Background:The current status and outcomes of direct oral anticoagulant (DOAC) use have not been widely evaluated in unselected patients with atrial fibrillation (AF) in the real world.Methods and Results:The Fushimi AF Registry is a community-based prospective survey of AF patients who visited the participating medical institutions (n=80) in Fushimi, Kyoto, Japan. Follow-up data with oral anticoagulant (OAC) status were available for 3,731 patients by the end of November 2015. We evaluated OAC status and clinical outcomes according to OAC status. The number (incidence rate) of stroke/systemic embolism (SE) and major bleeding events during the median follow-up of 3.0 years was 224 (2.3%/year) and 177 (1.8%/year), respectively. After the release of DOAC, the prevalence of DOAC use increased gradually and steadily, and that of warfarin, DOAC and no OAC was 37%, 26% and 36%, respectively in 2015. On Cox proportional hazards modeling incorporating change in OAC status as a time-dependent covariate for stroke/SE and major bleeding events, use of DOAC compared with warfarin was not associated with stroke/SE events (HR, 0.95; 95% CI: 0.59–1.51, P=0.82) or major bleeding events (HR, 0.82; 95% CI: 0.50–1.36, P=0.45).Conclusions:In real-world clinical practice, there were no significant differences in stroke/SE events or major bleeding events for DOAC compared with warfarin in patients with AF.

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:Palliative care is highly relevant for patients with heart failure (HF), and there is a need for quantitative information on quality of care. Accordingly, this study aimed to develop a set of quality indicators (QIs) for palliative care of HF patients, and to conduct a practical pilot measurement of the proposed QIs in clinical practice.Methods and Results:We used a modified Delphi technique, a consensus method that involves a comprehensive literature review, face-to-face multidisciplinary panel meeting, and anonymous rating in 2 rounds. A 15-member multidisciplinary expert panel individually rated each potential indicator on a scale of 1 (lowest) to 9 (highest) for appropriateness. All indicators receiving a median score ≥7 without significant disagreement were included in the final set of QIs. Through the consensus-building process, 35 QIs were proposed for palliative care in HF patients. Practical measurement in HF patients (n=131) from 3 teaching hospitals revealed that all of the proposed QIs could be obtained retrospectively from medical records, and the following QIs had low performance (<10%): “Intervention by multidisciplinary team”, “Opioid therapy for patients with refractory dyspnea”, and “Screening for psychological symptoms”.Conclusions:The first set of QIs for palliative care of HF patients was developed and could clarify quantitative information and might improve the quality of care.

Background:Female sex is considered a risk factor for thromboembolism in patients with atrial fibrillation (AF), and is included in the risk stratification scheme, CHA2DS2-VASc score. The purpose of the present study was to investigate the clinical outcomes of female Japanese AF patients.Methods and Results:The Fushimi AF Registry is a community-based prospective survey of the AF patients in Fushimi-ku, Kyoto. Follow-up data were available for 3,878 patients. Female AF patients (n=1,551, 40.0%) were older (77.0 vs. 71.4 years; P<0.001) than male patients (n=2,327, 60.0%). Female patients were more likely to have heart failure (31.1% vs. 23.7%; P<0.001). Previous stroke incidence (19.2% vs. 21.4%; P=0.083) was comparable between male and female patients. During the median follow-up period of 1,102 days, Cox regression analysis demonstrated that female sex was not independently associated with a risk of stroke or systemic embolism (adjusted hazard ratio [HR] 0.74; 95% confidence interval [CI]: 0.54–1.00, P=0.051). However, female sex showed an association with a lower risk of intracranial hemorrhage (adjusted HR 0.54; 95% CI: 0.30–0.95, P=0.032) and all-cause death (adjusted HR 0.56; 95% CI: 0.46–0.68, P<0.001).Conclusions:We demonstrated that female sex is not independently associated with an increased risk of thromboembolism, but is associated with a decreased risk of intracranial hemorrhage and all-cause death in Japanese AF patients enrolled in the Fushimi AF Registry.

Background:Atrial fibrillation (AF) increases the risk of stroke and death. Oral anticoagulants (OAC) are highly effective in reducing the risk of stroke, and direct oral anticoagulants (DOAC) became available worldwide in 2011.Methods and Results:The Fushimi AF Registry is an on-going prospective survey of AF patients in Fushimi-ku, Kyoto, Japan. The study cohort consisted of 4,489 patients (mean age 73.6 years, 59.6% male, mean CHADS2score 2.03), enrolled in 2011–2017. From 2011 to 2021, antithrombotic therapy has undergone a major transition; the proportion of patients receiving OAC has increased from 53% to 70%, with a steady uptake of DOAC (from 2% to 52%), whereas the proportion of patients receiving antiplatelet agents has decreased from 32% to 14%. Over a median follow-up of 5.1 years, the incidence of stroke/systemic embolism (SE), major bleeding, and all-cause death was 2.2%, 1.9%, and 4.9% per patient-year, respectively. The incidence of stroke/SE (1.6% vs. 2.3%; P<0.01), major bleeding (1.6% vs. 2.0%; P=0.07), and death (4.2% vs. 5.0%; P<0.01) was lower among patients enrolled in 2014–2017 than in 2011–2013, despite comparable baseline characteristics (age 73.2 vs. 73.7 years, CHADS2score 2.03 vs. 2.04, and HAS-BLED score 1.67 vs. 1.77, respectively).Conclusions:Over the past 10 years, there has been a major transition in antithrombotic therapy and a decline in the incidence of adverse events in AF patients.

