Figure 2 Central pressure waveform. The height of the late systolic peak above the inflection defines the augmented pressure, and the ratio of augmented pressure to pulse pressure identifies the augmentation index (in percent).

Figure 3 Changes in pulse wave velocity, augmentation index and pulse pressure amplification in 40 hypertensive patients treated with nebivolol or atenolol for 4 weeks. *= p < 0.05; **= p < 0.01 vs Basal.
