Background
Participation rates in cardiac rehabilitation following myocardial infarction (MI) remain low. Studies investigating the predictive value of psychosocial variables are sparse and often qualitative. We aimed to examine the demographic, clinical, and psychosocial predictors of participation in cardiac rehabilitation after MI in the community.
Methods
Olmsted County, Minnesota residents hospitalized with MI between June 2004 and May 2006 were prospectively recruited, and a 46-item questionnaire was administered prior to hospital dismissal. Associations between variables and cardiac rehabilitation participation were examined using logistic regression.
Results
Among 179 survey respondents (mean age 64.8 years, 65.9% male), 115 (64.2%) attended cardiac rehabilitation. The median (25th–75th percentile) number of sessions attended within 90 days of MI was 13 (5–20). Clinical characteristics associated with rehabilitation participation included younger age (odds ratio [OR] 0.95 per 1-year increase), male sex (OR 1.93), lack of diabetes (OR 2.50), ST elevation MI (OR 2.63), receipt of reperfusion therapy (OR 7.96), in-hospital cardiologist provider (OR 18.82), no prior MI (OR 4.17), no prior cardiac rehabilitation attendance (OR 3.85), and referral to rehabilitation in the hospital (OR 12.16). Psychosocial predictors of participation included placing a high importance on rehabilitation (OR 2.35), feeling that rehabilitation was necessary (OR 10.11), better perceived health prior to MI (excellent vs. poor OR 7.33), the ability to drive (OR 6.25), and post-secondary education (OR 3.32).
Conclusions
Several clinical and psychosocial factors are associated with decreased participation in cardiac rehabilitation programs after MI in the community. As many are modifiable, addressing them may improve participation and outcomes.
