Biochemistry And Functional Significance Of Glycosylation Of Apolipoprotein E

Summary
Apolipoprotein E (apoE) is an important molecule which affects our risk of atherosclerosis- coronary disease and of Alzheimer's disease. We know that apoE's functions are very much affected by its structure. One aspect of tis structure which has been neglected is the attachment of sugar molecules . These are very likely to regulate how apoE interacts with other molecules, with cells, and is metabolised in the body and will be investigated in this project.
Long-term Surgical And Socioeconomic Outcomes Following Aortopulmonary Septal Defect Repair In Children

$89,197.00
Summary
About 2% of heart defects are due to communication between the 2 main arteries exiting the heart (truncus arteriosus and aortopulmonary window). If untreated, up to 30% of children die in the first year of life. With surgery many patients are now surviving into adulthood. The long-term outcomes are unknown. This study will review all patients with this defect across Australian and New Zealand. Results from this study will allow us to best manage these patients in the short and long-term.
The Access Project - Assessment Of Coronary Artery Disease Using CT Effectively For Stable Symptoms

$754,369.00
Summary
Invasive Coronary Angiography (ICA) provides x-ray visualisation of coronary disease (CAD) that is essential for coronary surgery/balloon angioplasty. However many patients undergo this procedure without requiring these therapies despite the associated severe complications. The ACCESS Project screens patients scheduled for ICA, identifying those unlikely to have CAD and referring them for non-invasive CT angiography. This strategy reduces procedure complications and result in major cost savings.
Evaluating Coronary Stents Using High-resolution Optical Coherence Tomography Imaging In Patients With Coronary Artery Disease

Funding Amount
$217,274.00
Summary
A stent is a device made of metal that is placed inside an artery to prop it. Recently, the applicant introduced into Australia a novel technology to examine these stents once inside the body. This information may help make stents safer for patients
Redefining The Role Of Macrophages In Atherosclerosis: Macrophage Subset Role In Plaque Stability

Summary
Vascular disease is a major cause of death and disability through events such as heart attack and stroke. A blood cell, called a macrophage, plays a major detrimental role. However, we have identified the presence of an alternate form of this cell in vascular disease that we propose may play an opposing, beneficial role. We will thus re-define the role of the macrophage in vascular disease and predict that we will be able to demonstrate an alternate healing role. This will provide a new therapeu ....Vascular disease is a major cause of death and disability through events such as heart attack and stroke.

Y Chromosome Mechanisms In Coronary Artery Disease

Funding Amount
$369,076.00
Summary
The Y chromosome determines sex in men and until recently was not thought to contribute to heart disease. We previously found a specific type of Y chromosome that does contribute to heart disease. In the current project we plan to find the exact gene and mechanism in the search as a therapeutic target.
A Dual Antigen Synthetic Peptide Subunit Vaccine Approach To Prevent Streptococcal Associated Cardiovascular Disease
Funder

Funding Amount
$604,017.00
Summary
Infection with streptococcus is responsible for causing more than 500,000 deaths each year, the majority of which are due to rheumatic fever and rheumatic heart disease, which contributes to cardiovascular disease. Our research is aimed at the development of a vaccine to prevent heart disease and involves targeting multiple molecules present on the bacterial surface. We will use a novel vaccine delivery system developed in the laboratory, which will enable the vaccine to be delivered nasally.
Central Blood Pressure And Cardiovascular Risk In Children Within The General Population And After Repair Of Congenital Heart Disease
Funder
National Health and Medical Research Council
Funding Amount
$431,000.00
Summary
With an exceptional research standing internationally, and as the leader of a Cardiovascular Bioengineering team, I am developing a new method for assessing central blood pressure in children that will provide better information about early risk of cardiovascular disease than arm blood pressure. This will be applied (1) in a large health study of Australian children and (2) to identify risks and causes of adult-type cardiovascular disease in children with repaired congenital heart disease.
Coronary Artery Calcium Score: Use To Guide Management Of Hereditary Coronary Artery Disease (CAUGHT-CAD)
Funder

Funding Amount
$2,762,082.00
Summary
Lifetime risk of coronary artery disease (CAD) is doubled in families with premature CAD. This study will be the first randomized controlled trial of the use of coronary artery calcium scoring (CCS) in relatives of patients with premature CAD, in which treatment will be initiated based on CCS. At three years, the effectiveness of intervention will be assessed on change in plaque volume at CT coronary angiography. The results inform the guidelines regarding evaluation of families with CAD.
