Outline of Final Research Achievements

In this project, we established a technology and system for early detection and prevention of atrial fibrillation and angina pectoris, which are causative diseases and signs of cardiogenic cerebral infarction and myocardial infarction. Specifically, the team acquired vital data using sensors with medical device-level measurement accuracy, and constructed a hybrid AI judgment system for this data. Since atrial fibrillation and angina pectoris do not always occur on a regular basis, it is difficult to detect them completely during regular checkups. In particular, it is estimated that there are as many as 800,000 patients with hidden atrial fibrillation. To solve this problem, we demonstrated that medical device-level health monitoring is possible in daily life, and furthermore, that disease detection is possible through hybrid AI judgment.

Academic Significance and Societal Importance of the Research Achievements

医療資源が十分とはいえない中で高齢化社会を迎え、医療に対する需要が伸びていく日本の現状に対して、医療コストと被測定者に負担をかけることなく、日常生活の中で、重篤な疾患に繋がる前段階の病気を検出する技術・システムを構築したことは極めて社会的意義が高いと考えられる。また、患者数が極めて多いことから、多数の患者の健康寿命の延伸に寄与することが期待され、経済的な意義も大きい
また、計算負荷の小さい方法でハイスペック解析に匹敵する疾患判定精度を成しえたことは非常に学術的意義が高いと考えられる。
