Pulse Wave Velocity Testing in the Baltimore Longitudinal Study of Aging

摘要: Carotid-femoral pulse wave velocity is considered the gold standard for measurements of central arterial stiffness obtained through noninvasive methods1. Subjects are placed in supine position and allowed to rest quietly at least 10 min prior start exam. The proper cuff size selected a blood pressure using an oscillometric device. Once resting has been obtained, waveforms acquired from right femoral common carotid arteries. system then automatically calculates transit time between these two sites (using artery as surrogate descending aorta). Body surface used determine distance traveled by sampling sites. This divided resulting velocity. performed triplicate average analysis.
