Abstract: Objective: To estimate the prevalence of heart failure with preserved systolic function (HFPSF) in the Aboriginal and Torres Strait Islander population in Far North Queensland. Design: Analysis of the transthoracic echocardiographs of the ATSI subsection of 323 patients, with symptomatic heart failure, referred to a heart failure rehabilitation programme from 2005-2008. Heart failure with preserved systolic function was defined as symptomatic heart failure with an ejection fraction of ≥ 45%. Results: Of the Aboriginal and Torres Strait Islander subsection, 57% had normal systolic function whereas 38% had systolic dysfunction or mixed diastolic and systolic function. A further 5% had non-diagnostic echocardiographs. Conclusion: Heart failure with preserved systolic function HFPSF is highly prevalent in the Aboriginal and Torres Strait Islander community and is at the upper end of estimated prevalence in international studies. Most likely, HFPSF is more prevalent in the Aboriginal and Torres Strait Islander population than in their non-Indigenous counterparts due to the former's higher prevalence of predisposing comorbidities. Further research is needed to compare Aboriginal and Torres Strait Islander data with non-Indigenous Australians, to monitor the evolving course of both systolic and diastolic abnormalities in this subset and to assess whether a separate therapeutic approach should be adopted towards the Aboriginal and Torres Strait Islander population.
