Platelet Surface CD62p and Serum Vitamin D Levels are Associated with Clopidogrel Resistance in Chinese Patients with Ischemic Stroke
Background: To explore the association of platelet activation markers, vitamin D, and antiplatelet drugs resistance in ischemic stroke patients. Methods: A total of 230 patients with ischemic stroke were enrolled in this study. Platelet aggregation, platelet activation marker (CD62p), and vitamin D were measured after 7-14 days of dual antiplatelet treatment (aspirin  + clopidogrel). All individuals were divided into a drug resistance group and a drug sensitive group according to the platelet maximum aggregation rate induced by antagonist adenosine diphosphate or arachidonic acid.

Platelet Count Predicts Adverse Clinical Outcomes After Ischemic Stroke or TIA: Subgroup Analysis of CNSR II
Conclusion: In ischemic stroke or TIA patients with platelet count within normal range, platelet count may be a qualified predictor for long-term recurrent stroke, mortality, and poor functional outcome. Introduction Platelets exert a critical role in the pathogenesis of atherosclerotic complications of cardio-cerebrovascular disease, contributing to thrombus formation, and embolism (1, 2). Previous literature reported that platelets of various size and density are produced by megakaryocytes of different size and stages of maturation in different clinical conditions, suggesting various platelet patterns in differen...

Aspirin resistance are associated with long-term recurrent stroke events after ischaemic stroke.
CONCLUSION: In conclusion, AR is not uncommon in Chinese stroke patients who receive anti-platelet medications. Patients with AR may have a greater risk of suffering stroke recurrence events. PMID: 28842303 [PubMed - as supplied by publisher]

The efficacy and safety of Hirudin plus Aspirin versus Warfarin in the secondary prevention of Cardioembolic Stroke due to Nonvalvular Atrial Fibrillation: A multicenter prospective cohort study.
Conclusion: Significant difference in efficacy was not detected between warfarin group and hirudin plus aspirin group. Compared with warfarin, hirudin plus aspirin therapy had lower safety risk in the secondary prevention of cardioembolic stroke due to NVAF. PMID: 33526977 [PubMed - in process]

Intravenous thrombolysis versus antiplatelet therapy in minor stroke patients with large vessel occlusion
CONCLUSION: In patients with minor stroke harboring LVO within 4.5-h time window, intravenous t-PA was associated with higher odds for the excellent functional outcome, as compared with the aspirin alone. Further randomized controlled trials are warranted.PMID:36880290 | DOI:10.1111/cns.14124

Evaluation and subgroup analysis of the efficacy and safety of intensive rosuvastatin therapy combined with dual antiplatelet therapy in patients with acute ischemic stroke
ConclusionsWithout increasing bleeding and statin-associated adverse events, intensive rosuvastatin therapy plus 7-day DAPT significantly reduced the risk of recurrent stroke, especially for subgroups with high-risk factors.Clinical trial registration.

CYP2C19 Loss-of-Function Variants Associated with Long-term Ischemic Stroke Events During Clopidogrel Treatment in the Chinese Population
This study aims to determine whether CYP2C19 loss-of-function (LoF) variants were associated with long-term ischemic stroke risk in Chinese primary care patients treated with clopidogrel. Patients treated with clopidogrel were ascertained from a Chinese Electronic Medical Record linked with biobank for a retrospective cohort study. Their medical information was examined for the period from January 2018 to December 2021. Two CYP2C19 major loss of function variants (*2:rs4244285, *3: rs4986893) were genotyped. The clinical outcome was ischemic stroke event. Cox regression analysis was used to evaluate the association between...

Homocysteine Level Predicts Response to Dual Antiplatelet in Women With Minor Stroke or Transient Ischemic Attack: Subanalysis of the CHANCE Trial.
CONCLUSIONS: Homocysteine could be a potential biomarker to discriminate the effects of dual and single antiplatelet therapy in female patients with minor ischemic stroke or high-risk transient ischemic attack.

Study of Pharmacodynamic and Pharmacokinetic Interaction of Bojungikki-Tang with Aspirin in Healthy Subjects and Ischemic Stroke Patients.
Conclusions: These results suggest that coadministration of BJIKT with aspirin may not result in herb-drug interaction. PMID: 29599812 [PubMed]

Aspirin Resistance Predicts Unfavorable Functional Outcome in Acute Ischemic Stroke Patients.
CONCLUSIONS: The results suggest that AR is a meaningful and independent marker to predict short-term functional outcome in patients with ischemic stroke. PMID: 30016728 [PubMed - as supplied by publisher]

Association between insulin resistance and aspirin or clopidogrel resistance in Chinese patients with recent ischemic stroke/TIA.
Conclusions: Insulin resistance was an independent predictor for development of antiplatelet drug resistance in patients with recent minor ischemic stroke or TIA. More attention should be paid to recognize these patients and antithrombotic effect should be monitored when antiplatelet drugs were applied to these patients.
