Study Description
Brief Summary:
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 or disease Intervention/treatment Phase
Coronary Arteriosclerosis Drug: Atorvastatin Drug: Pravastatin Phase 4

Study Design

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 600 participants
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)
Study Start Date : April 1999
Estimated Study Completion Date : December 2000

Arms and Interventions

Outcome Measures

Primary Outcome Measures :
  1. 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.
  2. The primary efficacy parameter for brachial artery vasoactivity is the nominal change (month 3 - baseline) in the percent arterial diameter change.

Secondary Outcome Measures :
  1. 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.
  2. 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.
