Analysis of Pharmacy Cardiac Optimization Clinic for Patients with New Onset Atrial Fibrillation Detected via Cardiac Implantable Electronic Device Clinic. PHARMACY 2023; 11:pharmacy11020048. [PMID: 36961026 PMCID: PMC10037589 DOI: 10.3390/pharmacy11020048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 02/21/2023] [Accepted: 02/25/2023] [Indexed: 03/08/2023] Open
Abstract
For patients with cardiac implantable electronic devices (CIEDs), arrythmias such as atrial fibrillation (AF) can be detected and actions taken to rapidly assess and initiate treatment where appropriate. Actions include timely initiation of anticoagulation, review of blood pressure, and optimization of cholesterol/lipids to prevent unfavorable outcomes, such as stroke and other cardiovascular complications. Delays to initiating anticoagulation can have devastating consequences. We sought to implement a virtual clinic, where a pharmacist reviews patient referrals from a CIED clinic after detecting AF from the CIED. Anticoagulation choice is determined by patient-specific factors, and a shared patient-provider decision to start oral anticoagulation is made. In addition, blood pressure readings and medications are assessed with lipid-lowering therapies for optimization. A total of 315 patients have been admitted through this clinic and anticoagulated over a two-year span; in addition, 322 successful interventions were made for optimization of cardiac therapy. Rapid initiation of anticoagulation within five days of referral was likely to have reduced unfavorable outcomes, such as stroke and other cardiovascular optimizations, leading to improved patient outcomes.

Abstract
The relationship between oral anticoagulants (OACs) and prognosis in elderly patients with atrial fibrillation (AF) has not been adequately explored. In this retrospective cohort study, we identified subjects aged over 80 from a database of 1140 AF patients discharged from the cardiology ward of a single tertiary center between 2015 and 2018. We examined the OAC treatment of octogenarian patients at discharge [VKA (vitamin K antagonist), NOAC (non-vitamin K antagonist oral anticoagulant), no OAC treatment]. We analyzed follow-up data of patients on OAC at discharge. The primary endpoint was all-cause death. The secondary endpoint was the incidence of stroke and major bleeding. The association of NOAC versus VKA treatment with these endpoints was assessed with multivariable Cox regression, using the VKA group as reference. A total of 330 octogenarian patients with AF were included with a mean (± SD) age of 83.9 ± 3.5 years. At discharge, 53.3% received a NOAC, 30% a VKA, and 16.7% no OAC. Patients on OAC were followed-up over a median of 2.6-years . The adjusted risk of all-cause death was not different in the NOAC group, compared with the VKA group (hazard ratio [HR], 0.72; 95% confidence intervals [CI] 0.50-1.03; P = 0.07). The risk of stroke or major bleeding was not different either (all P > 0.05). In conclusion, in this cohort of post-discharge octogenarian patients with AF, the risk for all-cause death was similar in NOAC versus VKA users, after adjustment for baseline covariates. No differences in stroke and major bleeding events among these treatment groups were revealed.

Abstract
OBJECTIVE To analyze the temporal trends of atrial fibrillation (AF)-related ischemic stroke (IS) and their relationship with the prescription patterns of antithrombotic treatment from 2013 to 2019 in the Health Assistance Area of a regional hospital. METHODS First, a retrospective ecological study of aggregate data to analyze the annual incidence of IS between 2013 and 2019 was performed. Second, we selected those patients diagnosed with AF between 2013 and 2019 and performed a retrospective longitudinal study to assess the role of antithrombotic therapy in the development of AF-related IS. RESULTS During this period, whereas the annual incidence of IS remained stable (from 1.3 in 2013 to 1.2 cases per 1000 inhabitants in 2019; adjusted P for trend .829), the annual incidence of AF-related IS decreased over time (from 23.8 to 18.8 cases per 1000 inhabitants, respectively; adjusted P for trend .001). Among AF patients, the use of direct oral anticoagulants increased from 5.5% to 46.8%, while the prescription of antiplatelets and vitamin K antagonists decreased from 21.9% to 6.0% and from 63.8% to 36.1%, respectively. Overall, the use of oral anticoagulants increased from 69.3% to 82.9%; p < .001. Patients under antiplatelet agents had a higher probability of presenting IS than those patients taking oral anticoagulants, either vitamin K antagonists or direct oral anticoagulants (adjusted OR 1.89; 95% CI 1.52-2.37; p < .001). CONCLUSIONS The prescription of oral anticoagulants, particularly direct oral anticoagulants, has increased from 2013 to 2019 in our Health Assistance Area. This increase might partially explain the reduction in AF-related IS.

