| Outline of Final Research Achievements |
Purpose: The purpose of this study was to elucidate the differences between the measured values by echocardiography between at sitting and in supine positions. Subjects and Methods: We compared the echocardiographic parameters between at sitting and in supine positions in 28 patients without heart diseases and 10 patients with heart diseases. Results and Discussions: Both groups showed that the vena cava inferior diameters decreased and the left atrial diameters increased in supine position compared at sitting position. Both groups showed that E and E/A of the transmitral flow patterns increased in supine position compared with those at sitting position. These changes based on the patients’ posture may reflect alterations of preload of left ventricle. Conclusions: The differences between the measured values based on the patients’ posture should be considered when we perform echocardiography at sitting position.

超高齢化社会を迎え，転倒や診断の遅れを避けるという患者安全のために心エコーは座位で行うほうが望ましい場合がある。また実臨床では、臥位になれない緊急患者も多い。したがって座位のまま心エコーを行う必要性は高い。本研究では座位と臥位での心エコー計測値を比較した。本研究の結果、心エコーを座位で行う場合には心エコー計測値の差異をある程度考慮する必要はあるが、臨床的意義は臥位と同様に高いと考えられた。座位での心エコーの臨床的有用性を支持する結果であった。
