Risks & Screening

Screening is indicated in

Friedewald Formula (in patients with TG ≤ 400 or LDL ≤ 50)

$$ LDL=Total \ Cholesterol\ -\ HDL \ -\ \frac{TG}{5} $$

Non-HDL Equation only in patients with hypertriglyceridemia

$$ Non\ HDL=Total \ Cholesterol \ - \ HDL $$

Diagnosis

Management

Pharmacological

Lifestyle modifications should be initiated 3-6 months prior to consideration of prescription except those with familial hypercholesterolemia. Indications are

Indication Goal Initial Statin
Age ≥ 21—LDL ≥ 190 LDL < 100 and 50% decrease from initial LDL Moderate (if goal not achieved in 4-12 weeks then high intensity)
Familial Hypercholesterolemia LDL < 70 and 50% decrease from initial LDL High (if goal not achieved in 4-12 weeks then add Ezetimibe, if no response then consider PSCK9-i)
Age ≥ 35—LDL < 190 with no other risks Lifestyle modifications
Age ≥ 35—LDL < 190 with 10-Year CV Risk ≥ 10% LDL < 100 and 30% decrease from initial LDL Low to moderate
Age ≥ 35—LDL < 190 with 10-Year CV Risk < 10% with subclinical ASCVD, CAC > 100, ABI < 0.9, chronic inflammation or first-degree relative with premature ASCVD LDL < 100 and 30% decrease from initial LDL Low to moderate
Age ≥ 40 with DM and 0-1 risk factors LDL < 100 and 30-50% decrease from initial LDL Moderate

Non-pharmacological

Dietary Control

General Considerations

LDL reduction

TG reduction

*Familial chylomicronemia syndrome : fat 10-15 g/d with medium chain TG oil 30 g/d

Other Modalities

Follow-up
