Time-in-therapeutic-range defined warfarin and direct oral anticoagulants in atrial fibrillation: a Nationwide Cohort Study. Ann Med 2024; 56:2364825. [PMID: 38873855 PMCID: PMC11182072 DOI: 10.1080/07853890.2024.2364825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2024] [Accepted: 04/30/2024] [Indexed: 06/15/2024] Open
Abstract
BACKGROUND Little is known how individual time-in-therapeutic-range (TTR) impacts the effectiveness and safety of warfarin therapy compared to direct oral anticoagulants (DOACs) in patients with atrial fibrillation (AF). OBJECTIVE To compare the effectiveness and safety of standard dose DOACs to warfarin in patients with AF, while categorizing warfarin treated patients into quartiles based on their individual TTR. MATERIALS AND METHODS We conducted a nationwide study including all patients with new-onset AF between 2011 and 2018 in Finland. Hazard ratios (HR) were calculated using Cox regression analysis with the inverse probability of treatment weighted method to assess the risks of ischaemic stroke (IS), intracranial haemorrhage (ICH) and mortality for users of apixaban (n = 12,426), dabigatran (n = 4545), rivaroxaban (n = 12,950) and warfarin (n = 43,548). RESULTS The median TTR for warfarin users was 72%. Compared to the second best TTR quartile (reference), the risk of IS was higher in the two poorest TTR quartiles, and lower in the best TTR quartile and on rivaroxaban [2.35 (95% confidence interval, 1.85-2.85), 1.44 (1.18-1.75), 0.60 (0.47-0.77) and 0.72 (0.56-0.92)]. These differences were non-significant for apixaban and dabigatran. HR of ICH was 6.38 (4.88-8.35) and 1.87 (1.41-2.49) in the two poorest TTR groups, 1.44 (1.02-1.93) on rivaroxaban, and 0.58 (0.40-0.85) in the best TTR group compared to the reference group. Mortality was higher in the two poorest TTR groups and lowest in the best TTR group. CONCLUSIONS The outcome was unsatisfactory in the two lowest TTR quartiles - in half of the patients treated with warfarin. The differences between the high TTR groups and standard dose DOACs were absent or modest.

[PMID: 38880419 DOI: 10.1016/j.ijcard.2024.132276] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2024] [Revised: 06/12/2024] [Accepted: 06/13/2024] [Indexed: 06/18/2024]
Abstract
BACKGROUND Frailty and comorbidity influence the therapeutic approach in everyday clinical practice. The DOACs genericization opens a reflection on their differences from a pharmacological and bioavailability point of view, particularly in elderly frail patients. The aim of this project was to create a national Delphi consensus on the topic of the use of DOACs for atrial fibrillation (AF) in such patients, in light of the genericization of the class. METHODS AND RESULTS The consensus dealt with 3 main topics: a) efficacy and safety of DOACs in elderly and/or frail patients; b) therapeutic choice in specific frailty scenarios; c) DOACs genericization. 56 cardiologists, two internists and two neurologists from Italy expressed their level of agreement on each statement by using a 5-point Likert scale (1: strongly disagree, 2: disagree, 3: uncertain, 4: agree, 5: strongly agree). A positive consensus was reached if the percentage of agreement (vote 1-2, positive consensus) or disagreement (votes 4-5, negative consensus) was >66%; otherwise, no consensus was reached. Results are displayed accordingly. CONCLUSIONS After 10 years of everyday clinical management of DOACs for AF, specific elements differentiating a molecule from another, either for efficacy or for safety, are consolidated. However, some uncertainties still exist in particular contexts, such as chronic kidney disease or cancer patients. Clinicians have an unsure attitude towards generic drugs, because clinical practice is lacking as well as a proper knowledge of the topic. Albeit being an alternative, the choice of the generic drug must remain the responsibility of the clinician.

Abstract
In the last three decades, ablation of atrial fibrillation (AF) has become an evidence-based safe and efficacious treatment for managing the most common cardiac arrhythmia. In 2007, the first joint expert consensus document was issued, guiding healthcare professionals involved in catheter or surgical AF ablation. Mounting research evidence and technological advances have resulted in a rapidly changing landscape in the field of catheter and surgical AF ablation, thus stressing the need for regularly updated versions of this partnership which were issued in 2012 and 2017. Seven years after the last consensus, an updated document was considered necessary to define a contemporary framework for selection and management of patients considered for or undergoing catheter or surgical AF ablation. This consensus is a joint effort from collaborating cardiac electrophysiology societies, namely the European Heart Rhythm Association, the Heart Rhythm Society, the Asia Pacific Heart Rhythm Society, and the Latin American Heart Rhythm Society.

Abstract
Atrial fibrillation (AF) is globally the most common arrhythmia associated with significant morbidity and mortality. It impairs the quality of the patient's life, imposing a remarkable burden on public health, and the healthcare budget. The detection of AF is important in the decision to initiate anticoagulation therapy to prevent thromboembolic events. Nonetheless, AF detection is still a major clinical challenge as AF is often paroxysmal and asymptomatic. AF screening recommendations include opportunistic or systematic screening in patients ≥65 years of age or in those individuals with other characteristics pointing to an increased risk of stroke. The popularities of well-being and taking personal responsibility for one's own health are reflected in the continuous development and growth of mobile health technologies. These novel mobile health technologies could provide a cost-effective solution for AF screening and an additional opportunity to detect AF, particularly its paroxysmal and asymptomatic forms.

APPLIED HEALTH ECONOMICS AND HEALTH POLICY 2024; 22:725-734. [PMID: 38858344 DOI: 10.1007/s40258-024-00891-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 05/14/2024] [Indexed: 06/12/2024]
Abstract
BACKGROUND This study aimed to assess the cost-effectiveness of non-vitamin K antagonist oral anticoagulants (NOACs) in comparison with warfarin using data from real practice based on the perspective of the health care system in Thailand. METHODS A four-state Markov model encompassing well-controlled atrial fibrillation (AF), stroke and systemic embolism, major bleeding and death was utilised to forecast clinical and economic outcomes. Transitional probabilities, direct medical costs and utilities were derived from the real-world data of the 'COOL-AF Thailand' registry, Thailand's largest nationwide registry spanning 27 hospitals. The cohort comprised AF patients. The primary outcomes assessed were total costs, life years, quality-adjusted life years (QALYs) and the incremental cost-effectiveness ratio. All costs and outcomes were subject to an annual discount rate of 3.0%. A spectrum of sensitivity analyses was conducted. RESULTS The mean age of the cohort was 68.8 ± 10.7 years. The NOACs group incurred a marginally lower total lifetime cost than the warfarin group (247,857 Thai baht [THB] vs 253,654 THB or 7137 USD vs 7304 USD) and experienced gains of 0.045 life years and 0.043 QALYs over the warfarin group. Given the lower cost and higher benefits associated with NOACs, this implies that NOAC treatment is a dominant strategy compared to warfarin for AF patients. At a ceiling ratio of 160,000 THB (4607 USD) per QALY, NOACs presented a 61.2% probability of being cost effective. CONCLUSIONS Non-vitamin K antagonist oral anticoagulants represent a cost-saving alternative to warfarin in the real clinical practice. However, with a probability of being cost effective below 65%, it suggests some parameter uncertainty regarding their overall cost effectiveness compared to warfarin.

Abstract
BACKGROUND Inhibiting the coagulation factor XI (FXI) is a novel strategy for prevention and treatment of thromboembolism without affecting extrinsic coagulation pathways. SHR-2004 is a humanized monoclonal antibody that selectively binds to FXI and factor XIa (FXIa). RESEARCH DESIGN & METHODS This randomized, double-blind, dose-escalation, placebo-controlled study evaluated SHR-2004 administered either intravenously (i.v.; Part A) or subcutaneously (s.c.; Part B). In Part A, 24 subjects received a single i.v. dose of SHR-2004 (0.1, 0.3, or 1.0 mg/kg) or placebo. In Part B, 40 subjects received a single s.c. dose of SHR-2004 (0.5, 1.0, 3.0, or 4.5 mg/kg) or placebo. RESULTS SHR-2004 was well tolerated. Plasma exposure to SHR-2004 increased in a dose-dependent manner. The geometric mean half-time ranged from 11.6 to 13.0 days. FXI activity decreased, and the activated partial thromboplastin time (APTT) was prolonged after i.v. and s.c. administration in a dose- and time-dependent manner. FXI activity was nearly completely abolished immediately after administering the highest i.v. dose, with the average APTT prolonged to nearly three times of baseline. CONCLUSION SHR-2004 is a promising candidate for further development as an anticoagulant drug that exerts effective anticoagulation with minimal risk of bleeding. CLINICAL TRIAL REGISTRATION www.clinicaltrials.gov identifier is NCT05369767.

Abstract
Atrial fibrillation (AF) is associated with an increased risk of stroke and systemic embolism, and the left atrial appendage (LAA) has been identified as a principal source of thromboembolism in these patients. While oral anticoagulation is the current standard of care, LAA closure (LAAC) emerges as an alternative or complementary treatment approach to reduce the risk of stroke or systemic embolism in patients with AF. Moderate-sized randomized clinical studies have provided data for the efficacy and safety of catheter-based LAAC, largely compared with vitamin K antagonists. LAA device iterations, advances in pre- and peri-procedural imaging, and implantation techniques continue to increase the efficacy and safety of LAAC. More data about efficacy and safety of LAAC have been collected, and several randomized clinical trials are currently underway to compare LAAC with best medical care (including non-vitamin K antagonist oral anticoagulants) in different clinical settings. Surgical LAAC in patients with AF undergoing cardiac surgery reduced the risk of stroke on background of anticoagulation therapy in the LAAOS III study. In this review, we describe the rapidly evolving field of LAAC and discuss recent clinical data, ongoing studies, open questions, and current limitations of LAAC.

