Lipoprotein.beta.subparticle.small

Small, dense LDL particles (lipoprotein beta subparticles) are a subset of low-density lipoprotein cholesterol. While total LDL level is important, the particle size matters significantly—small, dense particles penetrate artery walls more easily and are more likely to cause atherosclerosis than larger particles. High levels of small LDL particles indicate increased cardiovascular risk even with normal total cholesterol levels. This advanced lipid test provides additional insight into heart disease risk and may guide more aggressive treatment decisions for cholesterol management.
