HDL and Triglycerides - Key Levels and Concepts

HDL (High-Density Lipoprotein)

  • Definition and role:

    • HDL stands for High-Density Lipoprotein and is referred to as good cholesterol.
    • It carries unneeded cholesterol back to the liver for processing.
    • By transporting cholesterol away from arteries, HDL helps reduce or prevent plaque buildup in blood vessels.

  • Key levels:

    • Low HDL: < 40\,\text{mg/dL}
    • High HDL: ≥60 mg/dL\ge 60\,\text{mg/dL}

  • Units:

    • All HDL level thresholds are given in mg/dL.

Triglycerides

  • Definition and role:

    • Triglycerides are combinations of fatty acids attached to glycerol.
    • They are normally present in the blood in limited quantities.

  • Level thresholds:

    • Normal: < 150\,\text{mg/dL}
    • Borderline high: 150-199 mg/dL150\text{-}199\,\text{mg/dL}
    • High: 200-499 mg/dL200\text{-}499\,\text{mg/dL}
    • Very high: 500 mg/dL and above500\,\text{mg/dL}\text{ and above}

  • Notes:

    • The ranges classify triglyceride levels based on cardiovascular risk indicators typically used in clinical contexts.
