| Outline of Final Research Achievements |
A study on health management index values using AI analysis was conducted using the waveform of Korotkoff sounds during blood pressure measurement. It was clarified that the waveforms of a heart disease-experienced person and a healthy person can be converted into images that retain the characteristics of the waveforms using polar coordinates. Furthermore, by calculating the distance between the target images by judging the degree of similarity of the images and arranging them on the three-dimensional coordinates, a three-dimensional bird's-eye view of each image position was created. By using this figure, it was clarified that there is a possibility of obtaining a health management index value from the positional relationship with each disease image.

| Academic Significance and Societal Importance of the Research Achievements |
通常の血圧測定の際に、計測できるコロトコフ音波形により健康指標値が得られるのであれば、被験者に負荷をかけず、循環器系アセスメントが可能になるため、社会的な意義が大きい。
