Objective To observe the incidence of acute myocardial infavtion (AMI) between 1999 and 2013 in Tianjin residents and analyze the incidence differences on residents with various age,gender and living in urban or rural areas.The data might help for targeted prevention strategies among Tianjin residents.Methods AMI incidence data between 1999 and 2013 were obtained based on Tianjin cardiovascular disease incidence surveillance registry established by the Tianjin Centers for Disease Control and Prevention (CDC).Related information such as permanent residents' population data were obtained from Tianjin Municipal Public Security Bureau.The Chinese population data in 2000 were used for age-sexstandardized rates estimation.Difference between two (or more) independent groups was compared by the Chi Square statistics.The Chi-square test for trend was used for computing the incidence trend in years and ages.Results AMI incidence rate in Tianjin declined from the year 1999 to 2013 with the rude incidence rate of 80.46/100 000 to 81.29/100 000,and with the standardized incidence rate of 64.85/100 000 to 44.57/100 000 (Z =-35.767,P ＜ 0.001).AMI incidence decreased gradually in residents aged over 45 years old (P ＜ 0.01),but increased in residents younger than 45 years old (P ＜ 0.001) from 1999 to 2013.The AMI incidence rate is consistently higher in male residents (rude incidence 99.89/100 000-102.98/100 000,standardized incidence rate 78.53/100 000-56.61/100 000) than in female residents (rude incidence 61.18/100 000-59.44/100 000,standardized incidence rate 50.31/100 000-31.76/100 000,both P ＜ 0.001) and higher in urban residents (rude incidence rate 133.98/100 000-98.02/100 000,standardized incidence rate 99.89/100 000-50.12/100 000) than in rural residents (rude incidence rate 35.57/100 000-66.19/100 000,standardized incidence rate 32.68/100 000-43.51/100 000,Z =6.217,P＜ 0.001).AMI incidence decreased significantly in the urban residents (rude incidence rate 133.98/100 000-98.02/100 000,standardized incidence rate 99.89/100 000-50.12/100 000,Z=-46.968,P＜ 0.001),while significantly increased in rural residents (rude incidence rate 35.57/100 000-66.19/100 000,standardized incidence rate 32.68/100 000-43.51/100 000,Z =6.217,P ＜ 0.001) during the study period.Conclusions The general incidence of AMI decreased during the study period in Tianjin residents.However,AMI incidence significantly increased in young male residents and rural residents.It is necessary to develop corresponding strategies for AMI control for Tianjin residents with different age/gender and living in different areas.