Abstract
Background Atrial fibrillation (AF) increases the risk of stroke and extracranial systemic embolic events (SEEs), but little is known about the magnitude of the association of AF with SEE. Methods and Results This analysis included 14 941 participants of the ARIC (Atherosclerosis Risk in Communities) study (mean age, 54.2±5.8, 55% women, 74% White) without AF at baseline (1987–1989) followed through 2017. AF was identified from study ECGs, hospital discharges, and death certificates, while SEEs were ascertained from hospital discharges. CHA2DS2‐VASc was calculated at the time of AF diagnosis. Cox regression was used to estimate associations of incident AF with SEE risk in the entire cohort, and between CHA2DS2‐VASc score and SEE risk in those with AF. Among eligible participants, 3114 participants developed AF and 270 had an SEE (59 events in AF). Incident AF was associated with increased risk of SEE (hazard ratio [HR], 3.58; 95% CI, 2.57–5.00), after adjusting for covariates. The association of incident AF with SEE was stronger in women (HR, 5.26; 95% CI, 3.28–8.44) than in men (HR, 2.68; 95% CI, 1.66–4.32). In those with AF, higher CHA2DS2‐VASc score was associated with increased SEE risk (HR per 1‐point increase, 1.24; 95% CI, 1.05–1.47). Conclusions AF is associated with more than a tripling of the risk of SEE, with a stronger association in women than in men. CHA2DS2‐VASc is associated with SEE risk in AF patients, highlighting the value of the score to predict adverse outcomes and guide treatment decisions in people with AF.

Abstract
OBJECTIVE Ensuring patients with Atrial fibrillation (AF) are appropriately anticoagulated across NHS Bedfordshire Clinical Commissioning Group (BCCG) with the primary goal of reducing AF-related strokes. METHODS With Inspira Health, BCCG adopted the Primary Care Atrial Fibrillation (PCAF) Service which is led by Consultant Cardiologists. PCAF uses retrospective clinical audit to identify patients who require prospective face-to-face review on the need for anticoagulation. RESULTS 34 GP practices participated covering a 376 311 population (80% of BCCG). 12 573 patients' medical records were audited. The initial AF register was 7301 patients (AF prevalence 1.9%) and an additional 265 patients were identified through AF casefinder resulting in an AF prevalence of 2.0%. From 7566 patients with AF, 5831 were already on anticoagulants (77.1%), with 50.5% (n = 2947) on VKA medications and 49.5% (n = 2884) on direct oral anticoagulants (DOACs). Of the DOAC patients, 595 (20.6%) required dosage review or up to date blood tests. Case notes were reviewed for 1735 patients not on anticoagulation, with 901 (51.9%) patients deemed not eligible for anticoagulation. This left 834 (48.1%) patients who were eligible for, but not on, anticoagulation. A further 407 (13.8%) patients currently taking VKA medications were deemed sup-optimal with regards to INR control with TTR < 65%. In total 1241 patients were invited for review by a Consultant Cardiologist at their local GP practice, with an attendance rate of 90%. From all face to face and virtual consultations, 908 patients had anticoagulants prescribed, changed, management of INRs improved or were in the process of being anticoagulated at the time of follow-up. From this we would expect 36.3 AF related strokes prevented and a cost saving to the NHS of £470 200 per year. CONCLUSION Through comprehensive audit, BCCG have been able to ensure that patients with AF are appropriately anticoagulated in 80% of their catchment population. This has improved anticoagulation to prevent AF-related stroke.

