Passive smoking and smoking cessation among patients with coronary heart disease across Europe: results from the EUROASPIRE III survey.

Passive smoking is the inhalation of environmental tobacco smoke (ETS) and is a risk factor for coronary heart disease (CHD). We aimed to describe the frequency of passive smoking among patients with CHD and to investigate the association between ETS exposure and smoking cessation. METHODS AND RESULTS: The EUROASPIRE III survey was conducted in 2006-07 among CHD patients up to 80 years of age from 22 European regions. Patients were interviewed and examined on average 15 months after hospital admission for CHD. Information was obtained on smoking prior to hospital admission, smoking at interview, and ETS exposure at home, at work, and at other locations. Breath carbon monoxide was measured to validate self-reported non-smoking. Among 8729 patients, 6060 (69.4%) were non-smokers prior to hospital admission, of whom 10.3% reported ETS exposure at home, 7.2% at work, and 13.8% at other locations. Overall, 24.2% of non- smokers were exposed to ETS at any place. Among the 2669 patients who were smoking prior to hospital admission, the likelihood of cessation at interview was lower in those with ETS exposure at home than in those without [25.3 vs. 58.1% ; adjusted odds ratio (OR) 0.26, 95% confidence interval (CI) 0.20-0.33]. This finding applied also to ETS exposure at work (32.2 vs. 52.7% ; adjusted OR 0.56, 95% CI 0.42-0.76) and at other locations (38.0 vs. 52.8% ; adjusted OR 0.63, 95% CI 0.48-0.84). CONCLUSION: A noteworthy proportion of non-smokers with CHD are exposed to ETS. Passive smoking may jeopardize smoking cessation among CHD patients.
