- Background Reducing low-density lipoprotein cholesterol (LDL-C) levels decreases cardiovascular risk in direct proportion to the decrease in LDL-C. Design The aim of this study was to assess the importance of baseline LDL-C and choice and dose of statin in achievement of LDL-C goals of 100 and 70mg/dl, using a novel statistical model. The analysis included 30,102 patient exposures to rosuvastatin 10-40mg or atorvastatin 10-80mg from 31 direct comparative trials in the VOYAGER database. Methods For each statin dose, percentage goal achievement was plotted for 20 equally large subgroups defined by baseline LDL-C. Logistic regression analysis was then performed for each statin dose to estimate the percentage of patients reaching target. Best-fit logistic regression curves were plotted pair-wise', comparing each rosuvastatin dose with equal or higher doses of atorvastatin. Results LDL-C <100mg/dl was achieved by 53.7-85.5% of patients on rosuvastatin 10-40mg and 43.3-80.0% of those on atorvastatin 10-80mg, whereas LDL-C <70mg/dl was achieved by 4.5-44.0% of rosuvastatin-treated patients and 6.5-41.4% of those on atorvastatin. Similar differences in efficacy favouring rosuvastatin over equal or double doses of atorvastatin were observed across the range of baseline LDL-C levels for both LDL-C goals, being more pronounced at higher baseline values. Conclusions Baseline LDL-C and choice and dose of statin are important for LDL-C goal achievement. The present analysis may allow prediction of individual patient response to different statins at different doses.
