Objectives: Rehabilitation of patients following coro-
nary artery bypass grafting (CABG) has been widely
studied; however, research into early rehabilitation
after CABG is sparse. The aim of this trial was to as-
sess 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 randomi-
zed 1:1 to 4 weeks of comprehensive early rehabili-
tation 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 de-
pression (Hospital Anxiety and Depression Scale;
HADS); physical and emotional scores; sleep (Pitts-
burgh Sleep Quality Index; PSQI); pain (Örebro Mus-
culoskeletal 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 se-
condary outcomes the odds ratio of HADS-D ≥ 8 de-
creased in favour of the experimental intervention
(p = 0.04). There was non-adherence to parts of the
intervention. Per-protocol analysis showed differen-
ces between groups for the 6MWT (p = 0.02) and the
Sit-To-Stand test (p = 0.046).
Conclusion: In general, the intervention had no ef-
fect on the 6MWT, or secondary outcomes, except
for depressive symptoms. However, in adherent par-
ticipants, the intervention had a positive effect for
the primary and several secondary outcomes.
Key words: rehabilitation post-CABG; phase 1 rehabilitation;
early rehabilitation; coronary artery bypass grafting; physical
exercise; psycho-education.

LAY ABSTRACT
This trial investigated the effects of an early rehabilita-
tion programme in addition to usual care for patients
undergoing heart bypass surgery. The programme con-
sisted of exercise training and 4 planned nurse consul-
tations in the period from admission to 4 weeks after
surgery. The programme was tested by 163 patients
undergoing heart bypass surgery, compared with a si-
milar number of patients who followed usual care alone.
The trial did not show any effect of the programme on
physical function, but there was a positive effect in re-
ducing depressive symptoms in the rehabilitation group.
Although the rehabilitation programme was scheduled,
adherence was low. The reason for lack of efficacy could
be poor adherence to the programme, as patients who
followed the programme significantly improved in terms
of physical functioning 4 weeks after surgery. The re-
sults provide important information for health professio-
nals for refining early rehabilitation programmes after
heart bypass surgery.
C
ardiac rehabilitation is differentiated into 3 main
phases: in-hospital (phase 1); early outpatient
(phase 2), and long-term outpatient (phase 3) cardiac
rehabilitation (1). Clinical recommendations for phase
1 rehabilitation for patients undergoing coronary artery
bypass graft (CABG) surgery are few, and are based
on sparse evidence from trials with small sample sizes
and non-representative trial populations (2, 3). Patients
with chronic conditions can receive surgical treatment
(3); however, the postoperative period can be challen-
ging, with physical and psychological problems and
symptoms such as anxiety and depression, immobility
issues, respiratory complications, insufficient sleep,
and fatigue (4–6).
Exercise training after hospital discharge has demon-
strated positive benefits (7), and it seems reasonable
to start exercise training immediately after CABG
surgery (8). Trials have demonstrated improvements
in outcomes, measured by pulmonary complications
