Research Design: Multicenter observational study (non-interventional, non-invasive, single-arm study)
The values of data from the RST calculation program during the study will be blinded to researchers and study subjects.

Research Summary: Respiratory Stability Time (RST) is a physiological indicator that quantifies respiratory stability. RST is automatically calculated from body motion signals extracted by a motion sensor placed on bedding. It has been suggested that RST can detect worsening heart failure in outpatients before the onset of heart failure symptoms.
This study investigates whether RST can detect worsening heart failure earlier than conventional heart failure assessment indicators in patients receiving disease management through outpatient treatment.
