Background: There is a scarcity of reports on the clinical characteristics and management practice in contemporary all-comer patients with acute decompensated heart failure (ADHF). Methods and ...Results: The Kyoto Congestive Heart Failure (KCHF) registry is a prospective observational cohort study enrolling 4,056 consecutive patients who had hospital admission due to ADHF without any exclusion criteria between October 2014 and March 2016 in the 19 participating hospitals in Japan. Baseline characteristics, clinical presentations, management, and in-hospital outcomes were compared between heart failure (HF) with reduced left ventricular ejection fraction (LVEF; HFrEF, LVEF <40%), HF with mid-range LVEF (HFmrEF, LVEF 40–49%), and HF with preserved LVEF (HFpEF, LVEF ≥50%). Of the 4,041 patients with documented LVEF, 1,744 (43%) had HFpEF; 746 (19%), HFmrEF; and 1,551 (38%), HFrEF. The median age was 80 years (IQR, 72–86 years) in the entire population, and was higher with increasing LVEF (P<0.001). The in-hospital mortality rate was higher in the HFrEF than in the HFmrEF and HFpEF groups (9.2%, 4.8%, and 5.1%, respectively, P<0.001). Conclusions: This registry elucidated the clinical features and clinically relevant in-hospital outcomes in contemporary consecutive patients with ADHF in real-world clinical practice in Japan. When classified by LVEF, significant differences in characteristics and in-hospital outcomes existed between patients with HFrEF, HFmrEF, and HFpEF.
The high controlling nutritional status (CONUT) score that represents poor nutritional status has been acknowledged to have prognostic implications in chronic heart failure. We aimed to investigate ...its role in acute decompensated heart failure (ADHF). Using the data from an multicenter registry that enrolled 4056 consecutive patients hospitalized for ADHF in Japan between 2014 and 2016, we analyzed 2466 patients in whom data on the components of the CONUT score at hospital presentation were available. The decrease of lymphocyte count and total cholesterol was assigned with 0, 1, 2, and 3 points and the decrease of albumin was assigned with 0, 2, 4, and 6 points according to the severity. We defined low CONUT score as 0-4 (N = 1568) and high CONUT score as 5-9 (N = 898). The patients in the high CONUT score group were older and more likely to have a smaller body mass index than those in the low CONUT score group. The high CONUT score group was associated with higher rate of death and infection during the index hospitalization compared to the low CONUT score group (9.0% versus 4.4%, and 21.9% versus 12.7%, respectively). After adjusting for confounders, the excess risk of high relative to low CONUT score for mortality and infection was significant (OR: 1.61, 95%CI: 1.05-2.44, and OR: 1.66, 95%CI: 1.30-2.12, respectively). The effect was incremental according to the score. High CONUT score was associated with higher risk for in-hospital mortality and infection in an incremental manner in patients hospitalized for ADHF.
•Heart failure (HF) is a quintessential cardiovascular syndrome of aging.•HF adversely affects the physical and psychological problems of a patient's life in older adults.•The basic idea of Kampo is ...that a balance of physical and mental is essential for human health.•A holistic approach using Kampo can be helpful to improve quality of life and outcomes in older patients with HF.•Further evidence needs to be generated for the effects of Kampo medicine on elderly HF patients.
Heart failure (HF) is a leading cause of hospitalization, morbidity, and mortality in older adults and represents a significant clinical and economic burden on the health care system. However, there are many challenges in assessing and managing HF in elderly patients, who often have coexisting multimorbidity, frailty, and malnutrition. Therefore, it is often difficult to solve these problems with Western medicine alone, and a holistic approach, including Kampo medicine, can be helpful. In particular, managing volume control and frailty by adding Kampo formulas may help improve health-related quality of life and substantially impact prognosis in HF. This review article summarizes the role of Kampo medicine for older patients with HF and frailty.

We aimed to investigate the relationship between left atrial (LA) reverse remodeling and prognosis of heart failure (HF) with recovered ejection fraction (EF) (HFrecEF). Among 1,246 patients with ...acute heart failure enrolled in the prospective longitudinal follow-up study, 397 patients with HF with mildly-reduced EF and with reduced EF at discharge were analyzed. Echocardiography was performed during the index hospitalization and at the 6-month follow-up after discharge. They were divided into non-HFrecEF (n = 227) and HFrecEF (n = 170) groups. The primary outcome measure was a composite of all-cause death or hospitalization for HF. The cumulative 180-day incidence of the primary outcome measure after follow-up echocardiography was significantly lower in the HFrecEF group than in the non-HFrecEF group (8.9% versus 23.4%, log-rank P = 0.0002). LA reverse remodeling was associated with a lower cumulative 6-month incidence of the primary outcome measure in the HFrecEF group (4.7% versus 18.0%; HR: 0.27, 95%CI: 0.09-0.79, P = 0.01), but not in the non-HFrecEF group (24.4% versus 22.6%; HR: 1.13, 95%CI: 0.65-1.96, P = 0.28) with a significant LA reverse remodeling-by-HFrecEF interaction (P for interaction = 0.02). Combination of left ventricular and atrial reverse remodeling may help in improving HF risk stratification.
