Flashcards in Lipid Disorders Deck (16):
1

What is the single largest killer of men and women in the U.S.?

- CHD

2

What is the interrelation between atherosclerosis and insulin resistance?

- HTN
- obesity
- hyperinsulinemia
- DM
- hypertriglyceridemia
- high LDL
- low HDL
- hypercoagulability

3

What is metabolic syndrome according to the NCEP ATP III?

- if three or more of the following five criteria are met:
1. WAIST CIRCUMFERENCE over 40 inches (men) or 35 inches (women)
2. BP over 130/85 mmHg
3. fasting triglyceride (TG) level over 150 mg/dl
4. FASTING HDL cholesterol level less than 40 mg/dl (men) or 50 mg/dl (women)
5. FASTING GLUCOSE over 110 mg/dl.
*aka metabolic syndrome= a group of risk factors that raise your risk for heart disease, diabetes, and stroke.

4

What are some genetic lipoprotein disorders?

- familial combined hyperlipidemia
- familial hypercholesterolemia
- familial dysbetalipoproteinemia= accumulation of remnants of VLDL.
- hyperchylomicronemia

5

**** What are our targets for lipids in T2DM?

- HDL= greater than 40 (men) or greater than 50 (women).
- LDL= less than 100
- TG= less than 150

6

What is non-HDL cholesterol and what is its significance?

total cholesterol - HDL
- consists of ApoB containing lipoproteins (aka VLDL, IDL and LDL) and other atherogenic lipoproteins.

7

What is the goal of Non-HDL cholesterol?

- LDL goal + 30

8

How do we treat lipid disorders?

- resins
- nicotinic acid
- fibrates
- STATINS (best for reducing the risk of cardiovascular events).

9

What are the new agents for treating lipid disorders?

- PCSK9 inhibitors= allow more LDL receptors to be recycled and present on the surface of cells to remove LDL-particles from the extracellular space (best and extremely effective when in combination with statins at lowering LDL cholesterol).
- cholesterol blockers
- mitochondrial transfer protein inhibitors
- CETP inhibitors

10

How does LDL specifically vary according to density?

- more dense LDL= more atherogenic.
*proportion of small, dense LDL particles is greater in pts with metabolic syndrome or DM vs. general population.

11

What happens to Apo B and Apo A-I in DM?

- Apo B= increased
- Apo A-I= decreased

12

What are the types of fish oil and do they help?

- EPA or DHA
*EPA helps more to lower TGs, but studies are ongoing.

13

What is Lpa?

- identical to LDL particle except for addition of apoA.
- plasma concentration is predictive of atherosclerotic disease.
- binds apoB containing lipoproteins and proteoglycans.
*thus important to lower.

14

Is homocysteine linked to atherogenesis?

- YES

15

How can we lower homocysteine levels?

- folate and vitamin B6 may reduce CVD risk.

16

54 y/o pt comes in with Total cholesterol of 250, LDL= 150 (high), TG= 110, HDL= 34. How do we treat to lower his LDL?

- STATIN with LDL goal of less than 100.
