Computation description:Help on this term

Rates are directly age-standardised to the 2001 Australian population.

The number of acute coronary events is estimated by (a) + (b), where:

(a) = The number of deaths where ‘acute coronary heart disease’ is the underlying cause of death in each calendar year (based on year of registration of death).

  • ‘Acute coronary heart disease’ is defined using codes I20–I24 under the International Classification of Diseases 10th Revision, Australian Modification (ICD-10-AM) 10th and 11th edns.

(b) = The number of non-fatal hospital separations, where:

  • ‘Acute myocardial infarction’ (ICD-10-AM 10th and 11th edn code I21) or ‘unstable angina’ (ICD-10-AM 10th and 11th edn  I20.0) is the principal diagnosis, and
  • Separation mode is not equal to ‘died’ or ‘transferred to another acute hospital’, and
  • Care type is equal to ‘acute care’ in each calendar year (based on discharge date from hospital).

Crude rate: 100,000 x (Numerator ÷ Denominator)

Numerator:Help on this term

Number of deaths recorded with an underlying cause of acute coronary heart disease (a) plus the number of non-fatal hospitalisations with a principal diagnosis of acute myocardial infarction or unstable angina that do not end in death or a transfer to another acute hospital (b). For ages 25 and over.

Comments:Help on this term

Most recent data available for 2022 National Healthcare Agreement performance reporting: 2019.

Compilation of calendar year data from the Admitted patient care NMDS requires data from 2 financial years (e.g. 2019 calendar year data uses Admitted patient care NMDSs for 2018–19 and 2019–20).

This is a measure of the number of acute coronary events in a calendar year. An individual may have more than one event during a year.

This indicator has previously been published at the national level by age and sex.

The data for state/territory (of usual residence) has previously been published. Comparison of acute coronary event rates between jurisdictions should not be made as an AIHW assessment of validity study (based on New South Wales and Western Australia data) has shown that there are variations in the ascertainment of acute coronary events between jurisdictions. This is likely due to differing treatment and referral patterns and data recording practices across states/territories, which are likely to have an impact on administrative records and affect jurisdictional comparability.

Further details on the incidence of heart attacks among Indigenous Australians are available from the Aboriginal and Torres Strait Islander Health Performance Framework (measure 1.05: Circulatory disease).
