Background: Complex multi-organ interactions such as coexistence of hepato-renal dysfunction in heart failure (HF) adversely affects patient prognosis. However, the association between liver/kidney dysfunction and frailty and effects of their coexistence on HF prognosis remain unclear., Methods: This retrospective cohort study included 922 patients with HF (median age, 72 years; interquartile range: 62-79 years). All patients underwent hepato-renal function testing using the model for end-stage liver disease, excluding international normalized ratio (MELD-XI) score and frailty score. Frailty was measured using a composite of four markers: handgrip strength, gait speed, serum albumin, and activities of daily living status, combined into a total frailty score (range 0-12). Patients were assigned to a frailty score <5 (without frailty) or ≥5 (frailty) group. The multivariable logistic regression model was used to analyze the association between MELD-XI score and frailty; the prognostic value of high MELD-XI score and frailty coexistence was investigated. The endpoint was all-cause mortality., Results: After adjusting for covariates and dividing by the median MELD-XI score, the high MELD-XI score group [odds ratio: 1.663, 95 % confidence interval (CI): 1.200-2.304, p = 0.002] was significantly associated with frailty, compared with the low MELD-XI score group. One hundred and fifty deaths occurred during follow-up (median, 2.13 years; interquartile range, 0.93-4.09 years). Patients in the high MELD-XI score/frailty group had a significantly higher mortality risk, even after adjusting for HF severity (hazard ratio: 4.326, 95 % CI: 2.527-7.403, p < 0.001)., Conclusions: Hepato-renal dysfunction is associated with frailty in patients with HF, which affects patient prognosis., Brief Summary: This study showed that hepato-renal dysfunction in patients with HF, as assessed by the model for end-stage liver disease excluding international normalized ratio (MELD-XI) score, is associated with frailty, even after adjusting for factors involved in the frailty or severity of HF. Additionally, high MELD-XI score combined with frailty is associated with a poorer prognosis. These results suggest that hepato-renal dysfunction and frailty can be used for risk stratification in patients with HF., Competing Interests: Declaration of competing interest The author(s) declare no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (Copyright © 2022.

Objectives: We investigated whether SARC-F scores were associated with motor function, quality of life (QOL) related to physical function, and prognosis in older patients with cardiovascular disease (CVD) and cognitive impairment., Methods: This was a retrospective cross-sectional cohort study. The study population consisted of 408 patients with CVD (≥60 years old) who completed the SARC-F questionnaire and Mini-Cog, a cognitive function test, at discharge. Sarcopenia was defined as a total SARC-F score ≥ 4 points. Patients who were cognitively-preserved (Mini-Cog score ≥ 3 points) were excluded. Patients completed the handgrip strength, leg strength, usual gait speed, 6-minute walking distance, short physical performance battery score, and 36-item Short-Form Health Survey Physical Functioning (SF-36PF) tests before discharge. Associations of SARC-F with physical function, QOL, and prognoses (i.e., composite of all-cause death and emergency CVD rehospitalization and the number of CVD rehospitalizations) were investigated., Results: Sarcopenia (SARC-F score ≥ 4 points) was associated with poorer motor function test outcomes and SF-36PF scores (all P < 0.001). The correlations remained significant after adjusting for comorbidities (e.g., anemia, prior heart failure, and renal dysfunction). Sarcopenia was also associated with a poorer prognosis (hazard ratio: 1.574; 95 % confidence interval [CI], 1.011-2.445) and an increased risk of CVD rehospitalization (incidence rate ratio: 1.911; 95 % CI, 1.312-2.782) after adjusting for comorbidities., Conclusions and Implications: In older patients with CVD and cognitive impairment, the SARC-F questionnaire may be a simple and inexpensive tool for identifying patients with decreased motor function and a poor prognosis., Competing Interests: Conflict of interest The authors have no conflicts of interest directly relevant to the content of this article.

Objectives: To compare the Fried criteria for frailty diagnosis with the Frailty Screening Index (FSI) and the fatigue, resistance, ambulation, illness, and loss of weight (FRAIL) scale in older patients with cardiovascular disease (CVD)., Design: We conducted a retrospective 1-year follow-up cohort study of adult inpatients who participated in a cardiac rehabilitation program between June 2016 and September 2018., Setting and Participants: We included 1472 Japanese patients age 65 years and older with CVD. After excluding 765 patients with incomplete frailty measurements, 707 patients were included in the analysis., Methods: Frailty and physical function were measured before hospital discharge according to each of the 3 definitions. Outcomes were all-cause mortality and physical dysfunction., Results: The prevalence of frailty according to the Fried criteria, the FRAIL scale, and the FSI was 213 (30.1%), 181 (25.6%), and 186 (26.3%), respectively. The FSI and the FRAIL scale showed moderate agreement with the Fried criteria [vs FSI: K = 0.52, 95% confidence interval (CI): 0.45-0.59; vs FRAIL scale: K = 0.45, 95% CI: 0.37-0.52; all P < .001]. We found a significant correlation between all-cause mortality and frailty assessed by all of the definitions, even after multivariate adjustment [FSI: hazard ratio (HR): 2.43, 95% CI: 1.30-4.58, P = .006; FRAIL scale: HR: 2.32, 95% CI: 1.21-4.45, P = .011; Fried criteria: HR: 1.99, 95% CI: 1.04-3.82, P = .038). However, the prediction accuracy of the FRAIL scale was higher than that of the FSI and comparable to that of the Fried criteria for physical dysfunction., Conclusions and Implications: The FSI and the FRAIL scale showed moderate agreement with the Fried criteria regarding frailty diagnostic performance and had comparable prognostic value. However, only the FRAIL scale was as accurate as the Fried criteria in screening for physical dysfunction., (Copyright © 2022 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

Aims: Although the developmental mechanism of respiratory muscle weakness (RMW) and frailty are partly similar in patients with cardiovascular disease (CVD), their relationship remains unclear. This study aimed to investigate the correlation between RMW and frailty and its impact on clinical outcomes in patients with CVD., Methods and Results: In this retrospective observational study, consecutive 1217 patients who were hospitalized for CVD treatment were enrolled. We assessed frailty status by using the Fried criteria and respiratory muscle strength by measuring the maximal inspiratory pressure (PImax) at hospital discharge, with RMW defined as PImax <70% of the predicted value. The endpoint was a composite of all-cause death and/or readmission for heart failure. We examined the prevalence of RMW and frailty and their correlation. The relationships of RMW with the endpoint for each presence or absence of frailty were also investigated. Respiratory muscle weakness and frailty were observed in 456 (37.5%) and 295 (24.2%) patients, respectively, and 149 (12.2%) patients had both statuses. Frailty was detected as a significant indicator of RMW [odds ratio: 1.84, 95% confidence interval (CI): 1.39-2.44]. Composite events occurred in 282 patients (23.2%). Respiratory muscle weakness was independently associated with an increased incidence of events in patients with both non-frailty [hazard ratio (HR): 1.40, 95% CI: 1.04-1.88] and frailty (HR: 1.68, 95% CI: 1.07-2.63)., Conclusions: This is the first to demonstrate a correlation between RMW and frailty in patients with CVD, with 12.2% of patients showing overlap. RMW was significantly associated with an increased risk of poor outcomes in patients with CVD and frailty., Competing Interests: Conflict of interest: none declared., (Published on behalf of the European Society of Cardiology.

The use of sodium-glucose cotransporter 2 (SGLT2) inhibitors in patients with type 2 diabetes mellitus (T2DM) has been associated with decreased skeletal muscle mass but remains unclear in patients with cardiovascular disease (CVD) undergoing comprehensive outpatient cardiac rehabilitation (CR). Therefore, this study investigates the effect of SGLT2 inhibitors on the outcomes of patients with CVD and T2DM undergoing comprehensive outpatient CR. The study included 402 patients with CVD and T2DM who participated in comprehensive outpatient CR. Physical functions (grip strength, maximal quadriceps isometric strength, usual gait speed, and 6-minute walking distance) were measured at discharge as baseline and 5 months thereafter, and the association between physical functions and SGLT2 inhibitor use was reviewed. Physical functions improved regardless of SGLT2 inhibitor use. Multiple regression analysis showed that SGLT2 inhibitor use was not associated with improvement or decline in physical functions ( p ≥ 0.05). The use of SGLT2 inhibitors in patients with CVD and T2DM undergoing outpatient CR did not impair improvement in physical functions.

Although instrumental activities of daily living (IADL) are included in the outcomes of cardiac rehabilitation (CR), the relationship between IADL frequency at the end of CR and outcomes between the sexes remains unclear. We aimed to investigate the differences in frequency of IADL between the sexes and its impact on the outcomes. We retrospectively investigated 490 consecutive patients who were admitted for heart failure (HF) and participated in CR post-discharge. IADL frequency was assessed using the questionnaire-based Frenchay Activities Index (FAI). The primary endpoint was all-cause death, and the secondary endpoint was a composite of all-cause death and readmission due to HF. The cut-off values of the FAI for all-cause death in the overall cohort, females, and males were 23, 22, and 23 points, respectively. After adjusting for several factors, IADL assessed using the FAI was independently associated with all-cause mortality (hazard ratio [HR]: 0.961, 95% confidence interval [CI]: 0.937-0.986) and combined events (HR: 0.968, 95% CI: 0.952-0.985), respectively. Additionally, there was no interaction between sex and all-cause mortality. In conclusion, higher IADL frequency after CR was associated with favourable outcomes in patients with HF.

