A real world data of dabigatran etexilate: multicenter registry of oral anticoagulants in nonvalvular atrial fibrillation
AbstractAtrial fibrillation (AF) is a common cardiac arrhythmia. Dabigatran etixalate (DE) is one of the new oral anticoagulant drugs being used in nonvalvular AF (NVAF). There is no adequate real world data in different populations about DE. The aim of this registry was to evaluate the efficacy and safety of DE Consecutive NVAF patients treated with warfarin or both DE doses were enrolled during 18  months study period. The patients were re-evaluated at regular 6-month intervals during the follow-up period. During the follow-up period outcomes were documented according to RELY methodology A total of 555 patients were ana...

Early introduction of direct oral anticoagulants in cardioembolic stroke patients with non-valvular atrial fibrillation
AbstractDirect oral anticoagulants (DOACs) are superior to warfarin in reduction of the intracranial bleeding risk. The aim of the present study was to assess whether early DOAC introduction (1 –3 days after onset) in stroke patients with non-valvular atrial fibrillation (nVAF) may be safe and effective, compared with DOAC introduction after 4–7 days. We conducted a prospective analysis based on data collected from 147 consecutive nVAF patients who started DOAC within 7 days after stro ke onset. In all patients, we performed pre-DOAC CT scan 24–36 h after onset and follow-up CT scan at 7 days after DOAC introduction...

An rs13293512 polymorphism in the promoter of let-7 is associated with a reduced risk of ischemic stroke
AbstractThe expression of let-7 family members was differentiated in ischemic stroke (IS), functioning as an important regulating molecular in the pathophysiology of stroke. We hypothesized that genetic polymorphism in the promoters of let-7 family may be associated with the risk of IS. To test this hypothesis, we investigated the association of the rs10877887 and rs13293512 in the promoters of let-7 family with the susceptibility to IS. A hospital-based case –control study was performed. The rs10877887 genotype was determined by using a polymerase chain reaction-restriction fragment length polymorphism assay, and the rs...

Direct oral anticoagulant use and the incidence of bleeding in the very elderly with atrial fibrillation
AbstractAtrial fibrillation (AF) is a major risk factor for stroke in the elderly population. The use of anticoagulation in patients with AF greatly reduces the risk for stroke, but results in an increased risk of bleeding. Over the past several years, direct oral anticoagulants (DOACs, dabigatran, rivaroxaban, and apixaban) have been used in place of warfarin for stroke prevention in AF. We conducted a retrospective cohort study to assess the safety of DOACs in very elderly patients (75+) managed in a health care system encompassing both community and academic settings. We found that 36  % of patients had moderate to sev...

Reasons for exclusion from intravenous thrombolysis in stroke patients admitted to the Stroke Unit
AbstractIntravenous (IV) thrombolysis is the treatment in ischemic stroke, but only the minority of patients receive this medication. The primary objective of this study was to explore the reasons associated with the decision not to offer IV thrombolysis to stroke patients admitted to the Stroke Unit (SU). We conducted a retrospective analysis based on data collected from 876 consecutive stroke patients admitted to the SU  <12  h of symptoms onset, treated or not with IV thrombolysis at the discretion of the treating neurologist. Of the 876 patients, 449 were thrombolysed and 427 non-thrombolysed. Stroke onset >4....

Safety and efficacy of non-vitamin K oral anticoagulant treatment compared with warfarin in patients with non-valvular atrial fibrillation who develop acute ischemic stroke or transient ischemic attack: a multicenter prospective cohort study (daVinci study)
Abstract The safety and efficacy of non-vitamin K oral anticoagulant (NOAC) compared with warfarin in treating patients with non-valvular atrial fibrillation (NVAF) who developed acute ischemic stroke or transient ischemic attack (AIS/TIA), particularly those receiving tissue-plasminogen activator (tPA) therapy, remains unclear. Between April 2012 and December 2014, we conducted a multicenter prospective cohort study to assess the current clinical practice for treating such patients. We divided the patients into two groups according to the administration of oral anticoagulants (warfarin or NOACs) and tPA therapy. ...

