Abstract Background Patients with atrial fibrillation (AF) commonly coexist with chronic kidney disease (CKD). Non-vitamin K antagonist oral anticoagulants (NOAC) are recommended for stroke prevention in patients with non-valvular atrial fibrillation (AF), and worsening renal function (WRF) as well as CKD is an important issue in using NOAC. However, little is known about the clinical outcomes of patients after WRF. Purpose We aimed to investigate outcomes after WRF in AF patients. Methods The Fushimi AF Registry is a community-based prospective survey of the AF patients in our city. Follow-up data including prescription status were available for 4,441 patients. Of them, 1,890 patients who have baseline and at least 1 follow-up creatinine clearance (CrCl) measurements, estimated by the Cockcroft-Gault formula, were analyzed in the present study. WRF was defined as a decrease of ≥20% from baseline CrCl measurement at any time point during follow-up. We evaluated demographics and outcomes after WRF in AF patients. Results During the median follow-up period of 2,194 days, mean CrCl decrease of 2.2 ml/min/year was observed and WRF occurred in 981 patients (51.9%). Patients with WRF were significantly more often female (with vs. without WRF; 40.3% vs. 35.4%; p=0.03), older (73.4 vs. 71.1 years of age; p<0.01), more often paroxysmal type (49.9% vs. 47.1%; p<0.01), and more likely to have prior stroke (17.9% vs. 12.7%; p<0.01), heart failure (30.8% vs. 24.8%; p<0.01), diabetes (31.7% vs. 27.1%; p=0.03), and coronary artery disease (19.9% vs. 12.1%; p<0.01) than those without WRF. Co-existing of CKD and mean CrCl at baseline were comparable (37.4% vs. 36.9%; p=0.82, 65.3 vs. 63.5 ml/min; p=0.66, respectively). Mean CHA2DS2-VASc score was significantly higher in WRF patients (3.55 vs. 3.03; p<0.01). On landmark analysis, all-cause mortality occurred in 135 patients (8.6 /100 person-years) after WRF and 82 patients (1.7 /100 person-years) without WRF, with an adjusted hazard ratio (HR) of 6.33 (95% confidence interval [CI], 4.33–9.50; p<0.01), adjusted by sex, age, body weight, serum creatinine, type of AF, oral anticoagulant prescription and comorbidities. Stroke or systemic embolism occurred in 45 patients after WRF (3.0 /100 person-years) and 78 (1.7 /100 person-years) patients without WRF (adjusted HR 1.60 [95% CI, 1.04–2.49; p=0.03]) (Figure).

Background: Atrial fibrillation (AF) and chronic kidney disease (CKD) often coexist, but the real-world data after approval of direct oral anticoagulants (DOACs) are still lacking in Japan. We investigated the association of the baseline renal function and adverse clinical events and risk of adverse clinical events with DOACs compared to warfarin for each renal functional level in Japanese AF patients. Methods: The present substudy was based on the SAKURA AF Registry, a Japanese multicenter observational registry (median follow-up period: 39 months). The creatinine clearance (CrCl) values were estimated by the Cockcroft–Gault formula, and divided into normal renal function, and mild and moderate-severe CKD (CrCl ≥ 80, 50–79, <50 mL/min). Results: In the SAKURA AF Registry, the baseline CrCl data were available for 3242 patients (52% for DOAC and 48% for warfarin user). The relative risk of adverse clinical events was significantly higher in the patients with a CrCl < 50 mL/min as compared to those with a CrCl ≥ 80 mL/min (adjusted HRs: 2.53 for death, 2.53 for cardiovascular [CV] events, 2.13 for strokes, and 1.83 for major bleeding). Risks of all adverse clinical events were statistically even between DOAC and warfarin users for each renal function level. Conclusion: Moderate–severe CKD was associated with a higher mortality, CV events, strokes, and major bleeding than normal renal function. The safety and effectiveness of DOACs over warfarin were similar for each renal function level. By a worsening renal function, the incidence of adverse clinical events increased, especially deaths and CV events as compared to strokes and major bleeding.

