| Outline of Final Research Achievements |
We analyzed the relationships between infiltrating inflammatory cells and clinical features in patients diagnosed with dilated cardiomyopathy clinically.
Among 128 patients who underwent myocardial biopsy, we obtained clinical data and pathological counts of T lymphocytes, B lymphocytes, macrophages, dendritic cells, regulatory T cells, and MHC. However, no significant relationship between clinical data and pathological results has been found. We believe the variety of diagnoses of dilated cardiomyopathy, the conditions, and artifacts of pathological specimen preparation were one of the problems. We are discussing this topic further with the other researchers outside; then we want to report the results after the fund period.

| Academic Significance and Societal Importance of the Research Achievements |
拡張型心筋症における慢性心筋内炎症細胞浸潤は、予後予測や病態理解において近年注目されている。本研究で得た臨床データと検体データ、もしくは非有意な結果となった原因を更に検証し、今後の自施設、他施設、両者における研究計画・遂行に役立てたい。
