Emerging studies highlight high on-treatment of platelet reactivity (HTPR) as a major hindrance to the secondary prevention of cardiovascular ischemic events. The aim of this systematic review and meta-analysis is to assess the prevalence of HTPR in patients with ischemic stroke (IS) or transient ischemic attack (TIA) and reveal a possible relation with a higher risk of cerebrovascular event recurrence. Studies were selected if they reported absolute numbers or percentages of HTPR with ASA or clopidogrel in IS/TIA patients at any time point after the cerebrovascular event onset and assessed with any type of platelet function tests...

Patients who have had a stroke are at high risk for recurrent stroke, myocardial infarction, and vascular death. Prevention of these events should be initiated promptly after stroke, because many recurrent events occur early, and should be tailored to the precise cause of stroke, which may require specific treatment. Lifestyle advice including abstinence from smoking, regular exercise, Mediterranean-style diet, and reduction of salt intake and alcohol consumption are recommended for all patients with stroke...

BACKGROUND: The association of genetic polymorphisms and clopidogrel efficacy in patients with ischemic stroke or transient ischemic attack (TIA) remains controversial. We performed a systematic review and meta-analysis to assess the association between genetic polymorphisms, especially CYP2C19 genotype, and clopidogrel efficacy for ischemic stroke or TIA. METHODS: We conducted a comprehensive search of PubMed and EMBASE from their inceptions to June 24, 2016. Studies that reported clopidogrel-treated patients with stroke or TIA and with information on genetic polymorphisms were included...

Ischemic stroke represents one of the leading causes of death and disability in both the United States and abroad, particularly for patients with prior ischemic stroke or transient ischemic attack (TIA). A quintessential aspect of secondary stroke prevention is the use of different pharmacological agents, mainly antiplatelets and anticoagulants. Antiplatelets and anticoagulants exhibit their effect by blocking the activation pathways of platelets and the coagulation cascade, respectively. Clinical trials have demonstrated the safety and efficacy of antiplatelets for noncardioembolic stroke prevention, while anticoagulants are more often used for cardioembolic stroke prevention...

BACKGROUND: Microembolic signals (MESs) are direct markers of unstable large artery atherosclerotic plaques. In a previous study, we found that the number of MESs is associated with stroke recurrence and that clopidogrel plus aspirin more effectively reduce the number of MESs than does aspirin alone. Stroke recurrence is associated with not only the number of MESs but also the size of the MES, which can theoretically be estimated by monitoring the MES intensity via transcranial doppler (TCD)...

Japanese Guidelines for the Management of Stroke 2015 was published. Here, we describe several points revised from the 2009 edition about "Cerebral infarction and transient ischemic attack (TIA)". The revision points are as follows; 1. Extension of possible time window of intravenous recombinant tissue-plasminogen activator treatment (from within 3 hours to within 4.5 hours); 2. Antiplatelet therapy in acute stage (dual antiplatelet therapy (DAPT) for non-cardioembolic ischemic stroke or TIA); 3. Endovascular recanalization therapy in acute stage; 4...

BACKGROUND AND PURPOSE: Dual antiplatelet therapy (DAPT) with aspirin and clopidogrel for 90 days was recommended as the secondary prevention of minor ischaemic strokes or transient ischaemic attacks (TIAs) in 2014. However, whether the duration of 90 days is optimal for each patient remains unclear. Therefore, the efficacy and safety of short-term (≤3 months) and prolonged (≥1 year) DAPT after stroke or TIA were assessed via a systematic review and meta-analysis. METHODS: The Cochrane Library, Clinical Trials...

OBJECTIVE: Controversy persists regarding the perioperative management of clopidogrel among patients undergoing carotid endarterectomy (CEA). This study examined the effect of preoperative dual antiplatelet therapy (aspirin and clopidogrel) on in-hospital CEA outcomes. METHODS: Patients undergoing CEA in the Vascular Quality Initiative were analyzed (2003-2014). Patients on clopidogrel and aspirin (dual therapy) were compared with patients taking aspirin alone preoperatively...

For secondary stroke prevention, long-term dual antiplatelet therapy is not recommended due to increased bleeding risks. There is no specific evidence for using dual antiplatelet therapy for cervical artery dissection or for adding a second antiplatelet agent after a stroke while taking aspirin monotherapy. For patients with atrial fibrillation and stroke/TIA unable to tolerate warfarin, aspirin monotherapy is reasonable. Dual antiplatelet therapy carries a similar risk of major bleeding as warfarin that offsets reductions in stroke risk...
