Trends in in-hospital mortality following acute myocardial infarction (AMI) in Victoria, 1987-1994.
Death rates from coronary heart disease have exhibited remarkable declines in most industrialised countries.
Cardiovascular mortality has been the subject of extensive research and we considered it important to analyse recent local population based data on hospital outcomes of acute myocardial infarction (AMI).
To document the trends in in-hospital mortality from AMI in Victoria from 1987-1994.
This was a retrospective analysis of data from the Victorian Inpatient Minimum Database relating to all public acute care hospitals.
All separations recording a principal diagnosis 410 (AMI) were selected.
Changes in distribution of AMI separations, in-hospital mortality, and changes in length of stay were examined.
The mean age of women admitted was 72 years compared with 64 years for men.
Women comprised around a third of the overall sample but the proportion varied from 13% in those under 50 years to 57% among those aged 80 years and over.
A striking decline in mortality was observed throughout the eight year period.
The relative age adjusted decline was 33.5% (40% in males and 26% in females) with rates remaining higher in women.
This decline occurred despite the increasing representation of those aged over 80 years.
There was a significant decline in the mean length of stay (1.8 days) over the eight year period but this is likely to have had only minimal impact on mortality rates. (...)
