The Centre of Research Excellence (CRE) to Reduce Inequality in Heart Disease focuses on improving the heart health and outcomes of groups and communities i.e. Regional Australians, Indigenous Australians and International Health

Overview

RegionalAustralians.jpg - largeAmid improvements in cardiovascular disease (CVD) related mortality, risk factors remain high in adult Australians. Age-adjusted case fatality rates from CVD have fallen from 55% of all deaths in the late 1960s to 34% in 2007 [1]. This is attributable to better CVD prevention, detection and clinical management. Nevertheless, CVD (notably coronary heart disease) ranks second highest in healthy years of life lost, representing 16% of the overall disease burden [1]. Inevitably, the burden of CVD will inexorably rise within Australia’s ageing population [2]. Despite some encouraging trends in respect to the declining prevalence of major risk factors [1, 3], there are equally cautionary data in respect to sustained, and in some cases increasing levels of hypertension [4, 5], dyslipidaemia [1, 6] and metabolic risk factors (e.g. physical inactivity/sedentary behaviour[1] and obesity [3, 7 ]). When coupled with increasing longevity, it is therefore imperative that heart health be improved by mitigating elevated risk factors [8] through pharmacological and/or non-pharmacological recommendations embedded within evidence-based guidelines [9-15].

 

Any focus on reducing cardiovascular risk levels has to consider higher risk populations. People living in regional, rural or remote locations consistently fare worse than their metropolitan counterparts [5, 15,16] with mortality rates rising in accord with remoteness [17]. Unfortunately, reliable (measured) population data, especially for biomedical health risk factors, are over 10 years old and limited in respect to regional data. This extends to the AusDiab Study [18] with specific studies examining those living beyond metropolitan regions few and far between [19,20]. Moreover, the distribution of traditional health care services do not match the needs of regional/rural dwelling Australians [21].

 

Led by Associate Professor Melinda Carrington (supported by an NHMRC of Australia Career Development Award), the CRE to Reduce Inequality is leading a number of projects to achieve the following:

  1. Accurately estimate the burden of risk (including metabolic disorders) and established heart disease in regional Australia;
  2. Develop innovative and cost-effective health care programs to deliver state-of-the art prevention and disease management strategies to reduce cardiac events in regional communities;
  3. Translate these (and other) innovative strategies into sustainable health services to meet the additional needs of those living in Regional Australia.
