Which lipid parameter is most directly reduced by statins?

Statins work by blocking the enzyme that makes cholesterol in the liver, so hepatic cholesterol falls. In response, the liver upregulates LDL receptors and clears LDL particles from the blood more efficiently. This receptor-mediated uptake directly lowers LDL cholesterol, making it the parameter most consistently and markedly reduced by statin therapy. Changes in HDL cholesterol are variable and not reliably increased, and triglycerides may decrease modestly in some patients but not as predictably or directly as LDL-C. Total cholesterol often falls as a result of the LDL-C drop, but LDL-C remains the most specific indicator of a statin’s effect.