Abstract Background Direct oral anticoagulants (DOAC) are indicated for stroke prophylaxis in non-valvular atrial fibrillation, which is responsible for up to 20% of all ischaemic strokes(1). We performed a retrospective audit of all consecutive stroke patients in an Irish teaching hospital over a 1-year period to investigate the rate of incorrect dosing and any risk factors for this occurring. Methods We assessed our hospital stroke database from January to December 2017. Our research focused on DOAC prescribing in non valvular atrial fibrillation post embolic stroke. We collected data on baseline characteristics, choice of anticoagulation, dosing, and assessment of renal function, with follow up renal function if available. We reviewed electronic discharge summaries, online laboratory systems and completed a chart review. Results There was a total of 116 people with atrial fibrillation who developed an embolic stroke in our centre, of which 68 were eligible for anticoagulation using a DOAC (59). The main reasons for omission were CKD and haemorrhagic transformation. Patients were discharged on either Apixaban (32 patients), Rivaroxoban (32 patients), or Dabigatran (4 patients). Following our review, we established that 54/68 (79%) of patients were correctly anticoagulated. Over 20% of patients were incorrectly dosed and there was a clear tendency to under-dose 13/14 (93%). There were significant differences between the correct and incorrect dosing groups, with the latter group of patients being older and more at risk of polypharmacy. Renal function did not differ significantly between the groups at discharge or follow up and none of the incorrectly dosed patients were on a concurrent anti platelet. Conclusion A significant number of patients prescribed DOAC in hospital were not appropriately anticoagulated (21%), a majority of which were under-dosed. The patients who were under-dosed were older and more likely to be on 5 or more medications.

Background: Older adults with atrial fibrillation (AF) are often treated with the shortest possible duration of antiplatelet/anticoagulant therapy after myocardial infarction (MI) or percutaneous coronary intervention (PCI) due to concern for bleeding. However, the risk of recurrent MI or PCI prompting antiplatelet therapy extension is unknown in this population. Methods: Using the National Cardiovascular Data Registry linked to Medicare claims, we described the cumulative incidence of recurrent MI or PCI over a median of 7-year follow-up for patients ≥65 years old with AF discharged alive after acute MI between 2008 and 2017. We used pharmacy fill data to describe the proportion of patients filling prescriptions for both oral anticoagulants and P2Y 12 inhibitors for ≥50% of the indicated duration after MI or PCI. Results: Of 187 622 older patients discharged alive after MI, 50 539 (26.9%) had AF. Over a median of 7-year follow-up in patients with AF, the cumulative incidence was 14.5% for recurrent MI, 12.1% for PCI, 7.9% for stroke, and 9.5% for bleeding hospitalization. Among 7998 patients with AF and recurrent MI or PCI, 1668 (20.9%) had >1 MI or PCI during follow-up. Assuming each MI or PCI should be followed by 6 months of P2Y 12 inhibitor therapy, patients with AF who had a recurrent MI/PCI had a median estimated indication for antiplatelet/anticoagulant treatment of 287 days (194, 358), but filled both P2Y 12 inhibitor and oral anticoagulant for a median of 0 days (0, 21). In this cohort, 12.2% of patients filled prescriptions for both a P2Y 12 inhibitor and oral anticoagulant for ≥50% of the indicated duration. Conclusions: Older adults with AF and MI have high incidences of downstream recurrent MI or PCI requiring extended antiplatelet/anticoagulant therapy durations, yet many appear to be under-treated. These results highlight the need for better thrombosis prevention strategies in this group of patients.

