RESUMEN
BACKGROUND: This study determined the incidence of hospitalization-associated disability (HAD) and its characteristics in older patients with heart failure in Japan. METHODSâANDâRESULTS: Ninety-six institutions participated in this nationwide multicenter registry study (J-Proof HF). From December 2020 to March 2022, consecutive heart failure patients aged ≥65 years who were prescribed physical rehabilitation during hospitalization were enrolled. Of the 9,403 patients enrolled (median age 83.0 years, 50.9% male), 3,488 (37.1%) had HAD. Compared with the non-HAD group, the HAD group was older and had higher rates of hypertension, chronic kidney disease, and cerebrovascular disease comorbidity. The HAD group also had a significantly lower Barthel Index score and a significantly higher Kihon checklist score before admission. Of the 9,403 patients, 2,158 (23.0%) had a preadmission Barthel Index score of <85 points. Binomial logistic analysis revealed that age and preadmission Kihon checklist score were associated with HAD in patients with a preadmission Barthel Index score of ≥85, compared with New York Heart Association functional classification and preadmission cognitive decline in those with a Barthel Index score <85. CONCLUSIONS: This nationwide registry survey found that 37.1% of older patients with HF had HAD and that these patients are indicated for convalescent rehabilitation. Further widespread implementation of rehabilitation for older patients with heart failure is expected in Japan.

The effectiveness of cardiac rehabilitation (CR) in patients with cardiovascular disease requiring continuous CR from an acute care hospital to a convalescent rehabilitation hospital is unknown. Therefore, we compared the effect of CR in a rehabilitation hospital for patients with cardiovascular disease with that of those who underwent cardiovascular surgery. Sixty-nine consecutive patients were admitted to two rehabilitation hospitals for CR. Patients were classified by primary disease into two groups: patients with cardiovascular disease (cardiology group, 26 patients) and patients who underwent cardiovascular surgery (surgery group, 43 patients). Clinical information, physical function, cognitive function, activities of daily living (ADL), quality of life (QOL), amount of CR, and length of hospital stay were compared between the two groups. Compared with clinical features, age was significantly higher in the cardiology group (P < 0.001), and the preadmission Barthel index was significantly lower in the cardiology group (P = 0.025). Physical function at the time of transfer was significantly lower in the cardiology group than in the surgery group for the short physical performance battery (P < 0.001), gait speed (P = 0.005), and 6-min walking distance (P = 0.042). No significant difference was found in the amount of CR performed or the length of hospital stay, and no interaction effects were observed in improvements in physical function, exercise tolerance, or QOL. In conclusion, in rehabilitation hospitals, patients with cardiovascular disease were older, had lower preadmission ADL, and had lower a physical function at transfer than those who underwent cardiovascular surgery, but CR improved physical function and QOL to the same extent. The results suggest that the recovery of patients with cardiovascular disease may be similar to those who undergo cardiovascular surgery.

AIM: Circulating blood volume (BV) during exercise changes depending on the intensity and duration, and post-exercise hypotension is observed after continuous exercise. We investigated the safety and efficacy of both interval and continuous IDE at anaerobic threshold (AT) levels with respect to hemodynamic stability and dialysis efficiency. METHODS: In this crossover randomized controlled trial, 16 patients on haemodialysis were subjected to three trial arms, including non-IDE, interval-IDE, and continuous-IDE arms. Systolic blood pressure (SBP), BV, and ultraviolet absorbance - an indicator of dialysis efficiency - were continuously measured, and each change was compared between the three arms by two-way analysis of variance. RESULTS: Continuous IDE decreased SBP from post-exercise to the end of dialysis compared with baseline (pre 142.8 ± 19.0 vs. post 127.5 ± 24.5 mmHg, p = .02), whereas interval IDE maintained better SBP levels post-exercise (pre 139.9 ± 17.1 vs. post 140.1 ± 15.8 mmHg, p = 1.0) than continuous IDE (non-IDE 133.2 ± 19.9 vs. interval 140.1 ± 15.8 vs. continuous 127.5 ± 24.5 mmHg, p = .04). Moreover, interval IDE caused less tiredness and few symptoms (p < .05), despite reaching higher intensity than continuous IDE (p = .001). The BV of each IDE arm decreased during exercise and recovered post-exercise to the same level as non-IDE. Ultraviolet absorbance was not different between each arm (p = .16). CONCLUSION: AT-level interval IDE maintains better hemodynamic stability from post-exercise to the end of dialysis and may represent a novel approach that can be effectively performed with fewer symptoms.

