OBJECTIVE: To estimate fatigue during and after a multidisciplinary cardiac
rehabilitation programme and its association with aerobic capacity. DESIGN:
Longitudinal cohort study. PATIENTS: A total of 121 patients with coronary artery
disease (79% men), mean age 57 years. METHODS: Fatigue was measured with the
Fatigue Severity Scale (FSS) and aerobic capacity with the 6-min walk test
(6MWT). FSS scores >/= 4 were defined as fatigue and > 5.1 as severe fatigue.
Measurements were taken before (T0) and after rehabilitation (T1) and at 1-year
follow-up (T2). RESULTS: Fatigue decreased from 3.49 at baseline to 3.03
post-rehabilitation (p = 0.002) and decreased further to 2.75 at follow-up (p <
0.001 vs T0). At baseline, 17.7% of patients were classified as severely
fatigued. After cardiac rehabilitation, the prevalence decreased to 10.6% (p <
0.001) and to 8.1% at follow-up (p = 0.011 vs T0). Although the prevalence of
severely fatigued patients decreased, it was still high compared with healthy
individuals (3.5%). Aerobic capacity was weakly associated with a reduction in
fatigue (p = 0.030). CONCLUSION: Fatigue decreased during and after cardiac
rehabilitation. However, the prevalence of severely fatigued patients remained
high after cardiac rehabilitation. Fatigue should be identified at an early stage
in order to provide additional programmes aiming to reduce severe fatigue.
