Screening for hyperlipidemia
40-75 y/o = non fasting lipids q5yr, earlier if RF present
a1c, eGFR, Lp(a), fasting lipids if TG >4.5
Risk satisfy w/ FRS
Lifestyle recommendations to lower cholesterol
Alcohol use
Physical activity
Wt loss
Smoking cessation
Sufficient sleep
Diet (Mediterranean, Portfolio, DASH)
Target lipid levels + management for low, med + high risk
Low risk (FRS <10%) - lifestyle changes
Moderate risk (FRS 10-19%) - mod intensity statin, expect LDL <30%. Add ezetimibe if LDL >2
High risk (FRS >20%) - high intensity statin, expect LDL <50%, ezetimibe if LDL >2
How to manage LDL >5, pts with DM or CKD + pts w/ ASCVD
LDL >5 or FH = high intensity statin, expect LDL <50%, add ezetimibe if not in target
DM or CKD = mod intensity statin, expect LDL <2, add ezetimibe if LDL >2
ASCVD (MI, ACS, angina, CAD, CVA, TIA, PAD, claudication) = high intensity statin, expect LDL <1.8, add ezetimibe if LDL >1.8, add PCSK9 if LDL >2.2
Screening for HTN
