A new study shows Maori and Pasifika patients could be missing out on critical heart treatment because of diagnosis methods that are not fit for purpose. The University of Otago paper says the normal range used to guage heart abnormalities have been developed for white Americans. When applied to Maori and Pacific people, this could result in incorrect diagnoses and potentially delay treatment. Nathan Rarere spoke to one of the study's authors, Professor Gillian Whalley.
