Funding Amount
$92,161.00
Summary
This unique project will examine the heart health of roughly 3500 11-12 year olds in Australia's only nationally-representative children's study. It will then examine factors that may contribute to differing heart disease progression. We will characterise established factors (such as cholesterol, blood pressure and diabetes), as well as measures of infection burden and inflammation to examine the innovative theory that childhood infection and/or its treatment contribute to poorer heart health.

Summary
Heart disease is the leading cause of death and disease globally. The resulting social and economic burden is of growing concern and the demand for efficient care is intensifying. My research aims to implement innovative, scalable and efficient strategies to improve outcomes for people living with heart disease. Specifically, my research will evaluate how text messaging and mobile apps can strengthen patient-level behaviour change and how data can be used to strengthen health service delivery.
An Implementation Trial Of A Telephone-based Care Management Program For Patients Following Myocardial Infarction

Funding Amount
$641,656.00
Summary
We are trialling the implementation of an innovative telephone-delivered program for managing people who have had a heart attack. Cardiac rehabilitation programs are generally based in hospitals in Australia and people have to be able to attend the programs when they are offered. Even though such programs have been shown to be very effective in improving outcomes after a heart attack, at least 85% of Australians after a heart attack are either unable to access and-or unable to attend such progra ....We are trialling the implementation of an innovative telephone-delivered program for managing people who have had a heart attack. Cardiac rehabilitation programs are generally based in hospitals in Australia and people have to be able to attend the programs when they are offered. Even though such programs have been shown to be very effective in improving outcomes after a heart attack, at least 85% of Australians after a heart attack are either unable to access and-or unable to attend such programs due to transport and many other barriers. So, there is an urgent need to identify new, effective, and affordable ways of delivering cardiac rehabilitation programs to people after a heart attack. The proposed telephone-delivered program will be particularly appropriate for disadvantaged people, such as those living in rural and remote areas as well as Indigenous Australians, who do not currently have access to hospital-based cardiac rehabilitation programs. People who have had a heart attack will be recruited from three of Brisbane's largest public teaching hospitals, and will then be randomly assigned to the telephone-delivered cardiac rehabilitation program (Care Management Intervention group) or to a control or Usual Care group. The Care Management Intervention group will receive regular telephone calls from a highly qualified 'Care Manager' based at the renowned National Heart Foundation of Australia telephone support service, 'Heartline'. The Care Manager will help people to manage their heart condition and prevent the reoccurrence of further heart problems. People will also be encouraged to make necessary lifestyle and behavioural changes with the assistance of the Care Manager and some Heart Foundation educational and interactive resources to record their progress. We expect that the program or Care Management Intervention group will have better health outcomes than the control or Usual Care group at 6 and 12 months follow up.Read moreRead less
The Effect Of Moderate And High Intensity Exercise On Cardiovascular Health And Cardiac Remodelling

Summary
Failure of the cerebral circulation to meet the brain's immediate high nutritive requirements results in stroke in just a few minutes. Stroke continues to be a major cause of death and disability, and this major medical challenge requires urgent and significant research at the basic level to better understand mechanisms of normal, and then abnormal, regulation of cerebral artery function.

Stroke continues to be a major cause of death and disability, and this major medical challenge requires urgent and significant research at the basic level to better understand mechanisms of normal, and then abnormal, regulation of cerebral artery function. The project will examine the importance of a novel mechanism in regulating brain blood flow by affecting the degree of opening of the cerebral arteries. This mechanism involves activation of an enzyme, Rho-kinase, which is present in the wall of blood vessels. The applicants believe that this process plays an important role in the normal, healthy regulation of blood supply to the brain. Moreover, there are strong reasons for us to speculate that the function of this enzyme is abnormally high in two disease states that are associated with an increased risk of stroke - high blood pressure and subarachnoid haemorrhage. We will employ a variety of techniques to assess the importance of Rho-kinase in cerebral artery function in the living body, and also in isolated segments of artery. The results are expected to provide major new insight into mechanisms that regulate brain blood flow, and the knowledge gained here may lead to better therapies to prevent or treat stroke.Read moreRead less
Developmental Origins Of Adult Cardiovascular Disease: Vascular Health In The Raine Cohort

National Health and Medical Research Council
Funding Amount
$1,087,427.00
Summary
The Raine study is a unique long term experiment that has collected extensive pre-birth and childhood data in ~3000 young Australians, who are now 27 years old. We plan to measure the artery health of 1200 of these volunteers and to determine what factors, both before and after birth, influence the presence of early atherosclerosis in humans. This study will guide strategies aimed at early prevention of heart attacks and stroke in humans, by defining the major risk factors.
Obesity, Pre-diabetes And Future Risk Of Diabetes: Maximising The Evidence, Minimising The Cost
Funder
National Health and Medical Research Council
Funding Amount
$470,136.00
Summary
The overarching aim of this proposal is to reliably determine how best to identify people at high risk of developing future diabetes. We will do this by using information on biological and behavioural risk factors that was collected on nearly 200,000 people many years ago and who were subsequently followed up to see who developed diabetes. This information will be used to create a risk prediction tool for spotting individuals most at risk of developing diabetes at some point in the future.
Clinical Approaches To Preventing Cardiovascular Disease

Funding Amount
$463,652.00
Summary
Cardiovascular disease (CVD) is the leading cause of death and disease burden globally. While many new treatments have been discovered in the last few decades to prevent CVD, surveys show many people do not receive these treatments. Dr. Chow is committed to using her skills as a cardiologist and a researcher to bridge this gap. Her program aims to identify novel, simple and scalable approaches to decrease the gap in preventative care and reduce the burden of CVD in Australia and beyond.
