Smoking cessation after discharge among Japanese patients with established ischemic heart disease: a prospective cohort study.
In this prospective cohort study for Japanese patients with established ischemic heart disease (IHD), the authors investigated the rate of success of smoking cessation 3 months after hospital discharge and its related factors. The subjects included 90 current smokers admitted for IHD. A total of 58 subjects (64%) had quit smoking for 3 months after being discharged. In comparison with subjects with acute myocardial infarction, those with stable angina (SA) showed a significantly lower frequency of smoking cessation (relative risk of resuming smoking (95% confidence interval):2.06 (1.09, 3.92), p=0.036). This relationship remained significant even after controlling for sex, age, and scores of the Fagerstrom Test for Nicotine Dependence (adjusted odds ratio:3.39 (1.01, 11.37), p=0.048). However, it became insignificant when hospital admission followed by emergency medical service (EMS) care was additionally adjusted (adjusted odds ratio:2.48 (0.36, 16.97), p=0.356). The smoking cessation rate in this study was identical to that observed in studies conducted in Japan prior to the recent social changes with regard to tobacco use. SA still appears to be a risk factor for smoking resumption after discharge. Experiencing EMS care would be an intermediate variable in this relationship.
