title: [The trend of changes in the rate of admission and mortality among rural patients with acute myocardial infarction].
abstract: OBJECTIVE
  To evaluate the trend of changes in the rates of incidence and mortality of acute myocardial infarction (AMI) in rural population.
  
  
  METHODS
  Analysis was made on the clinical data of hospital admission and mortality rate of patients with AMI in rural areas during 1976 and 1995 under every 5 - year interval: 1976 - 1980, 1981 - 1985, 1986 - 1990 and 1991 - 1995.
  
  
  RESULTS
  The number of admission of patients with AMI in rural areas in these four periods were 82, 118, 177 and 299 cases respectively. The number of deaths were 17, 23, 30 and 39 cases and the fatality rates among inpatients were 20.7%, 19.5%, 16.9% and 13.0% respectively during these periods. The number of admission in females increased faster than that in males, the increase in percentage was 375.0% versus 207.4% (P < 0.05). In - patient fatality rate in females was significantly higher than that of males (19.8% vs 13.6%, P < 0.05).
  
  
  CONCLUSIONS
  The rates of incidence and mortality of AMI have increased while inpatient fatality has decreased in rural population in the last 20 years.
