This Study Uses Ultrasound to Determine Whether Atorvastatin or Pravastatin Effects the Progression of Coronary Plaque.

This study has been completed.

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
Intervention Model: Parallel Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: A Prospective, Randomized, Double-Blind, Multi-Center Study Comparing the Effects of Atorvastatin Versus Pravastatin on the Progression and Quantification of Coronary Atherosclerotic Lesions as Measured by Intravascular Ultrasound (REVERSAL)

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.

Estimated Enrollment: 600
Study Start Date: April 1999
Estimated Study Completion Date: December 2000

Ages Eligible for Study:   30 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

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.
