    ABSTRACT: The mechanism underlying statin-induced event reduction in patients with acute coronary syndrome remains unclear. To assess the efficacy of rosuvastatin 20mg versus atorvastatin 80 mg in reducing the apolipoprotein B/apolipoprotein A-1 (apoB/apoA-1) ratio at 3 months. Non-inferiority of rosuvastatin 20mg versus atorvastatin 80 mg in reducing low-density lipoprotein cholesterol at 1 and 3 months was also assessed. Patients with non-ST-elevation acute coronary syndrome were enrolled into this randomized, double blind, parallel-group trial. In total, 753 patients (369, rosuvastatin 20mg; 384, atorvastatin 80 mg) were included in the intention-to-treat analysis; 478 patients (226, rosuvastatin 20mg; 252, atorvastatin 80 mg) were included in the per-protocol analysis. Rosuvastatin 20mg was more effective than atorvastatin 80 mg in decreasing apoB/apoA-1 ratio at 1 month (-44.4% vs -42.9%, p=0.02) but not at 3 months (both -44.4%, p=0.87). Low-density lipoprotein cholesterol decreased by approximately 50% after 1 and 3 months in both groups. Non-inferiority of rosuvastatin 20mg versus atorvastatin 80 mg was demonstrated at 1 month (difference, -0.3% [95% confidence interval, -2.7; +2.1]), but not at 3 months (+1.0% [-1.6; 3.5]) (intention-to-treat analysis). In the per-protocol analysis, non-inferiority of rosuvastatin 20mg was demonstrated at both 1 (-0.7% [-3.5; 2.0]) and 3 (-0.5% [-3.5; 2.5]) months. In patients with non-ST-elevation acute coronary syndrome, rosuvastatin 20mg decreased apoB/apoA-1 ratio at 1 month more than atorvastatin 80 mg. No difference could be shown at 3 months; thus, the primary endpoint was not met.

    ABSTRACT: The mechanism underlying rapid, statin-induced event reduction in patients with an acute coronary syndrome (ACS) remains to be clarified. The primary objective is to compare the efficacy of rosuvastatin 20 mg/day and atorvastatin 80 mg/day in reducing the apolipoprotein B/apolipoprotein A-1 (apoB/apoA-1) ratio at three months, in ACS patients. Secondary objectives include a comparison of the effects of early-started rosuvastatin and placebo on inflammatory markers. This is a randomized, double-blind, parallel-group study. Patients with non-ST-segment elevation ACS, symptom onset less than 48 h before admission, and for whom a percutaneous coronary intervention is planned, are eligible for inclusion and are randomized into three groups (G1, G2 and G3). The study comprises two double-blind periods. Period 1 starts at hospital admission and lasts until Day 0 (discharge or less or equal to 6 days after admission); patients in G1 receive one tablet of rosuvastatin 20 mg/day and patients in G2 and G3 receive one matching placebo tablet per day. Period 2 starts at Day 0 and lasts for three months; patients in G1 continue to receive rosuvastatin 20 mg/day, patients in G2 receive rosuvastatin 20 mg/day and patients in G3 receive atorvastatin 80 mg/day. Recruitment of 1075 patients will ensure an 80 power to detect a 3% difference in percentage change in the apoB/apoA-1 ratio and a 20% difference in percentage change in high-sensitivity C-reactive protein. Inclusion phase is complete; results will be reported at a later date. This is the first trial investigating the effect of statins on apolipoproteins in ACS patients.
