After obtaining my medical degree from Tokyo Medical and Dental University (Tokyo, Japan), I started my clinical training at Japanese Red Cross Musashino Hospital (Tokyo, Japan). After 2 years of internal medicine residency, I continued my fellowship training in cardiology for 3 additional years at the same institution. My primary interest was in heart failure, and I have been closely involved with clinical research program at the Department of Cardiology, Keio University School of Medicine. In 2016, I joined their PhD program in the clinical research, with main focus on construction of large-scale database. My passion lies to seek for better outcomes of our patients with heart failure.