BACKGROUND: Hospital-acquired functional decline (HAFD) is a new predictor of poor prognosis in hospitalized older patients. AIMS: We aimed to assess the impact of HAFD on the prognosis of older cardiac surgical patients 2 years after discharge. METHODS: This multicenter prospective cohort study assessed 293 patients with cardiac disease aged ≥ 65 years who underwent cardiac surgery at 7 Japanese hospitals between June 2017 and June 2018. The primary endpoint was the composite outcome of cardiovascular-related readmission and all-cause mortality 2 years after discharge. HAFD was assessed using the total Short Physical Performance Battery at hospital discharge. RESULTS: The primary outcome was observed in 17.3% of the 254 included patients, and HAFD was significantly associated with the primary outcome. Female sex (hazard ratio [HR], 2.451; 95% confidence interval [CI] 1.232-4.878; P = 0.011), hemoglobin level (HR, 0.839; 95% CI 0.705-0.997; P = 0.046), preoperative frailty (HR, 2.391; 95% CI 1.029-5.556; P = 0.043), and HAFD (HR, 2.589; 95% CI 1.122-5.976; P = 0.026) were independently associated with the primary outcome. The incidence rate of HAFD was 22%, with female sex (odds ratio [OR], 1.912; 95% CI 1.049-3.485; P = 0.034), chronic obstructive pulmonary disease (OR, 3.958; 95% CI 1.413-11.086; P = 0.009), and the time interval (days) between surgery and the start of ambulation (OR, 1.260, 95% CI 1.057-1.502; P = 0.010) identified as significant factors. DISCUSSION: HAFD was found to be an independent prognostic determinant of the primary outcome 2 years after discharge. CONCLUSION: HAFD prevention should be prioritized in the hospital care of older cardiac surgery patients.

OBJECTIVE: Postexercise vagal dysfunction is linked to noncardiovascular mortality in hemodialysis patients, but the mechanism is unknown. This study aimed to determine the association of cardiovagal neuropathy with systemic inflammation, protein-energy wasting, and noncardiovascular hospitalization. METHODS: This 2-center retrospective cohort study analyzed data from 280 hemodialysis patients who underwent exercise test. Patients were assessed for heart rate (HR) recovery (bpm) for 1 minute after exercise, a marker of vagal function, and were divided into 3 categories (Low: ≤ 6, Mid: 7-11, High: ≥ 12 bpm). We followed 1-year changes in the systemic inflammation-based prognostic score (Glasgow Prognostic Score [GPS]), body weight, and creatinine generation rate (CGR), an indicator of muscle mass, as well as 2-year hospitalization. RESULTS: The HR recovery category was associated with serum C-reactive protein and albumin levels and GPS. After 1 year, the low HR recovery category was associated with worsening in GPS (low, 0 [0-0.5]; mid, 0 [0-1]; high, 0 [0-0]), weight (low, 100.0 [96.1-102.5]; mid, 101.3 [98.9-105.0]; high, 100.5 [98.2-102.9]%), and CGR (low, 97.0 [88.5-111.4]; mid, 110.2 [90.9-124.8]; high, 106.2 [95.5-115.5]%), and the correlations with GPS and CGR remained consistent after adjusting for confounders such as exercise capacity and hospitalization during the follow-up period. There were 117 patients hospitalized. Compared to the high HR recovery category, the mid (hazard ratio: 1.8, 95% confidence interval [CI]: 1.1-3.1, P = .02) and low (hazard ratio: 2.4, 95% CI: 1.5-4.0, P = .001) categories were independently associated with an increased risk of all-cause hospitalization. For noncardiovascular disease hospitalization, the low HR recovery category was independently associated with increased risk of hospitalization (hazard ratio: 2.1, 95% CI: 1.2-3.7, P = .007). CONCLUSIONS: Vagal neuropathy in this population can contribute to adverse outcomes associated with systemic inflammation and protein-energy wasting.
RESUMEN
The heart rate (HR) reflects the dynamic behavior of the autonomic nervous system, and HR profiles during the exercise test provide prognostic information. However, there are no reports of these factors in hemodialysis patients. Data from 256 patients (mean 68.8 years old) who underwent an exercise test were statistically analyzed. Patients were evaluated for the percent HR reserve from HR at peak exercise, HR recovery for one minute after peak exercise, and exercise capacity, as well as intradialytic hypotension (IDH). The prevalence of chronotropic incompetence (96.1%), defined as under 80% HR reserve, and abnormal HR recovery (60.5%), defined as under 12 beats, were very common. Eighty-four deaths occurred during the follow-up period (median, 3.8 years). A slow HR recovery under 7 beats was associated with IDH after adjustment (odds ratio 2.7, 95% confidence interval 1.1-6.4). HR recovery under 12 beats (hazard ratio over study period 5.1, 95% confidence interval 2.5-10.5), HR reserve under 26.2% (3.4, 1.7-6.8), and IDH (1.7, 1.1-2.8) were associated with all-cause mortality after adjustment. Considering the confounding of all three variables, only HR recovery under 12 beats remained associated with the all-cause and cause-specific mortality ("cardiovascular" and "non-cardiovascular"). This association was consistent even in subgroup analyses based on the presence of diabetes and cardiovascular disease. Thus, HR profiles during the exercise can reflect potential health conditions related to cardiac autonomic neuropathy in hemodialysis patients that affect IDH and their survival.

