Background Coronary artery bypass grafting surgery (CABG) is a common treatment for coronary artery disease. The patient’s commitment to modify risk factors is necessary to achieve the desired after surgery outcomes. The current study aimed at determining illness perception of patients after CABG, its relation to smoking cessation, and detecting other predictors of smoking cessation. Methods The samples of the current cross sectional study were selected from a greater study that was done on patients’ adherence determining for 6 months after CABG surgery. Data collection was performed using a telephone questionnaire with 3 sections: personal and social information, smoking cessation, and illness perception. Data analysis was performed via descriptive statistics, independent t test, and multiple logistic regression analysis through SPSS version 16. Results The findings showed that 26.6% of the patients had not stopped smoking for 6 months after CABG, and the mean score of illness perception was 83.28 ± 6.11. The relationship between adherence to smoking cessation and illness perception was not significant. Regression logistics via backward selection to detect factors related to smoking cessation adherence after CABG showed only a lack of hypertension history could predict adherence to smoking cessation (OR = 0.199, P = 0.03). Conclusions Based on the results, about one-third of the subjects smoked cigarettes after CABG; therefore, it is critical to plan rehabilitation programs regarding smoking cessation after this surgery.
