  Purpose

This study was designed to assess the effects on coronary artery plaque using aggressive lipid-lowering therapy versus moderate lipid-lowering therapy. A substudy will examine the effect of these treatments on brachial artery vasoactivity.


Condition Intervention Phase
Coronary Arteriosclerosis
Drug: Atorvastatin
Drug: Pravastatin
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double-Blind

Further study details as provided by Pfizer:

Primary Outcome Measures:
  • The primary efficacy parameter is the percent change in total plaque volume for all slices of anatomically comparable segments of the target coronary artery from baseline to month 18.
  • The primary efficacy parameter for brachial artery vasoactivity is the nominal change (month 3 - baseline) in the percent arterial diameter change.

Secondary Outcome Measures:
  • The nominal change (month 18 - baseline) in total plaque volume as measured by the sum of plaque areas for all slices of anatomically comparable segments of the target coronary artery.
  • Changes in brachial artery vasoactivity will be correlated with changes in total cholesterol, LDL-C, triglyceride and apolipoprotein B levels following 3 months of treatment.

Criteria

Inclusion Criteria:

  • Angiographic evidence of coronary artery disease as defined by a lesion that has at least 20% reduction in luman diameter by visual (angiographic) estimation in any native coronary artery. LDL cholesterol equal to 125mg/dl - 210mg/dl.

Exclusion Criteria:

  • Patients who are anticipated to undergo coronary bypass surgery or cardiac transplantation during the course of the study. Known major hematologic, neoplastic, metabolic, gastrointestinal or endocrine dysfunction.