Background: The purpose of this study was to clarify the prevalence, association with frailty and exercise capacity, and prognostic implication of sarcopenic obesity in patients with heart failure., Methods: The present study included 779 older adults hospitalized with heart failure (median age: 81 years; 57.4% men). Sarcopenia was diagnosed based on the guidelines by the Asian Working Group for Sarcopenia. Obesity was defined as the percentage of body fat mass (FM) obtained by bioelectrical impedance analysis. The FM cut-off points for obesity were 38% for women and 27% for men. The primary endpoint was 1-year all-cause death. We assessed the associations of sarcopenic obesity occurrence with the short physical performance battery (SPPB) score and 6-minute walk distance (6MWD)., Results: The rates of sarcopenia and obesity were 19.3 and 26.2%, respectively. The patients were classified into the following groups: non-sarcopenia/non-obesity (58.5%), non-sarcopenia/obesity (22.2%), sarcopenia/non-obesity (15.3%), and sarcopenia/obesity (4.0%). The sarcopenia/obesity group had a lower SPPB score and shorter 6MWD, which was independent of age and sex (coefficient, - 0.120; t-value, - 3.74; P < 0.001 and coefficient, - 77.42; t-value, - 3.61; P < 0.001; respectively). Ninety-six patients died during the 1-year follow-up period. In a Cox proportional hazard analysis, sarcopenia and obesity together were an independent prognostic factor even after adjusting for a coexisting prognostic factor (non-sarcopenia/non-obesity vs. sarcopenia/obesity: hazard ratio, 2.48; 95% confidence interval, 1.22-5.04; P = 0.012)., Conclusion: Sarcopenic obesity is a risk factor for all-cause death and low physical function in older adults with heart failure., Trial Registration: University Hospital Information Network (UMIN-CTR: UMIN000023929 )., (© 2022.

Background: Usual gait speed is a prognostic factor in cardiovascular disease (CVD) patients; however, given the aging population, there has been an increase in patients with CVD with slow usual gait speed. Even among patients with slow usual gait speed, some can walk with sufficient speed during maximal gait, while others cannot. This study aimed to investigate the relationship between maximal gait speed and prognosis, and the utility of evaluating maximal gait speed in conjunction with usual gait speed in risk stratification of prognosis in patients with CVD., Methods: We included 2951 CVD patients who underwent evaluation of both usual and maximal gait speeds. They were classified into the usual (+) group [usual gait speed ≥1.0 m/s], usual (-) and maximal (+) group [usual gait speed <1.0 m/s and maximal gait speed ≥1.0 m/s], and usual (-) and maximal (-) group [usual gait speed <1.0 m/s and maximal gait speed <1.0 m/s]., Results: Slower maximal gait speed was significantly associated with higher mortality in CVD patients. This association was consistent across various subgroups. Maximal gait speed provided additional prognostic information to that of pre-existing prognostic factors and usual gait speed (P = 0.048). The usual (-) and maximal (-) group showed higher mortality (hazard ratio: 1.63; 95% confidence interval: 1.18-2.27; P = 0.003) than the usual (-) and maximal (+) group. There was no significant difference in mortality between the usual (+) group and the usual (-) and maximal (+) group., Conclusions: Maximal gait speed was an independent prognostic predictor for CVD patients. Evaluating maximal gait speed in conjunction with usual gait speed was useful for further risk stratification of prognosis in CVD patients., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Aims: Although evidence suggests that cognitive decline and physical frailty in elderly patients with heart failure (HF) are associated with prognosis, the impact of concurrent physical frailty and cognitive impairment, that is, cognitive frailty, on prognosis has yet to be fully investigated. The current study sought to investigate the prevalence and prognostic impact of cognitive frailty in elderly patients with HF., Methods and Results: This study is a sub-analysis of FRAGILE-HF, a prospective multicentre observational study involving patients aged ≥65 years hospitalized for HF. The Fried criteria and Mini-Cog were used to diagnose physical frailty and cognitive impairment, respectively. The association between cognitive frailty and the combined endpoint of mortality and HF rehospitalization within 1 year was then evaluated. Among the 1332 patients identified, 1215 who could be assessed using Mini-Cog and the Fried criteria were included in this study. Among those included, 279 patients (23.0%) had cognitive frailty. During the follow-up 1 year after discharge, 398 combined events were observed. Moreover, cognitive frailty was determined to be associated with a higher incidence of combined events (log-rank: P = 0.0146). This association was retained even after adjusting for other prognostic factors (hazard ratio: 1.55, 95% confidence interval: 1.13-2.13). Furthermore, a sensitivity analysis using grip strength, short physical performance battery, and gait speed to determine physical frailty instead of the Fried criteria showed similar results., Conclusions: This cohort study found that 23% of elderly patients with HF had cognitive frailty, which was associated with a 1.55-fold greater risk for combined events within 1 year compared with patients without cognitive frailty., (© 2022 The Authors.

Six-minute walk distance (6MWD) of 300 and 400 m are important targets of functional capacity. The present study was performed to determine cutoff values of physical function associated with 6MWD < 300 m and < 400 m in elderly patients with heart failure (HF). 6MWD, handgrip strength, quadriceps isometric strength (QIS), one-leg standing time (OLST), and 5-times sit-to-stand (5STS) before hospital discharge were evaluated in 1001 patients > 65 years (median age, 75: interquartile range, 71-80, 607 men) with HF. 6MWD < 300 and < 400 m were seen in 323 patients (32.3%) and 658 patients (65.7%), respectively. Handgrip strength, QIS, OLST, and 5STS were associated with 6MWD < 300 and < 400 m, respectively (P < 0.001). The cutoff values of handgrip strength, QIS, OLST, and 5STS were 18.9 kg, 35.0% body mass (BM), 9.1 s, and 9.5 s for 6MWD < 300 m, and 21.9 kg, 40.0% BM, 12.0 s, and 8.8 s for < 400 m, respectively. The cutoff values of physical function could be used to set cardiac rehabilitation goals and limiting determinants of reduced functional capacity in a clinical setting in elderly patients with HF., (© 2022.

Aims: A patient's understanding of his or her own comorbidities is part of the recommended patient education for those with heart failure. The accuracy of patients' understanding of their comorbidities and its prognostic impact have not been reported., Methods and Results: Patients hospitalized for heart failure (n = 1234) aged ≥65 years (mean age: 80.1 ± 7.7 years; 531 females) completed a questionnaire regarding their diagnoses of diabetes, malignancy, stroke, hypertension, chronic obstructive pulmonary disease (COPD), and coronary artery disease (CAD). The patients were categorized into three groups based on the number of agreements between self-reported comorbidities and provider-reported comorbidities: low (1-2, n = 19); fair (3-4, n = 376); and high (5-6, n = 839) agreement groups. The primary outcome was a composite of all-cause mortality or heart failure rehospitalization at 1 year. The low agreement group had more comorbidities and a higher prevalence of a history of heart failure. The agreement was good for diabetes (κ = 0.73), moderate for malignancy (κ = 0.56) and stroke (κ = 0.50), and poor-to-fair for hypertension (κ = 0.33), COPD (κ = 0.25), and CAD (κ = 0.30). The fair and low agreement groups had poorer outcomes than the good agreement group [fair agreement group: hazard ratio (HR): 1.25; 95% confidence interval (CI): 1.01-1.56; P = 0.041; low agreement group: HR: 2.74: 95% CI: 1.40-5.35; P = 0.003]., Conclusions: The ability to recognize their own comorbidities among older patients with heart failure was low. Patients with less accurate recognition of their comorbidities may be at higher risk for a composite of all-cause mortality or heart failure rehospitalization., (© 2022 The Authors.

Background: Low skeletal muscle area or density, such as myosteatosis, identified on computed tomography (CT) is associated with poor prognosis in patients with cardiovascular diseases. However, there is a lack of evidence regarding the clinical process of skeletal muscle decline as a short-term change during acute care settings. This study focused on the use of routine CT imaging for aortic disease management and investigated the changes in skeletal muscle before and after acute care., Methods: This prospective study included 123 patients who underwent abdominal CT before and after acute care. The all-abdominal and each abdominal muscle areas were divided into eight parts (e.g. rectus abdominis, psoas, and erector spine), and their areas and densities were measured at the third lumbar vertebra level after the patients were discharged and de-identified with blinding to avoid measurement bias. Short physical performance battery (SPPB) was measured at the start and end of in-hospital cardiac rehabilitation. A generalized linear model with patients as random effects was made to investigate skeletal muscle loss during acute care. Multivariate linear regression analysis was also used to assess the relationship between the change in skeletal muscle during acute care and SPPB during in-hospital cardiac rehabilitation., Results: The median age of the patients was 70 (interquartile: 58-77) years, and 69.9% (86/123) were men. The median day between acute care from the day of surgery or hospital admission and follow-up CT was 7 (interquartile: 3-8) days. Overall muscle density declined after acute care (estimate value: -3.640, 95% confidence interval [CI]: -4.538 to -2.741), and each abdominal muscle density consistently declined (interaction: F value = 0.099, P = 0.998). In contrast, there was no significant change in the overall muscle area (estimate value: -0.863, 95% CI: -2.925 to 1.200). Changes in the muscle area were different for each skeletal muscle (interaction: F value = 2.142, P = 0.037), and only the erector spine muscle significantly declined (estimate value: -1.836, 95% CI: -2.507 to -1.165). After adjusting for confounding factors, a greater decline in muscle density was associated with lower recovery score on SPPB (β = 0.296, 95% CI: 0.066 to 0.400)., Conclusions: Muscle density consistently declined after acute care, especially the erector spine muscles, which also significantly decreased in size. A higher decline in muscle density was associated with a slower recovery of physical function during in-hospital cardiac rehabilitation in patients with aortic diseases., (© 2022 The Authors.

