Key result
Urban Australian Aboriginal people had a significantly higher rate of first coronary heart disease events compared to a matched non-Aboriginal population (14.9 vs 2.4 per 1000 PY; IRR 6.1, 95% CI 4.5-8.4).

Signals urgent need for targeted CHD prevention in urban Aboriginal Australians; leaves open causal mechanisms and intervention trials.
Cohort (n=4,495)
Does urban Australian Aboriginal ethnicity increase the risk of first CHD events compared to a matched non-Aboriginal population?
Relative Risk: 6.1 (95% CI 4.5–8.4)
Absolute Event Rate: 14.9% vs 2.4%
Urban Australian Aboriginal people experience a 6-fold higher incidence of first CHD events compared to a matched non-Aboriginal population, with events occurring at much younger ages.
Bradshaw et al. (2010) conducted a cohort in Coronary heart disease (n=4,495). Aboriginal ethnicity vs. Matched non-Aboriginal population was evaluated on First CHD events (hospital admission or CHD death) (IRR 6.1, 95% CI 4.5 to 8.4). Urban Australian Aboriginal people had a significantly higher rate of first coronary heart disease events compared to a matched non-Aboriginal population (14.9 vs 2.4 per 1000 PY; IRR 6.1, 95% CI 4.5-8.4).
