Worsening Physical Function during Hospitalization is Associated with Poor Outcome in Patients with Acute Decompensated Heart Failure

Abstract

Recent reports have indicated a marked impairment of physical function in patients with acute cardiac disease. In addition, further deterioration in physical activity has been found during hospitalization especially in elderly patients, which may be associated with poor outcome after discharge. In this study, we repeatedly measured gait speed (GS) during hospitalization and evaluated the association of change in GS with mortality after discharge.
