Kyoto Congestive Heart Failure (KCHF) Study: Rationale and Design.

Abstract

Aims: Over the last decade, major developments in medicine have led to significant changes in the clinical management of heart failure patients. This study was designed to evaluate the recent trends in clinical characteristics, management, and short-term and long-term prognosis of patients with acute decompensated heart failure (ADHF) in Japan. Methods and results: The Kyoto Congestive Heart Failure study is a prospective, observational, multicentre cohort study, enrolling consecutive ADHF patients from 19 participating hospitals in Japan from November 2014 to March 2016. A total of 4000 patients will be enrolled into the study and patients' anthropometric, socio-economic, and clinical data from hospital admission to discharge will be collected. In addition, in a pre-determined subgroup of patients (n=1500), a longitudinal follow-up for 2 years is scheduled. Conclusions: The Kyoto Congestive Heart Failure study will provide valuable information regarding patients with ADHF in the real-world clinical practice of Japan and will be indispensable for future clinical and policy decision-making with respect to heart failure.
