Summary
Heart failure (HF) is a common, debilitating and expensive disease; prognosis remains poorer than for the most cancers. 30,000 Australians are diagnosed every year and 300,000 live with the HF, at an annual cost of ~$1Billion. Exercise training is effective therapy in HF, because it reverses many of the problems that contribute to the reduced lifespan and impaired quality of life of patients with HF. We will test an exciting new type of exercise that promising greater benefit, at lower risk.

Summary
The S100A1 protein is one of the most abundant proteins in human heart muscle cells. It binds calcium ions and may play a role in the regulation of heart function. S100A1 levels are reduced in human heart failure, but it is unclear whether this reduction contributes to worsening of the disease. To study this, we have generated a genetically modified mouse strain that cannot make the S100A1 protein. We will use these mice to study how important the protein is for heart function under normal condi ....The S100A1 protein is one of the most abundant proteins in human heart muscle cells. It binds calcium ions and may play a role in the regulation of heart function. S100A1 levels are reduced in human heart failure, but it is unclear whether this reduction contributes to worsening of the disease. To study this, we have generated a genetically modified mouse strain that cannot make the S100A1 protein. We will use these mice to study how important the protein is for heart function under normal conditions, and how it contributes to the development of heart failure. Preliminary data indicate that adult mice with reduced S100A1 protein levels develop a form of heart disease that significantly reduces the efficiency of the pump function of the heart.Read moreRead less
CAMERA-MRI II: Catheter Ablation Versus Medical Rate Control In Atrial Fibrillation With Systolic Heart Failure And Myocardial Fibrosis - An MRI Guided Multi-Centre Randomised Controlled Trial

Summary
Atrial fibrillation (AF) is an irregular heart rhythm commonly seen in patients with a weakened heart muscle. Symptoms and heart function may improve if the rhythm is restored through a catheter ablation procedure. This study will assess whether this procedure improves the function of the heart in those with AF where there is weakness and scarring of the heart. We hope to better determine which patients are best suited and will derive the most benefit from this procedure.
Targeting A New Regulator Of Cardiac Pathology To Protect The Heart From Cardiac Dysfunction And Arrhythmia

Summary
Heart failure is associated with high mortality, and treatment of this condition represents a major unmet need. We recently reported that specific lipid species are elevated in hearts of mice with heart failure. The goal of this study is to comprehensively examine the therapeutic potential of targeting these lipid species with drugs.

Its management consumes health resources and strains sufferers, families and institutions. The proposed monitoring-management device, chronically implanted by minimally invasive surgery, will track the heart’s pumping pattern. It will allow informed decisions to optimise therapy, thereby improving Quality of Life (QOL), decreasing hospitalisations and decreasing healthcare costs. We aim to develop a small, chronically and easily implantable device to track changes in heart function in HF patients.Read moreRead less