ObjectiveNon-vitamin K oral anticoagulants (NOACs) require dose adjustment for renal function. We sought to investigate change in renal function over time in patients with atrial fibrillation (AF) and whether those on NOACs have appropriate dose adjustments according to its decline.MethodsWe included patients with AF enrolled in the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation II registry treated with oral anticoagulation. Worsening renal function (WRF) was defined as a decrease of >20% in creatinine clearance (CrCl) from baseline. The US Food and Drug Administration (FDA)-approved package inserts were used to define the reduction criteria of NOACs dosing.ResultsAmong 6682 patients with AF from 220 sites (median age (25th, 75th): 72.0 years (65.0, 79.0); 57.1% male; median CrCl at baseline: 80.1 mL/min (57.4, 108.5)), 1543 patients (23.1%) experienced WRF with mean decline in CrCl during 2 year follow-up of −6.63 mL/min for NOACs and −6.16 mL/min for warfarin. Among 4120 patients on NOACs, 154 (3.7%) patients had a CrCl decline sufficient to warrant FDA-recommended dose reductions. Of these, NOACs dosing was appropriately reduced in only 31 (20.1%) patients. Compared with patients with appropriately reduced NOACs, those without were more likely to experience bleeding complications (major bleeding: 1.7% vs 0%; bleeding hospitalisation: 2.6% vs 0%) at 1 year.ConclusionsIn the US practice, about one-fourth of patients with AF had >20% decline in CrCl over time during 2 year follow-up. As a result, about 3.7% of those treated with NOACs met guideline criteria for dose reduction, but of these, only 20.1% actually had a reduction.

Abstract Background Renal function is a major determinant of major adverse outcomes in patients with atrial fibrillation (AF). Scarce data are available about the impact of renal function trajectories and creatinine clearance (CrCl) temporal variability, on prognosis. Aim To evaluate the progression and impact of renal function impairment and variability on outcomes over a long-term follow-up observation in a cohort of anticoagulated AF patients. Methods We included warfarin-treated AF patients in SPORTIF trials with available creatinine clearance (according to Cockroft-Gault) at baseline and at least 4 evaluations throughout their follow-up. Patients with a BMI ≥45 kg/m2 were excluded from the analysis. Average successive variability (ASV) was used as measure of variability. Results Among 3665 original patients, 3366 (91.8%) were included in this analysis. Median [IQR] CHA2DS2-VASc score was 3 [2–4] and HAS-BLED was 3 [2–4]. At baseline, 876 (26.0%) patients had CKD (CrCl &lt;60 mL/min), with 14 (0.4%) patients having severe CKD (&lt;30 mL/min), with a mean (SD) CrCl of 86.7 (47.4) mL/min. Over a mean (SD) 577.1 (122.1) days of follow-up, a total of 521 new CKD cases were found with an overall incidence of 13.1 per 100 patient-years, with 91 new severe CKD cases (1.71 per 100 patient-years). Across follow-up, prevalence of CKD and severe CKD increased progressively (both p&lt;0.001) [Figure]. Mean (SD) AVS was −0.567 (±2.803) mL/min. According to AVS, patients were divided into quartiles: i) Q1: +34.012/+0.450; ii) Q2: +0.449/−0.443; iii) Q3: −0.443/−1.503; Q4: −1.505/−19.750. While no difference was found in stroke/systemic embolism, rate of major bleeding was higher in Q4 (4.5%) and Q1 (4.0%) than in other quartiles (Q2 2.5%, Q3 2.0%; p=0.009) as well as all-cause death (Q4: 6.7%; p=0.003 compared to other quartiles). A Cox multivariate adjusted model documented that AVS Q1 and Q4 were independently associated with a higher risk of major bleeding, while Q4 was associated with a higher risk of all-cause death (Table). Conclusion In a cohort of AF patients treated with warfarin, characterized by a progressive increase in the proportion with CKD and severe CKD, the largest reduction in CrCl throughout follow-up was associated to an increased risk of major bleeding and all-cause death.

