Abstract
BACKGROUND D-dimer testing may help deciding the duration of anticoagulation in subjects at high risk of venous thromboembolism (VTE) recurrence. Two management studies on this issue have been published (DULCIS in 2014 and APIDULCIS in 2022). They had similar designs but had important different results. Aim of this article is to compare their results. METHODS Both studies were finalized to extend anticoagulation [with vitamin K anticoagulants (VKAs) in DULCIS or apixaban 2.5 mg BID (kindly provided by BMS-Pfizer Collaboration) in APIDULCIS] only in patients with positive D-dimer results. RESULTS More D-dimer assays resulted positive in APIDULCIS than in DULCIS (61.1 % vs 47.7 %, respectively; p < 0.0001). While only 4 (0.5 %) refused low dose apixaban in APIDULCIS, the 22.6 % of patients with positive D-dimer refused to resume VKAs in DULCIS; their rates of recurrence were 187 and 8.8 per 100 person-years, respectively (incidence rate ratio [IRR]: 21.2). The incidence of bleeding was low in those receiving apixaban vs those who resumed VKAs (0.4 vs 2.3 per 100 person-years, respectively; IRR 0.17;). While the recurrence rate was low and similar in the studies in subjects who resumed anticoagulation, it was significantly higher in APIDULCIS than in DULCIS in those who stopped anticoagulation for negative D-dimer (5.6 vs 3.0 per 100 person-years, respectively; IRR 1.9). CONCLUSION The low dose Apixaban for extended VTE treatment is effective and safe, and well accepted by patients. Why subjects who stopped anticoagulation for negative D-dimer had a higher recurrence rate in APIDULCIS than in DULCIS remains to be explained.

Abstract
Atrial fibrillation is the most frequent chronic arrhythmia in patients with chronic kidney disease. Oral anticoagulation with vitamin K antagonists and now direct oral anticoagulants have been and are the fundamental pillars for the prevention of thromboembolic events. However, there are no randomized clinical trials on the risk-benefit profile of oral anticoagulation in patients with chronic kidney disease stage 5 on peritoneal dialysis and there is little evidence in the literature in this population. The objective of our study was to know the prevalence, treatment and professionals involved in the management of atrial fibrillation in peritoneal dialysis patients. For this purpose, we performed a descriptive analysis through a survey sent to different peritoneal dialysis units in Spain. A total of 1,403 patients on peritoneal dialysis were included in the study, of whom 186 (13.2%) had non-valvular atrial fibrillation. In addition, the assessment of the scores of thromboembolic and bleeding risks for the indication of oral anticoagulation was mainly carried out by the cardiologist (60% of the units), as well as its prescription (cardiologist 47% or in consensus with the nephrologist 43%). In summary, patients on peritoneal dialysis have a remarkable prevalence of non-valvular atrial fibrillation. Patients frequently receive oral anticoagulation with vitamin K antagonists, as well as direct oral anticoagulants. The data obtained regarding the scores used for the assessment of thromboembolic and bleeding risk, treatment and involvement by Nephrology indicates that there is a need for training and involvement of the nephrologist in this pathology.

Abstract
Vitamin K antagonists (VKA) is the primary anticoagulant in most settings of Sub-Saharan Africa. Understanding the quality of anticoagulation services in the continent is vital in optimising the intended benefits. This study assessed the quality of anticoagulation and associated factors among VKA-treated patients in nine SSA countries. We conducted a retrospective cohort study of randomly selected patients on anticoagulation from 20 clinics in Botswana, the Democratic Republic of Congo, Ethiopia, Gambia, Ghana, Mozambique, Nigeria, Tanzania, and South Africa. Eligible participants were those on VKAs for at least three months and with at least four international normalised ratios (INR) results in 2019-2021. We report the proportion of INR values in the therapeutic range, time-in-therapeutic range (TTR) using the Rosendaal method, and the proportion of patients with TTR ≥ 65% (optimal anticoagulation). The mean age was 51.1(16.1) years, and 64.2% were women. The most common indications for VKA included venous thromboembolism (29.6%), prosthetic valves (26.7%) and atrial fibrillation/flutter (30.1%). We analysed 6743 INR tests from 1011 participants, and of these, 48.5% were sub-therapeutic, 34.1% therapeutic, and 17.4% were supratherapeutic relative to disease-specific reference ranges. TTR was calculated for 660 patients using 4927 INR measurements. The median (interquartile range [IQR]) TTR was 35.8(15.9,57.2) %. Optimal anticoagulation control was evident in 19.2% of participants, varying from 2.7% in Tanzania to 23.1% in Ethiopia. The proportion of patients with TTR ≥ 65% was 15,4% for prosthetic heart valves, 21.1% for venous thromboembolism and 23.7% for atrial fibrillation or flutter. Countries with universal health coverage had higher odds of optimal anticoagulation control (adjusted odds ratio (aOR) 1.79, 95% confidence interval [CI], 1.15- 2.81, p = 0.01). Patients on VKAs for different therapeutic indications in SSA had suboptimal TTR. Universal health coverage increased the odds of achieving TTR by 79%. The evidence calls for more intensive warfarin management strategies in SSA, including providing VKA services without out-of-pocket payments.

Abstract
Oral anticoagulation is the key to reduce the risk of stroke in atrial fibrillation. Although vitaminK antagonists (VKA) have classically been used for this purpose, they have been largely overcome by direct oral anticoagulants (DOAC), as demonstrated by evidence from clinical trials, real-life and population studies. In fact, all clinical practice guidelines recommend their use preferentially over VKA. However, in Spain the prescription of DOAC is subordinated to an inspection visa that includes the clinical conditions defined in the Therapeutic Positioning Report of the Spanish Medicines Agency, and that still imposes important restrictions on their use, limiting the benefits of using DOACs in patients with atrial fibrillation (AF), and also generating inequalities between the different autonomous communities. In fact, the use of DOAC in Spain is much lower than that observed in neighboring countries. This has made that while in other countries the incidence of ischemic stroke has decreased at the population level, along with a reduction in the cost per patient with AF, in Spain this decrease has been modest. For all these reasons, and for assuring the sustainability of the health care system, we ask for the elimination of the visa so that DOAC can be prescribed according to the recommendations made by the guidelines. In addition, we are also committed to reinforce medical education and decisions made by consensus with the patient, with the primary care physician acquiring a key role in the protection of the patient with AF.

Abstract
Oral anticoagulants are widely used to treat or prevent cardiovascular diseases in millions of patients worldwide. They are the drugs of choice for stroke prevention and systemic embolism in patients with non-valvular atrial fibrillation and prosthetic heart valves, as well as for treatment/prevention of venous thromboembolism. Oral anticoagulants include vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs). The hemostasis laboratory plays a crucial role in the management of treated patients, spanning from dose adjustment based on laboratory testing that applies to VKAs to the measurement of drug concentrations in special situations that apply to DOACs. This article aims to overview how the hemostasis laboratory can help clinicians manage patients on oral anticoagulants. Special interest is devoted to the international normalized ratio, used to manage patients on VKAs and to the measurement of DOAC concentrations, for which the role of the laboratory is still not very well defined, and most interferences of DOACs with some of the most common hemostatic parameters are not widely appreciated.

Abstract
BACKGROUND In patients with atrial fibrillation (AF) and normal or slightly impaired renal function, the use of direct oral anticoagulants (DOACs) is preferable to vitamin K antagonists (VKAs). However, in patients undergoing hemodialysis, the efficacy, and safety of DOACs compared with VKAs are still unknown. PURPOSE To review current evidence about the safety and efficacy of DOACs compared to VKAs, in patients with AF and chronic kidney disease under hemodialysis. METHODS We systematically searched PubMed, Scopus, and Cochrane databases for RCTs comparing DOACs with VKAs for anticoagulation in patients with AF on dialysis therapy. Outcomes of interest were: (1) stroke; (2) major bleeding; (3) cardiovascular mortality; and (4) all-cause mortality. Statistical analysis was performed using RevMan 5.1.7 and heterogeneity was assessed by I2 statistics. RESULTS Three randomized controlled trials were included, comprising a total of 383 patients. Of these, 218 received DOACs (130 received apixaban; 88 received rivaroxaban), and 165 were treated with VKAs (116 received warfarin; 49 received phenprocoumon). The incidence of stroke was significantly lower in patients treated with DOACs (4.7%) compared with those using VKAs (9.5%) (RR 0.42; 95% CI 0.18-0.97; p = 0.04; I2 = 0%). However, the difference was not statistically significant in the case of ischemic stroke specifically (RR 0.42; 95% CI 0.17-1.04; p = 0.06; I2 = 0%). As for the major bleeding outcome, the DOAC group (11%) had fewer events than the VKA group (13.9%) but without statistical significance (RR 0.75; 95% CI 0.45-1.28; p = 0.29; I2 = 0%). There was no significant difference between groups regarding cardiovascular mortality (RR 1.23; 95% CI 0.66-2.29; p = 0.52; I2 = 13%) and all-cause mortality (RR 0.98; 95% CI 0.77-1.24; p = 0.84; I2 = 16%). CONCLUSION This meta-analysis suggests that in patients with AF on dialysis, the use of DOACs was associated with a significant reduction in stroke, and a numerical trend of less incidence of major bleeding compared with VKAs, but in this case with no statistical significance. Results may be limited by a small sample size or insufficient statistical power.

