Introduction: Arteriosclerosis is a lifestyle-related disease that is a cause of a cerebrovascular disease, and therefore evaluating a risk of arteriosclerosis was the object of this study. Pulse wave velocity (PWV) and systolic pressure (Sys) were measured in this study with the aim of making an index to evaluate the risk of developing arteriosclerosis.
Method: The PWV of confinement-related arteriosclerosis patients with low-risk ankle-brachial pressure index of more than 0.9 was measured at a medical office in Nagano City. The ages of 23,387 patients were 11-100 years (male 9,417; female 13,970). We assumed a vertical axis of all subjects’ PWV value and pulled the regression line into a cross axis with Sys. The whole sample was classified in 4 subgroups that were older than 70s, for 60s as follows for 50s, 40s and this made for a similar regression. Furthermore, a regression line with each subject’s PWV value and Sys value compared PWV of average systolic pressure (Pas) value was investigated. The statistical probability level was equal to or less than 5%.
Result and Discussion: By comparison with the whole, a regression line with Pas was a low value of 28.4%. The crowd that regression line is equal to whole’s regression line and Pas is a low value is 23.4%. The flock that regression line is equal to whole’s regression line and Pas is a high value is 27.3%. As the generation rose from the less than 40s to more than 70 age group, ratios of the person who belonged to group that a degree of regression line and Pas is high score is increased, and it was concluded that aging makes a blood vessel tense and a blood vessel tended to be more easily tense with increased blood pressure.
