Objective To summarize the characteristics of common carotid arterial wave intensity (WI) in healthy volunteers and offer the normal reference values of WI. Methods Common carotid arteries (CCA) in 525 healthy volunteers were examined using Aloka Prosound α10 equipped with wave intensity software. The volunteers were divided into six group according to age,group A,＜20 years old;group B,20 - 29 years old;group C,30 - 39 years old;group D,40 - 49 years old;group E,50 - 59 years old and group F,≥60 years old. Carotid arterial wave intensity in normal subjects had two positive peaks, the first peak,W1 ,and the second peak, W2. Between the two positive peaks, a negative area (NA), the time interval between the R-wave of ECG and the first peak(R-W1 ) and that between the first and second peaks (W1-W2) were observed. Results ① 1050 common carotid arteries in 525 volunteers were studied. The mean values of W1,W2,NA,R-W1,and W1-W2 were (8332±4796) mmHg · m-1 · s-3,(1853±1143)mmHg · m-1 · s-3,(38 ± 26) mmHg · m-1 · s-2, (102 ± 19)ms and (266 ± 42)ms,respectively. ②These values were no significant between the left and right CCA in same group. W1 and NA were correlated with age ( r = - 0. 204 and r = -0.301, P ＜0. 001). W1 and NA in group A and B were significant increased than those in other groups( P ＜0. 05 or P ＜0. 001 ). ③There were statistical significances in W1 and W1-W2 of CCA between male and female. ④There were no statistical significances in all values in common carotid arteries of both sides (P ＞0. 05). Conclusions WI technique is useful for evaluating the dynamic behavior of the heart and the vascular system and their interaction. W1 is very sensitive to the changes in the working condition of the cardiovascular system.
