Atrial fibrillation (AF) is a major risk factor for ischemic stroke and associated with a 5-fold higher risk of stroke. In this retrospective cohort study, the incidence of and risk factors for ischemic stroke in patients with AF were identified. All patients (≥30 years old) without previous stroke who were diagnosed with AF in 2007-2013 were selected from the National Health Insurance Service-National Sample Cohort. To identify factors that influenced ischemic stroke risk, Cox proportional hazard regression analysis was conducted...

OBJECTIVE: To compare the risk and cost of stroke/systemic embolism (SE) and major bleeding between each direct oral anticoagulant (DOAC) and warfarin among non-valvular atrial fibrillation (NVAF) patients. METHODS: Patients (≥65 years) initiating warfarin or DOACs (apixaban, rivaroxaban, and dabigatran) were selected from the Medicare database from 01/01/2013-12/31/2014. Patients initiating each DOAC were matched 1:1 to warfarin patients using propensity score matching to balance demographics and clinical characteristics...

The effectiveness of oral anticoagulation therapy with warfarin (a vitamin K antagonist) in the treatment of thromboembolic disease, including stroke prophylaxis in patients with atrial fibrillation is well recognised. However, warfarin has a narrow therapeutic window and an unpredictable anticoagulation response, which make it difficult to achieve and maintain optimal anticoagulation. Various dietary factors, including sudden changes in eating patterns, can significantly alter anticoagulation control, thereby potentially exposing patients to the risk of bleeding or thromboembolic complications...

Anticoagulation, reducing the risk of thromboembolic events in patients undergoing cardioversion, is a cornerstone of peri-cardioversion management in patients with atrial fibrillation. We aimed to analyse published data on the efficacy and safety of direct oral anticoagulants (DOACs) in patients undergoing cardioversion. We performed a systematic review of randomized prospective clinical trials (RCTs) comparing DOACs with warfarin and reporting data on post-cardioversion outcomes of interest. Outcomes of interest were stroke, systemic thromboembolic events and major bleeding...

Andreea D Ceornodolea, Roland Bal, Johan L Severens
In Europe, 1-3% of the population suffers from atrial fibrillation (AF) and has increased stroke risk. By 2060 a doubling in number of cases and great burden in managing this medical condition are expected. This paper offers an overview of data on epidemiology and management of AF and stroke in four European countries as well as the interconnection between these dimensions. A search index was developed to access multiple scientific and "grey" literatures. Information was prioritised based on strength of evidence and date...

OBJECTIVES: Exclusion of the left atrial appendage has been proposed to reduce the risk of stroke in patients with atrial fibrillation. The aim of this study was to evaluate the feasibility and efficacy of the AtriClip PRO·V device (AOD2), now in development, for left atrial appendage exclusion in a canine model. METHODS: The newest AtriClip design comprises a dual-spring mechanism that allows the clip to open into a 'V' shape while still providing equivalent force along the length of the beam...

INTRODUCTION: Detection of atrial fibrillation (AF) is important given the risk of complications, such as stroke and heart failure, and the need for preventive measures. Detection is complicated because AF can be silent or paroxysmal. Describing current practice may give clues to improve AF detection. The aim of this study was to describe how cardiologists currently detect AF. METHODS: Between December 2014 and May 2015, we sent Dutch cardiologists an online questionnaire...

Subjects carrying the C2238 variant of the atrial natriuretic peptide (ANP) gene have a higher occurrence of stroke and acute coronary syndrome, suggesting an increased predisposition to acute thrombotic events in these subjects. We evaluated for the first time the direct effects of mutant ANP (C2238/αANP) on platelet activation in vitro and in human subjects. In vitro, platelets were incubated with no peptide, with T2238/αANP (WT) or with C2238/αANP at different concentrations. C2238/αANP (10(-10) M) induced higher collagen-induced platelet aggregation with respect to both control without ANP and T2238/αANP...

