Total cardiovascular disease mortality was more than two-and-a-half times higher for Māori than for non-Māori (RR 2.8, CI 2.7–2.9). Māori were twice as likely to be hospitalised for cardiovascular disease than non-Māori (RR 2.0, CI 2.0–2.0).

Stroke mortality was nearly twice as high in Māori than in non-Māori (RR 1.9, CI 1.7–2.1), and the stroke hospitalisation rate for Māori was twice that of non-Māori (RR 2.0, CI 1.9–2.1).

The heart failure mortality rate for Māori was almost three times the rate for non-Māori (RR 2.9, CI 2.2–3.8). Māori were five-and-a-half times more likely to be hospitalised for heart failure than non-Māori (RR 5.6, CI 5.4– 5.8).

Rheumatic heart disease mortality was more than eight-and-a-half times higher in Māori than in non-Māori (RR 8.8, CI 7.2–10.8), and the rheumatic heart disease hospitalisation rate was six times higher in Māori than in non-Māori (RR 6.2, CI 5.5–6.9).

The prevalence of heart disease among Māori was one-and-a-half times that in non-Māori (RR 1.5, CI 1.2–1.8).

Among Māori, the ischaemic heart disease mortality rate was more than two-and-a-half times the non-Māori rate (RR 2.8, CI 2.6–2.9), and Māori were one-and-a-half times more likely to be hospitalised for ischaemic heart disease than non-Māori (RR 1.5, CI 1.5–1.6). The disparity was greater for Māori females, who had twice the rate of non-Māori females (RR 2.1, CI 2.0–2.2).

Despite the above, there was no significant difference between the rates of re-vascularisation procedures for Māori and non-Māori (RR 1.0, CI 1.0–1.1). Thus it appears that relative to need (assessed by mortality and hospitalisation for ischaemic heart disease), there is a difference in access to interventions for ischaemic heart disease for Māori compared to non-Māori.

Although risk of ischaemic heart disease and cardiovascular disease was higher among males, relative inequalities were greater between Māori and non-Māori females than among males.
