Heart failure (HF) describes where the heart cannot pump adequately to meet the bodyÍs needs. Mortality remains high; therefore, there is an urgent need for new treatment approaches. The present grant aims to: (1) evaluate treatments for patients at high-risk for future development of HF (2) examine the ability to safely withdraw unnecessary HF drugs (3) focus on the effect of HF on the kidney via novel treatment strategies (4) examine the emerging role of cancer drugs in development of HF.
Research Fellowship: Protection Of Myocardial Function In Health And Disease
Funder

Funding Amount
$631,010.00
Summary
Heart failure (HF) is a major cause of death in Australia. A/Prof Rebecca Ritchie heads Heart Failure Pharmacology at Baker IDI. Her research focuses on new drug strategies to maintain heart function in response to diabetes & heart attack, common precursors of HF. Many of the treatments discovered from this work are naturally-occurring antioxidants; enhancing their activity will ultimately reduce progression to HF & death in the >3 million Australians affected by these disorders.
Oxidative Processes In Vascular Health And Disease

Summary
The process that turns cut fruit brown when it is exposed to air is thought to cause disease of our blood vessels and heart as we age. Despite what we first thought, 'blocking' this oxidation process with antioxidant supplements does not lower heart disease. This is because oxidation not only causes harm but also is useful and essential for normal body function. Our research program aims to show which oxidative processes are needed for blood vessel health or cause vessel disease.
Pathophysiology And Treatment Of Malaria In Our Region

Funding Amount
$951,005.00
Summary
Malaria continues to kill 420,000 people/year. I will lead a team of clinical scientists in identifying how each of the different malaria parasites cause damage to small blood vessels, kidneys and other organs, and will test whether two different drugs can improve these processes and reduce illness. Many of my previous research findings have changed malaria treatment in Australia and across SE Asia, and, where appropriate, I will use new research findings to improve treatments.
Improving Outcomes In Heart Failure Through Basic, Clinical And Translational Research

Funding Amount
$951,005.00
Summary
Heart failure (HF) is a common, chronic cardiovascular condition characterised by a reduced capacity of the heart to function. Patients with HF have a poor quality of life and significantly reduced survival. My proposed programme of research will improve the understanding of heart failure (HF) and lead to better treatments.
Personalised Exercise As Medicine. Optimising The Prescription To Maximise The Benefit

Funding Amount
$772,490.00
Summary
Humans have never been less physically active than in contemporary Western society. These studies will provide an evidence-basis to address the inactivity epidemic by laying the foundation for personalised and effective exercise prescriptions, to which people are more likely to adhere.
Sun Exposure, Vitamin D And Photohealth Over The Lifetime
Funder
National Health and Medical Research Council
Funding Amount
$622,655.00
Summary
Australia is a sunny country with a diverse population. Inappropriate sun exposure for skin type leads to skin cancer (mainly in the fair-skinned) and vitamin D deficiency (particularly in the darker-skinned). Potential benefits of sun exposure are broader than vitamin D production, but remain ill-defined. There are few data on appropriate sun exposure for children. This research fellowship builds the evidence to guide sun exposure messages.
Stress and obesity can lead to high blood pressure and greatly increase the risk of life threatening cardiovascular events. This application seeks to determine which chemicals and parts of the brain are responsible for amplifying the responses to repeated stress and during obesity in animal models leading to hypertension.
Nox Isoforms And Chemokine Receptors As Therapeutic Targets In Vascular Disease And Stroke

Funding Amount

Summary
I am a pharmacologist (a scientist who studies drugs and how they work) trying to find new drugs to treat heart attacks and strokes. I seek to understand the pathways that cause white blood cells and free radicals to accumulate in the walls of arteries in patients with high blood pressure and high cholesterol, and in the brain after stroke. I will then test whether these pathways can be blocked with novel chemical compounds that may eventually be developed into drugs suitable for use in humans.