As frailty in older patients with acute heart failure (AHF) has an adverse effect on clinical outcomes, the addition of electrical muscle stimulation (EMS) to exercise-based early rehabilitation may improve the effects of treatment. Post hoc analysis was performed on a randomized controlled study for clinical outcomes and prespecified subgroups (ACTIVE-EMS: UMIN000019551). In this trial, 31 AHF patients aged ≥ 75 years with frailty (Short Physical Performance Battery [SPPB] score 4-9) were randomized 1:1 to receive treatment with an early rehabilitation program only ( n = 16) or early rehabilitation with add-on EMS therapy ( n = 15) for 2 weeks. Changes in physical function and cognitive function between baseline and after two weeks of treatment were assessed. There were no adverse events during the EMS period. The EMS group showed significantly greater changes in quadriceps' isometric strength and SPPB compared to the control group, and EMS therapy showed uniform effects in the prespecified subgroups. There were no significant differences in the changes in other indexes of physical function and cognitive function between groups. There was no significant difference in the rate of heart failure hospitalization at 90 days between groups. In conclusion, older AHF patients with frailty showed greater improvement in lower extremity function with the addition of EMS therapy to early rehabilitation without adverse events.

It is believed that patients with acute coronary syndrome (ACS) are at an increased risk of nonalcoholic fatty liver disease (NAFLD), which can lead to sarcopenia and physical dysfunction. However, the relationship between metabolic dysfunction-associated fatty liver disease (MAFLD) and physical dysfunction and prognosis remains unclear. We investigated the prevalence of MAFLD in patients with ACS to assess the relationship between MAFLD and muscle strength, walking speed, and 6-min walking distance (6 MWD). We reviewed patients with ACS who were assessed for hepatic steatosis using the fatty liver index, and the results were further assessed to determine the presence of MAFLD. Among 479 enrolled hospitalized patients, MAFLD was identified in 234 (48.9%) patients. Multiple regression analysis revealed that MAFLD was independently associated with lower leg strength, gait speed, and 6 MWD (leg strength, p = 0.020; gait speed, p = 0.003 and 6 MWD, p = 0.011). Furthermore, in multivariate Poisson regression models after adjustment for clinical confounding factors, combined MAFLD and reduced physical functions were significantly associated with a higher incidence of clinical events. MAFLD is common in hospitalized patients with ACS and is associated with impaired physical function. Also, the coexistence of MAFLD and lower physical function predict the incidence of clinical events in patients with ACS.

Background: Exercise intolerance is widely known to be a major cardinal symptom in patients with heart failure (HF), but due to the recent coronavirus disease 2019 epidemic, it is still difficult to directly measure exercise tolerance in many hospitals and facilities. The 36-Item Short-Form Health Survey physical functioning (SF-36PF) pertain to lower extremity functioning and walking. The purpose of this study was to investigate whether SF-36PF is a useful predictor of exercise intolerance and to provide its optimal cut-off value for patients with HF., Methods and Results: SF-36PF and 6-min walking distance (6MWD) were evaluated in 372 consecutive patients with HF. Exercise intolerance was defined at 6MWD cut-offs of 200, 300, and 400 m. The addition of SF-36PF to the pre-existing determinants of exercise tolerance significantly improved the area under the curve scores (0.85 vs. 0.89, P = 0.011 for 6MWD <200 m; 0.90 vs. 0.93, P = 0.001 for 6MWD <300 m; 0.88 vs. 0.90, P = 0.021 for 6MWD <400 m) for the predictive effect on exercise intolerance. The cut-off values of SF-36PF for predicting exercise intolerance defined by 6MWD <200, 300, and 400 m were 45, 50, and 70, respectively., Conclusions: SF-36PF is a useful tool as an alternative index to predict exercise intolerance in patients with HF., (Published on behalf of the European Society of Cardiology.

Background: Although cardiac resynchronization therapy (CRT) provided functional and clinical improvement in patients with heart failure (HF) and electrical intraventricular conduction disturbances, some patients had re-worsening left ventricular (LV) function after a favorable CRT response. We analyzed the clinical variables and cardiac outcomes associated with this re-worsening LV function after CRT., Methods: In this study, 71 patients with CRT response who received CRT between 2006 and 2017 were included. CRT response was defined as a "≥ 10% improvement in LV ejection fraction (LVEF) on follow-up." Patients were classified into two groups: (i) persistent: (n = 48, 68%), defined as those with a CRT response and (ii) re-worsening: (n = 23, 32%), consisting of those who fell out of the definition of a CRT response after an initial CRT response., Results: Half of the patients in the re-worsening group failed to maintain a CRT response from two years upwards. A longer duration from HF diagnosis to CRT implantation, nonspecific intraventricular conduction delay (NIVCD) on electrocardiogram at CRT implantation, and a lower increased LVEF at initial CRT response were independent predictors for the re-worsening group. Patients in the re-worsening group had a higher incidence rate for HF hospitalization and cardiac deaths, compared with those in the persistent group., Conclusion: One-third of CRT responders experienced re-worsening LVEF, which was associated with poor outcomes. CRT responders with NIVCD, longer HF duration, and a lower increased LVEF at initial CRT response should be monitored with caution., (Copyright © 2021. Published by Elsevier Ltd.)

Aims: To investigate the impact of baseline kidney function on outcomes following comprehensive cardiac rehabilitation (CR) in patients with heart failure (HF)., Methods: We reviewed a total of 3,727 patients who were admitted for HF treatment. Estimated glomerular filtration rate (eGFR), quadriceps strength (QS), and 6-min walk distance (6MWD) were measured at hospital discharge as a baseline and 5 months thereafter in participants of outpatient comprehensive CR. The association between outpatient CR participation and all-cause events was evaluated using propensity score-matched analysis in subgroups across eGFR stages. The changes in QS and 6MWD following 5-month CR were compared between eGFR stages., Results: Out of the studied patients, 1585 (42.5%) participated in outpatient CR. After propensity matching for clinical confounders, 2680 patients were included for analysis (pairs of n = 1340 outpatient CR participants and nonparticipants). The participation in outpatient CR was significantly associated with low clinical events in subgroups of eGFR ≥ 60 [hazard ratio (HR): 0.65, 95% confidence interval (CI): 0.51-0.84] and eGFR 45-60 (HR: 0.71, 95% CI: 0.55-0.92), but not in eGFR 30-45 (HR: 0.83, 95% CI: 0.64-1.08) and eGFR < 30 (HR: 0.88, 95% CI: 0.69-1.12). QS and 6MWD were significantly higher after 5-month CR than those at baseline (P < 0.001, respectively), but lower baseline eGFR correlated with lower changes in QS and 6MWD (trend P < 0.001, respectively)., Conclusions: Although low baseline kidney function attenuates the outcomes of CR, outpatient CR seems to be associated with a better prognosis and positive change in physical function in HF patients with low kidney function., (© 2021.

Background: No reports explicitly examined the relationship between work defined as a certain type of social participation or role and the protective effect on the prognosis of patients with heart failure (HF) by preventing frailty. Therefore, this study examined whether social participation through work before admission relates to future adverse events in HF patients aged ≥65 years, and whether each frailty domain mediates the association between work and prognosis as a second analysis of a multi-centered prospective study (FRAGILE-HF study)., Methods: We retrospectively reviewed 1,332 older patients with HF whose work status before admission to the hospital were investigated. We assessed the physical, cognitive, and social domains of frailty and performed causal mediation analysis to examine the mediating relationship of each frail domain between work status before admission and 1-year combined events (HF-related readmission and all-cause death)., Results: The subjects' median age was 81 years, and 56.9% (758/1,332) were male. Among the three domains of frailty, work before admission reduced only social frailty after adjusting for confounding factors (odds ratio: 0.505, 95% confidence interval: 0.364-0.701). Patients with work before admission had a significantly better prognosis (hazard ratio: 0.720, 95% confidence interval: 0.523-0.989). Only social frailty partly mediated the relationship between work status and combined events (p <0.05)., Conclusions: Work status before admission is associated with 1-year combined events, in part through social frailty., (Copyright © 2021.