Left Atrial Appendage Closure Compared With Oral Anticoagulants for Patients With Atrial Fibrillation: A Systematic Review and Network Meta-Analysis. J Am Heart Assoc 2024; 13:e034815.

Abstract
BACKGROUND Percutaneous left atrial appendage closure (LAAC) has been suggested as an alternative to long-term oral anticoagulation for nonvalvular atrial fibrillation, but comparative data remain scarce. We aimed to assess ischemic and bleeding outcomes of LAAC compared with vitamin K antagonists (VKAs) or direct oral anticoagulants (DOACs) for the prevention of cardioembolic events in patients with atrial fibrillation. METHODS AND RESULTS Embase and MEDLINE were searched for randomized trials comparing LAAC, VKAs, and DOACs. The primary efficacy end point was any stroke or systemic embolism. Treatment effects were calculated from a network meta-analysis and ranked according to the surface under the cumulative ranking curve. Seven trials and 73 199 patients were included. The risk of the primary end point was not statistically different between LAAC versus VKAs (odds ratio [OR], 0.92 [95% CI, 0.62-1.50]) and LAAC versus DOACs (OR, 1.11 [95% CI, 0.71-1.73]). LAAC and DOACs resulted in similar risk of major or minor (OR, 0.93 [95% CI, 0.61-1.42]) and major bleeding (OR, 0.92 [95% CI, 0.58-1.46]); however, after exclusion of procedural bleeding, bleeding risk was significantly lower in those undergoing LAAC. Both LAAC and DOACs reduced the risk of all-cause death compared with VKAs (LAAC versus VKAs: OR, 0.70 [95% CI, 0.53-0.91]; DOACs versus VKAs: OR, 0.90 [95% CI, 0.85-0.95], respectively). DOACs ranked as the best treatment for stroke or systemic embolism prevention (66.9%) and LAAC for reducing major bleeding (63.9%) and death (96.4%). CONCLUSIONS As a nonpharmacological alternative to oral anticoagulation for atrial fibrillation, LAAC showed similar efficacy and safety compared with VKAs or DOACs. Prospective confirmation from larger studies is warranted.

Clin Res Cardiol 2024:10.1007/s00392-024-02517-z.

Abstract
BACKGROUND Transcatheter edge-to-edge repair for severe tricuspid regurgitation (TR) is a new treatment option (t-TEER). Data on optimal antithrombotic therapy after t-TEER in patients with an indication for anticoagulation are scarce and evidence-based guideline recommendations are lacking. We sought to investigate efficacy and safety of novel oral anticoagulation (NOAC) and vitamin-K-antagonists (VKA) in patients undergoing t-TEER. METHODS Among 78 consecutive patients with t-TEER of severe TR, 69 patients were identified with concomitant indication for oral anticoagulation. Outcomes of these patients treated with NOAC or VKA were compared over a median follow-up period of 327 (177-460) days. RESULTS Despite elevated thromboembolic and bleeding risk scores (CHA2DS2-VASc 4.2 ± 1.1, HEMORR2HAGES 3.0 ± 1.0 and HAS-BLED 2.1 ± 0.8), only one major bleeding incidence occurred under NOAC therapy. The risk for overall (NOAC 8% vs. VKA group 26%, p = 0.044) and major bleeding events (NOAC 2% vs. VKA 21%, p = 0.010) was significantly lower in the NOAC compared to the VKA group. No significant difference was found between NOAC and VKA treatment in terms of mortality (NOAC 18% vs. VKA 16%, p = 0.865) or the combined endpoint of death, heart failure hospitalization, stroke, embolism, thrombosis, myocardial infarction, and severe bleeding (NOAC 48% vs. VKA 42%, p = 0.801). A comparison between apixaban (n = 27) and rivaroxaban (n = 16) treated patients revealed no significant differences between NOAC substances (all bleeding events apixaban 7% vs. rivaroxaban 13%, p = 0.638). CONCLUSION Results of this study indicate that NOACs may offer a favorable risk-benefit profile for patients with concomitant indication for anticoagulation therapy following t-TEER.

Abstract
Atrial fibrillation (AF), the most common sustained cardiac arrhythmia, is not a dichotomous disease trait. Technological innovations enable long-term rhythm monitoring in many patients and can estimate AF burden. These technologies are already used to detect and monitor AF. This review describes the relation between AF burden and outcomes and potential effects of AF burden reduction. A lower AF burden is associated with a lower risk of stroke and heart failure in patients with AF: stroke risk without anticoagulation is lower in patients with device-detected AF and a low AF burden (stroke rate 1%/year) than in patients with persistent and permanent AF (stroke rate 3%/year). Paroxysmal AF shows intermediate stroke rates (2%/year). Atrial fibrillation burden-reducing interventions can reduce cardiovascular outcomes in patients with AF: early rhythm control reduces cardiovascular events including stroke and heart failure in patients with recently diagnosed AF and cardiovascular conditions. In patients with heart failure and AF, early rhythm control and AF ablation, interventions that reduce AF burden, reduce mortality and heart failure events. Recent technological innovations allow to estimate AF burden in clinical care, creating opportunities and challenges. While evidence remains limited, the existing data already suggest that AF burden reduction could be a therapeutic goal. In addition to anticoagulation and treatment of cardiovascular conditions, AF burden reduction emerges as a therapeutic goal. Future research will define the AF burden that constitutes a relevant risk of stroke and heart failure. Technologies quantifying AF burden need careful validation to advance the field.

The association of haemoglobin A1c variability with adverse outcomes in patients with atrial fibrillation prescribed anticoagulants. Eur J Prev Cardiol 2024:zwae249.

Abstract
AIMS The association of haemoglobin A1c (HbA1c) variability with the risk of adverse outcomes in patients with atrial fibrillation (AF) prescribed anticoagulants remains unclear. This study aimed to evaluate the association of HbA1c variability with the risk of ischaemic stroke (IS)/systemic embolism (SE) and all-cause mortality among patients with non-valvular AF prescribed anticoagulants. METHODS AND RESULTS Patients newly diagnosed with AF from 2013 to 2018 were included. Variability in HbA1c, indexed by the coefficient of variation (CV), was determined for those with at least three HbA1c measurements available from the time of study enrolment to the end of follow-up. To evaluate whether prevalent diabetes would modify the relationship between HbA1c variability and outcomes, participants were divided into diabetes and non-diabetes groups. The study included 8790 patients (mean age 72.7% and 48.5% female). Over a median follow-up of 5.5 years (interquartile range 5.2, 5.8), the incident rate was 3.74 per 100 person-years for IS/SE and 4.89 for all-cause mortality in the diabetes group. The corresponding incident rates in the non-diabetes group were 2.41 and 2.42 per 100 person-years. In the diabetes group, after adjusting for covariates including mean HbA1c, greater HbA1c variability was significantly associated with increased risk of IS/SE [hazard ratio (HR) = 1.65, 95% confidence interval (CI): 1.27-2.13) and all-cause mortality (HR = 1.24, 95% CI: 1.05-1.47) compared with the lowest CV tertile. A similar pattern was evident in the non-diabetes group (IS/SE: HR = 1.58, 95% CI: 1.23-2.02; all-cause mortality: HR = 1.35, 95% CI: 1.10-1.64). CONCLUSION Greater HbA1c variability was independently associated with increased risk of IS/SE and all-cause mortality among patients with AF, regardless of diabetic status.

Abstract
INTRODUCTION Both the prevalence of atrial fibrillation (AF) and its subsequent use of direct oral anticoagulants (DOACs) are rapidly increasing in patients of older age. In the absence of contra-indications, guidelines advocate anticoagulation based on the CHA2DS2-VASc score for all AF patients aged 75 and above. However, some practitioners are hesitant to prescribe anticoagulants to older and frail patients due to perceived elevated bleeding risks. This review delves into the comparative treatment outcomes of DOACs versus vitamin K antagonists (VKAs) in older patients with AF, particularly focusing on those of advanced age, frailty, increased risk of falling, chronic kidney disease (CKD), or with a history of major bleeding. Additionally, considerations on the use of off-label DOAC doses, the role of left atrial appendage (LAA) closure and future developments in factor XIa-inhibitors will be discussed. RESULTS While strong evidence supports the use of DOACs in the vital older patients with nonvalvular AF, it remains scant in frail patient groups. There is some evidence from non-randomized studies suggesting that the effect of DOACs compared with VKAs is consistent between frail and nonfrail patients. However, recent findings from a single randomized trial showed increased bleeding risks but comparable thromboembolic outcomes in frail individuals switching from VKAs to DOACs. In patients with an increased risk of falling, data suggest no relevant interaction of increased risk of falling on the effectiveness and safety of DOACs compared with warfarin. Resuming oral anticoagulants in patients with Af after major bleeding seems to be beneficial. Off-label low-dose DOAC is often prescribed to patients who were underrepresented in larger randomized trails because of an elevated risk of bleeding or overexposure to DOACs, but its effect on clinical outcomes remains uncertain. CONCLUSIONS DOACs are the recommended oral anticoagulant for vital older patients with AF. The scarcity of data backing DOAC use in frail individuals, those with renal impairments, or significant bleeding history underscores the necessity for further investigation. However, existing evidence suggests at least similar effectiveness and safety and potential benefits for DOACs in these patient subsets. Therefore, there is no reason to suggest these patients should be treated differently than the established guidelines regarding anticoagulation.

