The Interplay between Stroke Severity, Antiplatelet Use, and Aspirin Resistance in Ischemic Stroke

We were unable to demonstrate a substantial positive influence of prestroke antiplatelet usage on stroke severity. Although the presence of more severe strokes among patients with laboratory resistance suggests a protective influence of aspirin sensitivity on stroke severity, the hypothesis could not be validated as no difference was observed among aspirin-naive and aspirin-sensitive patients with respect to admission NIHSS score or DWI lesion volume.