BACKGROUND: Following cardiovascular surgery, patients are at high risk of requiring systemic management in the intensive care unit (ICU), resulting in hospitalization-associated disability (HAD). Predicting the risk of HAD during the postoperative course is important to prevent susceptibility to cardiovascular events. Assessment of physical function during the ICU stay may be useful as a prediction index but has not been established. METHODS: This prospective observational study conducted at a high-volume cardiovascular center included 236 patients (34% female; median age, 73 years) who required an ICU stay of at least 72 hours after surgery and underwent postoperative rehabilitation. HAD was defined as a decrease in the discharge Barthel index (BI) score of at least 5 points relative to the preadmission BI score. Physical Function ICU Test-scored (PFIT-s), Functional Status Score for the ICU (FSS-ICU), and Medical Research Council (MRC)-sumscore were used to assess physical function at ICU discharge. RESULTS: HAD occurred in 58 (24.6%) of the 236 patients following cardiovascular surgery. The cut-off points for HAD were 7.5 points for the PFIT-s (sensitivity 0.80, specificity 0.59), 24.5 points for the FSS-ICU (sensitivity 0.57, specificity 0.66), and 59.5 points for the MRC-sumscore (sensitivity 0.93, specificity 0.66). Multivariate logistic regression analysis revealed a PFIT-s of >7.5 points (odds ratio [OR], 4.84; 95% CI, 2.39-9.80; p < 0.001) and an MRC-sumscore of >59.5 points (OR, 2.43; 95% CI, 1.22-4.87; p = 0.012) as independent associated factors. CONCLUSIONS: We demonstrate that the PFIT-s and MRC-sumscore at ICU discharge may be helpful as a predictive indicator for HAD in patients having undergone major cardiovascular surgery.