BACKGROUND: Atrial fibrillation (AF) is a common cardiac arrhythmia that increases the risk of thromboembolic events. Anticoagulation therapy to prevent AF-related stroke has been shown to be cost-effective. A national screening programme for AF may prevent AF-related events, but would involve a substantial investment of NHS resources. OBJECTIVES: To conduct a systematic review of the diagnostic test accuracy (DTA) of screening tests for AF, update a systematic review of comparative studies evaluating screening strategies for AF, develop an economic model to compare the cost-effectiveness of different screening strategies and review observational studies of AF screening to provide inputs to the model...

BACKGROUND: Preliminary evidence suggests statins may reduce major perioperative vascular events. However, evidence is limited to observational studies, underpowered trials, and non-comprehensive systematic reviews. This review aims to assess the effects of perioperative statin use on cardiovascular complications in patients submitted to non-cardiac surgery. METHODS: We will search MEDLINE/PubMed, EMBASE, LILACS, CENTRAL, Web of Science, and CINAHL for randomized controlled trials assessing the effects of perioperative statin use in adults undergoing non-cardiac surgery and reporting cardiovascular complications...

Bronwyn C Thorp, Xavier Badoux
Ibrutinib is a Bruton's tyrosine kinase (BTK) inhibitor finding increasingly widespread use in non-Hodgkin lymphoma. Evidence of an increased risk of atrial fibrillation (AF) emerged in Phase III studies with a median incidence of approximately 6%. The mechanism remains unknown, but inhibition of a cardioprotective pathway has been proposed. Ibrutinib induces a platelet function defect, increasing the bleeding risk of anticoagulation for AF stroke prophylaxis. Multiple potential drug interactions are an added complication...

BACKGROUND AND PURPOSE: Abnormal P-wave axis (aPWA) has been linked to incident atrial fibrillation and mortality; however, the relationship between aPWA and stroke has not been reported. We hypothesized that aPWA is associated with ischemic stroke independent of atrial fibrillation and other stroke risk factors and tested our hypothesis in the ARIC study (Atherosclerosis Risk In Communities), a community-based prospective cohort study. METHODS: We included 15 102 participants (aged 54...

BACKGROUND: Atrial fibrillation (AF) ablation procedures are increasingly being performed in patients receiving direct oral anticoagulants (DOACs). Experience regarding the safety of edoxaban in this context is limited. In an exploratory analysis we therefore investigated the outcome of patients undergoing transcatheter AF ablation in the ENGAGE AF-TIMI 48 trial. METHODS & RESULTS: During the trial, 193 transcatheter AF ablation procedures were performed in 169 patients...

BACKGROUND: Oral anticoagulants (OACs) reduce stroke risks with nonvalvular atrial fibrillation (AF); however, they are underused because of absolute or relative contraindications due to real or perceived risk of bleeding. Although left atrial appendage closure is increasingly performed in OAC-ineligible patients, this has not been studied in a randomized controlled trial. STUDY OBJECTIVES: The ASAP-TOO study is designed to establish the safety and effectiveness of the Watchman left atrial appendage closure device in patients with nonvalvular AF who are deemed ineligible for OAC...

BACKGROUND: Device-detected subclinical atrial fibrillation (AF) refers to infrequent, short-lasting, asymptomatic AF that is detected only with long-term continuous monitoring. Subclinical AF is common and associated with an increased risk of stroke; however, the risk of stroke with subclinical AF is lower than for clinical AF, and very few patients with subclinical AF alone have been included in large AF anticoagulation trials. The net benefit of anticoagulation in patients with subclinical AF is unknown...

BACKGROUND: Isolated distal deep venous thrombosis (IDDVT) is a common complication after ischemic stroke. However, there is a paucity of evidence regarding the clinical features and risk factors of IDDVT in patients with acute ischemic stroke. This study aimed to establish and validate a clinical prediction scale of IDDVT at an early stage of ischemic stroke development. METHODS: We retrospectively studied consecutive patients with stroke admitted to our neurology department between January and December 2016...
