IMPROVE-IT (TIMI 40) determined whether the addition of ezetimibe to statin therapy, using ezetimibe/simvastatin, improves cardiovascular outcomes compared with simvastatin monotherapy in patients after ACS. In addition, the difference in achieved LDL-C levels between the groups provided data on whether the target for LDL-C lowering should be reduced further.
