Death rates from coronary heart disease (CHD) have been declining in
Australia and New Zealand for 20 years. Data from the three MONICA Project
Centres in Newcastle (Australia), Perth (Australia), and Auckland (New
Zealand) show similar trends for fatal CHD but differing trends for
non-fatal myocardial infarction (MI). In Auckland, there has been a
consistent decline in out-of-hospital death rates but no decline in
non-fatal MI rates. In Perth, the greater contribution to the overall
decline has been from out-of-hospital deaths, but in-hospital death rates
and non-fatal MI rates have also declined. There is also some evidence of
an increase in survival following MI in Perth. In Newcastle, both death
rates and non-fatal MI rates have declined. The limited data available
suggest that at least one-half of the decline in mortality can be
attributed to improvements in population risk-factor levels. Improvements
in medical management of both risk factors and established disease are also
making contributions to the decline.
