Dyslipidemia Flashcards
Lipoproteins
Chylomicrons, VLDL, LDL and HDL
- Chylomicrons & VLDL: triglyceride rich
- LDL is cholesterol rich
- HDL is protein rich
Chylomicrons
Contain large amount of lipid and very little protein
HDL
More protein and small amount of lipid (good lipid)
- Picks up extra cholesterol from tissue
- helps remove LDL preventing it from building up in arteries
Lipoproteins
Are large carriers proteins to help transport (water soluble)
Etiology
- Two types: Primary/Familial or secondary
- Primary/Familial: genetic defect that can cause increase or decrease in lipoproteins.
- Secondary: Diet, drugs, disorder, disease
ASVCD Risk
- LDL: Dominant atherogenic cholesterol, delivers cholesterol to the cells
- VLDL: Main carrier of TG to the cells
Statin Benefit Groups
- clinical ASCVD, LDL-c >190mg/dL
- Diabetes, age 40-75 with LDL-C 70-189
- Primary prevention-no ascvd or diabetes with LDL-C 70-189 mg/dL and 10 yr ASCVD risk >7.5%
Total cholesterol
measures the combination of LDL, HDL and VLDL (VLDL is a precursor of LDL)
LDL
Low density lipoproteins
- Most of the cholesterol in the blood is carried by LDL
- LDL combines with other substances clogging arteries
- High saturated fat and trans fat diets increase LDL cholesterol
LDL score
-For most people, an LDL score below 100 is healthy, but people with heart disease may need to aim lower
Total Cholesterol Score
-Score of under 200 is considered healthy
HDL score
higher the level of HDL cholesterol the better. Too little-more likely to develop heart disease
Triglycerides
- Body converts excess calories, sugar, and alcohol into triglycerides
- Causes of high triglycerides
- -Obesity
- -smoking
- -physical inactivity
- -drugs (steroids, protease inhibitors, estrogen)
- genetics
- excess alcohol
- high carb diets
Triglyceride Scores
Normal <150 mg/dL
Borderline high 150-199
High 200-499
Very high >500
Very high trigylcerides
turns first to prevention of acute pancreatitis, more likely to occur when triglycerides are >1000 mg/dL.
