[Changes in the fatality rate of hospitalized in patients with acute myocardial infarction in Bejing from 1977 to 1986].
A study was taken in patients with acute myocardial infarction admitted to a collaborative group (31) hospitals in Beijing in a ten years' period (1977-1986) to observe the changes in mortality. The hospital fatality rate showed no significant difference between 1977-1981 12.3% and 1982-1988 12.1% although the aged cases increased from 51.5% to 53.8% and the reinfarction cases increased from 14.5% to 16.3% in the later five years. Among the causes contributing to death, cardiac arrest decreased from 38.4% to 29.9% while pump failure increased from 38.4% to 46.6%. Death within 24 hours after the onset decreased from 23.8% to 18.8%. The above data showed that since the remarkable decline in mortality of AMI in the early seventies mainly due to the establishment of CCU and better control of arrhythmia. There was no further decline in death in the recent 10 years. Pump failure became a more important cause of death. It seems likely that some interventional treatments should be considered and might be helpful.