Abstract Background Atrial fibrillation (AF) is associated with a high risk of stroke and mortality. Some years ago, the EURObservational Research Programme launched the General Long-Term Registry with the aim to evaluate contemporary management of AF patients in Europe, the current use of vitamin K antagonists (VKAs), direct-acting oral anticoagulants (DOACs) and other AF treatments, in relation to guideline recommendations. Purpose The present report aims to describe the characteristics of a large database on the management of AF in Spain, using the Spanish cohort included in the EORP-AF Long-Term Registry. Methods The EORP-AF Long-Term General Registry is a prospective, observational, large-scale multicentre registry sponsored and conducted by the ESC, enrolling AF patients in current cardiology practices in 250 centres from 27 participating ESC countries. Patients were enrolled consecutively when presenting with AF as primary or secondary diagnosis to inpatients and outpatient cardiology services from October 2013 to September 2016. The first Spanish patient in the EORP-AF Long-Term Registry was included in 2014. Initially, the aim was to carry out a follow-up up to 3 years but this was reduced to 2 years by the Executive Committee. To date, only data from the first year of follow-up is available for the Spanish cohort. Results A cohort of 729 AF Spanish patients was included (57.1% male, median age 75 [IQR 67–81] years, median CHA2DS2-VASc and HAS-BLED of 3 [IQR 2–5] and 2 [IQR 1–2], respectively). A relatively low proportion of patients (634, 87%) received oral anticoagulants (OACs), of which 389 (53.4%) were on VKAs and 245 (33.6%) were on DOACs (rate ratio = 1.59 [95% CI 1.35–1.87], p&lt;0.001). Importantly, there were 98 (13.4%) patients taking concomitantly antiplatelet therapy and OACs; as well as 5.5% of patients were taking parenteral anticoagulation or antiplatelets alone. After 1 year, the proportion of patients on OACs increased from 87.0% to 88.1%. The proportion of DOACs users increased from 33.6% at baseline to 39.9%, partly due to switches from VKA to DOACs in relation to poor time in therapeutic range. At the same time, 34 (4.7%) patients withdrew OACs. During the first year of follow-up, 48 patients (6.6%) died, 7 (1.0%) suffered ischemic strokes and 6 (0.8%) transient ischemic attacks. Of note, there was a substantial rate of major bleeds (ISTH criteria) (57, 7.8%), of which 10 (1.4%) were intracranial haemorrhages. Conclusions Baseline data of the Spanish cohort are similar to that reported for the whole EORP cohort, including similar stroke and bleeding risks. OAC use slightly increased at 1-year, with low discontinuation rates which could be related with a low incidence of thromboembolic events. However, despite the ∼8% rate of major bleeding in overall, the use of a safer therapy such as DOACs is still low compared to VKAs, being the antiplatelets commonly used concomitantly with OACs Funding Acknowledgement Type of funding source: Private grant(s) and/or Sponsorship.

Abstract Introduction Age is a strong independent risk factor for stroke and systemic embolism (SE) in patients with atrial fibrillation (AF). Reducing risk of stroke/SE with oral anticoagulation (OAC) in elderly patients involves a correspondingly greater risk of bleeding than in younger patients. Non-vitamin K antagonist oral anticoagulants (NOACs) are associated with a net clinical benefit over vitamin K antagonists in the elderly population, but knowledge is lacking about the comparative effectiveness and safety between specific oral anticoagulants in these patients. Purpose The aim of this study was to compare the rates of stroke/SE and major bleeding between new users of warfarin, dabigatran, rivaroxaban, and apixaban, in a nationwide cohort of AF patients over 75 years. Methods From Norwegian national registries we identified all anticoagulant naïve initiators of warfarin, dabigatran, rivaroxaban and apixaban over 75 years of age between January 2013 and December 2017. During follow-up, patients were censored upon switching OAC, discontinuation of OAC, death, or end of study period. Multivariate competing risk regression was used to evaluate association between treatment and the outcomes stroke/se and major bleeding, treating death as a competing risk. Results A total of 30 401 patients were identified; 6 650 starting warfarin, 3 857 starting dabigatran, 6 108 starting rivaroxaban, and 13 786 starting apixaban. The median age was 82 years. Dabigatran-users had less comorbidity than all other OAC-users; the greatest difference was seen in the proportion of patients with chronic kidney disease (4.3% in the dabigatran-group versus 7.0%, 10.5%, and 16.5% in the rivaroxaban, apixaban, and warfarin groups, respectively). The median follow-up time was 15 months, during which time 1 386 (4.6%) patients suffered a stroke/SE; 1 277 (4.2%) patients had a major bleeding episode; and 3 270 (10.8%) died. Adjusted subhazard ratios for stroke/SE and major bleeding are presented in the figure. Conclusion Comparing NOACs with warfarin, we found no significant differences in risk of stroke/SE, while apixaban was associated with lower risk of major bleeding than warfarin. Comparing NOACs with each other; dabigatran was associated with a significantly lower risk of stroke/SE compared with rivaroxaban and apixaban, while both dabigatran and apixaban were associated with significantly lower risks of major bleeding compared with rivaroxaban.