BACKGROUND: The COVID-19 pandemic has required an increased need for rehabilitation activities applicable to patients with chronic diseases. Telerehabilitation has several advantages, including reducing clinic visits by patients vulnerable to infectious diseases. Digital platforms are often used to assist rehabilitation services for patients in remote settings. Although web portals for medical use have existed for years, the technology in telerehabilitation remains a novel method. OBJECTIVE: This scoping review investigated the functional features and theoretical approaches of web portals developed for telerehabilitation in patients with chronic diseases. METHODS: PubMed and Web of Science were reviewed to identify articles associated with telerehabilitation. Of the 477 nonduplicate articles reviewed, 35 involving 14 portals were retrieved for the scoping review. The functional features, targeted diseases, and theoretical approaches of these portals were studied. RESULTS: The 14 portals targeted patients with chronic obstructive pulmonary disease, cardiovascular, osteoarthritis, multiple sclerosis, cystic fibrosis diseases, and stroke and breast cancer survivors. Monitoring/data tracking and communication functions were the most common, followed by exercise instructions and diary/self-report features. Several theoretical approaches, behavior change techniques, and motivational techniques were found to be utilized. CONCLUSIONS: The web portals could unify and display multiple types of data and effectively provide various types of information. Asynchronous correspondence was more favorable than synchronous, real-time interactions. Data acquisition often required assistance from other digital tools. Various functions with patient-centered principles, behavior change strategies, and motivational techniques were observed for better support shifting to a healthier lifestyle. These findings suggested that web portals for telerehabilitation not only provided entrance into rehabilitation programs but also reinforced participant-centered treatment, adherence to rehabilitation, and lifestyle changes over time.

Heart failure and frailty share aging as a strong risk factor. The prevalence of frailty has been shown to be particularly high in elderly patients with heart failure. Moreover, it is important not to confine frailty to physical aspects. Rather, it should be considered to consist of multiple domains, including physical disability, psychiatric disorders, cognitive impairment, depression, and social disconnection. Development of interventions that can improve frailty domains are not well established, although observational studies have evaluated the association of various frailty domains and their prognostic impact. Some interventions, including resistance exercise, functional exercise, and respiratory muscle training have been demonstrated to hold potential for improving physical frailty. In terms of cognitive dysfunction, previous studies have demonstrated that exercise therapy is also effective for cognitive dysfunction. The social domain of frailty is one of the least investigated domains, particularly in patients with heart failure. However, heart failure is also strongly associated with physical frailty and cognitive impairment and has a poor prognosis in old patients. The prevalence of social frailty in elderly patients who need hospitalization due to heart failure is higher than previously thought. Very few studies have tested interventions targeting social frailty. Frailty and heart failure affect each other, and both are becoming increasingly important in society. In this article, we review the physical, cognitive, and social domains of frailty and the possible interventions to improve them in patients with heart failure.

This study examined quality indicators (QIs) for heart failure (HF) in patients' referral documents (PRDs).We conducted a nationwide questionnaire survey to identify information that general practitioners (GPs) would like hospital cardiologists (HCs) to include in PRDs and that HCs actually include in PRDs. The percentage of GPs that desired each item included in PRDs was converted into a deviation score, and items with a deviation score of ≥ 50 were defined as QIs. We rated the quality of PRDs provided by HCs based on QI assessment.We received 281 responses from HCs and 145 responses from GPs. The following were identified as QIs: 1) HF cause; 2) B-type natriuretic peptide (BNP) or N-terminal pro-BNP concentration; 3) left ventricular ejection fraction or echocardiography; 4) body weight; 5) education of patients and their families on HF; 6) physical function, and 7) functions of daily living. Based on QI assessment, only 21.7% of HCs included all seven items in their PRDs. HCs specializing in HF and institutions with many full-time HCs were independently associated with including the seven items in PRDs.The quality of PRDs for HF varies among physicians and hospitals, and standardization is needed based on QI assessment.

