Key result
Secondhand smoke exposure linked to ~127% greater risk of persistent smoking after CAD hospitalization.
Why the study?
Smoking cessation in patients with CAD reduces cardiovascular events, but factors related to persistent smoking needed evaluation.
What factors are associated with persistent smoking in patients with established coronary artery disease?
Population
1034 patients aged 80 years or younger hospitalized for ACS or myocardial revascularization
Comparison
Persistent smokers vs patients who quit smoking
Design
Survey
Follow-up
6 to 18 months

Persistent smoking after CAD hospitalization supports enhanced cessation efforts; hypothesis-generating for secondhand smoke exposure as a modifiable factor.
Cross-Sectional (n=1,034)

What factors are associated with persistent smoking in patients with established coronary artery disease?
Odds Ratio: 2.27 (95% CI 1.35–3.84)
p-value: p=0.002
More than half of patients who smoke prior to hospitalization for CAD continue to smoke 6 to 18 months later, highlighting a need for targeted cessation strategies.
Kozieł et al. (2021) conducted a cross-sectional in Coronary artery disease (n=1,034). Secondhand smoke exposure vs. No secondhand smoke exposure was evaluated on Persistent smoking at 6 to 18 months follow-up (OR 2.27, 95% CI 1.35-3.84, p=0.002). Over half (54.7%) of smokers hospitalized for coronary artery disease remained persistent smokers 6 to 18 months after discharge, with secondhand smoke exposure significantly increasing this risk (OR 2.27).
