To study the effect of invasive coronary angiography (ICA) as opposed to non-invasive investigations (NII) for coronary artery disease (CAD) on smoking cessation.
Methods:
All smokers who underwent ICA and NII by exercise stress test or methoxyisobutylisonitrile scan between November 2010 and February 2011 were recruited. Subjects were called by telephone 1-4 months following the investigation and asked regarding tobacco use. Success was verified by carbon monoxide monitoring in 60% of quitters. Results were analysed using statistical package for social sciences v.17.0.
Results:
46.5% who underwent NII (no=111) and 34% who underwent ICA (no=64) were contacted (NII mean age 53.5 years, 62% male; ICA mean age 55.9 years, 75% male). More ICA patients recall being told to stop smoking 98.4% vs. 84% (p=0.001), more received written advice 37.5% vs. 15.9 % (p=0.001), and more were advised to attend smoking cessation classes 34.4% vs. 20.6% (p=0.046). There was no difference in prescription of pharmacotherapy 29.7% vs. 24.3% (p=0.436). More ICA patients tried to quit 82.8% vs. 60.7% (p=0.03) with 41% vs. 8% succeeding respectively (p<0.05).
Conclusion
ICA patients are more likely to quit smoking than NII patients. This could be partially explained by more aggressive attempts at smoking cessation counselling.
