Outline of Final Research Achievements |
The purpose of this study was to clarify whether a new index, ear blood flow (EBF), could be incorporated into the cardiopulmonary stress test (CPX) for cardiac patients to provide a new index for prognosis and exercise therapy. Furthermore, we aimed to develop a more effective and simple treatment method using EBF as an indicator. The present study revealed that patients with heart disease who have a low exercise tolerance have a decreased EBF with exercise. Since maximal oxygen uptake is a prognostic indicator of cardiac disease, these results suggest that EBF may be a prognostic indicator of cardiac disease. Furthermore, preliminary experiments were conducted on healthy subjects, and it was confirmed that EBF increased to the same degree as that at maximal exercise intensity after a 20-minute lower-leg bath at 42°C.

Academic Significance and Societal Importance of the Research Achievements |
これまでの血流計は安静時の測定がほとんどで,運動中の末梢循環不良については十分に検討されていなかった.しかし,運動療法を行う上では運動負荷に対する末梢循環を知ることが有用であり,本研究でCPXに伴うEBFの挙動を定量的に評価することは新しい治療法の糸口となる.その1つとして本研究では汎用性の高い下腿浴に着目し,最適な条件を検証した.これには運動療法の効果を底上げすることが期待できる.
