Smoking control after percutaneous coronary intervention in coronary heart disease patients

Objective To elucidate the situation of giving up smoking after percutaneous coronary intervention(PCI)in patients with coronary artery disease in order to analyze the gap between the real situation and evidence-based medicine.Methods 299 patients with coronary artery disease who had undergone PCI and followed up for 6 months were studied.Results The rates of smoking on admission and follow-up period were 47.5%(142/299)and 23.1%(69/299),respectively.During follow-up,35.9%(51/142)of the in-hospital smokers continued smoking,whereas 11.5%(18/157)of the non-smokers during hospitalization became cigarette addict despite a marked reduction in the general rate of smoking(P=0.003).All the patients were divided into elderly group(65years)and non-elderly group(≤65years).Compared with the elderly group,the non-elderly group had a higher rate of recurrent smoking(52.8% vs 41.5%,P=0.023),a lower rate of giving up smoking(32.6% vs 49.1%,P=0.012)and a higher rate of new smokers(20.3% vs 5.4%,P=0.001)during follow-up period.Conclusion The situation of giving up smoking after PCI is far beyond optimal,with a high rate of continued smoking and poor control of smoking.Prompt and effective measures should be taken to enhance the education to the people,especially young patients to minimize the gap between clinical practice and evidence-based guidelines.