Abstract
AIMS The optimal antithrombotic therapy to balance the risk of thrombosis and bleeding in patients who undergo transcatheter aortic valve implantation (TAVI) is unknown. This systematic review/network meta-analysis of randomized controlled trials (RCTs) aimed to evaluate the efficacy and safety of different oral anticoagulant (OAC) and antiplatelet regimens in patients post-TAVI. METHODS AND RESULTS MEDLINE, Embase, CENTRAL, and ClinicalTrials.gov were searched from inception to April 2023. Co-primary outcomes were all-cause death and major bleeding. We conducted Bayesian network meta-analyses to compare all interventions simultaneously. For each outcome, we generated odds ratios (ORs) with 95% credible intervals using a random-effects model with informative priors, and ranked interventions based on mean surface under the cumulative ranking curve. We included 11 RCTs (n = 6415), including 1 unpublished RCT. Three trials enrolled patients with an indication for an OAC. Overall risk of bias was low or with some concerns. Median age was 81 years. Median follow-up was 6 months. The combination of OAC plus single antiplatelet therapy (SAPT) increased the risk of all-cause death compared with dual antiplatelet therapy (DAPT) (OR 1.78, 95% credible interval 1.15-2.77). No other comparisons for all-cause death were significantly different. For major bleeding, SAPT reduced the risk compared with DAPT, direct-acting OAC, and OAC + SAPT (OR 0.20-0.40), and DAPT reduced the risk compared with OAC + SAPT. SAPT and DAPT ranked best for all-cause death, while SAPT ranked best for major bleeding. CONCLUSION In post-TAVI patients, SAPT may provide the optimal balance of reducing thrombotic events while minimizing the risk of bleeding.

Abstract
Non-vitamin K antagonist oral anticoagulants (NOACs) are increasingly used for stroke prevention in atrial fibrillation. At the Asia Pacific Advancing Patient care with EdoXaban 2023 meeting, experts shared insights on gastrointestinal bleeding with NOACs for stroke prevention in atrial fibrillation in Asian clinical practice, where NOACs have gained widespread acceptance due to their favourable profiles. Gastrointestinal bleeding risk varies amongst NOACs, emphasizing the importance of diligent patient assessment, dosage selection and vigilant monitoring. Edoxaban emerged as a viable option with a low gastrointestinal bleeding risk profile in Asian compared with non-Asian patients, supporting its continued clinical utilization for appropriate patients.

Abstract
Atrial fibrillation (AF) prevalence increases in older patients which also show a high thromboembolic risk. Oral anticoagulants (OACs) are recommended to prevent cardioembolic events and direct oral anticoagulants (DOACs) improved anti-thrombotic treatment. However, the benefits/risks of anticoagulant in older patients still need to be completely defined. This retrospective observational study aimed to describe the treatment with OACs in older AF hospitalized patients, and to identify factors influencing OAC therapy or discontinuation using the REgistro Politerapie SIMI. Univariate and multivariate logistic regression models were applied to identify predictors of OACs treatment and discontinuation. Cox proportional hazards models were performed to evaluate one-year mortality by treatment groups. AF patients were 1,128(26.5 %) at discharge and 1,098(97.3 %) required OAC treatment; about half of them (N = 528;48.1 %) were no-OACs users; 236(21.5 %) and 334(30.4 %) used DOACs and VKA, respectively. Increasing DOACs use was observed during the study period. Predictors of OACs treatment were: BMI (OR:1.04; 95 %CI:1.01-1.07), Barthel index (OR:1.01; 95 %CI:1.01-1.02), medications number (OR:1.07; 95 %CI:1.01-1.13). Conversely, a lower probability was found in patients with a high CIR.S (OR:0.59; 95 %CI:0.36-0.97) and neoplasm (OR:0.57; 95 %CI:0.37-0.88). Hospital stay (OR:1.02; 95 %CI:1.01-1.05), neoplasm (OR:2.25; 95 %CI:1.07-4.70) and INR (OR:1.21; 95 %CI:1.05-1.40) increased OACs discontinuation. A lower discontinuation was observed in dyslipidemic patients (OR:0.18; 95 %CI:0.04-0.82) and heart failure (OR:0.38; 95 %CI:0.21-0.70). Among AF patients, 157(14.3 %) died during the follow-up year. Age (HR = 1.05; 95 %CI = 1.03-1.08) and CIR.S (HR = 2.54; 95 %CI = 1.53-4.21) were associated with a greater mortality risk. In conclusion, critical issues related to the underuse and discontinuation of OACs therapy in hospitalized older patients were highlighted.

Abstract
Background The All Nippon Atrial Fibrillation In the Elderly Registry provides real-world insights into non-valvular atrial fibrillation (NVAF) in >30,000 elderly Japanese patients (aged ≥75 years), including >2,000 nonagenarians. We aimed to investigate outcomes in these patients by age and oral anticoagulant (OAC) type. Methods and Results This prospective, multicenter, observational, cohort, 2-year follow-up study included elderly patients with NVAF who were able to attend hospital visits. The incidences of stroke/systemic embolic events (SEE), major bleeding, intracranial hemorrhage (ICH), cardiovascular death, all-cause death, and major adverse cardiovascular or neurological events (MACNE) were evaluated by age. Incidence rates increased significantly with age. Stroke/SEE, major bleeding, and ICH incidences plateaued in patients aged ≥90 years. Direct OACs (DOACs) yielded a numerically lower event incidence vs. warfarin in all age groups and endpoints, except for major bleeding in patients aged ≥90 years. DOACs (vs. warfarin) were significantly associated with a lower risk of stroke/SEE, major bleeding, and ICH in the ≥80-<85 years group, and reduced cardiovascular and all-cause death in the ≥75-<80 years group. In the ≥90 years subgroup, major bleeding history was a risk factor for all-cause death. Conclusions Although DOAC vs. warfarin offers potential benefits for stroke prevention, limitations occurred in reducing major bleeding among those aged ≥90 years, indicating a potential benefit of very-low-dose DOAC for this demographic.

Abstract
OBJECTIVES The aim of the study was to determine the prevalence of AF in the cardiology department of the Hospital Principal of Dakar, then to evaluate the clinical, paraclinical, etiological and evolutionary profiles of AF and finally to identify the limits of its management in our context. PATIENTS AND METHODS This was a retrospective, descriptive, analytical, mono-centric study carried out at Hospital Principal of Dakar from January 2019 to August 2021. Were included, all patients admitted for atrial fibrillation, or patients who presented an atrial fibrillation during hospitalization, confirmed by electrocardiogram or long-term electrocardiographic recording during the study period. RESULTS The prevalence of atrial fibrillation during the period of our study compared to the hospital population was 7.71%, with a sex ratio of 1.03. The mean age was 67.88 ± 14.09 years. We noted that 83.64% of patients had at least one cardiovascular risk factor, with 56.36% suffering from hypertension, 50.91% of sedentary person and 23.64% of diabetics. Clinically, 92.72% of the patients were symptomatic, with dyspnea predominating (70.91%). Cardiac arrhythmia was present in 85.45% of patients, and congestive heart failure in 47.27%. Long-term electrocardiographic recording was performed in 10 patients, showing 50% of paroxysmal atrial fibrillation. Sixty-three patients (57.27%) had permanent AF, twenty-three patients (20.91%) had persistent AF, fourteen patients (12.73%) had long-term persistent AF and ten patients (9.09%) had paroxysmal AF. Transthoracic echocardiography showed 57.27% of left atrial dilatation and 72.3% of reduced left ventricular ejection fraction. Etiologies for cardiac causes were dominated by dilated cardiomyopathy (21.82%), followed by ischemic heart disease (17.27%). In terms of treatment, the most commonly used molecule was bisoprolol (38.18%), followed by digoxin (21.81%). Anticoagulants were used in 85.46% of cases. Acenocoumarol alone was used in 69.09% of patients. Drug-induced cardioversion was attempted in 2 patients without success, and 4 patients benefited from external electric shock with 3 successes. Most patients had a favorable outcome, but 34.54% suffered hemodynamic complications (18.18%) and thromboembolic ones as well (16.36%). In-hospital mortality in our series was 20%. It was significantly related to heart failure, with a left ventricular ejection fraction < 35% (p < 0.001). CONCLUSION Atrial fibrillation is serious because of its hemodynamic, thromboembolic and rhythmic complications. The high mortality is explained by the underlying condition, but also by the delay in management with late diagnosis and, above all, the unavailability of ablation procedures in our context.

Abstract
BACKGROUND While direct-acting oral anticoagulants (DOACs) have established efficacy in reducing the risk of ischemic stroke, they still leave a residual risk of stroke, which may be greater in practice (0.7-2.3%) than in controlled clinical trial settings. This meta-analysis examines four therapeutic approaches following a stroke in patients already on DOACs: continuing with the same DOAC, changing to a different DOAC, increasing the current DOAC dosage, or switching to a vitamin K antagonist (VKA), such as warfarin. METHODS Systematic review of literature from the MEDLINE, Embase, and Cochrane databases, was conducted in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The analysis focused on six studies with varied patient demographics, examining as outcomes as recurrent ischemic stroke, intracranial hemorrhage, other bleeding events, and mortality. RESULTS Six studies comprising 12,159 patients were included, all of them were observational. Patients who remained on their initial DOAC regimen had a lower risk of experiencing ischemic strokes (risk ratio (RR) 0.55; 95% confidence interval (CI) 0.43-0.70; p < 0.001; I2 = 0%), intracranial hemorrhage (RR 0.37; 95% CI 0.25-0.55; p < 0.001; I2 = 0%), and hemorrhagic events (RR 0.44; 95% CI 0.30-0.63; p < 0.001; I2 = 6%) compared to those who were switched to warfarin, with an increase in mortality rates (hazard ratio (HR) 1.85; 95% CI 1.06-3.24; p = 0.03; I2 = 84%). In contrast, neither changing to a different DOAC nor adjusting the dose proved to be more effective than the original regimen. CONCLUSION Post-stroke adjustments to anticoagulation therapy-whether altering the drug or its dosage-do not yield additional benefits. In addition, the results suggest that warfarin may be less effective than DOACs for preventing stroke recurrence, bleeding complications, and death in this patient population.