Abstract
BACKGROUND AND AIM Atrial fibrillation (AF) is associated with increased risk of dementia. Whether direct oral anticoagulation (DOAC) reduce this risk compared to vitamin-K antagonist (VKA) is unclear. The aim of this study was to assess the risk of new all-cause dementia and vascular dementia in AF patients, treated with either DOAC or VKAs. METHODS Anonymized electronic medical records from the TriNetX federated research network were used. AF patients treated with DOACs within 1 month of AF diagnosis, were 1:1 propensity score-matched with those treated with a VKA. The analysis included patients who completed 5 and 10 years of follow-up and were assessed for all-cause dementia and vascular dementia. Cox proportional hazard models were used to hazard ratios (HR), respectively with 95% confidence intervals (CIs). RESULTS Among patients who completed 5 years of follow-up, after propensity score matching the final cohort consisted of 215,404 well-matched AF patients. All-cause dementia was diagnosed in 4,153 (3.9%) patients among those treated with DOACs and 4,150 (3.9%) among the VKA-treated patients (HR: 1.01, 95%CI: 0.96-1.05). Among patients 65-74 years old who were followed, DOAC treatment was associated with lower risk of dementia compared to VKAs (HR: 0.72; 95%CI: 0.59-0.86). Among patients who completed 10 years of follow-up, after propensity score matching the final cohort consisted of 19,208 well-matched AF patients. All-cause dementia was diagnosed in 314 (3.3%) patients among those treated with DOACs and 451 (4.7%) among the VKA-treated patients. DOAC treatment was associated with significantly lower risk of all-cause dementia during a follow-up period of 10 years compared to VKA treatment (HR: 0.72, 95%CI: 0.62-0.83), which remained consistent in patiens ≥65 years old. CONCLUSION This propensity-score matched analysis showed that among AF patients, treatment with a DOACs for a period of 10 years was associated with lower risk of all-cause dementia and vascular dementia compared to VKA treatment, an effect which was not apparent in those treated for shorter duration. This finding requires confirmation in ongoing randomised controlled trials.

Abstract
INTRODUCTION In a large nationwide administrative database including ∼35 % of Italian population, we analyzed the impact of oral anticoagulant treatment (OAT) in patients with a hospital diagnosis of non-valvular atrial fibrillation (NVAF). METHODS AND RESULTS Of 170404 OAT-naïve patients (mean age 78.7 years; 49.4 % women), only 61.1 % were prescribed direct oral anticoagulants, DOACs, or vitamin-K antagonists, VKAs; 14.2 % were given aspirin (ASA), and 24.8 % no anti-thrombotic drugs (No Tx). We compared ischemic stroke (IS), IS and systemic embolism (IS/SE), intracranial hemorrhage (ICH), major bleeding (MB), major gastro-intestinal bleeding, all-cause deaths and the composite outcome, across four propensity-score matched treatment cohorts with >15400 patients each. Over 2.9±1.5 years, the incidence of IS and IS/SE was slightly less with VKAs than with DOACs (1.62 and 1.84 vs 1.81 and 1.99 events.100 person-years; HR=0.85, 95%CI=0.76-0.95 and HR=0.87, 95%CI=0.78-0.97). This difference disappeared in a sensitivity analysis which excluded those patients treated with low-dose of apixaban, edoxaban, or rivaroxaban (41.7% of DOACs cohort). Compared with DOACs, VKAs were associated with greater incidence of ICH (1.09 vs 0.81; HR=1.38, 95%CI=1.17-1.62), MB (3.78 vs 3.31; HR=1.14, 95%CI=1.02-1.28), all-cause mortality (9.66 vs 10.10; HR=1.07, 95%CI=1.02-1.11), and composite outcome (13.72 vs 13.32; HR=1.04, 95%CI=1.01-1.08). IS, IS/SE, and mortality were more frequent with ASA or No Tx than with VKAs or DOACs (p<0.001 for all comparisons). CONCLUSIONS Beyond confirming the association with a better net clinical benefit of DOACs over VKAs, our findings substantiate the large proportion of NVAF patients still inappropriately anticoagulated, thereby reinforcing the need for educational programs.

Abstract
Atrial fibrillation (AF) is the most common arrhythmia in adults. Prevention of the ischaemic risk with oral anticoagulants (OACs) is widely recommended, and current clinical guidelines recommend direct oral anticoagulants (DOACs) as preference therapy for stroke prevention. However, there are currently no clinical practice guidelines or recommendation documents on the optimal management of OACs in patients with AF that specifically address and adapt to the Central American and Caribbean context. The aim of this Delphi-like study is to respond to doubts that may arise in the management of OACs in patients with non-valvular AF in this geographical area. A consensus project was performed on the basis of a systematic review of the literature, a recommended ADOLOPMENT-like approach, and the application of a two-round Delphi survey. In the first round, 31 recommendations were evaluated and 30 reached consensus, of which, 10 unanimously agreed. The study assessed expert opinions in a wide variety of contextualized recommendations for the optimal management of DOACs in patients with non-valvular atrial fibrillation (NVAF). There is a broad consensus on the clinical practice guideline (CPG) statements used related to anticoagulation indication, patient follow-up, anticoagulation therapy complications, COVID-19 management and prevention, and cardiac interventions.

Abstract
BACKGROUND The benefit-risk profile of direct oral anticoagulants (DOAC) therapy in patients with hypertrophic cardiomyopathy (HCM) and atrial fibrillation (AF) has not been well established yet. This study aimed to evaluate the efficacy and safety of DOAC compared with vitamin K antagonists (VKA) in patients with HCM and AF. METHODS PubMed, EMBASE, the Cochrane Library, and clinicaltrials.gov were searched to identify studies comparing DOAC with VKA in patients with HCM and AF. The primary endpoint was thromboembolic events. The relative risks and standard errors were pooled by random-effect models using the generic inverse variance method. RESULTS Seven observational studies involving 9395 patients were included in this meta-analysis. Compared to the VKA group, the DOAC group displayed a similar risk of thromboembolic events [RR (95%CI): 0.93 (0.73-1.20), p = 0.59] and ischemic stroke [RR (95%CI): 0.65 (0.33-1.28), p = 0.22]. The incidence of major bleeding was comparable between the two groups [RR (95%CI): 0.75 (0.49-1.15), p = 0.19]. Meanwhile, DOAC therapy was superior to VKA therapy in reducing the incidences of all-cause death [RR (95%CI): 0.44 (0.35-0.55), p < 0.001], cardiovascular death [RR (95%CI): 0.41 (0.22-0.75), p = 0.004], and intracranial hemorrhage [RR (95%CI): 0.42 (0.24-0.74), p = 0.003]. CONCLUSION In patients with HCM and AF, DOAC therapy was similar to VKA therapy in reducing the risk of thromboembolic events, without increasing bleeding risk. In addition, the DOAC group displayed significant advantages in reducing mortality and intracranial hemorrhage compared with the VKA group. Further randomized controlled trials are needed to provide more evidence for DOAC therapy in this population.

