Direct Oral Anticoagulants Versus Vitamin K Antagonists in Real-life Patients With Atrial Fibrillation. A Systematic Review and Meta-analysis

ConclusionsData from this meta-analysis suggest that, vs warfarin, the stroke prevention effectiveness and bleeding risk of direct oral anticoagulants may differ in real-life patients with atrial fibrillation.ResumenIntroducción y objetivosDeterminar la efectividad de los anticoagulantes orales directos frente a los antagonistas de la vitamina K en pacientes con fibrilación auricular de la práctica clínica.MétodosSe realizó una revisión sistemática acorde con los estándares metodológicos de Cochrane. Los resultados de la revisión se publicaron según la declaración PRISMA. Se empleó la herramienta ROBINS-I para determinar el riesgo de sesgos.ResultadosSe incluyeron datos de 27 estudios diferentes provenientes de 30 publicaciones. En los estudios con seguimiento hasta 1 año, el apixabán (HR = 0,93; IC95%, 0,71-1,20) y dabigatrán (HR = 0,95; IC95%, 0,80-1,13) no se redujo significativamente el riesgo de ictus isquémico frente a la warfarina, pero sí el rivaroxabán (HR = 0,83; IC95%, 0,73-0,94). Con respecto al riesgo de hemorragias mayores, el apixabán (HR = 0,66; IC95%, 0,55-0,80) y el dabigatrán (HR = 0,83; IC95%, 0,70-0,97) lo redujeron significativamente frente a la warfarina, pero no el rivaroxabán (HR = 1,02, IC95%, 0,95-1,10), aunque con he...

Non –vitamin K antagonist oral anticoagulants (NOACs), such as dabigatran, are widely used to prevent ischemic stroke in patients with nonvalvular atrial fibrillation. Nonetheless, stroke occurs in 1–2% of patients, and the use of NOACs may increase the bleeding risk for patients who are receiving a cute treatment of intravenous thrombolysis (IVT) or endovascular thrombectomy (EVT). Idarucizumab, a monoclonal antibody developed to bind dabigatran, has been proven safe and effective for patients with uncontrolled bleeding or for patients planning to receive emergent procedures.

We aimed to assess outcomes between dual antithrombotic therapy with DOACs plus an antiplatelet agent (Dual therapy) in comparison to warfarin plus two antiplatelet agents (Triple therap...

In conclusion, current published data suggest that th e use of reduced-dose NOACs is non-inferior to warfarin in patients with AF (in particular Asians).

AbstractStroke is ranked as the second leading cause of death worldwide. Ischemic stroke commonly results from emboli that originate in the heart among high-risk patients, such as those who develop atrial fibrillation. Yet, treatment is currently limited to anticoagulants, which may be associated with life-threatening bleeding. Our aim was to develop an alternative, device-based approach for continuous stroke prevention in high-risk patients. To this end, a novel endovascular tubular mesh was designed to be implanted in the aortic arch and to reroute emboli away from critical cerebral arteries. The feasibility of this appr...

This study evaluated and compared the safety outcomes of DOACs versus warfarin in patients with non-valvular AF and concomitant CKD. Patients in our health system with AF prescribed oral anticoagulants during 2010 to 2017 were identified. All-cause mortality, bleeding, and hemorrhagic and ischemic stroke were evaluated based on degree of renal impairment and method of anticoagulation.

AbstractThe role of non-vitamin K antagonist oral anticoagulants (NOACs) in stroke prevention remains unclear in Asian patients with atrial fibrillation (AF). Therefore, we performed a meta-analysis to compare the efficacy and safety outcomes of NOACs in Asian patients with AF from the real-world settings. The PubMed and Embase databases were systematically searched to identify eligible observational studies until June 2019. The odds ratios (OR) and 95% confidence intervals (CIs) were calculated and then pooled by a random-effects model. A total of 18 observational studies were included. Compared with warfarin, dabigatran ...

AbstractBackgroundInformation on subgroup assessments in systematic reviews (SR) of atrial fibrillation (AF) is limited. This review aims to describe subgroup analyses in AF SRs to inform the design of SRs and randomized trials as well as clinical practice.MethodsWe conducted a cross sectional meta-epidemiological study of Cochrane AF reviews by searching AF (including variants) in the title, abstract, or keyword field without date or language restrictions (Issue 9; September 2018). Two reviewers independently extracted study characteristics to summarize frequency of subgroups pre-specified and conducted and report credibi...

AbstractThe optimal management of oral anticoagulation (OAC) in the acute phase of non valvular atrial fibrillation (NVAF)-related acute ischemic stroke (AIS) remains controversial, especially in very old patients. Therefore, the aim of our study was to evaluate the practical management of OAC in this context. We conducted an observational retrospective study on patients 85-years old and older admitted to two Italian hospitals for NVAF-related AIS. For each patient, clinical and brain computed tomography data were recorded. Type of OAC (vitamin K antagonists, VKAs or Direct Oral Anticoagulants, DOACs), dosage and starting ...

CONCLUSIONS: The risks of ischemic stroke/SE and major bleeding were significantly higher in HIV-infected patients compared with non-HIV-infected patients with AF. Despite this, the actual use of OACs among AF patients with HIV was suboptimal. PMID: 31619594 [PubMed - as supplied by publisher]

CONCLUSIONS: Although the incidences of stroke/TIA, major bleeding, and death were relatively low among patients for whom OAC therapy was discontinued, stroke/TIA occurrence was strongly associated with a high baseline stroke risk rather than with OAC status. Thus, discontinuation of OAC therapy requires careful consideration, especially in patients with a high baseline stroke risk. PMID: 31619591 [PubMed - as supplied by publisher]