Although postural hypotension (PH) is reportedly associated with mortality in the general population, the prognostic value for heart failure is unclear. This was a post-hoc analysis of FRAGILE-HF, a prospective multicenter observational study focusing on frailty in elderly patients with heart failure. Overall, 730 patients aged ≥ 65 years who were hospitalized with heart failure were enrolled. PH was defined by evaluating seated PH, and was defined as a fall of ≥ 20 mmHg in systolic and/or ≥ 10 mmHg in diastolic blood pressure within 3 min after transition from a supine to sitting position. The study endpoints were all-cause death and heart failure readmission at 1 year. Predictive variables for the presence of PH were also evaluated. PH was observed in 160 patients (21.9%). Patients with PH were more likely than those without PH to be male with a New York Heart Association classification of III/IV. Logistic regression analysis showed that male sex, severe heart failure symptoms, and lack of administration of angiotensin-converting enzyme inhibitors were independently associated with PH. PH was not associated with 1-year mortality, but was associated with a lower incidence of readmission after discharge after adjustment for other covariates. In conclusion, PH was associated with reduced risk of heart failure readmission but not with 1-year mortality in older patients with heart failure., (© 2022. The Author(s).)

Background and Aims: Frailty and sarcopenia are common and confer poor prognosis in elderly patients with heart failure; however, gender differences in its prevalence or prognostic impact remain unclear., Methods and Results: We included 1332 patients aged ≥65 years, who were hospitalized for heart failure. Frailty and sarcopenia were defined using the Fried phenotype model and Asian Working Group for Sarcopenia criteria, respectively. Gender differences in frailty and sarcopenia, and interactions between sex and prognostic impact of frailty/sarcopenia on 1-year mortality were evaluated. Overall, 53.9% men and 61.0% women and 23.7% men and 14.0% women had frailty and sarcopenia, respectively. Although sarcopenia was more prevalent in men, no gender differences existed in frailty after adjusting for age. On Kaplan-Meier analysis, frailty and sarcopenia were significantly associated with 1-year mortality in both sexes. On Cox proportional hazard analysis, frailty was associated with 1-year mortality only in men, after adjusting for confounding factors (hazard ratio [HR], 1.94; 95% confidence interval [CI], 1.19-3.16; P = 0.008 for men; HR, 1.63; 95% CI, 0.84-3.13; P = 0.147 for women); sarcopenia was an independent prognostic factor in both sexes (HR, 1.93; 95% CI, 1.13-3.31; P = 0.017 for men; HR, 3.18; 95% CI, 1.59-5.64; P = 0.001 for women). There were no interactions between sex and prognostic impact of frailty/sarcopenia (P = 0.806 for frailty; P = 0.254 for sarcopenia)., Conclusions: Frailty and sarcopenia negatively affect older patients with heart failure from both sexes., Clinical Trials: This study was registered at the University Hospital Information Network (UMIN-CTR, unique identifier: UMIN000023929) before the first patient was enrolled., Competing Interests: Declaration of competing interest Dr. Yuya Matsue and Takatoshi Kasai are affiliated with a department endowed by Philips Respironics, ResMed, Teijin Home Healthcare, and Fukuda Denshi; Dr. Yuya Matsue received an honorarium from Otsuka Pharmaceutical Co and Novartis Japan.

Background: Difficulty in activities of daily living (ADL) is common in patients with cardiovascular disease (CVD) and is associated with mortality., Objectives: The relationship between gait speed/6-minute walking distance (6MWD) and difficulties in ADL in patients with CVD was explored., Methods: The study population consisted of 447 patients with CVD for whom data on gait speed, 6MWD, and difficulty in ADL during outpatient rehabilitation were available. Relationships of gait speed/6MWD and difficulty in ADL were examined using propensity-adjusted logistic regression analysis., Results: Both gait speed and 6MWD were significantly related to difficulty in ADL, and the areas under the curves were large. The cutoff values ranged from 0.93 to 1.30 m/s for gait speed and 370 to 500 m for 6MWD, from basic ADL to vigorous activities., Conclusions: Both gait speed and 6MWD were used for the estimation of difficulty in ADL in patients with CVD. Gait speed can be measured easily and therefore could be incorporated in busy clinical practice to identify patients at risk for functional decline., Competing Interests: Declaration of Competing Interest The authors have no conflict of interest to disclose., (Copyright © 2021 Elsevier Inc.

Background: Low physical performance may contribute to reduced exercise capacity in older patients with heart failure (HF). We sought to identify the determinants of exercise capacity out of a plethora of background factors, including measures of physical performance., Methods: We performed a post-hoc analysis of a cohort study that included 1205 consecutive older (age ≥ 65 years) hospitalized patients (the median age, 80 years; 57.4% males)., Results: Low physical performance, defined as ≤1.0 m/s for gait speed, ≥12 s for the 5-time chair stand test, or ≤ 9 points for the Short Physical Performance Battery in both sexes, was seen in 83.9% of the cohort. Multivariate regression analysis revealed that each parameter of physical performance (i.e., gait speed, chair stand test, and balance test) was identified as an independent determinant of lower exercise capacity assessed using the 6-min walking distance. In a logistic regression model, low physical performance predicted short (<300 m) 6-min walking distance (adjusted odds ratio 10.28, 95% CI 6.01-17.60, p < 0.001). No interaction was detected between patients with preserved and reduced ejection fraction., Conclusions: Low physical performance was prevalent and independently associated with exercise capacity in older patients with HF, irrespective of preserved or reduced ejection fraction., (Copyright © 2021 Elsevier Inc.

Aims: High-sensitivity cardiac troponin T (hs-cTnT) and B-type natriuretic peptide (BNP) are associated with prognosis and severity in patients with heart failure (HF); however, their association with physical function is unclear. This study aimed to investigate whether hs-cTnT and BNP levels are associated with physical function in patients with HF., Methods and Results: Hs-cTnT, BNP, and physical function (maximal quadriceps isometric strength [QIS], usual gait speed, and 6-min walk distance [6MWD]) were evaluated in 363 consecutive patients with HF (median age, 70 [60-78] years). Patients were divided into four groups according to their median hs-cTnT and BNP levels. After adjusting for demographic characteristics, laboratory levels, and HF severity, higher hs-cTnT and BNP levels were significantly associated with lower physical function (log hs-cTnT, β = -0.162, P = 0.001, for maximal QIS; β = -0.175, P = 0.002, for usual gait speed, and β = -0.129, P = 0.004, for 6MWD; log BNP, β = -0.090, P = 0.092, for maximal QIS, β = 0.038, P = 0.516, for usual gait speed, and β = -0.108, P = 0.023, for 6MWD). In addition, the high hs-cTnT and high BNP group had significantly lower physical function (all P < 0.05) than the low hs-cTnT and low BNP group., Conclusions: Higher hs-cTnT and BNP levels are both associated with lower physical function in patients with HF, but hs-cTnT levels showed a more consistent association. The combination of hs-cTnT and BNP may be effective for the stratification of physical function in patients with HF., (© 2021 The Authors.

Background: Although the coexistence of heart failure (HF) with atrial fibrillation (AF) exhibits poor outcomes, the correlation between AF status and outcomes after exercise-based cardiac rehabilitation (CR) remains unclear in older individuals with HF., Objective: This retrospective study aimed to investigate the impact of AF on changes in physical function and prognosis after CR in older individuals with HF., Methods: We enrolled consecutive individuals with HF who were ≥ 60 years old who received 5-month CR. Exercise-based CR involved moderate-intensity aerobic exercises tailored to each participant. Isometric quadriceps strength (QS) and 6-min walk distance (6MWD) were measured as physical function, at baseline and 5 months thereafter. We compared QS and 6MWD changes from baseline to the 5-month observation period (QS and 6MWD) between sinus rhythm and AF. We examined composite incidence of all-cause death or unplanned readmission after 5-month CR and analysed the association of QS and 6MWD with clinical events, estimating adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs)., Results: Of the 764 participants, 476 (62%) had sinus rhythm, and 288 (38%) had AF. AF was associated with lower QS and 6MWD at baseline. The 2 groups did not differ in QS and 6MWD after adjusting for clinical confounders. With sinus rhythm, greater change in QS and 6MWD was significantly associated with reduced incidence of clinical events (QS tertile: aHR 0.75 [95% CI 0.60-0.92]; 6MWD tertile: aHR 0.59 [95% CI 0.46-0.76]); however, with AF, this association was observed for only 6MWD and not QS (QS: aHR 0.92 [95% CI 0.72-1.17]; 6MWD: aHR 0.73 [95% CI 0.54-0.98])., Conclusion: AF in older individuals with HF is associated with reduced physical function at baseline but not response to exercise-based CR. Furthermore, positive response of physical function after CR is associated with better prognosis regardless of AF, which suggests that exercise-based CR is potentially effective in older individuals with HF and AF., (Copyright © 2020 Elsevier Masson SAS.

