Non-Vitamin K Oral Anticoagulants (NOACs) for stroke prevention in Asian patients with atrial fibrillation: Time for a reappraisal
Non-Vitamin K Antagonist Oral Anticoagulants (NOACs) have changed the landscape for stroke prevention in atrial fibrillation (AF). Given the huge burden of AF in Asians, more attention to stroke prevention is clearly needed. Aiming to provide an overview and reappraisal of stroke prevention in Asians with AF, we searched MEDLINE for information on NOACs in Asians. In addition, abstracts from national and international cardiovascular meetings were studied to identify unpublished studies.In the 4 recent Phase 3 trials comparing NOACs to warfarin, a consistent pattern is evident.

Warfarin and Aspirin Use for Stroke Prevention Among Patients With Atrial Fibrillation: The US National Health and Wellness Survey
This study examined VKA and ASA use and their clinical correlates, including CHADS2 stroke risk scores, among adult patients with AF in the general population. Participants included 1290 (1.72%) adults reporting diagnosis with AF (mean age, 64.9 years; 65% men) from the 2009 US National Health and Wellness Survey, an online, self-administered, nationwide, stratified random sample survey of 75,000 adults. Antithrombotic use patterns, including VKA, ASA, VKA+ASA, and non-VKA/ASA, and their correlates were examined using logistic regressions. Respondents with AF were treated with VKA (26.6%), ASA (34.5%), VKA+ASA (15.4%), or ...

Smoking, atrial fibrillation, and ischemic stroke: a confluence of epidemics
Purpose of review: Smoking and atrial fibrillation are major contemporary health concerns. They commonly coexist and are frequent causes of ischemic stroke. The purpose of this article is to describe recent scientific investigations about smoking, atrial fibrillation, and ischemic stroke, with a primary focus on prevention. Recent findings: Smoking predisposes to atrial fibrillation and is useful for the prediction of future atrial fibrillation. Several recent risk prediction models for adverse events associated with atrial fibrillation include smoking as a component. Smoking status identifies patients at high risk of inci...

The Indian consensus guidance on stroke prevention in atrial fibrillation: An emphasis on practical use of nonvitamin K oral anticoagulants.
Abstract The last ten years have seen rapid strides in the evolution of nonvitamin K oral anticoagulants (NOACs) for stroke prevention in patients with atrial fibrillation (AF). For the preparation of this consensus, a comprehensive literature search was performed and data on available trials, subpopulation analyses, and case reports were analyzed. This Indian consensus document intends to provide guidance on selecting the right NOAC for the right patients by formulating expert opinions based on the available trials and Asian/Indian subpopulation analyses of these trials. A section has been dedicated to the curren...

The Educational Needs of Clinicians Regarding Anticoagulation Therapy for Prevention of Thromboembolism and Stroke in Patients With Atrial Fibrillation
The objective is to identify practice patterns and attitudes of and barriers faced by US physicians assessing thromboembolism/stroke risk and managing anticoagulation in atrial fibrillation (AF) to determine educational needs. Case-based surveys were used to assess practice patterns, guideline use, barriers, and attitudes; 51 cardiologists and 50 primary care physicians (PCPs) were surveyed. Most cardiologists use validated risk scoring systems to assess thromboembolism/stroke risk, and more than half of PCPs use clinical experience. Assessment of bleeding risk varied; more than half of respondents rely on clinical judgmen...

Cost-effectiveness analysis of apixaban versus acetylsalicylic acid in the prevention of stroke in patients with non-valvular atrial fibrillation in Spain.
CONCLUSIONS: According to this model, when costs and estimated lifetime outcomes achieved with apixaban are compared with those of ASA, apixaban was assessed to be a cost-effective treatment for the prevention of stroke in patients with NVAF in Spain.

Atrial Fibrillation and Stroke
Atrial fibrillation (AF) is the most prevalent heart rhythm disorder. AF accounts for a great proportion of deaths because it independently increases all-cause mortality and cardiovascular mortality risks. Ischemic stroke is the most common cardiovascular adverse event in AF patients. Oral anticoagulation (OAC) therapy with vitamin K antagonists (VKA) has been central for stroke prevention. Several drugs with a direct inhibitory effects on thrombin and factor Xa have been developed. These non-vitamin K antagonist oral anticoagulants (NOACs) are as effective and safer than warfarin. This review provides an overview of curre...

Cause of Death and Predictors of All-Cause Mortality in Anticoagulated Patients With Nonvalvular Atrial Fibrillation: Data From ROCKET AF Arrhythmia and Electrophysiology
Conclusions In a large population of patients anticoagulated for nonvalvular atrial fibrillation, 7 in 10 deaths were cardiovascular, whereas <1 in 10 deaths were caused by nonhemorrhagic stroke or systemic embolism. Optimal prevention and treatment of heart failure, renal impairment, chronic obstructive pulmonary disease, and diabetes may improve survival.

Safety and efficacy of non-vitamin K oral anticoagulant treatment compared with warfarin in patients with non-valvular atrial fibrillation who develop acute ischemic stroke or transient ischemic attack: a multicenter prospective cohort study (daVinci study)
Abstract The safety and efficacy of non-vitamin K oral anticoagulant (NOAC) compared with warfarin in treating patients with non-valvular atrial fibrillation (NVAF) who developed acute ischemic stroke or transient ischemic attack (AIS/TIA), particularly those receiving tissue-plasminogen activator (tPA) therapy, remains unclear. Between April 2012 and December 2014, we conducted a multicenter prospective cohort study to assess the current clinical practice for treating such patients. We divided the patients into two groups according to the administration of oral anticoagulants (warfarin or NOACs) and tPA therapy. ...

PM198 Antithrombotic Treatment in Relation to Age and Stroke Risk in Patients With Newly Diagnosed Atrial Fibrillation (Gloria-AF Phase II)
Vitamin K antagonists (VKAs) or the non-VKA oral anticoagulants (NOACs) are recommended for prevention of stroke in patients with atrial fibrillation (AF) and additional stroke risk factors. Phase II of the Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation (GLORIA-AF) started after approval of dabigatran etexilate, the first NOAC available for stroke prevention in patients with AF.

Frequency and Determinants of Adherence to Oral Anticoagulants in Stroke Patients with Atrial Fibrillation in Clinical Practice
Background: Vitamin K antagonists (VKAs) and non-VKA oral anticoagulants (NOACs) are beneficial in patients with stroke and atrial fibrillation (AF). However, little is known about frequency and determinants of adherence to NOACs/VKAs in clinical practice.Methods: This is a single-center explorative study from the Novel Oral Anticoagulants in Stroke Patients (NOACISP)-LONGTERM registry. We included consecutive AF-stroke patients treated with NOACs/VKAs and followed up for 3-24 months. Adherence was assessed at follow-up using structured interviews and quantified as the proportion of prescribed doses taken (PDT). Outcome me...

Early real-world evidence of persistence on oral anticoagulants for stroke prevention in non-valvular atrial fibrillation: a cohort study in UK primary care
Conclusions Observed differential prescribing of OACs can result in channelling bias in comparative effectiveness research. Persistence patterns changed over follow-up time, but there are indications of improved persistence rates with apixaban over other OACs in the UK. A larger study with longer follow-up is needed to corroborate findings. This study is registered on ClinicalTrials.gov (NCT02488421).
