Outline of Research at the Start

心不全患者においては、脂肪酸代謝不全を来し、骨格筋内の脂肪濃度を増加させ、筋力低下・筋肉量減少からサルコペニアを来す。この骨格筋不全を防ぐために、非侵襲的な骨格筋における脂肪酸含有率測定方法を確立し、骨格筋脂肪化を抑制する脂肪酸を同定し、心不全患者におけるサルコペニアを防ぐ栄養療法を確立することである。

Outline of Final Research Achievements

We sought to establish a method for measuring fatty acid content in skeletal muscle using noninvasive MR spectroscopy and to establish a nutritional therapy to prevent sarcopenia in heart failure patients. We established a method to identify sarcopenia more sensitively than cross-sectional area of skeletal muscle by first quantifying lipids by peak values in MR spectroscopy, unsaturated fatty acids were found to be a therapeutic target for sarcopenia. These results may contribute to a new nutritional therapy for sarcopenia, especially in heart failure patients with increased skeletal muscle catabolism.

Academic Significance and Societal Importance of the Research Achievements

サルコペニアの治療標的として不飽和脂肪酸が治療標的の一つであることが明らかとなった。このようにMRスペクトロスコピーを用いた解析により、不飽和脂肪酸がサルコペニアの治療標的であることが明らかとなった。これらの成果は、今後サルコペニア特に骨格筋の異化が増強している心不全患者における新たな栄養療法に寄与すると思われる。
