To explore the effect of blood lipid and lipoprotein ratios on the change of brachial-ankle pulse wave velocity (baPWV) among prehypertensive subjects. 11 611 subjects with normal blood pressure (BP) were divided into two groups, which was one with optimal blood pressure (BP<120/80 mmHg) and the other with prehypertension (BP:120-139/80-89 mmHg). Height, weight, baPWV, fasting blood-glucose, TC, TG, LDL-C and HDL-C were detected. The abnormal rate of baPWV in prehypertension group was obviously higher than that in the optimal blood pressure group. For optimal blood pressure group, the abnormality of TG, TC, LDL-C, TC/HDL-C as well as LDL-C/HDL-C, caused the increase of baPWV significantly (P < 0.001). For prehypertensive group, the abnormality of TC and LDL-C caused the significant increase of baPWV (P < 0.001). Results from logistic regression analysis showed that except for age, BMI and fasting blood-glucose, TC/HDL-C increasing was the independent risk factor in optimal blood pressure group, while TG increasing was for the prehypertension group. With different normal BP level, both abnormality of blood lipid and lipoprotein ratio were the independent risk factors for baPWV increasing.