The prognostic implication of weight loss after discharge from acute heart failure (AHF) remains unclear. We sought to investigate the association of weight loss between discharge and 6-month visit ...with subsequent clinical outcomes in patients with AHF.
We analyzed 686 patients with AHF in the prospective longitudinal follow-up study derived from the Kyoto Congestive Heart Failure registry, and divided them into 2 groups based on the weight loss at 6-month index visit. We defined the weight loss as ≥ 5% decrease in body weight from discharge to 6-month index visit.
There were 90 patients (13.1%) with a weight loss at 6-month visit. Patients in the weight loss group compared with those in the no weight loss group had higher body weight at discharge and lower body weight at 6-mont visit. Patients in the weight loss group had a lower systolic blood pressure, higher brain-type natriuretic peptide, lower serum albumin, lower hemoglobin, higher prevalence of heart failure with reduced ejection fraction at 6-month visit, and a lower prescription rate of inhibitors of renin-angiotensin system than those in the no weight loss group. The cumulative 6-month incidence of all-cause death was significantly higher in the weight loss group than in the no weight loss group (14.2% and 4.3%, log-rank P<0.001). The excess adjusted risk of the weight loss group relative to the no weight loss group remained significant for all-cause death (HR 2.39, 95%CI 1.01-5.65, P = 0.048).
Body weight loss of ≥5% at 6-month visit after discharge was associated with subsequent all-cause death in patients with AHF.
Background Recently, direct oral anticoagulants have been introduced for venous thromboembolism (VTE), which might change the management strategies of VTE. However, there have been limited data on ...the current real-world practice pattern for VTE in Asian countries. Methods and Results The JROAD-DPC (Japanese Registry of All Cardiac and Vascular Diseases\xF6Diagnosis Procedure Combination) is a nationwide claim database from 1022 hospitals in Japan between April 2012 and March 2017. We identified 54 369 patients who were hospitalized with a diagnosis of VTE at admission based on the
(
) code. The mean age was 69.1±15.6 years, 59% were women, and mean body mass index was 23.5±5.0 kg/m
. The proportion of patients with deep vein thrombosis decreased over time from 72% in 2012 to 38% in 2017. After the release of direct oral anticoagulants, the proportion of patients receiving direct oral anticoagulants increased dramatically among patients with anticoagulation therapy at discharge with the use of edoxaban, rivaroxaban, and apixaban in 35%, 22%, and 27% of patients, respectively, in 2017. On the other hand, the proportion of patients receiving warfarin decreased from 94% in 2012 to 15% in 2017. The median length of a hospital stay decreased over time from 20 days in 2012 to 13 days in 2017 in patients with pulmonary embolism, and from 14 days in 2012 to 12 days in 2017 in patients with deep vein thrombosis. The median cost of hospitalization for pulmonary embolism moderately decreased over time, whereas that for deep vein thrombosis slightly decreased over time. Conclusions A nationwide claim-based database provided the current practice pattern for VTE in Japan, which revealed dynamic changes after the release of direct oral anticoagulants.

Background:The effect of diabetes mellitus (DM) status on the long-term risk for heart failure (HF) in patients undergoing coronary revascularization has not been adequately evaluated.Methods and ...Results:In this study, 15,231 patients who underwent coronary revascularization in the CREDO-Kyoto Registry Cohort-2 were divided into 2 groups according to DM status (DM group: n=5,999; Non-DM group: n=9,232). The DM group was further divided into 2 groups according to insulin treatment (insulin-treated DM ITDM: n=1,353; non-insulin-treated DM NITDM: n=4,646). The primary outcome measure was HF hospitalization. The cumulative 5-year incidence of HF hospitalization was significantly higher in the DM than non-DM group (11.0% vs. 6.6%, respectively; log-rank P<0.0001), and in the ITDM than NITDM group (14.6% vs. 10.0%, respectively; log-rank P<0.0001). After adjusting for confounders, the increased risk of HF hospitalization with DM relative to non-DM remained significant (hazard ratio HR 1.47, 95% confidence interval CI 1.30–1.67, P<0.0001), whereas the risk associated with ITDM relative to NITDM was not significant (HR 1.17, 95% CI 0.96–1.43, P=0.12).Conclusions:The adjusted long-term risk for HF hospitalization after coronary revascularization was significantly higher in DM than non-DM patients, regardless of revascularization strategy, but did not differ between ITDM and NITDM patients.