Abstract
The nuanced landscape of anticoagulation therapy in patients with chronic kidney disease (CKD) presents a formidable challenge, intricately balancing the dual hazards of hemorrhage and thrombosis. These patients find themselves in a precarious position, teetering on the edge of these risks due to compromised platelet functionality and systemic disturbances within their coagulation frameworks. The management of such patients necessitates a meticulous approach to dosing adjustments and vigilant monitoring to navigate the perilous waters of anticoagulant therapy. This is especially critical considering the altered pharmacokinetics in CKD, where the clearance of drugs is significantly impeded, heightening the risk of accumulation and adverse effects. In the evolving narrative of anticoagulation therapy, the introduction of direct oral anticoagulants (DOACs) has heralded a new era, offering a glimmer of hope for those navigating the complexities of CKD. These agents, with their promise of easier management and a reduced need for monitoring, have begun to reshape the contours of care, particularly for patients not yet on dialysis. However, this is not without its caveats. The application of DOACs in the context of advanced CKD remains a largely uncharted territory, necessitating a cautious exploration to unearth their true potential and limitations. Moreover, the advent of innovative strategies such as left atrial appendage occlusion (LAAO) underscores the dynamic nature of anticoagulation therapy, potentially offering a tailored solution for those at the intersection of CKD and elevated stroke risk. Yet the journey toward integrating such advancements into standard practice is laden with unanswered questions, demanding rigorous investigation to illuminate their efficacy and safety across the spectrum of kidney disease. In summary, the management of anticoagulation in CKD is a delicate dance, requiring a harmonious blend of precision, caution, and innovation. As we venture further into this complex domain, we must build upon our current understanding, embracing both emerging therapies and the need for ongoing research. Only then can we hope to offer our patients a path that navigates the narrow strait between bleeding and clotting, toward safer and more effective care.

Abstract
BACKGROUND AND AIMS This study aimed to evaluate clinical outcomes in patients developing post-operative atrial fibrillation (POAF) after coronary artery bypass grafting (CABG) and characterize variations in oral anticoagulation (OAC) use, benefits, and complications. METHODS A systematic search identified studies on new-onset POAF after CABG and OAC initiation. Outcomes included risks of thromboembolic events, bleeding, and mortality. Furthermore, a meta-analysis was conducted on these outcomes, stratified by the use or non-use of OAC. RESULTS The identified studies were all non-randomized. Among 1 698 307 CABG patients, POAF incidence ranged from 7.9% to 37.6%. Of all POAF patients, 15.5% received OAC. Within 30 days, thromboembolic events occurred at rates of 1.0% (POAF: 0.3%; non-POAF: 0.8%) with 2.0% mortality (POAF: 1.0%; non-POAF: 0.5%). Bleeding rates were 1.1% for POAF patients and 2.7% for non-POAF patients. Over a median of 4.6 years, POAF patients had 1.73 thromboembolic events, 3.39 mortality, and 2.00 bleeding events per 100 person-years; non-POAF patients had 1.14, 2.19, and 1.60, respectively. No significant differences in thromboembolic risks [effect size -0.11 (-0.36 to 0.13)] and mortality [effect size -0.07 (-0.21 to 0.07)] were observed between OAC users and non-users. However, OAC use was associated with higher bleeding risk [effect size 0.32 (0.06-0.58)]. CONCLUSIONS In multiple timeframes following CABG, the incidence of complications in patients who develop POAF is low. The use of OAC in patients with POAF after CABG is associated with increased bleeding risk.

Abstract
Atrial fibrillation (AF) prediction and screening are of important clinical interest because of the potential to prevent serious adverse events. Devices capable of detecting short episodes of arrhythmia are now widely available. Although it has recently been suggested that some high-risk patients with AF detected on implantable devices may benefit from anticoagulation, long-term management remains challenging in lower-risk patients and in those with AF detected on monitors or wearable devices as the development of clinically meaningful arrhythmia burden in this group remains unknown. Identification and prediction of clinically relevant AF is therefore of unprecedented importance to the cardiologic community. Family history and underlying genetic markers are important risk factors for AF. Recent studies suggest a good predictive ability of polygenic risk scores, with a possible additive value to clinical AF prediction scores. Artificial intelligence, enabled by the exponentially increasing computing power and digital data sets, has gained traction in the past decade and is of increasing interest in AF prediction using a single or multiple lead sinus rhythm electrocardiogram. Integrating these novel approaches could help predict AF substrate severity, thereby potentially improving the effectiveness of AF screening and personalizing the management of patients presenting with conditions such as embolic stroke of undetermined source or subclinical AF. This review presents current evidence surrounding deep learning and polygenic risk scores in the prediction of incident AF and provides a futuristic outlook on possible ways of implementing these modalities into clinical practice, while considering current limitations and required areas of improvement.

Abstract
Hintergrund Orale Nicht-Vitamin-K-Antikoagulanzien (NOAKs) sind sicher und wirksam in der Schlaganfallprävention bei Patienten mit Vorhofflimmern (AF). Es gibt jedoch nur wenige Daten zur Sicherheit und Wirksamkeit der oralen Antikoagulation mit Edoxaban im deutschsprachigen Raum in der Routineversorgung. Wir berichten über die Ein-Jahres-Ergebnisse der Patienten, die in Deutschland, Österreich und der Schweiz (DACH) im Rahmen der ETNA-AF-Europa-Studie mit Edoxaban zur Schlaganfallprävention behandelt wurden. Methoden Die ETNA-AF-Europa-Studie (Clinicaltrials.gov:NCT02 944 019) ist eine multizentrische, prospektive Beobachtungsstudie, in die mit Edoxaban zur Schlaganfallprävention bei AF behandelte Patienten (n = 13 092) aus 852 Zentren in 10 europäischen Ländern aufgenommen wurden. Die DACH-Kohorte besteht aus 5457 (41,7 %) Patienten aus Zentren in Deutschland, Österreich und der Schweiz. Resultate Die Patienten (74 Jahre, 2384 [44 %] Frauen) hatten im Mittel einen CHA 2 DS 2 -VASc-Score von 3,2 ± 1,4 – und eine labelkonforme Dosierung von Edoxaban wurde von 4309 Patienten (78,9 %) eingenommen. Nach einem Beobachtungszeitraum von einem Jahr traten bei 42 Patienten (0,8 %/Jahr) ein Schlaganfall oder ein systemisch embolisches Ereignis auf, und bei 36 Patienten (0,7 %/Jahr) kam es zu einem schweren Blutungsereignis, was bei 10 Patienten (0,2 %/Jahr) auf eine intrakranielle Blutung und bei 13 Patienten (0,3 %/Jahr) auf eine schwere gastrointestinale (GI) Blutung zurückzuführen war. Schwere und klinisch relevante, nicht schwere Blutungen zusammengenommen ereigneten sich bei insgesamt 72 Patienten (1,4 %/Jahr) über den Beobachtungszeitraum. Die Gesamtmortalität lag bei 179 Patienten (3,4 %/Jahr), wobei 85 (1,6 %/Jahr) an einer kardiovaskulären Todesursache verstarben. Bei Patienten mit einem erhöhten Lebensalter, einem gebrechlichen Allgemeinzustand, einem CHA 2 DS 2 -VASc-Score ≥ 4 zeigten sich eine höhere Gesamtmortalität und eine höhere Rate von Schlaganfällen sowie schweren Blutungsereignissen. Schlussfolgerung In Deutschland, Österreich und der Schweiz ist die Ereignisrate der Schlaganfälle und schweren Blutungen bei Patienten, die zur Schlaganfallprävention bei AF mit Edoxaban behandelt wurden, niedrig. Eine zunehmende Morbidität geht mit einer höheren Rate der relevanten klinischen Endpunkte einher.

Abstract
The prevention of thromboembolism in atrial fibrillation (AF) is typically restricted to patients with specific risk factors and ignores outcomes such as vascular dementia. This population-based cohort study used electronic healthcare records from 5,199,994 primary care patients (UK; 2005-2020). A total of 290,525 (5.6%) had a diagnosis of AF and were aged 40-75 years, of which 36,340 had no history of stroke, a low perceived risk of stroke based on clinical risk factors and no oral anticoagulant prescription. Matching was performed for age, sex and region to 117,298 controls without AF. During 5 years median follow-up (831,005 person-years), incident stroke occurred in 3.8% with AF versus 1.5% control (adjusted hazard ratio (HR) 2.06, 95% confidence interval (CI) 1.91-2.21; P < 0.001), arterial thromboembolism 0.3% versus 0.1% (HR 2.39, 95% CI 1.83-3.11; P < 0.001), and all-cause mortality 8.9% versus 5.0% (HR 1.44, 95% CI 1.38-1.50; P < 0.001). AF was associated with all-cause dementia (HR 1.17, 95% CI 1.04-1.32; P = 0.010), driven by vascular dementia (HR 1.68, 95% CI 1.33-2.12; P < 0.001) rather than Alzheimer's disease (HR 0.85, 95% CI 0.70-1.03; P = 0.09). Death and thromboembolic outcomes, including vascular dementia, are substantially increased in patients with AF despite a lack of conventional stroke risk factors.

Impact of gender in patients with device-related thrombosis after left atrial appendage closure - A sub-analysis from the multicenter EUROC-DRT-registry. Echocardiography 2024; 41:e15888.

