Episode notes
LDL Particle Size and Heart Disease Risk
- LDL cholesterol is not just "good" or "bad" but exists in a spectrum of sizes.
- Smaller, denser LDL particles are linked to higher heart disease risk, even with less cholesterol.
Cholesterol's Role and Lipoprotein Function
- Cholesterol is vital for cell function and all tissues can produce it.
- The liver packages lipids and cholesterol into lipoproteins, primarily to deliver triglycerides.
HDL, LDL, and Heart Disease Risk
- Low HDL cholesterol is associated with increased small, dense LDL and higher heart disease risk.
- Raising HDL doesn't reduce risk as effectively as lowering LDL, suggesting different causal roles.
