LDL Cholesterol
Also known as Low-Density Lipoprotein
The cholesterol carried on low-density lipoproteins — the traditional cardiovascular-risk marker, increasingly supplemented by ApoB.
Definition
LDL cholesterol is a calculated or directly measured estimate of the cholesterol in low-density lipoprotein particles. It's the long-standing cardiovascular-risk marker and target of statin therapy. ApoB is a more granular indicator of particle number, but LDL remains the standard lipid-panel component and is well-validated for primary and secondary prevention.

ApoBApolipoprotein B
The primary atherogenic protein in blood — a better cardiovascular-risk marker than LDL alone.
BiomarkerHDL CholesterolHigh-Density Lipoprotein
The cholesterol carried on high-density lipoproteins — associated with cardiovascular protection but no longer directly targetable.
BiomarkerTriglycerides
Blood fats that reflect dietary and metabolic patterns — elevated values are a sensitive early marker of insulin resistance.