Abstract
BACKGROUND Device-related thrombosis (DRT) is a common finding after left atrial appendage closure (LAAC) and is associated with worse outcomes. As women are underrepresented in clinical studies, further understanding of sex differences in DRT patients is warranted. METHODS AND RESULTS This sub-analysis from the EUROC-DRT-registry compromises 176 patients with diagnosis of DRT after LAAC. Women, who accounted for 34.7% (61/176) of patients, were older (78.0 ± 6.7 vs. 74.9 ± 9.1 years, p = .06) with lower rates of comorbidities. While DRT was detected significantly later in women (173 ± 267 vs. 127 ± 192 days, p = .01), anticoagulation therapy was escalated similarly, mainly with initiation of novel oral anticoagulant (NOAC), vitamin K antagonist (VKA) or heparin. DRT resolution was achieved in 67.5% (27/40) of women and in 75.0% (54/72) of men (p = .40). In the remaining cases, an intensification/switch of anticoagulation was conducted in 50.% (9/18) of men and in 41.7% (5/12) of women. Final resolution was achieved in 72.5% (29/40) cases in women, and in 81.9% (59/72) cases in men (p = .24). Women were followed-up for a similar time as men (779 ± 520 vs. 908 ± 687 days, p = .51). Kaplan-Meier analysis revealed no difference in mortality rates in women (Hazard Ratio [HR]: 1.73, 95%-Confidence interval [95%-CI]: .68-4.37, p = .25) and no differences in stroke (HR: .83, 95%-CI: .30-2.32, p = .72) within 2 years after LAAC. CONCLUSION Evaluation of risk factors and outcome revealed no differences between men and women, with DRT in women being diagnosed significantly later. Women should be monitored closely to assess for DRT formation/resolution. Treatment strategies appear to be equally effective.

Long-term effectiveness and safety of edoxaban in patients with atrial fibrillation: 4-year data from the ETNA-AF-Europe study. Int J Cardiol 2024; 408:132118. [PMID: 38697397 DOI: 10.1016/j.ijcard.2024.132118] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 03/28/2024] [Accepted: 04/29/2024] [Indexed: 05/05/2024]
Abstract
BACKGROUND To assess long-term effectiveness and safety of edoxaban in Europe. METHODS AND RESULTS ETNA-AF-Europe, a prospective, multinational, multi-centre, post-authorisation, observational study was conducted in agreement with the European Medicines Agency. The primary and secondary objectives assessed real-world safety (including bleeding and deaths) and effectiveness (including stroke, systemic embolic events and clinical edoxaban use), respectively. Median (interquartile range) age of the 13,164 patients was 75.0 (68.0-80.0) years; CHA2DS2-VASc and HAS-BLED scores were 3.0 (2.0-4.0) and 2.0 (1.0-2.0), respectively. Follow-up duration was 3.98 (3.21-4.05) years. Patients on edoxaban 30 mg (n = 3042) at baseline were older (80.0 vs 73.0 years), more likely assessed as frail by investigators (27.0% vs 6.6%) and had more comorbidities than those on edoxaban 60 mg (n = 9617; missing dosing information for n = 505). Annualised event rates of all-cause and cardiovascular death in the overall population, edoxaban 60 mg and edoxaban 30 mg groups were 4.1%, 2.8% and 8.4%, and 1.0%, 0.7% and 2.0%, respectively. Annualised rates of stroke were relatively constant throughout the follow-up, transient ischaemic attack and systemic embolism were < 1% in the overall population. Rates of any major and major gastrointestinal bleeding were low, with slightly higher rates for edoxaban 30 vs 60 mg group. Intracranial haemorrhage was uncommon (0.2%). CONCLUSIONS In European patients with AF, long-term therapy with edoxaban is associated with low and relatively constant annualised rates of stroke and major bleeding. Differences in outcomes between the two approved doses are attributable to differences in clinical characteristics.

Abstract
In the last three decades, ablation of atrial fibrillation (AF) has become an evidence-based safe and efficacious treatment for managing the most common cardiac arrhythmia. In 2007, the first joint expert consensus document was issued, guiding healthcare professionals involved in catheter or surgical AF ablation. Mounting research evidence and technological advances have resulted in a rapidly changing landscape in the field of catheter and surgical AF ablation, thus stressing the need for regularly updated versions of this partnership which were issued in 2012 and 2017. Seven years after the last consensus, an updated document was considered necessary to define a contemporary framework for selection and management of patients considered for or undergoing catheter or surgical AF ablation. This consensus is a joint effort from collaborating cardiac electrophysiology societies, namely the European Heart Rhythm Association, the Heart Rhythm Society (HRS), the Asia Pacific HRS, and the Latin American HRS.

Abstract
The left atrial appendage (LAA) has gained increasing attention in the field of cardiology as a potential site for intervention in patients with atrial fibrillation (AF) and an elevated risk of thromboembolic events. Left atrial appendage occlusion (LAAO) has emerged as a promising therapeutic strategy to mitigate the risk of stroke and systemic embolism, especially in individuals who are unsuitable candidates for long-term anticoagulation therapy. This review aims to provide a comprehensive analysis of the current state of LAAO, encompassing its anatomic considerations, procedural techniques, clinical outcomes, and future directions.

Abstract
INTRODUCTION There is a paucity of real-world studies examining the risks of stroke/systemic embolism (SE) and major bleeding (MB) among non-valvular atrial fibrillation (NVAF) patients switching from warfarin to a direct oral anticoagulant (DOAC). This retrospective study was conducted to compare the stroke/SE and MB risks between patients switched from warfarin to apixaban, dabigatran, or rivaroxaban in real-world clinical practice. MATERIALS AND METHODS This study used data from four United States commercial claims databases from January 1, 2012 to June 30, 2019. The study population included NVAF patients initially treated with warfarin and switched to apixaban, dabigatran, or rivaroxaban within 90 days of their warfarin prescription ending. Patients were matched 1:1 between the DOACs in each database using propensity scores and then pooled for the final analysis. Cox proportional hazards models were used to calculate the risk of stroke/SE and MB. RESULTS AND CONCLUSIONS The final population consisted of 2,611 apixaban-dabigatran, 12,165 apixaban-rivaroxaban, and 2,672 dabigatran-rivaroxaban pairs. Apixaban vs. dabigatran was associated with a lower risk of stroke/SE (hazard ratio [HR]: 0.61; 95% confidence interval [CI]: 0.39-0.96) and MB (HR: 0.67; 95% CI: 0.50-0.91). Apixaban vs. rivaroxaban was associated with a similar risk of stroke/SE (HR: 0.88; 95% CI: 0.73-1.07) and a lower risk of MB (HR: 0.60; 95% CI: 0.52-0.68). There was no significant difference in either risk between dabigatran and rivaroxaban. These results provide important insights into how the risks of stroke/SE and MB for NVAF patients vary when switching from warfarin to different DOACs.

Abstract
INTRODUCTION Oral anticoagulation (OAC) is key in atrial fibrillation (AF) thromboprophylaxis, but Spain lacks substantial real-world evidence. We aimed to analyze the prevalence, clinical characteristics, and treatment patterns among patients with AF undertaking OAC, using natural language processing (NLP) and machine learning (ML). MATERIALS AND METHODS This retrospective study included AF patients on OAC from 15 Spanish hospitals (2014-2020). Using EHRead® (including NLP and ML), and SNOMED_CT, we extracted and analyzed patient demographics, comorbidities, and OAC treatment from electronic health records. AF prevalence was estimated, and a descriptive analysis was conducted. RESULTS Among 4,664,224 patients in our cohort, AF prevalence ranged from 1.9% to 2.9%. A total of 57,190 patients on OAC therapy were included, 80.7% receiving Vitamin K antagonists (VKA) and 19.3% Direct-acting OAC (DOAC). The median age was 78 and 76 years respectively, with males constituting 53% of the cohort. Comorbidities like hypertension (76.3%), diabetes (48.0%), heart failure (42.2%), and renal disease (18.7%) were common, and more frequent in VKA users. Over 50% had a high CHA2DS2-VASc score. The most frequent treatment switch was from DOAC to acenocoumarol (58.6% to 70.2%). In switches from VKA to DOAC, apixaban was the most chosen (35.2%). CONCLUSIONS Utilizing NLP and ML to extract RWD, we established the most comprehensive Spanish cohort of AF patients with OAC to date. Analysis revealed a high AF prevalence, patient complexity, and a marked VKA preference over DOAC. Importantly, in VKA to DOAC transitions, apixaban was the favored option.

Abstract
The world's population is ageing, with the number of those over 60 years expected to represent a fifth of the total population by 2050. Increases in chronic long-term health conditions (LTCs) associated with ageing, and requiring regular but often avoidable medical intervention, are pressurising already overloaded, health and social care systems. Atrial fibrillation (AF) is an LTC, which is most frequently diagnosed in the elderly. An often, asymptomatic condition, AF is associated with a 3- to 5-fold increased risk of severe ischemic stroke. Stroke prevention, with risk-stratified oral anticoagulants (OACs) is the standard recommended care for patients with AF. Stroke avoidance is, however, dependent on persistent adherence to OAC medication, with an adherence rate of >80% considered necessary to achieve optimal health outcomes. Suboptimal adherence to OACs is common, with a third of all AF patients not taking their medication as prescribed. This combined with the short half-life of OACs can result in poor clinical outcomes for patients. Policy makers now consider improving adherence to prescribed medicines for LTCs, a public health priority, to ensure better health outcomes for patients, whilst minimising unnecessary health system costs. Prescribing medicines to treat LTCs, such as AF, is not enough, particularly when the patient may not experience any measurable benefit to the treatment and may instead, experience medication-associated adverse events, including a risk of bleeding. Pharmacists who are experts in medicines management are ideally placed to support medication adherence, to educate, and to improve health outcomes for patients with AF. In this review, I will consider the evidence for poor medication adherence in LTCs and in particular adherence to OACs in patients with AF and highlight the role that pharmacists can play in ensuring optimal adherence and showcase pharmacist-led interventions that effectively address this problem.