Abstract
BACKGROUND Guideline-adherent antithrombotic treatment (ATT) reduces the risk of stroke and death in patients with atrial fibrillation (AF). However, the effect of ATT adherence among different ethnicities remains uncertain. We compared the prognosis of AF patients in Japan and the UK according to guideline adherence status.Methods and Results:We compared the clinical characteristics and outcomes of AF patients from the Fushimi AF registry (Japan; n=4,239) and the Darlington AF registry (UK; n=2,259). ATT adherence was assessed against the Japanese Circulation Society Guidelines and UK National Institute for Health and Care Excellence guidelines. The rates of guideline-adherent ATT were 58.6% and 50.8% in the Fushimi and Darlington registries, respectively. There was no significant difference in 1-year stroke rates between Fushimi and Darlington (2.6% vs. 3.0%, P=0.342). On multivariate logistic regression analysis, non-guideline adherent-ATT was significantly associated with an increased risk of stroke (odds ratio [OR]: 1.69, 95% confidence interval [CI]: 1.21-2.34, P=0.002 for undertreatment, OR: 2.13, 95% CI: 1.19-3.80, P=0.010 for overtreatment). No significant interaction for ATT and the 2 populations was found in the incidence of stroke, all-cause death, and the composite outcome. CONCLUSIONS Approximately half of the AF patients received optimal ATT according to guideline recommendations, which was associated with a lower risk of stroke. Furthermore, there was no interaction for the 2 populations and the influence of ATT adherence.

One-year risks of stroke and mortality in patients with atrial fibrillation from different clinical settings: The Gulf SAFE registry and Darlington AF registry. Int J Cardiol 2018; 274:158-162.

Abstract
BACKGROUND Differences exist in oral anticoagulation (OAC) use between different populations with atrial fibrillation (AF), which may be associated with varying outcomes. PURPOSE We aimed to provide patient level comparisons of two cohorts of patients with AF, from the United Kingdom (UK) and Middle East (ME). METHODS The clinical characteristics, prescription of OAC, one-year risk of stroke and mortality were compared between individual patients with AF included into the Darlington AF registry (UK, n = 2258) and the Gulf SAFE (Survey of atrial fibrillation events) registry (ME, n = 1740). RESULTS A high percentage of patients from the Darlington registry were candidates for OAC (i.e., CHA2DS2-VASc score ≥2 in males or ≥3 in females; 82.0% in Darlington and 57.1% in Gulf SAFE). OAC use was suboptimal (52.0% in Darlington vs 58.4% in Gulf SAFE). One-year rates of stroke and mortality were high in both populations, especially in those with CHA2DS2-VASc score ≥2 in males and ≥3 in females (Darlington vs. Gulf SAFE: 3.51% vs. 5.63 for stroke; 11.4% vs. 16.8% for mortality). On multivariate analyses, female sex and previous stroke were independently associated with stroke events; while elderly age, female sex, vascular disease and heart failure were independent risk factors for mortality (all p < 0.05). Patients from Gulf SAFE registry had higher risk of stroke (odds ratio, 2.18 [1.47-3.23]) and mortality (odds ratio, 1.67 [1.31-2.14]) compared with those from Darlington registry. The CHA2DS2-VASc score showed good discrimination in predicting one-year risk of stroke (area under curve, 0.71 [0.65-0.76] in non-anticoagulated patients) and mortality (area under curve, 0.70 [0.68-0.72]) in the whole study population, as well as in Darlington or Gulf SAFE registry separately. CONCLUSIONS Stroke prevention was generally suboptimal in patient cohorts from the two registries, which was associated with high one-year risks of stroke and mortality, particularly so among patients from the Gulf SAFE registry. The higher risks for stroke and mortality in AF patients from the Gulf SAFE registry (compared to a UK cohort) merit further implementation of cardiovascular prevention strategies.

