Can Augmentation Index Quantify Impact of Pulse Wave Reflection in Isolated Systolic Hypertension?

Aortic pulse wave velocity, reflection site distance, and augmentation index.

Wave reflection in systolic hypertension: smaller stature, shorter aorta: higher pulse pressure?

Wave Reflection in Systolic Hypertension: Smaller Stature, Shorter Aorta: Higher Pulse Pressure? To the Editor: In a recent issue of Hypertension, Mitchell et al1 suggested that, among patients with systolic hypertension, reduced aortic diameter and increased wall stiffness, rather than premature wave reflection, are primarily responsible for increasing pulse pressure (PP). We share the concern...

Peripheral 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...

Aortic diameter, wall stiffness, and wave reflection in systolic hypertension.

Systolic hypertension is associated with increased pulse pressure (PP) and increased risk for adverse cardiovascular outcomes. However the pathogenesis of increased PP remains controversial. One hypothesis suggests that aortic dilatation, wall stiffening and increased pulse wave velocity result from elastin fragmentation, leading to a premature reflected pressure wave that contributes to elevat...

The relationship between body mass index and pulse pressure in older adults with isolated systolic hypertension.

BACKGROUND Many longitudinal studies have reported excess cardiovascular mortality among lean hypertensive subjects, suggesting that obesity may mitigate the cardiovascular risk of hypertension. Available evidence also suggests that in middle-aged and older hypertensive subjects, pulse pressure may be a better predictor of cardiovascular complications. However, there are limited data on the rel...
