ObjectivesTo explore and reflect on the current anticoagulation therapy offered to patients with atrial fibrillation (AF), potential challenges and the future vision for oral anticoagulants for patients with AF and healthcare professionals in Ireland.DesignA multistakeholder focus group using a World Café approach.ParticipantsNine participants from academic, clinical and health backgrounds attended the focus group together with a facilitator.ResultsEnhanced patient empowerment; more effective use of technology and developing system-based medical care pathways would provide improved supports for AF management. The challenges in providing these include cost and access issues, the doctor–patient relationship and the provision of education. While consensus for developing evidence-based pathways to maximise efficiency and effectiveness of AF treatment was evident, it would require a shared vision between stakeholders of integrated care. The benefits of embracing technological advances for clinicians and patients were evident; however, clinicians indicate this can increase pressure on already stretched resources; coupled with institutional barriers (including scarce resources) arising from the complex nature of anticoagulation for patients with AF, which emerged strongly. Including the unpredictable nature of warfarin, hidden costs associated with monitoring, adverse clinical effects, different patient cohorts (including those prescribed anticoagulant for the first time vs those switching from warfarin to a new oral anticoagulant (NOAC)), non-adherence concerns and undesirable impacts on patients’ daily lives.ConclusionsWhile anticoagulation therapy for patients with AF using NOACs has been widely adopted and is diffusing into routine practice, significant operationalisation issues and barriers to effective treatment/management persist. The reflections reported in this study are a catalyst for future discussion and research.

Abstract Background Non-vitamin K antagonist (VKA) oral anticoagulants (NOACs) have substantially improved anticoagulation therapy for prevention of stroke and systemic embolism in patients with atrial fibrillation (AF), and available routine care data have so far broadly confirmed the safety of different NOACs in routine practice. However, such data for edoxaban are scarce, especially in extremely low and high body weight (BW). These extreme BWs may affect the bioavailability, distribution, and half-life of NOACs and, consequently, outcomes of treatment. Methods We analysed outcomes in normal-weight (BMI 18.5–25) vs overweight (BMI 25–30) and obese (BMI >30) patients enrolled into the ETNA-AF-Europe observational study (NCT02944019) collecting information on patients treated with edoxaban in 825 sites in 10 European countries. This snapshot analysis set includes data of 7,672 patients (56.3% of all enrolled patients) which have completed their 1-year follow-up visit (mean follow-up: 343.5 days). Results Median patient age was 74 years for all patients, 76 years for patients with a BMI 18.5–25 (group 1), 75 years for patients with BMI 25–30 (group 2), and 72 for patients with a BMI >30 (group 3). CrCl was 64 mL/min for patients with a BMI 18.5–25, 68 mL/min for patients with BMI 25–30, and 72 mL/min for patients with a BMI >30. The CHA2DS2-VASc (mean 3.1±1.38) and HAS-BLED (mean 2.5±1.10) score did not differ significantly between groups. As expected, diabetes and hypertension were significantly less prevalent in leaner patients and - accordingly - inversely correlated to age. There was no correlation between body weight and life-threatening bleeding (group 1: 0.28%; group 2: 0.40%; group 3: 0.14%). Also, stroke rates (group 1: 0.74%; group 2: 0.81%; group 3: 0.76%) did not differ between groups. Conclusion BMI, within the range here assessed, does not affect 1-year outcomes in European AF patients treated with edoxaban. Acknowledgement/Funding Daiichi Sankyo Europe GmbH, Munich, Germany

Pharmacological Cardioversion

The therapeutic dilemma between rhythm and rate control in the management of atrial fibrillation (AF) is still unresolved and electrical or pharmacological cardioversion (CV) frequently represents a useful strategy. The most recent guidelines recommend anticoagulation according to individual thromboembolic risk. Vitamin K antagonists (VKAs) have been routinely used to prevent thromboembolic events. Non-vitamin K antagonist oral anticoagulants (NOACs) represent a significant advance due to their more predictable therapeutic effect and more favorable hemorrhagic risk profile. In hemodynamically unstable patients, an emergency electrical cardioversion (ECV) must be performed. In this situation, intravenous heparin or low molecular weight heparin (LMWH) should be administered before CV. In patients with AF occurring within less than 48 h, synchronized direct ECV should be the elective procedure, as it restores sinus rhythm quicker and more successfully than pharmacological cardioversion (PCV) and is associated with shorter length of hospitalization. Patients with acute onset AF were traditionally considered at lower risk of thromboembolic events due to the shorter time for atrial thrombus formation. In patients with hemodynamic stability and AF for more than 48 h, an ECV should be planned after at least 3 weeks of anticoagulation therapy. Alternatively, transesophageal echocardiography (TEE) to rule out left atrial appendage thrombus (LAAT) should be performed, followed by ECV and anticoagulation for at least 4 weeks. Theoretically, the standardized use of TEE before CV allows a better stratification of thromboembolic risk, although data available to date are not univocal.

