Trend on mortality/incidence ratio of acute myocardial infarction in Tianjin from 2007 to 2015 / 中华流行病学杂志

ABSTRACT

Objective To explore the variation for mortality/incidence (MI) ratio on acute myocardial infarction (AMI) in Tianjin from 2007 to 2015.Methods Data from both disease and death surveillance systems on AMI in Tianjin from 2007 to 2015,were collected.Incidence and mortality for AMI of people over 35 years old were calculated and fitted by using the exponential model.Annual MI ratios by gender and different age groups were calculated.Join-point regression was used for sensitivity analysis of the ratio.Results Other than 2007,2010,2014 and 2015,the ratios in rest of the years were all bigger than one.From 2007 to 2015,the ratios were ranging from 0.80 to 1.60,with 0.90 to 1.80 for females,and 0.80 to 1.40 for males,respectively.Conclusion The MI ratio on AMI changed relatively stable in Tianjin from 2007 to 2015,but the AMI incidence data in Tianjin seemed underreported,especially for people over 75 years old,indicating that some elderly AMI cases were not reported to the disease surveillance system.
