Increased central pulse pressure and augmentation index in subjects with hypercholesterolemia.
OBJECTIVES The goal of this study was to investigate the relation between serum cholesterol, arterial stiffness and central blood pressure. BACKGROUND Arterial stiffness and pulse pressure are important determinants of cardiovascular risk. However, the effect of hypercholesterolemia on arterial stiffness is controversial, and central pulse pressure has not been previously investigated. METH...
متن کاملReference Values for the Augmentation Index and Pulse Pressure in Apparently Healthy Korean Subjects
BACKGROUND AND OBJECTIVES Arterial stiffness is a precursor to premature cardiovascular disease. The augmentation index (AI) and pulse pressure (PP) are cardiovascular risk factors. The aim of this study was to define the diagnostic values of the AI and PP from the peripheral arterial and central aortic waveforms in healthy subjects. SUBJECTS AND METHODS We recruited 522 consecutive subjects ...
متن کاملThe 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...
متن کاملEndothelial 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...
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...