BACKGROUND: Advanced glycation end-products, indicated by skin autofluorescence (SAF) levels, could be prognostic predictors of all-cause and cardiovascular mortality in patients with diabetes mellitus (DM) and renal disease. However, the clinical usefulness of SAF levels in patients with heart failure (HF) who underwent cardiac rehabilitation (CR) remains unclear. This study aimed to investigate the associations between SAF and MACE risk in patients with HF who underwent CR. METHODS: This study enrolled 204 consecutive patients with HF who had undergone CR at our university hospital between November 2015 and October 2017. Clinical characteristics and anthropometric data were collected at the beginning of CR. SAF levels were noninvasively measured with an autofluorescence reader. Major adverse cardiovascular event (MACE) was a composite of all-cause mortality and unplanned hospitalization for HF. Follow-up data concerning primary endpoints were collected until November 2017. RESULTS: Patients' mean age was 68.1 years, and 61% were male. Patients were divided into two groups according to the median SAF levels (High and Low SAF groups). Patients in the High SAF group were significantly older, had a higher prevalence of chronic kidney disease, and more frequently had history of coronary artery bypass surgery; however, there were no significant between-group differences in sex, prevalence of DM, left ventricular ejection fraction, and physical function. During a mean follow-up period of 590 days, 18 patients had all-cause mortality and 36 were hospitalized for HF. Kaplan-Meier analysis showed that patients in the high SAF group had a higher incidence of MACE (log-rank P < 0.05). After adjusting for confounding factors, Cox regression multivariate analysis revealed that SAF levels were independently associated with the incidence of MACE (odds ratio, 1.86; 95% confidence interval, 1.08-3.12; P = 0.03). CONCLUSION: SAF levels were significantly associated with the incidence of MACE in patients with HF and may be useful for risk stratification in patients with HF who underwent CR.

BACKGROUND: The purpose of this study was to clarify the current status and issues of community collaboration in heart failure (HF) using a nationwide questionnaire survey.MethodsâandâResults:We conducted a survey among hospital cardiologists and general practitioners (GPs) using a web-based questionnaire developed with the Delphi method, to assess the quality of community collaboration in HF. We received responses from 46 of the 47 prefectures in Japan, including from 281 hospital cardiologists and 145 GPs. The survey included the following characteristics and issues regarding community collaboration. (1) Hospital cardiologists prioritized medical intervention for preventing HF hospitalization and death whereas GPs prioritized supporting the daily living of patients and their families. (2) Hospital cardiologists have not provided information that meets the needs of GPs, and few regions have a community-based system that allows for the sharing of information about patients with HF. (3) In the transition to home care, there are few opportunities for direct communication between hospitals and community staff, and consultation systems are not well developed. CONCLUSIONS: The current study clarified the real-world status and issues of community collaboration for HF in Japan, especially the differences in priorities for HF management between hospital cardiologists and GPs. Our data will contribute to the future direction and promotion of community collaboration in HF management.

Arterial stiffness contributes to the development of cardiovascular disease (CVD). However, the relationship between the arterial stiffness and exercise tolerance in CVD patients with preserved ejection fraction (pEF) and those with reduced EF (rEF) is unclear. We enrolled 358 patients who participated in cardiac rehabilitation and underwent cardiopulmonary exercise testing at Juntendo University Hospital. After excluding 195 patients who had undergone open heart surgery and 20 patients with mid-range EF, the patients were divided into pEF (n = 99) and rEF (n = 44) groups. Arterial stiffness was assessed using arterial velocity pulse index (AVI) and arterial pressure volume index (API) at rest. The patients in the pEF group were significantly older and had a higher prevalence of coronary artery disease than the rEF group. The pEF group had significantly lower AVI levels and higher API levels than the rEF group. In the pEF group, the peak oxygen uptake (peak VO2) and the anaerobic threshold was significantly higher than those in the rEF group. The peak VO2 was significantly and negatively correlated with AVI and API in the pEF group (All, P < 0.05), but not in the rEF group. Multivariate linear regression analyses demonstrated that AVI was independently associated with peak VO2 (ß = -0.34, P < 0.05) in the pEF group. In conclusion, AVI may be a useful factor for assessing exercise tolerance, particularly in CVD patients with pEF.

