A 6wk Open-Label, Randomised, Multicentre, Phase IIIb, Parallel Group Study to Compare the Safety & Efficacy of Rosuvastatin 40mg in Comb.With Ezetimibe 10mg in Subjects With Hypercholesterolaemia & CHD or Atherosclerosis or a CHD Risk Equiv. (10 yr Risk Score >20%).

The purpose of this study is to compare 6 weeks of treatment with rosuvastatin alone compared with 6 weeks of treatment of rosuvastatin combined with ezetimibe in achieving low density lipoprotein level goals.

Inclusion Criteria:

• A history of CHD or clinical evidence of atherosclerosis or multiple risk factors that confer a high risk as defined in the protocol.
• Fasting LDL-C concentrations at Visit 1 as defined in the protocol.
• Discontinuation of all lipid lowering therapy at Visit 1.

Exclusion Criteria:

• History of statin induced serious side effects, or serious hypersensitivity reaction to other statins.
• Subjects considered to be unstable by the investigator after the following events: a myocardial infarction (heart attack), unstable angina, myocardial revascularisation or another revascularisation procedure or a transient ischaemic attack (TIA) or stroke.
• Severe congestive cardiac failure (as defined by the protocol - Appendix I).
• Subjects awaiting a planned myocardial revascularisation prior to starting the study (i.e. planned prior to visit 1)..