Efficacy And Safety

Diabetes mellitus (DM) represents an independent risk factor for chronic AF and is associated with unfavorable outcomes. We aimed to evaluate the efficacy and safety of direct oral anticoagulants (DOACs) in patients with atrial fibrillation (AF), with and without diabetes mellitus (DM), using a new risk index (RI) defined as: RI =Rate of EventsRate of Patients at Risk. In particular, an RI lower than 1 suggests a favorable treatment effect. We searched MEDLINE, MEDLINE In-Process, EMBASE, PubMed, and the Cochrane Central Register of Controlled Trials. The risk index (RI) was calculated in terms of efficacy (rate of stroke/systemic embolism (stroke SEE)/rate of patients with and without DM; rate of cardiovascular death/rate of patients with and without DM) and safety (rate of major bleeding/rate of patients with and without DM) outcomes. AF patients with DM (n = 22,057) and 49,596 without DM were considered from pivotal trials. DM doubles the risk index for stroke/SEE, major bleeding (MB), and cardiovascular (CV) death. The RI for stroke/SEE, MB, and CV death was comparable in patients treated with warfarin or DOACs. The lowest RI was in DM patients treated with Rivaroxaban (stroke/SEE, RI = 0.08; CV death, RI = 0.13). The RIs for bleeding were higher in DM patients treated with Dabigatran (RI110 = 0.32; RI150 = 0.40). Our study is the first to use RI to homogenize the efficacy and safety data reported in the DOACs pivotal studies against warfarin in patients with and without DM. Anticoagulation therapy is effective and safe in DM patients. DOACs appear to have a better efficacy and safety profile than warfarin. The use of DOACs is a reasonable alternative to vitamin-K antagonists in AF patients with DM. The RI can be a reasonable tool to help clinicians choose between DOACs or warfarin in the peculiar set of AF patients with DM.

Objectives To assess budget impact of the implementation of an anticoagulation clinic (AC) compared to usual care (UC), in patients with non-valvular atrial fibrillation (NVAF). Method A decision tree was designed to analyze the cost and events rates over a 1-year horizon. The patients were distributed according to treatment, 30% Direct Oral Anticoagulant (DOAC) regimens and the rest to warfarin. The thromboembolism and bleeding were derived from observational studies which demonstrated that ACs had important impact in reducing the frequency of these events compared with UC, due to higher adherence with DOACs and proportion of time in therapeutic range (TTR) with warfarin. Costs were derived from the transactional platform of Colombian government, healthcare authority reimbursement and published studies. The values were expressed in American dollars (USD). The exchanged rate used was COP $3.693 per dollar. Results During 1 year of follow-up, in a cohort of 228 patients there were estimated 48 bleedings, 6 thromboembolisms in AC group versus 84 bleedings, and 12 thromboembolisms events in patients receiving UC. Total costs related to AC were $126 522 compared with $141 514 in UC. The AC had an important reduction in the cost of clinical events versus UC ($52 085 vs $110 749) despite a higher cost of care facilities ($74 436 vs $30 765). A sensibility analysis suggested that in the 83% of estimations, the AC produced savings varied between $27 078 and $135 391. Conclusions This study demonstrated that AC compared with UC, produced an important savings in the oral anticoagulation therapy for patients with NVAF.