Abstract
BACKGROUND The prevalence of atrial fibrillation (AF) in individuals with end-stage renal disease (ESRD) on chronic hemodialysis is increasing. The optimal anticoagulant choice in this population is unclear since these patients were excluded from the pivotal randomized controlled trials (RCTs) of direct oral anticoagulants (DOACs) vs. vitamin K antagonists (VKAs) in the general AF population. We aimed to assess the efficacy and safety of DOACs vs. VKAs in patients with AF and ESRD on chronic hemodialysis through a systematic review and meta-analysis of all available evidence. PATIENTS/METHODS We performed a systematic search in MEDLINE and Scopus for RCTs or observational studies of patients with AF and ESRD on chronic hemodialysis who were treated with DOACs or VKAs. The outcomes of interest included ischemic stroke, the composite of ischemic stroke or systemic embolism, major bleeding, gastrointestinal bleeding, minor bleeding events and all-cause mortality. RESULTS Among 397 studies identified from the literature search, six studies (three RCTs and three observational studies) were included in the meta-analysis. Compared with VKA-treated patients, those treated with DOACs had similar risk of ischemic stroke (RR:0.76, 95% CI:0.41-1.41), ischemic stroke or systemic embolism (RR:0.65, 95% CI:0.38-1.10), major bleeding (RR:0.79, 95% CI:0.49-1.28) and all-cause death (RR:0.79, 95% CI:0.56-1.12). The risk of gastrointestinal bleeding was lower in DOAC- vs VKA-treated patients in three eligible observational studies (RR:0.73, 95% CI: 0.54-0.99, I2 = 79%) but this was not confirmed in two eligible RCTs (RR:0.69, 95% CI: 0.33-1.43, I2 = 0%). CONCLUSIONS Among AF patients with ESRD on chronic hemodialysis, the risk of ischemic stroke, ischemic stroke or systemic embolism, minor bleeding, major bleeding, and all-cause mortality is similar in patients treated with DOACs compared to VKAs. Given that the meta-analysis of RCTs on gastrointestinal bleeding did not confirm the results of the meta-analysis of the observational studies, it cannot be concluded that gastrointestinal bleeding is lower among DOAC-treated patients.

Abstract
Background and aim Current observational studies have compared the effectiveness and safety of edoxaban with other oral anticoagulants in patients with AF, but the results are still disputed. This meta-analysis was conducted to compare the effect of edoxaban in patients with AF. Methods We performed systematic research from the PubMed, EMBASE, and Cochrane Library databases until November 2022 to obtain relevant observational studies. Adjusted risk ratios (RRs) and 95 % confidence intervals (CIs) of the outcomes were collected and pooled by a random-effects model. This study was prospectively registered in PROSPERO (CRD42022314222). Results A total of 17 observational studies were included in this meta-analysis. Compared with vitamin K antagonists, edoxaban was associated with lower risks of stroke or systemic embolism (RR = 0.67, 95 % CI:0.61-0.74), major bleeding (RR = 0.54, 95 % CI:0.44-0.67), and intracranial hemorrhage (RR = 0.51, 95 % CI:0.29-0.90). Compared with dabigatran or rivaroxaban, edoxaban was associated with reduced risks of stroke or systemic embolism (dabigatran [RR = 0.76, 95 % CI:0.66-0.87]; rivaroxaban [RR = 0.81, 95 % CI:0.70-0.94]) and major bleeding (dabigatran [RR = 0.82, 95 % CI:0.69-0.98]; rivaroxaban [RR = 0.81, 95 % CI:0.70-0.94]). Compared with apixaban, edoxaban was associated with a reduced risk of stroke or systemic embolism (RR = 0.87, 95 % CI:0.79-0.97), but had similar risks of bleeding events. Conclusions Our current evidence suggested that edoxaban might have superior effectiveness and/or safety outcomes than vitamin K antagonists, dabigatran, rivaroxaban, and apixaban for stroke prevention in patients with AF.

Abstract
INTRODUCTION Life-long anticoagulation is the recommended management for chronic thromboembolic pulmonary hypertension (CTEPH). Evidence regarding the use of direct oral anticoagulants (DOAC) for CTEPH is yet to be established. We performed a systematic review and meta-analysis to clarify the outcomes of CTEPH in patients who used DOAC or vitamin K antagonists (VKA). METHODS We reviewed literature in PubMed and EMBASE through March 2023. We included studies involving patients with CTEPH where DOAC and VKA were compared. We collected data including intervention history for CTEPH, bleeding events, recurrence of VTE (venous thromboembolism), and mortality. We performed a meta-analysis using the Mantel-Haenszel method with a fixed-effects model. RESULTS We included one randomized clinical trial and six observational studies, with a total of 2969 patients. Six studies investigated major bleeding outcomes, and seven investigated all bleeding outcomes. There were no differences in major bleeding (RR 0.59, 95 % CI [0.34-1.02], I2 = 0 %) and all-bleeding (RR 0.87, 95 % CI [0.67-1.13], I2 = 0 %). Based on the five studies we included, DOAC was associated with a lower risk of mortality (RR 0.54, 95 % CI: 0.37-0.79, I2 = 5 %). However, a higher risk of recurrent pulmonary embolism (PE) was seen in three studies (RR 3.80, 95 % CI: [1.93-7.50], I2 = 11 %). No significant differences were noted in terms of VTE. CONCLUSION DOAC compared to VKA was associated with a significantly lower mortality and higher risk of recurrent PE. Since most of the included studies are observational, we must consider the existence of multiple biases and confounding factors.

Abstract
Vitamin K antagonists (VKAs) anticoagulants have been used since the 1950s as medicines and rodenticides. These molecules are mainly 4-hydroxycoumarin derivatives and act by inhibiting the vitamin K epoxide reductase (VKORC1), an endoplasmic reticulum membrane resident enzyme. However, many VKORC1 mutations have been reported over the last decade, inducing VKAs resistances and thus treatments failures. Although studies have reported experimental and computational investigations of VKAs based on VKORC1 structural homology models, the development of new effective anticoagulants has been quite complex due to the lack of structural data and reliable structure-activity relationships. However, the recent publication of VKORC1 crystal structure provides new information for further studies. Based on these findings, we combined chemical synthesis, enzymatic assays and molecular modelling methods to design a structure-activity relationship (SAR) model. Our results proved that the lipophilicity, the membrane permeability of inhibitors and their affinity towards human VKORC1 enzyme are the main characteristics for potent anticoagulants. Our SAR model managed to rank compounds according to their ability to inhibit the human VKORC1. Such a tool might constitute an alternative to evaluate new molecules potency before their chemical synthesis and biological assessment and might assist the development of new VKAs.

Abstract
The optimal duration of anticoagulation in patients with left ventricular thrombus (LVT) is unknown. The data package herein presented contains the information used to assess the effect of duration of anticoagulation in the incidence of stroke in patients with left ventricular thrombus (LVT) in a tertiary hospital. In order to collect the required data, all transthoracic echocardiography studies at our institution from January 1st 2014 to December 31st 2021 with LVT were retrieved using dedicated software (Phillips Intellispace Cardiovascular; Koninklijke Phillips N.V., 2004-2020). Second, a dataset was designed ad hoc for this study in which the recruited data for the predefined objectives were obtained from electronic medical records. These data included clinical and demographic information including treatment choices (vitamin K antagonists [VKA] versus direct oral anticoagulants [DOAC]), duration of treatment, reason for interruption of treatment, occurrence of stroke, acute myocardial infarction, bleeding events, thrombus resolution, recurrence, and death. Retrieved data were stored in an excel sheet for analysis using the statistical package STATA (StataCorp v. 15.0, College station, TX). This methodology allows the reuse of these data for further analysis, in the context of the present study and also for future recruitment of additional patients from other institutions to increase statistical power.

Abstract
INTRODUCTION AND OBJECTIVES Direct oral anticoagulant (DOAC) therapy has been shown to be safe and effective in patients with atrial fibrillation (AF). However, outcomes in AF patients with bioprosthetic valves are unclear, as this population has been underrepresented in clinical trials. The aim of this study was to assess the safety and efficacy of DOACs in this population based on the existing published literature. METHODS A systematic search and review were conducted to identify randomized clinical trials and comparative observational studies published from 2017 to January 2022 that compared DOACs and vitamin K antagonists (VKAs) in AF patients with bioprosthetic valves. Hazard ratios (HR) were collected to compare the 2 treatments in terms of cardiovascular and all-cause mortality, stroke/systemic embolism, and major bleeding. A meta-analysis combining the results was performed. RESULTS We included 12 studies (30 283 patients). DOACs and VKAs were compared based on HRs at the 95% confidence interval. DOAC therapy was associated with a significant 9% reduction in all-cause mortality (HR, 0.91; 95%CI, 0.85-0.97; P=.0068; I2=8%), with no significant differences in the risk of stroke/systemic embolism (HR, 0.87; 95%CI, 0.67-1.14; P=.29; I2=45%) or major bleeding (HR, 0.82; 95%CI, 0.67-1.00; P=.054; I2=48.7%). CONCLUSIONS DOAC therapy in AF patients with bioprosthetic valves may be associated with a significant reduction in all-cause mortality, with no reduction in the efficacy of stroke/systemic embolism prevention or increase in major bleeding risk.