Abstract
The efficacy and safety of direct oral anticoagulants (DOAC) in patients with embolic stroke of undetermined source (ESUS) remains unclear. We systematically searched PubMed, Embase, and Cochrane Library for randomized controlled trials (RCT) comparing DOACs versus aspirin in patients with ESUS. Risk ratios (RR) and 95% confidence intervals (CI) were computed for binary endpoints. Four RCTs comprising 13,970 patients were included. Compared with aspirin, DOACs showed no significant reduction of recurrent stroke (RR 0.95; 95% CI 0.84-1.09; p = 0.50; I2 = 0%), ischemic stroke or systemic embolism (RR 0.97; 95% CI 0.80-1.17; p = 0.72; I2 = 0%), ischemic stroke (RR 0.92; 95% CI 0.79-1.06; p = 0.23; I2 = 0%), and all-cause mortality (RR 1.11; 95% CI 0.87-1.42; p = 0.39; I2 = 0%). DOACs increased the risk of clinically relevant non-major bleeding (CRNB) (RR 1.52; 95% CI 1.20-1.93; p < 0.01; I2 = 7%) compared with aspirin, while no significant difference was observed in major bleeding between groups (RR 1.57; 95% CI 0.87-2.83; p = 0.14; I2 = 63%). In a subanalysis of patients with non-major risk factors for cardioembolism, there is no difference in recurrent stroke (RR 0.98; 95% CI 0.67-1.42; p = 0.90; I2 = 0%), all-cause mortality (RR 1.24; 95% CI 0.58-2.66; p = 0.57; I2 = 0%), and major bleeding (RR 1.00, 95% CI 0.32-3.08; p = 1.00; I2 = 0%) between groups. In patients with ESUS, DOACs did not reduce the risk of recurrent stroke, ischemic stroke or systemic embolism, or all-cause mortality. Although there was a significant increase in clinically relevant non-major bleeding, major bleeding was similar between DOACs and aspirin.

Abstract
Objectives To analyze the clinical profile, adequacy of treatment with rivaroxaban and outcomes in octogenarians with atrial fibrillation (AF), taking rivaroxaban in clinical practice. Methods Observational and non-interventional study that included AF adults recruited from 79 Spanish centers, anticoagulated with rivaroxaban ≥ 6 months before being included. Data were analyzed according to age (≥ 80 vs. < 80 years) at baseline. Results Out of 1433 patients, 453 (31.6%) were octogenarians at baseline. Compared to younger patients, octogenarians had more comorbidities, higher CHA2DS2-VASc (4.5 ± 1.3 vs. 3.0 ± 1.4; P < 0.001) and HAS-BLED scores (2.0 ± 1.0 vs. 1.4 ± 1.0; P < 0.001). Overall, the dose of rivaroxaban was adequately prescribed in 83.4% of patients, but more frequently in the younger population (71.1% vs. 89.1%; P = 0.039). After a mean follow-up of 2.2 ± 0.6 years, annual rates of stroke + systemic embolism + transient ischemic attack, MACE, cardiovascular death and major bleeding were 1.03%, 1.24%, 1.03% and 1.75%, respectively, in octogenarian patients. Except for progressive heart failure death and major bleeding, rates of outcomes in octogenarians were similar compared to younger patients. In octogenarians, the concomitant use of antiplatelet agents and non-severe dementia were independently associated with the development of ischemic stroke, whereas previous coronary revascularization and heart failure with MACE, and higher HAS-BLED score with major bleeding. Conclusions In clinical practice, around one third of patients taking rivaroxaban are octogenarians. These patients have many comorbidities and a high thromboembolic risk. Despite that, rates of adverse events remain low. Rivaroxaban is adequately prescribed in the majority of octogenarians.

Abstract
BACKGROUND Acute limb ischemia (ALI) is a morbid and deadly diagnosis. However, existing epidemiologic studies describing ALI predate the introduction of the Affordable Care Act in 2010 and direct oral anticoagulants in 2011. Thus, we synergized the National Inpatient Sample (NIS) and United States Census to define contemporary trends in the incidence, treatment, and outcomes of ALI in the US. METHODS We included emergent admissions of adults with primary diagnosis of lower extremity ALI in survey-weighted NIS data (2005-2020). Mann-Kendal trend test evaluated ALI incidence (primary outcome), anticoagulation usage, insurance coverage, revascularization type, and in-hospital amputation/death. Multivariable logistic regression quantified covariate associations with in-hospital amputation/death. RESULTS Of the 582,322,862 estimated hospitalizations in the NIS, 227,440 met the inclusion criteria (mean age 68.80 years, 49.94% women, 76.66% White). ALI incidence peaked in 2006 (7.16/100,000 person-years) but has declined since 2015 to 4.16/100,000 person-years in 2020 (ptrend = 0.008). Endovascular revascularization, anticoagulation, and Medicaid coverage increased, while self-pay insurance decreased (ptrend < 0.05). Amputation rates significantly decreased from 8.04 to 6.54% (ptrend = 0.01) while death rate remained at 5.59% (ptrend = 0.16) over the study period. Prehospitalization anticoagulation was associated with decreased amputation (adjusted odds ratio [aOR] = 0.74 (95% confidence interval [CI] 0.65-0.84)) and death (aOR = 0.50 (95% CI 0.43-0.57)). When controlling for covariates, women had a higher risk of death (aOR = 1.17 (95% CI 1.07-1.27), P < 0.0001), while Black patients had a higher risk of amputation (aOR = 1.24 (95% CI 1.10-1.41), P < 0.0001). CONCLUSIONS Our US population based epidemiological study demonstrates that ALI incidence and in-hospital amputation rates are decreasing, while mortality remains unchanged. We further highlight the ongoing need for ALI investigation specifically as it relates to access to care, antithrombotic therapy use, treatment strategy, and strategies to combat gender and racial disparities.

Abstract
BACKGROUND ARTESiA (Apixaban for the Reduction of Thrombo-Embolism in Patients With Device-Detected Sub-Clinical Atrial Fibrillation) demonstrated that apixaban, compared with aspirin, significantly reduced stroke and systemic embolism (SE) but increased major bleeding in patients with subclinical atrial fibrillation. OBJECTIVES To help inform decision making, the authors evaluated the efficacy and safety of apixaban according to baseline CHA2DS2-VASc score. METHODS We performed a subgroup analysis according to baseline CHA2DS2-VASc score and assessed both the relative and absolute differences in stroke/SE and major bleeding. RESULTS Baseline CHA2DS2-VASc scores were <4 in 1,578 (39.4%) patients, 4 in 1,349 (33.6%), and >4 in 1,085 (27.0%). For patients with CHA2DS2-VASc >4, the rate of stroke was 0.98%/year with apixaban and 2.25%/year with aspirin; compared with aspirin, apixaban prevented 1.28 (95% CI: 0.43-2.12) strokes/SE per 100 patient-years and caused 0.68 (95% CI: -0.23 to 1.57) major bleeds. For CHA2DS2-VASc <4, the stroke/SE rate was 0.85%/year with apixaban and 0.97%/year with aspirin. Apixaban prevented 0.12 (95% CI: -0.38 to 0.62) strokes/SE per 100 patient-years and caused 0.33 (95% CI: -0.27 to 0.92) major bleeds. For patients with CHA2DS2-VASc =4, apixaban prevented 0.32 (95% CI: -0.16 to 0.79) strokes/SE per 100 patient-years and caused 0.28 (95% CI: -0.30 to 0.86) major bleeds. CONCLUSIONS One in 4 patients in ARTESiA with subclinical atrial fibrillation had a CHA2DS2-VASc score >4 and a stroke/SE risk of 2.2% per year. For these patients, the benefits of treatment with apixaban in preventing stroke/SE are greater than the risks. The opposite is true for patients with CHA2DS2-VASc score <4. A substantial intermediate group (CHA2DS2-VASc =4) exists in which patient preferences will inform treatment decisions.

Abstract
PURPOSE OF REVIEW This review provides an overview of the factor XI (FXI) inhibitor hypothesis for the development of novel anticoagulants which may be safer to those currently used in clinical practice and describes preliminary clinical data from phase 2 dose-ranging studies of patients with atrial fibrillation. RECENT FINDINGS Recent data from phase 2 dose ranging studies demonstrate substantial reductions in bleeding with FXI pathway inhibition compared with currently approved anticoagulants. However, larger studies are necessary to demonstrate efficacy of FXI inhibition for stroke prevention in atrial fibrillation. FXI pathway inhibition holds great promise for revolutionizing the landscape of anticoagulation for atrial fibrillation, primarily by reducing bleeding risk; however, further data are necessary to demonstrate efficacy.

Abstract
Aims: Our aims were to describe the clinical characteristics, adverse clinical events, healthcare resource utilization (HCRU) and costs of patients with major bleeding during direct Factor Xa inhibitor (FXai) use. Methods: This is a retrospective cohort study that included secondary data from computerized health records of seven Spanish Autonomous Communities. Patients with a first major bleeding during treatment with a direct FXai were analyzed during a 3-year period. Results: Of 8972 patients taking a direct FXai, 470 (5.24%) had major bleeding (mean age (SD) 77.93 (9.71) years, 61.06% women). The most frequent indications for using FXais were atrial fibrillation (78.09%) and venous thromboembolism (17.66%). Among those with major bleeding, 88.94% presented with gastrointestinal bleeding, 6.81% intracranial bleeding, 2.13% trauma-related bleeding and 4.26% other major bleeding. Prothrombin complex concentrates were used in 63.19%, followed by transfusion of blood products (20.21%) and Factor VIIa (7.66%). In total, 4.26% of patients died in the hospital due to the first major bleeding. At the study end (after 3-year follow-up), 28.94% of the patients had died, 12.34% had a myocardial infarction and 9.15% an ischemic stroke. At year 3, overall bleeding cost was EUR 5,816,930.5, of which 79.74% accounted for in-hospital costs to treat the bleeding episode. Conclusions: Despite the use of replacement agents being high, major events were common, with a 29% mortality at the end of the follow up, and HCRU and costs were high, evidencing the need for new reversal treatment strategies.

