Arterial stiffening by blood pressure increase
In a recent issue of the Journal, Guo et al. examined progression of arterial stiffness in middle-aged men. In the report, the authors found positive association of changes in brachial–ankle pulse wave velocity (baPWV) with longitudinal changes in blood pressure (BP), and noted that the findings suggest arterial stiffening by longitudinal BP increase. However, the baPWV changes in the report could have reflected the pressure-dependent nature of baPWV.
