  • Recent study strengthens the case for smoking cessation interventions in ACS patients

  • The prevalence of smoking among patients with acute coronary syndrome (ACS) is high in China. However, there remains a lack of clinical interventions for smoking cessation as part of formal ACS treatment strategies, hence indicating an important target for care improvement initiatives.

    This is according to a registry study derived from the Improving Care for Cardiovascular Disease in China project, a collaborative nationwide registry of the American Heart Association and the Chinese Society of Cardiology. The study sample comprised 92,509 ACS inpatients admitted between November 2014 and December 2018. 

    Data showed that smoking prevalence among male and female ACS patients was 52.4% and 8.0%, respectively. Patients younger than 45 years had the highest smoking rate (men, 68.0%; women, 14.9%). Smokers had an earlier onset age of ACS and a greater proportion of severe clinical manifestations at admission, including ST-elevation myocardial infarction, compared with non-smokers (67.8% vs 54.8%; p<0.001), and substantially elevated myocardial injury markers (86.1% vs 83.0%; p<0.001). After multivariable adjustment, smoking was associated with higher risk of critical cardiac symptoms at admission (odds ratio, 1.14; 95% confidence interval, 1.08–1.20; p<0.001), but not significantly associated with in-hospital outcomes of ACS patients. 

    Lastly, only 35.3% of the 37,336 smokers with ACS received smoking cessation interventions before discharge, and the provision of smoking cessation interventions varied widely across hospitals (0–100%).
