Background: Prior studies suggest that cardiac rehabilitation (CR) attendance improves smoking cessation rates, but it is unclear if CR services can be credited for this beneficial impact, or, rather, if CR attendance is predicted by a successful smoking cessation attempt. Which comes first?
Methods: Between October 2015 and May 2016, we administered two sequential surveys to hospitalized smokers who were eligible for CR. At baseline we asked smokers about their intentions to enroll in CR and quit smoking; 4 to 8 weeks later, we determined whether patients quit smoking and whether they attended CR. We also asked patients how they felt their smoking status influenced their decision to attend/not attend CR.
Results: Of the 105 patients approached, 81 (77%) patients completed the baseline survey (68% male, 57 ± 10 years, 78% with MI and/or PCI) and 62 (77%) completed the follow-up survey. Overall, 36 (44%) of patients attended CR and 38 (47%) abstained from smoking. There was a strong correlation between smoking cessation at the time of follow-up and CR attendance (OR 16.0, p < 0.001). Most patients (n=39, 63%) felt their smoking behavior had no impact on their decision to attend CR. However, 5 patents (8%) attended CR because they quit smoking, 5 (8%) felt CR would help them to quit smoking long-term, and 13 (21%) did not provide a clear or complete response. Among 15 baseline factors, it was notable that 3 of the 5 multivariate factors predictive of CR attendance suggested an intertwined role of smoking cessation and exercise intentions: abstinence from smoking at follow-up, intention to use exercise as a smoking cessation strategy, and prior participation in regular exercise.
Conclusions: A strong relationship exists between smoking cessation, exercise, and CR attendance, but this relationship is more likely associative rather than causative, although a few patients report intending to use CR to help them stay quit. However, regardless of reason, the low success rates with smoking cessation and CR attendance in this study suggest that improved efforts to support smoking cessation and CR attendance are urgently needed.
