Factors affecting smoking cessation in patients with cardiovascular disease

  AIM  To evaluate the impact of related factors on smoking cessation in patients with cardiovascular disease.

  METHODS  Patients receiving health education for smoking cessation were followed up for 12 months and divided into an effective group (n = 156) and an ineffective group (n = 188) according to smoking cessation results. Each group was assessed on the effects of related factors on smoking cessation.

  RESULTS  The rate of successful smoking cessation was higher in older patients (e.g., older than 70 years) patients with coronary artery disease, hypertension, heart failure, or less smoking (≤10 cigarettes/day)(all P < 0.01) and was lower in patients living in solitude or in close contact with smokers (both P < 0.01) during the follow-up period. Logistic multi-factor regression analysis showed that coronary artery disease, heart failure, less smoking, smoking exposure and living state were independent factors influencing rate of successful smoking cessation. Coronary heart disease, heart failure, and less smoking improved and living alone and smoking exposure reduced efficiency of smoking cessation.

  CONCLUSION  Severe illness can improve the efficiency of smoking cessation; however, living alone and contacting smokers did not improve efficiency of smoking cessation.
