High temperature and cardiovascular disease in Australia under different climatic, demographic, and adaptive scenarios
Authors' conclusion
Higher temperatures are expected to exacerbate the burden of CVD.
Study context
- Population
- Australian population, cardiovascular disease (CVD) burden (DALYs) from the Australian Burden of Disease database, baseline 2003–18
- Outcome
- CVD burden (DALYs) attributable to high temperatures
- Follow-up
- Baseline 2003-18; projections for the 2030s and 2050s
Methodological detailsmeta-regression, climate projection (RCP4.5 and RCP8.5)
- Meta-regression
- Climate projection (RCP4.5 and RCP8.5)
Main finding
As reported in the abstract
CVD burden attributable to high temperatures · baseline 2003-18
Share of CVD burden attributable to high temperatures
7.3%
95% CI 7.0%–7.6%
Attributable DALYs per 100 000 population
223.8
95% CI 221.0–226.6
Further findings
Projected CVD burden attributable to high temperatures · 2030s and 2050s
- Steady increase in CVD burden across all scenarios
- By the 2050s under RCP8.5 with population growth and no adaptation, total attributable burden projected to more than double vs baseline; largest increase in the Northern Territory
- Impacts could be mitigated with effective human adaptation
