Mean cfPWV, path length, transit time and heart rate for the two methods of assessing cfPWV
n=1122 | Sphygmocor | Vicorder | Diff | P value |
cfPWV (m/s) | 10.28±2.6 | 10.05±1.7 | 0.23 (0.10–0.37) | <0.001 |
Path length (mm) | 423±37 | 693±44 | −270 (−272 – −268) | <0.001 |
Transit time (ms) | 43.89±10.31 | 70.76±11.70 | −26.87 (−27.50– −26.24) | <0.001 |
Heart rate (bpm) | 59.68±11.52 | 59.93±10.08 | −0.26 (−0.69–0.18) | 0.25 |
cfPWV, carotid–femoral pulse wave velocity; Diff, difference between Sphygmocor measures and Vicorder measures, calculated as Sphygmocor minus Vicorder.
