To explore the epidemiological characteristics,
trends and relevant factors of pre-
hospital mortality due to acute
myocardial infarction (AMI) from 1999 to 2016 in Tianjin city, based on
mortality surveillance information and
household registration
population information. Standardized
mortality rates were calculated using the year 2000 world
standard population. From 1999 to 2016, the
research result showed that the pre-
hospital crude mortality rates of AMI were 39.47/100 000 to 90.64/100 000 and the standardized
mortality rates were 30.92/100 000 to 53.90/100 000. The proportion of pre-
hospital AMI deaths was 73.96%-81.92% (t=1.09, P>0.05) within the same period.
Aged,
female, rural residents,
unmarried,
divorced,
widowed, low
education level, and outdoor
workers have a relative higher proportion of pre-
hospital AMI
mortality.