Abstract
BACKGROUND AND AIMS Vitamin K antagonists (VKAs) are the first-line anticoagulants used in end stage renal disease. This population experiences a significant variability in their International Normalized Ratio (INR) over time. There is a need for methods allowing the study of the pharmacokinetics of free and total concentrations of VKAs to explain INR variability. MATERIALS AND METHODS We developed and validated a high-performance liquid chromatography-tandem mass spectrometry method allowing the quantification of warfarin and fluindione free and total plasma concentrations. Chromatographic separation was achieved in a raptor biphenyl column and the spectrometry acquisition was set in multiple reaction monitoring mode after negative electrospray ionization. We then applied it in describing the plasma free and total concentrations of VKAs in samples from 50 hemodialysis patients. RESULTS The developed method is rapid, sensitive and specific. Our cohort results showed a correlation between free and total VKA concentrations. The free VKA concentrations tended to be higher in patients with higher INR. Although VKAs are highly albumin-bound drugs, albumin concentration did not totally explain the high inter-individual total VKA concentrations variability. CONCLUSION This opens the door to further studies to understand the factors involved in their variability.

Abstract
BACKGROUND The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is a worldwide non-interventional study of stroke prevention in patients with non-valvular AF. METHODS AND RESULTS 52,080 patients with newly diagnosed AF were prospectively enrolled from 2010 to 2016. 4121 (7.9%) of these patients were recruited in DACH [Germany (n = 3567), Austria (n = 465) and Switzerland (n = 89) combined], and 47,959 patients were from 32 countries in other regions worldwide (ORW). Hypertension was most prevalent in DACH and ORW (85.3% and 75.6%, respectively). Diabetes, hypercholesterolaemia, carotid occlusive disease and vascular disease were more prevalent in DACH patients vs ORW (27.6%, 49.4%, 5.8% and 29.0% vs 21.7%, 40.9%, 2.8% and 24.5%). The use of non-vitamin K antagonist oral anticoagulants (NOACs) increased more in DACH over time. Management of vitamin K antagonists was suboptimal in DACH and ORW (time in therapeutic range of INR ≥ 65% in 44.6% and 44.4% of patients or ≥ 70% in 36.9% and 36.0% of patients, respectively). Adjusted rates of cardiovascular mortality and MI/ACS were higher in DACH while non-haemorrhagic stroke/systemic embolism was lower after 2-year follow-up. CONCLUSIONS Similarities and dissimilarities in AF management and clinical outcomes are seen in DACH and ORW. The increased use of NOAC was associated with a mismatch of risk-adapted anticoagulation (over-and-undertreatment) in DACH. Suboptimal control of INR requires educational activities in both regional groups. Higher rates of cardiovascular death in DACH may reflect the higher risk profile of these patients and lower rates of non-haemorrhagic stroke could be associated with increased NOAC use.

Abstract
OBJECTIVES Oral anticoagulation (OAC) may have an impact on mortality in cases hospitalized for hip fracture (HF). We studied nationwide time trends of OAC prescriptions and compared time trends of inhospital mortality of HF cases with and without OAC in Germany DESIGN: Retrospective cohort study SETTING: Nationwide German hospitalization, Diagnosis-Related Groups Statistic PATIENTS/PARTICIPANTS: All hospital admissions for HF 60 years and older in the years 2006 through 2020. INTERVENTION Additional diagnosis with a personal history of long-term use of anticoagulants (ICD code Z92.1). MAIN OUTCOME MEASUREMENTS Inhospital mortality RESULTS: Cases hospitalized for HF 60 years and older increased by 29.5%. In 2006, 5.6% had a documented history of long-term use of OACs. This proportion rose to 20.1% in 2020. Age-standardized hospitalization mortality in HF cases without long-term use of OACs in males decreased steadily from 8.6% (95% confidence intervals 8.2 - 8.9) in 2006 to 6.6% (6.3 - 6.9) in 2020 and in females from 5.2% (5.0 - 5.3) to 3.9% (3.7 - 4.0). Mortality of HF cases with long-term use of OACs remained unchanged: males 7.0% (5.7 - 8.2) in 2006 and 7.3% (6.7 - 7.8) in 2020, females 4.8% (4.1 - 5.4) and 5.0% (4.7 - 5.3). CONCLUSION Inhospital mortality of HF cases with and without long-term OAC show different trends. In HF cases without OAC, mortality decreased from 2006 to 2020. In cases with OAC such a decrease could not be observed.

Abstract
BACKGROUND The efficacy and safety of direct oral anticoagulants (DOACs) versus vitamin K antagonists (VKAs) for the treatment of patients with left-sided bioprosthetic heart valves (BHV) and atrial fibrillation (AF) remain controversial. This study aims to perform a meta-analysis to evaluate the efficacy and safety of DOACs versus VKAs in this region. METHODS We retrieved all relevant randomized controlled studies and observational cohort studies, which critically assessed the efficacy and safety of DOACs versus VKAs among patients with left-sided BHV and AF in databases of PubMed, Cochrane, ISI Web of Sciences, and Embase. The efficacy outcomes of this meta-analysis were stroke events and all-cause death when the safety outcomes included major and any bleeding. RESULTS The analysis integrated 13 studies while enrolling 27,793 patients with AF and left-sided BHV. DOACs reduced the rate of stroke by 33% compared with VKAs (risk ratio [RR] 0.67; 95% CI 0.50-0.91), with no increased incidence of all-cause death (RR 0.96; 95% CI 0.82-1.12). For safety outcomes, major bleeding was reduced by 28% using DOACs rather than VKAs (RR 0.72; 95% CI 0.52-0.99), while there was no difference in the events of any bleeding (RR 0.84; 95% CI 0.68-1.03). In addition, in patients younger than 75 years old, the stroke rate was reduced by 45% in the population using DOACs (RR 0.55; 95% CI 0.37-0.84). CONCLUSION Our meta-analysis demonstrated that in patients with AF and BHV, compared with VKAs, using DOACs was associated with reduced stroke and major bleeding events without an increase of all-cause mortality and any bleeding. In the population younger than 75 years old, DOAC might be more effective in preventing cardiogenic stroke.

Abstract
To compare the efficacy/effectiveness and safety of DOACs versus VKAs in patients with a previously and newly surgically implanted BHV with or without AF. A systematic search on MEDLINE and EMBASE was performed till November 2022. Treatment effects were estimated with relative risk (RR) and 95% confidence intervals (CIs). Statistical heterogeneity was assessed with the I2 statistic. Four randomized controlled trials (RCTs), 2 subgroup analysis from ARISTOTLE and ENGAGE-AF-TIMI 48 and 4 observational studies were included for a total of 5808 patients, 1893 on DOACs and 3915 on VKAs. AF prevalence was 98.28%. In the overall analysis, DOACs vs VKAs were associated with a RR for stroke/transient ischemic attack (TIA)/systemic embolism (SE) of 0.63 (95% CI 0.51-0.79; I2 = 0%) and a RR of major bleeding of 0.50 (95% CI 0.39-0.63; I2 = 0%) in a median follow-up of 19 months (IQR 4.5-33.4). In the 3 RCTs (DAWA, RIVER, ENAVLE), DOACs vs VKAs were associated with a RR of stroke/TIA/SE and major bleeding of 0.38 (95% CI 0.13-1.58, I2 = 0%) and of 0.68 (95% CI 0.32-1.44; I2 = 5%) respectively. In patients randomized during the first three months from valve surgery, DOACs vs VKAs were associated with a RR of stroke/TIA/SE and major bleeding of 0.54 (95% CI 0.14-2.08; I2 = 0%) and of 0.76 (95% CI 0.05-10.72; I2 = 66%). In previously implanted BHV patients with AF, DOACs showed a risk-benefit profile at least comparable to VKAs. DOACs showed a similar, even if underpowered, risk-benefit profile during the first three months after BHV implantation prevalently in patients with AF.