BACKGROUND: This study aimed to assess the relationship between hospital-acquired functional decline and the risk of mid-term all-cause death in older patients undergoing transcatheter aortic valve implantation (TAVI).MethodsâandâResults:In total, 463 patients (mean age 85 years, interquartile range [IQR]: 82, 88) undergoing elective TAVI at Sakakibara Heart Institute between 2010 and 2018, who were followed up for 3 years, were enrolled in the study. Hospital-acquired functional decline after TAVI, which was defined by at least a 1-point decrease on the Short Physical Performance Battery before discharge compared to the preoperative score, was assessed. A total of 113 patients (24.4%) showed hospital-acquired functional decline after TAVI, and 50 (11.3%) patients died over a mean follow-up period of 1.9±0.8 years. Kaplan-Meier survival curves indicated that hospital-acquired functional decline was significantly associated with all-cause mortality (log-rank test, P=0.001). On multivariate Cox regression analysis, hospital-acquired functional decline was associated with a higher risk of all-cause mortality (OR 2.108, 95% CI 1.119-3.968, P=0.021) independent of sex, body mass index, advanced chronic kidney disease, and preoperative frailty, as assessed by the modified essential frail toolkit. CONCLUSIONS: Hospital-acquired functional decline is associated with mid-term all-cause mortality in older patients following TAVI. Trajectory of functional status is a vital sign, and it is useful for risk stratification in older patients following TAVI.

BACKGROUND: Phase angle (PA), measured by bioelectrical impedance analysis (BIA) has been studied as indicator of nutritional status or muscle function in hemodialysis (HD) patients. It remains unclear if the phase angle is associated protein-energy wasting (PEW) or frailty, which are common complication in hemodialysis patients. The aim of this study is to determine whether BIA-derived PA is a marker of PEW or frailty in HD patients. METHODS: This retrospective observational study included 116 adult HD patients (35% female, 64 ± 12 years of age) in a single dialysis center. Patients were classified according to the PA quartiles into four groups; 1) first quartile: PA < 3.7°, 2) second quartile: PA 3.7-4.1°, 3) third quartile: PA 4.2-4.9°and 4) forth quartile: PA ≥ 5.0°. International Society of Renal Nutrition and Metabolism (ISRNM) criteria and Japanese version of Cardiovascular Health Study (J-CHS) criteria were used to identify PEW and frailty. RESULTS: The lower PA group was associated with a greater risk of PEW (35% vs. 24% vs. 21% vs. 3%; p = 0.032), frailty (59% vs. 40% vs. 21% vs. 3%; p < 0.001). In multivariate logistic regression analysis, the first quartile group was at a significantly greater risk of both PEW and frailty compared with the fourth quartile group after adjusting for other confounding factors. CONCLUSIONS: Lower PA was associated with a greater risk of PEW and frailty in HD patients.

[Purpose] Although cardiac rehabilitation (CR) is recommended for patients with chronic heart failure (CHF), adequate exercise effect cannot be obtained in elderly patients. Administration of amino acids (AA) to CHF patients has been reported to improve exercise capacity, but the changes in AA composition in plasma before and after CR had not been reported. This study aimed to measure plasma levels of AA in CHF patients and compare with values of normal range. In addition the relationship between the change of exercise capacity and AA were examined. [Subjects and Methods] Twelve CHF patients (60% males, aged 68 ± 12â years) were studied. The correction between the rates of changes in exercise capacity parameters and in plasma AA levels was investigated. [Results] Anaerobic threshold (AT) and peak oxygen uptake (VO2) improved significantly after CR. The AA profile showed no specific pattern, and citrulline (Cit) was the amino acid showing a significant positive correlation with exercise capacity (∆Cit vs. ∆AT: r=0.602, ∆Cit vs. ∆AT-work rate (WR): r=0.681, ∆Cit vs. ∆VO2/WR: r=0.635). A tendency of positive correlation was observed between ∆Cit and ∆peak VO2 (r=0.456). [Conclusion] The AA profile showed no specific pattern, but a relationship between change in exercise capacity and Cit were found.
RESUMEN
[Purpose] This study aimed to elucidate characteristics of postoperative physical functional recovery in octogenarians undergoing coronary artery bypass graft surgery. [Subjects and Methods] This was a multi-center, retrospective study. Nine hundred and twenty-seven elective isolated coronary artery bypass graft surgeries were evaluated (746 males and 181 females, mean age: 68.6â years, range: 31-86 years). Participants were stratified according to age < 80â years (n = 840; mean age, 67.1; range, 31-79) or > 80â years (n = 87; mean age, 82.2; range, 80-86). Patient characteristics and postoperative physical functional recovery outcomes were compared between groups. [Results] There was no significant difference between groups when considering the postoperative day at which patients could sit on the edge of the bed, stand at bedside, or walk around the bed. The postoperative day at which patients could walk 100â m independently was later in octogenarians, when compared with non-octogenarians (6.1 ± 3.2 days vs. 4.9 ± 3.9 days). In octogenarians, the percentage of patients who could walk 100â m independently within 8 days after surgery was 79.5%. [Conclusion] A postoperative target time in octogenarians for independent walking, following coronary artery bypass grafting, can be set at approximately 6 days.
RESUMEN
PURPOSE: This study aimed to examine factors that delay weaning from ventilation after cardiac surgery. METHODS: A retrospective examination was made on 1,033 patients who had undergone cardiac surgery through a midsternal incision between January 2009 and July 2011. The items examined were duration of postoperative ventilation, patient's background, and other surgical information. If patients were weaned within 24 hours from intensive care unit (ICU) admission, they were included in the timely weaning group. If patients required 24 hours or more to be weaned, they were included in the delayed weaning group. RESULTS: There was a relationship between prolonged ventilation and the following factors: emergency surgery, history of arrhythmia, history of motor system disorder, preoperative estimated glomerular filtration rate (eGFR), preoperative New York Heart Association (NYHA) classification, preoperative left ventricular ejection fraction (LVEF), operative method, operative time, blood loss, intraoperative fluid management, and number of days from surgery until achievement of independent gait. The independent factors delaying extubation were emergency surgery, preoperative NYHA classification, preoperative LVEF, operative method, operative time, blood loss, and intraoperative fluid management(p<0.05). CONCLUSION: Surgical invasiveness and preoperative heart failure were involved in the prolonged ventilation after cardiac surgery.

