Evidence-based goals in LDL-C reduction

Abstract

The evidence from trials of statin therapy suggests that benefits in cardiovascular disease (CVD) event reduction are proportional to the magnitude of low-density lipoprotein cholesterol (LDL-C) lowering. The lack of a threshold at which LDL-C lowering is not beneficial, in terms of CVD prevention observed in these trials, is supported by epidemiological and genetic studies reporting the cardio-protective effects of lifelong low exposure to atherogenic cholesterol in a graded fashion. Providing that intensive LDL-C lowering is safe, these observations suggest that many individuals even at current LDL-C treatment targets could benefit. Here, we review recent safety and efficacy data from trials of adjunctive therapy, with LDL-C lowering beyond that achieved by statin therapy, and their potential implications for current guideline targets. Finally, the application of current guidance in the context of pre-treatment LDL-C concentration and deployment of statin therapy is also discussed. The number of patients requiring treatment to prevent a CVD event with statin treatment has been shown to differ markedly according to the pre-treatment LDL-C concentration even when absolute CVD risk is similar. It produces more likelihood of benefit when absolute LDL-C reduction is greater which is largely dependent on pre-treatment LDL-C concentration. This also has to be taken in consideration when deploying new agents like proprotein convertase subtilisin/kexin type 9 monoclonal antibodies. Patients with highest LDL-C concentration despite maximum statin and ezetimibe therapy will attain most absolute LDL-C reduction when treated with proprotein convertase subtilisin/kexin type 9 monoclonal antibodies, hence benefit most in term of CVD risk reduction.

  • Ezetimibe provides additional LDL-C reduction of 15-20% but is often insufficient for high-risk individuals.

    “Additional LDL-C reduction from ezetimibe therapy amounts to 15–20% but it often proves insufficient to meet the needs of individuals at high risk [77].”

    From Inclisiran SiRNA therapy for durable LDL-C reduction: a systematic review and meta-analysis highlighting a breakthrough in long-term cardiovascular risk management (2026) · cites this paper as [77]

    The Interventional studies section (page not provided) reports that adding ezetimibe lowered LDL-C by around 24%, not 15–20%. The Abstract notes that some patients have high LDL-C despite maximum statin and ezetimibe therapy, supporting the point that this combination can be insufficient, but it does not establish how often this occurs among high-risk individuals.

  • It is unlikely that the increase in HDL-C caused by statins makes a substantial contribution to the reduction of events mediated by statins.

    “It is unlikely that this increase in HDL-C makes a substantial contribution to the reduction of events mediated by statins [83–85].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
