Collagen-Induced Platelet Aggregates, Diabetes, and Aspirin Therapy Predict Clinical Outcomes in Acute Ischemic Stroke.

Background: Aggregation of platelets is a trigger for additional development of larger thrombi. This study aimed to identify factors that may affect platelet aggregability and their role in clinical outcomes in acute ischemic stroke.

Methods: Consecutive acute ischemic stroke patients (n = 352) who were transferred within 24 hours after its onset were enrolled.