Aims: Although aging is strongly associated with both heart failure and a decline in gait speed, a definition of slowness incorporating an age-related decline has yet to be developed. We aimed to define an event-driven cut-off for the relative decline in gait speed against age-adjusted reference values derived from the general population and evaluate its prognostic implications., Methods and Results: Standardized gait speed (SGS) was defined as the median gait speed stratified by age, sex, and height in 3777 elderly (age ≥ 65 years) individuals without a history of cardiovascular diseases (Tokyo Metropolitan Institute of Gerontology-Longitudinal Interdisciplinary Study on Aging: general population cohort). The mortality event-driven optimal cut-off of the SGS ratio (actual gait speed divided by the respective SGS) was defined using FRAGILE-HF cohort data and externally validated using Kitasato cohort data, comprising 1301 and 1247 hospitalized elderly patients with heart failure, respectively. Using FRAGILE-HF data, the optimal SGS ratio cut-off was determined as 0.527. In the Kitasato cohort, SGS ratio < 0.527 was associated with a higher 1 year [hazard ratio (HR): 1.70, 95% confidence interval (CI): 1.07-2.72, P = 0.024] and long-term (HR: 1.46, 95% CI: 1.05-2.02, P = 0.024) mortality rate, independent of pre-existing covariates., Conclusions: Gait speed was significantly declined in patients with heart failure, even after taking age and sex-related decline into account. A SGS ratio of 0.527 is a validated cut-off for slowness independently associated with mortality in patients with heart failure age ≥65., (© 2021 The Authors.

Aims: Intestinal oedema is one of the manifestations associated with right-sided heart failure (HF), which is known to be associated with poorer patient outcomes. We attempted to reveal the association between intestinal oedema and diuretic resistance in hospitalized patients with acute HF., Methods and Results: Among 213 hospitalized patients with acute HF, abdominal ultrasonography was performed under clinically stable conditions after initial HF treatments. The association among abdominal ultrasonographic parameters, maintenance doses of loop diuretics, and responsiveness to initial loop diuretic treatment was evaluated. Higher mean colon wall thickness (CWT) independently correlated with a higher dose of loop diuretics at enrolment (adjusted β = 0.198, P = 0.0004). Increased mean CWT also correlated with poor response to oral loop diuretics as an initial treatment, whereas it did not correlate with the response to intravenous loop diuretics. Discrimination of non-responders to initial oral loop diuretics resulted in a sensitivity of 0.772 and a specificity of 0.733 using a mean CWT cut-off value of ≥3 mm., Conclusions: In hospitalized patients with acute HF, a strong correlation was identified among the severity of intestinal oedema, required quantities as maintenance loop diuretic doses, and poor responsiveness to oral loop diuretics at admission., (© 2021 The Authors.

Background Frailty is conceptualized as an accumulation of deficits in multiple areas and is strongly associated with the prognosis of heart failure (HF). However, the social domain of frailty is less well investigated. We prospectively evaluated the clinical characteristics and prognostic impact of social frailty (SF) in elderly patients with HF. Methods and Results FRAGILE-HF (prevalence and prognostic value of physical and social frailty in geriatric patients hospitalized for heart failure) is a multicenter, prospective cohort study focusing on patients hospitalized for HF and aged ≥65 years. We defined SF by Makizako's 5 items, which have been validated as associated with future disability. The primary end point was a composite of all-cause death and rehospitalization because of HF. The impact of SF on all-cause mortality alone was also evaluated. Among 1240 enrolled patients, 825 (66.5%) had SF. During the 1-year observation period after discharge, the rates of the combined end point and all-cause mortality were significantly higher in patients with SF than in those without SF (Log-rank test: both P  < 0.05). SF remained as significantly associated with both the combined end point (hazard ratio, 1.30; 95% CI, 1.02-1.66; P  = 0.038) and all-cause mortality (hazard ratio, 1.53; 95% CI, 1.01-2.30; P  = 0.044), even after adjusting for key clinical risk factors. Furthermore, SF showed significant incremental prognostic value over known risk factors for both the combined end point (net-reclassification improvement: 0.189, 95% CI, 0.063-0.316, P  = 0.003) and all-cause mortality (net-reclassification improvement: 0.234, 95% CI, 0.073-0.395, P  = 0.004). Conclusions Among hospitalized geriatric patients with HF, two thirds have SF. Evaluating SF provides additive prognostic information in elderly patients with HF.

Objective: This study investigated the incidence and risk factors of postoperative delirium (POD) after transcatheter aortic valve replacement (TAVR) and to evaluate the association between preoperative conditions, particularly frailty, and POD., Design: Observational, case-control study., Setting: Single-center university hospital., Participants: The study comprised 124 patients who underwent TAVR and were divided into the following two groups: group D (patients diagnosed with POD) and group C (patients without POD)., Interventions: None., Measurements and Main Results: Twenty-seven patients (21.7%) developed POD (95% confidence interval 14.9%-30.1%). POD was defined as a diagnosis of delirium using the Confusion Assessment Method for Intensive Care Unit scale during the patients' intensive care unit stay. Preoperative and postoperative data of patient characteristics were obtained from their medical records. A multivariate logistic regression analysis was performed using variables associated with POD incidence. Frailty scores were significantly higher in group D than in group C. The distance covered in the six-minute walk test (6MD) was significantly shorter in group D than in group C. The risk of developing POD was significantly higher in patients with a 6MD shorter than 220 m. Multivariate logistic regression analysis showed that a shorter 6MD was an independent risk factor for POD (odds ratio 5.66; p = 0.004)., Conclusion: In the present study, POD was seen in 21.7% of the patients who underwent TAVR. A 6MD shorter than 220 m was an independent preoperative risk factor for POD. For patients at high risk of POD, more careful management in the perioperative period may reduce POD., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Aims: Sarcopenia, one of the extracardiac factors for reduced functional capacity and poor outcome in heart failure (HF), may act differently between HF with preserved ejection fraction (HFpEF) and HF with reduced ejection fraction (HFrEF). We sought to investigate the impact of sarcopenia on mortality in HFpEF and HFrEF., Methods and Results: We performed a post hoc analysis of a multicentre prospective cohort study, including 942 consecutive older (age ≥65 years) hospitalized patients: 475 with HFpEF (ejection fraction ≥45%, age 81 ± 7 years, 48.8% men) and 467 with HFrEF (ejection fraction <45%, age 78 ± 8 years, 68.1% men). Sarcopenia was diagnosed according to the international criteria incorporating muscle strength (handgrip strength), physical performance (gait speed), and skeletal muscle mass (appendicular skeletal mass). The HFpEF group consisted of fewer patients with low appendicular skeletal muscle mass index measured using bioelectrical impedance analysis [<7.0 kg/m2 (men) and <5.7 (women); 22.1% vs. 31.0%, P = 0.003], and more patients with low handgrip strength [<26 kg (men) and <18 (women); 67.8% vs. 55.5%, P < 0.001], and slow gait speed [<0.8 m/s (both sexes); 54.5% vs. 41.1%, P < 0.001] than the HFrEF group, resulting in a similar sarcopenia prevalence in the two groups (18.1% vs. 21.6%, P = 0.191). Sarcopenia was an independent predictor of 1-year mortality in both HFpEF and HFrEF [hazard ratio (95% confidence interval) 2.42 (1.36-4.32), P = 0.003 in HFpEF and 2.02 (1.08-3.75), P = 0.027 in HFrEF; P for interaction = 0.666] after adjustment for other predictors., Conclusions: In older patients with HF, sarcopenia contributes to mortality similarly in HFpEF and HFrEF., (Published on behalf of the European Society of Cardiology.

Background: Patients with non-ischemic dilated cardiomyopathy (DCM) often show ischemia-like electrocardiographic findings. We aimed to elucidate the clinical impact of ischemia-like electrocardiographic findings in DCM, focusing on left ventricular reverse remodeling (LVRR)., Methods: We evaluated 195 patients hospitalized with heart failure (HF) and diagnosed with DCM. All patients underwent twelve-lead electrocardiography (ECG) and echocardiography during hospitalization and at the 2-year follow-up., Results: During hospitalization, 152 (78%) patients experienced ischemia-like ECG findings (Minnesota codes I3, IV1-3, V1-3, or VII1); 43 patients (22%, non-ischemia-like group) did not experience these findings. Ischemia-like ECG findings were normalized during hospitalization in 64 patients (33%, transient-ischemia-like group) but were unchanged in 88 patients (45%, persistent-ischemia-like group). The highest rates of LVRR, defined as an increase in LV ejection fraction from ≥10% to a final value of ≥35%, along with decreased LV end-diastolic dimension of ≥10% during 2 years of follow-up, were shown in the transient-ischemia-like group (transient-ischemia-like group, 91%; persistent-ischemia-like group, 40%; non-ischemia-like-group, 51%; p < 0.001). The transient-ischemia-like group had lowest composite event rates, including readmission for HF, the detection of major ventricular arrhythmia, and sudden cardiac death., Conclusions: Normalization of ischemia-like ECG findings during the first HF treatments was associated with a higher occurrence of mid-term LVRR and favorable long-term outcome in patients with DCM., (Copyright © 2021.

