Background:Recently, identification of independent risk factors for ischemic stroke in Japanese non-valvular atrial fibrillation (NVAF) patients was made by analyzing the 5 major Japanese registries: J-RHYTHM Registry, Fushimi AF Registry, Shinken Database, Keio interhospital Cardiovascular Studies, and the Hokuriku-Plus AF Registry.Methods and Results:The predictive value of the risk scheme in Japanese NVAF patients was assessed. Of 16,918 patients, 12,289 NVAF patients were analyzed (mean follow up, 649±181 days). Hazard ratios (HRs) of each significant, independent risk factor were determined by using adjusted Cox-hazard proportional analysis. Scoring system for ischemic stroke was created by transforming HR logarithmically and was estimated by c-statistic. During the 21,820 person-years follow up, 241 ischemic stroke events occurred. Significant risk factors were: being elderly (aged 75–84 years [E], HR=1.74), extreme elderly (≥85 years [EE], HR=2.41), having hypertension (H, HR=1.60), previous stroke (S, HR=2.75), type of AF (persistent/permanent) (T, HR=1.59), and low body mass index <18.5 kg/m2(L, HR=1.55) after adjusting for oral anticoagulant treatment. The score was assigned as follows: 1 point to H, E, L, and T, and 2 points to EE and S (HELT-E2S2score). The C-statistic, using this score, was 0.681 (95% confidence interval [CI]=0.647–0.714), which was significantly higher than those using CHADS2(0.647; 95% CI=0.614–0.681, P=0.027 for comparison) and CHA2DS2-VASc scores (0.641; 95% CI=0.608–0.673, P=0.008).Conclusions:The HELT-E2S2score may be useful for identifying Japanese NVAF patients at risk of ischemic stroke.

Background:Because the influence of digitalis use on the death of patients with non-valvular atrial fibrillation (NVAF) remains controversial, a subanalysis of the J-RHYTHM Registry was performed.Methods and Results:A consecutive series of outpatients with AF from 158 institutions was enrolled and followed for 2 years or until the occurrence of an event. Among 7,406 patients with NVAF, 7,018 (age, 69.7±10.0 years; men, 71.1%) with information on antiarrhythmic drug and digitalis use at baseline were divided into 2 groups based on digitalis use. The influence of digitalis on death was investigated using a propensity score-matching model. In 802 patients treated with digitalis, all-cause death was significantly higher than in 6,216 patients with no digitalis use during the 2-year follow-up period (4.4% vs. 2.4%, unadjusted P<0.001). Digitalis use was significantly associated with all-cause death in the crude model (hazard ratio [HR] 1.85, 95% confidence interval [CI] 1.28–2.68, P=0.001). However, after propensity score-matching, the association was not significant (HR 1.31, 95% CI 0.70–2.46, P=0.405). Older age, male sex, heart failure, coronary artery disease, and lower body mass index were significantly associated with all-cause death in NVAF patients treated with digitalis.Conclusions:Digitalis use was not independently associated with all-cause death, and several clinical confounding factors might contribute to increased mortality in NVAF patients treated with digitalis.

Background:Given the high prevalence of heart failure (HF) in the elderly, it is essential to establish medical coordination between general practitioners (GPs) and acute care hospitals (ACHs) in an aging society. The aim of this study was to elucidate the status of acceptance of elderly patients with HF and their management requirements in a comprehensive community health system. Furthermore, we investigated GPs’ interest in using information and communications technology (ICT) in patient care.Methods and Results:We sent a questionnaire survey to 1,800 GPs in January 2015 and received 392 replies. The overall prevalence of home visits was 55%, with no differences according to GP background characteristics or geographic area. However, less than half (44%) reported accepting patients with symptomatic HF for treatment in their clinic. In addition, only 3 GPs reported accepting and providing emergency visits for patients with refractory HF. In particular, GPs who were not certificated cardiologists, female, and older showed poorer acceptance of symptomatic HF patients. More than half the GPs wanted the prompt acceptance by ACHs of emergency patients, followed by strengthening of home care support at discharge and support for end-of-life care. Half the GPs were interested in telemedicine.Conclusions:ACHs must promptly accept patients with HF in cases of emergency and strengthen nursing care support at discharge. It is also necessary to consider how to support older and female GPs.

