Q

Composition of lipoproteins

A
  • a lipid core containing cholesterol ester and triglycerides
  • An outer layer of phospholipids and apo-proteins is wrapped around the core
  • One molecule of Apo B is present for each LDL

Q

Significance of Apo B

A
  • One molecule of Apo B is present for each LDL
  • This allows lipoproteins to travel in the blood
  • They are very small particles and are more atherogenic than normal size

(We don’t routinely measure Apo B)

Q

Explain the exogenous pathway

A
  • Cholesterol and TG from diet travel through GI system to small intestine and are packaged into Chylomicrons
  • These are transported and deposited in muscle and fat tissue
  • Some break down into free fatty acid for energy
  • Others are taken to the liver where they bind to LDL receptor (most LDL receptors in liver – genetic probs, consider)
  • The liver metabolizes cholesterol into bile for elimination in feces

Q

Explain the endogenous pathway

A
  • In the liver, cholesterol & TG are made into VLDL, transported to muscle and fat tissue and broken down for energy and storage
  • VLDLs break down into IDL
  • Some IDL return to liver, others break down into fat and muscle tissues to form LDL
  • LDL binds to LDL receptor and is taken into cells for cell wall synthesis
  • Excessive LDL goes int oblood
  • macrophages – foam cells - plaque*

Q

Goal of dyslipidemia management

A

prevent future ASCVD

  • Definition: Clinical ASCVD (acute coronary syndrome, hx of MI, stable or unstable angina, coronary or other arterial revascularization, stroke , TIA or peripheral arterial disease based on RCT inclusion criteria)
  • Primary and secondary prevention

Q

Examples of primary, secondary, and tertiary prevention in the context of ASCVD

A
  • Primary: diet. For anyone w/history of CAD, checking lipids for screening
  • Secondary: had MI last year and you are treating them
  • Tertiary: full blown symptoms, trying to slow progression/stop symptoms

normally think prmary prevents dz, secondary detects and cures while asymptomatic, tertiary reduces complications

A

Few weeks-4 months onset

77
Q

Statins & myopathy: what are you looking for after D/Cing?

A

Symptoms and CPK should normalize over days to one month after d/c

78
Q

Who is at increased risk for myopathies on statins?

A
  • ARF/CRF
  • Obstructive liver disease
  • Hypothyroidism
  • Concomittant use of drugs interfering with CYP3A4?? Antidepressants, antibiotics, seizure meds. Famous for interactions
  • Gemfibrozil combined therapy
79
Q

How common are myalgias with statins?

A

(2-11%): common

they don’t always know. Ask if feeling weak, trouble climbing stairs, etc.

80
Q

How common is myositis with statins?

A

(0.5%): uncommon

81
Q

How common is rhabdomyolysis with statins?

A

<0.1%:

82
Q

Statins: difference between myalgias, myositis, rhabdomyolysis

A
  • Myalgias: without physical finding, or lab evidence of muscle dysfunction
  • Myositis: Moderate muscle sx and ­ CPK >5-10 x ULN
  • Rhabdomyolysis:
    • Severe muscle Sx (weakness ) and ­­­ CPK, and myoglobinuria and acute renal failure (usually)
83
Q

Statins: what to do if CPK 10x ULN?

A
  • D/C drug, regardless of symptoms
  • CPK returns to nl within 1 month
84
Q

Statins: very athletic and CPK

A

sometimes very athletic have high cpk - take into consideration

85
Q

Statins: hepatic side effects - how common is aminotransferase elevation and what should you expect?

A

0.5 to 5% persistent elevations in amino-transferases in first 3 months (dose-dependent), asymptomatic and resolves spontaneously.

86
Q

Statins: aminotransferase elevation: when to intervene

A

Tx should be d/c if elevation exceed 3x the upper limit of normal of pt has Sxs (eg.,fatigue, wt loss)

87
Q

Statins: FDA recommendations for monitoring LFTs

A
  • FDA indicates if baseline LFTs are normal, further hepatic monitoring is not needed.
    • Not true – we check every 12 weeks (3mths)
88
Q

105
Q

Cholesterol Absorption Inhibitors: Agents

A

Ezetimbe (Zetia)

106
Q

Ezetimbe (Zetia): MOA & effect on lipids

A

Blocks absorption of dietary and biliary cholesterol

decreases LDL (15-20%), decreases TGL (slightly), ­ increases HDL slightly

107
Q

Ezetimibe (Zetia) + statins: effect

A

Enhances reduction of LDL when used with statin, but ­increased incidence of myopathy and ­increased transaminases when co-administered with a statin

108
Q

Ezetimibe (Zetia): effect on clinical events

A
  • Currently no evidence that LDL lowering with ezetimbe provides a corresponding reduction in clinical events.
109
Q

NIacin: absolute and relative C/Is

A

Absolute: chronic liver dz, severe gout

Relative: diabetes, hyperuricemia, PUD

110
Q

Hypertriglyceridemia: prioritizing when high LDL

A

The 1st aim is to reaching LDL goal then lowering TG

111
Q

Mgmt if TGs 150-200 mg/dL

A
  • Intensify wt management
  • Increase physical activity
112
Q

Mgmt if TGs 200-499 mg/dL

A
  • Intensify wt management
  • Increase physical activity
  • Add nicotinic acid or fibrate to further lower VLDL
113
Q

Mgmt if TGs > 500 mg/dL

A

Prevention of pancreatitis!!