Abstract
Background Familiarity and competency in the options for stroke prevention in atrial fibrillation (AF) and the role of non-vitamin K antagonist oral anticoagulants (NOACs) may vary among primary care physicians (PCPs) from different European countries. Aims To investigate PCP views on prescribing and managing NOACs across Europe and identify perceived unmet needs. Design & setting Web-based survey including PCPs with particular interest in cardiovascular medicine. Method A questionnaire was drawn up, containing 10 questions on initiation and ongoing management of NOACs; use of AF stroke guidelines on NOACs and anticoagulant switching; and perceived information needs. Results The overall response rate was 42%. The majority of PCPs declared they are responsible for and confident in both initiating and managing NOAC therapy. In some countries, PCPs are not able to initiate NOAC therapy due to administrative barriers (namely, Italy and Slovakia). No single set of guidelines is referred to across all countries and over a fifth of responders indicate they do not follow specific guidelines. The main learning needs reported were more related to initiation than to ongoing management of anticoagulant therapy. Conclusion According to this self-assessment survey, the experience of most PCPs in management of different aspects of AF appears good and only some felt the need for further training. However, in the light of the importance of this topic as public health issue, intensified efforts aiming at better equipping PCPs to meet their key roles in an integrated service across Europe are overdue.

Guideline-Adherent Antithrombotic Treatment Improves Outcomes in Patients With Atrial Fibrillation: Insights From the Community-Based Darlington Atrial Fibrillation Registry. Mayo Clin Proc 2017; 92:1203-1213. [PMID: 28778255 DOI: 10.1016/j.mayocp.2017.05.023] [Citation(s) in RCA: 30] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2016] [Revised: 04/10/2017] [Accepted: 05/04/2017] [Indexed: 12/17/2022]
Abstract
OBJECTIVE To assess the influence of guideline-adherent vs nonadherent antithrombotic treatment (ATT) on stroke and mortality rates in an atrial fibrillation (AF) primary care population. PATIENTS AND METHODS We used the Darlington Registry cohort, which included 105,000 patients from March 31, 2012, through March 31, 2013. Guideline adherence in ATT was assessed against 2014 National Institute for Health and Care Excellence guidelines, which recommend oral anticoagulation for stroke prevention as a default management unless a truly low risk of stroke (CHA2DS2-VASc=0 in men and 1 in women) is evident. RESULTS Of 2259 patients with AF (2.15%), 36.1% were undertreated, 50.8% were guideline adherent, and 13.1% were overtreated. Oral anticoagulation was declined by 5.0% and contraindicated in 8.3%. Of 67 incident strokes (3.0%), 66 (98.5%) occurred in high-risk patients (CHA2DS2-VASc ≥2). For the high-risk cohort, 1-year stroke rates were 4.5% (95% CI, 3.2%-6.3%) for undertreatment, 1.9% (95% CI, 1.2%-2.9%) for guideline adherence, and 7.2% (95% CI, 4.4%-11.6%) for overtreatment; corresponding mortality rates were 16.1% (95% CI, 13.6%-19.0%), 8.0% (95% CI, 6.5%-9.8%), and 8.2% (95% CI, 5.2%-12.7%), respectively. On multivariable analysis, both undertreatment and overtreatment of high-risk patients were associated with significant increases in stroke rates (odds ratio [OR]=2.32; 95% CI, 1.30-3.14; P=.005 and OR=2.28; 95% CI, 1.12-4.63; P=.02, respectively). Undertreatment was also associated with a significant increase in all-cause mortality (OR=1.59; 95% CI, 1.14-2.21; P=.006). CONCLUSION Only half of all eligible patients with AF are prescribed oral anticoagulation in accordance with guideline recommendations. Guideline-adherent ATT significantly reduces the risk of stroke and improves survival.

Underuse of Oral Anticoagulants and Inappropriate Prescription of Antiplatelet Therapy in Older Inpatients with Atrial Fibrillation. Drugs Aging 2017; 34:701-710.