Background:The J-RHYTHM Registry 2 was a multicenter, prospective observational study that extended the follow-up period of the J-RHYTHM Registry in order to investigate long-term outcomes and effects of non-vitamin K antagonist oral anticoagulants (NOACs) in Japanese patients with atrial fibrillation (AF).Methods and Results:Among 6,616 patients with nonvalvular AF (NVAF) (men 71.0%, 69.7±9.9 years, CHADS2score 1.7±1.2), event rates were compared among patients receiving warfarin (n=3,964), NOACs (n=923), and no anticoagulation therapy (No-OAC, n=753) at the end of follow-up, except for 976 patients lacking anticoagulant data. During the 5-year follow-up period, thromboembolism occurred in 196 (4.9%), 19 (2.1%), and 45 (6.0%) patients, respectively; major hemorrhage in 233 (5.9%), 22 (2.4%), and 36 (4.8%); all-cause death in 230 (5.8%), 13 (1.4%), and 105 (13.9%), (P<0.001 for each). After adjusting for the components of the CHA2DS2-VASc score and antiplatelet drug use, the odds ratio (OR) in the Warfarin group was significantly lower for all-cause death compared with that in the No-OAC group (OR 0.30, 95% confidence interval [CI] 0.23–0.39, P<0.001), whereas ORs in the NOACs group were significantly lower for all events (OR 0.42, 95% CI 0.24–0.74, P=0.003 for thromboembolism; OR 0.53, 95% CI 0.31–0.93, P=0.027 for major hemorrhage; and OR 0.10, 95% CI 0.06–0.18, P<0.001 for all-cause death, respectively).Conclusions:NOACs could be beneficial for reducing event rates of all types in Japanese NVAF patients.

Background:To clarify the effects of warfarin therapy in very old patients with non-valvular atrial fibrillation (NVAF), a post-hoc analysis was performed using the data of the J-RHYTHM Registry.Methods and Results:A consecutive series of AF outpatients was enrolled from 158 institutions. Of 7,937 patients, 7,406 with NVAF (men, 70.8%; 69.8±10.0 years) were followed for 2 years or until an event occurred. Patients were divided into 3 age groups (<70, 70–84, and ≥85 years) and 5 subgroups according to international normalized ratio (INR; <1.6, 1.6–1.99, 2.0–2.59, 2.6–2.99, and ≥3.0). Prevalence of female sex, permanent AF, hypertension, coronary artery disease, heart failure, and history of ischemic stroke/transient ischemic attack was higher in the older groups. In the oldest group, 79.7% of patients received warfarin and their time in therapeutic range, using the Japanese target INR of 1.6–2.6, was 67.1%. Rate of thromboembolic events was lower in the age groups <70 and 70–84 years (P=0.027 and P<0.001, respectively) for patients receiving warfarin compared with those who were not. In the oldest group, the rate of thromboembolism plus major hemorrhage was lower at INR 1.6–2.59.Conclusions:Warfarin could have beneficial effects even in very old NVAF patients if INR is kept between 1.6 and 2.59.

