Prognostic impact of heart rate during atrial fibrillation on clinical outcomes in elderly non-valvular atrial fibrillation patients: ANAFIE Registry sub-cohort study
CONCLUSIONS: Elderly Japanese patients with non-paroxysmal NVAF and a heart rate ≥110 bpm have an increased risk of cardiac events. There was no interaction between heart rate category and the relative risk of adverse clinical events in patients taking DOACs compared with those taking warfarin.PMID:36427691 | DOI:10.1016/j.jjcc.2022.11.011

Differences and time trends in drug treatment of atrial fibrillation in men and women and doctors' adherence to warfarin therapy recommendations
Source: European Journal of Clinical Pharmacology Area: Evidence > Medicines Management > References Background: Little is known about prescription trends in atrial fibrillation (AF) in primary health care in Sweden. Objective: The aim was to study time trends in pharmacotherapy, in men and women with AF.  We also aimed at studying doctors' adherence to CHADS2 for prescribing warfarin.  CHADS2 assesses stroke risk by presence of known risk factors, i.e. congestive heart failure, hypertension, age over 75 years, diabetes, previous stroke and transient ischaemic attack. Methods: Data were obtained from...

Abstract 25: Predicting Outcomes among Patients with Heart Failure Receiving Anticoagulation with Warfarin Concurrent III Session A: Oral Abstract Presentations on EHS & Health IT
Conclusion: We developed a composite score for CHF severity which predicted both anticoagulation control and the rate of major hemorrhage among patients anticoagulated with warfarin. This study suggests that relatively easily observable characteristics can be used to risk-stratify patients with CHF who are receiving anticoagulation for AF.

Causes of Death and Influencing Factors in Patients with Atrial Fibrillation: A Competing Risk Analysis from the Randomized Evaluation of Long-Term Anticoagulant Therapy Study.
CONCLUSIONS: The majority of deaths are not related to stroke in a contemporary anticoagulated AF population. These results emphasize the need to identify interventions beyond effective anticoagulation, in order to further reduce mortality in AF.

Early Adoption of Dabigatran and Its Dosing in US Patients With Atrial Fibrillation: Results From the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation Health Services and Outcomes Research
Conclusions Patients receiving dabigatran were younger and at a lower risk of stroke and bleeding. Patients appeared to drive switching from warfarin, whereas clinical characteristics influenced de novo start of dabigatran. These data suggest cautious early uptake of dabigatran, and more careful attention to dosing adjustments is warranted. Clinical Trial Registration URL: Clinicaltrials.gov. Unique identifier: NCT01165710.

Anticoagulation versus placebo for heart failure in sinus rhythm.
CONCLUSIONS: Based on the two major randomised trials (HELAS 2006; WASH 2004), there is no convincing evidence that oral anticoagulant therapy modifies mortality or vascular events in patients with heart failure and sinus rhythm. Although oral anticoagulation is indicated in certain groups of patients with heart failure (for example those with atrial fibrillation), the available data does not support the routine use of anticoagulation in heart failure patients who remain in sinus rhythm.

Poor adherence to anticoagulation guidelines in patients with non-valvular atrial fibrillation treated in a tertiary cardiology unit
Conclusions Few patients who require anticoagulation receive it in accordance with the guidelines even in a tertiary cardiology unit. There are many impediments to the effective use of VKA for stroke prevention among patients with AF.

Stability of High-Quality Warfarin Anticoagulation in a Community-Based Atrial Fibrillation Cohort: The Anticoagulation and Risk Factors in Atrial Fibrillation (ATRIA) Study Epidemiology
Conclusions Nearly 60% of AF patients with high-quality TTR1 on warfarin maintained TTR ≥70% over the next 6 months. A minority deteriorated to very poor TTR. Patient features did not strongly predict TTR in the second 6-month period. Our analyses support watchful waiting for AF patients with initial high-quality warfarin anticoagulation before considering alternative anticoagulants.

Improved persistence with non-vitamin K oral anticoagulants compared with warfarin in patients with atrial fibrillation: recent Australian experience.
CONCLUSIONS: Persistence with NOAC drugs in patients with AF appears to be superior to warfarin. If continued long-term, this alone will be of clinical importance in the prevention of stroke and death. PMID: 27463735 [PubMed - as supplied by publisher]

Antiplatelet versus anticoagulation treatment for patients with heart failure in sinus rhythm.
CONCLUSIONS: There is evidence from RCTs to suggest that neither oral anticoagulation with warfarin or platelet inhibition with aspirin is better for mortality in systolic heart failure with sinus rhythm (high quality of the evidence for all-cause mortality and moderate quality of the evidence for non-fatal cardiovascular events and major bleeding events). Treatment with warfarin was associated with a 20% reduction in non-fatal cardiovascular events but a twofold higher risk of major bleeding complications (high quality of the evidence). We saw a similar pattern of results for the warfarin versus clopidogrel comparison (lo...

Registry of Japanese patients with atrial fibrillation focused on anticoagulant therapy in the new era: The RAFFINE registry study design and baseline characteristics.
CONCLUSION: The RAFFINE registry at baseline described the current status of anticoagulation therapy in Japan and long-term follow-up data will identify how outcomes vary between stratified groups in patients with AF in the DOAC era (UMIN Clinical Trials Registry UMIN000009617).

Abstract 175: Atrial Fibrillation in the USF Resident Clinics: Quality-Driven Medical Therapy Session Title: Poster Session AM
Patients with atrial fibrillation (afib) have a high rate of serious complications including stroke and decompensated heart failure. While patients with afib are five times more likely to suffer a stroke in their lifetime than the general population, this risk can be reduced by 64% with appropriate anticoagulation using warfarin or approved novel oral anticoagulants (NOACs). Reducing the morbidity and mortality from excess strokes is a common interest nationwide due to unsustainable healthcare costs, increasing human resource gaps in medicine, and payment reforms that hold physicians and healthcare organizations financiall...
