic acid, niacin
Which level is the primary target of cholesterol lowering therapy? First priority to to decrease ___ level, unless triglycerides are > ___, then treat triglycerides FIRST.
LDL, LDL, 500
Framingham risk scoring adds up totals of:
age, total cholesterol, smoking status, HDL level, syst. b/p
A lipoprotein analysis/fasting lipid profile includes drawing:
total cholesterol, LDL, HDL, and total triglycerides
Drug classifications for the tx of dyslipidemia include: ___. The purpose of all tx’s is to decrease ___ level and raise ___ level.
HMG CoA reductase inhibitors (statins), bile acid sequestrants, nicotinic acid, fibric acids, LDL, HDL
HMC CoA reductase inhibitors bind and inhibit HMG CoA reductase to decrease the amount of ___ cholesterol.
endogenous
All tx’s for dyslipidemia may cause ___ and eventually lead to ___.
myopathy, rhabdomyolysis
Statins include: ___.
They work best at what time of day?
lovastatin (mevacor), pravastatin (pravachol), simvastatin (zocor), atorvastatin (lipitor), rosuvastatin (crestor)
evening/bedtime
