Brief Summary

In summary, the CHILLAS study will be the first multicenter study performed in a Chinese population using a patient-level analysis to compare the effects and safety of intensive statin therapy with that of moderate statin therapy. Therefore, it will determine whether "lower is better", that is, whether LDL cholesterol lowering to a level of approximately 100mg/dl provides a benefit inferior to that of LDL cholesterol lowering to a much lower level; examine the role of inflammatory markers in predicting cardiac events and response to statin therapy; and evaluate the effects of statin therapy on regression of coronary atherosclerosis using IVUS.