Abstract
BACKGROUND Several studies have shown that the prescription of antiplatelet therapy (APT) is associated with an increased risk of oral anticoagulant (OAC) underuse in patients aged 75 years and over with atrial fibrillation (AF). An associated atheromatous disease may be the underlying reason for APT prescription. The objective of the study was to determine whether the association between underuse of OAC and APT prescription was explained by the presence of an atheromatous disease. METHODS AND RESULTS We performed a retrospective, observational, single-centre study between 2009 and 2013 based on administrative data. Patients aged 75 years and over with non-valvular AF were identified in a database of 72,090 hospital stays. Prescriptions of anti-thrombotic medications and their association with the presence of atheromatous disease were evaluated by the mean of a logistic regression. A total of 2034 hospital stays were included (mean age 84.3 ± 5.2 years). The overall prevalence of known atheromatous disease was 25.9%. OAC underuse was observed in 58.5% of the stays. In multivariable analysis, the prescription of an APT was associated with an increased risk of OAC underuse [odds ratio (OR) 6.85; 95% confidence interval (CI) 5.50-8.58], independently of the presence of a concomitant known atheromatous disease (OR 0.78; 95% CI 0.60-1.01). Among the 692 stays with APT monotherapy (34.0%), 232 (33.5%) displayed an atheromatous disease. CONCLUSIONS The underuse of OAC is associated with the prescription of APT in older patients with AF, regardless of the presence or absence of known atheromatous disease. Our results suggest that APT is often inappropriately prescribed instead of OAC.

Abstract
BACKGROUND AND PURPOSE Although patients with atrial fibrillation (AF) who experienced an acute stroke are at high risk for recurrence, many patients are untreated or treated suboptimally for stroke prevention. The objective of this study is to compare clinical outcomes of AF patients with versus without previous stroke in relation to guideline-adherent antithrombotic treatment in a contemporary primary care population. METHODS Community cohort of 105 000 patients from 11 general practices in Darlington, England, was used to assess AF stroke prevention strategies against 2014 National Institute for Health and Care Excellence guidelines. RESULTS Overall, 2259 (2.15%) patients with AF were identified, of which 18.9% constituted a secondary prevention cohort. For secondary prevention, antithrombotic treatment was guideline adherent in 56.3%, 18.9% were overtreated, and 24.8% undertreated; corresponding proportions for primary prevention were 49.5%, 11.7%, and 38.8%, respectively. One-year stroke rates were 8.6% and 1.6% for secondary and primary prevention, respectively (P<0.001); corresponding all-cause mortality rates were 9.8% and 9.4%, respectively (P=0.79). On multivariable analysis, lack of antithrombotic treatment guideline adherence was associated with increased stroke risk for primary prevention (odds ratio, 2.95; 95% confidence interval, 1.26-6.90; P=0.013 for undertreatment); for secondary prevention, lack of guideline adherence was associated with increased risk of recurrent stroke (odds ratio, 2.80; 95% confidence interval, 1.25-6.27; P=0.012 for overtreatment) and all-cause death (odds ratio, 2.75; 95% confidence interval, 1.33-5.69; P=0.006 for undertreatment). CONCLUSIONS Only approximately half of eligible patients with AF are prescribed oral anticoagulation in line with guidelines. Guideline-adherent antithrombotic treatment significantly reduces the risk of stroke among primary prevention patients and both risk of recurrent stroke and death in patients with previous stroke.

Abstract
In Europe, 1-3% of the population suffers from atrial fibrillation (AF) and has increased stroke risk. By 2060 a doubling in number of cases and great burden in managing this medical condition are expected. This paper offers an overview of data on epidemiology and management of AF and stroke in four European countries as well as the interconnection between these dimensions. A search index was developed to access multiple scientific and "grey" literatures. Information was prioritised based on strength of evidence and date. Information on country reports was double-checked with national experts. The overall prevalence of AF is consistent across countries. France has the lowest stroke incidence and mortality, followed by Netherland and UK, while Romania has higher rates. GPs or medical specialists are responsible for AF treatment; exception are the special thrombosis services in the Netherlands. Prevention measurements are only present in UK through screening programs. Although international and national guidelines are available, undertreatment is present in all countries. Despite differences in healthcare systems and management of AF, epidemiology is comparable between three of the countries. Romania is an outlier, by being limited in data accessibility. This knowledge can contribute to improved AF care in Europe.

Abstract
Atrial fibrillation (AF) is a common arrhythmia managed by many physicians in a variety of clinical settings. One of the most important clinical decisions related to effective AF management centers upon the need to perform accurate thromboembolic risk stratification followed by effective management decisions that align with established guidelines. This manuscript will review the present state of the art and provide guidance to physicians to enhance patient outcomes.

