Brief description According to recent statistics, heart failure accounts for almost 300 deaths each year in Australia. In fact, heart failure is now a major health problem that is on the rise, despite the reduced incidence of other forms of heart and blood vessel disease. We are now in the situation where the cost of treatment of heart failure exceeds that of treating all cancer patients, and there are more patient days in hospital with heart failure than with any other heart or blood vessel disease. Most often, the heart fails to act as an effective pump following long-term exposure to high blood pressure. The increased work load placed on the heart effectively forces it to increase in size in a process called cardiac hypertrophy. But this initial compensation which is of benefit to the patient commonly deteriorates and many of the heart cells die. The resulting death of heart cells is the failure of the heart, and death of the patient is inevitable. The fundamental changes in the functional protein molecules of the heart cells that accompany hypertrophy and heart failure are likely to be extremely complex. As yet, no research has taken a global and unbiased look into this complexity. However, there are new technologies that allow us to take such a look. We have established a collaborative research team to investigate the fundamental mechanisms underlying cardiac hypertrophy. We are exploiting a novel model in which hypertrophy does not progress to failure. Our combined expertise allows us to use recently developed scientific methodologies to evaluate the biochemical basis for these events in the heart. We have chosen to focus on documenting the changes in proteins that accompany cardiac hypertrophy with the aim to establish important targets for interventions to permit cardiac cells to survive despite hypertrophy. This will have important implications for preventing cardiac failure.