Objective This observational study aimed to examine the prognostic association of angiotensin-converting enzyme inhibitors (ACE-I)/angiotensin receptor blockers (ARB) in different left ventricular ...ejection fraction (LVEF) categories. Methods In 3717 patients enrolled in the KCHF Registry, a multicentre registry including consecutive patients hospitalized for acute heart failure (HF), we assessed patient characteristics and association between ACE-I/ARB and clinical outcomes according to LVEF. In the three LVEF categories (reduced LVEF HFrEF, mid-range LVEF HFmrEF and preserved LVEF HFpEF), we compared the patients with ACE-I/ARB as discharge medication and those without, and assessed their 1-year clinical outcomes. We defined the primary outcome measure as a composite of all-cause death and HF hospitalization. Results The 1-year cumulative incidences of the primary outcome measure were 36.3% in HFrEF, 30.1% in HFmrEF and 33.8% in HFpEF (log-rank P = 0.07). The adjusted risks of the ACE-I/ARB group relative to the no ACE-I/ARB group for the primary outcome measure were significantly lower in HFrEF and HFmrEF (HR 0.66 95%CI 0.54-0.79, P0.001, and HR 0.61 0.45-0.82, P = 0.001, respectively), but not in HFpEF (HR 0.95 0.80-1.14, P = 0.61). There was a significant interaction between the LVEF category and the ACE-I/ARB use on the primary outcome measure (P.sub.interaction = 0.01). Conclusions ACE-I/ARB for patients who were hospitalized for acute HF was associated with significantly lower risk for a composite of all-cause death and HF hospitalization in HFrEF and HFmrEF, but not in HFpEF. ACE-I/ARB might be a potential treatment option in HFmrEF as in HFrEF.
Activated clotting time (ACT) kinetics under uninterrupted oral anticoagulants (OACs) has not been fully evaluated. The present study is sought to validate ACT kinetics including stability under ...uninterrupted use of OACs during an ablation procedure in daily clinical practice. We prospectively enrolled consecutive 554 patients with atrial fibrillation who underwent catheter ablation procedure under uninterrupted OACs. We evaluated ACT kinetics at an interval of 15 minutes during the procedure and periprocedural complications among 5 OACs (dabigatran N = 46, rivaroxaban N = 125, apixaban N = 129, edoxaban N = 184, and warfarin N = 70). Compared with the dabigatran group, time to achieve target ACT was significantly longer in the rivaroxaban and apixaban groups, but not in the edoxaban and warfarin groups (8.7 vs 11.7 minutes, P < .001; 13.3 minutes, P < .001; 8.8 minutes, P = .64; 10.3 minutes, P = .19, respectively). Heparin dose to achieve target ACT was comparable except for the warfarin group, whereas, compared with the dabigatran group, time in therapeutic range of ACT within the first hour was comparable in the rivaroxaban and apixaban group but significantly lower in the edoxaban and warfarin groups (73.7 % vs 63.0%, P = .06; 67.0 %, P = .16; 59.2 %, P = .001; 58.2%, P = .004, respectively). In multiple regression analysis, low body weight, rivaroxaban, apixaban, and morning session had significant associations with time and heparin dose to achieve target ACT, and there were positive associations of dabigatran and apixaban with time in therapeutic range of ACT within the first hour. The incidence of periprocedural complications did not significantly differ among the 5 groups. Under uninterrupted OAC use in daily clinical practice, dabigatran showed faster achievement of target ACT and higher stability of ACT than other OACs.
Despite the prognostic importance of hypoalbuminemia, the prognostic implication of a change in albumin levels has not been fully investigated during hospitalization in patients with acute ...decompensated heart failure (ADHF).
Using the data from the Kyoto Congestive Heart Failure registry on 3160 patients who were discharged alive for acute heart failure hospitalization and in whom the change in albumin levels was calculated at discharge, we evaluated the association with an increase in serum albumin levels from admission to discharge and clinical outcomes by a multivariable Cox hazard model. The primary outcome measure was a composite of all-cause death or hospitalization for heart failure.
Patients with increased albumin levels (N = 1083, 34.3%) were younger and less often had smaller body mass index and renal dysfunction than those with no increase in albumin levels (N = 2077, 65.7%). Median follow-up was 475 days with a 96% 1-year follow-up rate. Relative to the group with no increase in albumin levels, the lower risk of the increased albumin group remained significant for the primary outcome measure (hazard ratio: 0.78, 95% confidence interval: 0.69-0.90: P = 0.0004) after adjusting for confounders including baseline albumin levels. When stratified by the quartiles of baseline albumin levels, the favorable effect of increased albumin was more pronounced in the lower quartiles of albumin levels, but without a significant interaction effect (interaction P = 0.49).
Independent of baseline albumin levels, an increase in albumin during index hospitalization was associated with a lower 1-year risk for a composite of all-cause death and hospitalization in patients with acute heart failure.
