Psychosocial interventions effective for smoking cessation in patients with coronary heart disease
How effective are psychosocial interventions for smoking cessation in patients with coronary heart disease (CHD)?
After a cardiac event about 30% to 50% of smokers with CHD quit without professional help. Additional psychosocial interventions showed a superior quitting rate (NNT* 14.9) compared to usual care in the short-term (six to 12 months). Long-term (>12 months) follow-up showed an attenuation in the benefit of psychosocial interventions for smoking cessation. Interventions consisted of behavioural therapeutic approaches, telephone support and self-help material. Brief interventions were not effective. Adverse effects were not reported in any trial.
*NNT = number needed to treat to benefit one individual.
The trials mostly included older male patients with CHD, predominantly myocardial infarction. Heterogeneity between trials was substantial.
Smoking increases the risk of developing atherosclerosis but also acute thrombotic events. Quitting smoking is potentially the most effective secondary prevention measure and improves prognosis after a cardiac event, but more than half of these patients continue to smoke, and improved cessation aids are urgently required.
