Outline of Final Research Achievements

Predicting the progression of various coronary artery diseases and early intervention are one of the important issues in cardiovascular medicine. Our aim of this study was to examine the relationship between neutrophil Rho kinase activity, which is focused as a biomarker for predicting the progression of coronary artery diseases, and the progression of coronary artery diseases. However, it was judged that the measurement system of Rho kinase activity was unstable and it was difficult to make an accurate measurement, and it was abandoned to use Rho kinase activity as a biomarker for predicting the progression of coronary artery disease. On the other hand, under the current research grant, we investigated factors related to the progression of coronary artery disease after heart transplantation.

Academic Significance and Societal Importance of the Research Achievements

ドナー心由来の持ち込み病変の存在が、心移植後1年目から3年目までのCAVの進行を予測すること（Transplantation 2017; 101:1310-1319）、エベロリムスのCAV進行に対する抑制効果は、血管内膜の増殖の抑制だけでなく、血管外膜の縮小変化の抑制によってもたらされること、また、エベロリムスによるCAV進行の抑制効果は、心移植後急性期だけでなく、維持期においても認められることを報告した（International Journal of Cardiology 2016; 203:307-314）。これらの成果は、本邦での心移植後患者の治療戦略に影響を与える成果である。
