Determining Current And Future Populations At Risk Of Cardiovascular Disease Using Applied Geographic Information (GIS).

Funding Amount
$332,713.00
Summary
This unique and innovative project has the potential to deliver a powerful tool to both highlight and combat the burden of CVD in Australia. Key outcomes include,the ability to identify geographical ‘hotspots’ where there is likely to be a mismatch between demand for and actual provision of cardiovascular services and where new hotspots are likely to emerge requiring increased resources and services as a result of the ageing and increasing risk factors such as diabetes and obesity.

Summary
This Centre has three objectives: to create clinical research platforms; to provide time and training for advanced cardiology trainees, young clinical academics, research nurses, allied health staff and non-medical science graduates; and to translate previously established local and international research outcomes into knowledge, education and health benefits for the wider Australian community.

Current known risk factors explain approximately half of all cardiovascular diseases. The search for new risk factors is therefore a high priority. Evidence suggests that chronic inflammation is closely involved in the process of atherosclerosis and its clinical complications. This study aims to determine if sensitive serum markers of inflammation and gene-environment interactions that affect inflammation will predict the extent and progression of carotid atherosclerosis in an Aboriginal and a non Aboriginal community population and in patients with premature coronary heart disease. This study should provide a greater understanding of the mechanisms involved in the development and progression of atherosclerosis. It is likely that we will find that some inflammatory markers and candidate gene polymorphisms will help identify individuals at increased cardiovascular risk, and who require earlier treatment to prevent disease. In particular, it would focus on preventive therapies that reduce atherosclerosis through anti-inflammatory targets. This study represents a crucial step towards improving our understanding of the aetiology of cardiovascular diseases, and in developing new ways to prevent heart disease and stroke. Progress in these areas will likely have significant public health benefitsRead moreRead less
Neurogenic Mechanisms Of Cardiovascular Risk In The Metabolic Syndrome: Benefits Of Lifestyle Interventions

Funding Amount
$328,194.00
Summary
One in four adult Australians has the 'metabolic syndrome' (MetS), a clustering of metabolic and heart disease risk factors associated with abdominal obesity. Sympathetic nervous system (SNS) activity is increased in the MetS resulting in enhanced release of the stress hormone 'noradrenaline' . This project will examine the biological and genetic determinants of enhanced SNS activity and the benefits of lifestyle interventions (weight loss, weight loss maintenance and aerobic exercise).

Developmental Stages Of Cardiovascular Risk Factors And Their Public Health Impact: A Life Course Perspective
Funder

Funding Amount
$380,558.00
Summary
Using a life course approach, the aims of this study are to (a) investigate the developmental stages (pre-natal, childhood and adolescence) of cardiovascular (CVD) risk factors in young adulthood; (b) identify what is influencing these developmental stages either directly or indirectly and (c) quantify the public health burden of these stages and individual factors. Findings will enhance our understanding of the developmental stages of CVD and their public health burden.
The Role Of The TGF-b Superfamily Cytokine MIC-1 In The Pathogenesis Of Atherosclerosis

Summary
MIC-1 is a protein first cloned and characterised by our research group. It belongs to the TGF beta protein superfamily which is very important in development, cancer, wound - fracture healing and inflammation. The aim of this project was to start to gain an understanding of the role of this protein, both in normal biological processes (especially pregnancy) and in disease. MIC-1 is present in the blood of all individuals and high levels are associated with an increased risk of heart attacks and ....MIC-1 is a protein first cloned and characterised by our research group. It belongs to the TGF beta protein superfamily which is very important in development, cancer, wound - fracture healing and inflammation. The aim of this project was to start to gain an understanding of the role of this protein, both in normal biological processes (especially pregnancy) and in disease. MIC-1 is present in the blood of all individuals and high levels are associated with an increased risk of heart attacks and strokes. In this study we wish to use animal models, in which the gene for MIC-1 has either been deleted or enhanced, to determine whether MIIC-1 plays a direct role in these diseases.Read moreRead less
Monomeric C-reactive Protein As Pathogenic Factor And Therapeutic Target In Atherothrombotic Disease.

Funding Amount
$674,880.00
Summary
CRP is a plasma marker that can identify individuals at high risk for heart attack and stroke. Our preliminary data suggests that plasma CRP is not only an innocent marker, but can also be activated and thereby become a strong inflammatory stimulus by changing from a five unit to a single unit form on the surface of activated platelets. We will investigate this CRP activation in vitro, in animal models and in patients, and aim to develop new drug therapies for diseases such as heart attack.
Modifying Factors And Phenotype Heterogeneity In Familial Hypertrophic Cardiomyopathy

Summary
Familial Hypertrophic Cardiomyopathy (FHC) is an inherited disorder characterised by abnormal thickening of heart muscle, resulting in clinical symptoms in affected individuals ranging from mild symptoms, to heart failure and sudden death. FHC is the commonest cause of sudden death in individuals aged less than 35 yrs in our community, and is caused by defects in genes (DNA) important in the heart's cellular structure and function. Understanding and identifying the molecular steps involved in ho ....Familial Hypertrophic Cardiomyopathy (FHC) is an inherited disorder characterised by abnormal thickening of heart muscle, resulting in clinical symptoms in affected individuals ranging from mild symptoms, to heart failure and sudden death. FHC is the commonest cause of sudden death in individuals aged less than 35 yrs in our community, and is caused by defects in genes (DNA) important in the heart's cellular structure and function. Understanding and identifying the molecular steps involved in how this defect in our DNA can lead to the clinical features of FHC, is the focus of the research described in this project. A common occurrence in families with FHC is the identification of two affected individuals within the same family (e.g. siblings) and who therefore have the same genetic defect, with variable clinical outcomes. For example, one sibling may have no symptoms and live a normal life, while his-her sibling, may develop severe symptoms, heart failure, and-or early sudden death. The reason for such diversity in clinical features, even amongst individuals with the same genetic defect, most likely reflects secondary modifying factors, e.g. genetic and-or environmental factors which modulate the expression of the primary FHC-causing gene defect. This project will focus on identifying and studying such modifying factors. One aspect of the project will focus on the identification of a genetic modifier which has been shown to exist in a genetically-engineered mouse model of FHC. A second aspect of the proposed research will focus on potential environmental factors, including pharmacological agents which may prevent disease progression, dietary factors, e.g. caffeine intake, and lifestyle factors , e.g. exercise. Through these studies, it is hoped that key molecules and important pathogenic mechanisms will be identified, leading to the development of potentially new therapies, to both treat, and ultimately prevent or cure this inherited cardiac disorder.Read moreRead less
