Cardiovascular and renal outcomes in patients with atrial fibrillation and stage 4 –5 chronic kidney disease receiving direct oral anticoagulants: a multicenter retrospective cohort study
AbstractThe role of direct oral anticoagulants (DOAC) in patients with atrial fibrillation (AF) and stage 4 –5 chronic kidney disease (CKD) is controversial. Electronic medical records from 2012 to 2021 were retrieved for patients with AF and stage 4–5 CKD receiving oral anticoagulants. Patients were separated into those receiving DOACs (dabigatran, rivaroxaban, apixaban, or edoxaban) or vitamin K ant agonists (VKA). Primary outcomes included ischemic stroke (IS), systemic thrombosis (SE), major bleeding, gastrointestinal bleeding, hemorrhagic stroke, acute myocardial infarction, cardiovascular death, and all-cause dea...

Clinical impact of oral anticoagulation among octogenarians with atrial fibrillation and anaemia
AbstractOur study aimed to describe the efficacy and safety of oral anticoagulation (OAC) use in elderly patients (> or = 80 years-old) with atrial fibrillation (AF) and concomitant anaemia. Data for this study were sourced from AF Research Database (NCT03760874). AF patients aged ≥ 80 who received OAC treatment, both direct oral anticoagulant (DOAC) and vitamin K antagonist (VKA) were selected. Partici pants were categorized as anaemic and non-anaemic. The primary outcome was the occurrence of overall bleeding. The primary effectiveness outcome was the occurrence of thromboembolic events (a composite of isch...

Effectiveness and safety of oral anticoagulants in non-valvular atrial fibrillation patients with prior bleeding events: a retrospective analysis of administrative claims databases
ConclusionsIn this real-world analysis of a large sample of NVAF patients with prior bleeding, NOACs were associated with similar or lower risk of stroke/SE and MB vs. warfarin and variable risk of stroke/SE and MB against each other.

Relationship between temporal rhythm-based classification of atrial fibrillation and stroke: real-world vs. clinical trial
ConclusionsOverall, our results support the need for anticoagulation based on thromboembolic risk profile rather than AF type.

Oral anticoagulation patterns and prognosis in octogenarian patients with atrial fibrillation
In conclusion, in this cohort of post-discharge octogenarian patients with AF, the risk for all-cause death was similar in NOAC versus VKA users, after adjustment for baseline covariates. No differences in stroke and major bleeding events among these treatment groups were revealed.Graphic abstract

Oral anticoagulation for patients with atrial fibrillation in the ED: RE-LY AF registry analysis
AbstractOral anticoagulation (OAC) reduces stroke risk in patients with atrial fibrillation (AF). We sought to determine predictors of OAC initiation in AF patients presenting to the emergency department (ED). Secondary analysis of the RE-LY AF registry which enrolled individuals from 47 countries between 2007 and 2011 who presented to an ED with AF and followed them for 1 year. A total of 4149 patients with AF as their primary diagnosis who were not already taking OAC and had a CHA2DS2-VASc ≥ 1 for men or ≥ 2 for women were included in this analysis. Of these individuals, 26.8% were started on OAC (99.2% vi...

Short-term non-vitamin K antagonist oral anticoagulants vs. warfarin in preventing device-related thrombosis after left atrial appendage closure
AbstractUp to now we have had few evidences on the Non-vitamin K Antagonist Oral Anticoagulants (NOACs) ’ efficacy and safety in preventing device-related thrombosis (DRT) after percutaneous left atrial appendage closure (LAAC). After LAAC implantation, short-term anticoagulation (NOACs or warfarin) was prescribed. Baseline clinical characteristics, procedural parameters and postoperative follow up data were collected and compared between the two groups. From May 2014 to June 2018, 361 consecutive patients underwent LAAC implantation in our center. 170 patients received warfarin for 45 days at least after LAAC implantat...

Direct oral anticoagulants versus vitamin K antagonists in patients with atrial fibrillation and cancer a meta-analysis
ConclusionsIn comparison to VKA, DOACs were associated with a significant reduction of the rates of thromboembolic events and major bleeding complications in patients with AF and cancer. Further studies are needed to confirm our results.

Right drug, wrong dosage: insights from the PAVE-AF antithrombotic study in older patients with atrial fibrillation
AbstractOptimal antithrombotic treatment of older patients is usually impeded by several prevailing misconceptions. The aim of our study was to assess the type, dosage and predictors of antithrombotic therapy in older patients with non-valvular atrial fibrillation (NVAF). PAVE-AF was a prospective, cross-sectional study, including NVAF patients ≥ 80 years from 30 participating centers. Demographic data, comorbidities and treatment patterns were documented in a single visit. Patients treated with non-vitamin K oral anticoagulants (NOACs) were further classified into three dosing categories (recommended, underdosing and o...

Incidence and consequences of resuming oral anticoagulant therapy following hematuria and risks of ischemic stroke and major bleeding in patients with atrial fibrillation
In conclusion, more and more patients who suffer a hematuria while on oral anticoagulant therapy resume NOAC. Patients resuming NOAC have similar risks of ischemic stroke/systemic embolism and major bleeding compared with those resuming VKA.

Comparing the efficacy and safety of direct oral anticoagulants with vitamin K antagonist in cerebral venous thrombosis
AbstractCerebral venous thrombosis (CVT) causes significant disability and mortality. Current guidelines for CVT management support the initial use of unfractionated heparin or low molecular weight heparin followed by longer-term oral vitamin K antagonist (VKA). There has been increasing, albeit limited, evidence for the use of direct oral anticoagulants (DOAC) as an alternative to VKA. We performed a systematic review and meta-analysis of studies that compared the safety and efficacy of DOACs to VKA in treating CVT. A comprehensive literature search was carried out in Medline, Embase and Cochrane Stroke Group Trials Regis...

Non-vitamin K antagonist oral anticoagulants in patients with hypertrophic cardiomyopathy and atrial fibrillation: a systematic review and meta-analysis
AbstractSeveral studies have explored the use of NOACs compared with vitamin K antagonists (VKAs) in patients with hypertrophic cardiomyopathy (HCM) and atrial fibrillation (AF); and therefore, we aimed to compare the efficacy and safety outcomes of NOACs with VKAs in this population. We systematically searched the PubMed and Embase databases until August 5, 2019 for studies that compared the effect of NOACs with VKAs in patients with HCM and AF. The risk ratios (RRs) with 95% confidence intervals (CIs) were pooled using a random-effects model. A total of four observational studies were included in this meta-analysis. Over...

Thromboembolism and bleeding risk in atrial fibrillation ablation with uninterrupted anticoagulation between new oral anticoagulants and vitamin K antagonists: insights from an updated meta-analysis
In conclusions, uninterrupted NOACs was more effective than uninterrupted VKA in reducing major bleeding and pericardial effusion risk without increasing thromboembolism risk, and the benefits of uninterrupted NOACs on major bleeding complication could be more pronounced if CHA2DS2-VASc score ≥ 2 or target ACT > 300 s.

Management of oral anticoagulation in very old patients with non valvular atrial fibrillation related acute ischemic stroke
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 ...
