PURPOSE: The aim of this study was to examine the relationship between exercise tolerance, functional status, exercise behavior, and enrollment in cardiac rehabilitation (CR), preoperatively in individuals undergoing coronary artery bypass graft (CABG) surgery.


METHODS: Seventy-eight individuals undergoing CABG were evaluated 1 to 7 days preoperatively using the following measures: 2-minute walk test (2MWT), Duke Activity Status Index (DASI), Cardiac Exercise Self-Efficacy Instrument (CESEI), Stages of Change Questionnaire (SCQ), Short-Form 12 (SF-12), Hospital Anxiety Depression scale, location of residence, and education level. Participants were contacted via telephone 10 to 12 weeks postoperatively to determine if they were referred and enrolled in CR. Participants completed mailed questionnaires for follow-up. In subsequent telephone interviews, individuals who were not enrolled in CR were asked to provide reasons for nonenrollment.


RESULTS: Overall enrollment in CR was 46%. No significant differences were found in 2MWT, CESEI, and DASI scores between enrolled and nonenrolled participants. Fifty-seven percent of urban-dwelling participants enrolled in CR compared to 29% of rural-dwelling participants (P < .01). Similarly, 65% of individuals with post-secondary education enrolled in CR compared to 38% of individuals without a post-secondary education (P = .05). The primary reasons for nonenrollment were behavioral intentions toward exercise and CR, accessibility, and healthcare team recommendation. Individuals who enrolled in CR demonstrated a larger postoperative improvement in CESEI score.


CONCLUSIONS: Location of residence and education level predicted CR enrollment, whereas preoperative exercise tolerance, functional status, and exercise attitudes did not predict enrollment.
