Most smokers with acute coronary syndrome (ACS) continue to smoke after hospital admission.
A meta-analysis identified factors influencing the likelihood of quitting smoking successfully and risk factors for smoking relapse.
Why this matters
Findings suggest that smoking cessation after ACS should be given the attention it deserves, in conjugation with other secondary prevention measures.
UK researchers conducted a meta-analysis of 39 studies (n=11,228), identified through a literature search across electronic databases.
The pooled rate of smoking cessation after ACS was 45.0% (4824/10,726) across 38 studies.
Factors associated with a greater likelihood of smoking cessation were (OR; 95% CI):
attending cardiac rehabilitation (1.90; 1.44-2.51);
married/not alone (1.68; 1.32-2.13);
intention/attempt to quit smoking (1.27; 1.11-1.46);
diabetes mellitus (1.24; 1.03-1.51); and
longer duration of hospitalisation (1.09; 1.02-1.15).
Factors associated with a lower likelihood of smoking cessation were (OR; 95% CI):
Many studies were prospective in nature.
