On age dependence of peripheral augmentation index
Sir: The possibility to continuously assess changes in blood pressure dictates the need to find proper ways of obtaining clinically relevant information from such signals. In the simplest linear case scenario pressure changes are directly proportional to volume changes. This could give some theoretical soundness to the use of photoplethysmographic signals for similar purposes1. Even when the PP...
متن کاملPeripheral "oscillatory" compliance is associated with aortic augmentation index.
The augmentation index (AIx) and "oscillatory" compliance (C(2)) are wave contour analysis parameters for the central aorta (P(ao)) and radial artery pressure wave (P(rad)), respectively. Both are sensitive to cardiovascular risk factors such as aging, hypertension, and diabetes and have been proposed as prognostic markers for cardiovascular disease. In this work, we studied the relation betwee...
متن کاملPeripheral augmentation index and wave reflection in the radial artery.
Peripheral Augmentation Index and Wave Reflection in the Radial Artery To the Editor: We were interested to read the recent article by Munir et al1 and congratulate them on making a valuable contribution to the field of pulse wave analysis. They and Payne and Webb, in their accompanying editorial,2 ponder why the late systolic shoulder (SBP2) corresponds so closely with central systolic blood p...
متن کاملPeripheral Augmentation Index is Associated With the Ambulatory Arterial Stiffness Index in Patients With Hypertension
BACKGROUND Vascular dysfunction is highly prevalent if not ubiquitous in patients with hypertension. We compared two different measures of vascular function obtained from digital volume waveforms with measures of ventricular-vascular load derived from 24-hour blood pressure (BP) recordings in patients with hypertension. METHODS Digital pulsatile volume waveforms were captured via plethysmogra...
متن کاملPeripheral augmentation index defines the relationship between central and peripheral pulse pressure.
Peripheral systolic blood pressure is amplified above central aortic systolic pressure, but the late systolic shoulder of the peripheral pulse may approximate central systolic pressure. Because late systolic pressure also determines the peripheral augmentation index, a measure of pressure wave reflection within the systemic circulation, this implies a direct relationship between amplification a...