Abstract
Introduction Treatment with cannabis extracts for a variety of diseases has gained popularity. However, differences in herb-drug interaction potential of extracts from different plant sources are poorly understood. In this study, we provide a characterization of cannabis extracts prepared from four cannabis chemotypes and an in vitro assessment of their Cytochrome P450 (CYP)-mediated herb-drug interaction profiles. Methods Plant extracts were either commercially obtained or prepared using ethanol as solvent, followed by overnight decarboxylation in a reflux condenser system. The extracts were characterized for their cannabinoid content using NMR and HPLC-PDA-ELSD-ESIMS. CYP inhibition studies with the cannabis extracts and pure cannabinoids (tetrahydrocannabinol [THC] and cannabidiol [CBD]) were performed using pooled, mixed gender human liver microsomes. Tolbutamide and testosterone were used as specific substrates to assess the inhibitory potential of the extracts on CYP2C9 and CYP3A4, and the coumarinic oral anticoagulants warfarin, phenprocoumon, and acenocoumarol were studied as model compounds since in vivo herb-drug interactions have previously been reported for this compound class. Results In accordance with the plant chemotypes, two extracts were rich in THC and CBD (at different proportions); one extract contained mostly CBD and the other mostly cannabigerol (CBG). Residual amounts of the corresponding acids were found in all extracts. The extracts with a single major cannabinoid (CBD or CBG) inhibited CYP2C9- and CYP3A4-mediated metabolism stronger than the extracts containing both major cannabinoids (THC and CBD). The inhibition of CYP3A4 and CYP2C9 by the extract containing mostly CBD was comparable to their inhibition by pure CBD. In contrast, the inhibitory potency of extracts containing both THC and CBD did not correspond to the combined inhibitory potency of pure THC and CBD. Although being structural analogs, the three coumarin derivatives displayed major differences in their herb-drug interaction profiles with the cannabis extracts and the pure cannabinoids. Conclusion Despite the fact that cannabinoids are the major components in ethanolic, decarboxylated cannabis extracts, it is difficult to foresee their herb-drug interaction profiles. Our in vitro data and the literature-based evidence on in vivo interactions indicate that cannabis extracts should be used cautiously when co-administered with drugs exhibiting a narrow therapeutic window, such as coumarinic anticoagulants, regardless of the cannabis chemotype used for extract preparation.

Abstract
A survey was carried out to assess the state of organization of care (including clinical and laboratory) delivered to patients on vitamin K antagonists (VKA) or direct oral anticoagulants (DOAC) followed by clinics affiliated with the Italian Federation of Thrombosis Centers (FCSA), traditionally engaged to assist anticoagulated outpatients within the country. Participants were asked to answer questions concerning (i) proportion of patients on VKA-vs-DOAC and (ii) whether dedicated testing for DOAC is available. The proportion of patients on VKA-vs-DOAC was 60 % vs 40 %. This proportion is in sharp contrast with the real-life distribution where DOAC outweigh VKA prescriptions. Furthermore, the proportion of anticoagulation clinics that provide DOAC testing (even in special situations) is relatively small (i.e., 31 % of the respondents). Furthermore, 25 % of those that declared to follow DOAC patients do not provide any testing at all. The answers to the above questions cause concerns as (i) most patients on DOAC within the country are probably on self-management, or they are managed by general practitioners or specialists outside thrombosis centers. (ii) Most patients on DOAC have no access to testing even in special situations where it would be needed. We feel that there is a (false) perception that the care needed for DOAC treatment can be much less than that required for VKA, as DOAC require prescription and not regular follow-up. A call for action should be urgently made to reassess the role of anticoagulation clinics, which should pay the same attention to patients on DOAC as those on VKA.

Abstract
Non-vitamin K antagonist oral anticoagulants (NOACs) have revolutionized treatment of atrial fibrillation. Although benefits of anticoagulation therapy are clear, a minority of patients still experience treatment inefficacy or harm. All NOACs have varying degree of renal clearance, which may significantly affect plasma concentrations. Pivotal clinical trials have explored the effects of dose reduction in patients with chronic renal disease. None of these have, however, specifically addressed the need for a dose up-titration in patients with renal hyperfiltration, in whom lower drug plasma levels are to be expected. A signal for lower efficacy in this patient subset has recently emerged. We systematically assessed the peer-reviewed scientific literature on this topic, including a recently reported randomized pharmacokinetic study in renal hyperfiltrators also reporting on ischemic and bleeding events. We conclude that the reduction in NOAC plasma levels in AF patients with renal hyperfiltration is limited in extent and, does not translate into a clinically meaningful reduction in efficacy for NOACs as compared to vitamin K antagonists (VKAs) in such patients. At the current state of knowledge, NOAC current dosing should not be altered in patients with high-normal renal function.

Abstract
Chronic kidney disease (CKD) is an independent risk factor for presenting atrial fibrillation (AF), which conditions an increased risk already present in CKD of suffering a thromboembolic event. And this risk is even higher in the hemodialysis (HD) population. On the other hand, in CKD patients and even more so in HD patients, the probability of suffering serious bleeding is also higher. Therefore, there is no consensus on whether or not to anticoagulate this population. Taking as a model what is advised for the general population, the most common attitude among nephrologists has been to opt for anticoagulation, even though there is no randomized studies to support it. Classically, anticoagulation has been done with vitamin K antagonists, at high cost for our patients: severe bleeding events, vascular calcification, and progression of nephropathy, among other complications. With the emergence of direct-acting anticoagulants, a hopeful outlook was opened in the field of anticoagulation, as they were postulated as more effective and safer drugs than antivitamin K. However, in clinical practice, this has not been the case. In this paper we review various aspects of AF and its anticoagulant treatment in the HD population.

Abstract
Background Vitamin K antagonists and different direct oral anticoagulants (DOACs) have different renal clearance rates. However, the impact of different stages of chronic renal impairment on the efficacy and safety of warfarin, dabigatran, rivaroxaban, apixaban, and edoxaban in atrial fibrillation (AF) patients remains unclear. Methods This study enrolled AF patients from the Chang Gung Research Database. The study endpoints included thromboembolic events, major/fatal bleeding, gastrointestinal (GI) bleeding and intracranial hemorrhage (ICH). The risks of time to study endpoints between groups were compared using a Cox proportional hazards regression model with adjustment. Results This study enrolled 3525 patients with moderate renal impairment (30 ≤ creatinine clearance (CrCl) < 60 mL/min), 2846 patients with mild renal impairment (60 ≤ CrCl < 90 mL/min) and 1153 patients with CrCl ≥ 90 mL/min. Over the 3.3 ± 0.9 years follow-up period, the cumulative thromboembolic events rates and the cumulative event rates of major/fatal bleeding and ICH did not differ among the warfarin and different DOAC groups at different stages of chronic renal impairment. The annual incidences of thromboembolic events, major/fatal bleeding, GI bleeding, and ICH were similar among the warfarin and different DOAC groups at different stages of renal impairment. Conclusion There did not appear to be major differences in bleeding or thromboembolic risk compared to warfarin in AF patients across a range of degree of renal failure when appropriate dose reductions of the DOACs are made.

Abstract
Introduction The direct oral anticoagulant (DOAC) apixaban has shown to have non-inferior efficacy and better safety than vitamin K antagonists (VKAs) in patients with venous thromboembolism (VTE). We determined whether healthcare resource use (HCRU) and direct all-cause medical and non-medical costs in patients with VTE in France differed between VKAs and apixaban. Methods A retrospective cohort study was conducted using French national health data from January 2013–June 2018 for anticoagulant-naïve adults hospitalized with VTE. All-cause costs and HCRU per patient per month (PPPM) were compared between apixaban and VKA cohorts created by 1:1 propensity score matching. Two-part models with bootstrapping were used to calculate marginal effects for costs and HCRU. Results The matched VKA and apixaban cohorts each comprised 7503 patients. Compared to VKAs, patients prescribed apixaban had significantly lower (P < 0.0001) mean all-cause costs PPPM for outpatient visits (€438.54 vs. €455.58), overall laboratory tests (€21.26 vs. €83.73), and hospitalizations (€249.48 vs. €343.82), but significantly higher (P < 0.0001) mean all-cause costs PPPM for overall drugs (€97.06 vs. €69.56) and medical procedures (€42.12 vs. €35.50). Mean total all-cause direct medical costs (€687.93 vs. €798.70) and total all-cause direct medical and non-medical costs (€771.60 vs. €883.66) were significantly lower (P < 0.0001) for apixaban. Mean HCRU PPPM showed similar trends. Subgroup analyses showed that, among patients with recurrent VTE, patients prescribed apixaban had significantly lower (P < 0.0001) all-cause costs PPPM for total medical costs (€17.26 vs. €18.12) and total all-cause direct medical and non-medical costs (€18.37 vs. €19.20) than patients prescribed VKAs. Similarly, among patients with bleeding, patients prescribed apixaban had significantly lower (P < 0.0001) all-cause costs PPPM for total medical costs (€15.34 vs. €32.61) and total all-cause direct medical and non-medical costs (€16.23 vs. €34.63) than patients prescribed VKAs. Conclusion Compared to VKAs, apixaban may be cost-saving in the treatment of patients hospitalized for acute VTE.

