Protective Effect of EPA on Cardiovascular Events

Summary

The purpose of this study was to test the hypothesis that the long-term use of highly (\>98%) purified EPA, in addition to HMG-CoA reductase inhibitor (statin), would be more effective than statin alone in preventing cardiovascular events in Japanese patients with hypercholesterolemia.
