Summary
The normal function of the body is maintained by naturally occurring compounds. Some for example affect the heart, fine tuning it to make it beat faster or slower, or beat with greater or less force when required in different situations in health and disease. We were the first to show just recently that a small protein which occurs naturally in the body, called urotensin-II can affect the way the heart beats. We showed that extremely tiny amounts increase the force of the heart beat. Our finding ....The normal function of the body is maintained by naturally occurring compounds. Some for example affect the heart, fine tuning it to make it beat faster or slower, or beat with greater or less force when required in different situations in health and disease. We were the first to show just recently that a small protein which occurs naturally in the body, called urotensin-II can affect the way the heart beats. We showed that extremely tiny amounts increase the force of the heart beat. Our findings indicate that urotensin-II is the most potent heart stimulator identified to date. In patients with heart failure, short term stimulation of heart contraction is beneficial, supplying the heart and other organs with vital oxygen and nutrients. However, in the long term excessive stimulation causes worsening of the patients condition. Very little is currently known about the way in which urotensin-II alters heart function. The goal of our study is to understand the mechanism involved in urotensin-II mediated effects on the heart. This will involve identifying the location of urotensin-II and its receptors in the heart, and determining what signalling changes occur after the interaction of urotensin-II with its receptors. Urotensin-II must first be cleaved from a larger drug. We will determine where in the heart this cleavage occurs and whether the process is crucial to the ability of urotensin-II to stimulate contraction of the heart. Since stimulators of heart contraction are detrimental to patients with heart failure in the long term, we will determine whether these patients have more urotensin-II in their blood than patients who do not have heart failure. If the levels of urotensin-II are higher in heart failure patients, it may indicate a need to interfere with the interaction of urotensin-II with its receptors.Read moreRead less
Enhancing Erythropoietin Therapy In Ischaemia-reperfusion Injury Of Heart And Kidney

Funding Amount

Summary
Heart attacks and kidney disease from a lack of blood flow are common causes of morbidity and have poor treatment options. Erythropoietin (epo) is a useful new treatment, but there remain some caveats to its use in humans: eg. it may cause excessive scarring during repair. Use of epo with an anti-inflammatory drug may decrease scarring and provide benefit to long-term health. We plan to carefully define the biomolecular pathways of injury and repair, to better plan this therapy for human use.
CKD-FIX: A Randomised, Controlled Trial Of Allopurinol In The Slowing Of Kidney Disease Progression
Funder
National Health and Medical Research Council
Funding Amount
$1,917,147.00
Summary
Chronic kidney disease (CKD) is a major public health problem affecting over 1.5 million Australians and is associated with increased risk of death, heart disease and progression to end-stage kidney disease (ESKD). Current treatments to slow progression to ESKD are limited. The CKD-FIX trial aims to find out whether treatment with allopurinol, a commonly used drug for gout prevention, safely and effectively slows CKD progression. This could lead to significant health and economic benefits.
Improving Nurse-administered Sedation Practice In The Cardiac Catheterisation Laboratory
Funder
National Health and Medical Research Council
Funding Amount
$320,891.00
Summary
This research will provide evidence to inform nursing management of the potentially life-threatening complications that are associated with the administration of sedation in the cardiac catheterisation laboratory. Three studies will be conducted: an investigation of the prevalence and risk factors of hypothermia after sedation; a randomised controlled trial of active warming to prevent hypothermia; and a study to determine whether audit and feedback improves patient safety during sedation.
Optimising Heart Disease Prevention And Management

National Health and Medical Research Council
Funding Amount
$4,647,175.00
Summary
As we become older and risk factors such as obesity become more common, our biggest contributor to death and disability, cardiovascular disease (including heart disease), will continue to exert an enormous burden on our health care system and society. We will extend our ground-breaking research on multidisciplinary teams to create new and innovative health care programs to optimise the prevention and management of new heart disease and chronic forms of heart disease.
Rapidly giving intravenous fluid to prevent or treat shock (fluid resuscitation) is one of the commonest treatments given to critically ill patients. Current guidelines recommend crystalloid solutions but it is unknown whether any particular crystalloid is better than others. This trial will determine whether the use of one of two crystalloid fluids, saline or PlasmaLyte, reduces the risk of organ injuries, such as kidney failure, and improves patients chances of surviving critically illness.
I-HEART - Implementation Of HEArt Failure Guidelines In Regional AusTralia
Funder
National Health and Medical Research Council
Funding Amount
$1,266,173.00
Summary
Heart failure (HF) is a common disease of the heart with a high rehospitalisation and mortality rate. Regional HF patients rarely receive the full benefits of evidence-based care simply due to inaccessibility to a HF specialist team. This translational project will implement key recommendations from clinical guidelines in regional health services and improve access to specialist services. It has the potential to keep patients out of hospital and save lives.

Funding Amount
$499,797.00
Summary
This research will investigate the impact of ischemic heart disease on the prevalence and severity of patients with depression. This will be done via a 12 month general practice based program of 1) systematic screening for depression 2) informing general practitioners of best-practice guidelines for management of depression in these patients, and 3) providing the treating general practitioner with patient-specific, psychiatric advice.
A Supervised Exercise Programme Following Hospitalisation For Heart Failure: Does It Add To Disease Management?

Funding Amount
$730,966.00
Summary
Congestive heart failure (CHF) is a common, disabling condition. Outcomes are improved by a post-hospital disease management programme (DMP) including education, support and followup from a team of nurses, doctors and other health professionals. This study looks at whether adding a supervised exercise programme to a DMP can reduce death rates and hospital stays, and improve physical function and depression in patients with a recent hospital stay for CHF.
