A pressure pulse may be felt at the wrist with every heart beat. New technology allows the analysis of this pulse and provides information that may help doctors make decisions about a patients risk related to blood pressure as well as the effect of drug treatment. The research aims to determine the clinical significance of pressure pulse analysis at rest and during light exercise. It is expected that the new technology will improve the way people with high blood pressure are treated.
AusCAN Risk Assessment For Sitting Acquired Pressure Ulcers
Funder
National Health and Medical Research Council
Funding Amount
$1,707,297.00
Summary
Sitting acquired pressure ulcers are one of the major complications that occur after spinal cord injury. This project will determine factors that are associated with the development of sitting acquired pressure ulcers after spinal cord injury; and will develop a risk assessment tool that can identify those at high risk of pressure ulcer development. The cost of treating a pressure ulcer will also be assessed. This will enable cost-effective preventive treatment to be used in these individuals.
Ultrasonic Blood Pressure Measurement On Implanted Biomedical Surfaces
Funder
National Health and Medical Research Council
Funding Amount
$170,250.00
Summary
The project would develop a prototype device reporting blood pressure on a biomedical implant surface. The device would extract data in real time from a standard ultrasound scanner that images the implant. The School of Mathematical Sciences at Monash University will be contracted to develop this ultrasound pressure sensor.
Renal AT2R Are A Therapeutic Target For The Treatment Of Hypertension In Women

Summary
Being female is associated with better renal function, resistenace to renal injury and hypertension, but it is not understood why. Our work demonstrates that women have more angiotensin type 2 receptors (AT2R) in the kidney then men. In men AT2R have been suggested to protect against hypertension and renal damage. We predict that the effects of AT2R stimulation will be greater in women and therefore the protective benefits greater.
How Does The Central Respiratory Generator Amplify Sympathetic Activity In Hypertension?

Summary
High blood pressure causes many life-threatening cardiovascular diseases, including heart failure and stroke. The cause of most high blood pressure is not known. Using an animal model of high blood pressure we have shown that an interaction, in the brain, between the nerve pathways that generate respiratory activity and regulate blood pressure is altered. This occurs early in life and our evidence strongly suggests this may be a cause of high blood pressure.
Respiratory Modulation Of RVLM Premotor Neurons: Role In The Sympathetic Over-activity Of Hypertension.

Summary
Hypertension is a common health disorder in all societies and is a major risk factor for the development of life threatening cardiovascular diseases, including heart failure and stroke. Whilst some effective therapies are available, many patients are not adequately treated or have reduced quality of life due to serious side effects. There is a great need for alternative therapies.

Whilst some effective therapies are available, many patients are not adequately treated or have reduced quality of life due to serious side effects. There is a great need for alternative therapies. The central nervous system is clearly involved in hypertension although the level of that involvement is not well understood- i.e. is it a causal factor or just a contributor to the maintenance of established hypertension? The experiments outlined in this application are based on the observation that modulation of nervous activity to blood vessels is more influenced by the respiratory system in people with high blood pressure, than in normotensive people. We aim to test whether this increased respiratory modulation might be involved in the generation of the high blood pressure.Read moreRead less
