Interaction between pulse wave velocity, augmentation index, pulse pressure and left ventricular function in chronic heart failure

Endothelial function is associated with pulse pressure, pulse wave velocity, and augmentation index in healthy humans.

Arterial stiffness is an independent predictor of mortality and is regulated by a number of factors, including vascular smooth muscle tone. However, the relationship between endothelial function and definitive measures of arterial stiffness and wave reflections has not been described in healthy individuals. Therefore, we tested the hypothesis that endothelial function is inversely correlated wi...

The 24-hour pulse wave velocity, aortic augmentation index, and central blood pressure in normotensive volunteers

The purpose of this study was to examine the pulse wave velocity, aortic augmentation index corrected for heart rate 75 (AIx@75), and central systolic and diastolic blood pressure during 24-hour monitoring in normotensive volunteers. Overall, 467 subjects (206 men and 261 women) were recruited in this study. Participants were excluded from the study if they were less than 19 years of age, had b...

Aortic pulse wave velocity in normals and heart failure patients

Background Aortic compliance (AC) can be evaluated noninvasively and its reduction with aortic pathology and age in normals has been demonstrated with both MRI and Doppler echo methods. Aortic pulse wave velocity (PWV), a measurement of the flow pulse traveling along aorta as a surrogate for AC, can be assessed using a single breath-hold phase contrast (PC) imaging technique. Congestive heart f...

Diabetic retinopathy is associated with pulse wave velocity, not with the augmentation index of pulse waveform

BACKGROUND To investigate the clinical differences between pulse wave velocity and augmentation index in diabetic retinopathy. METHODS The subjects were 201 patients with type 2 diabetes. These subjects were measured for both augmentation index (AI) and brachial-ankle pulse wave velocity (baPWV) by a pulse wave analyzer. The relationships between AI, baPWV, and diabetic retinopathy were exami...