Padua prediction score or clinical judgment for decision making on antithrombotic prophylaxis: a quasi-randomized controlled trial
In conclusion, the use of PPS was associated with a higher rate of appropriate thromboprophylaxis prescription; no significant differences were found in the other secondary outcomes. The use of PPS for the assessment of risk for VTE is associated with a reduced incidence of VTE compared with the clinical judgment. These result needs to be confirmed in future studies.

Thrombelastography does not predict clinical response to rtPA for acute ischemic stroke
Abstract Thrombelastography (TEG) measures coagulation in venous blood. We hypothesized that TEG, by reflecting clot subtype and ex vivo fibrinolysis, might predict fibrinolytic response to tPA as reflected by rapid clinical improvement or hemorrhagic transformation of the infarct. 171 acute ischemic stroke patients treated with tPA were prospectively enrolled. Venous blood for TEG was drawn before and 10 min after tPA bolus. We measured rapid clinical improvement (RCI = 8 point improvement on NIHSS or total NIHSS of 0, 1 at 36 h), Hemorrhagic transformation (HT = any blood on imaging within 36 h), and hyp...

Intravenous heparin dosing strategy in hospitalized patients with atrial dysrhythmias
Abstract Patients with non-valvular atrial fibrillation (AF) have an elevated stroke risk that is 2–7 times greater than in those without AF. Intravenous unfractionated heparin (UFH) is commonly used for hospitalized patients with atrial fibrillation and atrial flutter (AFL) to prevent stroke. Dosing strategies exist for intravenous anticoagulation in patients with acute coronary syndromes and venous thromboembolic diseases, but there are no data to guide providers on a dosing strategy for intravenous anticoagulation in patients with AF/AFL. 996 hospitalized patients with AF/AFL on UFH were evaluated. Bolus dosi...

Laboratory assessment of anti-thrombotic therapy in heart failure, atrial fibrillation and coronary artery disease: insights using thrombelastography and a micro-titre plate assay of thrombogenesis and fibrinolysis
Abstract As heart failure, coronary artery disease and atrial fibrillation all bring a risk of thrombosis, anti-thrombotic therapy is recommended. Despite such treatment, major cardiovascular events such as myocardial infarction and stroke still occur, implying inadequate suppression of thrombus formation. Accordingly, identification of patients whose haemostasis remains unimpaired by treatment is valuable. We compared indices for assessing thrombogenesis and fibrinolysis by two different techniques in patients on different anti-thrombotic agents, i.e. aspirin or warfarin. We determined fibrin clot formation and f...

Ancrod revisited: viscoelastic analyses of the effects of Calloselasma rhodostoma venom on plasma coagulation and fibrinolysis
Abstract Fibrinogen depletion via catalysis by snake venom enzymes as a therapeutic strategy to prevent or treat thrombotic disorders was utilized for over four decades, with ancrod being the quintessential agent. However, ancrod eventually was found to not be of clinical utility in large scale stroke trial, resulting in the eventual discontinuation of the administration of the drug for any indication. It was hypothesized that ancrod, possessing thrombin-like activity, may have unappreciated robust coagulation kinetics. Using thrombelastographic methods, a comparison of equivalent tissue factor initiated thrombin ...

Severity and outcomes according to stroke etiology in patients under 50 years of age with ischemic stroke
Abstract To analyze the association of stroke etiological subtypes with severity and outcomes at 3 and 12 months in patients ≤50 years. Observational study of patients admitted to a stroke unit (2007–2013). Variables: demographic data, vascular risk factors, comorbidities, severity on admission (NIHSS), and good functional outcome (mRS ≤ 1) at 3 and 12 months. We used multivariate analyses to evaluate the influence of stroke etiology on severity and outcomes. We included 214 patients, 58.3 % men, mean age 41.4 years. General linear models showed all etiologies were more severe than lacunar strokes (PÂ...

Why develop antidotes and reversal agents for non-vitamin K oral anticoagulants?
Abstract Over the past several years, non-vitamin K oral anticoagulants (NOACs) have been introduced into clinical practice for the treatment of venous thromboembolism and prevention of stroke in patients with nonvalvular atrial fibrillation. Clinical trials have shown these agents to have similar or less risk of major bleeding as compared to warfarin therapy. Moreover, when patients do experience a major bleeding event administration of advanced factor products is rare, and post-bleed outcomes are similar in those receiving a NOAC compared to those receiving warfarin. However, there are situations where urgent r...
