Plaque distribution in clopidogrel responders and low responders as determined by multislice computed tomography.

Via multidetector computed tomography (MDCT) with retrospective electrographic gating, we sought to evaluate whether plaque distribution differs between responders and low responders to clopidogrel treatment. Low response was defined as a post-treatment aggregation of 35% to 70%. In this observational study, we enrolled 62 patients (mean age, 64.
