This study will be testing two devices which are designed to detect cardiovascular disease in patients as early as possible. As there are now many therapies to prevent and treat this condition it is believed that detecting it early will help reduce the burden of the disease and permit more effective treatment.

The two devices the investigators are testing are the ViScope developed by HD Medical and a device developed by CSIRO. Both of these devices are simple, non-invasive and may provide useful information on how well the heart contracts and relaxes as well as valve function of the heart.

The investigators are planning to enroll 100 healthy subjects, 100 participants with risk factors for heart failure and 300 patients with varying types of heart failure.

The data collected from the experimental devices will be compared to the results from standard tests.

Patients will not have any of their therapies altered as part of this study.

Primary Outcome Measures:
  • To validate the diagnostic ability of the two devices against echo and clinical data as the "gold standard". [ Time Frame: Day 1 (study day) ]
    We will construct received operative characteristic (Roc) curves for sensitivity and specificity of the HD Medical ViScope and the CSIRO back scatter analysis device in detecting heart failure using echocardiogram and clinical data as the "gold standard".

Secondary Outcome Measures:
  • Correlation of the devices with standard tests such as BP, HR and BNP. [ Time Frame: Day 1 (study day) ]
    • Correlation of device values with echocardiogram parameters of systolic and diastolic function.
    • Correlation of device values with BNP levels.
    • Correlation of device values with heart rate variability measurements.
    • Correlation of device values with pulse wave velocity and systemic arterial compliance assessment measures.
