Brief Summary:
To evaluate the percentage of patients with either established cardiovascular disease (CVD), at "high risk" of developing CVD or with diabetes who are on simvastatin 40mg, with fasting LDL-C > 2mmol/l, who are able to attain the recommended LDL-C target of < 2mmol/l following 6 weeks treatment with either ezetimibe/simvastatin 10/40mg, atorvastatin 40mg or rosuvastatin 10mg.

Condition or disease Intervention/treatment Phase

Arm Intervention/treatment
Experimental: 1
Arm 1: Drug
Drug: ezetimibe (+) simvastatin
ezetimibe (+) simvastatin 10/40mg. once daily tablet formulation, all tablet form, taken orally, cholesterol lowering medication.
Other Name: MK0653A

Active Comparator: 2
Arm 2: Active comparator
Drug: Comparator: atorvastatin
atorvastatin 40mg. once daily tablet formulation, all tablet form, taken orally

Primary Outcome Measures :
  1. Percentage of Patients Achieving a Target of Fasting LDL-C of <2mmol/l at Study End [ Time Frame: 6 Weeks ]
    Fasting LDL-C was the primary efficacy variable. The primary efficacy analysis was based on the proportion of patients achieving a target of <2mmol/l in fasting LDL-C at study end.
