Cardiovascular disease accounts for 1/3 of all deaths and more than $22 billion healthcare-related cost in Canada every year. The proposed research project will make significant contribution in improving clinical care by the potential of ITF in detection and diagnostics of cardiovascular disease. In fact, the proposed research project is a key initial step towards our long-term research objective of non-invasive cardiovascular disease diagnostics. The success of the proposed research project will demonstrate that ITF can serve as a low-cost, non-invasive and convenient alternative for central aortic BP measurement, which can further be used for the development of detection and diagnostics methods for a number of cardiovascular diseases (e.g. aortic valve impairment and peripheral arterial disease) by virtue of the relevant health and disease conditions of central and peripheral arterial vessels that ITF can deliver.
