Factors Influencing Successful Smoking Cessation after Acute Coronary Syndrome

Takeaway

• 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.

Study design

• UK researchers conducted a meta-analysis of 39 studies (n=11,228), identified through a literature search across electronic databases.

• Funding: None.

Key results

• 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):

  • depression (0.57; 0.43-0.75);

  • COPD/lung disease (0.73; 0.57-0.93);

  • previous admission with acute myocardial infarction/cardiac admission (0.61; 0.47-0.80);

  • cerebrovascular disease/TIA (0.42; 0.30-0.58); and

  • unemployment (0.37; 0.17-0.80).

Limitations

• Many studies were prospective in nature.
