Early rehabilitation improves walking capacity after acute heart failure
Hospital patients whose acute heart failure had stabilized walked farther after early exercise-based rehabilitation than comparison groups in a pooled analysis of randomized trials. Programmes began during admission and sometimes continued after discharge. The clearest benefit concerned walking capacity; sparse clinical-event data left effects on death and readmission uncertain, and overall evidence certainty for the walking result was low.

Walking improves after clinical stabilization
Patients beginning structured exercise rehabilitation during hospital care for acute heart failure gained walking capacity compared with control groups. A single peer-reviewed systematic review brought together 12 randomized trials with 1,317 participants. Rehabilitation began after clinical stabilization, and the pooled difference in the six-minute walking test was 54.44 m. The result concerns supervised programmes in the studied patients, rather than an exercise instruction for people in the unstable acute phase.[1]
Programmes continued along different paths
Eight trials delivered rehabilitation during admission alone; four also continued it after discharge. Researchers searched five databases through May 2026, covering studies published from 2011 to 2025. Differences in programme content and outcome timing complicated comparisons. Seven trials carried high risk of bias, and certainty in the walking result was rated low. Excluding those trials still left an estimated gain of about 48 metres.[1]
Clinical-event evidence stays uncertain
Some disease-specific quality-of-life measures improved, although different scales were evaluated separately. Data on death and readmission came from relatively few trials. The examined outcomes showed no statistically significant difference, leaving considerable uncertainty about those clinical effects. Walking gains therefore remain separate from an established survival benefit.[1]
