Changes in walking speed 6 months after discharge may be more sensitive to subsequent prognosis than handgrip strength in patients hospitalized for heart failure.

Background: Despite the prognostic importance of walking speed (WS) and handgrip strength (HGS) in patients with heart failure (HF), no study has reported the prognostic impact of changes in these parameters. This study aimed to examine the association between changes after discharge and the subsequent prognosis.

Methods: This study included 881 elderly patients hospitalized for HF.

Association Between Liver Function and Peak Oxygen Uptake in Heart Failure Patients: A Retrospective Observational Study.

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).

Effectiveness of interval training compared with endurance training in cardiac rehabilitation.

Anaerobic endurance training (AET) can improve sympathomimetic hyperactivity, and anaerobic interval training (AIT) is recommended for patients who cannot exercise due to exertional breathlessness and leg fatigue. However, the difference in sympathetic nerve activation (SNA) and parasympathetic nerve activation (PNA) during AIT and AET is unclear. The aim of this study is to investigate the differences between endurance and interval trainings.
