Systematic Review and Meta-Analysis of Direct Oral Anticoagulants Versus Warfarin in Atrial Fibrillation With Low Stroke Risk
Oral anticoagulation (OAC) in patients with atrial fibrillation (AF) has been shown to prevent thromboembolic complications, but concerns about the increased risk of major bleeding warrant judicious consideration of the risks and benefits.1 Current guidelines recommend OAC prescription for patients with AF at high risk of stroke, as measured by CHA2DS2-VASc scores of ≥2 and ≥3 in men and women respectively.2–4 Men and women with scores of 1 and 2 respectively (i.e., a single nongender-related stroke risk factor) are deemed to be at low-moderate risk of stroke and OAC prescription may be considered to reduce thromboem...

Screening for Asymptomatic Atrial Fibrillation While Monitoring the Blood Pressure at Home: Trial of Regular Versus Irregular Pulse for Prevention of Stroke (TRIPPS 2.0)
In conclusion, home screening for asymptomatic AF while taking BP measurements can be performed accurately. This can be used to detect new AF, allowing treatment with anticoagulation to reduce the future risk for stroke.

How Well do Stroke Risk Scores Predict Hemorrhage in Patients with Atrial Fibrillation?
The decision to use anticoagulants for atrial fibrillation depends on comparing a patient’s estimated risk of stroke to their bleeding risk. Several of the risk factors in the stroke risk schemes such as overlap with hemorrhage risk. We compared how well two stroke risk scores (CHADS2 and CHA2DS2-VASc) and two hemorrhage risk scores (the ATRIA bleeding score and the HAS-BLED score) predicted major hemorrhage on and off warfarin in a cohort of 13,559 community-dwelling adults with AF. Over a cumulative 64,741 person-years of follow up, we identified a total of 777 incident major hemorrhage events.

Relation of Risk of Stroke in Patients With Atrial Fibrillation to Body Mass Index (From Patients Treated With Rivaroxaban and Warfarin in the ROCKET AF Trial)
We investigated stroke outcomes in normal weight (body mass index [BMI] 18.50-24.99 kg/m2), overweight (BMI 25.00-29.99 kg/m2), and obese (BMI ≥30 kg/m2) patients with AF treated with rivaroxaban and warfarin. We compared the incidence of stroke and systemic embolic events (SEE) as well as bleeding events in normal weight (n=3289), overweight (n=5535), and obese (n=5206) patients in a post-hoc analysis of the ROCKET AF trial. Stroke and SEE rates per 100 patient-years were 2.93 in the normal weight group (reference group), 2.28 in the overweight group (adjusted hazard ratio [HR] 0.81, 95% confidence interval [CI]: 0.66-0...

Relation of Stroke and Bleeding Risk Profiles to Efficacy and Safety of Edoxaban for Cardioversion of Atrial Fibrillation (From the Edoxaban Versus Warfarin in Subjects Undergoing Cardioversion of Atrial Fibrillation ENSURE-AF Study)
In the ENSURE-AF study, edoxaban was compared to enoxaparin –warfarin in patients undergoing electrical cardioversion of nonvalvular atrial fibrillation, showing comparable low rates of bleeding and thromboembolism. This ancillary analysis investigated differences in relation to stroke and bleeding risk profiles. Secondly, we determined clinical risk profi les to quality of anticoagulation control in the warfarin arm. Primary efficacy (composite of stroke, systemic embolic event, myocardial infarction, and cardiovascular death) and safety (composite of major and clinically relevant nonmajor bleeding) outcomes and time to...

Thoracoscopic Left Atrial Appendage Occlusion for Stroke Prevention Compared with Long-Term Warfarin Therapy in Patients With Nonvalvular Atrial Fibrillation
Thoracoscopic left atrial appendage (LAA) occlusion is an alternative treatment for stroke prevention in patients with atrial fibrillation. Prospective study comparing thoracoscopic LAA occlusion and warfarin therapy is still lacking. The goal of this prospective cohort study was to assess the safety and efficacy of thoracoscopic LAA occlusion for stroke prevention in patients with nonvalvular atrial fibrillation (NVAF) compared with long-term warfarin therapy. 492 NVAF Patients were enrolled. 257 patients were treated with thoracoscopic LAA occlusion and 235 with long-term warfarin therapy.

Relation of the CHA2DS2-VASc Score to Risk of Thrombotic and Embolic Stroke in Community-Dwelling Individuals Without Atrial Fibrillation (From The Atherosclerosis Risk in Communities ARIC Study)
Recent hospital-based cohort studies found the CHA2DS2-VASc score to be associated with ischemic stroke in individuals without atrial fibrillation (AF). Our aim was to determine the distribution of embolic and thrombotic strokes and association with the CHA2DS2-VASc score, among community-dwelling individuals without AF. We included participants from the Atherosclerosis Risk in Communities (ARIC) Study who attended visit 4 (1996-98) and had no prior AF, stroke, or anticoagulant use (n=10,671). During follow-up through 2008, incident AF cases (n=760) and participants who started warfarin were censored.

Risk Stratification and Stroke Prevention Therapy Care Gaps in Canadian Atrial Fibrillation Patients (From the CO-ordinated National Network to Engage physicians in the Care and Treatment of patients with Atrial Fibrillation CONNECT AF Chart Audit)
The objectives of this national chart audit (January-June 2013) of 6346 AF patients (≥18 years without a significant heart valve disorder) from 647 primary care physicians were to: 1) Describe the frequency of stroke and bleed risk assessments in patients with non-valvular atrial fibrillation (AF) by primary care physicians, including the accuracy of these assessments relative to established predictive indices; 2) outline contemporary methods of anticoagulation used; and, 3) report the time in the therapeutic range amongst patients prescribed warfarin.

Effectiveness and Safety of Direct Oral Anticoagulants and Warfarin, Stratified by Stroke Risk in Patients with Atrial Fibrillation
The objective of the study was to examine how the comparative effectiveness and safety of direct oral anticoagulants (DOACs) and warfarin differ across subgroups of atrial fibrillation (AF) patients defined by stroke risk (CHA2DS2-VASc score ≤3, 4-5, ≥6). Using claims data from a 5% random sample of Medicare beneficiaries, we identified patients newly diagnosed with AF in 2013-2014 who initiated warfarin (n=12,354), apixaban (n=2,358), dabigatran (n=1,415) or rivaroxaban (n=5,139), and categorized them according to their CHA2DS2-VAS c score (≤3, 4-5, ≥6).

Relation of Race, Apparent Disability, and Stroke Risk With Warfarin Prescribing for Atrial Fibrillation in Patients Receiving Maintenance Hemodialysis
We examined patterns of warfarin use, and associated factors, after AF diagnosis. This retrospective cohort analysis studied US Medicare patients receiving maintenance dialysis January 1, 2008-June 30, 2010. Demographics, comorbidity, and a durable medical equipment claims-based disability proxy score predicted warfarin prescription after AF diagnosis. The analysis included 8964 patients with non-valvular AF.

Thoracoscopic Left Atrial Appendage Occlusion for Stroke Prevention Compared with Long-Term Warfarin Therapy in Patients With Nonvalvular Atrial Fibrillation
In their recent paper, Fu et al. conclude that thoracoscopic left atrial appendage (LAA) occlusion is superior to warfarin for a composite outcome of stroke, systemic embolism and mortality.1 We suggest considering their results with caution.
