Indications for Testing

  • Adults – obtain baseline lipid testing and repeat testing every 5 years if normal initial baseline testing

Criteria for Diagnosis

  • ACC/AHA calculator (2013) incorporates additional data versus the Framingham ATP III calculator
    • May overestimate risk of atherosclerotic cardiovascular disease (ASCVD) even more excessively than ATP III calculator
    • Four risk groups for statin use
      • Adults with ASCVD – includes stroke, transient ischemic attack, peripheral vascular disease
      • Adults with diabetes, aged 40-75 years with low-density lipoprotein (LDL) levels 70-189 mg/dL
      • Adults with LDL cholesterol levels of ≥190 mg/dL
      • Adults aged 40-75 years who have LDL levels 70-189 mg/dL and ≥7.5% 10-year risk of atherosclerotic cardiovascular disease
  • Framingham ATP III
    • Identify risk factors present for cardiovascular disease (referred to as ASCVD in current ACC/AHA guidelines)
      • Elevated LDL-C – current gold standard diagnostic risk marker
      • Tobacco use
      • Hypertension – blood pressure >140/90 mmHg or on medication for hypertension
      • Low high-density lipoprotein cholesterol (HDL-C) – <40 mg/dL
        • HDL-C ≥60 mg/dL is considered beneficial and removes one risk factor from the total count
      • Family history of early CVD – <55 years in first-degree male relative or <65 years in first-degree female relative
      • Increased age – men ≥45 years; women ≥55 years
    • If >2 risk factors are present, assess Framingham criteria projections for 10-year CVD risk
  • Initiate lifestyle modifications and/or drug therapy to reduce LDL-C to target concentrations
  • High triglycerides (TG) – >150 mg/dL
    • Lifestyle modifications
    • If TG ≥200 mg/dL, non-HDL-C target is set 30 mg/dL higher than LDL-C target

Laboratory Testing

  • Determine lipoprotein concentrations using fasting lipid testing
    • LDL-C, HDL-C and TG – minimum testing recommendation
    • No consensus guidelines support use of LDL-C subclasses
  • Adults
    • ≤75 years – screen all individuals
    • >75 years – screen individuals who have multiple coronary artery disease risk factors
  • Initial screen – fasting lipid panel with LDL-C, HDL-C, and TG
  • ADA/ACC consensus – consider Apo B monitoring in patients with LDL-C <130 mg/dL with a goal of 80 mg/dL in highest-risk patients
  • ACC/AHA (2013) guideline deemphasizes fixed goals for LDL-C and HDL
    • Lipid measurement – 1-3 months after statin initiation and yearly thereafter

Cardiovascular disease (CVD) (referred to as atherosclerotic cardiovascular disease [ASCVD] in current ACC/AHA guidelines) is a major cause of morbidity and mortality in the U.S.

Epidemiology

  • Prevalence – 1.2 million myocardial infarctions annually in U.S.
  • Age – risk increases with age
  • Sex – M>F

Risk Factors for CVD

Basis of Risk Assessment

  • Statins shown to reduce LDL-C concentrations and to reduce cardiovascular mortality in numerous trials
    • Identifying patients who will benefit from drug therapy is important for early prevention and intervention
  • Adult Treatment Panel (ATP) III guidelines (Framingham Heart Study)
    • Identify patients at risk for development of CVD
    • Develop plan of action for at-risk patients, including target goals for LDL-C and triglycerides (TG)

Clinical Background

Epidemiology

  • Prevalence – in last 10 years, increasing prevalence of hyperlipidemia in children, which mirrors increasing level of obesity
    • ~20% of youth 12-19 years have abnormal cholesterol values

Diagnosis

Indications for Testing

Laboratory Testing

Screening

  • U.S. Preventive Services Task Force (USPSTF, 2007) – insufficient evidence to recommend screening
  • American Academy of Pediatrics (2008) – screen children and adults (fasting lipid profile)
    • Recommended if family history of CVD or other CVD risk factors
    • No definitive data exists to show which cholesterol level predicts risk of adult CVD
    • If levels acceptable, repeat every 3-5 years
