LDL Small
Small dense LDL particles penetrate the arterial intima more easily, oxidize readily, and clear more slowly from blood than larger LDL. High concentrations raise cardiovascular risk even when total LDL cholesterol looks normal and commonly accompany high triglycerides, low HDL, and insulin resistance. Lifestyle changes and triglyceride-lowering therapy tend to reduce them.

What is LDL Small?
Small dense LDL particles penetrate the arterial intima more easily, oxidize readily, and clear more slowly from blood than larger LDL. High concentrations raise cardiovascular risk even when total LDL cholesterol looks normal and commonly accompany high triglycerides, low HDL, and insulin resistance. Lifestyle changes and triglyceride-lowering therapy tend to reduce them.
Why It Matters
Small dense LDL particles are more atherogenic than larger particles, penetrating arterial walls more easily. High levels increase cardiovascular risk even when total LDL cholesterol is normal.
