Primary Outcome Measures:
  • Number of Participants Reaching the LDL-C (Low Density Lipoprotein-Cholesterol) Goal (< 100 mg/dl) After 6 Weeks of Treatment [ Time Frame: After 6 weeks of treatment ]
    Primary objective is to evaluate the proportion of patients achieving LDL-C target <100 mg/dl recommend in National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) after 6 weeks of treatment(vytorin 10/20 vs. atorvastatin 10 mg)

Secondary Outcome Measures:
  • Number of Participants Reaching the LDL-C Goal (< 100 mg/dl) After 12 Weeks of Treatment [ Time Frame: After 12 weeks of the treatment ]
    If patients didn't achieve LDL-C <100 mg/dl after 6 weeks of treatment, they received the double dosage of study drug for the next 6 weeks (vytorin 10/40 or atorvastatin 20 mg) and If achieved LDL-C < 100 mg/dl, they received the same dosage of study drug for the next 6 weeks.
