ABSTRACT
Objective: To analyze the epidemiological characteristics and trends of acute myocardial infarction (AMI) among the elderly in Tianjin from 2011 to 2022, and to provide a scientific basis for assessing the burden of cardiovascular disease and making prevention and control decisions. Methods: The data were collected by the disease surveillance system covering the whole city of Tianjin from 2011 to 2022. Crude and standardized incidence rates were used to describe the incidence of AMI, and Joinpoint regression was used to analyze trends in gender, urban- and rural- and age-specific incidence. The contribution of population aging to the rise of AMI incidence was evaluated by the differential decomposition method. Results: From 2011 to 2022, a total of 77 626 cases of AMI were reported among the elderly in Tianjin (an average of 6 469 cases per year). The crude and standardized incidence rates of AMI in the elderly population in Tianjin showed an upward trend with younger age (P<0.001), and the incidence of male, female, urban, rural, 65-79 years old, and ≥80 years old elderly showed an upward trend (P<0.001). The rising speed in rural areas was higher than that in urban areas (P<0.001). The results of the differential decomposition method showed that the population aging factor's contribution increased from 11.84% in 2012 to 21.56% in 2022. Conclusions: The aging situation in Tianjin is serious. The incidence of AMI in the elderly population is on the rise, and the incidence of AMI in the elderly aged 65-79 is relatively high. Male and rural residents are the high-risk groups. Accurate treatment, intervention, and care measures should be implemented based on the characteristics of the elderly to reduce the burden of chronic diseases.
