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

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)|
- 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.
- 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.