Abstract
Hip fractures are among the most common fractures operated by orthopedic surgeons. Many elderly patients, who account for a significant percentage of hip fractures, suffer from medical conditions requiring antiplatelet and anticoagulant administration. Meanwhile, considerable evidence recommends early surgery within 48b hours of admission. We aim to review the existing evidence regarding the perioperative management of antiplatelet and anticoagulant drugs in hip fractures. It was concluded that surgery for hip fractures in patients with antiplatelet drug consumption should not be delayed unless a clear contraindication exists. Active reversal strategies are indicated for patients with hip fractures and warfarin therapy. However, evidence for the safety of these agents in pregnancy, breastfeeding state, and adolescence has not yet been established. Little data exists about perioperative management of direct-acting oral anticoagulants in hip fractures. Early surgery after 12-24 hours of drug cessation has been suggested in studies; however, it should be employed cautiously. Despite extensive research, the importance of the issue necessitates additional higher-quality studies.

Abstract
Vitamin K antagonists (VKA) are recommended in patients with mechanical heart valves. Major bleeding events remain the most life-threatening complication of this therapy and sometimes it can occur in unusual anatomic areas. Spontaneous retroperitoneal hematoma is one of the rare complications of anticoagulation therapy, which needs to be recognized early and managed promptly. Here, we report a case of a 40-year-old woman with mechanical heart valve treated with acenocoumarol, who was admitted to the emergency department with abdominal pain and whose investigations came back in favor of a massive retroperitoneal hematoma. The patient was successfully treated through conservative management resulting in a good outcome. Clinicians should be careful when prescribing VKA and should always think of retroperitoneal bleeding in the event of abdominal pain or a sudden decrease in the hemoglobin levels of anticoagulated patients.

Abstract
Oral vitamin K antagonists (VKAs), warfarin, have been in routine clinical use for almost 70 years for various cardiovascular conditions. Direct-Acting Oral Anticoagulants (DOACs) have emerged as competitive alternatives for VKAs to prevent stroke in patients with non-valvular atrial fibrillation (AF) and have become the preferred choice in several clinical indications for anticoagulation. Recent guidelines have limited the use of DOACs to patients with non-valvular AF to reduce the risk of cardioembolic complications and to treat venous thromboembolism (VTE). Although emerging evidence is suggestive of its high efficacy, there was a lack of data to support DOACs safety profile in patients with mechanical valve prosthesis, intracardiac thrombi, or other conditions such as cardiac device implantation or catheter ablation. Therefore, several clinical trials have been conducted to assess the beneficial effects of using DOACs, instead of VKAs, for various non-guideline-approved indications. This review aimed to discuss the current guideline-approved indications for DOACs, advantages, and limitations of DOACs use in various clinical indications highlighting the potential emerging indications and remaining challenges for DOACs use. Several considerations are in favour of switching from warfarin to DOACs including superior efficacy, better adverse effect profile, fewer drug-drug interactions, and they do not require frequent international normalized ratio (INR) monitoring. Large randomized controlled trials are required to determine the safety and efficacy of their use in various clinical indications.

Abstract
PURPOSE The objective of present study was to compare the safety and efficacy of resuming direct-acting oral anticoagulants (DOACs) and vitamin K antagonists (VKAs) in patients with atrial fibrillation (AF) and prior gastrointestinal bleeding (GIB). METHODS PubMed, Embase, Web of Science, and the Cochrane Library were searched from their inception until 2 June 2021 for observational cohort studies in patients with AF, who resumed VKAs or DOACs after a history of GIB. Studies that reported data on clinical outcomes including risk of recurrent GIB, thromboembolic events, or all-cause mortality were included. A network meta-analysis was performed to calculate the pooled hazard ratio (HR) and associated 95% credible intervals (CIs), using a random effects model in a Bayesian framework. RESULTS A total of 10 studies were included in the final analysis, including 59,244 AF patients with prior GIB, of whom 27,793 resumed DOACs, 24,635 resumed warfarin, and 6816 did not resume anticoagulation. Compared with no resumption of anticoagulation, resumption of warfarin was associated with an increased risk of recurrent GIB (HR 1.33, 95% CI: 1.06-1.70), but no increased risk of recurrent GIB was found with resumption of DOACs (HR 1.22, 95% CI: 0.88-1.71); among individual DOACs, only rivaroxaban was associated with an increased risk of recurrent GIB (HR 1.67, 95% CI: 1.16-2.65). Compared with no resumption of anticoagulation, resumption of DOACs and warfarin was associated with a significant reduction in all-cause mortality (HR 0.57, 95% CI: 0.40-0.84; HR 0.58, 95% CI: 0.44-0.79), but no statistically significant reduction in thromboembolic events (HR 0.69, 95% CI: 0.4-1.2; HR 0.83, 95% CI: 0.55-1.29). CONCLUSIONS In AF patients with prior GIB, resumption of DOACs may be safer, except for rivaroxaban.

Abstract
Introduction Emergency physicians and trauma surgeons are increasingly confronted with pre-injury direct oral anticoagulants (DOACs). The objective of this study was to assess if pre-injury DOACs, compared to vitamin K antagonists (VKA), or no oral anticoagulants is independently associated with differences in treatment, mortality and inpatient rehabilitation requirement. Methods We performed a review of the prospectively maintained institutional trauma registry at an urban academic level 1 trauma center. We included all geriatric patients (aged ≥ 65 years) with tICH after a fall, admitted between January 2011 and December 2018. Multivariable logistic regression analysis controlling for demographics, comorbidities, vital signs, and tICH types were performed to identify the association between pre-injury anticoagulants and reversal agent use, neurosurgical interventions, inhospital mortality, 3-day mortality, and discharge to inpatient rehabilitation. Results A total of 1453 tICH patients were included (52 DOAC, 376 VKA, 1025 control). DOAC use was independently associated with lower odds of receiving specific reversal agents [odds ratio (OR) 0.28, 95% confidence interval (CI) 0.15–0.54] than VKA patients. DOAC use was independently associated with requiring neurosurgical intervention (OR 3.14, 95% CI 1.36–7.28). VKA use, but not DOAC use, was independently associated with inhospital mortality, or discharge to hospice care (OR 1.62, 95% CI 1.15–2.27) compared to controls. VKA use was independently associated with higher odds of discharge to inpatient rehabilitation (OR 1.41, 95% CI 1.06–1.87) compared to controls. Conclusion Despite the higher neurosurgical intervention rates, patients with pre-injury DOAC use were associated with comparable rates of mortality and discharge to inpatient rehabilitation as patients without anticoagulation exposure. Future research should focus on risk assessment and stratification of DOAC-exposed trauma patients.

Abstract
BACKGROUND Anticoagulation clinics faced an unprecedented challenge during the COVID-19 pandemic to safely manage patients on warfarin therapy. METHODS A London teaching hospital trust received INR point-of-care (POC) testing devices from its clinical commissioning group. The Trust distributed the devices to patients who were cognitively and physically able to self-test and evaluated clinical outcomes and patient experience. FINDINGS A significant improvement in warfarin control (mean time in therapeutic range (TTR) before POC 52%, standard deviation (SD) 24.8, vs mean after 60.7%, SD 19.7; P>0.009) and a 39% reduction in missed appointments were seen in self-testing patients. Positive patient satisfaction and lifestyle outcomes were identified through a telephone survey. A minority of patients struggled with the technique, leading to frustration. Some patients used many test strips through unsuccessful and additional tests. CONCLUSION POC testing in a carefully selected group of patients on warfarin therapy resulted in positive clinical and patient satisfaction outcomes. Appropriate governance processes are needed, and clinical expertise is required to support patients. Cost-effectiveness of POC testing needs careful monitoring.

Abstract
Objective To determine the prevalence of prescription of oral anticoagulation in patients aged > 60 years with nonvalvular atrial fibrillation (NVAF). Methods Observational, cross-sectional, retrospective study based on a review of the clinical histories of patients aged >60 years diagnosed with NVAF from July 1 to September 30, 2019 and seen at the outpatient clinic (cardiology, internal medicine, geriatrics) of a secondary-level hospital in Queretaro, Mexico. Clinical profile and oral anticoagulant treatment were analyzed. Results The study population comprised 300 patients (mean age, 77.2±8.3 years; 53.3% women; 81% attended in cardiology). Of these, 91% had a high thromboembolic risk, 22.7% a high bleeding risk, and 1.7% contraindications for anticoagulation. Comorbidity was frequent. As for therapy, 82.7% were taking direct oral anticoagulants (DOAC), 11.0% vitamin K antagonists (VKA), and 6.3% no anticoagulant treatment. Anticoagulant therapy was inappropriate in 29.3% of patients, mainly because DOAC were prescribed without adjusting for age, weight, or serum creatinine and administered without indication according to thromboembolic risk. Only 39.4% of patients taking VKA were within the therapeutic range. Of all patients receiving DOAC, 48.0% were taking rivaroxaban, mainly at 20 mg/d (73.1%). Conclusions Thromboembolic risk is high in geriatric patients with NVAF. Anticoagulation is contraindicated in <2% of patients. Oral anticoagulants are prescribed inappropriately in three out of ten patients.

