Abstract
Objective To explore the correlation of arterial velocity pulse index (AVI) and arterial pressure volume index (API) to age and brachial-ankle pulse wave velocity (baPWV),the independent predictors of arterial stiffening,and to evaluate their validity as arterial stiffness indices.Methods Volunteers were randomly recruited from the physical examination center,in total,140 volunteers were enrolled,including 110 healthy subjects (aged at 47.40±14.38 years) and 30 subjects with pure hypertension (aged at 53.50± 10.60 years);arterial pulse velocity detector and arterial stiffness device (BP-203RPEIII) were applied in detecting AVI,API,left brachial blood pressures (BPs) and bilateral baPWVF of the volunteers;the clinical data of the volunteers including age,sex and blood biochemical index were recorded;Pearson Correlation Analysis was applied in exploreing the correlation of AVI and API to age and baPWV while t test was applied in detecting the difference in the explored data between the subjects with hypertension and the norm of same age and gender.Results AVI of the subjects in healthy group was in strong linear correlation with age (r=0.706,P=0.000) and was obviously correlated to baPWV (r=0.599,P=0.000) and API was also correlated to age and baPWV but was in a much weaker correlation than that AVI was in;the mean of AVI,API and baPWV of the subjects with hypertension were higher than those of the norm of same age and gender with a statistical difference.Conclusions AVI is of similar role with baPWV in detecting the arterial stiffening caused by age and hypertension;API is of certain value in evaluating the arterial elasticity in patients with hypertension though it has a weaker correlation with age in the healthy due to its limitation as a a stiffness index of peripheral (i.e.,brachial) artery.关键词
