ABSTRACT
Human aging, the process of arterial stiffness occurs rapidly, which later results in structure change and dysfunction in blood circulation. The purpose of this study was to determine the cardio-ankle vascular index (CAVI) of elderly population in different regions of Mongolia and compare the result. In accordance with Mongolian nationwide Human Longevity Study, 1114 elderly subjects (male over 60 age, female over 55 age) were examined in Ulaanbaatar city, Baruun, Khangai area. CAVI was calculated automatically from the pulse volume record, blood pressure and the vascular length from heart to the ankle. Cardio-ankle vascular index were evaluated by VaSera VS-1000 (FUKUDA DENSHI, JAPAN). Average decline of CAVI was about 8.88±1.44 in a per decade. CAVI was correlated with age (r=0.415, p<0.01). CAVI was significantly correlated with age, and Ulaanbaatar city’s elderly people arterial stiffness is more changed other areas. Arterial stiffness male elderly people was changed more than female people.