Abstract
Supplemental Digital Content is available in the text. Background and Purpose— Long-term benefits of initiating stroke prophylaxis in the emergency department (ED) are unknown. We analyzed the long-term safety and benefits of ED prescription of anticoagulation in atrial fibrillation patients. Methods— Prospective, multicenter, observational cohort of consecutive atrial fibrillation patients was performed in 62 Spanish EDs. Clinical variables and thromboprophylaxis prescribed at discharge were collected at inclusion. Follow-up at 1 year post-discharge included data about thromboprophylaxis and its complications, major bleeding, and death; risk was assessed with univariate and bivariate logistic regression models. Results— We enrolled 1162 patients, 1024 (88.1%) at high risk according to CHA2DS2-VASc score. At ED discharge, 935 patients (80.5%) were receiving anticoagulant therapy, de novo in 237 patients (55.2% of 429 not previously treated). At 1 year, 48 (4.1%) patients presented major bleeding events, and 151 (12.9%) had died. Anticoagulation first prescribed in the ED was not related to major bleeding (hazard ratio, 0.976; 95% confidence interval, 0.294–3.236) and was associated with a decrease in mortality (hazard ratio, 0.398; 95% confidence interval, 0.231–0.686). Adjusting by the main clinical and sociodemographic characteristics, concomitant antiplatelet treatment, or destination (discharge or admission) did not affect the results. Conclusions— Prescription of anticoagulation in the ED does not increase bleeding risk in atrial fibrillation patients at high risk of stroke and contributes to decreased mortality.

Abstract
BACKGROUND Ethnic differences in clinical characteristics, stroke risk profiles and outcomes among atrial fibrillation (AF) patients may exist. We therefore compared AF patients with previous stroke from Japan and the United Kingdom (UK). METHODS We compared clinical characteristics, stroke risk and outcomes among AF patients from the Fushimi AF registry who had experienced a previous stroke (Japan; n=688; 19.7%) and the Darlington AF registry (UK; n=428; 19.0%). RESULTS AF patients with previous stroke in Fushimi were significantly younger (76.8 and 79.6years of age in Fushimi and Darlington; p<0.01) with a lower proportion of females (37.4% vs. 45.1%; p=0.01) than those from Darlington. Although the CHA2DS2-VASc score was lower in AF patients in Fushimi than those in Darlington (5.18 vs. 5.57; p<0.01), oral anticoagulation (OAC) was prescribed significantly more frequently in Fushimi (68.3%) than Darlington (61.7%) (p=0.02). Multivariate logistic regression analysis showed that Japanese ethnicity was associated with a significantly decreased risk of recurrent stroke (OR 0.59. 95% CI 0.36-0.97; p=0.04) but a significantly increased risk of all-cause mortality (OR 1.76, 95% CI 1.18-2.66; p<0.01) in AF patients with previous stroke. CONCLUSIONS AF patients with previous stroke in the UK were at higher risk of recurrent stroke compared to Japanese patients, but OAC was utilised less frequently. There was a lower risk of recurrent stroke in the secondary prevention cohort from the Fushimi registry, but an increased risk of all-cause mortality.

Abstract
The prevalence of atrial fibrillation (AF) in the general population is between 1% and 2% in the developed world and is higher in men than in women. The arrhythmia occurs much more commonly in the elderly, and the estimated lifetime risk of developing AF is one in four for men and women aged 40 years and above. Projected data from multiple population-based studies in the USA and Europe predict a two- to threefold increase in the number of AF patients by 2060. The high lifetime risk of AF and increased longevity underscore the important public health burden posed by this arrhythmia worldwide. AF has multiple aetiologies and a broad variety of presentations. The primary pathologies underlying or promoting the occurrence of AF vary more than for any other cardiac arrhythmia, ranging from autonomic imbalance to organic heart disease and metabolic disorders, such as diabetes mellitus, metabolic syndrome, hyperthyroidism and kidney disease, and lifestyle factors such as smoking, alcohol consumption and participation in endurance sports. Biomarkers are increasingly being investigated and, together with clinical and genetic factors, will eventually lead to a clinically valuable detailed classification of AF which will also incorporate pathophysiological determinants and mechanisms of the arrhythmia. In turn, this will allow the development and application of precision medicine to this troublesome arrhythmia.

