Dyslipidemia Flashcards
(113 cards)
cholesterol is an important component of healthy cells and tissues including the brain. It is a component of cell walls and a precursor in hormone synthesis. Also is used in the production of bile acids. It is when cholesterol levels are in elevated states that put us at risk for ___________
cardiovascular and other disease
Bile acids are needed to __________. Bile acids are produced __________ and then travel through the bile ducts into __________. This is where bile acids are converted to __________ which are then recycled and returned to _______
absorb lipids, including fat-soluble vitamins.
in the liver.
the small intestine
bile salts
the liver
The process enterohepatic recycling involves the __________ and the __________
gut (enteric system)
liver (hepatic)
Atherosclerosis: is _____
the formation of plaque from the buildup of fats, cholesterol and other substances on the inner walls of arteries
Atherosclerosis although asymptomatic, leads to ______________, which includes ___________.
Different types of cholesterol either __________from or contribute to ASCVD risk
(ASCVD) atherosclerotic cardiovascular disease
myocardial infarction, stroke/transient ischemic attacks, angina and peripheral arterial disease.
protect
Cholesterol in the body can be decreased by:
1)
2)
3)
reducing the formation (like with statins)
blocking absorption (ezetimibe)
blocking enterohepatic recirculation of bile salts (bile acid sequestrants like colesevelam)
Lipids in the body are transported via _________. they are not transported by themselves. These types of lipoproteins are what we call are types of ________
lipid proteins
cholesterol or types of lipids
LDL
what level is desirable?
what level is very high?
In someone with diabetes or ASCVD we want to target a lower level. what level is desirable in this case?
Low-density lipoprotein “bad cholesterol”
we want low
- < 100mg/dL is desirable
- > or = 190mg/dL is very high
In someone with diabetes or ASCVD we want to target a lower level.
We want a level < 70 mg/dL
HDL
what level is normal in men?
what level is normal in women?
High density lipoprotein “good cholesterol”
we want high
> 40mg/dL is normal in men
50mg/dL is normal in women
VLDL
Very-low density lipoproteins
-these carry TG
Total cholesterol:
LDL + HDL + VLDL + TG
Non-HDL:
what level is desirable?
total cholesterol - HDL
< 130 mg/dL id desirable
elevations in cholesterol increase risk for _________________ due to fat accumulation in the arteries.
atherogenic disease (tending to promote the formation of fatty plaques in the arteries)
Dyslipidemia:
abnormality in lipoprotein levels
Primary (or familial) hypercholesterolemia:
inherited (genetic defect), severe cholesterol elevations
heterozygous familial hypercholesterolemia (HeFH)
homozygous familial hypercholesterolemia (HoFH)
Secondary (or acquired) dyslipidemia:
“what we normally are thinking of, things that can cause high levels of fat in the body”
happens from
-Diet
-Diseases like obesity, hypothyroidism, nephrotic syndrome, biliary obstruction
-Drugs
Key Drugs that increase cholesterol: they can raise LDL AND (TG)
triglycerides
diuretics
efavirenz
steroids
immunosuppressants (cyclosporine & tacrolimus)
atypical antipsychotics
protease inhibitors
retinoids
Key drugs that increase LDL only:
Fish Oils (except Vascepa)
fibric acids
SGLT2 inhibitors
thiazolidinediones
anabolic steroids
fibrates
progestins
Key drugs that increase TG only:
IV lipid emulsions
Propofol
Bile acid sequestrants
alcohol
estrogen
tamoxifen
clevidipine
beta-blockers
Lipid panels are taken after a _________. If the LDL isn’t reported, it can be calculated using _____________.
We cannot use this equation when _______________
9-12 hour fast
Friedewald equation: LDL = TC - HDL - (TG/5)
TGs > 400mg/dL
when should medications be considered when just looking at a patients LDL level?
if the LDL is > or equal to 190 mg/dL, then medications should be considered in a patient.
when triglyceride levels hit ____________, that is when we are worried about starting treatment for triglyceridemia and are worried about causing _____________
> or equal to 500 mg/dL this is very high
pancreatitis, if we do not get triglycerides down.
Non-drug treatment for dyslipidemia includes:
Diet: personalized diet to individual patient, to maintain a healthy weight (BMI 18.5-24.9 kg/m2)
-eating vegetables, fruits, whole grains, low fat dairy, poultry, fish, legumes, nuts
-limit sugared beverages, sweets
-Aim for 5-6% calories from saturated fat, limit trans fat
Exercise: moderate-to-vigorous physical exercise 3-4 x/week lasting 40 minutes/session
Avoid tobacco products and limit alcohol consumption.
What are natural products that may lower cholesterol levels?
