Percent reduction in LDL cholesterol following high-intensity statin therapy: potential implications for guidelines and for the prescription of emerging lipid-lowering agents
Key result
High-intensity statin therapy produces wide variability in percent LDL cholesterol reduction, supporting the incorporation of percent reduction targets in clinical guidelines.

Implication
Assess percent LDL-C reduction on high-intensity statins to stratify CV risk; extends prior variability data to support guideline targets.
Key Points
- This research aims to link LDL cholesterol reduction thresholds following high-intensity statin therapy to cardiovascular outcomes.
- Conducted a randomized trial with 17,082 healthy adults receiving rosuvastatin 20 mg daily.
- Assessed variability in LDL cholesterol response using waterfall plots and correlated reductions with cardiovascular event risk.
- Analyzed incidence rates of cardiovascular events among groups based on LDL cholesterol reduction levels.
- 3640 individuals (46.3%) achieved an LDL cholesterol reduction ≥50%; the corresponding primary endpoint incidence rates were 11.2 per 1000 person-years.
- Lower risk of cardiovascular events correlated with greater LDL cholesterol reductions: hazard ratios were 0.43 (95% CI 0.30-0.60) for reductions ≥50% (P < 0.00001).
- Observed relationships also applied to non-HDL cholesterol and apolipoprotein B levels.

Percent LDL cholesterol reductionsurrogate
The variability in LDL-C reduction with high-intensity statins supports using percent reduction targets in guidelines and could help allocate adjunctive therapies like PCSK9 inhibitors.
Cite This Study
Ridker et al. (2016) conducted a review in High LDL cholesterol. High-intensity statin therapy was evaluated on Percent LDL cholesterol reduction. High-intensity statin therapy produces wide variability in percent LDL cholesterol reduction, supporting the incorporation of percent reduction targets in clinical guidelines.
