The Vertical Auto Profile (VAP) test offers a comprehensive lipoprotein analysis, identifying more high-risk coronary heart disease patients than standard lipid panels.

Area of Science:

  • Cardiovascular Diagnostics
  • Lipid Metabolism Research
  • Clinical Biochemistry

Background:

  • Standard lipid panels provide limited lipoprotein information.
  • Identifying patients at high risk for coronary heart disease (CHD) is crucial for preventative care.
  • Advanced lipoprotein profiling can offer deeper insights into cardiovascular risk.

Purpose of the Study:

  • To introduce and describe the Vertical Auto Profile (VAP) method for comprehensive lipoprotein cholesterol analysis.
  • To highlight the VAP method's ability to identify patients at high risk for CHD missed by standard tests.
  • To confirm VAP method's compliance with National Cholesterol Education Program guidelines.

Main Methods:

  • The VAP method utilizes ultracentrifugation with a vertical rotor and a single density gradient spin.

  • It measures cholesterol concentrations for total lipoprotein, HDL, LDL, VLDL, Lp(a), and IDL.
  • The method also quantifies lipoprotein subclasses (HDL, LDL, VLDL) and LDL size via LDL maximum time.

    • Main Results:

    • VAP provides a detailed lipoprotein profile, including subclasses and Lp(a).
    • It identifies additional high-risk CHD patients compared to standard lipid panels.
    • The VAP method is compliant with NCEP ATP III guidelines.

    Conclusions:

    • The VAP method is a direct, single test for comprehensive lipoprotein analysis.
    • VAP enhances the identification of individuals at elevated risk for coronary heart disease.
    • This advanced testing provides valuable data for cardiovascular risk assessment and management.
