Abstract：Objective To analyze the epidemiological characteristics and tendency distribution of smoking in patients with acute coronary heart disease (ACHD) in Tianjin. Methods Utilizing the smoking information collected from the Incidence Surveillance System for Main Chronic Diseases in Tianjin, we investigated the prevalence of ACHD in Tianjin during 2010-2014, and then analyzed the epidemiological characteristics and tendency distribution of smoking and non-smoking among patients with ACHD. Results There were 38,805 ACHD events reported in Tianjin during 2010-2014, with the average crude incidence rate being 77.76/100,000. Male patients (n=24,343) were more than females ones (n=14,462); moreover, and the average age of disease onset was younger in males than in females, showing a statistically significant difference (t=54.31, P=0.00). Among the ACHD events occurred in Tianjin, patients with acute myocardial infarction accounted for 96.6% of the total cases. The prevalence rate of smoking was higher in patients with acute myocardial infarction (males: 55%, females: 22.8%) than in patients with sudden coronary death (males: 43.4%, females: 12.3%), with statistically significant differences (males: χ2=48.96,P=0.00; females: χ2=52.43,P=0.00). Among the male patients with sudden coronary death and male patients with acute myocardial infarction, the smoking rates showed a downward trend with the increase of age, and the difference was statistically significant (χ2=46.56, P=0.00). Among the female patients with the above-mentioned two diseases, the smoking rates reached the highest in the age groups of >69-79 and >59-69 years respectively, and then declined, only showing a statistically significant difference in patients with acute myocardial infarction (χ2=112.76, P=0.00). The smoking rate of male patients showed a general decreasing tendency during 2010-2014, only with a statistically significant difference in patients with sudden coronary death (χ2=29.22, P=0.00). But the smoking rate of female patients showed an overall upward trend (χ2=10.73, P=0.00). Conclusions The number of ACHD cases and its incidence rate increase year by year, and it is an important disease seriously endangering the health of residents. And the smoking rate of ACHD patients is high, especially the group aged < 60 years, which is the major cause for the younger tendency in morbidity age of ACHD patients. Therefore, it is necessary to timely conduct interventions so as to reduce the smoking rate and increase the rate of smoking cessation; meanwhile, propaganda about tobacco control should be further conducted among the females in order to decline the occurrence of smoking-related diseases.
