What has happened since 2017 ???
What has changed in Australia ???
Let me think......
Coronary heart disease is Australia’s leading cause of death, and although death rates have fallen substantially over recent decades, declines among some age groups appear to have slowed. Trends in coronary heart disease mortality: age groups and populations examines how the decline has varied between young adults, middle-aged and older persons, and among different population groups,

Conclusion

Although the CHD death rate has declined in Australia in recent decades, the average
annual rate of change has varied between age groups and over time. Less favourable trends
have been observed in people aged 25–39, 40–54, and 55–69, with a recent slowing in the
annual average rate of decline. For men and women aged 70 years and over, who are most at
risk of CHD death, mortality declines have continued to improve.
Overall trends in CHD mortality decline are less favourable among the lowest SES group
and among people living in the most remote areas. CHD mortality rates for Indigenous
Australians remain higher than for other Australians, however between 2001–2002 and
2009–2010 there was improvement in the gap, more so for Indigenous women than men.
Unfavourable trends in some key risk factors for CHD are thought to underlie the slowing of
the decline in CHD deaths among younger age groups.
