Figure 1. Comparison of the single cuff oscillometric cuff method (Arteriograph) and pulse wave analysis with applanation tonometry (SphygmoCor) concerning systolic aortic BP (SBP) (a), diastolic aortic BP (DBP) (b), aortic pulse pressure (PP) (c), aortic mean arterial pressure (MAP) (d), augmentation index (AIx) (e), and pulse wave velocity (PWV) (f).

Figure 2. Bland-Altman analyses of the difference in mean values obtained by the single cuff oscillometric cuff method (Arteriograph) and by pulse wave analysis with applanation tonometry (SphygmoCor). Systolic aortic BP (SBP) (a), diastolic aortic BP (DBP) (b), aortic pulse pressure (PP) (c), aortic mean arterial pressure (MAP) (d), augmentation index (AIx) (e), and pulse wave velocity (PWV) (f).

Figure 3. Relative changes in BP and vascular function by treatment, presented as mean values ± SEM. SBP: systolic blood pressure; DBP: diastolic blood pressure; AIx: augmentation index; PWV: pulse wave velocity. Absolute changes for doxazosin and ramipril were −4.2 ± 3.0 and −17.1 ± 2.3 mm Hg for brachial SBP, −4.3 ± 3.4 and −20.9 ± 2.7 mm Hg for aortic SBP, −3.4 ± 1.4 and −10.7 ± 1.6 mm Hg for brachial DBP, −2.7 ± 1.5 and −10.8 ± 1.5 mm Hg for aortic DBP, −2.2 ± 1.4 and −6.2 ± 1.6% for AIx, −0.6 ± 0.2 and −0.4 ± 0.2 m/s for PWV, and 3.2 ± 1.5 and 4.2 ± 1.6 ms for transit time, respectively. Significance values for univariate analyses are denoted as *p < .05,**p < .01, and ***p < .001. Multivariate analyses are presented in .
