| Popis: | Previous studies have shown that smoking cessation after a cardiac event reduces the risk of subsequent mortality in patients. The aim of this study was to describe the effect of smoking cessation in terms of prolonged life-years gained. The study sample comprised 856 patients who underwent percutaneous coronary intervention (PCI; balloon angioplasty) during 1980 to 1985. Patients were followed up for 30 years and smoking status at 1 year could be retrieved in 806 patients. The 27 patients who died within 1 year were excluded from the analysis. The median follow-up was 19.5 years (interquartile range 6.0 to 23.0). Cumulative 30-year survival rate was 29% in the group of patients who quit smoking and 14% in persistent smokers (p = 0.005). After adjustment for baseline characteristics at the time of PCI, smoking cessation remained an independent predictor of lesser mortality (adjusted hazard ratio 0.57, 95% confidence interval 0.46 to 0.71). The estimated life expectancy was 18.5 years in those who quit smoking and 16.4 years in the persistent smokers (p < .0001). In conclusion, in patients with coronary heart disease who underwent PCI in the late 1980s, smoking cessation resulted in at least 2.1 life-years gained. (C) 2013 Elsevier Inc. All rights reserved. |
