MULTIPLE FACTORS ANALYSIS FOR THE FACTORS ON THE BRACHIAL-ANKLE PULSE WAVE VELOCITY

[Objective] To analyze the multiple clinical factors on affect brachial-ankle pulse wave velocity(baPWV) .[Methods] 278 healthy were enrollcd randomly and measured left and right baPWV with Japan's COLIN arteriosclerosis instrument.People were divided into four groups based on the value of baPWV:﹤1 400 cm / s as group one(the normal group);1 400-1 600 cm / s as group one;1 600-1 800 cm / s as group three;﹥1 800 cm / s as group four.Clinical data were collected and to be statistical analysed among the four groups.[Results] ① When compare group one with group two to four, there was no significant difference with total cholesterol(TCH), high density lipoprotein cholesterol(HDL), and low density lipoprptein cholesterol(LDL)(P ﹥ 0.05).On the contrast, the level of age, systolic blood pressure(SBP) , diastolic blood pressure(DBP), mean artery pressure(MAP), pulse pressure(PP), fasting blood glucose(Glu), brachial-ankle pulse wave velocity(baPWV) were significantly higher than that in control group(P﹤0.05).With the level of baPWV increasing, all the indexes above were increasing(P﹤0.05).② Age, SBP, DBP, MAP, PP, HR, Glu and LDL were significant correlated with baP-WV by partial correlated analysed.③ A stepwise multiple regression analysis demomestrated that SBP, HR and age were positively related to baPWV(P﹤0.001).[Conclusion] Age, SBP, DBP, MAP, PP, HR, Glu and LDL were significant correlated with baPWV.Especially SBP, HR and age were positively related to baPWV.The SBP, HR and age were important risk factors for artery elasticity.