Abstract
INTRODUCTION Spontaneous spinal epidural hematoma (SSEH) is a rare finding, but one with serious clinical implications. Oral anticoagulant drugs are known to be associated with the SSEH onset, particularly when combined with drugs increasing the bleeding risk. CASE PRESENTATION We present the case of a 62-year-old female on acencoumarol for her atrial fibrillation complicating severe mitral stenosis with a history of Ketoprofen use for the onset of her first symptoms. She presented to our emergency room with paraplegia and sphincter disturbance. Spinal magnetic resonance imaging (MRI) revealed a posterior SSEH extended from T10 to T12 requiring an urgent decompression of the spinal cord by laminectomy performed within 48 hours from the symptom's onset. After 3 months of rehabilitation, the patient improves partially her muscular strength with mostly unchanged sensitive and sphincteric levels. CLINICAL DISCUSSION Vitamin K antagonists (VKA) use appears to be a high suspicion index for SSEH diagnosis resulting in earlier surgery and improving neurological outcome. Also, it is important to pay attention to the concomitant use of VKA and non-steroidal anti-inflammatory drugs which increase the risk of bleeding and may worsen the neurological outcome. CONCLUSION SSEH is a rare and serious finding which should be especially searched when a history of oral anticoagulation is reported in presence of neurological symptoms. A prompt and suitable management may improve the patient outcomes.

Abstract
INTRODUCTION Vitamin K antagonists (VKA) are a therapeutic alternative in patients with venous thromboembolic disease; however, numerous factors affect their pharmacology. OBJECTIVE To evaluate the quality of VKA anticoagulation at three different time periods in Mexico. METHODS Prospective study, nested in patient cohorts at three different clinical scenarios between 2013 and 2019. Outpatients with indication for treatment with VKAs for at least 12 months were included. Patients were managed according to the criteria of the treating physician. RESULTS Patient general characteristics were similar between groups, except for the VKA indication. The results of 4,148 patients and 38,548 INR assessments were analyzed. The times in therapeutic range during the three phases of the study and pooled data were significantly higher for the anticoagulation clinic. Only the number of patient visits was significantly associated with the results, unlike age, gender, and type of VKA. CONCLUSIONS VKAs are widely used, but it is difficult for therapeutic goals to be achieved, especially in non-specialized clinical services. Creation of anticoagulation clinics is an urgent need for the Mexican health system.

Abstract
Geriatric patients often have cardiovascular diseases that require differentiated perioperative management of hemostasis. The operation-related bleeding risk and the individual thromboembolism risk mutually influence each other, so that a differentiated preoperative assessment of the further prescription of coagulation-modulating medication is required. In many cases the active coagulation medication can be interrupted without replacement or continued unchanged. In cardiovascular diseases with antiplatelet medication, the preoperative risk-benefit assessment for most operations leads to the continuation of previous platelet aggregation inhibitor monotherapy; however, if there is a high risk of cardiovascular thromboembolism with dual platelet inhibition, the individual perioperative medication should be closely coordinated with a geriatrician or cardiologist.In most cases, the intake of vitamin K antagonists (VKA) can be preoperatively interrupted. In cases of high risk of thromboembolism, a temporary bridging with heparin must be carried out. The introduction of the four new direct oral antagonists (DOAC) has made the perioperative management of anticoagulation much easier. Bridging with heparin is not necessary. Perioperatively, only the dosage and timing of interruption of the DOACs have to be determined individually depending on the operative bleeding risk as well as the age, body weight and kidney function of the patient. If bleeding complications arise under the influence of the DOACs, antidotes are available for three of the four DOACs, which in acute cases can be used in addition to prothrombin complex concentrates and fresh frozen plasma to normalize coagulation.

Abstract
Atrial fibrillation (AF) is the most common arrhythmia in chronic kidney disease (CKD), with a close bidirectional relationship between the two entities. The presence of CKD in AF increases the risk of thromboembolic events, mortality and bleeding. Vitamin K antagonists (VKA) have been the mainstay of treatment for the prevention of thromboembolic events in AF until recently, with confirmed benefits in AF patients with stage 3 CKD. However, the risk-benefit profile of VKA in patients with AF and stages 4-5 CKD is controversial due to the lack of evidence from randomized controlled trials. Treatment with VKA in CKD patients has been associated with conditions such as poorer anticoagulation quality, increased risk of bleeding, faster progression of vascular/valvular calcification and higher risk of calciphylaxis. Direct oral anticoagulants (DOACs) have shown equal or greater efficacy in stroke/systemic embolism prevention, and a better safety profile than VKA in post-hoc analysis of the pivotal randomized controlled trials in patients with non-valvular AF and stage 3 CKD, yet evidence of its risk-benefit profile in more advanced stages of CKD is scarce. Observational studies associate DOACs with a good safety/effectiveness profile compared to VKA in non-dialysis CKD patients. Further, DOACs have been associated with a lower risk of acute kidney injury and CKD development/progression than VKA. This narrative review summarizes the evidence of the efficacy and safety of warfarin and DOACs in patients with AF at different CKD stages, as well as their effects on renal function, vascular/valvular calcification and bone health.

Abstract
In the year 2021 we celebrate the 80th anniversary of the first clinical use of vitamin K antagonists (VKAs), the mainstay of prevention and long-term treatment of thromboembolic disease. The discovery and development of oral anticoagulants is one of the most important chapters in the history of medicine, a goal pursued by physicians trying to combat the clinical manifestations of thrombosis since ancient times. Until the last decade, VKAs were the only oral anticoagulants available and used in clinical practice. Today, their clinical use has progressively shrunk, as the non-vitamin K antagonist oral anticoagulants (NOACs) are increasingly replacing VKAs in various conditions after the successful completion of several large randomized controlled trials. Currently, new research is tackling upstream components of the intrinsic pathway - particularly factor XI and factor XII - for the development of new, even safer anticoagulants promising to reduce bleeding without compromising efficacy. This review highlights the evolution of oral anticoagulant therapy tracing the key stages of a long and fascinating history that has unfolded from the first part of the twentieth century until today, indeed an intriguing journey where serendipity is intertwined with the tenacious work of many researchers.

Abstract
OBJECTIVES Patients treated with oral anticoagulants need an adapted education in order to optimize the management of these treatments. The objective was to assess the knowledge of patients before and after a pharmaceutical interview carried out by pharmacy students on digital tablets at the hospital. METHODS A prospective study took place in the cardiology department, with a first phase from December 2016 to June 2018. Patient's knowledge were assessed during a pharmaceutical interview; additional informations were done for unacquired concepts. The second phase took place in October 2018, and patient's knowledge were assessed during a phone call for patients who had at least given one wrong answer on the four selected questions. RESULTS Sixty-eight and twenty-two patients were included respectively for phases 1 and 2 (mean age=70±3.4; treatments number=8.2±0.9). 36 patients were treated by Vitamin K antagonists and 32 by direct oral anticoagulants. 57% of patients with oral anticoagulants gave a good answer for principles of the treatment and the surveillance during phase 1, and 33% for signs of overdose. A significant improvement for the 22 patients with poor knowledge was observed in phase 2 (1.73 vs. 2.5; P=0.006). CONCLUSIONS The playful interview improves the patient's knowledge over time. Developing the relationship between the hospital and community pharmacists would allow us to optimize the patient follow-up.

