OBJECTIVETo investigate the status quo of smoking cessation and analyze factors influencing smoking cessation in cigarette smoking patients with coronary artery disease (CAD).

METHODA total of 350 smoking patients with CAD was surveyed by questionnaire, logistic regression analysis was performed to analyze factors influencing smoking cessation.

RESULTSIncidence of smoking cessation was 57.1% (200/350) in this cohort. Patients were divided into two groups, the elderly (> 65 years old, n = 111) and the young group (≤ 65 years old, n = 239). The smoking cessation rate in the elderly group is significantly higher than in the young group (71.2% vs. 50.6%, P < 0.001). Aged patients and patients with high cultural level are easier to give up smoking. Logistic analysis showed that age ≤ 65 years old (OR = 2.336, P = 0.004), low cultural level (OR = 1.310, P = 0.028), PCI (OR = 0.261, P < 0.001), coronary artery bypass graft (OR = 0.107, P = 0.004), total family income > 4000 RMB/month (OR = 1.828, P = 0.003) are risk factors for failed smoking cessation. There are 76 patients smoking again in current smokers, most due to lack of self-control (76.3%). Compared to the elderly group, there is a higher proportion of smoking again due to the need of daily communication and work in the young group.

CONCLUSIONSWe still need to raise the awareness of smoking cessation for smoking patients with CAD. Following factors should be focused for tobacco control in CAD patients: younger age, lower cultural level, not treated with PCI or CABG, patients with smoking family members, higher body mass index and higher total family income.