Abstract
AbstractObjective:This study aimed to compare management, readmission rates and length of in-patient stay amongst warfarinised and non-warfarinised patients to ascertain future treatment protocols.Methods:A 12-month retrospective review was conducted of ENT epistaxis admissions. Admission details such as length of in-patient stay, clotting profile and management plan were recorded. Comparisons of management and outcome for warfarinised and non-warfarinised patients were made using the Fisher's exact paired t-test.Results:Of 176 epistaxis patients admitted, 31 per cent were warfarinised, 18 per cent were on another form of anticoagulation or antiplatelet therapy, and 51 per cent were not on any medication that might impose a bleeding risk. The international normalised ratio at admission was high in 13 per cent of warfarinised patients; the remaining patients had therapeutic or sub-therapeutic international normalised ratios and so warfarin was continued. The mean in-patient stay was similar for all cohorts; however, warfarinised patients had a higher readmission rate.Conclusion:Warfarinised epistaxis patients may be safely managed without stopping their anticoagulation therapy, provided their international normalised ratio is at therapeutic or sub-therapeutic levels. By continuing regular anticoagulation therapy, warfarinised patients may be discharged without delay.

Abstract
OBJECTIVE Stroke-risk in atrial fibrillation (AF) can be significantly reduced by appropriate thromboembolic prophylaxis. However, National Institute for Health and Care Excellence estimates suggest that up to half of eligible patients with AF are not anticoagulated, with severe consequences for stroke prevention. We aimed to determine the outcome of an innovative Primary Care AF (PCAF) service on anticoagulation uptake in a cohort of high-risk patients with AF in the UK. METHODS The PCAF service is a novel cooperative pathway providing specialist resources within general practitioner (GP) practices. It utilises a four-phase protocol to identify high-risk patients with AF (CHA2DS2-VASc ≥ 1) who are suboptimally anticoagulated, and delivers Consultant-led anticoagulation assessment within the local GP practice. We assessed rates of anticoagulation in high-risk patients before and after PCAF service intervention, and determined compliance with newly-initiated anticoagulation at follow-up. RESULTS The PCAF service was delivered in 56 GP practices (population 386,624; AF prevalence 2.1%) between June 2012 and June 2014. 1579 high-risk patients with AF with suboptimal anticoagulation (either not taking any anticoagulation or taking warfarin but with a low time-in-therapeutic-range) were invited for review, with 86% attending. Of 1063 eligible patients on no anticoagulation, 1020 (96%) agreed to start warfarin (459 (43%)) or a non-vitamin K antagonist oral anticoagulant (NOAC, 561 (53%)). The overall proportion of eligible patients receiving anticoagulation improved from 77% to 95% (p<0.0001). Additionally, 111/121 (92%) patients suboptimally treated with warfarin agreed to switch to a NOAC. Audit of eight practices after 195 (185-606) days showed that 90% of patients started on a new anticoagulant therapy had continued treatment. Based on data extrapolated from previous studies, around 30-35 strokes per year may have been prevented in these previously under-treated high-risk patients. CONCLUSIONS Systematic identification of patients with AF with high stroke-risk and consultation in PCAF consultant-led clinics effectively delivers oral anticoagulation to high-risk patients with AF in the community.

Abstract
Heart failure (HF) is associated with an increased risk of thrombotic events, particularly if this condition is accompanied by atrial fibrillation (AF). Many HF patients have background coronary artery disease (CAD) making them prone to coronary thrombosis resulting in myocardial infarction or sudden death. Oral anticoagulation is essential in the vast majority of HF patients with AF with non-vitamin K based anticoagulants being a suitable alternative to warfarin. In contrast, aspirin alone does not provide adequate stroke prevention in such patients. In HF without AF, oral anticoagulation should not be routinely used, and antiplatelet agents should be prescribed in patients with background CAD. This review provides an overview of prothrombotic factors and antithrombotic management of patients with HF.
