Comparison of the aortic pulse wave velocity results measured by three different devices among hypertensive patients
open access
Abstract
Material and methods Study population consisted of 64 patients with mild to moderate primary arterial hypertension, 39 male and 25 female (mean age = 54.6 ± 13.6 yrs.) In this group we performed in the same time PWV examination using three mentioned above devices.
Results PWV measured by Complior device (10.2 ± 2.7 m/s) was significantly higher than obtained using SphygmoCor (9.54 ± 2.6 m/s, p < 0.001) or Arteriograph (9.2 ± 2.5 m/s, p < 0.001). PWV values obtained by each device were in significant correlations with each other: PWV-Complior vs. PWV-SphygmoCor, r = 0.96 (p < 0.001); PWV-Complior vs. PWV-Arteriograph, r = 0.41 (p < 0.01); PWV-Arteriograph vs. PWV-SphygmoCor, r = 0.34 (p < 0.05). In the Bland-Altman analysis performed for each pair of PWVs (obtained by compared devices) the plot - means/differences indicate that measured values were comparable i.e. differences/means below 1.96 SD. In the multiple regression models PWV-SphygmoCor depends significantly on age (p = 0.022, r = 0.10, R2 = 0.65), PWV-Complior on age (p = 0.001, r = 0.10, R2 = 0.63), heart rate (p = 0.028, r =0.07, R2 = 0.63) and central (aortic) pulse pressure (p = 0.019, r = 0.007, R2 = 0.63). PWV-Arteriograph at R
Conclusions Aortic PWV values measured by Complior device were higher than obtained using SphygmoCor and Arteriograph, two last devices did not differ in this matter. All three devices measured the same variable aortic PWV with comparable accuracy. Among patients with arterial hypertension age, gender, body height, heart rate and pulse pressure influenced significantly aortic PWV.
