RESUMEN
OBJECTIVE: To evaluate the abstinence rate and relapse rate of smoker with ACS after discharged from hospital, to evaluate the effect of simple smoking cessation interventions. METHODS: 150 smokers with ACS were collected and was divided into simple intervention group (n = 87) and control group (n = 63), respectively, followed up for 6 months. 2 months, 6 months abstinence rate, relapse rate were compared between two groups, logistic regression model was used to analyzed the relevant factors for relapse. RESULTS: The smoking rate in patients with ACS was 31.14%, 6-month continuous abstinence rate and 6-month relapse rate was 64.6%, 36.4%, respectively. 6-month continuous abstinence rate and relapse rate between simple quit-smoking intervention group and control group showed no difference. Nicotine dependence score more than 4 points can be used as predictor of relapse. CONCLUSIONS: The smoking rate and the abstinence rate of smoker with ACS is higher than the general population, simple quit-smoking intervention do not increase the success rate of quit-smoking, indicated the need to strengthen the intervention in patients with ACS and smoking.
