The Study of Coronary Atheroma by Intravascular Ultrasound: Effect of Rosuvastatin versus Atorvastatin (SATURN) compared the effect of maximal doses of atorvastatin (80 mg daily) or rosuvastatin (40 mg daily) on the progression of coronary atherosclerosis assessed by intravascular ultrasonography in patients with at least one vessel with 20% stenosis on coronary angiography.
Among the 1,039 patients eligible for analysis after 104 weeks of treatment, those in the rosuvastatin group had lower LDL-C levels (62.6 vs. 70.2 mg/dL [1.62 vs. 1.82 mmol/L], P<0.001), and higher HDL-C levels (50.4 vs. 48.6 mg/dL [1.30 vs. 1.26 mmol/L], P=0.01) than those in the atorvastatin group. Both statins induced regression in the majority of patients: 63.2% with atorvastatin and 68.5% with rosuvastatin for percent atheroma volume (P=0.07) and 64.7% and 71.3%, respectively, for total atheroma volume (P=0.02). Both high-dose statin regimens were well tolerated.
Although treatment with rosuvastatin was associated with a more favorable lipid profile, there were no significant between-group differences in the rates of major clinical events. These rates were extremely low for such a population: 1.6% for myocardial infarction, 0.4% for stroke and 0.3% for cardiovascular death during 24 months follow-up at a central site. These results confirm that intensive lipid-lowering with statins is associated with favorable clinical outcomes but suggest that no substantial additional benefit can be obtained once a LDL-C level as low as 70 mg/dL has been reached in this high-risk population. However, the study was not powered to detect between-group differences in major adverse clinical events.
