Abstract

Objectives This study sought to assess a novel physical rehabilitation intervention in older patients hospitalized for acute decompensated heart failure (ADHF). Background After ADHF, older patients, who are frequently frail with multiple comorbidities, have prolonged and incomplete recovery of physical function and remain at high risk for poor outcomes. Methods The REHAB-HF (Rehabilitation Therapy in Older Acute Heart Failure Patients) pilot study was a 3-site, randomized, attention-controlled pilot study of a tailored, progressive, multidomain physical rehabilitation intervention beginning in the hospital and continuing for 12 weeks post-discharge in patients ≥60 years hospitalized with ADHF. The primary purpose was to assess the feasibility and reasonableness of the hypothesis that the novel rehabilitation intervention would improve physical function (Short Physical Performance Battery [SPPB]) over 3 months and reduce all-cause rehospitalizations over 6 months. Results The study enrolled 27 patients with ADHF (ages 60 to 98 years; 59% women; 56% African American; 41% with preserved ejection fraction [≥45%]). At baseline, participants had marked impairments in physical function, multiple comorbidities, and frailty. Study retention (89%) and intervention adherence (93%) were excellent. At 3 months, an intervention effect size was measured for the SPPB score of +1.1 U (7.4 ± 0.5 U vs. 6.3 ± 0.5 U), and at 6 months an effect size was observed for an all-cause rehospitalization rate of −0.48 (1.16 ± 0.35 vs. 1.64 ± 0.39). The change in SPPB score was strongly related to all-cause rehospitalizations, explaining 91% of change. Conclusions These findings support the feasibility and rationale for a recently launched, National Institutes of Health–funded trial to test the safety and efficacy of this novel multidomain physical rehabilitation intervention to improve physical function and reduce rehospitalizations in older, frail patients with ADHF with multiple comorbidities.
