C-Reactive Protein as a Prognostic Marker After Lacunar Stroke: Levels of Inflammatory Markers in the Treatment of Stroke Study Clinical Sciences
Conclusions— Among recent lacunar stroke patients, hsCRP levels predict the risk of recurrent strokes and other vascular events. hsCRP did not predict the response to dual antiplatelets. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifier: NCT00059306.

Antiplatelet Loading Improves Behavioral Outcome in a Rabbit Model of Stroke Brief Reports
Conclusions— This study suggests that usual dual antiplatelet loading is clinically beneficial in a validated model of acute stroke. Study of usual dual antiplatelet loading in acute stroke is warranted to provide treatment to stroke victims ineligible for current therapies.

Comparative Risk of Ischemic Stroke Among Users of Clopidogrel Together With Individual Proton Pump Inhibitors Clinical Sciences
Conclusions— PPIs of interest did not increase the rate of ischemic stroke among clopidogrel users when compared with pantoprazole, a PPI thought to be devoid of the potential to interact with clopidogrel.

Advances in our understanding of "resistance" to antiplatelet agents for prevention of ischemic stroke.
Authors: Gorelick PB, Farooq MU Abstract We review the role of aspirin and clopidogrel for prevention of ischemic stroke and explore the concept of antiplatelet therapy resistance both from a laboratory and clinical perspective and genetic polymorphisms that might influence platelet reactivity with clopidogrel administration. Debates have raged over the years about the application of platelet function tests in clinical practice. We conclude that platelet function testing is not indicated in routine clinical practice. This recommendation is supported by clinical guideline statements, a lack of a global platelet func...

Treatment Effect of Clopidogrel Plus Aspirin Within 12 Hours of Acute Minor Stroke or Transient Ischemic Attack Stroke
Conclusions Among patients treated within 12 hours, the combination of clopidogrel and aspirin was more effective than aspirin alone in reducing the risk of recurrent ischemic stroke during the 90-day follow-up and did not increase the hemorrhagic risk. Clinical Trial Registration URL: https://www.clinicaltrials.gov/. Unique identifier: NCT00979589.

Summary of evidence-based guideline update: Prevention of stroke in nonvalvular atrial fibrillation: Report of the Guideline Development Subcommittee of the American Academy of Neurology
Objective: To update the 1998 American Academy of Neurology practice parameter on stroke prevention in nonvalvular atrial fibrillation (NVAF). How often do various technologies identify previously undetected NVAF? Which therapies reduce ischemic stroke risk with the least risk of hemorrhage, including intracranial hemorrhage? The complete guideline on which this summary is based is available as an online data supplement to this article. Methods: Systematic literature review; modified Delphi process recommendation formulation. Major conclusions: In patients with recent cryptogenic stroke, cardiac rhythm monitoring probabl...

Risks and benefits of clopidogrel-aspirin in minor stroke or TIA: Time course analysis of CHANCE
Conclusions: Clopidogrel–aspirin treatment may have a benefit of reducing stroke risk outweighing the potential risk of increased bleeding especially within the first 2 weeks compared with aspirin alone in patients with minor stroke or TIA. Clinicaltrials.gov identifier: NCT00979589. Classification of evidence: This study provides Class II evidence that for patients with minor stroke or TIA, the reduction of stroke risk from clopidogrel plus aspirin within the first 2 weeks outweighs the risk of bleeding compared with aspirin alone.

Antiplatelet Strategies and Outcomes in Patients with Noncardioembolic Ischemic Stroke from a Real-World Study with a Five-Year Follow-Up
In conclusion, clopidogrel is suggested for patients with an ESRS >  3 and aspirin for patients with an ESRS ≤ 3 for the secondary prevention of noncardioembolic ischemic stroke in Chinese patients.

CYP2C19 Loss-of-Function Associated with First-Time Ischemic Stroke in Non-surgical Asymptomatic Carotid Artery Stenosis During Clopidogrel Therapy
This study measures effect ofCYP2C19 genotype on ischemic stroke risk during clopidogrel therapy for asymptomatic, extracranial carotid stenosis patients. Using deidentified electronic health records, patients were selected for retrospective cohort using administrative code for carotid stenosis, availability ofCYP2C19 genotype result, clopidogrel exposure, and established patient care. Patients with intracranial atherosclerosis, aneurysm, arteriovenous malformation, prior ischemic stroke, or observation time<1 month were excluded. Dual antiplatelet therapy patients were included. Patients with carotid endarterectomy or ...

Platelet‐Oriented Inhibition in New TIA and Minor Ischemic Stroke (POINT) Trial: Rationale and design
DiscussionAspirin is the most common antithrombotic given to patients with a stroke or transient ischemic attack, as it reduces the risk of subsequent stroke. This trial expects to determine whether more aggressive antithrombotic therapy with clopidogrel plus aspirin, initiated acutely, is more effective than aspirin alone.

Association of multiple infarctions and ICAS with outcomes of minor stroke and TIA
Conclusions: The presence of multiple infarctions and ICAS were both associated with an increased risk of 90-day ischemic stroke in patients with minor stroke or TIA, while the presence of both imaging features had a combined effect. ClinicalTrials.gov identifier: NCT00979589.

Antiplatelet Regimen for Patients With Breakthrough Strokes While on Aspirin Brief Report
Conclusions—Among patients who experience an ischemic stroke or transient ischemic attack while on aspirin monotherapy, the addition of or a switch to another antiplatelet agent, especially in the first days after index event, is associated with fewer future vascular events, including stroke.
