Summary
Heart disease is a leading cause of death and disability in Australia. Conditions resulting in reduced blood flow to the heart are particularly common and dangerous. Despite significant progress, we still do not understand exactly how changes in heart function and the aorta (the major artery arising from the heart) affect blood flow to the heart. This study will utilise sophisticated new techniques to look at the interactions between heart function, pressure in the aorta and coronary blood flow
Development Of A Novel Endovascular Therapy For Occlusive Peripheral Vascular Disease

Funding Amount
$624,197.00
Summary
We aim to develop and assess a new medical device for the treatment of diseased arteries. The new device uses an angioplasty balloon coated with a new drug to open narrowed arteries and will enable the arteries to remain open for longer periods and with less likelihood of unwanted side effects from the procedure.
Minimal Structural Strength Required In Endoluminal Devices For Aortic Aneurysms: Mechanisms Of Rupture When They Fail.

Summary
Aneurysmal disease is an age related phenomenon. The mean life expectancy of western populations has doubled in the last 100 years mainly because of the reduction in deaths from occlusive cardiovascular disease. Aneurysmal disease has emerged as a result of the changing pattern of diseases in the community. The impact of this work would be to improve minimally invasive, effective prophylaxis against aneurysm of the abdominal aorta since 80% of those that rupture will result in death.

The mean life expectancy of western populations has doubled in the last 100 years mainly because of the reduction in deaths from occlusive cardiovascular disease. Aneurysmal disease has emerged as a result of the changing pattern of diseases in the community. The impact of this work would be to improve minimally invasive, effective prophylaxis against aneurysm of the abdominal aorta since 80% of those that rupture will result in death. Endoluminal grafting provides a much less invasive procedure and provides an attractive and elegant alternative to open surgery. The general drive in this field is towards miniaturisation. The danger is that structural strengths will be compromised with early failures due to lack of strength; and late failures due to inadequate device durability. This application proposes the development of a collaborative venture with the Department of Vascular Surgery, Royal Perth Hospital, Cook R and D (WA), the Advanced Fluid Dynamics Laboratory (CSIRO, Melbourne) and Centre for Health Services Research (University of WA) to investigate the dynamic flow forces involved in aneurysms of the abdominal aorta. It combines together expertise and facilities to examine the forces acting upon endoluminal stent grafts in pulsatile high pressure environments, the impact on the design, patency, effectiveness and longer-term outcomes. The multidisciplinary team provides a comprehensive approach for this developing area of high technology surgery throughout Australia and internationally. The benefits of this study will directly influence the design and durability of the next generation of endoluminal devices and percutaneous insertions. While Australia is at the forefront of development, its current place in the market can only be maintained by further product development.Read moreRead less
Pharmacological Effects Of Oral L-citrulline And Tetrahydrobiopterin In Patients With Peripheral Artery Disease

Summary
Citrulline, named after citrullus vulgaris, the watermelon, is a precursor of arginine. Arginine is converted to protective nitric oxide (NO), which is decreased in cardiovascular diseases (CVD). Although arginine supplementation can increase NO availability and improve vascular function it is hampered by a low availability. In contrast, Citrulline is highly available and converted to Arginine. Therefore, this project will explore the therapeutic effects of Citrulline in patients with CVD.
The Incidence And Predictors Of Foot Disease Hospitalisation

Summary
Foot disease seems to be a much larger cause of hospitalisation than first thought. This research program aims to study for the first ever time the annual incidence of foot disease hospitalisation and develop models to predict which patients with foot disease are likely to be hospitalised or die. We believe this research will help clinicians, researchers and governments from around the world to measure, predict and prevent foot disease hospitalisation in their nations for the first time.
