Beta stiffness--setting age standards

Beta stiffness index is one of the most commonly used measures of depicting mechanical arterial properties and development of preclinical atherosclerosis. Main influences on its value hold age and blood pressure levels. The goal of this study was to determine age standards of beta stiffness index on common carotid artery in our population using a formula modified by Kawasaki. The study was conducted in 150 healthy volunteers aged 25-75 on an Aloka 5500-SSD Pro-sound ultrasound platform using B and M modes. The data obtained were analyzed by appropriate statistical methods. Study results confirmed linear relationship of beta index and age. Calculation of beta index is applicable for assessment and monitoring of vascular physiology changes because it is simple for use, prompt in analysis and suitable for bed-side evaluation.