Objectives: We investigated whether the FRAIL scale questionnaire is consistent with the Fried criteria, predicts all-cause mortality, and reflects physical dysfunction in patients with heart failure (HF)., Design: Secondary analysis of FRAGILE-HF, a cohort study that enrolled participants from 2016 to 2018 and followed-up for 1-year of discharge., Setting and Participants: A prospective multicenter cohort study in which 15 hospitals in Japan (8 university hospitals and 7 nonuniversity teaching hospitals) participated. We prospectively enrolled 1332 consecutive hospitalized patients ≥65 years old with HF and analyzed 1028 patients after excluding 304 patients with missing data on the FRAIL scale., Methods: The FRAIL scale, the Fried model, and physical function were measured before discharge. The endpoint was all-cause mortality., Results: According to the FRAIL scale, 459 (44.6%) and 491 (47.8%) were classified as frail and prefrail, respectively. The Kappa coefficient between the FRAIL scale and the Fried criteria were 0.39 [95% confidence interval (CI) 0.34-0.44; P < .001]. The area under the receiver-operating characteristic curves for frailty diagnosed by the Fried criteria of the FRAIL scale was 0.74 (95% CI 0.71-0.76; P < .001). A total of 118 deaths occurred during 1 year of follow-up. After adjusting for the MAGGIC risk score and log-BNP, The FRAIL scale predicted all-cause mortality (hazard ratio 1.17; 95% CI 1.01-1.36; P = .035). The FRAIL scale was also associated with various physical dysfunctions that correlated with poor prognosis., Conclusions and Implications: The FRAIL scale had moderate consistency with the Fried criteria, predicted all-cause mortality, and reflected clinically important physical dysfunctions., (Copyright © 2021 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

Aims: Functional decline due to skeletal muscle abnormalities leads to poor outcomes in patients with acute heart failure (AHF). The 6-minute walking test (6MWT) reliably evaluates functional capacity, but its technical difficulty for the elderly often limits its benefits. Although the Short Physical Performance Battery (SPPB) is a comprehensive measure of physical performance, its role in AHF remains unclear. This study aimed to examine the prognostic significance of SPPB compared to the 6MWT in elderly patients hospitalized for AHF., Methods and Results: We retrospectively analysed 1192 elderly patients with AHF whose SPPB and 6MWT were measured during the hospitalization. The primary outcome measure was defined as a composite of all-cause death and heart failure readmission until 1 year after discharge. Patients with lower SPPB scores (0-6, n = 373) had significantly poorer outcomes than those with higher SPPB scores (7-12, n = 819) even after multivariable adjustment [adjusted hazard ratio (HR) 1.28, 95% confidence interval (CI) 1.01-1.61; P = 0.049], similar to those with shorter 6MWT (

Background: Although oxygen uptake (VO 2 ) during exercise stress is a surrogate marker for prognosis in patients with cardiovascular disease (CVD), the stress test is sometimes difficult to perform owing to patient conditions, such as ageing or comorbidities. We investigated the relationships between VO 2 during usual gait with physical function and prognosis in patients with CVD., Methods: This single-centre observational study enrolled consecutive patients who were hospitalized for CVD treatment. Isometric quadriceps strength (QS) and 6-min walk distance (6MWD) as physical functions, and VO 2 during usual gait speed were measured at hospital discharge. We assessed the changes in VO 2 per body weight between at rest and during gait divided by gait speed (VO 2 /kg/gait) and analysed the relationships of VO 2 /kg/gait with physical functions and composite incidences of all-cause death or unplanned readmission after discharge., Results: In 367 patients (age, 65 ± 13 years; females, 34%), 112 clinical events occurred. VO 2 /kg/gait showed significant negative correlations to QS (β = -0.114, p = 0.024) and 6MWD (β = -0.163, p < 0.001) after adjusting for confounding factors. High VO 2 /kg/gait was significantly associated with a high rate of clinical events (hazard ratio for 1 standard deviation of VO 2 /kg/gait, 1.36; 95% confidence interval, 1.11-1.66). This association was also observed in subgroups of older age and frailty., Conclusions: High VO 2 during usual gait was a relevant factor for low physical function and poor prognosis in patients with CVD and even in older age and frailty, meaning that VO 2 during usual gait might be a novel and useful marker in clinical practice., (Copyright © 2021 Elsevier B.V.

Clinical parameters with correlation to diuretic effects after initiation of sodium-glucose cotransporter-2 (SGLT2) inhibitors are unclear. We aimed to identify the factors associated with the diuretic effect observed following the initiation of SGLT2 inhibitors in patients with diabetes having an acute heart failure (HF). Fifty-six patients included were hospitalized for acute HF with diabetes and started on SGLT2 inhibitors. Changes in urine volume (ΔUV) and blood/urine laboratory parameters before and during the first 4 days of therapy were evaluated. Data were prospectively obtained under clinically stable conditions after initial HF treatment. UV increased following the initiation of SGLT2 inhibitors [UV at baseline (BL): 1383 ± 479 mL/day; ΔUV over 4 days: + 189 ± 358 mL/day]. Multivariate analysis revealed no association between BL-hemoglobin A1c or BL-estimated glomerular filtration rate and ΔUV. Conversely, higher BL-fasting plasma glucose (FPG) and higher BL-urine N-acetyl-β-D-glucosaminidase (NAG) were associated with a higher ΔUV. ΔUV was inversely associated with ΔFPG and ΔNAG, and positively associated with Δurinary sodium excretion. Elevated FPG and NAG both improved over 4 days of treatment. In conclusion, the diuretic effect of SGLT2 inhibitors was glycemia-dependent, and was associated with a reduction in elevated renal-tubular markers in hospitalized HF complicated with diabetes.

Background and Aims: Although muscle dysfunctions are widely known as a poor prognostic factor in patients with cardiovascular disease, no study has examined whether the addition of low skeletal muscle density (SMD) assessed by computed tomography (CT) to muscle dysfunctions is useful. This study examined whether SMDs can strengthen the predictive ability of muscle dysfunctions for adverse events in patients who underwent cardiovascular surgery., Methods and Results: We retrospectively reviewed 853 patients aged ≥40 years who had preoperative CT for risk management purposes and who measured muscle dysfunctions (weakness: low grip strength and slowness: slow gait speed). Low SMD based on transverse abdominal CT images was defined as a mean Hounsfield unit of the psoas muscle <45. All definitions of muscle dysfunction (weakness only, slowness only, weakness or slowness, weakness and slowness), the addition of SMDs was shown to significantly improve the continuous net reclassification improvement and integrated discrimination improvement for adverse events in all analyses (p < 0.05). Low SMDs combined with each definition of muscle dysfunction had the highest risk of all-cause death (hazard ratio: lowest 3.666 to highest 6.002), and patients with neither low SMDs nor muscle dysfunction had the lowest risk of all-cause and cardiovascular-related events., Conclusion: The addition of SMDs consistently increased the predictive ability of muscle dysfunctions for adverse events. Our results suggest that when CT is performed for any clinical investigation, the addition of the organic assessment of skeletal muscle can strengthen the diagnostic accuracy of muscle wasting., Competing Interests: Declaration of competing interest The authors have no conflict of interests to declare., (Copyright © 2021 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.

Frailty is a common comorbidity associated with adverse events in patients with heart failure, and early recognition is key to improving its management. We hypothesized that the AST to ALT ratio (AAR) could be a marker of frailty in patients with heart failure. Data from the FRAGILE-HF study were analyzed. A total of 1327 patients aged ≥ 65 years hospitalized with heart failure were categorized into three groups based on their AAR at discharge: low AAR (AAR < 1.16, n = 434); middle AAR (1.16 ≤ AAR < 1.70, n = 487); high AAR (AAR ≥ 1.70, n = 406). The primary endpoint was one-year mortality. The association between AAR and physical function was also assessed. High AAR was associated with lower short physical performance battery and shorter 6-min walk distance, and these associations were independent of age and sex. Logistic regression analysis revealed that high AAR was an independent marker of physical frailty after adjustment for age, sex and body mass index. During follow-up, all-cause death occurred in 161 patients. After adjusting for confounding factors, high AAR was associated with all-cause death (low AAR vs. high AAR, hazard ratio: 1.57, 95% confidence interval, 1.02-2.42; P = 0.040). In conclusion, AAR is a marker of frailty and prognostic for all-cause mortality in older patients with heart failure.

Background & Aims: Although the Global Leadership Initiative on Malnutrition (GLIM) proposed a consensus scheme for diagnosing malnutrition in adults in clinical settings globally, the prevalence and prognostic value of malnutrition defined by GLIM criteria have yet to be evaluated in elderly patients with heart failure. This study aimed to determine the prevalence and prognostic implication of malnutrition as defined by GLIM criteria in comparison to those for a pre-existing definition of malnutrition, the geriatric nutritional risk index (GNRI), in elderly patients with heart failure METHODS: We evaluated malnutrition by two metrics, the GLIM criteria and geriatric nutritional risk index (GNRI), in 890 hospitalized patients with decompensation of heart failure aged ≥65 years, able to ambulate at discharge. The primary outcome was all-cause death within 1 year of discharge., Results: According to GLIM criteria and GNRI <92, 42.4% and 46.5% of participants, respectively, had malnutrition, with moderate agreement (Cohen's kappa coefficient: 0.46 [95% confidence interval: 0.40-0.51]). During 1 year of follow-up, 101 (11.4%) deaths were observed, and malnutrition defined by either the GLIM criteria or GNRI was associated with a higher mortality rate, independent of other prognostic factors (GNRI: hazard ratio, 1.45, P = 0.031; GLIM: hazard ratio, 1.57, P = 0.016). Although malnutrition defined by either criterion showed additive prognostic value when added to a model incorporating pre-existing prognostic factors, defining malnutrition by GLIM criteria instead of the GNRI yielded a statistically significant improvement in model prognostic predictive ability (net-reclassification improvement, 0.44, P < 0.001; integrated discrimination index, 0.013, P < 0.001)., Conclusions: In elderly patients with heart failure, 42.4% are malnourished according to the GLIM criteria, which is associated with a poor prognosis, independent of known prognostic factors., Clinical Trial Registration: University Hospital Medical Information Network (UMIN-CTR, https://www.umin.ac.jp/ctr/index.htm, study unique identifier: UMIN000023929)., Competing Interests: Conflict of interest Mr. Susumu Hirose is an employee of Pfizer, Inc.

