Summary of Activity

Heart failure is the symptom in which heart dysfunction eventually results in death due to insufficient delivery of oxygen and nutrients to peripheral organs. Pediatric heart failure is an important cause of death of children. Especially overt heart failure in the preweaning period is malignant and fulminant. Surprisingly, however, there are no specific drugs available for them. We are trying to develop novel drugs to enable these children to safely survive the unfortunately long waiting period by cardiac transplantation.

Research Subject

・ Development of drugs specific for pediatric heart failure

Outlook for Research

Treatment of pediatric heart failure has been long-standing unmet medical needs as there are no drugs with evidence due to the difficulties in conducting large pediatric clinical trials and low incentive of pharmaceutical companies. Our research from a basic aspect would shed light on solution of this inconvenient fact.

Outlook for Students After Graduation

Students can learn multidisciplinary approach including molecular biology to comparative integrative physiology in our laboratory. This will help them get their future scientific success.
