Outline of Final Research Achievements

Relationship between cardio-ankle vascular index (CAVI) and stiffness of the aorta and iliac arteries was evaluated using computed tomography. In this study, maximum thickness and aortic calcification of the aorta and iliac arteries were measured for use as a marked for arterial stiffness. CAVI had a positive correlation with maximum thickness and aortic calcification score (ACS) in the thoracoabdominal and abdominal aorta (from the inferior border of the 12th spinal body to aortoiliac bifurcation). Additionally, CAVI had a positive correlation with ACS in iliac arteries.
