Outline of Final Research Achievements |
Heart failure is a progressive condition in which the heart muscle couldn't pump enough blood. Advanced heart failure is a form of heart failure which has progressed to the most serious stage. Heart transplantation and implantable ventricular assist device revolutionized the management of advanced heart failure and drastically improved its survival. However, advanced heart failure is frequently complicated with comorbidities, such as renal dysfunction, hepatic dysfunction, pulmonary vascular failure, and sarcopenia. These comorbidities are known to worsen the morbidity and mortality in advanced heart failure, but the method of evaluation and prediction has not been well established. The current study revealed that urinary creatinine, sarcopenia indicator, and platelet count are associated with mortality or bleeding event in advanced heart failure.

Academic Significance and Societal Importance of the Research Achievements |
心不全患者では、全身への血の流れが悪くなることなどによる、全身の筋肉量の減少が多くの方で起こり、サルコペニアと呼ばれています。サルコペニアの標準的な評価方法はX線による被爆を伴いますが、尿クレアチニン総排泄量は尿検査だけで全身の筋肉量を推定することの出来る簡便な指標です。本研究により、重症心不全患者においても尿クレアチニン総排泄量から筋肉量を推定することが出来き、植込型補助人工心臓の手術後の経過を予測するのに有用であることが示されました。
