Achievement of 2011 European low-density lipoprotein cholesterol (LDL-C) goals of either

Abstract

ObjectiveGuidelines published in 2011 by the European Atherosclerosis Society and the European Society of Cardiology recommend a goal of either low-density lipoprotein cholesterol (LDL-C) <70 mg/dl (∼1.8 mmol/l) or ≥50% reduction in LDL-C for patients at very high cardiovascular risk. The aim of this study was to determine the percentage of high-risk patients from the VOYAGER individual patient data meta-analysis treated with rosuvastatin 10–40 mg, atorvastatin 10–80 mg or simvastatin 10–80 mg who achieved this goal. MethodsWe analysed 25,075 patient exposures from high-risk patients. Paired comparisons were made between each rosuvastatin dose and an equal or higher dose of either atorvastatin or simvastatin, with a series of meta-analyses that included only randomised studies that directly compared rosuvastatin and its comparator treatments. ResultsAs statin dose increased, higher percentages of patients achieved LDL-C <70 mg/dl or ≥50% LDL-C reduction. A greater percentage achieved this goal with rosuvastatin 10–40 mg (43.8–79.0%) than with equal or double milligram doses of atorvastatin (16.1–65.2%) or simvastatin (0–39.7%).Paired comparisons showed statistically significant differences for: rosuvastatin 10 mg vs. atorvastatin 10–20 mg and simvastatin 10–20 mg; rosuvastatin 20 mg vs. atorvastatin 20–40 mg and simvastatin 20–80 mg; and rosuvastatin 40 mg vs. atorvastatin 40–80 mg and simvastatin 40–80 mg (all p < 0.001). ConclusionThese data from VOYAGER highlight the importance of an effective statin at an appropriate dose to achieve treatment goals for LDL-C in patients with very high cardiovascular risk.
