Failure of old and new anticoagulants to prevent ischemic stroke in high-risk atrial fibrillation: a case report.
We report the case of an elderly patient with permanent AF and coronary heart disease, who had already suffered an ischemic stroke while on warfarin treatment, and was consequently switched to treatment with an association of Rivaroxaban and Aspirin. Her CHA2DS2-VASc score was 9. The patient developed a severe recurrent disabling ischemic stroke. This case goes to show that the novel direct anticoagulants may fail to prevent recurrent stroke in patients at particularly high risk, even when associated with antiplatelet drugs.

Risk of major bleeding and stroke associated with the use of VKAs, NOACs and aspirin in patients with atrial fibrillation: a cohort study
ConclusionsNOACs were associated with a higher risk on gastrointestinal bleeding, particularly in women. The use of NOACs in patients who are vulnerable for this type of bleeding should be carefully considered. NOACs and VKAs are equally effective in preventing stroke. Aspirin was not effective in the prevention of stroke in AF.

Role of Antiplatelet Therapy in Stroke Prevention in Patients With Atrial Fibrillation.
Authors: Manaktala R, Kluger J Abstract Patients with atrial fibrillation are at increased risk of having a cardioembolic stroke. The use of oral anticoagulation is now well established to prevent strokes in patients with atrial fibrillation and a CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75 years [2 points], diabetes mellitus, prior stroke/transient ischemic attack or thromboembolism [2 points], vascular disease, age 65 to 74 years, and sex category) score of greater than 1, beyond sex. However, the role of antiplatelet therapy, specifically aspirin in low-risk patients or as an alternative to o...

Primary Prevention of Stroke in Chronic Kidney Disease Patients: A Scientific Update
Background: Although chronic kidney disease (CKD) is an independent risk factor for stroke, official recommendations for the primary prevention of stroke in CKD are generally lacking.Summary: We searched PubMed and ISI Web of Science for randomised controlled trials, observational studies, reviews, meta-analyses and guidelines referring to measures of stroke prevention or to the treatment of stroke-associated risk factors (cardiovascular disease in general and atrial fibrillation (AF), arterial hypertension or carotid artery disease in particular) among the CKD population. The use of oral anticoagulation in AF appears safe...

Is von Willebrand factor associated with stroke and death at mid-term in patients with non-valvular atrial fibrillation?
CONCLUSIONS: High vWF plasma concentrations may discriminate patients with NVAF at greater risk of stroke or all-cause death. PMID: 29685722 [PubMed - as supplied by publisher]

Oral Anticoagulants vs. Aspirin for Stroke Prevention in Patients with Non-Valvular Atrial Fibrillation: The Verdict is in
This article summarizes a recently published individual patient meta-analysis of all published RCTs comparing OAC and ASA in AF. In total, 4052 patients randomized to OAC or ASA were similar regarding important prognostic factors. Patients receiving OAC had a significantly lower risk of any stroke (hazard ratio [HR] 0.54 [95% CI 0.43 –0.71]), ischemic stroke (HR 0.48 [0.37–0.63]), or cardiovascular events (HR 0.71 [0.59–0.85]). Patients receiving OAC were more likely to experience major bleeding (HR 1.71 [1.21–2.41]). The benefit of OAC was most prominent in patients at a high risk of stroke and other cardiovascula...

Temporary oral anticoagulation after MitraClip - a strategy to lower the incidence of post-procedural stroke?
CONCLUSIONS: Temporary oral anticoagulation might be a strategy to reduce the incidence of stroke within the first 30 days after the MitraClip procedure. Bleeding events were not significantly altered due to temporary oral anticoagulation. PMID: 30650019 [PubMed - as supplied by publisher]

Antithrombotic Management in Ischemic Stroke with Essential Thrombocythemia: Current Evidence and Dilemmas
Thrombotic diseases like ischemic stroke are common complications of essential thrombocythemia (ET) due to abnormal megakaryopoiesis and platelet dysfunction. Ischemic stroke in ET can occur as a result of both cerebral arterial and venous thrombosis. Management of ET is aimed at preventing vascular complications including thrombosis. Acute management of ischemic stroke in ET is the same as that in the general population without myeloproliferative disorder. However, an ET patient with ischemic stroke is at high risk for re-thrombosis and therefore additionally managed with cytoreductive therapy and antithrombotic agents. G...

Percutaneous Left Atrial Appendage Closure for Stroke Prophylaxis in Patients with Atrial Fibrillation: 2.3 Year Follow-Up of the PROTECT AF Trial.
CONCLUSIONS: The "local" strategy of LAA closure is noninferior to "systemic" anticoagulation with Warfarin. PROTECT AF has, for the first time, implicated the LAA in the pathogenesis of stroke in AF. CLINICAL TRIAL REGISTRATION INFORMATION: Clinicaltrials.gov; Unique Identifier: NCT00129545.

Dabigatran etexilate: management in acute ischemic stroke.
Abstract A 54-year-old man treated with dabigatran experienced new onset of a stroke with a score of 9 on the National Institutes of Health Stroke Scale. Administration of recombinant tissue plasminogen activator (rtPA) was not recommended because of the dabigatran therapy. Angiography showed occlusion of the left middle cerebral artery by an embolic thrombus. Suction thrombectomy achieved flow through the inferior division of the artery. Computed tomography of the head showed possible intracranial hemorrhage, and dabigatran reversal was attempted with prothrombin complex concentrate and recombinant factor VIIa. C...

Novel oral anticoagulants in secondary prevention of stroke
In patients with atrial fibrillation (AF) oral anticoagulation with vitamin-K antagonists (warfarin, phenprocoumon) is effective both for primary and secondary stroke prevention yielding a 60–70% relative reduction in stroke risk compared with placebo, as well as a mortality reduction of 26 percent. Vitamin-K antagonists have a number of well documented shortcomings. Recently the results of randomised trials for three new oral anticoagulants that do not exhibit the limitations of vitamin-K antagonists have been published. These include direct factor Xa inhibitors (rivaroxaban and apixaban) and a direct thrombin inhibitor...

Prevalence of stroke and the need for thromboprophylaxis in young patients with atrial fibrillation: a cohort study
Atrial fibrillation is the most common cardiac arrhythmia, and age is a well-established independent risk factor for stroke in these patients. Whereas high-risk patients clearly benefit from anticoagulation to prevent stroke, less is known about how to treat low-risk patients. Despite the recent guidelines and studies demonstrating no benefit and excess bleeding risk with aspirin, many low-risk patients still receive this medication. Our objective was to determine the stroke rate in young patients with atrial fibrillation, a group of previously unstudied and predominantly low-risk patients. We hypothesized that the event r...

Stroke in atrial fibrillation patients already on oral anticoagulant: What more can be done?
Abstract Oral anticoagulants dramatically reduce the risk of embolic stroke in patients with atrial fibrillation (AF). However, each year, 1 to 3 % of patients will present an ischemic stroke despite being on oral anticoagulant. These events can result from efficacy fluctuations, non-cardioembolic stroke, or insufficient efficacy despite appropriate anticoagulation. There are several therapeutic options depending on presumed mechanism of ischemic stroke. However, none of these options has been specifically evaluated in appropriate studies. These options include: reinforcement of education or change in VKA drugs ...