Abstract Background The prevalence of atrial fibrillation (AF) and the need for appropriate anticoagulation increase with age. The benefit/risk profile of direct oral anticoagulants such as edoxaban in elderly population with AF in regular clinical practice is therefore of particular interest. Purpose Analyses of Global ETNA-AF data were performed to report patient characteristics, edoxaban treatment, and 1-year clinical events by age subgroups. Methods Global ETNA-AF is a multicentre, prospective, noninterventional program conducted in Europe, Japan, Korea, Taiwan, and other Asian countries. Demographics, baseline characteristics, and 1-year clinical event data were analysed in four age subgroups. Results Of 26,823 patients included in this analysis, 50.4% were ≥75 years old and 11.6% were ≥85 years. Increase in age was generally associated with lower body weight, lower creatinine clearance, higher CHA2DS2-VASc and HAS-BLED scores, and a higher percentage of patients receiving the reduced dose of 30 mg daily edoxaban. At 1-year, rates of ISTH major bleeding and ischaemic stroke were generally low across all age subgroups. The proportion of intracranial haemorrhage within major bleeding events was similar across age groups. All-cause mortality increased with age more than cardiovascular mortality. Conclusion Data from Global ETNA-AF support the safety and effectiveness of edoxaban in elderly AF patients (including ≥85 years) in routine clinical care with only a small increase in intracranial haemorrhage. The higher all-cause mortality with increasing age is not driven by cardiovascular causes. Funding Acknowledgement Type of funding source: Private company. Main funding source(s): Daiichi Sankyo

Abstract Background/Introduction Cross-sectional studies are inconsistent on the potential independent adverse effects of human immunodeficiency virus (HIV)-infection on coronary artery disease (CAD). Furthermore, there is no information on the potential effects of HIV-infection on plaque volumes. Also, only the independent effects of HIV-infection on CAD have been investigated. Purpose In a prospective longitudinal observational cohort, we wished to assess whether HIV-infection accelerates CAD independently, or by acting in synergistic fashion with conventional and nonconventional cardiovascular risk factors to accelerate disease progression as assessed by clinical and volumetric parameters of CAD on coronary CT angiography (CCTA). Methods Overall, 300 asymptomatic individuals without cardiovascular symptoms but with CCTA-confirmed coronary plaques (210 males, age: 48.0±7.2 years) with or without HIV (226 HIV-infected) prospectively underwent CCTA at two time points (mean follow-up: 4.0±2.3 years). Agatston-score, number of coronary plaques, segment stenosis score were calculated, and we also segmented the coronary plaques to enumerate total, noncalcified (−100–350HU) and calcified (≥351HU) plaque volumes. Linear mixed models were used to assess the effects of HIV-infection, atherosclerotic cardiovascular disease (ASCVD) risk, years of cocaine use and high-sensitivity C-reactive protein on CCTA markers of CAD. Results In univariate analysis, there was no significant difference in CAD characteristics between HIV-infected and -uninfected, neither at baseline nor at follow-up (p&gt;0.05 for all). Furthermore, there was no significant difference in annual progression rates between the two groups (p&gt;0.05 for all). By multivariate analysis, HIV was not associated with any CAD parameter (p&gt;0.05 for all). However, among HIV-infected individuals, each year of cocaine use significantly increased all CAD parameters (p&lt;0.05 for all), while ASCVD risk score was significantly associated with CAD parameters except for Agatston-score (p&lt;0.05). These associations were only present among HIV-infected individuals. Conclusion(s) Instead of directly worsening CAD, HIV may promote CAD through increased susceptibility to conventional and nonconventional cardiovascular risk factors. Therefore, aggressive management of both conventional and nonconventional cardiovascular risk factors is needed to reduce cardiovascular burden of HIV-infection.
