Objective: To investigate the smoking cessation rate and its related factors in cardiovascular patients after percutaneous coronary intervention.
Methods: A cross-sectional survey of 1241 outpatients or inpatients fulfilling the inclusion criteria was conducted at 14 hospitals across China.
Results: The survey population mainly consisted of middle-aged male patients with an average age of (59.9 ± 10.7) years old. Their median time after surgery was 1.5 years. Among them, 77.4% tried to quit smoking while 55.4% succeed. The elder men were more likely to try to quit smoking and succeed eventually (OR values: 1.02 vs 1.03). The higher number of cigarettes smoked daily, the greater possibility of trying to quit smoking (OR = 1.03), but less likely to quit smoking eventually (OR = 0.97). Furthermore the years of smoking and cessation motivation had impacts on the cessation behaviors as well.
Conclusion: Smoking cessation was achieved in more than half of the patients at one year after PCI. Age, years of smoking, daily number of cigarettes, concurrent diseases and physician recommendations are the influencing factors of smoking cessation.