Background:Japanese patients with atrial fibrillation (AF) are generally small and lean, but knowledge of the clinical characteristics of those with low body weight (LBW: ≤50 kg) is limited.Methods and Results:The Fushimi AF Registry is a community-based prospective survey of AF patients who visited the participating medical institutions in Fushmi-ku, Japan. The BW and follow-up data were available for 2,945 patients. We compared the background and the incidence of clinical events during a median follow-up of 746 days between a LBW and non-LBW group. Patients in the LBW group accounted for 26.8% (788 patients) of the total. The LBW group was more often female, older, and had higher CHADS2score. The incidence of stroke/systemic embolism (SE) during follow-up was higher in the LBW group (hazard ratio (HR): 2.19, 95% confidence interval (CI): 1.57–3.04; P<0.01), whereas that of major bleeding was comparable (HR: 1.05, 95% CI: 0.64–1.68; P=0.84). This trend was consistently observed in the subgroups stratified by age, sex, and oral anticoagulant prescription at baseline. Multivariate analysis as well as propensity-score matching analysis further supported the significance of LBW as a risk of stroke/SE.Conclusions:Patients in the LBW group had high risk profiles and showed a higher incidence of stroke/SE, but the incidence of major bleeding was not particularly high.

Background: Atrial fibrillation (AF) patients often have concomitant coronary artery disease (CAD); however, there are little data on clinical characteristics and outcomes of such patients in daily clinical practice in Japan.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 4,464 patients, and the median follow up was 5.1 (interquartile range: 2.3–8.0) years. History of CAD was present in 647 patients (14%); of those patients, 267 (41%) had history of myocardial infarction (MI). Patients with CAD were older and had more comorbidities than those without CAD. The crude incidences (% per patient-year) of cardiovascular events were significantly higher in patients with CAD than those without CAD (cardiac death: 1.8 vs. 0.7, stroke or systemic embolism [SE]: 2.9 vs. 2.1, MI: 0.6 vs. 0.1, composite of those events: 5.1 vs. 2.8, respectively, all log-rank P<0.01). After multivariate adjustment, concomitant CAD was associated with incidence of cardiac events, and history of MI was associated with incidence of MI; however, neither history of CAD nor MI was associated with the incidence of stroke/SE.Conclusions: In Japanese AF patients, concomitant CAD was associated with higher prevalences of major co-morbidities and higher incidences of cardiovascular events; however, history of CAD was not associated with the incidence of stroke/SE.

Objective The severity of mitral regurgitation (MR) dynamically changes during a stress test. Isometric handgrip is a readily-available stress test in daily practice; however, little is known regarding the response to isometric handgrip in MR patients during right heart catheterization. We aimed to evaluate this issue from our case-series study. Methods We retrospectively investigated consecutive MR patients using the isometric handgrip stress test during right heart catheterization at our institution between October 2019 and April 2021. After resting measurements were obtained, sustained maximum-effort hand dynamometer grasping was maintained for about 2-3 minutes. We investigated the differences in right heart catheterization data between at rest and during handgrip, and evaluated the individual response to the isometric handgrip stress test. Results We investigated a total of 15 patients (mean age: 75±6 years, moderate/severe MR: 7/8, primary/secondary MR: 8/7, mean left ventricular ejection fraction: 56±16%, exertional dyspnea: 10). During the handgrip test, the pulmonary capillary wedge pressure (PCWP) significantly increased [9 (8, 13) mmHg at rest to 20 (15, 27) mmHg during handgrip; p<0.001]. PCWP changes varied among individuals (range 2-22 mmHg) and were not correlated with patients' backgrounds including age, the natriuretic peptide levels, left ventricular ejection fraction, left atrial diameter or E/e' (all p>0.05). Patients with PCWP ≥25 mmHg during handgrip had a higher prevalence of exertional dyspnea than those without [6 (100%) vs. 4 (44%); p=0.04]. Conclusion We observed dynamic and varied hemodynamic changes during isometric handgrip in MR patients, suggesting that further research is needed to evaluate the clinical value of this maneuver.

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.