Abstract Introduction Anticoagulation therapy is central for the management of stroke in patients with non-valvular atrial fibrillation (NVAF). Persistence with oral anticoagulation is essential to prevent thromboembolic complications. Purpose To assess persistence levels of DOACs and look for possible predictors of treatment discontinuity in NVAF patients. Methods We performed a population-based retrospective cohort study in the Veneto Region (north-eastern Italy, about 5 million inhabitants) using the regional health system databases. Naïve patients initiating direct oral anticoagulants (DOACs) for stroke prevention in NVAF from July 2013 to September 2017 were included in the study. Patients were identified using Anatomical Therapeutic Chemical (ATC) codes, excluding other indications for anticoagulation therapy using ICD-9CM codes. Treatment persistence was defined as the time from initiation to discontinuation of the therapy. Baseline characteristics and comorbidities associated to the persistence of therapy with DOACs were explored by means of Kaplan-Meier curves and assessed through Cox regression. Results Overall, 17920 patients initiated anticoagulation with DOACs in the study period. Most patients were older than 74 years old, while gender was almost equally represented. Comorbidities included hypertension (72%), diabetes mellitus (17%), congestive heart failure (9%), previous stroke/TIA (20%), and prior myocardial infarction (2%). After one year, the persistence to anticoagulation treatment was 82.7%, while the persistence to DOAC treatment was 72.9% with about 10% of the discontinuations being due to switch to VKAs. On multivariate analysis, factors negatively affecting persistence were female gender, younger age (<65 years), renal disease and history of bleeding. Conversely, persistence was better in patients with hypertension, previous cerebral ischemic events, and previous acute myocardial infarction. Persistence to DOAC therapy Conclusion This real-world data show that within 12 months, one out of four anticoagulation-naïve patients stop DOACs, while one out of five patients stop anticoagulation. Efforts should be made to correct modifiable predictors and intensify patient education.

Introduction. In modern therapy of patients with atrial fibrillation, which belongs to the group particularly at risk of stroke, prophylactic anticoagulation is of primary importance. The initiation and subsequent proper monitoring of long-term anticoagulation therapy is very important for this group of patients. The use of oral anticoagulants significantly reduces the risk of ischemic stroke, and thus ensures longer survival and avoidance of permanent disability among patients with atrial fibrillation. Aim. Assessment of the level of knowledge of patients with atrial fibrillation on thromboprophylaxis in internal departments and cardiology of the Provin-cial Specialist Hospital in Włocławek. Materials and methods. The study group consisted of 100 people (63 men and 37 women) with diagnosed atrial fibrillation, taking oral anticoagulants. The research tool was the author's questionnaire. To assess the risk of ischem-ic stroke in this group of patients, the CHA2DS2-VASc scale was used and ques-tions about these factors were included in the survey. Results. Studies show that anticoagulant prophylaxis in the form of oral anti-coagulants is used in every patient with diagnosed atrial fibrillation. Most pa-tients use new generation drugs (NOAC) that do not require dose adjustment based on a normalized INR. Persistent atrial fibrillation was found in 51% of the patients. The most numerous group were patients in the 65-74 age range. The annual risk of stroke in my subjects was on average 11%. In most cases, patients correctly answered questions about the rules of conduct when using oral anticoagulants, factors that increase and weaken the effects of these drugs and the symptoms of their overdose. There were no significant differences in the level of knowledge between the women and men studied, while younger, better educated patients who declared a very good or satisfactory material situ-ation showed more knowledge. Conclusions. The study showed that the level of patients' knowledge about antithrombotic prophylaxis in atrial fibrillation is at a good level and corresponds to current medical knowledge.

Prior Stroke

The rising incidence of atrial fibrillation (AF) is increasingly resulting in a substantial worldwide increase in AF-related stroke, particularly in elderly patients and this is creating an increasingly serious healthcare burden. Guidelines recommend the use of AF-related stroke prophylaxis but adherence to these remains poor. Studies conducted in the 1990s showed that warfarin reduced the risk of AF-related stroke by an overall 64% compared with placebo. Subsequently, prophylactic treatment was further improved with the development of non-vitamin K antagonist oral anticoagulants (NOACs). More recently, a meta-analysis of four large clinical trials on NOACs (dabigatran, rivaroxaban, apixaban, and edoxaban) showed there was a relative risk reduction of 0.81 (p<0.0001) favouring NOAC treatment over warfarin for stroke or systemic embolic events in patients with AF. The largest trial of NOACs in AF-related stroke, to date, was the ENGAGE AF-TIMI 48 study (n=21,105) which showed that edoxaban was non-inferior to warfarin for ischaemic stroke reduction but significantly reduced bleeding and cardiovascular mortality. A recent subgroup analysis of this study showed that with edoxaban the incidences of intracranial haemorrhage (ICH) subtypes (all ICH, fatal ICH, fatal, subdural and epidural bleed) were significantly lower with 60 mg of edoxaban (p=0.013–<0.001). Edoxaban was also shown to be an effective option in patients with prior stroke. In addition, edoxaban was shown to reduce deaths due to fatal bleeds compared with warfarin. The results of current studies, especially the ENGAGE AF-TIMI 48 subgroup analysis therefore, show that the benefits of anticoagulation therapy in patients with AF substantially outweigh the risks.
