Smoking Cessation Strategies After Acute Coronary Syndrome

Smoking is one of the strongest modifiable risk factors for coronary artery disease. It is the cause of approximately 10-30% of deaths due to cardiovascular disease around the world. There is a 50% reduction in the risk of myocardial infarction by one year for people who successfully quit smoking. Considering the risk associated with smoking and the benefits of smoking cessation, it is important to identify and implement effective smoking cessation strategies. There are pharmacological as well as non-pharmacological interventions to assist in smoking cessation. Pharmacological therapies including nicotine replacement therapy; bupropion and varenicline have generally been studied more in patients with cardiovascular disease than the non-pharmacological interventions. Non-pharmacological strategies for smoking cessation include behavioural interventions such as counselling sessions and cognitive behavioural therapy. Studies and randomised controlled trials have demonstrated the safety of most of the pharmacological interventions. Nonetheless, the success rates are variable for the different pharmacological options. Data suggest that greater success can be achieved in smoking cessation with a combination of pharmacological and non-pharmacological treatment. However, more studies are needed to explore the best therapeutic options to improve the success of smoking cessation.
