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

Count (a) number of deaths where ‘acute coronary heart disease’ (International Classification of Diseases 10th Revision (ICD-10) codes I20–I24) is the underlying cause of death in each calendar year (based on year of registration of death).

Count (b) number of non-fatal hospitalisations where ‘acute myocardial infarction’ (ICD-10-AM I21) or ‘unstable angina’ (ICD-10-AM I20.0) is the principal diagnosis, and separation mode was not ‘died’ or ‘transferred to another acute hospital’, and care type is 'acute care' in each calendar year (based on discharge date from hospital).

The number of acute coronary events is estimated by (a) + (b).

Presented as a number per 100,000 population.

100,000 x (Numerator ÷ Denominator)

Sum of count a (the number of deaths recorded with an underlying cause of acute coronary heart disease) and count b (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) for ages 25 years and over.

Total population aged 25 years and over for calendar year in question.

2007 to 2018—Nationally by:

• Age group (25–34, 35–44, 45–54, 55–64, 65–74, 75–84, 85+) and sex.

2007 to 2017—State/territory of usual residence.

Most recent data available for 2020 Australian Health Performance Framework: 2018.

Compilation of calendar year data from the Admitted patient care NMDS requires data from 2 financial years (e.g. 2018 calendar year data uses Admitted patient care NMDSs for 2017–18 and 2018–19). Numerator, denominator and disaggregation data elements for previous financial years are similar to those listed above for the Admitted patient care NMDS 2017–18 (noting that some codes and classifications may change over time).

This is an estimate of the incidence 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. Validation of reporting of incidence of acute coronary events by Primary Health Networks (PHNs) is currently underway.
