Dyslipidemia Flashcards
Calculate LDL (using the Friedrickson equation)
LDL = Total CH - HDL — (TG/’5)
This formula can not be used when the TGs are > 400 mg/dL
Calculate LDL (using the Friedewald equation)
LDL = Total CH - HDL — (TG/’5)
This formula can not be used when the TGs are > 400 mg/dL
Identification of 4 Statin Benefit Groups
1- ASCVD including ACS s/p MI, stable or unstable angina ,stroke, TIA, etc.
2- Primary elevations of LDL > 190 mg/dL
3- Diabetes and 40-75 years of age with LDL between 70- 189 mg/dL
4- 40-75 years of age with LDL between 70-189 mg/dL and estimated 10-year ASCVD risk of >, = 7.5%

Statin Pt Counselling
- Lifestyle changes including a heart healthy food
pattern and exercise - Contact PCP right away if you have
muscle weakness, tenderness, aching, cramps, stiffness or pain that happens without a good reason, especially if you also have a fever or feel more tired than usual. These may be symptoms of muscle damage. - Contact PCP right away if you are passing brown or dark-colored urine, have pale stools, feel more tired than usual or if your skin and/or whites of your eyes become yellow. These may be symptoms of liver damage.
