Objective To evaluate the trends of incidence and mortality of acute myocardial infarction (AMI) in rural residents. Methods A retrospective survey of hospitalization and deaths of AMI from 1976 to 1995 was conducted. Statistical analysis and comparison were performed every five years. Results Compared with stage 1, the number of hospitalized AMI in rural areas increased by 264.6%, the number of deaths increased by 129.4%, the inpatient mortality rate decreased by 37.2%, and the increase in the number of hospitalized women was significantly higher than that of men, 375.0% and 207.4 respectively. % (Chi-square test, P<0.05); Female in-hospital mortality was also higher than that of men, with 19.8% and 13.6%, respectively (chi-square test, P<0.05). Conclusion The morbidity and mortality rate of AMI in rural residents both showed an upward trend, and the hospital mortality rate showed a downward trend.
