- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: DOUBLE
- Phase: PHASE3
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Primary hypercholesterolemic participants with known coronary heart disease (CHD) or multiple risk factors for CHD (≥2) not meeting the target low-density-lipoprotein cholesterol (LDL-C) of ≤100 mg/dL (2.59 mmol/L), with plasma LDL-C ≥130 mg/dL (3.37 mmol/L) and plasma triglycerides (TG) ≤350 mg/dL (3.99 mmol/L) while on starting-dose (10 mg) atorvastatin at least 4 weeks before initial qualifying lipid determination.~* Participants with heterozygous familial hypercholesterolemia (HeFH) not meeting the target LDL-C of ≤100 mg/dL (2.59 mmol/L), with plasma LDL-C ≥130 mg/dL (3.37 mmol/L) and plasma TG ≤350 mg/dL (3.99 mmol/L) while on starting-dose (10 mg) atorvastatin for at least 4 weeks before initial lipid qualifying determination. HeFH is defined by: a) genetic testing; or b) LDL-C \>190 mg/dL (4.9 mmol/L) and at least one of the following: (1) xanthomata in first or second degree relative; (2) family history of myocardial infarction under age 60 years in a first degree relative or family history of myocardial infarction under age 50 years in a second degree relative; (3) family history of total cholesterol (TC) \>290 mg/dL (\>7.5 mmol/L) in a first or second degree relative.~* All women must have a negative pregnancy test prior to study entry. Women of child-bearing potential must agree to practice an effective barrier method of birth control for the duration of the study, as well as for 1 month following study completion.~* Postmenopausal women who are receiving postmenopausal hormonal therapy or raloxifene must be maintained on a stable estrogen replacement therapy (ERT), estrogen/progestin hormone replacement therapy (HRT) or raloxifene regimen during the study period.~* Participants must be willing to observe the National Cholesterol Education Program (NCEP) Step I diet as determined by a Ratio of Ingested Saturated fat and Cholesterol to Calories (RISCC) score not greater than 24 throughout this study. Ability to complete diet diaries needs to be demonstrated.~Exclusion Criteria:~* Individuals with a history of mental instability, drug/alcohol abuse within the past 5 years or individuals who have been treated or are being treated for severe psychiatric illness which in the opinion of the Investigator, may interfere with optimal participation in the study.~* Underlying disease likely to limit life span to less than 1 year.~* Participants who have previously been randomized in any of the studies evaluating ezetimibe.~* Participants with known hypersensitivity or any contraindication to atorvastatin~* Pregnant or lactating women.~* Participants with congestive heart failure New York Heart Association (NYHA) Class III or IV.~* Participants with uncontrolled cardiac arrhythmias~* Participants with myocardial infarction, coronary bypass surgery or angioplasty within 3 months of study entry.~* Participants with unstable or severe peripheral artery disease within 3 months of study entry.~* Participants with unstable angina pectoris.~* Participants with disorders of the hematologic, digestive or central nervous systems including cerebrovascular disease and degenerative disease that would limit study evaluation or participation.~* Participants with uncontrolled (as determined by hemoglobin A1c \[HbA1c\]) or newly diagnosed (within 1 month of study entry) diabetes mellitus.~* Participants with uncontrolled endocrine or metabolic disease known to influence serum lipids or lipoproteins. Clinically euthyroid participants on replacement doses of thyroid hormone are eligible for enrollment.~* Participants with known impairment of renal function (creatinine \>2.0 mg/dL), dysproteinemia, nephrotic syndrome or other renal disease (24-hour urinary protein 3+ or 1 gram).~* Participants with active or chronic hepatobiliary or hepatic disease (participants with aspartate aminotransferase (AST) or alanine aminotransferase (ALT) \>2 times the upper limit of the central laboratory reference range \[ULN\] will be excluded).~* Participants who are known to be human immunodeficiency virus (HIV) positive.~* Participants with known coagulopathy (prothrombin time \[PT\] or partial thromboplastin time \[PTT\] at Visit 2 \>1.25 times control).

Study Arms:
- Atorvastatin Monotherapy (Type: EXPERIMENTAL): Participants receive double-blind atorvastatin 10 mg once daily (QD) via oral tablet PLUS open-label atorvastatin 10 mg QD via oral tablet for the entire duration of the study. Double-blind atorvastatin is to be added to the regimen for participants not achieving LDL-C target (≤100 mg/dL; 2.59 mmol/L). The maximum possible total daily dose of atorvastatin received in this group is 80 mg (10 mg open label plus 70 mg double blind).
- Ezetimibe + Atorvastatin (Type: EXPERIMENTAL): Participants receive double-blind ezetimibe 10 mg QD via oral tablet PLUS open-label atorvastatin 10 mg QD via oral tablet for the entire duration of the study. Double-blind atorvastatin is to be added to the regimen for participants not achieving LDL-C target (≤100 mg/dL; 2.59 mmol/L). The maximum possible total daily dose of atorvastatin received in this group is 40 mg (10 mg open label plus 30 mg double blind).