Daily health management and exercise are important for staying healthy and avoiding the need for long-term care. However, it is not easy to maintain regular exercise. Therefore, exercise needs to be done efficiently. In recent years, due to the aging population and increasing severity of illness, older patients often experience a significant decline in physical function, even with minimal rest, which often interferes with their daily life after discharge from the hospital. Frailty not only affects ADLs, but also strongly influences prognosis, including the development of atherosclerotic disease and rehospitalization. This perspective is a summary of the 51st Metropolitan Public Lecture held on June 17, 2023, and discusses exercise-based rehabilitation programs that can be delivered at home to prevent physical frailty and avoid hospitalization-related disability.
RESUMEN
OBJECTIVE: Patients on hemodialysis are highly susceptible to falls and fractures. Amplified apprehension regarding the fear of falling (FOF) constitutes a risk factor that restricts physical activity and escalates the probability of falls among the elderly population. This study aimed to elucidate the association between falls and FOF and physical activity in patients on hemodialysis. METHODS: A prospective cohort study was conducted across 9 centers. FOF was assessed using the Falls Efficacy Scale-International (FES-I). Physical activity was assessed using the Japanese version of the International Physical Activity Questionnaire short form. Subsequently, falls were monitored over a duration of 1 year. Logistic regression analysis was performed to evaluate the relationship between falls and FOF and physical activity. In addition, in the receiver operating characteristic analysis, the cutoff value of FES-I that predicts falls was determined using the Youden Index. A restricted cubic spline curve was utilized to analyze the nonlinear association between falls and the FES-I. RESULTS: A total of 253 patients on hemodialysis (70.0 [59.0-77.0] years old; 105 female [41.5%]) were included in the analysis. During the 1-year observation period, 90 (35.6%) patients experienced accidental falls. The median FES-I score was 36.0 (24.0-47.0) points, and patients with higher FES-I scores had more falls. Following adjusted logistic regression analysis, FES-I exhibited an independent association with falls (OR = 1.04; 95% CI = 1.01-1.06), but physical activity was not. The area under the receiver operating characteristic curve was 0.70 (95% CI = 0.64-0.77), and the FES-I threshold value for distinguishing fallers from non-fallers was determined as 37.5 points (sensitivity 65.6%, specificity 35.0%). A nonlinear relationship between falls and FES-I was observed. CONCLUSION: FOF was associated with the incidence of falls in patients on hemodialysis. IMPACT: The evaluation and implementation of interventions targeting the FOF may mitigate the risk of falls.
