Assessment of Arterial Stiffness Using the Cardio-Ankle Vascular Index.
BACKGROUND Arterial stiffness is an independent predictor of outcomes for patients with cardiovascular disease. Although measurement of pulse wave velocity is a widely accepted, noninvasive approach for the assessment of arterial stiffness, its accuracy is affected by changes in blood pressure. SUMMARY The cardio-ankle vascular index (CAVI) is an index of the overall stiffness of the artery f...
متن کاملDigital Photoplethysmography for Assessment of Arterial Stiffness: Repeatability and Comparison with Applanation Tonometry
INTRODUCTION Arterial stiffness is an independent risk factor for cardiovascular morbidity and can be assessed by applanation tonometry by measuring pulse wave velocity (PWV) and augmentation index (AIX) by pressure pulse wave analysis (PWA). As an inexpensive and operator independent alternative, photoelectric plethysmography (PPG) has been introduced with analysis of the digital volume pulse ...
متن کاملAmbulatory arterial stiffness index: determinants and outcome.
OBJECTIVES We hypothesized that one minus the slope of diastolic on systolic blood pressure in individual 24-h ambulatory blood pressure recordings (ambulatory arterial stiffness index) might reflect arterial stiffness and predict cardiovascular mortality. METHODS In volunteers and a population recruited in China, we studied concordance between ambulatory arterial stiffness index and establis...
متن کاملAmbulatory arterial stiffness index: rationale and methodology.
OBJECTIVES Increased arterial stiffness is associated with the development of cardiovascular disease and may even predict its development at an early stage. Increased pulse pressure is seen as a marker of increased arterial stiffness and can be readily measured by ambulatory blood pressure monitoring. We propose another surrogate measure of arterial stiffness derived from ambulatory blood press...
متن کاملAssessment of Effects of Visually-Induced Motion Sickness Using Physiological Index Obtained from Photoplethysmography
A human watching a swaying image displayed on a wide-field display or screen sometimes suffers from visually-induced motion sickness (VIMS) that causes symptoms related to the autonomic nervous system such as nausea, vomiting, and dizziness. The previous study indicated that the maximum cross-correlation coefficient (ρmax) between blood pressure and heart rate whose frequency components are lim...
