Background:Heart failure (HF) is a heterogeneous syndrome, but the effect of the type and severity of HF on the incidence of stroke or systemic embolism (SE) in atrial fibrillation (AF) patients is unclear.Methods and Results:The Fushimi AF Registry is a community-based prospective survey of AF patients in Fushimi-ku, Kyoto, Japan. Follow-up data were available for 3,749 patients. We defined pre-existing HF as having one of the following: prior hospitalization for HF, presence of HF symptoms (NYHA ≥2), or reduced ejection fraction (<40%). At baseline, 1,008 (26.9%) patients had pre-existing HF. On multivariate analysis, the incidence of stroke/SE was not associated with pre-existing HF (hazard ratio (HR), 1.24; 95% confidence interval (CI), 0.92–1.64) or each criterion for the definition of pre-existing HF, but was associated with high B-type natriuretic peptide (BNP) or N-terminal proBNP levels (above the median of the pre-existing HF group) at baseline (HR, 1.65; 95% CI, 1.06–2.53). Stroke/SE was markedly increased in the initial 30-day period following hospital admission for HF (HR, 12.0; 95% CI, 4.59–31.98).Conclusions:The effect of HF on the incidence of stroke/SE may depend on the stage or severity of HF in patients with AF. The incidence of stroke/SE was markedly increased in the 30 days after admission for HF, but compensated ‘stable’ HF did not appear to confer an independent risk.

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

Background: The combination of oral anticoagulant (OAC) and antiplatelet drug (APD) increases the bleeding risk in atrial fibrillation (AF). Non-vitamin K antagonist OAC (NOAC) have been increasingly used since 2011. We investigated current status, time trends and outcomes of AF patients using combination therapy in 2011–2017. Methods and Results: The Fushimi AF Registry is a community-based prospective survey of AF patients in Fushimi-ku, Kyoto, Japan. Of 2,378 patients with OAC at enrollment, 521 (22%) received combination therapy, while 1,857 (78%) received OAC alone. When compared with OAC alone, combination therapy patients had more comorbidities, but approximately 30% had no atherosclerotic disease. From 2011 to 2017, the prevalence of combination therapy decreased from 26% to 14%. The prevalence of NOAC increased in those on combination therapy. Off-label under-dosing of NOAC increased year by year, especially in combination therapy. During follow-up, the incidence of major bleeding (hazard ratio [HR], 1.42; 95% CI: 1.03–1.95) and stroke/systemic embolism (HR, 1.48; 95% CI: 1.09–2.00) was higher in the combination therapy than in the OAC alone group. Conclusions: In Japanese AF patients receiving OAC, the prevalence of combination therapy decreased, with the proportion of NOAC use increasing in 2011–2017. Many patients, however, received off-label NOAC under-dosing, especially in the combination therapy group. Patients with combination therapy had higher incidences of major bleeding as well as stroke/systemic embolism, compared with OAC monotherapy.

Background:Two risk scores have been developed to predict composite outcomes in atrial fibrillation (AF): the 2MACE and TIMI-AF scores. The aim of this study was to compare the predictive ability of these scores in 2 separate warfarin-treated cohorts (one ‘real world’, one clinical trial) of AF patients.Methods and Results:The 2MACE and TIMI-AF scores were calculated in the ‘real-world’ ATHERO-AF cohort (n=907), and in the randomized controlled AMADEUS trial (n=2,265). Endpoints were major adverse cardiovascular events (MACEs), net clinical outcomes (NCO) and a combination of them, namely “clinically relevant events” (CREs). ROC curves showed similar predictive ability for MACE for 2MACE and TIMI-AF, in both the ATHERO-AF (0.698 vs. 0.688, respectively P=0.783) and AMADEUS (0.657 vs. 0.569, respectively P=0.057) cohorts. Similarly, the TIMI-AF showed a comparable c-index with 2MACE for NCOs in the ATHERO-AF (0.676 vs. 0.667, P=0.737), and AMADEUS (0.666 vs. 0.663, P=0.859) cohorts. No differences were found between the 2 scores for the prediction of CREs (0.675 vs. 0.684, P=0.740 in ATHERO-AF and 0.669 vs. 0.667, P=0.889 in AMADEUS for 2MACE and TIMI-AF, respectively).Conclusions:This study showed that the 2MACE and TIMI-AF scores had modest but significant predictive ability for composite outcomes in AF. The clinical usefulness of both scores was similar, but the 2MACE score may be simpler and easy to use.