  • Intensify wt management
  • Increase physical activity
  • Very low-fat diet (<15% calories from fat)
  • Fibrate or nicotinic acid, fish oils
114
Q

4 Major Statin benefit groups

A
  1. Individuals with clinical ASCVD
  2. Individuals with primary elevations of LDL–C ≥190 mg/dL
  3. Individuals 40 to 75 years of age with diabetes with LDL-C 70-189 mg/dL and without clinical ASCVD
  4. Individuals without clinical ASCVD or diabetes who are 40 to 75 years of age with LDL-C 70-189 mg/dL and an estimated 10-year ASCVD risk of 7.5% or higher
115
Q

High, moderate, and low intensity statin therapy. How much should a daily dose of each lower LDL-C?

A

High Intensity: > 50%

Moderate intensity: 30 to < 50%

Low-intensity: <30%

past: you’d add more agents to meet the target and the patient gets side effects. Now if you reduce by 50%, even if not at target goal, it’s good – don’t need to add more and more. Evidence shows percentage reduction associated w/reduced CVD event risk

116
Q

High intensity statins

A

Atorvastatin/Lipitor: (>40) to 80mg

Rosuvastatin/Crestor: 20 (40) mg

117
Q

Low intensity statins

A

Simvastatin 10mg

Pravastatin 10-20mg

Lovastatin 20mg

Fluvastatin 20-40mg

Pitavastatin 1mg

118
Q

Adolescents: can begin treating at what age?

A

8yo and older

119
Q

LDL thresholds for adolescents

A
  • LDL thresholds different from adults
    • >190 with no other risk factors
    • >160 in the context of obesity and HTN, premature family history of CVD
    • >130 for children with diabetes
120
Q

Pharm therapy for adolescents

A
  • statins (over 8) watch LFTs, CPK
  • Bile acid resins poorly tolerated, no niacin, ? fibrates
121
Q

Other methods used to determine cholesterol risk: not used on daily basis but perhaps in future

A
  • Total/HDL cholesterol ratio
  • Non-HDL cholesterol (Total-HDL)
  • Apo-lipoprotein measurement
  • Hs-CRP (high sensitivity CRP)
122
Q

Total/HDL cholesterol ratio: what is recommended? Why?

A
  • Ratio <4.0 advocated by the Canadian guidelines
  • Better epidemiologic predictor of CV events than LDL , however no trials based on this ratio
123
Q

Non-HDL cholesterol: what is included in measurement?

A

Includes all atherogenic cholesterol (LDL, lipoprotein a, IDL, VLDL)

124
Q

Non-HDL cholesterol: why use this measurment? What is the target?

A
  • Lipid Research clinics program showed slightly stronger predictor of CVD than LDL
  • Secondary target in pts with high triglycerides >200 mg/Dl (ATP III)
  • Goal 30 above LDL goal
125
Q

Apolipoprotein measurement: why use it? Why not use it?

A
  • Apo B/ Apo A-I found to be a better predictor of events than LDL and total/HDL in AMORIS study; best predictor of events on statins in AFCAPS/TexCAPS study
  • Most useful in the hypertriglyceridemic patient (elevated apoB levels)
  • Not universally available and much more expensive
  • Needs more cost-benefit analysis before routine use
126
Q

Hs-CRP (High sensitivity CRP): why use it? Why not?

A
  • Intensity of atherosclerotic process
  • Recommendation of AHA, should be measured in the patient with intermediate Framingham risk (10-20%) with LDL below the cutoff point for tx
  • Questionable correlation with LDL levels
127
Q

What must be done before prescribing anti-dyslipidemic meds?

A

LFT, CPK (A1c, uric acid?) should be done

128
Q

What is the most effective drug to lower LDLs?

A

Statin

129
Q

Most effective drug to lower TGs?

A

Fibric acid and niacin

130
Q

Most effective drug to increase HDL?

A

niacin (then fibrate)

131
Q

When do statins kick in? When to expect max effect?

A

starts after 1 week and its maximum effect after 4-6 weeks

132
Q

When to d/c statin or give alternative?

A

If CPK >10x, LFT >3x, or pt with statin Tx comes w/ muscle pain- d/c statin and give alternative (ie.,other statin, fibrates or niacin)

133
Q

If on pharm mgmt for lipids, when to F/U?

A

every 3 months to check lipid, LFT, CPK,…then 6-12months when pt stable

134
Q

Stance of new guidelines for dyslipidemia on agents other than statins

A

New guideline does not support niacin, fibric acid, fish oils etc due to lack of effectiveness but use your clinical judgment for subgroup of pt

135
Q

What are the new guidelines for cholesterol/obesity/htn?

A
  • Cholesterol Guideline Update (2013ACC/AHA)
  • Hypertension Guideline Update (JNC 8)
  • Obesity Guideline (2013 AHA/ACC/TOS)
  • Lifestyle guideline (2013 AHA/ACC)
