本事業のため既定の期間に米国に渡航を行い現地の研究者と連携しながら研究活動を行った (Kansas 大学 Mid-American Heart Institute ならびに Stanford 大学 Department of Cardiology) 。Mid-American Heart Institute とは、主に米国と日本の全国データと関東一円の地域データの比較検証を冠動脈疾患に関して行った。Stanford 大学とは主に心不全症例に対する診療データのアップデートされたコーディングを活用し、Frail指標を軸に据えた新たな予後予測モデルの作成に取り掛かっている。 For the present scientific project, we have started international collaborative work with Mid-American Heart Institute (MAHI) and Department of Cardiology, Stanford University in the United States. The collaborator in MAHI is Dr John A. Spertus, and we have compared the actual case-report from of the patient-based dataset on coronary artery disease (Keio interhospital cardiovascular studies [PCI] from Japan and National Cardiovascular Data Registry [NCDR] CathPCI in the US). Risk models related to catheter-based therapeutics were constructed and validated. In addition, direct comparison of patient and procedural characteristics, along with its trend was investigated. With Stanford University, we collaborated with Dr Paul A. Heidenreich. Administrative datasets in VA and NY State was used for this collaborative research. The main aims was to assess quality improvement measures in each countries (e.g. 30-day readmission in acute heart failure, frail index, or mortality in PCI)., 研究種目 : 国際共同研究加速基金 (国際共同研究強化) 研究期間 : 2017～2019 課題番号 : 16KK0186 研究分野 : 循環器内科
