Abstract

The nitric oxide (NO) synthesised by blood vessels plays a central role in cardiovascular physiology and pathology, but its bioactivity in vivo is hard to assess. We have recently shown that NO alters the characteristics of the peripheral pulse; this phenomenon promises to form the basis of a simple, novel and non-invasive method of assessment. We will determine whether the phenomenon is as specific to NO as indicated by previous studies, we will characterise the mechanisms underlying it (particularly the role of wave reflections in arteries, using techniques adapted from gas dynamics), and will develop protocols for manipulating NO synthesis in vivo which would allow changes in NO pathway to be characterised. The work, if successful, would have a major impact on cardiovascular research employing experimental animals and could have substantial clinical benefit.
