Summary
Ischaemic heart disease (IHD) mortality rates are significantly higher in northern Tasmania. Regional differences in IHD deaths, particularly in-hospital deaths, warrant further investigation to address high coronary mortality rates.
Area of Science:
- Epidemiology
- Cardiovascular Disease Research
Background:
- Ischaemic heart disease (IHD) poses a significant public health challenge.
- Understanding regional variations in IHD mortality is crucial for targeted interventions.
Purpose of the Study:
- To quantify regional disparities in IHD mortality rates across Tasmania.
- To identify factors contributing to these observed regional differences.
Main Methods:
- A descriptive epidemiological study was conducted.
- Data included male residents of Tasmania aged 30-69 years who died from IHD between 1986 and 1989.
- Coronary deaths were coded by the Australian Bureau of Statistics and validated with hospital and community data.
Main Results:
- Substantial regional differences in coronary death rates were identified within Tasmania.
- The two northern Health Regions exhibited disproportionately high IHD mortality rates compared to national averages.
- Variations in in-hospital deaths significantly contributed to the observed regional disparities.
Conclusions:
- Coronary mortality rates in Tasmania are significantly higher than in other Australian states, driven by elevated rates in the northern regions.
- These regional differences highlight the need for further research into the causes of high IHD mortality in Tasmania.
- The findings underscore the necessity of establishing a dedicated coronary register in Tasmania.
