    Study Notes

    Hyperlipidemia and Lipid Types

    • Hyperlipidemia is a condition characterized by high levels of lipids (fats), including cholesterol and triglycerides, in the blood.
    • Associated with increased risk of atherosclerosis, coronary artery disease (CAD), thrombosis, CVA, pancreatitis (from triglycerides), and increased risk of atherosclerotic cardiovascular disease (ASCVD).
    • Cholesterol is a waxy substance found in blood vital for building cell membranes and hormone synthesis, but harmful in excess.
    • Lipoproteins transport lipids (cholesterol and triglycerides) in the blood.

    Families of Lipoproteins

    • LDL (Low-Density Lipoprotein):

      • Major cholesterol carrier (about 2/3 to ¾).
      • Delivers cholesterol to non-hepatic tissues.
      • Often called "bad" cholesterol.
      • Can accumulate in artery walls, forming plaques, leading to atherosclerosis.
      • Risk for CAD increases with high LDL levels.

    • VLDL (Very Low-Density Lipoprotein):

      • Another type of "bad" cholesterol.
      • Carries triglycerides from the liver to adipose tissue and muscle.
      • Can contribute to plaque buildup in arteries.
      • Triglycerides are the main component, primarily stored in tissues as glycerol fatty acids.

    • HDL (High-Density Lipoprotein):

      • Known as "good" cholesterol.
      • Helps remove other forms of cholesterol from the bloodstream.
      • Carries about 1/3 to ¼ of cholesterol.

    Total Cholesterol, LDL, and HDL Levels

    • Total cholesterol: <200 mg/dL.
    • LDL: <100 mg/dL (levels adjusted based on risk factors).
    • HDL: between 40-59 mg/dL.
