- Primary Outcome Measures
Name Time Method <p>Our primary endpoints to be investigated:<br /><br>1) Association between shear stress at baseline and plaque geometry and<br /><br>composition at baseline (including wall thickness, cap thickness and lipids).<br /><br>2) Association between shear stress at baseline and plaque geometry and<br /><br>composition changes over time in (including wall thickness, cap thickness and<br /><br>lipids). </p><br>
- Secondary Outcome Measures
Name Time Method <p>1) Association between change in plaque geometry and composition (e.g. wall<br /><br>thickness, cap thickness and lipids) and wall stress changes.<br /><br>2) Association between change in plaque geometry and composition (including<br /><br>wall thickness, cap thickness and lipids) and change in shear stress. </p><br>
