CRP/hs-CRP lowering by statins and other drugs used to treat dyslipidemia

Atherosclerosis is recognized as a chronic inflammatory disease, with high-sensitivity C-reactive protein (hs-CRP) serving as a biomarker of cardiovascular risk that persists despite optimal control of traditional risk factors. Landmark trials, like JUPITER (Justification for the Use of Statins in Prevention) and PROVE-IT (Pravastatin or Atorvastatin Evaluation and Infection Therapy), demonstrate the effect of lipid-lowering medications on inflammation. This can have further implications for comprehensive cardiovascular risk reduction.

Statins lower hs-CRP alongside low-density lipoprotein cholesterol (LDL-C), with greater effects from high-intensity regimens. Nonstatin medications have variable effects; for example, the addition of ezetimibe to statin therapy enhances hs-CRP reduction. Bempedoic acid exerts direct anti-inflammatory effects, producing significant hs-CRP lowering. Omega-3 fatty acids also demonstrate favorable effects on inflammatory markers. However, fibrates offer only marginal benefits, and PCSK9 inhibitors (Proprotein Convertase Subtilisin/Kexin type 9) have minimal impact. Residual inflammatory risk persists despite LDL-C control, supporting dual-target strategies.

The evidence supports therapeutic strategies targeting both lipid and inflammatory pathways, with hs-CRP serving as a complementary marker to refine cardiovascular risk stratification and guide treatment intensification in primary and secondary prevention. Future studies should evaluate inflammation-targeted adjunctive therapies to address discordance between lipid control and residual inflammatory risk.
