Systematic review and meta-analysis looks at risk factors for stroke in patients taking warfarin for AF
Source: Stroke Area: News The results of a systematic review and meta-analysis seeking to identify the risk factors that contribute to stroke risk in patients with atrial fibrillation (AF) who are taking an oral anticoagulant (OAC) have been published early online in the journal 'Stroke'.   The authors note that although OACs reduce the risks of stroke and mortality in patients with AF, some patients taking them will still sustain stroke.  They performed a systematic review to identify contemporary randomised clinical trials investigating OACs in patients with AF, and then performed a meta-analysis of recent...

Review of Economics and Cost-Effectiveness Analyses of Anticoagulant Therapy for Stroke Prevention in Atrial Fibrillation in the US.
CONCLUSIONS: This review identified several areas of uncertainty regarding the economic benefit of anticoagulants. The generalizability of cost-effectiveness results of anticoagulant therapy in AF based on clinical trial data must be confirmed by comparative effectiveness research conducted in the real-world setting.

Apixaban: A New Factor Xa Inhibitor for Stroke Prevention in Patients With Nonvalvular Atrial Fibrillation
Atrial fibrillation (AF) is an independent risk factor for ischemic stroke occurrence, severity, recurrence, and mortality. Anticoagulation therapy for the prevention of thromboembolism is critical in patients with AF who are at risk of stroke. Warfarin has been an efficacious anticoagulant for this purpose, but its use has been limited by frequent laboratory monitoring, drug interactions, unpredictable individual response, delayed onset of action, and bleeding. Apixaban is the second oral direct selective factor Xa inhibitor approved for the prevention of stroke/systemic embolism in patients with nonvalvular AF. It was si...

Stroke prevention in atrial fibrillation—An Asian stroke perspective
Despite relatively lower prevalence of atrial fibrillation (AF) in Asians (~1%) than in Caucasians (~2%), Asia has a much higher overall disease burden because of its proportionally larger aged population. For example, on the basis of reported age-adjusted prevalence rates and projected population figures in China, there will be an estimated 5.2 million men and 3.1 million women with AF older than 60 years by year 2050. Stroke is a disabling complication of AF that is of increasing cause for concern in Asians patients. Implementing consensus expert recommendations for managing stroke risk in patients with AF can considerab...

Stroke or Transient Ischemic Attack in Patients with Transvenous Pacemaker or Defibrillator and Echocardiographically Detected Patent Foramen Ovale.
CONCLUSIONS: In patients with endocardial leads, the presence of a PFO on routine echocardiography is associated with a substantially increased risk of embolic stroke/TIA. This finding suggests a role of screening for PFOs in patients who require CIEDs, if detected, PFO closure, anticoagulation, or non-vascular lead placement may be considered.

Selection of Warfarin or One of the New Oral Antithrombotic Agents for Long-Term Prevention of Stroke among Persons with Atrial Fibrillation
Opinion statement Atrial fibrillation (AF) is the most common sustained cardiac rhythm disorder, which can potentially increases the risk of stroke by five-fold, thus, resulting in high public healthcare burden. Stroke prevention is vital in the management of AF patients. Vitamin K antagonists (VKA, eg, warfarin) have been the mainstay treatment to prevent ischemic stroke and systemic thromboembolism in AF patients for several decades. Despite the efficacy of warfarin, its limitations have recently driven the advent of some new antithrombotic agents, the non-VKA oral anticoagulant (NOACs, including dabigatran, ri...

Stroke prevention in atrial fibrillation: an update on current management strategies.
Authors: Hall T, Stanton T, Wang WY, Ng AC Abstract Stroke attributed to atrial fibrillation (AF) confers significant morbidity and mortality. In the past, warfarin has been the only successful stroke prevention agent available. However, it is often underutilized due to its well-known limitations, leaving many patients without adequate stroke protection. The last decade has seen significant strides forward in the field of anticoagulation for AF. The development of several novel oral anticoagulants that have superior efficacy, improved safety profile and fixed doses without the need for regular monitoring make them ...

Underutilization of warfarin for stroke prophylaxis in patients with atrial fibrillation or atrial flutter in Korea.
CONCLUSIONS: A high portion of AF/AFL patients with CHADS2 score ≥2 were undertreated with warfarin. As ischemic stroke is one of the leading causes of death in Korea, a more aggressive approach to prevent stroke in patients with AF/AFL is required. PMID: 26242197 [PubMed - as supplied by publisher]

Time to Cost-Effectiveness Following Stroke Reduction Strategies in AF Warfarin Versus NOACs Versus LAA Closure
ConclusionsBoth NOACs and LAAC with the Watchman device were cost-effective relative to warfarin, but LAAC was also found to be cost-effective and to offer better value relative to NOACs. The results of this analysis should be considered when formulating policy and practice guidelines for stroke prevention in AF.

Temporal Trends in Ischemic Stroke and Anticoagulation Therapy for Nonvalvular Atrial Fibrillation: Impact of Diabetes
ConclusionsIschemic stroke declined and warfarin use increased similarly in Medicare patients with and without diabetes. Ischemic stroke rates were consistently higher in diabetes patients, validating the inclusion of diabetes in risk calculators. The population of Medicare patients with diabetes who did not receive warfarin deserves future attention. This article is protected by copyright. All rights reserved.

Factors Associated with Thrombolysis Outcome in Ischemic Stroke Patients with Atrial Fibrillation
In this study, we investigated factors that influence the effect of intravenous thrombolysis in these patients. Our results showed that thrombolysis was independently associated with a favorable outcome (P < 0.001) and did not influence the mortality of AF-related ischemic stroke, although it increased the risk of hemorrhage within 24 h after treatment. Risk factors for a poor outcome at admission were: heart failure (P = 0.045); high systolic pressure (P = 0.039); high blood glucose (P = 0.030); and a high National Institutes of Health Stroke Scale (NIHSS) score (P < 0.001). Moreover, high systolic pressur...

Abstract 203: Preventing Stroke in Patients With Atrial Fibrillation: A Review of Published Interventions to Aid Patient Decision Making Session Title: Abstract Poster Session II
Conclusion: Interventions designed to aid patient decision making around stroke prevention in AF improved a selection of patient-centered outcomes. Given the availability of multiple NOACs and an implantable device for stroke prevention in AF, there is a need to develop and evaluate new patient decision support tools.
