LDL particle size

LDL particle size refers to the physical size of low-density lipoprotein (LDL) particles, often called "bad cholesterol." LDL particles transport cholesterol through the bloodstream. They come in different sizes: small, dense particles and larger, fluffy ones. Smaller LDL particles are more likely to penetrate artery walls and promote plaque buildup, increasing cardiovascular risk. Larger, buoyant LDL particles are considered less harmful because they are less likely to deposit cholesterol in arteries. Understanding LDL particle size provides more detailed information about heart disease risk beyond just LDL cholesterol levels, helping guide personalized prevention and treatment strategies.