The Impella 5.0 is a catheter-mounted left ventricular assist device that is inserted through the patient's subclavian artery. This device allows patient mobilization. Early mobility improves outcomes, including physical function and exercise tolerance, in critically ill patients and those with heart failure (HF). However, there have been no studies regarding the safety of early mobilization during the period of Impella 5.0 insertion based on hemodynamic assessment.A 39-year-old man with idiopathic dilated cardiomyopathy and cardiogenic shock was transferred to our hospital for Impella 5.0 insertion. We started neuromuscular electrical stimulation (NMES) and mobilization eight days after Impella 5.0 insertion. The safety of NMES and mobilization was assessed based on mean blood pressure, heart rate (HR), and mean pulmonary artery pressure measurements as hemodynamic indicators. Muscle strength was also assessed using the Medical Research Council (MRC) scale. Throughout the interventions, only the HR increased slightly during mobilization, and there were no hemodynamic abnormalities. Also, the MRC scale score improved as mobilization progressed. The results presented here suggest that NMES and mobilization are safe and feasible in patients with Impella 5.0 insertion, and therefore should be widely adopted.

Background: Dynapenia, defined as age-associated loss of skeletal muscle strength, is associated with increased mortality rate, poor activities of daily living, and reduced quality of life. Therefore, dynapenia appears to be a better independent predictor of mortality than sarcopenia in the elderly. However, the prognostic utility of dynapenia in patients with cardiovascular disease (CVD) is not clear. This study was performed to examine the prognostic utility of dynapenia defined by the criteria of Manini et al. in patients with CVD., Methods: The findings of 4192 consecutive patients ≥30 years old (median [interquartile range (IQR)] age 69 [60-76] years, 2874 males) with CVD were reviewed. Grip strength and quadriceps isometric strength (QIS) were measured just before hospital discharge, and low grip strength (<26 kg in males and <18 kg in females), low QIS (<45.0% body mass [BM] and <35.0% BM in males and females, respectively) were considered to indicate dynapenia. The endpoint was all-cause mortality., Results: A total of 507 deaths occurred during follow-up (median 2.0 years, IQR 0.8-4.4 years). The overall prevalence of dynapenia was 33.6% and increased with age (p for trend < 0.01). Females showed a significantly higher prevalence rate of dynapenia than males (43.3% vs. 29.2%, respectively; p < 0.01). Patients with dynapenia showed higher all-cause mortality rate than non-dynapenia patients (adjusted hazard ratio: 1.84; 95% confidence interval: 1.51-2.23; p < 0.01)., Conclusions: Dynapenia has a high prevalence among patients with CVD and is associated with increased mortality rate., Competing Interests: Conflict of interest The authors declare there are no potential conflicts of interest with respect to the research, authorship and/or publication of this article., (Copyright © 2020 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Introduction: The post-intensive care syndrome (PICS) encompasses multiple, diverse conditions, such as physical disability, cognitive impairment, and depression. We sought to evaluate whether conditions within PICS have similar associations with mortality among survivors of critical illness., Materials and Methods: In this retrospective cohort study, we identified 248 critically ill patients with intensive care unit stay ≥72 hours, who underwent PICS evaluation. Patients with disability in activities of daily living, cognitive impairment, or depression before hospitalization were excluded. We defined PICS using established measures of physical disability (usual gait speed), cognitive impairment (Mini-Cog test), and depression (Patient Health Questionnaire-2) at hospital discharge. The endpoint was all-cause mortality., Results: Patients had a median age of 69 years and Acute Physiology and Chronic Health Evaluation (APACHE) II score of 16. One hundred thirty-two patients were classified as having PICS, and 19 patients died. 81/248 (34%) patients had physical disability, 42/248 (19%) had cognitive impairment, and 44/248 (23%) had depression. After adjusting for covariates on multivariable Cox regression analyses, PICS was significantly associated with all-cause mortality (hazard ratio [HR] 3.78, 95% confidence interval [CI] 1.02 - 13.95; P = 0.046). However, the association between PICS and all-cause mortality was related to physical disability and cognitive impairment (P = 0.001 and P = 0.027, respectively), while depression was not (P = 0.623)., Conclusion: While PICS as a syndrome has been useful in gaining attention to the sequelae of critical illness, its relationship with long-term mortality is driven largely by physical disability and cognitive impairment and not depression., Competing Interests: The authors have declared that no competing interests exist.

Background: This study was performed to test the hypothesis that low quadriceps isometric strength (QIS) is associated with greater risk of mortality and has the additive prognostic significance to the severity of heart failure (HF) and gait speed in older patients with HF., Methods: A retrospective cohort study was performed in 1273 patients ≥ 60 years of age with HF (mean age 75 ± 8 years, 59.1% men); all of whom were evaluated during hospitalization for usual gait speed and maximal QIS. The QIS was expressed relative to body mass (% BM). The endpoint was all-cause mortality., Results: Over a median follow-up period of 1.59 years (interquartile range, 0.58 to 3.42 years), 224 patients died. The cutoff value based on the Youden index for the QIS discriminating those at high risk of mortality was 36.2% BM for overall, and we defined less than this cutoff point of QIS as low QIS. After adjustment for the HF risk score, the hazard ratio in low QIS was 1.55 for overall (95% confidence interval [CI], 1.17-2.06). The addition of low QIS to the HF risk score and gait speed was associated with significant increases in both net reclassification improvement (NRI, 0.239 for overall; 95% CI, 0.096-0.381) and integrated discrimination improvement (IDI, 0.004 for overall; 95% CI, 0.001-0.009) for all-cause mortality., Conclusion: Low QIS was strongly associated with poor prognosis and showed complementary prognostic predictive capability to the HF risk score and gait speed in older patients with HF., (Copyright © 2020 Canadian Cardiovascular Society.

Although heart failure (HF) and liver dysfunction often coexist because of complex cardiohepatic interactions, the association between liver dysfunction and physical dysfunction, and between coexistence of both and prognosis in HF patients remains unclear. We reviewed 895 patients with HF (mean age, 69.4 ± 14.2 years) who underwent liver function test using model for end-stage liver disease excluding international normalized ratio (MELD-XI) score and physical function test (grip strength, leg strength, gait speed, and 6-min walking distance [6MWD]). In the multiple regression analysis, MELD-XI score was independently associated with lower grip strength, leg strength, gait speed, and 6MWD (all P < 0.001). One hundred thirty deaths occurred over a median follow-up period of 1.67 years (interquartile range: 0.62-3.04). For all-cause mortality, patients with high MELD-XI scores and reduced physical functions were found to have a significantly higher mortality risk even after adjusting for several covariates (grip strength, hazard ratio [HR]: 3.80, P < 0.001; leg strength, HR: 4.65, P < 0.001; gait speed, HR: 2.49, P = 0.001, and 6MWD, HR: 5.48, P < 0.001). Liver dysfunction was correlated with reduced physical function. Moreover, the coexistence of lower physical function and liver dysfunction considerably affected prognosis in patients with HF.

Aims: There have been no investigations of the prevalence and clinical implications of coexistence of anaemia and frailty in older patients hospitalized with heart failure (HF) despite their association with adverse health outcomes. The present study was performed to determine the prevalence and prognostic value of the coexistence of anaemia and frailty in hospitalized older patients with HF., Methods and Results: We performed post hoc analysis of consecutive hospitalized HF patients ≥65 years old enrolled in the FRAGILE-HF, which was the prospective, multicentre, observational study. Anaemia was defined as haemoglobin < 13 g/dL in men and <12 g/dL in women, and frailty was evaluated according to the Fried phenotype model. The study endpoint was all-cause mortality. Of the total of 1332 patients, 1217 (median age, 81 years; 57.4% male) were included in the present study. The rates of anaemia and frailty in the study population were 65.7% and 57.0%, respectively. The patients were classified into the non-anaemia/non-frail group (16.6%), anaemia/non-frail group (26.4%), non-anaemia/frail group (17.7%), and anaemia/frail group (39.3%). A total of 144 patients died during 1 year of follow-up. In multivariate analyses, only the anaemia/frail group showed a significant association with elevated mortality rate (adjusted hazard ratio, 1.94; 95% confidence interval, 1.02-3.70; P = 0.043), compared with the non-anaemia/non-frail group after adjusting for other covariates., Conclusions: Coexistence of anaemia and frailty are prevalent in hospitalized older patients with HF, and it has a negative impact on mortality., (© 2020 The Authors.

