Abstract:Objective To explore the brachial-ankle pulse wave velocity (baPWV) in the same cohort longitudinally in order to investigate the decreasing rate of vasoactivity with aging. Methods Based on the people cohort in 2008 in Shenyang, the people were divided into ≤44-year-old, 45- to 54-year-old, 55- to 64-year-old, 65- to 74-year-old and ≥75-year-old groups according their age in the year of 2008. Biochemical methods were used to detect their blood lipid and glucose indices. A full-automatic arteriosclerosis detector was employed to measure blood pressures of bilateral brachial artery and anterior tibial artery (including systolic blood pressure, mean arterial pressure, diastolic blood pressure, and pulse pressure). Ankle-arm index (ABI and baPWV) were also calculated. The same tests were conducted again in 3 years later. There were totally 310 patients who fulfilled all detection. Self-control analysis on the vasoactivity was carried out. Results There were significant differences in baPWV and baPWV alteration among different age groups (P<0.01 for all). There was positive correlation of baPWV and baPWV alteration with age (P<0.01 for all). Self-control analysis showed baPWV was significantly different in the 2 times of examination (P<0.01), and baPWV alteration was more significant with aging (P<0.01). Conclusion There is association between getting older and change of baPWV. Progressively reduced vasoactivity caused by getting older becomes aggravated with aging.