Abstract
AIMS Adherence to guideline-directed oral anticoagulation (OAC) in patients with atrial fibrillation (AF) improves outcomes, but limited data are available from China. We evaluated the adherence to guideline-directed anticoagulation and its impact on clinical outcomes in a high-risk cohort of elderly Chinese patients. METHODS AND RESULTS The Optimal Thromboprophylaxis in Elderly Chinese Patients with Atrial Fibrillation (ChiOTEAF) registry is a prospective, multicentre study conducted from October 2014 to December 2018. Endpoints of interest were all-cause death, thromboembolic (TE) events and major bleedings in patients with a guideline-directed indication for OACs (CHA2DS2-VASc ≥1 if male or ≥2 if female). The eligible cohort consisted of 5742 patients, of whom 2567 (44.7%) patients were treated with an OAC. Seven independent predictors of OAC undertreatment were identified: age [odds ratio (OR): 1.04; 95% confidence interval (CI): 1.03-1.05; P < 0.001], first diagnosed AF (OR: 1.71; 95%CI: 1.44-2.03; P < 0.001), chronic kidney disease (OR: 1.67; 95%CI: 1.36-2.06; P < 0.001), liver disease (OR: 1.69; 95%CI: 1.19-2.41; P = 0.003), dementia (OR: 1.67; 95%CI: 1.06-2.64; P = 0.026), prior extracranial bleeding (OR: 1.89; 95%CI: 1.35-2.64; P < 0.001), and the use of antiplatelet drug (OR: 6.97; 95%CI: 5.89-8.23; P < 0.001). On multivariate analysis, OAC undertreatment was significantly associated with a higher risk all-cause death (OR: 3.79; 95%CI: 2.61-5.53; P < 0.001) and TE events (OR: 2.28; 95%CI: 1.39-3.72; P = 0.001), and a similar risk of major bleeding as compared with guideline-directed OAC therapy. CONCLUSION Only 44.7% of all eligible patients were prescribed OAC in accordance with guideline recommendations. The independent predictors for OAC undertreatment were age, first diagnosed AF, chronic kidney disease, chronic obstructive pulmonary disease, prior extracranial bleeding, and the use of the antiplatelet drugs. Guideline-adherent thromboprophylaxis was safe and may be associated with improved survival and less TE among elderly Chinese patients with AF.

Abstract
Aims Persistence with direct oral anticoagulants (DOACs) has become a concern in non-valvular atrial fibrillation (NVAF) patients, but whether this affects prognosis is rarely studied. We investigated the persistence with oral anticoagulants (OACs) and its association with prognosis among a nationwide cohort of NVAF patients. Methods and results DOAC-naive NVAF patients who started to use DOACs for ischaemic stroke prevention between 2013 and 2018 were included using Dutch national statistics. Persistence with OACs was determined based on the presence of a 100-day gap between the last prescription and the end of study period. In 93 048 patients, 75.7% had a baseline CHA2DS2-VASc score of ≥2. The cumulative incidence of persistence with OACs was 88.1% [95% confidence interval (CI) 87.9–88.3%], 82.6% (95% CI 82.3–82.9%), 77.7% (95% CI 77.3–78.1%), and 72.0% (95% CI 71.5–72.5%) at 1, 2, 3, and 4 years after receiving DOACs, respectively. Baseline characteristics associated with better persistence with OACs included female sex, age range 65–74 years, permanent atrial fibrillation, previous exposure to vitamin K antagonists, stroke history (including transient ischaemic attack), and a CHA2DS2-VASc score ≥2. Non-persistence with OACs was associated with an increased risk of the composite outcome of ischaemic stroke and ischaemic stroke-related death [adjusted hazard ratio (aHR) 1.79, 95% CI 1.49–2.15] and ischaemic stroke (aHR 1.58, 95% CI 1.29–1.93) compared with being persistent with OACs. Conclusion At least a quarter of NVAF patients were non-persistent with OACs within 4 years, which was associated with poor efficacy of ischaemic stroke prevention. The identified baseline characteristics may help identify patients at risk of non-persistence.

Abstract
Background Bleeding is the most common complication of oral anticoagulants, due to inadequate dosing. Case presentation This report describes the clinical course of a patient who developed severe bleeding under therapy with phenprocoumon, despite an INR in the lower therapeutic range. Strikingly, aPTT was prolonged, while factor IX activity was significantly reduced. Acquired hemophilia was excluded, due to missing detection of inhibitors. Finally, sequencing part of the factor IX gene including nucleotide position c.110 revealed a hemizygous factor IX mutation c.110C > T p (Ala37Val). Conclusions In rare cases, missense mutations in factor IX propeptide are associated with severe bleeding complications. The substitution of alanin at position 37 to either valin or threonin (Ala37Val or Ala37Thr) leads to hypersensitivity to vitamin k antagonists.

Abstract
Direct oral anticoagulants (DOACs) are being increasingly used in patients with chronic thromboembolic hypertension (CTEPH), however, the data on their safety and efficacy are scarce and contradictory. We systematically searched MEDLINE and Google Scholar databases from January 2010 to January 2021 for studies of DOACs in CTEPH. Three observational studies, 2 abstracts and one case series met our inclusion criteria. While these studies reported similar or even less rates of major bleeding in patients receiving DOACs compared with vitamin K antagonists, there were concerns about the possibility of increased risk of venous thromboembolism recurrence with DOAC therapy. Further studies are warranted to better define the role of DOACs in CTEPH.

Abstract
AIMS Vitamin K antagonists (VKAs) are effective drugs reducing the risk for stroke in atrial fibrillation (AF), but the benefits derived from such therapy depend on the international normalized ratio (INR) maintenance in a narrow therapeutic range. Here, we aimed to determine independent variables driving poor anticoagulation control [defined as a time in therapeutic range (TTR) <65%] in a 'real world' national cohort of AF patients. METHODS AND RESULTS The SULTAN registry is a multicentre, prospective study, involving patients with non-valvular AF from 72 cardiology units expert in AF in Spain. At inclusion, all patients naïve for oral anticoagulation were started with VKAs for the first time. For the analysis, the first month of anticoagulation and those patients with <3 INR determinations were disregarded. Patients were followed up during 1 year. A total of 870 patients (53.9% male, the mean age of 73.6 ± 9.2 years, mean CHA2DS2-VASc and HAS-BLED of 3.3 ± 1.5 and 1.4 ± 0.9, respectively) were included in the full analysis set. In overall, 7889 INR determinations were available. At 1-year, the mean TTR was 63.1 ± 22.1% and 49.2% patients had a TTR < 65%. Multivariate Cox regression analysis showed that coronary artery disease [odds ratio (OR) 1.81, 95% confidence interval (CI) 1.14-2.87; P = 0.012] and amiodarone use (OR 1.54, 95% CI 1.01-2.34; P = 0.046) were independently associated with poor quality of anticoagulation (TTR <65%). CONCLUSION This study demonstrated that the quality of anticoagulation in AF patients newly starting VKAs is sub-optimal. Previous coronary artery disease and concomitant use of amiodarone were identified as independent variables affecting the poor quality of VKA therapy during the first year.

Abstract
PURPOSE Concomitant use of vitamin K antagonists (VKA) and statins is frequent in cardiovascular patients. However, clinical guidelines on this drug combination are divergent. Therefore, we performed a systematic review to evaluate the effect of statin initiation on coagulation among VKA users. METHODS Following the PRISMA guidelines, we applied two broad search strategies for the drug interaction between VKA and statins in both Embase and Pubmed; 8623 unique hits were obtained. In the final sample, eight studies were included. RESULTS The most frequently used VKA in the studies was warfarin, while simvastatin was the most commonly initiated statin. All included studies showed a minor increase in the anticoagulant effect of VKA following statin initiation during VKA treatment. The reported increases in mean international normalized ratio (INR) ranged from 0.15-0.65. CONCLUSION The anticoagulant effect of statin initiation in patients treated with VKA is likely to be of limited clinical relevance but should be evaluated individually.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) represents the later stage consequence of at least one or more unresolved episodes of acute pulmonary embolism; thus, indefinite anticoagulation is strongly recommended by current practice guidelines. Historically, vitamin K antagonists have been widely used in these patients. However, recent data indicate a shift toward direct oral anticoagulants (DOACs), despite lack of data on the safety and efficacy in this patient population. Herein, we briefly discuss the current rationale for oral anticoagulation use in CTEPH, addressing important issues and controversies involved with the use of DOACs, opening a strategy for further clinical research in the field of oral anticoagulation.

Abstract
BACKGROUND The use of direct oral anticoagulants (DOAC) in preference to vitamin K antagonists (VKA) as a treatment of left ventricle (LV) thrombus is controversial. METHODS Literature search for full-text articles and conference abstracts was performed using PubMed, EMBASE databases search was performed to identify articles that compared use of DOAC vs. VKA in patients with LV thrombus. The primary outcome was composite failure or adverse effects of DOAC and VKA. Other outcomes were resolution of thrombus, systemic thromboembolism, major bleeding, and mortality. Pooled odds ratio (OR) with 95% confidence interval (CI) were computed using random effects model. RESULTS Seven studies with 1003 patients (mean age DOAC = 58.8 years and VKA = 58.9 year, 55.5% males) were included in this study. There were 306 (30.5%) patients that were treated with DOAC and 697 (69.5%) patients were treated with VKA. Overall, there were no significant differences between both agents in terms of composite failure/adverse effects, resolution of thrombus, systemic embolism, major bleeding, or mortality. CONCLUSION In this pooled analysis, outcomes in patients on DOAC were comparable to VKA. The hypothesis generated could suggest DOAC could be used interchangeably with VKA in patients with LV thrombus. Randomized trials are needed for generalization of results.