Background:It is unclear whether renal dysfunction affects warfarin control in patients with non-valvular atrial fibrillation (NVAF).Methods and Results:Using a dataset from the J-RHYTHM Registry, time in therapeutic range (TTR) of the international normalized ratio (INR) of prothrombin time, and creatinine clearance (CrCl) were determined in elderly patients aged ≥70 years. Target INR values were 1.6–2.6 following Japanese guidelines. Incidences of thromboembolism, major hemorrhage, and all-cause death were determined over 2 years. Of 7,406 NVAF patients enrolled in the registry, 2,782 elderly patients (mean age, 75 years) had data for CrCl measured at baseline and TTR. TTR values were lower in the lower CrCl groups (P<0.001 for trend). CrCl <30 mL/min was independently associated with TTR <65% (odds ratio, 1.49; 95% confidence interval, 1.13–1.95; P=0.004). In the multivariate analysis, TTR <65% was independently associated with thromboembolism (hazard ratio, 2.26; 95% confidence interval, 1.37–3.72; P=0.001), but CrCl was not (CrCl <30 mL/min, 1.68, 0.41–6.85, P=0.473). However, CrCl <30 mL/min and TTR <65% were independently associated with all-cause death (5.32, 1.56–18.18, P=0.008 and 1.60, 1.07–2.38, P=0.022, respectively) and the composite event (thromboembolism, major hemorrhage and all-cause death) (2.03, 1.10–3.76, P=0.024 and 1.58, 1.22–2.04, P=0.001, respectively).Conclusions:Elderly NVAF patients with renal dysfunction had poor warfarin control, which was associated with higher risk of thromboembolism and all-cause death.

Music therapy (MT) has been used in geriatric nursing hospitals, but there has been no extensive research into whether it actually has beneficial effects on elderly patients with cerebrovascular disease (CVD) and dementia. We investigated the effects of MT on the autonomic nervous system and plasma cytokine and catecholamine levels in elderly patients with CVD and dementia, since these are related to aging and chronic geriatric disease. We also investigated the effects of MT on congestive heart failure (CHF) events.Eighty-seven patients with pre-existing CVD were enrolled in the study. We assigned patients into an MT group (n = 55) and non-MT group (n = 32). The MT group received MT at least once per week for 45 minutes over 10 times. Cardiac autonomic activity was assessed by heart rate variability (HRV). We measured plasma cytokine and catecholamine levels in both the MT group and non-MT group. We compared the incidence of CHF events between these two groups. In the MT group, rMSSD, pNN50, and HF were significantly increased by MT, whereas LF/HF was slightly decreased. In the non-MT group, there were no significant changes in any HRV parameters. Among cytokines, plasma interleukin-6 (IL-6) in the MT group was significantly lower than those in the non-MT group. Plasma adrenaline and noradrenaline levels were significantly lower in the MT group than in the non-MT group. CHF events were less frequent in the MT group than in the non-MT group (P < 0.05). These findings suggest that MT enhanced parasympathetic activities and decreased CHF by reducing plasma cytokine and catecholamine levels.

Background:Recently, identification of independent risk factors for ischemic stroke in Japanese non-valvular atrial fibrillation (NVAF) patients was made by analyzing the 5 major Japanese registries: J-RHYTHM Registry, Fushimi AF Registry, Shinken Database, Keio interhospital Cardiovascular Studies, and the Hokuriku-Plus AF Registry.Methods and Results:The predictive value of the risk scheme in Japanese NVAF patients was assessed. Of 16,918 patients, 12,289 NVAF patients were analyzed (mean follow up, 649±181 days). Hazard ratios (HRs) of each significant, independent risk factor were determined by using adjusted Cox-hazard proportional analysis. Scoring system for ischemic stroke was created by transforming HR logarithmically and was estimated by c-statistic. During the 21,820 person-years follow up, 241 ischemic stroke events occurred. Significant risk factors were: being elderly (aged 75–84 years [E], HR=1.74), extreme elderly (≥85 years [EE], HR=2.41), having hypertension (H, HR=1.60), previous stroke (S, HR=2.75), type of AF (persistent/permanent) (T, HR=1.59), and low body mass index <18.5 kg/m2(L, HR=1.55) after adjusting for oral anticoagulant treatment. The score was assigned as follows: 1 point to H, E, L, and T, and 2 points to EE and S (HELT-E2S2score). The C-statistic, using this score, was 0.681 (95% confidence interval [CI]=0.647–0.714), which was significantly higher than those using CHADS2(0.647; 95% CI=0.614–0.681, P=0.027 for comparison) and CHA2DS2-VASc scores (0.641; 95% CI=0.608–0.673, P=0.008).Conclusions:The HELT-E2S2score may be useful for identifying Japanese NVAF patients at risk of ischemic stroke.
