predictors of smoking resumption after acute coronary syndrome: a prospective study inwestern iran

Background: despite the health benefits of smoking cessationonpatients with cardiovascular diseases (cvds), someresume smoking even after their discharge from hospital with acute coronary syndrome (acs). objectives: this study aimed to determine the predictors of smoking resumption after acs in western iran. patients and methods: this prospective cohort study was performed on 175 patients admitted to the imam ali cardiovascular center, kermanshah, iran, with a diagnosis of acs from january 2018 to december 2018. data were collected by a trained interviewer using a checklist developed based on the study objectives. differences between groups were evaluated by independent t-test, chisquare, and fisher’s exact tests. the relationship between smoking resumption and predicting variables was assessed using univariate and multivariate logistic regression models (forward lr). results: all participants were male with a mean age of 56.30 ± 8.91 (mean ± sd) years. three months post-discharge, 137 (78.3%) patients quit smoking, and 38 (21.7%) patients resumed it. the patientswhoresumed smoking were more likely to be divorced (20.6% vs. 0.7%), unemployed or retired (73.7% vs. 63.5%), have smokers in household (86.8% vs. 50.4%), and have history of depression (52.7% vs. 20.4%) (p-values < 0.05). the independent predictors of smoking resumption were divorce (or 4.2, 95% ci: 1.31 - 19.01), having smokers in household (or 12.08, 95% ci: 3.45 - 40.81), and history of depression (or 12.16, 95% ci: 3.68 - 39.04). conclusions: divorce, having smokers in household, and history of depression were identified as the independent predictors of smokingresumption inacspatients. thosewhohave these characteristics shouldbe viewed ashaving a high risk of smokingrelapse and be provided with more support to quit smoking.
