New cards

Fridegwald equation

TC= (TG/5) + HDL +LDL

*When TG is over 500 we dont look at LDL

2
New cards

Non-HDL-C=

Non-HDL-C= total cholesterol- HDL-C

3
New cards

Primary Lipid Disorder

Genetic diseases should be strongly suspected in a patient with elevated total serum cholesterol greater than 300 mg/dL or in a patient with LDL cholesterol greater than or equal to 190 mg/dL

4
New cards

What are the best lipid-lowering therapy drugs 

Statins

5
New cards

Statins Absolute contraindications

Liver disease, preg/lac

6
New cards

High-intensity statins

Atorvastatin 40 or 80

Rosuvastatin 20 or 40

7
New cards

Moderate Intensity Statins

Atorvastatin 10 or 20

Rosuvastatin 5 or 10

Simvastatin 20-40

Pravastatin 40 or 80

Lovastatin 40 or 80

Fluvastatin 40 BID 

8
New cards

Low Intensity Statins

Pravastatin 10-20

Lovastatin 20

9
New cards

Statin side effects (CNS, GI, Serious)

CNS: headache, insomnia

GI: epigastric discomfort, flatulence, diarrhea, constipation

Serious: hepatitis, rhabdomyolysis 

10
New cards

CYP3A4 inhibtors - Statin interaction

Itraconazole

Ketoconazole

Protease inhibitors (ritonavir)

Amiodarone

Verapamil, diltiazem

11
New cards

Statins ____ the INR when patients are also on____

INR, Warfarin

12
New cards

Bild acid resins and statins interactions

Adsorption

13
New cards

What medcications cause Rhabdomyolysis with statins

Cyclosporine, erythromycin, gemfibrozil, niacin

14
New cards

Statin lab monitoring

 FLP baseline and 6-12 weeks after dose adjustments then every 6-12 months after the goal is reached 

15
New cards

Which statins are the most potent?

Pitavastatin>Rosuvastatin>Atorvastatin 

16
New cards

What indicates rhabdomyolysis?

CL levels→ Normal levels are 45-260 U/L

17
New cards

Which statins decrease TG the most? (Max, Good, Fair)

Max: Rosuvastatin

Good: Atorvastatin

Fair: Simvastatin, pravastatin

18
New cards

Can statins cause diabetes?

The risk of CV events from no treatment is higher than diabetes risk

19
New cards

Ezetimibe (Zetia)

Add on therapy only!!

Well tolerated

No need to adjust for hepatic/renal/gastric

Same lab monitoring as statins

20
New cards

What medications interact with ezetimibe

Cholestyramine reduces ezetimibe AUC

Fibrates can cause cholelithiasis

Cyclosporine can increase serum concn of ezetimibe

21
New cards

Evolocumab(Repatha)

Alirocumab (Praluent)

Used with max statin therapy in adults with heterozygous familial hypercholesteremia and homozygous familial hypercholesterolemia

SEs: itching, flu, nasopharyngitis,

22
New cards

Bempedoic (Nexletol)

Adjunct to diet and max tolerates statin therapy for adults with heterozygous familial hypercholesteremia or CVD who need additional lowering

23
New cards

Inclisiran (Leqvio)

Given in office, rarely used

24
New cards

Fish oil

Used to decrease TG

1)No shark, swordfish or king mackerel

2)Up to 2 meals of shrimp, canned tuna, salmon, pollock, catfish

Mercury poisoning

25
New cards

Lovaza & Vascepa

Lovaza indicated for pts with TG levels over 500

Vascepa lowers TG about 27%

26
New cards

Familial hypercholesteremia

Genetic disorder, untreated LDL-C of 200-400 mg/dL

32
New cards

High CV risk Population

Previous MI/stroke/CVD or multiple CV risk factors

→Difficult to achieve LDL goals despite therapy

33