BACKGROUND Nursing home residents with atrial fibrillation are at high risk for ischemic stroke, but most are not treated with anticoagulants. This study compared the effectiveness and safety between oral anticoagulant (OAC) users and non-users. METHODS We conducted a new-user retrospective cohort study by using Minimum Data Set 3.0 assessments linked with Medicare claims. The participants were Medicare fee-for-service beneficiaries with atrial fibrillation residing in US nursing homes between 2011 and 2016, aged ≥ 65 years. The primary outcomes were occurrence of an ischemic stroke or systemic embolism (effectiveness), occurrence of intracranial or extracranial bleeding (safety) and net clinical outcome (effectiveness or safety outcomes). Secondary outcomes included total mortality and a net clinical and mortality outcome. Cox proportional hazards and Fine and Grey models estimated multivariable adjusted hazard ratios (aHRs) and sub-distribution hazard ratios (sHRs). RESULTS Outcome rates were low (effectiveness: OAC: 0.86; non-users: 1.73; safety: OAC: 2.26; non-users: 1.75 (per 100 person-years)). OAC use was associated with a lower rate of the effectiveness outcome (sHR: 0.69; 95% Confidence Interval (CI): 0.61-0.77), higher rates of the safety (sHR: 1.70; 95% CI: 1.58-1.84) and net clinical outcomes (sHR: 1.20; 95% CI: 1.13-1.28) lower rate of all-cause mortality outcome (sHR: 0.60; 95% CI: 0.59-0.61), and lower rate of the net clinical and mortality outcome (sHR: 0.60; 95% CI: 0.59-0.61). Warfarin users, but not DOAC users, had a higher rate of the net clinical outcome versus OAC non-users. CONCLUSIONS Our results support the benefits of treatment with OACs to prevent ischemic strokes and increase longevity, while highlighting the need to weigh apparent benefits against elevated risk for bleeding. Results were consistent with net favorability of DOACs versus warfarin.

Sex-specific comparative outcomes between oral anticoagulants in patients with atrial fibrillation: a systematic review and meta-analysis. Open Heart 2024; 11:e002792. [PMID: 39019498 PMCID: PMC11253745 DOI: 10.1136/openhrt-2024-002792] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2024] [Accepted: 07/02/2024] [Indexed: 07/19/2024] Open
Abstract
AIMS Women with atrial fibrillation (AF) are under-represented in randomised controlled trials (RCTs) of direct oral anticoagulants (DOACs). This systematic review and meta-analysis of RCTs and observational studies examined sex-specific outcomes of DOACs in AF. METHODS PubMed, Embase, Web of Science and Cochrane Library were searched from January 2008 to November 2022. Sex-specific comparative outcomes of stroke/systemic embolism (SE), major bleeding, intracranial haemorrhage (ICH) and gastrointestinal bleeding (GIB) between oral anticoagulants were pooled using random effects models. P values for interaction were calculated to examine differences in results between sexes. RCTs and observational studies were meta-analysed separately. RESULTS 5 RCTs and 33 observational studies were included, totalling 1 085 931 women and 1 387 123 men. Meta-analyses showed that for both sexes, DOAC versus warfarin was generally associated with lower risk of stroke/SE, major bleeding and ICH; in DOAC-DOAC comparisons, rivaroxaban versus dabigatran had higher GIB risk. The only sex-specific difference observed was that when compared with warfarin, women had higher GIB risk with rivaroxaban (women: pooled risk ratio (pRR)=1.34, 95% CI=1.18 to 1.51; men: pRR=0.97, 95% CI=0.85 to 1.10; p value for interaction (p for interaction)<0.001) and possibly dabigatran (women: pRR=1.25, 95% CI=0.92 to 1.70; men: pRR=0.83, 95% CI=0.72 to 0.97; p-for-interaction=0.02). The sex difference in GIB remained for rivaroxaban when a Bonferroni-corrected significance level was used (α=0.003). No sex-specific GIB data for apixaban and edoxaban was available for the meta-analysis. CONCLUSIONS For both sexes, DOACs generally demonstrated favourable effectiveness and safety over warfarin. However, observational data suggested that women may have higher GIB risk with rivaroxaban and possibly dabigatran than warfarin. Further studies are warranted to verify our findings and elucidate sex-specific GIB risk with apixaban and edoxaban, of which the data is currently lacking.

Neurology 2024; 103:e209568. [PMID: 38857466 PMCID: PMC11226323 DOI: 10.1212/wnl.0000000000209568] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Accepted: 05/01/2024] [Indexed: 06/12/2024] Open
Abstract
BACKGROUND AND OBJECTIVES Incidence and prevalence of atrial fibrillation (AF), a risk factor of dementia, have been increasing over time. Oral anticoagulation reduces risk of stroke and other negative outcomes of AF and may reduce dementia health inequities. The objective of this study was to estimate dementia incidence in patients with newly-diagnosed AF and taking an anticoagulant as use of direct oral anticoagulants (DOACs) increased. METHODS We used a retrospective cohort design with annual incident AF cohorts of community-dwelling Medicare Fee-for-Service beneficiaries, enrolled in Parts A, B, and D from 2007 to 2017. The sample was limited to beneficiaries aged 67 years and older with incident AF; no prior dementia; and use of anticoagulants warfarin, dabigatran, rivaroxaban, apixaban, or edoxaban in year t. RESULTS A total of 1,083,338 beneficiaries were included in the study, 58.5% female, with mean (SD) age 77.2 (6.75) years. Among anticoagulated, incident AF cohorts, use of DOACs increased from 10.6% in their first year of availability (2011) to 41.4% in 2017. Among incident AF cohorts taking any oral anticoagulant, 3-year dementia incidence did not change significantly over the cohorts after adjusting for confounders. For example, incidence was 9.1% (95% CI 8.9-9.4) among White persons diagnosed with AF in 2007 and 2008 and 8.9% (95% CI 8.7-9.1) in 2017. Across cohorts, dementia incidence was consistently highest for Black persons, followed by American Indian/Alaska Native and White persons, and lowest for Asian persons. In 2017, 10.9% (95% CI 10.4-11.3) of Black persons in the cohort developed dementia within 3 years, 9.4% (95% CI 8.0-10.9) of American Indian/Alaska Native, 8.9% (95% CI 8.7-9.1) of White, 8.7% (95% CI 8.2-9.1) of Hispanic, and 6.9% (95% CI 6.4-7.4) of Asian persons. Across race/ethnicity, 3-year stroke risk decreased consistently over time; however, the increasing availability of DOACs did not alter the trend. DISCUSSION Increased use of DOACs among incident AF cohorts from 2007 to 2017 was not associated with significant declines in dementia or stroke risk. Consideration of similar stroke and dementia risk, as well as differences in cost, is warranted when weighing the risks and benefits of available oral anticoagulants.

Abstract
Annual prevalence estimates of peptic ulcer disease range between 0·12% and 1·5%. Peptic ulcer disease is usually attributable to Helicobacter pylori infection, intake of some medications (such as aspirin and non-steroidal anti-inflammatory medications), or being critically ill (stress-related), or it can be idiopathic. The clinical presentation is usually uncomplicated, with peptic ulcer disease management based on eradicating H pylori if present, the use of acid-suppressing medications-most often proton pump inhibitors (PPIs)-or addressing complications, such as with early endoscopy and high-dose PPIs for peptic ulcer bleeding. Special considerations apply to patients on antiplatelet and antithrombotic agents. H pylori treatment has evolved, with the choice of regimen dictated by local antibiotic resistance patterns. Indications for primary and secondary prophylaxis vary across societies; most suggest PPIs for patients at highest risk of developing a peptic ulcer, its complications, or its recurrence. Additional research areas include the use of potassium-competitive acid blockers and H pylori vaccination; the optimal approach for patients at risk of stress ulcer bleeding requires more robust determinations of optimal patient selection and treatment selection, if any. Appropriate continuation of PPI use outweighs most possible side-effects if given for approved indications, while de-prescribing should be trialled when a definitive indication is no longer present.

Performance of HAS-BLED and DOAC scores to predict major bleeding events in atrial fibrillation patients treated with direct oral anticoagulants: A report from a prospective European observational registry. Eur J Intern Med 2024:S0953-6205(24)00277-2. [PMID: 38969571 DOI: 10.1016/j.ejim.2024.06.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2024] [Revised: 06/17/2024] [Accepted: 06/25/2024] [Indexed: 07/07/2024]
Abstract
BACKGROUND The DOAC score has been recently proposed for bleeding risk stratification of patients with atrial fibrillation treated with direct oral anticoagulants (DOAC). OBJECTIVE To compare the performance of HAS-BLED and DOAC score in predicting major bleeding events in a contemporary cohort of European AF patients treated with DOAC. METHODS We included patients derived from a prospective observational registry of European AF patients. HAS-BLED and DOAC scores were calculated as per the original schemes. Our primary endpoint was major bleeding events. Receiver operating characteristic (ROC) curves were used to compare the predictive ability of the scores. RESULTS A total of 2834 AF patients (median age [IQR] 69 [62-77] years; 39.6 % female) treated with DOAC were included in the analysis. According to the HAS-BLED score, 577 patients (20.4 %) were categorized as very low risk of bleeding, as compared to 1276 (45.0 %) according to DOAC score. A total of 55 major bleeding events occurred with an overall incidence of 1.04 per 100 patient-years. Both scores showed only a modest ability for the prediction of bleeding events (HAS-BLED area under the curve [AUC], 0.65, 95 % confidence interval [CI] 0.55-0.70; DOAC score AUC 0.62, 95 % CI 0.59-0.71, p for difference = 0.332]. At calibration analysis, the DOAC score showed modest calibration, especially for patients at high risk, when compared to HAS-BLED. CONCLUSION In a contemporary cohort of DOAC-treated AF patients, both HAS-BLED and DOAC scores only modestly predicted the occurrence of major bleeding events. Our results do not support the preferential use of DOAC score over HAS-BLED.

