Objectives: Rehabilitation of patients following coronary artery bypass grafting (CABG) has been widely studied; however, research into early rehabilitation after CABG is sparse. The aim of this trial was to assess the impact of early rehabilitation, compared with usual care in patients following CABG. Design: Randomized controlled trial. Patients: A total of 326 patients treated with CABG. Methods: Patients treated with CABG were randomized 1:1 to 4 weeks of comprehensive early rehabilitation or usual care. The primary outcome was the Six Minute Walk Test (6MWT). Secondary outcomes were mental health and physical activity (Medical Outcome Study Short Form; SF-12); anxiety and depression (Hospital Anxiety and Depression Scale; HADS); physical and emotional scores; sleep (Pittsburgh Sleep Quality Index; PSQI); pain (Örebro Musculoskeletal Screening Questionnaire; ÖMSQ) and muscle endurance (Sit-To-Stand test). Results: Sixteen patients dropped out. No significant differences between groups in the primary outcome (6MWT) were found after 4 weeks (p = 0.27). For secondary outcomes the odds ratio of HADS-D ≥ 8 decreased in favour of the experimental intervention (p = 0.04). There was non-adherence to parts of the intervention. Per-protocol analysis showed differences between groups for the 6MWT (p = 0.02) and the Sit-To-Stand test (p = 0.046). Conclusion: In general, the intervention had no effect on the 6MWT, or secondary outcomes, except for depressive symptoms. However, in adherent participants, the intervention had a positive effect for the primary and several secondary outcomes.