Background & Aims: The Global Leadership Initiative on Malnutrition (GLIM) published a new international standard for defining malnutrition in 2018. The GLIM criteria were compared with the European Society for Clinical Nutrition and Metabolism (ESPEN) criteria in relation to physical function and mortality risk in patients with cardiovascular disease (CVD)., Methods: A total of 921 CVD patients ≥ 20 years old (67.8 ± 13.4 years, 631 men) hospitalised for heart failure, acute coronary syndrome and other conditions were stratified according to the presence or absence of malnutrition according to the GLIM and ESPEN criteria. Physical function was assessed by measuring grip strength, 6-minute walking distance and quadriceps isometric strength before hospital discharge, and the endpoint was all-cause mortality., Results: During the median follow-up period of 2.3 years (interquartile range, 0.9-3.5 years), 194 deaths occurred in the study population. Malnutrition defined by the GLIM criteria was significantly associated with low physical function. Malnutrition defined by both the GLIM and ESPEN criteria was significantly related to all-cause mortality (P < 0.05)., Conclusions: Malnutrition defined according to the GLIM criteria was a predictor of both low physical function and mortality in patients with CVD., Competing Interests: Conflicts of interest The authors declare there are no potential conflicts of interest with respect to the research, authorship and/or publication of this article., (Copyright © 2020 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Objective: In patients with kidney transplant (KT), frailty is a predictor of adverse outcomes. Outcomes of exercise therapy in patients with KT, particularly the efficacy of early exercise after KT, have not been evaluated. We investigated the effect of exercise intervention beginning early after KT on physical performance, physical activity, quality of life, and kidney function in patients with KT., Methods: KT recipients who underwent surgery with usual care plus exercise training from a prospective cohort (exercise group; n = 10) and those with usual care alone from a historical cohort (control group; n = 14) were included in this study. Early exercise comprised supervised aerobic training and physical activity instruction from day 6 to 2 months after KT. The following outcomes were measured: 6-minute walking distance, isometric knee extensor strength, gait speed, physical activity, quality of life, and estimated glomerular filtration rate., Results: Analyses of covariance, adjusted for baseline values, revealed significant mean differences between exercise and control groups at 2 months after KT in 6-minute walking distance (+44.4 m, P = .03) and isometric knee extensor strength (+8.1%body weight, P = .03). No significant between-group differences were found in gait speed, physical activity, and quality of life. The analysis of variance for comparison of the area under the recovery curves of estimated glomerular filtration rate after KT revealed no significant difference between groups., Conclusion: Supervised aerobic training and physical activity instruction initiated in the early phase after KT can improve physical performance without adversely affecting kidney function., (Copyright © 2020 National Kidney Foundation, Inc.

Aims: To describe the prevalence, overlap, and prognostic implications of physical and social frailties and cognitive dysfunction in hospitalized elderly patients with heart failure., Methods and Results: The FRAGILE-HF study was a prospective multicentre cohort study enrolling consecutive hospitalized patients with heart failure aged ≥65 years. The study objectives were to examine the prevalence, overlap, and prognostic implications of the coexistence of multiple frailty domains. Physical frailty, social frailty, and cognitive dysfunction were evaluated by the Fried phenotype model, Makizako's 5 items, and Mini-Cog, respectively. The primary study outcome was the combined endpoint of heart failure rehospitalization and all-cause death within 1 year. Among 1180 enrolled hospitalized patients (median age, 81 years; 57.4% male), physical frailty, social frailty, and cognitive dysfunction were identified in 56.1%, 66.4%, and 37.1% of the patients, respectively. The number of identified frailty domains was 0, 1, 2, and 3 in 13.5%, 31.4%, 36.9%, and 18.2% of the patients, respectively. During follow-up, the combined endpoint occurred in 383 patients. Adjusted hazard ratios for 1, 2, and 3 domains, with 0 domains as the reference, were 1.38 [95% confidence interval (CI) 0.89-2.13; P = 0.15], 1.60 (95% CI 1.04-2.46; P = 0.034), and 2.04 (95% CI 1.28-3.24; P = 0.003), respectively. Incorporating the number of frailty domains into the pre-existing risk model yielded a 22.0% (95% CI 0.087-0.352; P = 0.001) net reclassification improvement for the primary outcome., Conclusions: The coexistence of multiple frailty domains is prevalent in hospitalized elderly patients with heart failure. Holistic assessment of multi-domain frailty provides additive value to known prognostic factors., (© 2020 European Society of Cardiology.)

Aims: The area of the pupil can be used as an indicator of autonomic function. However, the relation between pupil area and prognosis in heart failure (HF) patients remains unclear. This study was performed to examine whether pupil area can be used as a prognostic indicator in patients with HF., Methods and Results: This retrospective review was performed in 870 consecutive patients (mean age: 67.0 ± 14.1 years, 37.0% women) hospitalized for acute HF. Pupil area was measured with a pupilometer at least 7 days after hospitalization for HF. The primary endpoint was all-cause mortality, and the secondary endpoint was readmission due to HF. A total of 131 patients died, and 328 patients were readmitted because of HF over a median follow-up of 1.9 (interquartile range: 1.0-3.7 years) years. After adjustment for several pre-existing prognostic factors, including Seattle Heart Failure Score (SHFS), pupil area was shown to be independently associated with all-cause mortality (hazard ratio: 0.72; 95% confidence interval: 0.59-0.88; P = 0.001) and readmission due to HF (hazard ratio: 0.82; 95% confidence interval: 0.73-0.93; P = 0.003). Addition of pupil area to SHFS significantly increased the area under the receiver-operating characteristic curve for all-cause mortality (0.69 vs. 0.72, respectively; P = 0.034)., Conclusions: Pupil area is an independent predictor of all-cause mortality and readmission due to HF and adds prognostic information to SHFS in patients with HF. The results presented here suggest that pupil area may be useful as a prognostic marker in patients with HF., (© 2020 The Authors.

Background: There has been no study elucidating whether cognitive impairment (CI) can provide additive prognostic information besides that provided by preexisting prognostic factors in elderly patients with heart failure. This study examined whether CI can provide additive prognostic information in elderly patients with heart failure., Methods: This multicenter retrospective study included 352 patients with heart failure aged ≥75 years. We administered the Mini-Mental State Examination (MMSE) and Mini-Cog test to assess CI. The Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) risk score was used as a model to incorporate the preexisting prognostic factors. All-cause mortality was considered the prognostic outcome., Results: The median age was 85 years old, 47.7% were male. According to MMSE and Mini-Cog, 167 (47.4%) and 159 (45.2%) patients had CI, respectively. The agreement between MMSE and Mini-Cog was fairly low (Cohen's kappa coefficient 0.37). During the follow-up period of median 346 days, 53 patients (15.1%) died. In multivariate Cox regression analysis, CI defined by MMSE and Mini-cog were individually associated with worse prognosis in older heart failure patients even after adjustment for MAGGIC risk model and log B-type natriuretic peptide levels [CI defined by MMSE, HR: 2.05 (95%CI: 1.16-3.61); and CI defined by Mini-Cog, HR:2.57 (95%CI: 1.46-4.53)]. The area under the curve of receiver operator characteristics curve was numerically greater for Mini-Cog than for MMSE (0.59 vs. 0.52, p = 0.109). Moreover, significant net reclassification improvement was observed when CI defined by Mini-Cog, but not on CI defined by MMSE, was added to the MAGGIC score, and when Mini-Cog, instead of MMSE, was used as a CI assessment tool (0.41, p = 0.004)., Conclusions: Among elderly hospitalized patients with heart failure, CI should be considered as a critical factor for prognosis prediction. Mini-Cog is a potentially preferable tool to assess CI in terms of providing prognostically relevant information compared to MMSE., (Copyright © 2020 Japanese College of Cardiology.

Background: The early prediction of frailty at discharge in elderly patients hospitalized with heart failure (HF) is essential for clinical management and therapeutic decision-making. This study was performed to examine whether the rising time from bed measured immediately after admission can be used as a predictor of frailty in these patients., Methods: A retrospective cohort study was performed in a population of 387 consecutive elderly patients with HF. Rising time from bed was measured within 2 days after admission when cardiac rehabilitation was started. Frailty was assessed at hospital discharge using a composite of four markers as a frailty score (range, 0-12): gait speed, handgrip strength, serum albumin, and activities of daily living status. The patients were divided into two groups based on frailty score <5 (non-frail) or ≥5 (frail)., Results: The study population had a mean age of 75 years and 63.6 % were men. The median rising time was 6.8s, and 53.5 % were classified as frail. After adjustment for various factors, rising time was independently associated with frailty (odds ratio=1.10; 95 % confidence index=1.04-1.18). The area under the receiver operating characteristics curve of rising time for frailty was 0.71, and the cut-off value for rising time to identify those at high risk of frailty was 7.1s., Conclusions: Rising time from bed measured within 2 days after admission was shown to be an independent predictor of frailty at hospital discharge in elderly patients hospitalized for HF., (Copyright © 2019 Japanese College of Cardiology.
