 Non ST-segment elevated acute coronary syndromeNSTE-ACS is increasing rapidly, and is more frequent than ST-segment elevated acute coronary syndrome STE-ACS now. NSTE-ACS patients sent to early PCI procedure is large and increasing rapidly in China.Quite a few trials have focused on high loading dose statin before PCI to improve cardiovascular outcomes in ACS. In Asian, high loading dose statin therapy showed different outcome. Rosuvastatin RSV is one of the most potent statins.Nowadays, quite a few experts think ACS patients undergoing PCI not only need loading dose statin, but also post PCI intensive statin treatment is rather important. Chinese consensus and western guidelines recommend intensive statin treatment in these patients. However, Chinese consensus referred to the western study as theres no relevant intensive statin treatment peri-PCI study in China until now.
