Indications

Clinical significance

mean total cholesterol & HDL cholesterol vary by < 2%, with differing fasting times[8]

  • HDL cholesterol does not vary with age in men or post-menopausal women

mean LDL cholesterol varies by < 10% with differing fasting times[8]

  • fasting & non-fasting LDL-cholesterol determinations yield similar prognostic value for all-cause mortality[11][13]
  • LDL cholesterol decreases with frailty & poor healh

mean serum triglcerides varies by < 20% with differing fasting times[8]

post-prandial serum triglycerides are increased in the elderly

When triglycerides are > 200 mg/dL, non HDL-cholesterol is the target for lipid-lowering therapy. Add 30 mg/dL to the LDL-cholesterol goal.[3]

Even when triglycerides are < 200 mg/dL, non HDL-cholesterol may be target for lipid-lowering therapy.[7]

Measuring only total cholesterol & HDL cholesterol is equivalent to fasting lipid panel for cardiovascular risk assessment:

  • does not require fasting
  • risks for coronary disease & ischemic stroke are not associated with serum triglyceride levels

A novel method to estimate LDL-cholesterol using an adjustable factor for the triglyderide:VLDL-cholesterol ratio derived from a 180 cell table provides more accurate risk classification than the standard method of TC/5[10]

Concentrations of cholesterol, HDL cholesterol & triglycerides obtained within 24 hours of acute myocardial infarction reflect preinfarct levels. After 24 hours, cholesterol levels decline, triglycerides may markedly increase & HDL cholesterol levels are unpredictable. Serum cholesterol drops with any acute injury or illness. 4 weeks should be allowed after recovery before obtaining a fasting lipid panel.

NCEP* Adult treatment goals for LDL-cholesterol & non-HDL cholesterol#

Risk Factor@ LDL goal non-HDL goal
Absent 160 190
Present 130 160
Coronary Artery Disease 100 130
high risk 70 100

* National Cholesterol Education Program

# all values in mg/dL

@ Risk Factor - 2 or more of the following:

  • male sex
  • family history of CAD < 55 years of age
  • hypertension
  • smoking
  • obesity
  • diabetes mellitus
  • HDL-cholesterol < 40 mg/dL
  • non-coronary artery atherosclerosis

For moderately-high or high risk patients, lipid-lowering drug therapy (statin, niacin) should achieve a least 30-40% reduction in LDL cholesterol[3]

Mortality in patients > 65 years of age not associated any lipid measurement.

HDL inversely associated with myocardial infarction (hazard ratio = 0.85) in this age group

Specimen

Procedure

* serum LDL cholesterol is generally calculated using the equation:

(LDL-cholesterol = Total Cholesterol - HDL-cholesterol - TG/5)*

(non-HDL cholesterol = Total Cholesterol - HDL-cholesterol)[3]

* TG = triglycerides in serum (mg/dL) Cholesterol = cholesterol in serum (mg/dL)

When serum triglycerides > 400 mg/dL, fasting lipid panel recommended, otherwise fasting is unnecessary[13]
