ELEVATED PERIPHERAL AUGMENTATION INDEX AND PULSE WAVE AMPLITUDE IN PATIENTS WITH HYPERTROPHIC CARDIOMYOPATHY

Augmentation index and aortic pulse wave velocity in patients with abdominal aortic aneurysms.

BACKGROUND Abdominal aortic aneurysm (AAA) is a severe disease that can prove fatal. Factors such as advanced age, male gender, family history and cigarette use increase the risk of AAA. These factors associated with AAA development also increase arterial stiffness. Aortic pulse-wave velocity (PWV) was measured as an index of aortic stiffness. The heart rate-corrected augmentation index (AIx@75...

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...

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

Vortex Formation Time Index in Patients With Hypertrophic Cardiomyopathy.

significantly higher proportion of IHIS in ICA plaques ipsilateral to the side of infarction in cryptogenic stroke patients (p <0.001), but not in patients with strokes from cardioembolism (p 1⁄4 0.76) or smallvessel occlusion (p 1⁄4 0.49). Our results suggest that some strokes from largeartery atherosclerosis are currently not being recognized as such because the plaque causes <50% stenosis. O...
