Is participation in cardiac rehabilitation programs associated with better quality of life and return to work after coronary artery bypass operations? The Israeli CABG Study.
OBJECTIVE
To explore the putative effect of cardiac rehabilitation programs on the 'health-related quality of life' and 'return to work' in pre-retirement patients one year after coronary artery bypass grafting.


METHODS
Of the 2,085 patients aged 45-64 who survived one year after CABG and were Israeli residents, 145 (6.9%) had participated in rehabilitation programs. Of these, 124 (83%) who answered QOL questionnaires were individually matched with 248 controls by gender, age within 5 years, and the time the questionnaire was answered. All patients had full clinical follow-up including a pre-operative interview. The Short Form-36 QOL questionnaire as well as a specific questionnaire were mailed to surviving patients one year after surgery. Study outcomes included the scores on eight scales and two summary components of the SF-36, as well as 'return to work' and 'satisfaction with medical services' from the specific questionnaire. Analysis was done for matched samples.


RESULTS
Cardiac rehabilitation participants had significantly higher SF-36 scores in general health, physical functioning, and social functioning. They had borderline significant higher scores in the physical summary component of the SF-36. The specific questionnaire revealed significantly better overall functioning, higher satisfaction with medical care, and higher rate of return to work. While participants in cardiac rehabilitation and their controls were similar in their socio-demographic and clinical profiles, participating patients tended to be more physically active and more fully employed than their controls.


CONCLUSIONS
Rehabilitation participants had a self-perception of better HRQOL, most significantly in social functioning. Our findings of more frequent return to work and higher satisfaction with medical care should induce a policy to encourage participation in cardiac rehabilitation programs after CABG.