Reliability of single-lead electrocardiogram interpretation to detect atrial fibrillation: insights from the SAFER feasibility study. Europace 2024; 26:euae181.

Abstract
AIMS Single-lead electrocardiograms (ECGs) can be recorded using widely available devices such as smartwatches and handheld ECG recorders. Such devices have been approved for atrial fibrillation (AF) detection. However, little evidence exists on the reliability of single-lead ECG interpretation. We aimed to assess the level of agreement on detection of AF by independent cardiologists interpreting single-lead ECGs and to identify factors influencing agreement. METHODS AND RESULTS In a population-based AF screening study, adults aged ≥65 years old recorded four single-lead ECGs per day for 1-4 weeks using a handheld ECG recorder. Electrocardiograms showing signs of possible AF were identified by a nurse, aided by an automated algorithm. These were reviewed by two independent cardiologists who assigned participant- and ECG-level diagnoses. Inter-rater reliability of AF diagnosis was calculated using linear weighted Cohen's kappa (κw). Out of 2141 participants and 162 515 ECGs, only 1843 ECGs from 185 participants were reviewed by both cardiologists. Agreement was moderate: κw = 0.48 (95% confidence interval, 0.37-0.58) at participant level and κw = 0.58 (0.53-0.62) at ECG level. At participant level, agreement was associated with the number of adequate-quality ECGs recorded, with higher agreement in participants who recorded at least 67 adequate-quality ECGs. At ECG level, agreement was associated with ECG quality and whether ECGs exhibited algorithm-identified possible AF. CONCLUSION Inter-rater reliability of AF diagnosis from single-lead ECGs was found to be moderate in older adults. Strategies to improve reliability might include participant and cardiologist training and designing AF detection programmes to obtain sufficient ECGs for reliable diagnoses.

Abstract
AIMS Atrial fibrillation (AF) and concomitant cardiometabolic disease processes interact and combine to lead to adverse events, such as stroke, heart failure, myocardial infarction, and cardiovascular death. Circulating biomolecules provide quantifiable proxies for cardiometabolic disease processes. The aim of this study was to test whether biomolecule combinations can define phenotypes in patients with AF. METHODS AND RESULTS This pre-specified analysis of the EAST-AFNET 4 biomolecule study assigned patients to clusters using polytomous variable latent-class analysis based on baseline concentrations of 13 precisely quantified biomolecules potentially reflecting ageing, cardiac fibrosis, metabolic dysfunction, oxidative stress, cardiac load, endothelial dysfunction, and inflammation. In each cluster, rates of cardiovascular death, stroke, or hospitalization for heart failure or acute coronary syndrome, the primary outcome of EAST-AFNET 4, were calculated and compared between clusters over median 5.1 years follow-up. Findings were independently validated in a prospective cohort of 748 patients with AF (BBC-AF; median follow-up 2.9 years).Unsupervised biomolecule analysis assigned 1586 patients (71 years old, 46% women) into four clusters. The highest risk cluster was dominated by elevated bone morphogenetic protein 10, insulin-like growth factor-binding protein 7, N-terminal pro-B-type natriuretic peptide, angiopoietin 2, and growth differentiation factor 15. Patients in the lowest risk cluster showed low concentrations of these biomolecules. Two intermediate-risk clusters differed by high or low concentrations of C-reactive protein, interleukin-6, and D-dimer. Patients in the highest risk cluster had a five-fold higher cardiovascular event rate than patients in the low-risk cluster. Early rhythm control was effective across clusters (Pinteraction = 0.63). Sensitivity analyses and external validation in BBC-AF replicated clusters and risk gradients. CONCLUSION Biomolecule concentrations identify cardiometabolic subphenotypes in patients with AF at high and low cardiovascular risk.

Abstract
Subclinical, device-detected atrial fibrillation (AF) is frequently recorded by pacemakers and other implanted cardiac rhythm devices. Patients with device-detected AF have an elevated risk of stroke, but a lower risk of stroke than similar patients with clinical AF captured with surface electrocardiogram. Two randomized clinical trials (NOAH-AFNET 6 and ARTESiA) have tested a direct oral anticoagulant (DOAC) against aspirin or placebo. A study-level meta-analysis of the two trials found that treatment with a DOAC resulted in a 32% reduction in ischaemic stroke and a 62% increase in major bleeding; the results of the two trials were consistent. The annualized rate of stroke in the control arms was ∼1%. Several factors point towards overall net benefit from DOAC treatment for patients with device-detected AF. Strokes in ARTESiA were frequently fatal or disabling and bleeds were rarely lethal. The higher absolute rates of major bleeding compared with ischaemic stroke while on treatment with a DOAC in the two trials are consistent with the ratio of bleeds to strokes seen in the pivotal DOAC vs. warfarin trials in patients with clinical AF. Prior research has concluded that patients place a higher emphasis on stroke prevention than on bleeding. Further research is needed to identify the characteristics that will help identify patients with device-detected AF who will receive the greatest benefit from DOAC treatment.

Pharmacist-led interventions in optimising the use of oral anticoagulants in patients with atrial fibrillation in general practice in England: a retrospective observational study. BJGP Open 2024; 8:BJGPO.2023.0113. [PMID: 38097269 PMCID: PMC11300970 DOI: 10.3399/bjgpo.2023.0113] [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: 07/10/2023] [Revised: 11/10/2023] [Accepted: 11/24/2023] [Indexed: 04/18/2024] Open
Abstract
BACKGROUND Oral anticoagulation (OAC) is the mainstay of treatment for the prevention of strokes in patients with atrial fibrillation (AF). Direct oral anticoagulants (DOACs) account for increasing OAC in patients with AF. However, prescribing DOACs for patients with established AF poses various challenges and general practice pharmacists may have an important role in supporting their management. AIM To investigate the effectiveness of pharmacist-led interventions in general practice in optimising the use of OAC therapies in AF. DESIGN & SETTING A retrospective observational study in general practices in Bradford. METHOD The data were collected retrospectively from 1 November 2018-31 December 2019 using electronic health record data. The data were analysed: 1) to identify patients with AF not on OAC; 2) to describe inappropriate DOAC prescriptions; and 3) to calculate HAS-BLED scores. RESULTS Overall, 76.3% (n = 470) of patients with AF received OAC therapy, and of these, 63.4% received DOACs. Pharmacist-led interventions increased DOAC prescribing by 6.0% (P = 0.03). Inappropriate DOAC use was identified in 24.5% of patients with AF, with underdosed and overdosed identified in 9.7% and 14.8%, respectively. Post-intervention, inappropriate prescribing was reduced to 1.7%. The mean HAS-BLED score decreased from 3.00 to 2.22 (P<0.01). Successful transition from vitamin K antagonist (VKA) therapy to DOACs was achieved in 25.7% of patients. CONCLUSION Pharmacist-led interventions have successfully improved the use of OAC therapies in patients with AF, and effectively managed the bleeding risks and transition from VKA to DOAC therapy, in line with guidelines.

Application of the Win Ratio Method in the ENGAGE AF-TIMI 48 Trial Comparing Edoxaban With Warfarin in Patients With Atrial Fibrillation. Circ Cardiovasc Qual Outcomes 2024; 17:e010561. [PMID: 38828563 DOI: 10.1161/circoutcomes.123.010561] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Accepted: 04/25/2024] [Indexed: 06/05/2024]
Abstract
BACKGROUND Cardiovascular trials often use a composite end point and a time-to-first event model. We sought to compare edoxaban versus warfarin using the win ratio, which offers data complementary to time-to-first event analysis, emphasizing the most severe clinical events. METHODS ENGAGE AF-TIMI 48 (Effective Anticoagulation With Factor Xa Next Generation in Atrial Fibrillation-Thrombolysis in Myocardial Infarction 48) was a double-blind, randomized trial in which patients with atrial fibrillation were assigned 1:1:1 to a higher dose edoxaban regimen (60/30 mg daily), a lower dose edoxaban regimen (30/15 mg daily), or warfarin. In an exploratory analysis, we analyzed the trial outcomes using an unmatched win ratio approach. The win ratio for each edoxaban regimen was the total number of edoxaban wins divided by the number of warfarin wins for the following ranked clinical outcomes: 1: death; 2: hemorrhagic stroke; 3: ischemic stroke/systemic embolic event/epidural or subdural bleeding; 4: noncerebral International Society on Thrombosis and Haemostasis major bleeding; and 5: cardiovascular hospitalization. RESULTS 21 105 patients were randomized to higher dose edoxaban regimen (N=7035), lower dose edoxaban regimen (N=7034), or warfarin (N=7046), yielding >49 million pairs for each treatment comparison. The median age was 72 years, 38% were women, and 59% had prior vitamin K antagonist use. The win ratio was 1.11 (95% CI, 1.05-1.18) for higher dose edoxaban regimen versus warfarin and 1.11 (95% CI, 1.05-1.18) for lower dose edoxaban regimen versus warfarin. The favorable impacts of edoxaban on death (34% of wins) and cardiovascular hospitalization (41% of wins) were the major contributors to the win ratio. Results consistently favored edoxaban in subgroups based on creatine clearance and dose reduction at baseline, with heightened benefit among those without prior vitamin K antagonist use. CONCLUSIONS In a win ratio analysis of the ENGAGE AF-TIMI 48 trial, both dose regimens of edoxaban were superior to warfarin for the net clinical outcome incorporating ischemic and bleeding events. As the win ratio emphasizes the most severe clinical events, this analysis supports the superiority of edoxaban over warfarin in patients with atrial fibrillation.
