Ponatinib-induced ischemic stroke in larval zebrafish for drug screening.
In this study, using Ponatinib as an inducer, we developed and characterized a zebrafish ischemic stroke model. This zebrafish ischemic stroke had the cerebral vascular endothelial injury, thrombosis, reduced blood flow, inflammation and apoptosis as well as the reduced motility. The zebrafish ischemic stroke model was validated with 6 known human therapeutic drugs of ischemic stroke (Aspirin, Clopidogrel, Naoxintong capsules, Edaravone, Xingnaojing injection, Shuxuening injection). The mRNA levels of the neovascularization-related gene (vegfaa) and vascular endothelial growth factor receptor gene (VEGFR), neurodevelopment...

Associations of CYP3A4, NR1I2, CYP2C19 and P2RY12 polymorphisms with clopidogrel resistance in Chinese patients with ischemic stroke.
CONCLUSION: The individuals with both the CYP2C19(*)2 allele and hypertension are at high risk of CR during anti-thrombosis therapy. The CYP3A4(*)1G allele, P2RY12 (rs2046934) C allele and NR1I2 (rs13059232) CC genotype may be protective factors for CR. The associated SNPs studied may be useful to predict clopidogrel resistance in Chinese patients with ischemic stroke. PMID: 27133299 [PubMed - as supplied by publisher]

Therapeutic Challenges in Patients With Noncardioembolic Acute Ischemic Stroke in Need of Double Antiplatelet Therapy for Coronary Artery Disease
Conclusions: In the acute phase of an IS, maintenance or initiation of DAPT therapy imposed by CHD relies, on one hand, on the risk of hemorrhagic transformation of the brain injury and, on the other hand, on the risk of stent thrombosis in the coronary arteries. The management of these patients must be carried on by a vascular team, on an individualized basis.

Antithrombotic Therapy for Prevention of Various Thrombotic Diseases
Abstract The majority of sudden onset serious diseases, such as acute myocardial infarction, ischemic stroke, and pulmonary embolism, are thrombotic diseases. Antithrombotic therapy in general has a potential to reduce the risk of thrombotic diseases, though it increases the risk of serious bleeding events. Of the various antithrombotic agents currently available, the antiplatelet agent aspirin and the anticoagulant agent warfarin have the most robust clinical evidence. Aspirin reduces the risk of cardiovascular (CV) death, recurrence of myocardial infarction and ischemic stroke by up to 25%. Aspirin is an establish...

Comparative efficacy and safety of antiplatelet or anticoagulant therapy in patients with chronic coronary syndromes after percutaneous coronary intervention: A network meta-analysis of randomized controlled trials
Aimed to evaluate and compare the interactive effects of different antiplatelet or anticoagulation strategies in patients with chronic coronary syndromes (CCS) after percutaneous coronary intervention (PCI). Randomized controlled trials comparing different antiplatelet or anticoagulant strategies in patients with CCS after PCI were included. The primary outcomes were major adverse cardiovascular event (MACE), mortality, ischemic and bleeding events. Compared to aspirin alone, addition of prasugrel or ticagrelor to aspirin resulted in lower risk of myocardial infarction (MI) [odds ratio (OR): 0.38 (95% confidence interval 0...

P2Y12 receptor antagonists: which one to choose? A systematic review and meta-analysis.
Conclusion: Newer P2Y12 receptor antagonists are associated with better cardiovascular outcomes in patients with ACS and/or undergoing PCI. Prasugrel use resulted in higher major bleeding rates and no overall mortality benefit compared with clopidogrel. PMID: 27290917 [PubMed - as supplied by publisher]

Oral Anticoagulants With Dual Antiplatelet Therapy Versus Clopidogrel in Patients After Percutaneous Coronary Intervention: A Meta-Analysis
Conclusions: In patients who are on OAC with vitamin K antagonist and underwent percutaneous coronary intervention, no significant differences were found in mortality, ischemic, and hemorrhagic complications between the patients treated with TT and DT. Thus, tailored treatment based on individual thromboembolic and bleeding risk might be the most reasonable approach in these patients.

Efficacy and Safety of Ticagrelor Compared to Clopidogrel in Patients Undergoing Percutaneous Coronary Intervention: A Meta-Analysis.
CONCLUSION: The TA treatment in the European and American populations is more beneficial and safer than CA treatment. However, although the Asian population has this benefit, the risk of bleeding is significantly increased as well, and care should be taken when choosing antiplatelet drugs.

Impact of the ABCD-GENE Score on Clopidogrel Clinical Effectiveness after PCI: A Multi-site, Real-world Investigation
The objective of this study was to validate the ability of ABCD-GENE score to predict risk for atherothrombotic events in a diverse, real-world population of clopidogrel-treated PCI patients who received clinical CYP2C19 genotyping to guide antiplatelet therapy. A total of 2341 adult patients who underwent PCI, were genotyped for CYP2C19, and received treatment with clopidogrel across four institutions were included (mean age 64±12 years, 35% female, 20% Black). The primary outcome was major atherothrombotic events, defined as the composite of all-cause death, myocardial infarction, ischemic stroke, stent thrombosis, or r...

RCT: Clopidogrel with or without aspirin in patients taking oral anticoagulant therapy and undergoing percutaneous coronary intervention (WOEST)
Source: Lancet Area: News If percutaneous coronary intervention (PCI) is required in patients taking oral anticoagulants, double antiplatelet therapy with aspirin and clopidogrel is indicated. However, such triple therapy increases the risk of serious bleeding and this treatment strategy has not been tested prospectively.   Omission of oral anticoagulants could lead to an increased risk of thrombotic stroke, whereas clopidogrel is essential to prevent stent thrombosis. The exclusion of aspirin might, therefore, be useful to reduce the bleeding risk in patients with coronary artery disease.   The open-lab...

Analysis of gastrointestinal prophylaxis in patients receiving dual antiplatelet therapy with aspirin and clopidogrel.
CONCLUSION: More than half of the patients did not receive GI prophylaxis appropriately. The most common reason for nonadherence to the consensus document was no prophylaxis when indicated. Vascular events could not be directly attributed to PPI use, and GI events occurred despite prophylaxis. Overall, there was a low incidence of adverse events related to the use of PPI therapy.  PMID: 24456320 [PubMed - indexed for MEDLINE]

Genetic and platelet function testing of antiplatelet therapy for percutaneous coronary intervention: the ARCTIC-GENE study
Conclusions The genetic clopidogrel profile was a good marker of platelet function response on clopidogrel but was not related to clinical outcome suggesting that the genetic added little to the pharmacodynamic information used in the study to adjust antiplatelet therapy. ClinicalTrials.gov: NCT00827411.

Predictors of Direct Oral Anticoagulants Utilization for Thromboembolism Prevention in Atrial Fibrillation.
CONCLUSION: To the best of our knowledge, this is the first observational study finding that concomitant use of clopidogrel reduced the likelihood of DOAC utilization while prescription by a neurologist increased the probability of receiving a DOAC over warfarin in patients with AF.This article is open to POST-PUBLICATION REVIEW.
