“…Consequently, the average step count (6,752±2,659 steps/day) in this investigation was slightly higher than that reported from earlier evaluations of a chronic disease population. [12][13][14]23 These findings are not surprising given that our participants regularly attended the CRP and they were also likely to have a greater functional capacity than the subjects observed in the aforementioned studies. Although the average step count for the subjects in the presents study corresponded to the minimal goal for PAEE in secondary prevention (1,500 kcal/week) ( Table 2), 48% of patients failed achieve this minimal goal.…”

“…10 The reported average daily step count for a group of peripheral arterial disease patients was nearly 4,500 steps/day 12 and it ranged from 3,500-4,300 steps/day in heart disease patients. 13,14,23 Hoodless et al demonstrated that chronic heart failure patients had a 60% reduction in step count compared with age-matched healthy controls. 23 In the present investigation, the mean observed step count was 5,491±2,805 steps/day for non-CRP days, and 8,499±3,173 steps/day on CRP days.…”

“…10,11 Pedometers simply measure step counts, but this basic information is highly correlated with other physical activity parameters (caloric expenditure, time spent distribution) as well as quality of life and overall prognosis. [10][11][12][13][14][15] Numerous researchers have recommended that individuals should accumulate 10,000 steps per day to prevent cardiovascular disease, as well as diabetes, obesity, and certain cancers. 10,11 Although this is a very practical and reasonable goal for most, 10,000 steps per day may be inappropriate for sedentary individuals, older individuals, and/or those with chronic health conditions such as cardiac disease.…”

“…23 Therefore, this type of less artificial means of continuous daily assessment is valuable in identifying patients at high risk and provides an objective measure of incapacity over a longer time period within the normal everyday environment. The ALI value, a novel monitoring feature that is an objective measurement of functional capacity, has potential for wide clinical use, and the impact of this on HF management should be further evaluated in larger controlled studies.…”

xercise intolerance is a hallmark of heart failure (HF) and is predictive of all-cause mortality and hospitalizations. 1,2 Discouraging a sedentary lifestyle and promoting physical activity have both been shown to improve functional capacity, quality of life, and clinical outcome. 3,4 Cardiac resynchronization therapy (CRT) restores the cardiac electro-mechanical synchrony, leading to improved pumping function in HF patients with ventricular conduction disturbances. Consequently, CRT is able to increase functional capacity, exercise tolerance, 5,6 and aerobic capacity, 7 to delay the onset of anaerobic metabolism, 5 and to decrease the sympathetic drive of the heart. 8 All these effects have been reported mainly in CRT patients with sinus rhythm (SR) within a few months after device implantation. 5,6 Long-term exercise data in HF patients treated with CRT are limited. Furthermore, etiology-, rhythm-, diabetes-, and age-related differences in the improvement in functionCirculation Journal Vol.71, December 2007 al capacity after CRT have not yet been fully evaluated.The 6-min walking test is frequently used to assess submaximal exercise capacity in HF patients treated with CRT. 5,9 However, the distance walked is influenced by several factors, including patient motivation, coaching, anatomical limitations, and physical training. Furthermore, in HF patients variability in the distance walked between 2 subsequent tests is frequently observed. 10 In contrast, symptom-limited exercise testing, eventually combined with an assessment of oxygen consumption, is influenced by familiarity with the test and may not reflect the patient's spontaneous daily physical activity, plus its routine determination is costly and time-consuming.Recent technological advances have made device-based monitoring of physical activity possible using data collected through the device's sensors. 11 Short-term, continuous, device-based monitoring of physical activity has proven to be feasible, although in a limited number of patients to date. 12 Because each device uses proprietary technology and analysis algorithms, the results obtained with 1 device may not be entirely applicable to other devices. Finally, whether this monitoring remains of value over the long term and in different subgroups of HF patients is unknown. It has been shown that the Activity Log Index (ALI), which quantifies body movement based on data derived from accelerometers built into the device, reliably tracks changes in the daily, spontaneous physical activity of patients with advanced HF. In addition, the ALI is well correlated with the distance walked within 6 min. 11 The aim of this study was to prospectively investigate the validity of long-term device-based monitoring of physical activity in advanced HF patients treated with CRT.

“…It has been shown that bilirubin is independently associated with morbidity and mortality. [4][5][6][7][8] Changes in total bilirubin levels may offer insight into the underlying pathophysiology of chronic HF. 4) Furthermore, looking at the relationship between liver dysfunction and exercise capacity, the 6-minute walking distance (6MD) increased significantly after liver transplantation, compared with the pre-transplantation value.…”

Objective: With respect to liver function and heart failure, 46% of acute decompensated heart failure patients exhibit abnormal liver function. However, there have been no reports of the association between liver function and functional capacity in these patients. Our aim was to clarify the relationship between liver function and functional capacity using the peak oxygen uptake (VO 2 ). Methods: We retrospectively identified 36 heart failure patients who were referred to our rehabilitation laboratory. These patients underwent cardiopulmonary exercise testing (CPX). Furthermore, we investigated the correlations between peak VO 2 , blood measurements [e.g., total bilirubin (T-bil) and brain natriuretic peptide], and echocardiographic parameters. Finally, multivariate regression analysis was performed to investigate the independent variables related to peak VO 2 . Results: The mean peak VO 2 was 10.7±2.9 ml/kg/min. Peak VO 2 during CPX correlated inversely with T-bil [r=-0.379, 95% confidence intervals (CI): −0.654 to −0.014, P=0.043], aspartate transaminase (r=-0.426, 95% CI: −0.685 to −0.07, P=0.021), and peak heart rate (r=0.391, 95% CI: 0.029 to 0.663, P=0.036). The significant independent factors associated with peak VO 2 were treatment with statin (β=-3.19, P=0.015) and T-bil levels (β=-4.27, P=0.002). Conclusion: Our findings demonstrated that liver function may contribute to the functional capacity in heart failure patients.
