Pulse wave velocity (PWV) as a function of blood pressure (BP). (a) For a single representative young (left) or old Fisher rat (right), scatter plots of PWV as a function of diastolic, mean and systolic BP are given along with corresponding quadratic fits to that individual animal’s data. (b) Quadratic fits of PWV as a function of diastolic BP for each young (left) and old Fisher rat (right). (c) Quadratic relationships between PWV and diastolic, mean and systolic BP as determined from the data from all young (left) or old Fisher rats (right). (d, left) Quadratic fits of PWV as a function of diastolic BP for all young (solid line, light gray) and old (dashed line, dark gray) Fisher rats, with 95% prediction error bands. (d, right) Quadratic fits of PWV as a function of diastolic BP for all young (solid thin line) and old (dashed thin line) Fisher rats, as well as for all young (solid thick line) and old (dashed thick line) SHRs.
