AI Article Synopsis
- Carotid-femoral pulse wave velocity is the standard method for measuring central arterial stiffness noninvasively.
- The test requires subjects to lie down quietly for at least 10 minutes while blood pressure and pressure waveforms from femoral and carotid arteries are recorded.
- The pulse wave velocity is calculated by dividing the distance the pulse wave traveled by the time it took to get there, with measurements taken in triplicate for accuracy.
Article Abstract
Carotid-femoral pulse wave velocity is considered the gold standard for measurements of central arterial stiffness obtained through noninvasive methods(1). Subjects are placed in the supine position and allowed to rest quietly for at least 10 min prior to the start of the exam. The proper cuff size is selected and a blood pressure is obtained using an oscillometric device. Once a resting blood pressure has been obtained, pressure waveforms are acquired from the right femoral and right common carotid arteries. The system then automatically calculates the pulse transit time between these two sites (using the carotid artery as a surrogate for the descending aorta). Body surface measurements are used to determine the distance traveled by the pulse wave between the two sampling sites. This distance is then divided by the pulse transit time resulting in the pulse wave velocity. The measurements are performed in triplicate and the average is used for analysis.
