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. ...

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...

Delayed diagnosis of congenital thrombotic thrombocytopenic purpura in a patient with recurrent strokes
AbstractCongenital thrombotic thrombocytopenic purpura (cTTP) is caused by ADAMTS13 mutations and associated with high risk of microvascular thrombosis. A 58  year old female had an ischemic stroke during hormonal fertility, and a TIA a year after. She suffered another stroke 18 years later while on warfarin. Four months after she developed severe thrombocytopenia, mild anemia, and increased LDH. Blood film showed schistocytes. She was hospitalized wit h presumptive TTP. ADAMTS 13 activity was undetectable without inhibitor. She developed another stroke and received plasma exchange. A homozygote ADAMTS 13 mutation was id...

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...

Effectiveness and safety of non-vitamin-K antagonist oral anticoagulants versus warfarin in atrial fibrillation patients with thrombocytopenia
AbstractPatients with thrombocytopenia were excluded from major clinical trials that investigated non-vitamin-K antagonist oral anticoagulants (NOACs) for stroke prevention in atrial fibrillation (AF). The aim of this study was to evaluate the effectiveness and safety of NOAC versus warfarin in AF patients with thrombocytopenia. From 2010 to 2017, a cohort study based on electronic medical records of a multi-center healthcare provider in Taiwan and included 8239 anticoagulated AF patients (age 77.0  ± 7.3 years, 48.0% female). Patients were divided into two subgroups: 7872 patients with a normal platelet count and 36...

Practical aspects of treatment with target specific anticoagulants: initiation, payment and current market, transitions, and venous thromboembolism treatment
Abstract Target specific anticoagulants (TSOACs) have recently been introduced to the US market for multiple indications including venous thromboembolism (VTE) prevention in total hip and knee replacement surgeries, VTE treatment and reduction in the risk of stroke in patients with non-valvular atrial fibrillation (NVAF). Currently, three TSOACs are available including rivaroxaban, apixaban, and dabigatran with edoxaban currently under Food and Drug Administration review for VTE treatment and stroke prevention in NVAF. The introduction of these agents has created a paradigm shift in anticoagulation by considerably...

Patient-reported health preferences of anticoagulant-related outcomes
This study aimed to use direct measures to elicit patient-reported utilities (i.e., preferences) for anticoagulant-related outcomes. A cross-sectional survey was administered to 100 patients taking warfarin in an anticoagulation clinic. Utilities for six long-term and four short-term anticoagulant-related health states were elicited by the visual analogue scale (VAS) and standard gamble (SG) methods. Health states with the highest SG-derived mean utility values were “well on rivaroxaban” (mean ± SD = 0.90 ± 0.15), “well on warfarin” (0.86 ± 0.17), and “well on dabigatran” (0.83 ± 0.18). Approximat...

Decision-making about the use of non-vitamin K oral anticoagulant therapies for patients with atrial fibrillation
Abstract Until recently, vitamin K antagonists, warfarin being the most commonly used agent in the United States, have been the only oral anticoagulant therapies available to prevent stroke in patients with atrial fibrillation (AF). In the last 5 years four new, non-vitamin K oral anticoagulants, the so-called NOACs or novel oral anticoagulants, have come to market and been approved by the Federal Drug Administration. Despite comparable if not superior efficacy in preventing AF-related stroke, and generally lower risks of major hemorrhage, particularly intracranial bleeding, the uptake of these agents has been s...
