Tables 22a and 22b show that in 2010–12 the total cardiovascular disease mortality rate among Māori was more than twice as high as that among non-Māori (RR 2.17, CI 2.08–2.26). In 2012–14, Māori were more than 1.5 times as likely as non-Māori to be hospitalised for cardiovascular disease (RR 1.64, CI 1.61–1.67).

In the equivalent time periods, the stroke mortality rate among Māori were about 1.5 times as high as that of non-Māori (RR 1.56, CI 1.41–1.73), and the stroke hospitalisation rate among Māori were more than 1.5 times as high as that of non-Māori (RR 1.76, CI 1.67–1.86). The disparity was greater for females: the stroke hospitalisation rate among Māori females was more than twice as high as that among non-Māori females (RR 2.17, CI 2.02–2.34).

The heart failure mortality rate among Māori was more than twice as high as that of non-Māori (RR 2.36, CI 1.76–3.17), and Māori were about 4 times as likely as non-Māori to be hospitalised for heart failure (RR 4.01, CI 3.83–4.21). The disparity was greater for females: the heart failure hospitalisation rate among Māori females was about 4.5 times as high as that among non-Māori females (RR 4.49, CI 4.16–4.85).

The rheumatic heart disease mortality rate among Māori was over 5 times as high as that of non-Māori (RR 5.23, CI 3.99–6.87), and the rheumatic heart disease hospitalisation rate among Māori was almost 5 times as high as that of non-Māori (RR 4.82, CI 4.23–5.51). The disparity was greater for females: the rheumatic heart disease hospitalisation rate among Māori females was more than 5 times as high as that among non-Māori females (RR 5.30, CI 4.47–6.29).

Ischaemic heart disease accounts for over half of all cardiovascular disease mortality. Tables 23a and 23b shows that the ischaemic heart disease mortality rate among Māori was more than twice as high as that among non-Māori (RR 2.14, CI 2.02–2.27), and Māori were 1.3 times as likely as non-Māori to be hospitalised for ischaemic heart disease (RR 1.31, CI 1.26–1.36). The disparity was greater for females: the ischaemic heart disease hospitalisation rate among Māori females was almost twice as high as that among non-Māori females (RR 1.83, CI 1.73–1.94).

Māori were significantly more likely than non-Māori to have experienced a re‑vascularisation heart disease procedure (coronary artery bypass graft (CABG) and angioplasty) (RR 1.19, CI 1.04–1.36). The disparity was greater for females: the CABG and angioplasty procedure rate among Māori females was almost twice as high as that among non-Māori females (RR 1.99, CI 1.55–2.57).

The risk of ischaemic heart disease and cardiovascular disease (mortality and hospitalisation) was higher among males than females. The relative differences were greater between Māori and non-Māori females than between Māori and non-Māori males.
