WebArterial stiffness may also affect the time at which pulse wave reflections return to the heart. As the pulse wave travels through the circulation it undergoes reflection at sites where the transmission properties of the arterial tree change (i.e. sites of impedance mismatch). These reflected waves propagate backwards towards the heart. WebAortic stiffness has been identified as a correlate and potential risk factor to dementia. Extreme aortic stiffness is also linked to microvascular lesions in high-flow organs including the kidney and brain, which suggests that aortic stiffness eventually damages the tiny capillaries in these organs.3
