To what extent do high-intensity statins reduce low-density lipoprotein cholesterol in each of the four statin benefit groups identified by the 2013 American College of Cardiology/American Heart Association guidelines? A VOYAGER meta-analysis

- ACC/AHA 2013 guidelines identify 4 statin benefit groups in high CV risk patients.
- High intensity statins (ATV 40 and 80 mg and RSV 20 and 40 mg) are recommended.
- The VOYAGER database includes 32,258 patients from 37 randomized clinical studies.
- LSM % change and achievement of the anticipated 50% LDL-C reduction were evaluated.
- The choice and dose of statin impact both endpoints; overall and within each group.

BackgroundThe 2013 American College of Cardiology and American Heart Association (ACC/AHA) guidelines identify four patient groups who benefit from moderate- or high-intensity statin treatment; those with: 1) atherosclerotic cardiovascular disease (ASCVD); 2) low-density lipoprotein cholesterol (LDL-C) ≥190 mg/dl; 3) diabetes; or 4) a 10-year ASCVD risk ≥7.5%. High-intensity statins, anticipated to reduce LDL-C by ≥50%, were identified as rosuvastatin 20-40 mg and atorvastatin 40-80 mg.Methods and ResultsIndividual patient data (32,258) from the VOYAGER database of 37 studies were used to calculate least-squares mean (LSM) percentage change in LDL-C during 8496 patient exposures to rosuvastatin 20-40 mg, and atorvastatin 40-80 mg in the four patient benefit groups. LSM percentage reductions in LDL-C with rosuvastatin 20 and 40 mg were greater than with atorvastatin 40 mg, overall and in each statin benefit group, and with rosuvastatin 40 mg were greater than with atorvastatin 80 mg overall and in three of the four benefit groups (all p < 0.05). For example, in the ASCVD group, 40%, 59%, 57% and 71% of patients treated with atorvastatin 40 mg, atorvastatin 80 mg, rosuvastatin 20 mg and rosuvastatin 40 mg, respectively, had a ≥50% reduction in LDL-C.ConclusionsThe choice and dose of statin have an impact both on the percentage LDL-C reduction and achievement of ≥50% reduction in LDL-C, overall and within each of the four statin benefit groups outlined by the 2013 ACC/AHA guidelines. This may be of importance for clinicians in their choice of treatment for individual patients.
