Class III
No benefit or harm
Level A-B of Evidence
A = most C= least
Dietary advice for LDL lowering
Intake of veggies, fruits, whole grains, low-fat dairy, pultry, fish, legumes, non-tropical veg oil
Limit sweets, sodas, red meats
5-6% of total calories form saturate fats
Reduce calories from trans fat
Exercise fo Dyslipidemia
Aerobic activity Decrease LDL and Increase HDL 3-4 sessions, 40 minutes per session Moderate to vigorous activity Resistance training may decrease LDL, TG and non HDL
Optimal LDL
<100
HDL levels
> 41
Desirable TC
<200
Total Cholesterol =
HDL, LDL, and TGs
So just bc this is high doesn’t mean the bad stuff is high
CK Labs
Creatinine Kinase to see if there is muscle breakdown
Who should have CK labs taken?
Personal history of statin intolerance FH of statin intolerance or muscle disease Concomitant therapy that make increase risk of interactions Clinical presentation (not serial)
Secondary causes of elevated LDL
saturated or trans fat, weight gain, anorexia
Giuretics, cyclosporine, glucocorticoids, amiodarone
Bilary obstruction, nephrotic syndrome
Hypothyroidism, obesity, pregnancy
Secondary causes of elevated TGs
Weight gain, lower fat diet, high intake of refine carbs, alcohol
Oral estrogens, glucocorticoids, BAS, PI, anabolic steroids, BB, thiazides
Nephrotic syndrome, CRF, lipodystrophies
DM, hypothyroidism, obesity, pregnancy
Risk factors for ASCVD
Primary relative with LDL >160 or genetic hyperlipidemia
Premature ASCVD in primary relative (men less than 55, women less than65)
Elevated hs-CRP >2
Elevated CAC
Ankle-branchial index less than 0.9
Primary Therapy
Statin based
- Decreases LDL
- Increases HDL and decreased TGs
Primary prevention =
Have NOT had a CV event before
Secondary prevention =
Have had a CV event before
High intensity treatment =
Needing 50% or more decrease in LDL levels
</=75 yeras without contraindication
No drug-drug interaction
No history of intolerance
— someone who has already had a MI should be on high
Moderate intensity treatment =
Needing 30-49% decrease in LDL levels
>75 years
Not able to tolerate high intensity
TG > 500 =
Assess underlying causes and target first because it can lead to pancreatitis
Statin Benefit Groups - Clinical ASCVD
ACS (heart attack) History of MI Stabel or unstable angina Coronary or arterial revascularization (stent) Stroke or TIA PAD of atherosclerotic origin High risk of havinga future ASCVD
High intensity drugs
Atorvastatin (Lipitor) 40-80 mg
Rosuvastatin (Crestor) 20-40 mg
Other groups that benefit from statin therapy
Primary elevations in adults greater than 21 with greater than 190 mg/dL
Primary prevention Diabetes age 40-75 with LDL 70-189 mg/dL
Primary prevention with LDL 70-189 mg/dL
Primary elevations in adults >21 with > 190 mg/dL
At high risk bc of genetic causes (FH)
Should receive high intensity and should intensify until at least greater than 50% LDL reduction
After max on statin, can add other drugs to help
Need to screen family members
Primary Prevention Diabetes age 40-75 with LDL 70-189 mg/dL
At least moderate therapy
If 10 year risk is greater than 7.5% consider high
If less than 40 or greater than 75 weigh risks and benefits
Primary prevention with LDL 70-189 mg/dL
Pool Cohort Equation: Estimate 10 year and lifetime risk
Greater than 7.5 moderate to high
5-75 moderate

Increased risk with Fibric acid derivatives
Pain, tenderness, stiffness, cramping, weakness, or fatigue
New onset diabetes
Define myalgia
Muscle aches, soreness or weakness with minimal or no elevation in CK
Define myopathy
Muscle symptoms associated with elevation in CK >10X ULN
Define Rhabdomyolysis
A CK > 10,000 IU/L or 10X ULN with an elevation in serum creatinine or requiring IV hydration therapy
- Dark brown pee (dehydrated)
Treatment of Muscle pain
D/C until it goes away, restart with a low dose of same statin
If it comes back d/c and let resolve and start a low dose different statin
If not the statins fault, restart statin at original dose
Statin contrindications
