Peripheral Augmentation Index is Associated With the Ambulatory Arterial Stiffness Index in Patients With Hypertension

Figures

Figure 1. Association between peripheral arterial tonometery (PAT) derived augmentation index (AIx) and ambulatory arterial stiffness index (AASI).

Figure 2. Peripheral arterial tonometery (PAT) derived augmentation index (AIx) in nocturnal dippers versus non-dippers (adjusted for age, BMI, heart rate and mean arterial pressure). ^†Significantly different from dippers (P < 0.05).