Background:The ELDERCARE-AF trial demonstrated that low-dose edoxaban prevented stroke or systemic embolism (SE) in very elderly Japanese patients with non-valvular atrial fibrillation (NVAF) in whom standard oral anticoagulant therapy was inappropriate because of high bleeding risk. The aim of this study was to elucidate the characteristics and outcomes of such patients in routine clinical practice.Methods and Results:Data were extracted from the Fushimi AF Registry for ELDERCARE-eligible NVAF patients aged ≥80 years, with a CHADS2score ≥2 and ≥1 bleeding risk factors, as shown in the ELDERCARE-AF trial. ELDERCARE-eligible patients (n=549; 12.8% of the entire cohort, 52.9% of those aged ≥80 years and with CHADS2score ≥2) were less often male, were older, had more comorbidity and higher risk scores than non-eligible patients from the entire cohort (n=3,734). The crude incidence (% per patient-year) of adverse events was significantly higher in ELDERCARE-eligible than non-eligible patients (stroke/SE, 4.8% vs. 2.0%; major bleeding, 3.6% vs. 1.9%; all-cause mortality, 15.5% vs. 3.9%; cardiovascular death, 2.7% vs. 0.6%; all log-rank P<0.001). Compared with non-eligible patients aged ≥80 years and with a CHADS2score ≥2 (n=488), the incidence of stroke/SE, all-cause mortality, and cardiovascular death remained significantly higher in ELDERCARE-eligible patients.Conclusions:Patients with NVAF who met the inclusion criteria of the ELDERCARE-AF trial were common in routine clinical practice, and had poor clinical outcomes.

Background:Several bleeding risk scores have been validated in patients with atrial fibrillation (AF). The ORBIT score has been recently proposed as a simple score with the best ability to predict major bleeding. The present study aimed to test the hypothesis that the ORBIT score was superior to the HAS-BLED score for predicting major bleeding and death in “real world” anticoagulated AF patients.Methods and Results:We analyzed the predictive performance for bleeding and death of 406 AF patients who underwent 571 electrical cardioversion procedures and 1,276 patients with permanent/persistent AF from the FANTASIIA registry. In the cardioversion population, 21 patients had major bleeding events and 26 patients died. The predictive performance for major bleeding of HAS-BLED and ORBIT were not significantly different (c-statistics 0.77 (95% CI 0.66–0.88) and 0.82 (95% CI 0.77–0.93), respectively; P=0.080). For the FANTASIIA population, 46 patients had major bleeding events and 50 patients died. The predictive performances for major bleeding of HAS-BLED and ORBIT were not significantly different (c-statistics 0.63 (95% CI 0.56–0.71) and 0.70 (95% CI 0.62–0.77), respectively; P=0.116). For death, the predictive performances of HAS-BLED and ORBIT were not significantly different in both populations. The ORBIT score categorized most patients as “low risk”.Conclusions:Despite the original claims in its derivation paper, the ORBIT score was not superior to HAS-BLED for predicting major bleeding and death in a “real world” oral anticoagulated AF population.

Background:Non-vitamin K antagonist oral anticoagulants (NOAC) have been developed as alternatives to warfarin. Until recently, the latter was the standard oral anticoagulant for patients with non-valvular atrial fibrillation (NVAF). The efficacy and safety of NOAC in Japanese patients with NVAF has been investigated in small trials or subgroups from global randomized control trials (RCT).Methods and Results:We conducted a systematic review and meta-analysis of RCT, to compare the efficacy and safety of NOAC to those of warfarin in Japanese patients with NVAF. Published research was systematically searched for RCT that compared NOAC to warfarin in Japanese patients with NVAF. Random-effects models were used to pool efficacy and safety data across RCT. Three studies, involving 1,940 patients, were identified. Patients randomized to NOAC had a decreased risk for stroke and systemic thromboembolism (relative risk [RR], 0.45; 95% CI: 0.24–0.85), with a non-significant trend for lower major bleeding (RR, 0.66; 95% CI: 0.29–1.47), intracranial bleeding (RR, 0.46; 95% CI: 0.18–1.16) and gastrointestinal bleeding (RR, 0.52; 95% CI: 0.25–1.08).Conclusions:NOAC are more efficacious than warfarin for the prevention of stroke and systemic embolism in Japanese patients with NVAF. The present findings offer clinicians a more comprehensive picture of NOAC as a therapeutic option to reduce the risk of stroke in Japanese NVAF patients. (Circ J 2015; 79: 339–345)
